Excessive protein intake can lead to various health risks, including kidney damage, dehydration, and nutrient deficiencies. High protein diets, particularly from animal sources, may increase the workload on kidneys, especially in individuals with pre-existing kidney conditions. Furthermore, consuming too much protein can lead to unbalanced diets, as it may replace essential carbohydrates and fats, limiting overall nutrient diversity. Long-term excessive protein intake can also contribute to osteoporosis due to potential calcium loss.
