The Best Whole Grains To Reduce Your Risk of Disease, Say Dietitians

This little power grain jump easily to the top of the list.

Whole wheat pancakes, buckwheat noodles, mushroom barley soup—wherever we go, grains seem to follow. And this should be no surprise. In addition to being a huge part of our diets, some people often seek out certain grains for their nutritional benefits as many are filled with fiber, packed with vitamins and minerals, and can help lower the risk of disease. According to ​​Hartman Group's 2017 Health and Wellness Report, 58% of consumers are looking to add more whole grains into their diet because of this.

It is important to know, however, that not all grains pack the same punch. For instance, refined grains, which are grains that have been modified from their original state, are a lot less healthy than whole grains. "These grains are modified from their original and natural form, thus reducing their nutrient and dietary fiber content," explains Lon Ben-Asher, MS, RD, LD/N, "This could lead to worsening blood sugar control and reduced satiety potentially leading to weight gain."

The Importance of Whole Grains

On the other hand, whole grains are cereals and pseudocereals that have retained their endosperm, germ, and bran, which are the nutritional powerhouses of the grain. This makes whole grains much healthier than refined grains. "Whole grains give us a great deal of fiber, which will help you feel full and satisfied, along with other important vitamins and minerals," explains Catherine Perez, RD of Plant Based RD and an Ambassador for One Degree Organics, "When looking at the healthiest whole-grain foods to buy, look at the ingredient list. Ideally, the first ingredient should be whole grains, whole wheat, whole oats, etc."

To help better navigate the world of grains, we put together a list that showcases some of the healthiest, and not-so-healthy, grains out there. From ones that are teeming with fiber to others that can pose health risks if not eaten in moderation, here are the most common grains ranked from best to worst by nutritional benefits.

Wheat, although found in a variety of different products ranging from fresh pastas to baked goods, may be one of the least healthy grains due to the fact it is often processed. "Wheat [and rice] may be the least favorable as it pertains to health simply based on the possibility of the process of refinement," explains Ben-Asher, "[Refinement] removes the bran, the storage powerhouse of fiber, vitamins, and minerals, and germ, [which] provides natural healthy fats." Ben-Asher notes how this contributes to reduced satiety and fullness, and overall nutrition. Wheat also contains a high amount of gluten. Tip: It is important to note that whole wheat is far more healthy than refined wheat. Because of this, look for products labeled "100% whole wheat."

Even though white rice is delicious, it should be enjoyed in moderation due to the fact that it is highly processed and may even cause blood sugar spikes. According to research done by Harvard School of Public Health (HSPH), eating white rice regularly may increase the risk for type 2 diabetes. Because of this, it is important to diversify the different types of rice that you include in your diet—for instance, opt for brown, red, or wild rice instead of always reaching for white.

Corn, which often graces holiday table settings and picnic barbecues, is a popular food that is packed with both antioxidants and fiber. However, it is also very starchy—according to WebMD, just one cup of corn has 110 grams of starch. Based on research done by the Mayo Clinic, consuming starch may be linked to weight gain. Because of this, corn, in its most natural form, such as on the cob unbuttered, is much healthier than corn that has been highly processed. "For the ultimate health benefit, minimally processed is best," says Perez, "It's very easy to pop your own popcorn kernels, and then you can flavor it yourself too."

If you like to start your day off with a big bowl of oatmeal, then you'll be happy to hear that oats are full of nutritional benefits. "Oats contain large amounts of beta-glucan, a type of powerful soluble fiber associated with reducing bad cholesterol in the body," says Karen Kawolics, MS RDN LD, MEd, NBC-HWC, and Noom Senior Health Coach (National Board Certified Health Coach), "Beta-glucan has also been given credit for helping to regulate blood sugar levels, providing a sense of fullness, and aiding in colon health." In addition, according to research done by Harvard Health, oats can help lower the risk of heart disease and diabetes. However, it is important to choose oat products that have been minimally processed, as they are more nutritional. For instance, steel-cut or Irish oats are much healthier than quick or instant oats, as the former has been processed less.
