PURE study: high-fat diets were better than carbohydrate

What do they have in common? These are hypothesis-forming studies. And this needs to be explained very clearly because they can not change anyone's life. Not at this time.

The PURE study showed some things that we already imagined, as people with higher consumption of fruits and vegetables (400g per day) live longer. Raw vegetables had better performance than cooked (except in Asia, for unknown reasons). Those who exercise more live longer. And a bomb: high-fat diets were better than high-carbohydrate diets. And who traded between the extremes (fat or carbohydrate) had better performance going to fat than coming out of it.

The diet in Brazil is already very rich in fats. And this result does not mean that we should switch carbohydrates to fat, but raises that hypothesis. The best way to prove that this is right would be to get twins and ask one to eat only one fat and one carbohydrate. In the absence of twins, we could look for similar people (same height, same weight, similar functions) and choose which item of the diet we want to test.

About the study of cheeses, also observational: Which cheese is good? How much? Is cottage cheese cheese? Researchers have joined several studies from several countries with several different cheeses and those who ate cheese lived the most. Like the wine in some jobs.

The problem with these studies is that we can not adjust all the variables. Imagine the scene of the cheese. Let's say that those who ate cheese lived on the edge, a high standard of living with access to the best hospitals and doctors and those who did not eat cheese lived in an area of ​​extreme poverty where violence kills more than many wars? In the absence of evidence from randomized trials (the ones that we have been able to get from the start to place similar people, one on one side and their peers on the other), we can accept these as alternatives, but with common sense and criticism. An example is the one for falls. In the journal BMJ (British Medical Journal) an editorial was made explaining that not all the evidence should come from the studies. For example, there are no studies that prove that parachutes work. That's because nobody tried to jump without and with a sufficient number of times so that the statisticians are satisfied. Although absurd, it would technically be true. But good sense prevails that no one can jump off an airplane without it.

This news is great, but before we change our whole way of life, it is worth an individualized analysis of the person, and try as far as possible to use studies that provide the maximum safety and reliability to improve survival (and the quality of life, why not?).
