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.
