Whole grains have been consumed for tens of thousands of years (1).
But many modern diets, such as the paleo diet, claim that eating grains is bad for your health.
While refined grains are definitely linked to health problems like obesity and inflammation, whole grains are another story.
There are legitimate health benefits to eating whole grains, including a lower risk of diabetes, heart disease and high blood pressure.
This article lists the top nine health benefits of whole grains, as well as who might want to avoid them.
What Are Whole Grains?
Grains are the seeds of grass-like plants called cereals. Some of the most common varieties are corn, rice and wheat.
Whole grain kernels have three parts (3):
- Bran: This is the hard, outer shell. It contains fiber, minerals and antioxidants.
- Endosperm: The middle layer of the grain is mostly made up of carbs.
- Germ: This inner layer has vitamins, minerals, protein and plant compounds.
Grains can be rolled, crushed or cracked, but as long as these three parts are still present in their original proportion, they're considered whole grains.
Refined grains have had the germ and bran removed, leaving only the endosperm.
Although enriched refined grains have had some vitamins and minerals added back, they're still not as healthy or nutritious as the whole versions.
There are many kinds of whole grains, including:
- Brown rice
- Whole rye
- Wild rice
- Wheat berry
Products made from these foods are also considered whole grain foods. These include bread, pasta and some breakfast cereals.
When you're purchasing processed whole grain products, make sure you read the ingredients list to make sure they're made entirely from whole grains, not a mixture of whole and refined grains.
Also keep an eye on the sugar content, especially in the case of breakfast cereals, which often contain large amounts of added sugar. Seeing "whole grain" on the packaging does not automatically mean that the product is healthy.
Bottom Line: Whole grains contain all three parts of the grain. There are many different kinds, including whole wheat and whole corn, oats, brown rice and quinoa.
1. They're High in Nutrients and Fiber
Whole grains deliver many important nutrients. Here are some of the key nutrients found in whole grains:
- Fiber: The bran provides most of the fiber in whole grains.
- Vitamins: Whole grains are particularly high in B vitamins, including niacin, thiamin and folate (4, 5).
- Minerals: They also contain a good amount of minerals, such as zinc, iron, magnesium and manganese.
- Protein: Whole grains provide several grams of protein per serving.
- Antioxidants: Several compounds in whole grains act as antioxidants. These include phytic acid, lignin and sulfur compounds (6).
- Plant compounds: Whole grains deliver many types of plant compounds that play a role in preventing disease. These include lignans, stanols and sterols (7).
The exact amounts of these nutrients differ depending on the type of grain.
- Fiber: 3 grams
- Manganese: 69 percent of the RDI
- Phosphorous: 15 percent of the RDI
- Thiamin: 14 percent of the RDI
- Magnesium: 12 percent of the RDI
- Copper: 9 percent of the RDI
- Zinc and iron: 7 percent of the RDI
Bottom Line: Whole grains deliver a variety of important nutrients, including vitamins, minerals, protein, fiber and other healthy plant compounds.
2. They Lower Your Risk of Heart Disease
One of the biggest health benefits of whole grains is that they lower your risk of heart disease, which is the leading cause of death worldwide (8).
A 2016 review analyzed the results of 10 studies and found that three one-ounce servings of whole grains daily may lower the risk of heart disease by 22 percent (9).
In fact, eating up to seven ounces of whole grains per day was linked to a lower risk of heart disease.
Those who ate the highest proportion of whole grains in relation to their total carb intake had a 47 percent lower risk of heart disease.
The researchers concluded that heart-healthy diets should include more whole grains and fewer refined grains.
While most studies lump together all types of whole grains and make it hard to tease apart the benefits of individual foods, whole grain breads and cereals, as well as added bran, have been specifically linked to a lower risk of heart disease (9).
Bottom Line: Eating whole grains may lower your risk of heart disease, especially when they replace refined grains.
3. They Lower Your Risk of Stroke
Whole grains may also help lower your risk of stroke (11).
In an analysis of six studies including nearly 250,000 people, those eating the most whole grains had a 14 percent lower risk of stroke than those eating the fewest (11).
Furthermore, three compounds in whole grains—fiber, vitamin K and antioxidants—can reduce the risk of stroke.
Bottom Line: As part of a heart-healthy diet, whole grains may help lower your risk of stroke.
4. They Reduce Your Risk of Obesity
Whole grains and products made from them are more filling than refined grains and a lot of research suggests that they may lower your risk of obesity.
Another study that reviewed research from 1965 to 2010 found that whole grain cereal and cereal with added bran were linked to a modestly lower risk of obesity (15).
Bottom Line: A lot of research from the past 45 years has suggested that whole grains are linked to a lower risk of obesity.

Tuna auctions are a tourist spectacle in Tokyo. Outside the city's most famous fish market, long queues of visitors hoping for a glimpse of the action begin to form at 5 a.m. The attraction is so popular that last October the Tsukiji fish market, in operation since 1935, moved out from the city center to the district of Toyosu to cope with the crowds.

Kristan Porter grew up in a fishing family in the fishing community of Cutler, Maine, where he says all roads lead to one career path: fishing. (Porter's father was the family's lone exception. He suffered from terrible seasickness, and so became a carpenter.) The 49-year-old, who has been working on boats since he was a kid and fishing on his own since 1991, says that the recent warming of Maine's cool coastal waters has yielded unprecedented lobster landings.
The climate crisis is getting costly. Some of the world's largest companies expect to take over one trillion in losses due to climate change. Insurers are increasingly jittery and the world's largest firm has warned that the cost of premiums may soon be unaffordable for most people. Historic flooding has wiped out farmers in the Midwest.

The Ganges is a lifeline for the people of India, spiritually and economically. On its journey from the Himalayas to the Bay of Bengal, it supports fishermen, farmers and an abundance of wildlife.
The river and its tributaries touch the lives of roughly 500 million people. But having flowed for millennia, today it is reaching its capacity for human and industrial waste, while simultaneously being drained for agriculture and municipal use.
Here are some of the challenges the river faces.

As a growing number of states move to pass laws that would criminalize pipeline protests and hit demonstrators with years in prison, an audio recording obtained by The Intercept showed a representative of a powerful oil and gas lobbying group bragging about the industry's success in crafting anti-protest legislation behind closed doors.
Speaking during a conference in Washington, DC in June, Derrick Morgan, senior vice president for federal and regulatory affairs at the American Fuel & Petrochemical Manufacturers (AFPM), touted "model legislation" that states across the nation have passed in recent months.
AFPM represents a number of major fossil fuel giants, including Chevron, Koch Industries and ExxonMobil.
"We've seen a lot of success at the state level, particularly starting with Oklahoma in 2017," said Morgan, citing Dakota Access Pipeline protests as the motivation behind the aggressive lobbying effort. "We're up to nine states that have passed laws that are substantially close to the model policy that you have in your packet."

"This legislation has potential to punish public participation and mischaracterize advocacy protected by the First Amendment."https://t.co/bmiHjONEhy
The audio recording comes just months after Texas Gov. Greg Abbott signed into law legislation that would punish anti-pipeline demonstrators with up to 10 years in prison, a move environmentalists condemned as a flagrant attack on free expression.
"Big Oil is hijacking our legislative system," Dallas Goldtooth of the Indigenous Environmental Network said after the Texas Senate passed the bill in May.
As The Intercept's Lee Fang reported Monday, the model legislation Morgan cited in his remarks "has been introduced in various forms in 22 states and passed in ... Texas, Louisiana, Oklahoma, Tennessee, Missouri, Indiana, Iowa, South Dakota, and North Dakota."
"The AFPM lobbyist also boasted that the template legislation has enjoyed bipartisan support," according to Fang. "In Louisiana, Democratic Gov. John Bel Edwards signed the version of the bill there, which is being challenged by the Center for Constitutional Rights. Even in Illinois, Morgan noted, 'We almost got that across the finish line in a very Democratic-dominated legislature.' The bill did not pass as it got pushed aside over time constraints at the end of the legislative session."
Many of the state bills restricting the right to protest have been "drafted by companies and passed through groups like ALEC, the secretive group of corporate lobbyists trying to rewrite state laws to benefit corporations over people." @greenpeaceusa https://t.co/ZxpTjWdrwT— Stand Up To ALEC (@StandUpToALEC) May 6, 2019
