Several studies in medical journals have shown that the decrease in biodiversity is associated with a series of problems for human health.
These studies concern the effect of diet on the composition and diversity of the microbiota. Remember that the microbiota - also known as intestinal flora - is the complex of bacteria, viruses, fungi, yeasts and protozoa that lives in our intestine and that not only our physical health but also our mental health depends on its composition and diversity.
In particular, our immune system depends on the composition and diversity of the microbiota and therefore the possibility or not of contracting inflammatory-based diseases, such as irritable bowel, ulcerative colitis, cardiovascular disorders, various liver diseases and many types of cancer. With regard to mental health, it has been demonstrated that the microbiota regulates both the brain and behavior, and influences anxiety, depression and, in general, quality of life.
Given the important role of the microbiota on the one hand and the fact that it is so strongly and rapidly influenced by diet on the other, it is understandable that there have been many studies on the effect of various diets (Western, omnivorous, Mediterranean, vegetarian, vegan, etc.) on its composition and diversity. The general recommendation of these studies is that in order to have a healthy microbiota, it is necessary to follow a diet that is as diverse and varied as possible. However, following this recommendation is a problem since behind our food there is an agriculture based on uniformity: three crops, wheat, corn and rice, provide us with 50% of our energy, and 12 plant species together with five animals represent 75% of our food. And it is an even more complicated problem in Italy since in our diet there are often bread and pasta, produced precisely from one of those crops in which genetic improvement has reduced genetic diversity the most: a few genetically uniform varieties and all more or less related to each other and mostly coming from industrial agriculture.
Bread, biscuits, and crackers produced with Aleppo Mixed wheat flour, and pasta made with durum wheat Aleppo Mixture semolina, both grown organically, offer a solution to the problem because in that bread, in those cookies, and in those crackers there are about 2000 different types of common wheat, and in that pasta dish about 700 different types of wheat.
