Question

Todd weighs 170 lb (77 kg) and consumes approximately 190 gm of protein each day. His current protein intake may result in ____________.
a) iron deficiency

b) diabetes

c) excess fiber intake

d) loss of calcium

Answer 1

Answer:

d) loss of calcium

Explanation:

DIet which is high in protein and low in fruits and vegetables, generates a large amount of acid, mainly as sulfates and phosphates. The kidneys respond to this dietary acid challenge with net acid excretion, as well as ammonium and titratable acid excretion. Concurrently, the skeleton supplies buffer by active resorption of bone. Indeed, calciuria is directly related to net acid excretion. Different food proteins differ greatly in their potential acid load, and therefore in their acidogenic effect. A diet high in acid-ash proteins causes excessive calcium loss because of its acidogenic content. The addition of exogenous buffers, as chemical salts or as fruits and vegetables, to a high protein diet results in a less acid urine, a reduction in net acid excretion, reduced ammonium and titratable acid excretion, and decreased calciuria. Bone resorption may be halted, and bone accretion may actually occur. Alkali buffers, whether chemical salts or dietary fruits and vegetables high in potassium, reverse acid-induced obligatory urinary calcium loss. We conclude that excessive dietary protein from foods with high potential renal acid load adversely affects bone, unless buffered by the consumption of alkali-rich foods or supplements.

Answer 2

Answer:

The correct answer is option D. loss of calcium.

Explanation:

The appropriate protein intake in an average person is 0.8 gm per kg of body weight. By calculating it is clear that he is taking a very high amount of protein that can lead to many negative impacts and one of them is the loss of calcium.

Studies have suggested that protein intake in high amounts can lead to an increase in urinary excretion of calcium.  

Thus, the correct answer is option D. loss calcium.
