High Protein diets, calcium and Kidneys.

Precautions while on a high protein diet.

• Protein, water and calcium: When on a high protein diet, take care of the water input as high protein diet is known to cause increase concentration of calcium in urine. 
• Habitual excess protein intake is a significant risk factor for calcium loss via the kidneys. Calcium excretion also accompanied with daily urinary excretion of urea. The calcium excretion with animal protein intake was found to be significantly positive in both sexes and in each age group whereas that with plant protein was not. Findings suggest that regular use of excess protein in diets may augment calcium excretion in the urine, at least in the elderly.
• Sports persons especially bodybuilders control their water input when they are near the competition date, and they increase their protein intake at the same time, this may lead to excess excretion of calcium.
• Plenty of water, regular physical activity (30 minutes walking, more than 5 days a week) and monitoring kidney profile should prevent any adverse effects.
