Protein is an important nutrient that makes up a healthy diet. Proteins are composed of amino acids, building blocks that maintain tissue and cell functions in your body, reports the University of Michigan Health System. After ingesting a protein packed meal, your digestive system breaks it down and converts it into cell food. Although protein is beneficial for your body, consuming excessive amounts can produce negative health risks.
Kidney Strain
Excessive protein consumption can eventually lead to kidney damage, reports the Harvard School of Public Health. The kidneys primary role is to filter blood in your body. Glomeruli, specialized cells in the kidneys, filter your bloodstream to keep minerals, proteins and other nutrients in your body while allowing toxins, excess water and salts to enter the urine for excretion. High protein consumption can contribute to a substantial increase in protein components, which increases strain on the kidneys as blood is filtered. As you age, this can also contribute to diminished kidney functions.
Dehydration
High protein in your blood can cause dehydration, especially if carbohydrates are replaced with protein-rich foods in your daily diet, according to Ohio State University. This occurs due to the hydration level that occurs in carbohydrates and proteins on a molecular level. Carbohydrates sources, such as starch, are heavily hydrated with water molecules. Proteins tend to be mildly hydrated. Consuming a diet poor in carbohydrates but rich in proteins means you are are consuming decreased amounts of water from your regular diet. You may become dehydrated over time unless you supplement your water intake with extra water. You can prevent dehydration by maintaining a healthy balance of carbohydrates and proteins while drinking fluids throughout the day.
Calcium Loss
Excess protein in your blood can lead to calcium excretion from your body, the University of Michigan Health System notes. Calcium makes up a component of the teeth and bones, aids in nerve signal transmission and plays a role in tissue signaling. Calcium excretion due to high protein in the blood can contribute to progressive calcium loss in your bones. High protein, especially from animal sources, have been linked to osteoporosis, a disease of the bones. Prevent unnecessary calcium excretion by restricting your protein consumption to 0.8 g per kg of body weight.
