Gluten -free flour is a flour that does not contain gluten, a protein present in wheat, barley and rye. It is commonly used by people with celiac disease or gluten intolerance because it allows them to prepare foods without risk of adverse reactions. There are several types of gluten -free flour available on the market, each with its own characteristics and uses. Rice flour, corn flour, chestnut flour and pea flour are some examples of gluten -free flours commonly used. Gluten -free flour is rich in protein, dietary fiber and nutrients such as iron, zinc and B vitamins. It is also a source of complex carbohydrates and minerals, such as calcium and potassium. Due to its high fiber and protein content, gluten -free flour is considered a healthy and nutritious diet.
