Stronger than DNA, our gut bacteria can predict the onset of serious diseases, such as Parkinson’s and type 2 diabetes, and even mark our response to Covid infection. That is, it can be predicted whether, by taking Coronavirus, we will develop mild or severe symptoms. A very detailed study appeared in the journal Nature explains that the correlation between nutrition and health exists and is bacterial.

Depending on our diet, in fact, we will have a different intestinal flora. That is, friendly bacteria or good bacteria, which strengthen the immune system and metabolism, reducing the risk of serious diseases.

And bacteria that are enemies of health or bad that instead predispose more of our genetic profile to develop certain diseases. Which, so to speak, is good news. It means that by changing our diet we can improve our bacterial flora and therefore our health and our metabolism.

Let’s see the study in detail.

CORRELATION BETWEEN DIET AND HEALTH: THE BACTERIAL THESIS

The study was conducted by the Department of Integrative, Computational and Cellular Biology of the University of Trento and the Department of Nutrition Sciences of King’s College London.
Each of us, the study explains, has a different bacterial flora.

Looking at the diets of more than 1,000 people and analyzing more than 1,200 gut bacteria, however, the researchers noted that there is a correlation between some bacteria, eating habits, and predisposition to disease.

Some of these bacteria have been analyzed for the first time from a scientific point of view.
In particular, it has been seen that a diet rich in antioxidants, from fresh and raw vegetables and fruit, and from foods of animal origin such as oily fish, positively modify the bacterial flora.

For example the bacteria Prevotella copri and  Blastocystis spp. they are friendly bacteria. These improve the sugar metabolism and therefore the blood sugar of the individual.

Most importantly, the researchers found that bacteria are more influential than individual metabolic markers.
This means that a person who is not familiar with certain diseases may risk developing them if they have a “bad” intestinal flora.
