Excessive protein intake poses several health risks. Consuming high amounts of protein, particularly from animal sources, can strain the kidneys over time, especially for those with pre-existing conditions. It may also lead to nutrient imbalances if protein-rich diets are not balanced with fruits, vegetables, and whole grains. High protein diets can contribute to an increased risk of cardiovascular issues due to saturated fats found in certain protein sources. Furthermore, excessive protein can lead to digestion issues, such as constipation or dehydration. Moderation and balance remain key for overall health.
