Not only are these grains rich in essential nutrients, but they have also been tied to a number of health benefits, including improved heart health, better blood sugar control and protection against disease. Plus, they’re versatile, delicious and easy to enjoy as part of a number of different recipes.
Here’s what you need to know about whole grains, how they can impact your health and some simple strategies you can use to incorporate them into your diet.
In their natural state growing in the fields, whole grains are actually considered the entire seed (or kernel) of a plant. The seed contains three distinct parts: the bran, germ and endosperm.
The bran — such as wheat bran — is the outer layer of the kernel, the germ is considered the embryo of the plant, and the endosperm provides it with nutrients and energy.
Refined grains are generally stripped of the bran and germ during processing, which extends the shelf life of products and cuts costs for manufacturers. However, it also decreases the nutritional value of the final product.
White flour, pasta, crackers and cereal are a few examples of refined grains.
In order for a food to secure a slot on the whole grains list, it must contain all three parts of the kernel. Not only does this maximize the nutrient profile of the grain, but it also boosts the potential health benefits.
There are many potential benefits of whole grains and several reasons you may want to consider adding a serving or two to your diet. Here are a few of the top health benefits of whole grains.
Whole grains are considered nutrient-dense foods, meaning that they provide a wealth of important nutrients in each serving. In particular, whole grains are generally rich in fiber, B vitamins, antioxidants and beneficial plant compounds.
Specific whole grains may also contain a hearty dose of other micronutrients as well. Oats, for example, are an excellent source of manganese, selenium, zinc, phosphorus and iron.
Meanwhile, quinoa contains plenty of protein, magnesium, folate and copper.
Because whole grains contain the bran, endosperm and germ of the kernel, they are typically much higher in fiber than their refined counterparts. Fiber travels through the digestive tract slowly and plays an integral role in several aspects of health.
However, it’s perhaps most well-known for its ability to promote regularity and enhance digestive health.
According to one meta-analysis out of China, increasing fiber intake through high-fiber foods could help increase stool frequency in those with constipation. Other research indicates that fiber could also aid in the prevention of other digestive conditions, including hemorrhoids, diverticulitis and gastroesophageal reflux disease (GERD).
Many people use whole grain foods to lose weight, and for good reason. Because whole grains are a great source of fiber, they can help keep you feeling full between meals to decrease hunger and combat cravings.
In fact, one study found that increasing total intake of fiber could be linked to a lower risk of weight gain and fat gains in women.
What’s more, other studies show that eating whole grains could be associated with a lower risk of weight gain and obesity. In one study, eating at least three servings of whole grains per day was tied to reductions in body mass index (BMI) and belly fat in over 119,000 people.
Incorporating more whole grains in your diet can help keep your heart healthy and strong. Whole grains may also protect against heart disease and stroke, both of which are major problems in the United States and around the globe.
Impressively enough, one review published in BMJ found that consuming three servings of whole grains per day was associated with a 22 percent lower risk of heart disease. Plus, another study conducted in 2015 reported that eating more whole grains could also be linked to a significantly lower risk of stroke.
Whole grains are a great source of fiber, which can slow the absorption of sugar in the bloodstream to keep blood sugar levels stable. Studies also show that whole grains could help decrease insulin levels and improve insulin sensitivity, which enhances the body’s ability to transport sugar out of the bloodstream and into the cells where it can be used as fuel.
Furthermore, a review conducted by the Norwegian University of Science and Technology showed that a higher intake of whole grains was associated with a reduced risk of developing type 2 diabetes, indicating that these grains may possess powerful anti-diabetes properties.
Whole grains are widely considered one of the top cancer-fighting foods thanks to their content of dietary fiber, antioxidants and phytochemicals. Certain compounds in whole grains, like gallic acid, ferulic acid and vitamin C, can help fight free radical damage and decrease oxidative stress, both of which can contribute to the development of cancer.
One review out of New York evaluated the results of 20 studies examining the link between whole grain consumption and cancer. Of the 20 studies, six showed that regular consumption of whole grains may be linked to up to a 47 percent reduced risk of cancer.
Whole grain consumption may be especially beneficial against cancers affecting the digestive tract, including stomach and colorectal cancer.
Although acute inflammation is an important part of the immune process, chronic inflammation is thought to contribute to autoimmune disorders like rheumatoid arthritis, along with chronic conditions like heart disease, cancer and diabetes.
Fortunately, adding more healthy whole grains to your diet has been shown to help fight inflammation and improve overall health. In a study in American Journal of Clinical Nutrition, swapping refined grains out for whole grain products was effective at reducing several markers of inflammation in the body.
There are many different types of whole grains, each of which boasts its own specific set of vitamins, minerals, antioxidants and health benefits. Here are a few of the healthiest grains that you may want to consider adding to your next shopping list:
Wondering how to eat whole grains and how you can enjoy these healthy foods as part of a balanced diet? From trading the all-purpose flour for whole wheat flour in your favorite baked goods to adding a serving of sprouted, whole grains bread like Ezekiel bread to your daily diet, there are plenty of ways to quickly ramp up your intake.
Oats, for instance, are one of the most popular whole grain foods for breakfast and can easily be enjoyed topped with berries, nuts and seeds. Meanwhile, brown rice, quinoa, buckwheat and barley are great options for a side dish that can round out any meal.
Alternatively, try swapping out white bread for whole grain bread to bump up the nutritional value instantly.

Although whole grains can be a beneficial dietary addition for most, some people may need to limit their consumption.
In particular, those with celiac disease or a sensitivity to gluten should stick to gluten-free whole grains like quinoa, brown rice and millet to avoid adverse effects on health.
Keep in mind that certain grains that are naturally gluten-free can also be cross-contaminated, including oats. For this reason, it’s important to look for products that are certified gluten-free if you have celiac disease or a gluten sensitivity.
Some types of grains are also often genetically modified. For example, it’s estimated that at least 90 percent of corn cultivated in the United States is genetically modified.
Many people choose to avoid GMO crops due to concerns about food safety and the long-term effects on health. Selecting organic whole grains is an easy way to minimize your exposure to GMO crops while still taking advantage of the benefits of whole grains.
Some grains may also contain antinutrients, which can impair the absorption of certain vitamins and minerals in the body. Selecting sprouted varieties, such as sprouted grain bread, can improve digestion and decrease the amount of antinutrients in the final product.
