Understanding The Gluten-Free Diet And The Lesser-Known Downsides

Nutritional Deficiencies

Patients who follow a gluten-free diet may be at risk of nutritional deficiencies. Unlike most foods that contain gluten, many gluten-free foods are not fortified with vitamins and minerals. Thus, individuals who follow gluten-free diets for a prolonged period could be getting insufficient amounts of nutrients like calcium, riboflavin, iron, niacin, folate, and thiamine. If nutritional deficiencies develop, patients could experience symptoms such as exhaustion, depression, anemia, confusion, nausea, and abdominal cramps. Those considering a gluten-free diet may want to have their nutrient levels tested both before and during the diet plan. If levels are low, doctors may need to prescribe high-dose supplements, and some patients may be asked to take over-the-counter supplements. Individuals who notice exhaustion, mood changes, or any other concerning symptoms while on a gluten-free diet should mention these to their doctor.
