Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A healthy person eats a very high-protein diet. What effect will this have on their urine?
A
A It will contain amino acids.
B
B It will contain glucose.
C
C It will contain more urea.
D
D It will contain more water.
Explanation: 

Detailed explanation-1: -When the proteins are digested, urea is formed as a byproduct which the body does not need. Hence, it is eliminated through the urine. Therefore, if a person eats a very high protein diet, his urine will contain more urea.

Detailed explanation-2: -In the previous studies, consumption of a large protein-rich diet has been associated with increased urinary urea excretion [14, 21], increased blood urea levels [17], a period of glomerular hyper-filtration [20, 21], and increased urinary sodium excretion [20, 21].

Detailed explanation-3: -A high-protein diet may worsen how well a kidney works in people with kidney disease. This can happen because the body may not be able to get rid of all the waste products of protein that’s broken down.

Detailed explanation-4: -A high-protein diet typically contains large quantities of purines. However, such diets may have an uricosuric effect (i.e., increase excretion of uric acid in urine), resulting in lower serum acid levels (11, 12).

Detailed explanation-5: -It helps to build and repair muscle, organs, and bones. High-protein diets have also been shown to be helpful with reducing fat, losing weight, increasing satiety, or a feeling of fullness, and retaining muscle.
