Question

Quizplus · Accepted Answer

Patches of scaly skin and bald spots on the head are symptoms of an essential fatty acid deficiency. Polyunsaturated fats, which include omega-3 and omega-6 fatty acids, are essential for maintaining healthy skin and hair. Adding polyunsaturated fats to Duncan's diet would have resolved the deficiency and eliminated his symptoms. Lipase is an enzyme that breaks down fats and would not have addressed the specific nutritional deficiency that Duncan was experiencing. Calcium citrate and oleic acid are not related to skin or hair health.
