Many whole grains, like quinoa and buckwheat, are naturally gluten-free and provide beneficial nutrients.
Although gluten is not a problem for most people, some may not tolerate it well.
Celiac disease is an autoimmune disease that triggers an immune response to gluten. For those with this disease or a non-celiac gluten sensitivity, eating gluten can cause symptoms like bloating, diarrhea, and stomach pain (
Many of the most commonly consumed grains contain gluten. However, there are plenty of nutritious gluten-free grains available, too.
Here are 9 gluten-free grains that are super healthy.
Sorghum is typically cultivated as both a cereal grain and animal feed. It’s also used to produce sorghum syrup, a type of sweetener, as well as some alcoholic beverages.
This gluten-free grain contains beneficial plant compounds that act as antioxidants to reduce oxidative stress and lower your risk of chronic disease (
Additionally, sorghum is rich in fiber and can help slow the absorption of sugar to keep your blood sugar levels steady.
One study compared blood sugar and insulin levels in 10 people after eating a muffin made with either sorghum or whole-wheat flour. The sorghum muffin led to a greater reduction in both blood sugar and insulin than the whole-wheat muffin (
A 2010 test-tube and animal study suggests that black sorghum bran possesses significant anti-inflammatory properties due to its high content of these plant compounds (
One cup (192 grams) of sorghum contains 13 grams of fiber, 20 grams of protein, and 19% of the daily value for iron (
Sorghum has a mild flavor and can be ground into flour for baking gluten-free goods. It can also replace barley in recipes like mushroom-barley soup.
Summary: Several studies have shown that sorghum
is high in plant compounds and may help reduce inflammation and blood sugar
Quinoa has quickly become one of the most popular gluten-free grains. It’s incredibly versatile and a good source of fiber and plant-based protein.
Additionally, quinoa is a good source of protein and one of the few plant foods considered a complete protein source.
One cup (185 grams) of cooked quinoa provides 8 grams of protein and 5 grams of fiber. It’s also packed with micronutrients and fulfills much of your daily magnesium, manganese, and phosphorus requirements (
Quinoa is the perfect ingredient to make gluten-free crusts and casseroles. Quinoa flour can also be used to make pancakes, tortillas, or quick bread.
Summary: Quinoa contains a good amount of
antioxidants. It’s also one of the few plant foods containing all the essential
Oats are very healthy. They also stand out as one of the best sources of oat beta-glucan, a type of soluble fiber with advantages for your health.
A review of 28 studies found that beta-glucan decreased both LDL (bad) and total cholesterol without affecting HDL (good) cholesterol (
One cup (81 grams) of dry oats provides 8 grams of fiber and 11 grams of protein. It is also high in magnesium, zinc, selenium, and thiamine (vitamin B1) (
Although oats are naturally gluten-free, many brands of oats may contain trace amounts of gluten. Oat products may become contaminated with gluten when they are harvested and processed.
If you have celiac disease or a gluten sensitivity, be sure to look for oats labeled as certified gluten-free.
Keep in mind that a small proportion of people with celiac disease may be sensitive to avenin, a protein found in oats. However, oats that are gluten-free should be fine for the majority of gluten-intolerant people (
A hot bowl of oatmeal is the most popular way to enjoy oats, but you can also add oats to pancakes, granola bars, or parfaits for extra fiber and nutrients.
Summary: Oats contain beta-glucan, which may
decrease blood cholesterol and help regulate blood sugar levels.
Despite its name, buckwheat is a grain-like seed that’s unrelated to wheat and gluten-free.
Eating buckwheat may also help reduce some risk factors for heart disease.
In one study, buckwheat intake was associated with lower total and LDL (bad) cholesterol, as well as a higher ratio of HDL (good) to total cholesterol (
Another study observed similar findings, showing that those who ate buckwheat had a lower risk of high blood pressure, high cholesterol, and high blood sugar (
One cup (168 grams) of cooked buckwheat groats delivers 5 grams of fiber and 6 grams of protein and is a rich source of magnesium, copper, and manganese (
Try soba noodles made from buckwheat as a gluten-free swap for traditional pasta. Alternatively, use buckwheat to add a bit of crunch to soups, salads, or even veggie burgers.
Summary: Buckwheat is rich in antioxidants and
has been associated with reductions in heart disease risk factors, such as
blood cholesterol levels.
A 2014 test-tube study suggests that the compounds in amaranth block inflammation by preventing the activation of a pathway that triggers inflammation (
Thanks to its high fiber content, amaranth may also decrease several heart disease risk factors.
In fact, one animal study found that amaranth seeds decreased both blood triglycerides and LDL (bad) cholesterol levels (
One cup (246 grams) of cooked amaranth contains 5 grams of fiber and 9 grams of protein. It also meets 29% of your daily iron needs and contains a good amount of magnesium, phosphorus, and manganese (
You can use amaranth as a substitute for other grains, such as rice or couscous. Amaranth that has been cooked and then chilled can also be used in place of cornstarch as a thickening agent for soups, jellies, or sauces.
Summary: Some studies show that amaranth may reduce
inflammation and several risk factors for heart disease.
As one of the smallest grains in the world, teff is a tiny but powerful grain.
Despite being just 1/100 the size of a kernel of wheat, teff packs a nutritional punch.
One cup (252 grams) of cooked teff contains 10 grams of protein and 7 grams of fiber. It also provides plenty of B vitamins, especially thiamine (
For gluten-free baking, try substituting teff in part or in whole for wheat flour. Teff can also be mixed into chili, made into porridge, or used as a natural way to thicken dishes.
Summary: Teff is one of the smallest grains in
the world but high in fiber and protein. Both of these nutrients are essential
to your health and come with many benefits.
Corn, or maize, is among the most popular gluten-free cereal grains consumed around the world.
In addition to being high in fiber, corn is a rich source of the carotenoids lutein and zeaxanthin, which are plant pigments that act as antioxidants (
One study found that those with a high intake of carotenoids had a 43% lower risk of age-related macular degeneration compared with those with a low intake (
One cup (149 grams) of sweet corn contains 4 grams of fiber and 5 grams of protein. It’s also high in pantothenic acid and a good source of vitamin B6, thiamine, and manganese (
Corn can be boiled, grilled, or roasted for a healthy side dish to a well-balanced meal. Enjoy it right off the cob or add it to a salad, soup, or casserole.
Summary: Corn is high in fiber and a good source
of lutein and zeaxanthin, two carotenoids that are associated with a decreased
risk of eye disease.
Although brown and white rice come from the same grain, white rice has had the bran and germ of the grain removed during processing.
Thus, brown rice has more fiber and a higher amount of many micronutrients, making it one of the healthiest gluten-free grains around.
Both varieties of rice are gluten-free, but studies show that replacing white rice with brown rice comes with added health benefits.
One cup (202 grams) of cooked brown rice contains 3 grams of fiber and 6 grams of protein. It also provides a good portion of your magnesium and selenium needs for the day (
Brown rice makes a delicious side dish on its own or can be combined with vegetables and a lean source of protein to create a filling meal.
Summary: Brown rice is high in fiber and
associated with decreased risks of diabetes, weight gain, and heart disease
when used in place of white rice.
When you have celiac disease or a sensitivity to gluten, following a gluten-free diet can be challenging.
