High fiber grains, including quinoa and oats, can reduce the number of carbohydrates your body absorbs. They can also provide other key nutrients.
Grains are often completely off-limits on many low carb diets.
However, several types of grains are high in fiber, and you can enjoy them in moderation as part of a healthy, carb-controlled diet.
This is because foods that are high in fiber contain a lower number of net carbs, which is the number of carbs the body absorbs. You can calculate net carbs by subtracting the grams of fiber from the total grams of carbs (

Although many types of grains can fit into a healthy, low carb diet, some types of grains contain a high number of carbs and are low in fiber.
Refined grains, in particular, are grain products that have undergone processing to improve their texture and shelf life.
This results in a lower content of fiber, which can increase the number of net carbs in the final product.
A few examples of grains that are high in carbs include:
- white bread
- refined pasta
- white rice
- breakfast cereal
- pizza dough
- potato chips
- instant oatmeal
Additionally, keep in mind that if you’re cutting carbs, you may still need to limit many healthy whole grains, depending on how restrictive your diet is.
