While excess protein intake may impose a metabolic burden on the bones, kidneys, and liver, protein deficiency can wreak havoc on your body. Protein deficiency is seen as a condition called Kwashiorkor in children, and Marasmus in both children and adults. “In Kwashiorkor, children show signs of fluid retention, oedema and fatty liver. In Marasmus, there is extreme emaciation and prolonged negative energy balance leading to fat exhaustion and wasting of muscles. Organs such as heart, liver, lungs and kidneys are compromised in their functions due to the short supply of protein synthesis and more tissue breakdown,” says Karthiyayini Mahadevan, head – wellness and well-being at Columbia Pacific Communities.
