Is there really the possibility of formulating a diet starting from one’s own DNA?  A genetic diet? I begin by saying that it is practically everyone’s dream, the emblem of the personalization of a personalized diet that cannot be more than that, being our unique genetic heritage.
A way to understand if, for example, there are foods that are particularly good for us, that activate who knows what in our body that makes us deflate, purify the skin, lose pounds like snow that melts in the sun.

Here, this way, this ideal genetic diet that we are all automatically led to believe, does not exist .
You can get it out of your head for now. Are there any margins for which knowing something about one’s DNA can help improve and personalize our diet? Yes, and I indicate here what can be done today thanks to genetics ( source ).

GENETIC DIET: WHAT DOES IT REALLY CONSIST OF?
1) What can a DNA test tell us about which diet is best for us? At the moment, a genetic test can provide us with a series of information which, however, more than concerning weight loss, concerns nutrition in general. Example: how we react to caffeine; how and how much we absorb micronutrients, and in what we tend to have personal deficiencies between vitamins and mineral salts (if for example we are genetically predisposed to malabsorption of calcium or iron); how physical exercise has an impact on our health or not (we know that physical exercise, although it is good for everyone, does not give univocal answers in terms of body recomposition. For example there will be those who tend to hypertrophy, those who have useful features for athletic sports such as running).

2) Can’t a DNA test tell us anything at all about how to lose weight? A DNA test at the moment can give us useful but not fundamental information: it can establish why we have a predisposition for sweet and unsalted foods; it can establish for which diseases we have a genetic predisposition, for example at the cardiovascular level. However, according to José M. Ordovás, head of the nutrition and genomics department of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, the knowledge of a few genes, those analyzed by the test, does not allow today to give more targeted information than the ones I have just listed. In short, it will take years to analyze the more than twenty thousand genes that make up our genomic map.

So no specific advice can be given thanks to today’s DNA tests: nutrigenomics is making great strides, but if you already follow a healthy and balanced diet, doing a genetic test to lose weight is not useful.
