Hello, I would like to ask about the maximum amount of protein in one serving. I have heard the information that one should never consume more than 35 g of protein in one serving, regardless of a person's constitution. Do you agree with this information? Personally, it seems relatively low to me, especially for some men. If the amount is limited per serving, what is the reason for this? Is it more related to meat due to heavier digestibility and strain on the body, or does this generally apply to plant proteins as well? Thank you for your response.

It is not possible to establish a specific universal threshold; the amount of protein intake is primarily related to body weight, level of physical activity, and an individual's metabolic profile. The fact is that with an increasing amount of protein in one serving, the digestive load also increases. Evaluated indicators commonly address the factor of nitrogen balance, which can be negative (in situations with a lower protein content in meals) or positive (with a higher protein content in the diet). If the nitrogen balance is positive (amino acids contain amino groups, which include nitrogen—the body breaks down nitrogen during protein digestion, and in excess, this balance state occurs), proteoanabolic processes dominate in muscle metabolism, but the excess nitrogen simultaneously burdens the liver.

In the long-term perspective, every person should strive to maintain metabolic balance; hence, monitoring protein intake in relation to health (including the proportion of plant and animal sources) is beneficial. The cited 35 g per serving is an averaged population figure. Individuals with higher body weight (or muscle mass proportion) and physical exertion are capable of handling much higher amounts of protein in one serving without significant issues.
