I don’t know how, but the transition from news to the way it is then proposed to us is sometimes embarrassing: when we often hear about “bad science”, in Italian “bad science” or better pseudoscience, it does not refer only to studies involving samples that are too low in the population to be generalized or commonplaces that have no scientific basis except in a distant memory, but also to the whole process of simplification with which a scientific study is then digested and reported and finally understood by readers.
In the simplifications concerning nutrition, for example, this becomes a problem. What makes you lose weight? What makes you fat? How does the metabolism work? Do calories exist or not? Is this food bad for you? Is this good for you?In an attempt to explain and make certain things understandable to people, the news is often recomposed and digested to create simply the anti-news.
An example of what I am saying is there for all to see.

WHO says eating red meat may be linked to a higher risk of cancer, but experts aren’t sure; red meats, as well as coffee, pickles, fried foods and so on. Now, from this to saying that “meat hurts” we pass. Four kilos of cream puffs are also bad. Anyone would understand that in medio stat virtus , and that the key to staying healthy is moderation.
But no. Everywhere we read that meat “causes” tumors. Have the experts ever said this? NO. But people are convinced of it.
Where do you get these beliefs from? By word of mouth?

Similarly, in the review of this book,  The Myth of the Diet by Tim Spector , we find many things that we already knew about what makes you lose weight and what above all does not make you lose weight, and that this blog alone has covered at least in a hundred articles: that people respond subjectively to diets, just as they respond subjectively to physical activity. This is because of our bacterial flora, which, well before Tim Spector, epidemiologist, many other doctors, including dieticians, had investigated. In Italy, I think Professor Pier Luigi Rossi has been talking about it for years now. I myself will have written, without exaggerating, about fifty articles on bacterial flora, reporting as many studies. Coming out now saying that all diets do not work, that our weight derives in part from genetics, that we can only act on some factors, but not on all, is something said, repeated, known .
