Micronutrients & recovery

Gluten-free diets are not nutritionally superior to gluten-containing diets and are often inferior in key nutrients including fiber, folate, protein, magnesium, potassium, and vitamin E, while providing higher energy and fat intake.

If you are not celiac, switching to a gluten-free diet is unlikely to improve your nutrition and may actually reduce your intake of fiber, protein, and key vitamins like folate and magnesium. Focus on whole, unprocessed foods regardless of gluten content rather than seeking out 'gluten-free' labeled products which may be nutritionally inferior.
