What are the benefits of beta glucan?

Boosts heart health

There’s solid evidence that beta glucan can boost heart health. Several studies suggest that beta glucan may lower cholesterol and triglycerides. One found that eating oats with at least 3 g of beta glucan daily reduced bad cholesterol (LDL) levels between 5 and 7 percent.

Regulates blood sugar levels

It may help reduce the risk of type 2 diabetes. It may also improve blood sugar control for those who already have diabetes.

Stimulates immune system

Researchers believe that beta glucan could have some positive effects on the immune system. However, more research is necessary.

Most research to date has been in the form of animal trials. Scientists think beta glucan may be able to stimulate the immune system and help the body fight off disease and infection more effectively. However, the human immune system is complicated and researchers are still learning how it works. It may take some time before we know the exact effects beta glucan has and if it can improve immune system function.

How does beta glucan work?

Because it’s a soluble fiber, beta glucan slows down food transit in the intestines. This means that it takes longer for the body to digest food. Slower digestion means the body doesn’t absorb sugar as quickly, reducing the likelihood of blood sugar spikes and helping keep blood sugar levels stable. Beta glucan is indigestible, so it goes through the whole digestive tract. As it travels through, it can take cholesterol out with it, lowering levels.

Beta glucan is naturally in some foods, and is generally considered safe. If you choose to take supplements, make sure they’re from a reliable source. Talk to your doctor before taking any supplements.

People with conditions such as rheumatoid arthritis, lupus, multiple sclerosis, asthma, and inflammatory bowel disease may need to especially use caution with beta glucan supplements. This is because their immune system is already overactive. Be sure to talk to your doctor before taking supplements if you have any chronic health conditions.

What’s the takeaway?

Science may not have unlocked all of beta glucan’s potential health benefits, but we do know that it has a role in improving heart
health and preventing diabetes. The best way to get fiber is through your diet. If you haven’t already, think about switching to
whole grains.
