The Hype Over Grain-Free Pet Food. Are grain free pet foods really better?

The Hype Over Grain-Free Pet Food readmore
A grain-free trend in pet food emerged as scientists began studying the diets of dogs and cats in the wild and the diets of their ancestors, and found that their bodies have a limited ability to extract nutrients from non-meat sources. 

Although many animals do well on grain-free diets, some animals do well on diets that do include grains. Veterinarians sometimes recommend grain-free diets for animals who have grain sensitivities because removing grains from their diet often improves skin problems, allergies, digestive problems, and frequently impacted anal glands.

Grains are not necessarily bad ingredients in pet foods. The key is choosing the grains that have the most nutritional value to dogs and cats, cooking grains properly, and using grains in proper proportions to meat.

What are grains?

Grains are seeds from grasses. Grains contain fiber, vitamins and minerals, high amounts of carbohydrates, small amounts of protein, and a handful of other useful nutrients.

Most raw grains are poorly digested by dogs and cats. However, after they are ground and adequately cooked they’re more digestible and their nutrients are more easily absorbed. The grains that are best for our companion animals are whole or whole ground rice, oats, barley, and millet.

Why are grains used in pet food?

High quality pet food companies include grain ingredients for nutritional benefits and because grains are ideal for binding ingredients together to form kibble, pate, and other food consistencies. It’s like using bread crumbs in meatloaf to hold the ingredients in a loaf shape.

Some pet food companies also use grain ingredients as a protein source because veterinarians sometimes recommend that certain individual animals have reduced animal-derived proteins in their diets.

Also, dogs and cats do require some carbohydrates and non-meat nutrients. Dogs can only use a limited amount of protein per day, so when their bodies require a high amount of calories per day, they can get quick, usable energy from carbohydrates.

However, because grain ingredients are much cheaper than meat ingredients, many lower quality pet food companies use grains simply as a filler. Fillers help animals feel full but contain little (or no) nutritional value. The grains most commonly used as fillers are wheat and corn.

Why do grain-free foods still contain non-meat sources?

In addition to providing useful carbohydrates, one of the main reasons that pet foods include non-meat sources is to bind ingredients together. The non-grain ingredients most often used for this purpose are tapioca, potatoes, peas, and carrots.

Are grain-free pet foods really better than foods that include grains?

Obviously animals with allergies or sensitivities to grains should be on grain-free diets.

 As pets age, their digestive systems have a harder time processing carbohydrate ingredients. Dogs and cats can develop food sensitivities to grains, usually due to grain glutens, when their diets include a disproportionate amount of grain ingredients. These animals are healthier when their food contains only hypoallergenic ingredients and non-grain carbohydrate sources, such as potatoes and tapioca.              

Diets that are grain-free tend to be higher in protein than other diets, so when veterinarians recommend high-protein diets, grain-free foods are a good option. However, grain-free diets are not the same as low-carbohydrate diets.

Going grain-free isn’t always the best option for an animal. For example, senior pets and those with certain health problems may need diets that are lower in protein or higher in fiber.

To find out the ideal diet for an individual animal, consider working with a veterinary nutritionist who has received special training in the nutritional management of both healthy animals and those with diseases. There are many professional organizations that can help you find a veterinary nutrition specialist in your area, such as the American Academy of Veterinary Nutrition (
