Why a food that is claimed to make a person taller can't do this?

Answer 1

Height is primarily determined by genetics and is largely established during the growth phases of childhood and adolescence. While nutrition plays a role in overall health and growth, no specific food can alter genetic factors or stimulate growth once the growth plates in the bones have closed. Claims that certain foods can make a person taller are often misleading and lack scientific support. Instead, a balanced diet can support healthy growth during developmental years but cannot change height after maturity.
