Rice with the bran layer left on, which keeps more fiber, B vitamins and minerals than white rice. It is well digested by most dogs and is a common carbohydrate in sensitive-stomach foods. It digests more slowly than white rice and keeps blood sugar steadier, so it turns up in weight-control foods too. For most dogs and cats it is an unremarkable energy source.

A staple of grain-free recipes, supplying starch, fiber and plant protein. Peas were common in the diets examined in a federal investigation into heart disease in dogs; the investigation did not establish a cause and no ingredient was banned. Pea protein high on a list can inflate the protein number with a plant source. Pea allergy is rare. Not a problem, but worth noticing when it appears in several forms in one recipe.

A root vegetable used as a carbohydrate source, especially in grain-free foods. It supplies energy, fiber and beta carotene and is well digested by dogs. There is no good evidence it beats rice or oats nutritionally, though it is a reasonable choice for pets that do poorly on grains. Like any starch, a food that lists it high is a starch-heavy food.

The dried cells of yeast, often a by-product of brewing. It is rich in B vitamins, protein and minerals, improves flavor, and contains compounds that may support gut bacteria. Despite a persistent myth, there is no evidence it repels fleas. Yeast is an uncommon allergen in pets. Yeast culture is a slightly different product, a fermented feed that supplies similar nutrients.

A plant fat high in medium-chain triglycerides, fats the body can burn quickly without the usual digestion steps. Those fats are the reason coconut oil appears in some senior and brain-support foods, where small studies of medium-chain fats in older dogs showed modest cognitive benefits; a food's coconut oil is a lower dose of the same fats. It supplies almost no essential fatty acids, so a food cannot rely on it as the only fat. It is calorie-dense and fine in the small amounts used.

A legume plant, the same one fed to horses, dried and added as a source of fiber, vitamins and chlorophyll. It appears in small amounts and gives kibble a greenish fleck. Alfalfa is safe for dogs and cats at these levels. The protein it contains is small and poorly digested by carnivores, so it adds little nutrition.
