A Dietitian Shares 3 Reasons to Add Blueberries to Your Diet

If you want an easy way to increase your nutrient intake, blueberries are worth considering. These small berries are loaded with antioxidants, fiber, vitamins, and minerals that can benefit several areas of health, from digestion to cardiovascular function.

1. They May Aid Digestion and Gut Health

Blueberries contain nutrients that can play a meaningful role in supporting gut health. They are a good source of fiber, with 3.6 grams per cup, which helps promote regular bowel movements and healthy digestion.

They also contain polyphenols, which are natural plant compounds that support beneficial gut bacteria. Because polyphenols are not completely broken down in the small intestine, they make their way to the large intestine intact. There, they may help maintain a healthy gut microbiome and support the gut barrier.

Along with other plant compounds such as flavonoids and anthocyanins, the polyphenols in blueberries act as antioxidants and may help reduce inflammation throughout the body, including in the digestive system.

2. They May Support Memory and Brain Health

Although more research is still needed, blueberries may be a simple addition to the diet for supporting long-term brain health. Research has found that regularly eating blueberries may help with memory, learning, and overall brain function, particularly in older adults.

This effect is likely tied to the berries’ beneficial plant compounds, which help defend brain cells against oxidative stress and inflammation.

3. They May Benefit Heart Health

Blueberries may also be helpful for heart health. Some studies suggest that regularly eating them can improve blood pressure and support healthy blood vessel function, both of which are important for the heart.

High blood pressure is a major risk factor for heart attack. In one study, greater blueberry intake was associated with a 33% lower risk of heart attack in women.

Anthocyanins in particular have been linked to better blood vessel function and lower inflammation. The fiber and other compounds in blueberries may also help support healthy cholesterol levels.
