This condition significantly increases the risk of stroke e cardiac arrests. You can read the results in the scientific journal Nature Metabolism.

At least a quarter of adults get more than a fifth of their daily calories from protein. Research returns to talk about the need to follow a balanced diet with carbohydrates, fats, fibre, vitamins and mineral salts.

Link between proteins and the heart: how much should you eat to stay healthy?

They are more or less equivalent to two chicken breast fillets or one and a half salmon fillets. A woman weighing 60 kilos, 49.8.

Research on the link between proteins and the heart

The researchers fed protein meals to 23 people by taking blood samples immediately before and three hours after eating. Each of them had fasted for the previous twelve hours.

The results showed that protein consumption causes an increase in leucinean amino acid, and of another molecule that stimulates the immune system. This molecule activates macrophages that increase inflammation.

The limitations of the study

Some experts not involved in the research argue that relying on a single meal is not enough to develop a theory. However, a diet high in protein can certainly trigger an inflammatory response that contributes to the risk of cardiovascular disease, especially if it involves animal proteins.
