In the same way as carbohydrates and lipids, proteins contribute to our energy intake. Whether animal or vegetable, proteins play a so -called “structural” role in our organism.
They are essential for the synthesis and renewal of many fabrics: muscles, pharères (nails, hair, hair), bone, skin, tendons, ligaments …
This biological importance partly explains the current craze. Sportsmen and influencers promise attractive benefits: muscle development, reduction in fat, improvement of recovery. Arguments that seduce in a society where physical appearance and performance occupy a central place.
Are our real needs so difficult to cover?
You should know that the recommended daily intake (AJR) is 0.8 to 1 g of protein per kilogram of body weight and per day. This represents for example a consumption of 60 to 75 g per day for a 75 kg person. But ” This contribution can be easily reached thanks to a balanced diet ”, specifies the INSERM.
Indeed “proteins are present in many foods of our daily life, in the form of animal proteins as in chicken meat (100 g contains approximately 22 g of protein), fish (100 g contains approximately 20 g of protein), milk, or even in the form of vegetable proteins as in cereals (wheat, oats) and legumes (lentils, chickpea …). »
Enriched products: not without drawbacks
If protein -enriched foods may seem practical, they often hide faults. Protein bars, for example, certainly contain additional proteins, but also frequently added sugars and various preservatives depending on the brands.
In fact, as the media The Conversation points out, “rich in protein” on a label generally means “highly transformed”. Made industrially, they contain ingredients that cannot be found in a kitchen. However, scientific studies regularly establish links between the consumption of ultra-transformed foods and various health problems, including cardiovascular disease and diabetes.
Another problem with protein -enriched products is that, even if they actually contain additional proteins, some products may lack essential fibers, vitamins and minerals. In summary, protein -enriched products are occasional foods that can help cover protein intake, but they should not be taken for miracle foods or confused with completely healthy foods.
Watch out for excess
Finally, the artificial increase in our protein consumption is not without risks. Regularly exceeding the recommended intake can excessively request the liver, the intestine and the kidneys, responsible for eliminating ammonia produced by the degradation of proteins.
As the INSERM explains, ” Among the undesirable effects which can then be observed : intestinal discomfort and digestive disorders, hyperammonemia (elevation of ammonia in the blood), hyperinsulinemia (elevation of insulin), dehydration, nausea, hepatic and renal lesions, fatigue, headache … ».
