The term "gluten free" means that certain product does not contain any wheat or grain products in it. Many people like to eat a gluten free diet as a health measure but some people have an actual disease that prevents them from eating products that are not gluten free. This disease is called Celiac disease. If you have Celiac disease then there are many products that you will not be able to eat based on your food allergies.
Some of these products include breads, baked goods, cereals, soups, pastas, and beer. You must also be careful about what you eat, for example food that is processed in plants can also contain gluten. The good news is that many companies are starting to produce more and more gluten free things as awareness against gluten rises.
