Symptoms of Phenylketonuria (PKU)may Be Minimized or Suppressed by a Diet

Question

Symptoms of phenylketonuria (PKU)may be minimized or suppressed by a diet low in  
A) serine.
B) glycine.
C) phenylalanine.
D) proline.
E) glutamic acid.

Accepted Answer

PKU is a genetic disorder that hinders the body's ability to break down and process phenylalanine, an amino acid found in protein-containing foods. If left untreated, the accumulation of phenylalanine may result in brain damage, intellectual disability, and other neurological problems. Thus, a low-phenylalanine diet (restricted protein intake) is recommended for individuals with PKU to prevent the progression of symptoms. Choices A, B, D, and E are not directly associated with PKU symptoms.
