Protein is an essential part of our diets. Proteins are large, complex molecules resembling tangled strings of beads. Each of the “beads” on the string is one of a group of smaller molecules called amino acids. Amino acids are composed of carbon, oxygen, hydrogen, and nitrogen, and some contain sulfur.

Using the amino acids from the protein you eat, the body makes more than 50,000 different proteins. These proteins are the main structural elements of our skin, hair, nails, cell membranes, muscles, and connective tissue.

Collagen, the main protein in our skin, provides a barrier to the invasion of foreign substances. Proteins in cell membranes determine what substances can enter and exit cells.

Our muscles, which contain some 65 percent of the body’s total protein, give our bodies their shape and strength.

Proteins in connective tissues such as tendons, ligaments, and cartilage enable our skeletons to function, form internal organs, and hold the organs in place. Proteins in the blood carry oxygen to all cells and remove carbon dioxide and other waste products.

The proteins in muscle, connective tissue, and blood make up most of the protein in the body. Other proteins called enzymes accelerate metabolic processes, and still other proteins and amino acids are hormones and neurochemicals, the substances that deliver signals throughout the body and regulate all metabolic processes.

During periods of growth, our bodies must manufacture and store large amounts of protein. Therefore, the requirement for protein in our diets is higher during growth.

But even when we are not growing, each of the unique proteins in the body has a finite lifespan and must be replaced continuously. So the need for protein never ends.

Dietary Protein and Body Protein

The thousands of proteins that make up our bodies are assembled on demand from some 20 different amino acids. What are these amino acids, and where do they come from?

The protein from the meat we ate last night is not directly incorporated into our muscles. The proteins in the foods we eat are digested first into small “peptides.” Some of these peptides are further digested into their constituent amino acids. Only amino acids and small peptides are actually absorbed by the small intestine into the bloodstream.

They are then delivered to the liver, muscles, brain, and other organs, where they are used to make new proteins or converted to other amino acids needed by those organs. Of the 20 amino acids that make up all proteins, 9 are considered “essential” because they cannot be made in our bodies and must be obtained from the foods we eat. Of the remaining 11, some are essential for infants and persons with certain diseases.

The rest of the amino acids are considered “nonessential,” because our bodies can make them in adequate amounts, if necessary. Nevertheless, they are easily supplied by eating a well-balanced diet that includes a variety of foods.

Most foods contain protein. Some foods are better sources of protein than others. “Complete” proteins are those that contain all the essential amino acids in amounts needed to synthesize our body’s proteins. The best sources of complete protein are lean meats and poultry, fish, low-fat dairy products, and eggs.

The grains and cereals group of foods, are excellent sources of protein, but because these proteins often lack one or more essential amino acids, they are called “incomplete” proteins.

For example, the proteins in corn are low in the essential amino acids lysine and tryptophan, and wheat is low in lysine. In contrast, legumes tend to be rich in lysine but a bit low in methionine. Among the legumes, soybeans contain the most complete protein.

Does this mean you must eat meat, eggs, and dairy products (foods of animal origin) to get all the amino acids you need? Not at all.By eating a variety of different foods, including grains and legumes, you are likely to get all the amino acids you need and in the correct amounts.

People of many cultures and vegans (vegetarians who eat no foods of animal origin) get adequate amounts and types of protein by eating various combinations of plant proteins including beans, corn, rice, and other cereal grains. Although it was once thought necessary to combine these foods at the same meal, nutrition experts now agree that they can be eaten at various times throughout the day.

When we eat grains and legumes, rather than foods of animal origin (a more frequent source of protein in our diets), we gain additional health benefits. Whole-grain foods and legumes are rich in vitamins, minerals, fiber, and other substances that optimize health.

If that does not seem like reason enough to make the trade, grains and legumes lack the high levels of saturated fat present in foods of animal origin, which, as you will learn below, are linked to many diseases.

Contrary to popular belief, simply eating more dietary protein, in excess of recommended amounts, will not result in bigger muscles. Our bodies do not store excess protein.

If we eat more protein than our bodies need to replenish the amino acids we have used during the day, the excess amino acids are converted to, and stored as, fat. Dietary protein, like carbohydrates, supplies about 4 calories of energy per gram.

Because our requirements for protein mainly depend on our body’s size, our need for protein increases during times of rapid growth. Therefore, the recommendations for protein are age-dependent and are slightly higher for pregnant and breastfeeding women than for other adults.

The carbohydrates are a vast and diverse group of nutrients found in most foods. This group includes simple sugars (like the sugar you add to your morning coffee) and complex forms such as starches (contained in pasta, bread, cereal, and in some fruits and vegetables), which are broken down during digestion to produce simple sugars.

The main function of the simple sugars and starches in the foods we eat is to deliver calories for energy. The simple sugar glucose is required to satisfy the energy needs of the brain, whereas our muscles use glucose for short-term bouts of activity.

The liver and muscles also convert small amounts of the sugar and starch that we eat into a storage form called glycogen. After a long workout, muscle glycogen stores must be replenished. Both simple sugars and starches provide about 4 calories per gram (a gram is about the weight of a paper clip).

Because carbohydrates serve primarily as sources of calories (and we can get calories from other macronutrients), no specific requirement has been set for them. But health experts agree that we should obtain most of our calories (about 60 percent) from carbohydrates. Our individual requirements depend on age, sex, size, and activity level.

In contrast to the other carbohydrates, fiber (a substance contained in bran, fruits, vegetables, and legumes) is a type of complex carbohydrate that cannot be readily digested by our bodies. Even though it isn’t digested, fiber is essential to our health. Nutrition professionals recommend 25 to 30 grams of fiber daily.

Simple Sugars

Simple sugars make foods sweet. They are small molecules found in many foods and in many forms. Some simple sugars occur naturally in foods. For example, fructose is the sugar that naturally gives some fruits their sweet flavor.

Table sugar, the sugar that we spoon onto our cereal and add to the cookies we bake, also called sucrose, is the most familiar simple sugar. A ring-shaped molecule of sucrose actually consists of a molecule of fructose chemically linked to a molecule of another simple sugar called glucose.

Sugars such as fructose and glucose are known as monosaccharides, because of their single (mono) ring structure, whereas two-ringed sugars such as sucrose are known as disaccharides. Another disaccharide, lactose, the sugar that gives milk its slightly sweet taste, consists of glucose linked to yet another simple sugar called galactose.

The inability to digest lactose to its constituent sugars is the cause of lactose intolerance, a condition common to adults of Asian, Mediterranean, and African ancestry.

The table sugar that we purchase is processed from sugar cane or sugar beets. As an additive to many different types of prepared or processed foods, sucrose adds nutritive value (in the form of calories only), flavor, texture, and structure, while helping to retain moisture.

Today, sucrose is most often used to sweeten (nondietetic) carbonated beverages and fruit drinks (other than juice), candy, pastries, cakes, cookies, and frozen desserts. One of the most commonly consumed forms of sugar is called high-fructose corn syrup.

High-fructose corn syrup is also commonly used to sweeten sodas, fruit drinks (not juices), some ice creams, and some manufactured pastries and cookies. Other forms of sucrose include brown sugar, maple syrup, molasses, and turbinado (raw) sugar

Foods that are high in added sugar are often low in essential nutrients such as vitamins and minerals. Unfortunately, these foods are often eaten in place of more nutrient-rich foods such as fruits, vegetables, and low-fat whole-grain products, and they may prevent us from obtaining essential nutrients and lead to weight gain.

Nutritionists are concerned by the enormous increase in sugar consumption by Americans during the past 30 years, particularly because much of this sugar is in the form of soft drinks. On average, teens today drink twice as much soda as milk, and young adults drink three times as much soda as milk.

As a result, their intake of calcium-rich foods is low, a factor that is thought to contribute to lower bone mass. This can lead to an increased risk of bone problems as we grow older.

The increase in sugar consumption also has been attributed to the increasing availability of low-fat versions of such dessert and snack foods as cookies, cakes, and frozen desserts. Often, the sugar content of these foods is high because sugar is used to replace the flavor lost when the fat is decreased.

Sugar promotes tooth decay, when consumed in forms that allow it to remain in contact with the teeth for extended periods. Thus, foods that are high in sugar, or sugar and fat, and have few other nutrients to offer  ans should be eaten sparingly.

In contrast, choosing fresh fruits, which are naturally sweetened with their own fructose, or low-fat yogurt, which contains lactose (natural milk sugar), allows us to get the vitamins and minerals contained in those foods as well as other food components that contribute to health but may not have yet been identified.

On the positive side, there is no credible evidence to demonstrate that sugar causes diabetes, attention deficit hyperactivity disorder, depression, or hypoglycemia. No evidence has been found that sugar-containing foods are “addictive” in the true sense of the word, although many people report craving sweet foods, particularly those that are also high in fat.

Fish can usually be purchased at a lower price than meat, and for this reason possesses an economic advantage over it. Besides the price, the substitution of fish for meat makes for economy in a number of ways to which consideration is not usually given.

These will become clearly evident when it is remembered that nearly all land animals that furnish meat live on many agricultural products that might be used for human food. Then, too, other foods fed to animals, although not actually human foods, require in their raising the use of soil that might otherwise be utilized for the raising of food for human beings. This is not true in the case of fish.

They consume the vegetation that grows in lakes, streams, and the ocean, as well as various kinds of insects, small fish, etc., which cannot be used as human food and which do not require the use of the soil.

In addition, much of the food that animals, which are warm-blooded, take into their bodies is required to maintain a constant temperature above that of their surroundings, so that not all of what they eat is used in building up the tissues of their bodies.

With fish, however, it is different. As they are cold-blooded and actually receive heat from their surroundings, they do not require food for bodily warmth. Practically all that they take into the body is built up into a supply of flesh that may be used as food for human beings.

With fish, as with other foods, some varieties are sought more than others, the popularity of certain kinds depending on the individual taste or the preference of the people in a particular locality.

Such popularity, however, is often a disadvantage to the purchaser, because a large demand for certain varieties has a tendency to cause a rise in price. The increased price does not indicate that the fish is of more value to the consumer than some other fish that may be cheaper because it is less popular, although quite as valuable from a food standpoint.

The preference for particular kinds of fish and the persistent disregard of others that are edible is for the most part due to prejudice. In certain localities, one kind of fish may be extremely popular while in others the same fish may not be used for food at all.

Such prejudice should be overcome, for, as a matter of fact, practically every fish taken from pure water is fit to eat, in the sense that it furnishes food and is not injurious to health. In addition, any edible fish should be eaten in the locality where it is caught.

The transportation of this food is a rather difficult matter, and, besides, it adds to the cost. It is therefore an excellent plan to make use of the kind of fish that is most plentiful, as such practice will insure both better quality and a lower market price.

As is well known, fish is an extremely perishable food. Therefore, when it is caught in quantities too great to be used at one time, it is preserved in various ways. The preservation methods that have proved to be the most satisfactory are canning, salting and drying, smoking, and preserving in various kinds of brine and pickle.

As such methods are usually carried out in the locality where the fish is caught, many varieties of fish can be conveniently stored for long periods of time and so distributed as to meet the requirements of the consumer. This plan enables persons far removed from the Source of supply to procure fish frequently.

In general, the composition of fish is similar to that of meat, for both of them are high-protein foods. However, some varieties of fish contain large quantities of fat and others contain very little of this substance, so the food value of the different kinds varies greatly. As in the case of meat, fish is lacking in carbohydrate.

Because of the close similarity between these two foods, fish is a very desirable substitute for meat. In fact, fish is in some respects a better food than meat, but it cannot be used so continuously as meat without becoming monotonous; that is to say, a person will grow tired of fish much more quickly than of most meats.

The similarity between the composition of fish and that of meat has much to do with regulating the price of these protein foods, which, are the highest priced foods on the market.

How about a heady minestrone brimming with bright zucchini and carrots, green beans and butternut squash, fragrant garlic and onion, and slivers of plump cabbage leaves for dinner?

Or perhaps you would prefer a simple pizza slathered with ruby-red tomato sauce and flecked with fresh basil? Maybe artichoke hearts and tomatoes stuffed with minced onions, cilantro, and a rainbow of chopped bell peppers, Moroccan-style, are more your speed. Chilled tomato and pepper gazpacho, anyone? A Greek eggplant salad with red bell peppers, tomatoes, and wild marjoram?

Or maybe just a simple antipasto featuring grilled vegetables, marinated olives, and ratatouille?

Fresh and plentiful in the Mediterranean region, vegetables and herbs give traditional Mediterranean cuisine much of its character and flavor, not to mention its beauty and vibrant color.

The traditional Mediterranean diet is naturally heavy on vegetables-not surprising, considering the garden-friendly Mediterranean climate. Traditionally, many people in the Mediterranean made their living farming the land. Others simply grew food to feed their own families.

What would classic Mediterranean cuisine be without vegetables? From eggplant Parmesan and tomatoes Provençal to stuffed vine leaves and spinach-cheese pie, vegetables provide the people of the Mediterranean with variety, color, and flavor without the high cost of meat-based meals. But vegetables, it seems, do much more than provide low-cost meals for people eating them in great quantities in the Mediterranean.

Many of the health benefits of the traditional Mediterranean diet are undoubtedly due to the high proportion of fresh vegetables.

Many studies have examined the protective effect of vegetable consumption against certain chronic diseases. Some have uncovered an inverse association between vegetable and fruit consumption and the risk of many types of cancers, especially cancers of the upper respiratory and digestive tracts, lungs, stomach, pancreas, and cervix, as well as colorectal and ovarian cancers.

Could vegetable consumption in the Mediterranean be linked to low chronic disease rates? Evidence mounts to support this theory, even when the evidence doesn’t directly involve the Mediterranean. Not too long ago, researchers Kristi Steinmetz, Ph.D., R.D., and John Potter, M.D., Ph.D., compiled more than two hundred population and animal studies that looked at plant food consumption and cancer rates.

Indeed, there appears to be a strong relationship between plant food consumption and cancer rates. The researchers could only speculate that cancer can be a disease resulting from a diet devoid of sufficient amounts of plant foods.

Human bodies, it seems, are better able to maintain and even regain their health when plant foods make up the majority of calories in the diet. But that is no surprise to people studying the cuisine and health status of people living in the Mediterranean.

High vegetable consumption seems to have a profound effect on the occurrence of other chronic diseases, not just cancer. The risk of heart disease, arthritis, macular degeneration (age-associated loss of sight due to gradual degeneration of the macula, a part of the retina), age-related cognitive decline (such as Alzheimer’s disease and other forms of dementia), and other age-related health problems may all be reduced as vegetable consumption increases.

In addition to decreasing the risk of chronic diseases, research suggests that once chronic disease is present, certain components in vegetables may slow or even reverse the progress of the disease.

This process occurs perhaps by offering a boost to the immune system, as well as assisting in the fight against cell-damaging free radicals (more on free radicals later in this chapter).

In short, research on many fronts strongly suggests that a plant-centered diet rich in vegetables, as well as fruits and whole grains, may add both quality and quantity to your years

Scallops have firm, ivory-colored meat that can be divine if not overcooked. The flavor is sweet, nutty and delicate. They are readily available in seafood markets, but they must be absolutely fresh to be good. Everything between the two shells is edible, although in North America people opt for the single large adductor muscle only.

Unlike clam shells, the two halves of a scallop shell don’t completely close. They dehydrate quickly after harvesting and die if the fishermen don’t keep them in optimum environment. Because they are so perishable, processors often clean scallops on board the fishing vessel and keep them on ice. They are not as easily available for harvesting as shrimp.

The fishermen must catch enough to make it worthwhile to bring them into port, so those unfortunate ones they caught early may be shivering quite a while on ice before they haul the last ones in.

Storing scallops in fresh water improves the all-important appearance for marketability. Unfortunately for the consumer, this also increases weight and dilutes flavor.

Individually quick-frozen scallops retain their freshness, flavor and moisture well, and you often get a better buy and quality than fresh ones when you cannot validate just how fresh is fresh.

Distributors usually soak scallops destined to sell as fresh in a chemical (sodium tripolyphosphate) to retain moisture and improve appearance. They may look great but be wary-the chemical alters the flavor and you might think of wandering over to the frozen counter instead.

Stores commonly sell two major species of scallops, the small and more delicately flavored bay scallops and the larger, more abundant and nearly as good sea scallops, which are much cheaper. Tiny calico scallops from Florida are very uncommon. They resemble bay scallops but supposedly don’t have as good a flavor.

The scallops at the market are pure meat, you only lose the liquid it releases on cooking. Count on 4 to 5 ounces (110 to 140 g) per person.

Shrimp is without doubt our most popular shellfish and among the most popular of all seafood. With its firm meat (when not overcooked) and delicate, distinctive but not overpowering flavor, even diners who never choose seafood from a menu may order shrimp (provided there’s some juicy red meat on the plate next to the shrimp).

A dozen different species of commercially important shrimp grow in various parts of the world. With modern air transportation, we have access to all of them. Flavor has nothing to do with size, but restaurants prefer the large shrimp, because they are easier and faster to shell and look very showy on the plate.

Diners are also willing to pay extra for colossal and jumbo sizes. Sizes vary tremendously. Really tiny shrimp weigh less than one-tenth of an ounce (3 g) each (the weight of a clove of garlic), while the giant species weigh in at about half a pound (225 g), too much for one serving.

A significant amount of imported shrimp is now coming from Asian shrimp farms, where they harvest and immediately flash freeze them, then ship by air all over the world. Shrimp are so perishable that they must freeze them immediately after they leave the water. If the shrimp you brought home from the store turns out not very good, blame it on the handling somewhere between the water and your plate. (Or blame the cook.)

It is the underpaid retail store worker that knows the least about handling and storing to preserve flavor. Your best bet is to buy shrimp frozen, if you can find it packaged in the right quantity, and defrost it yourself. (See suggestions on storing later in this chapter.)

Retailers generally buy shrimp in four-pound boxes, that are only occasionally displayed, but you can request a full frozen box. Asian markets always have them in the freezer case. The fresh-looking shrimp on display at the fish counter are not fresh-the clerk defrosted them just a few hours before you arrived. Usually the only way you can buy fresh, never-frozen shrimp is from fishing boats just pulling in.

Don’t ever buy pre-cooked shrimp. Cooking shrimp is almost as easy as cooking potatoes, and you can do a far better job than the supermarket’s underpaid cook in the back.

Apart from breastmilk, no single food contains all the essential nutrients the body needs to be healthy and function efficiently. The nutritional value of a person’s diet depends on the overall balance of foods that is eaten over a period of time, as well as on the needs of the individual. A healthy diet is likely to include a large number or variety of foods, from each of the food groups, as this allows us to get all the nutrients that we need.

We need energy to live and this is provided by the carbohydrate, protein and fat in our diets. But the balance between these nutrients must be right for us to remain healthy. Getting the right amounts of vitamins, minerals, dietary fibre and water is also important for health.

So what becomes as important as the type of foods we eat, is the amount and frequency that we include different foods in our diet. All foods can be part of a healthy diet, so you don’t have to give up the foods that are a real treat, as the key message is that it is the overall balance of foods that is important for health.

The food groups

We can think of all foods as belonging to one of five different food groups:

• Bread, rice, potatoes, pasta and other starchy foods
• Fruit and vegetables
• Milk and dairy foods
• Meat, fish, eggs, beans and other non-dairy sources of protein
• Foods and drinks high in fat and/or sugar.

We will look at these food groups in more detail on the following pages, but let’s first think about the proportions of these food groups in our diet.

Our diets should be based on bread, rice, potatoes, pasta and other starchy foods and rich in fruit and vegetables. A variety of foods from these two groups should make up two-thirds of the food we eat. Most of the remaining third of the diet should be made up of milk and dairy foods, meat, fish, eggs, beans and other non-dairy sources of protein, with limited amounts of foods and drinks high in fat and/or sugar.

It might be helpful for you to think of your diet as a big plate, with sections representing the different food groups. This is the healthy eating model that we use in the UK to describe a healthy varied diet and it is called the eatwell plate.

You should aim to achieve this balance every day, although it is not necessary to achieve it at every meal.

This guide is appropriate for most people over the age of two years, including: vegetarians; people of all ethnic origins; people who are a healthy weight for their height as well as those who are overweight; and pregnant women. People under medical supervision or with special dietary requirements may want to check with their doctor if this general description of healthy eating applies to them.

Children under the age of two years have high energy needs compared to their size and capacity for food so some of the foods (especially those low in fat or high in fibre) included on the eatwell plate are not suitable for them. But between the ages of two and five years, children can make a gradual transition towards the type of diet depicted in the eatwell plate.

For most healthy people, eating a healthy varied diet will provide all the vitamins and minerals the body needs. There are certain times in our lives when we may benefit from taking supplements, e.g. when you are thinking about having a baby or when you get older and you need to take a vitamin D supplement. But you should remember that supplements cannot replace a healthy diet.

Here are two easy examples to help you see that by making very simple changes to your diet, you can easily achieve the right proportions of different food groups within a meal.

Pizza:

Pizza can contain ingredients from the four main food groups:

• A dough base – from the  bread, rice, potatoes, pasta and other starchy foods group
• Tomato puree and other vegetables such as mushrooms, sweetcorn and peppers – from the fruit and vegetable group
• A moderate amount of cheese, or low fat cheese - from the milk and dairy foods group
• A moderate amount of ham or tuna - from the meat, fish, eggs, beans and other non-dairy sources of protein group.

Bacon sandwich:

A bacon sandwich can contain ingredients from three main food groups:

• Two slices of thick cut wholemeal bread – from the  bread, rice, potatoes, pasta and other starchy foods group
• Lean, grilled bacon – from the meat, fish, eggs, beans and other non-dairy sources of protein group
• The sandwich can be filled with plenty of lettuce and tomato and served with a glass of pure fruit juice or a piece of fruit – from the fruit and vegetable group
• If served with a glass of low fat milk, all four groups would be met.

In 1930, with the discovery of vitamins, scientists have understood what had happened and so the miller men began adding B vitamins to refined grain. So the obvious deficiencies have been corrected. More recently, scientists have recognized that many of our diets contain not enough folic acid, so in 1996 the public health authorities have imposed those from the milling industry to add folic acid to flour. But it will take a long time until the science will understand that this strategy of addition for the “wonder bread”, so as it was called by a nutritionist, will not resolve all issues generated from the refining of grain. Diseases caused by deficiencies are easier to follow and to be treated (the successful medicine in their treatment is an important element for the nutrition prestige) rather than chronic diseases and found that the refinement of carbohydrate is involved in the appearance of some chronic diseases- like diabetes, heart disease and certain types of cancers.

The refined grain story is a parable about the reductionist science boundaries which are applied to something so complex as food. For several years, nutritionists know that a food rich in whole grains reduces the risk of diabetes, heart disease and cancer. (The statement remains valid even beyond the indication that people who eat more whole grains probably have a healthier lifestyle and other point of view) Different nutritionists have attributed the benefits of whole grains to different nutrients: fiber of bran, folic acid and other vitamin B from the germ, antioxidants and various minerals. In 2003, “American Journal of Clinical Nutrition” published a non-reductionist study which demonstrates that benefits of whole grains can not be attributed to a single nutrient. The usual reductionist analysis of isolated nutriments could not explain the health improvement of whole grains consumers.

The epidemiologists David R. Jacobs and Lyn M. Steffen from the University of Minnesota has reread previous research and discovered ample evidence of the fact that a rich in whole grains diet reduces mortality which has different causes. Surprising was the fact that, after adjusting the levels of fibers, vitamin E, folic acid, fitic acid, iron, zinc, magnesium and manganese in food (all the benefits that we know about are found in whole grains) it has been discovered an additional benefit of consumption of whole grains, which couldn’t be attributed to any single nutrient nor their totality. So, subjects receiving the same amount of the listed nutrients, but from other sources were not as healthy as those who ate whole grains, “the analysis suggests that another element from the whole grains protects against death”. The authors concluded, somehow vague, but suggestive that “the various grains and their component act synergistically” and they have suggested to their colleagues to take into account the concept of “food synergy”. So here is an argument for a revolutionary idée in relation to the nutritional standards: it could happen that a whole product is much more than the amount of nutrients that it is made.

It is no need to tell you that the proposal was not enthusiastically received by the food industry and this thing is probably not happening anytime soon. Even while I write, Coca-Cola launches drinks full of vitamins, there is the concept of “wonder bread” for industrial food products in their ultimate state (wonder drink?). Since ever there have been invested large amounts of money for processed food and not in whole food marketing and probably the industry investment in a reductionist approach to nutrition is just one. The problem is that there is something in us that love carbs, and that something is the human brain. Human brain keens on to carbs that are reduced to their essence power, which is pure glucose. Once the industry discovered a way to transform the seeds of cereals in the chemical equivalent of sugar, there was no going back.

From this point of view, the refinement of whole food means not only an invention of new ways to make products more resistant and more portable, but also to focus their energy and in a way to accelerate them. The major leap in terms of acceleration was made around 1870, when in Europe were introduced the rolls (iron, steel or porcelain) used for grinding grain. Perhaps more than any other technology, this, which in 1880 replaced the millstones throughout Europe and America, marked the beginning of our food industrialization -reducing it to its chemical essence and accelerating its uptake. Refined flour is the first product of fast food.

Before the millstone revolution, wheat was grounded between two stone wheels and white flour could not be a perfect white because the millstones were removing the bran from the wheat grain (and therefore most of the fiber), but could not remove the germ or embryo that contains essential oils rich in nutrients. The stone mills were only crushing and releasing germ oil. The effect was the gray-yellow shade of the obtained flour (the yellow color is given by carotene) also the shelf-life was shorter because, in contact with air, oil, and rust quickly, that means it grows rancid. People saw and smelled these things and were not satisfied. But what their senses were not perceived was that in the seeds were the most valuable flour nutrients, including most of the proteins, folic acid and other B vitamins, carotenes and other antioxidants and omega-3 fatty acids which quickly grown rancid.

The insert of rollers which could remove the germ by grinding only the endosperm (the starch and protein package from the seeds) has resolved the issue of conservation and color. Now, almost everyone could afford to buy immaculate white flour, which could now be preserved for several months. There was no need for each city to have its own mill, because from that point flour could be transported for long distances. (In addition, it can be ground throughout the year by large companies in big cities: heavy stone mills based on hydraulic power depended on watercourses; the new shafts could be maneuvered whenever and wherever steam engines) And so, one of the basis food product from the Western diets has escaped the space and time limitations, it was sold by appearance and not on the criterion of nutritional value. From this perspective, white flour was one of the first modern industrial food products.

The problem was that beautiful white powder was null or almost null in terms of nutrition. The same was now in the case of corn flour and white rice, whose refining (i.e. removal of the most nutritious parts) was introduced around the same period. In all regions where there were introduced on a large scale, the new refining technologies appeared in a short time, devastating epidemics of beriberi and pellagra. Both diseases are caused by vitamin B deficiencies which were contained in seed. But probably because ot the sudden disappearance of other micro-nutrients from bread, and also the omega-3 fatty acids, affect health, especially that of poor townspeople in Europe, for whom bread was a fundamental food product.

What would happen if we begin to consider food is less a thing and more a relationship? In nature, things have always been like this: eating meant in fact interacting whit species in the systems that we call food chains or tropic networks, which include everything up to the soils. Species co-evolved with the other species that eat them and very often, among them develops a relationship of interdependence: I’ll feed you, if you spread my genes.

Following an evolutionary process of mutual adaptation, the apple or the pumpkin turns into a nutritious and delicious food product for certain animals. Over time and through processes of trial and failure, the plant becomes tastier (and often more visible) to answer the needs and desires of the animal, and so that the animal can develop various digestive tools (eg, enzymes) needed to exploit the plant as good as possible.

Thus, at first, the cow milk was not a nutritious product for people: in fact, it even harms them that until the people who lived around cows developed in adulthood the ability to digest milk. The gene responsible for producing lactase, the enzyme that make the digestion of milk possible, was disabled by humans shortly after medical ablation, but now five thousand years, people have suffered from a mutation where the gene which remains active throughout life, the mutation that quickly spread through a population of pastors in north-central Europe. Why? Because people which suffered this mutation have access to a new extreme nutritious food source and therefore they could multiply more easily than those who had not undergone the mutation that we are talking about. This adaptation was good for those who consume milk but also for cows that have multiplied and expanded their habitat (and have improved their health status) all because of this new symbiotic relationships.

Among other things, health status is determined by the type of relationships within a food chain extreme varied relation in the human case which is an omnivorous. So, when a link from the food chain health is affected, this can be passed on to all other living creatures that make up that food chain. If the soil is sick or suffering from certain deficiencies so will be the gras growing on it and the cows grazing grass and the people who drink their milk. This is what Weston Price and Sir Howard was thinking when they were trying to establish a connection between these apparent distant spheres: soil and human health. We can not separate our own health from the entire health chain.

One of the most active voices of the prewar period was Weston A. Price, a dentist of Canadian origin who leaned on one of those questions of common sense, which today can not even ask us. Now, like heart disease, chronic dental problems are a part of our lives.

But if you think about it, it is strange that everyone needs a dentist and that so many people need braces, channel interference, the wisdom tooth extraction and other routine procedures necessary to maintain modern oral hygiene. The need of many remedial interventions for just one body part that is involved in the feeding activity, activity that is essential for our survival, reflects a defect in our design, a kind of omission of the natural selection? It is unlikely.

But what did Price found out? First, he found out that populations that eat traditionally have no need for a dentist.(Well, almost: the teeth of the “strong highlanders” in Switzerland, which have never seen a toothbrush, were covered with a greenish-filing but Price found that, below this layer, the teeth were well formed and had no cavity). Whenever he discovered a primitive population that hasn’t yet contact with “alimentary substitutes of modern trade” - as refined flour, sugar, vegetable oil, canned or preserved food trough chemical ways- revealed very few or none signs of modern degeneration - like chronic diseases, dental caries and dental arches with malformations. These problems were caused either by a certain element of Western diet either a certain deficiency.

Wherever Price went, he took pictures of the teeth of the populations that he met and took samples from their food and sends these to Cleveland for analysis so that he could determine the content of macro-nutrients and vitamins. He found out that the indigenous diets were much richer in vitamins A and D than the modern U.S. - in average about ten times higher. This was due in a large part to the fact that, as is it was noted in 1930, that by processing food, it loses nutrients, especially vitamins. Trade food are thought to be stored and transported over long distances and the only way that they can become more resilient and less vulnerable to pests is to remove some of the containing nutrients. In general, the calories are much easier to transport- in form of refined cereals or sugar-only nutrients that can alter or attract bacteria, insects and rodents, all extremely interested in these nutrients. (Even more than us, apparently.)

Price concluded that the modern civilization did sacrifice mostly the quality of the food in favor of the quantity and the length of the shelf-life.
