According to dietary guidelines, is 5% of calories from protein sufficient for health?

The recommendation for protein intake in the diet is significantly higher than 5% of total calories. Generally, dietary guidelines suggest that protein should make up about 10% to 35% of total daily calorie intake for the average adult. This range helps support various bodily functions, including muscle repair, immune function, and the production of enzymes and hormones.

A protein intake level of 5% of total calories falls below the minimum recommended amount and would likely lead to deficiencies in essential amino acids, which are crucial for health. Insufficient protein can have a variety of negative health impacts, particularly affecting muscle mass and overall energy levels. Inadequate protein intake may also impair recovery from illness and stress and lead to longer-term health issues.

While individual protein requirements do vary based on factors like activity level, age, and health status, the general consensus is that 5% is inadequate for maintaining proper health for most individuals, including athletes, who typically require more protein to support their increased activity levels and muscle maintenance.
