High fiber grains, including quinoa and oats, can reduce the number of carbohydrates your body absorbs. They can also provide other key nutrients. Read on for more good options.

Grains are often completely off-limits on many low carb diets.

However, several types of grains are high in fiber. This means you can enjoy them in moderation as part of a healthy, carb-controlled diet.

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.

Here are some of the top grains that are low in carbs, plus a few others that you may want to limit on a low carb diet.

How we define low carbohydrate

We define a low carbohydrate meal as a meal with 45 grams or less of carbohydrates per serving. If you’re looking for a low carbohydrate snack, look for a snack with 15 grams or less of carbohydrates per serving.

Although many types of grains can fit into a healthy, low carb diet, some types of grains contain a high number of carbs that are also low in fiber.

Refined grains, in particular, are grain products that have undergone processing to alter their texture and prolong 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
  • crackers
  • breakfast cereal
  • pizza dough
  • potato chips
  • instant oatmeal

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.

Summary

Refined grains have undergone processing to improve their texture and shelf life. These foods are typically lower in fiber and higher in net carbs than whole grains.

Although many low carb diets do not eliminate grains, many varieties can fit into a healthy, carb-controlled diet.

In fact, many types of grains are high in fiber and low in net carbs, which is the number of carbs the body actually absorbs.

For best results, be sure to select whole grain varieties and steer clear of grains that have been heavily processed or refined whenever possible.
