Then, we have the reader whose daughter is gluten-intolerant. However she is worried that eliminating gluten from her diet will deprive her child of the necessary amino acids to build up her immune system and fight infections. What would make good gluten replacements? Well, she wouldn’t have to look far for gluten-free (GF) foods. Virtually all health food shops stock a good range of GF foods (most of which are actually quite tasty) and there is little problem to find it down our local Tesco’s. GF foods that are especially high in vitamins and minerals arequinoa, amaranth and arrowroot, says one reader. Replace the missing infection-fighting nutrients in gluten with other supplements such as antioxidant vitamins or herbal extracts such as magnolia extract and French maritime pine bark.
