List and describe 2 ways in which too much dietary protein can be harmful.

High protein intake may increase the risk of some health problems. Three health conditions that have received particular attention are heart disease, bone loss, and kidney disease.

High Protein Intake is Associated with High Cholesterol
•   High-protein diets consisting of mainly animal foods are associated with higher blood cholesterol levels. This is likely due to the saturated fat in animal products, which is known to increase blood cholesterol levels and the risk of heart disease.

High Protein Intake Can Increase the Risk for Kidney Disease
•   People who are susceptible to kidney disease, such as those with diabetes mellitus, may benefit from a lower-protein diet. There is no evidence, however, that eating more protein causes kidney disease in healthy people who are not susceptible to this condition. Experts agree that eating no more than 2 grams of protein per kilogram body weight each day is safe for healthy people.
