What Does Excess Protein in the Diet Do?

Introduction

Protein is an important nutrient needed for the body to operate and survive. Protein contributes to healing, building body tissues, creating hormones and enzymes and even helping to strengthen your immune system. Unfortunately, when protein is not eaten in moderation, the excess protein consumption can lead to possible health problems.

Kidneys and Liver

Since excess protein cannot be stored in the body, all protein has to be broken down and either used or sent through the kidneys and liver to be excreted from the body. For healthy adults, this is usually not a problem; however, too much protein in those with compromised livers or kidneys can put too much stress on these organs when trying to work through the extra waste created by the excess protein. According to the Mayo Clinic, excess protein may also contribute to the production of kidney stones.

Bones

Eating an excess of protein can have a devastating impact on the bones if not balanced with an increase in calcium consumption. When protein is digested, acids are released in the process which neutralize the calcium in your body. Since calcium is a necessary ingredient for many bodily functions, the body compensates by leaching calcium from the bones. This can lead to a calcium deficiency resulting in a weakening of the bones.

Cancer

Although protein in general will not cause cancer, certain types of high-protein foods in excess can. This mostly applies to red meats and processed meats. According to the American Institute for Cancer Research, these two types of food may contribute to an increased risk for colon cancer when not eaten in moderation.
