2. Appetite Loss
Do foods you normally enjoy suddenly taste lacklustre? It could be due to a lack of zinc. Numerous studies link diminished ability to taste and smell foods (dysgeusia and anosmia) with a zinc deficiency. “You can have symptoms that mimic anorexia,” says Boyan Hadjiev, MD, certified in internal medicine and allergy and immunology to Reader’s Digest. “You can have symptoms that affect your mental function, including you learn and how you perceive pleasure,” which might also play into appetite loss.
Luckily there is research that shows taking zinc orally can improve the symptoms of people who have taste disorders, “since it may help stimulate a region in your brain that controls your food intake,” explains Prevention. Another strange factor of this is that it seems to be more prominent in people who are over the age of 60. These adults are already at a higher risk for having a zinc deficiency and might be taking other medications that affect their ability to taste.
