Oats are natural and may be grown sustainably if they are grown organically and not treated with toxic chemicals. Oats do not require a lot of water to grow and they are a low maintenance crop which means that they are fairly resilient to pests (reducing the need for pesticides). Oats are particularly sustainable when they are part of a sustainable crop rotation helping to maintain the nutrients in the soil.
Oat is a cereal grain grown for its seed. Oats can be found on store shelves as a single ingredient or added to baked goods, bread, muesli and granola.
Oats are available in various forms which include steel-cut oats, rolled oats and instant oats. Steel-cut oats are created from oat groats (husked oat kernel) that are sliced by a rotating, bladed machine to create steel-cut oats. Rolled oats are also made from whole groats that are steamed (soften the grain) then rolled to flatten the oats, and then moved through a stream of air to dry out the oats. Rolled oats come in a variety of thicknesses and quicker cooking times. Oats are also crushed into oatmeal (porridge) or ground into flour. Ground oats are also mixed with water (and other ingredients) to create oat milk, a plant-based alternative to dairy milk.
Oats are naturally gluten-free however, oats can often be cross-contaminated with wheat which contains gluten. This is why you should always buy certified gluten-free oats that have been packaged in a gluten-free facility if you need to avoid gluten.
Oats contain small amounts of gliadin. Celiac disease is an intestinal allergic disorder that causes individuals to be sensitive to gluten and gliadin, proteins in wheat and rye. People with celiac disease cannot digest the nutrients in these grains.
