Many people believe that a high-protein diet can have negative health effects, such as osteoporosis or kidney damage. However, research shows that these concerns are mostly unfounded. Protein is a fundamental building block of life and is crucial for the structure and function of the body. A moderately high-protein diet has many health benefits, including increased bone density, reduced risk of fractures, increased lean mass, and weight loss promotion. For kidney health, a high-protein intake does not negatively affect kidney function in healthy individuals and may help manage high blood pressure and diabetes. In summary, a high-protein diet is safe for most people and has many health benefits.
