Finding gluten-free ingredients for cooking can be intimidating for people who have never used them. Some products are labeled as gluten-free, but it is important to know which ingredients typically have gluten. People may follow a gluten-free lifestyle because of health issues, to try to lose weight, or to be healthier. Gluten-free ingredients should never come in contact with products that contain gluten, or any common surfaces.

Gluten is a protein found in wheat, barley, and rye, as well as products made from these grains. Since gluten is added to many products, it may be difficult to determine which have gluten and which do not. Wheat derivatives might be listed as bran, faro, graham, kamut, semolina, spelt, and others. Some oats are also contaminated with wheat.

It is very important to read labels carefully when selecting gluten-free ingredients. Products labeled as gluten-free may contain no gluten or an amount generally considered safe.

Rice and corn are two common gluten-free ingredient that can be made into flour and starch. Potatoes, beans, and quinoa are also popular gluten-free ingredients.

Celiac disease is a common reason to follow a gluten-free diet. In patients with celiac disease, the projections in the small intestine that absorb nutrients are destroyed by gluten. This leads to malabsorption and nutritional deficiency. Symptoms include diarrhea, constipation, depression, and weight loss. The only treatment for celiac disease is to eliminate gluten from the diet.
