Benefits of Protein

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Protein is a vital nutrient with numerous health benefits, including supporting bone health, enhancing muscle mass and strength, aiding in weight management, and potentially influencing longevity and metabolic health. Adequate protein intake, tailored to individual needs and combined with physical activity, can optimize these benefits. Further research is needed to refine protein intake recommendations to maximize health outcomes across different populations.

Bone Health

Dietary protein plays a crucial role in maintaining bone health. Higher protein intake, especially when combined with adequate calcium, has been shown to reduce bone loss and the risk of hip fractures in older adults. Studies indicate that protein levels above the current Recommended Dietary Allowance (RDA) can be beneficial for bone mineral density (BMD) and may slow the rate of bone loss in individuals with osteoporosis1 3. Protein supplementation can also attenuate age-related decreases in BMD and reduce bone turnover markers1.

Muscle Mass and Strength

Protein is essential for muscle health, particularly in the context of resistance training. Protein supplementation has been shown to enhance muscle mass and strength gains during prolonged resistance-type exercise training in both younger and older populations4 9. Consuming adequate protein at each meal, especially in combination with physical activity, can help delay the onset of sarcopenia and maintain muscle function5. This is particularly important for older adults, who may benefit from a more evenly distributed protein intake throughout the day5.

Weight Management

Higher-protein diets have been associated with successful weight management strategies. They can lead to greater weight loss, fat mass loss, and preservation of lean mass compared to lower-protein diets. These diets also improve cardiometabolic risk factors, such as triglycerides and blood pressure6. The satiety effect of protein can help reduce appetite and energy intake, contributing to better weight control6.

Longevity and Metabolic Health

The impact of protein on longevity and metabolic health is complex. While high protein intake, particularly from animal sources, may be linked to age-related diseases, adequate protein is necessary to prevent malnutrition and conditions like sarcopenia. Balancing protein intake, especially by moderating specific amino acids like methionine and branched-chain amino acids (BCAAs), may offer benefits for longevity and metabolic health10.
