Protein diet: that's what you do with your body

The high-protein diet could have adverse health consequences, which was the subject of a new Australian study.

"Science has long known that overeating, especially protein, reduces a person's lifespan, and we now know why," says Professor Christopher Broad of the Institute for Health Research and Development. Medical Research of South Australia (SAHMRI).

The researcher, in fact with his team at the University of Adelaide in Australia, thinks he has found an explanation for this phenomenon: "The rapid treatment of proteins". Their results were published in Current Biology on February 14th.

Animal and vegetable proteins

To reach their conclusions, scientists used worms and fruit-producing insects to study the effects of the diet on the rate of protein synthesis.

These proteins, whether of animal or plant origin, are analyzed by the body in amino acids and used to make new proteins. It's the heart or the core of our cells.

Proteins are essential for the body to fulfill its functions: they help regenerate skin, nails, hair and muscle tissue, defend the body against disease and are essential for growth.

Moderate protein consumption

But if protein is consumed in large quantities, such as in a high-protein diet, for example, protein will have a detrimental effect on health.

"Our team has shown that an increase in nutrient levels speeds up the making of proteins in cells," says Professor Christopher Brod.

The faster the process, the more errors. "

In fact, as the number of proteins in the body increases, the body must "speed up" the production of the new proteins that make up our cells.

The body usually has time to correct manufacturing errors, but this protective mechanism disappears quickly, accumulates defective proteins, causes health problems for the body and reduces life expectancy.

"It sounds like a lot of everyday activities like driving, for example: the faster you drive, the more risk you run," he says.

Australian researchers recommend a more balanced diet, rich in "good" carbohydrates.

They also warn against "bad press, especially with regard to food systems", and point out "the consumption of high-fiber carbohydrates, such as those found in fruits and vegetables, cereals and unprocessed seeds, which offer all the best health benefits. "

In this regard, the researchers recommend the "Mediterranean diet known for its benefits that increase life expectancy".
