The Nutritional Value of Blueberries
Blueberries are nutrient-dense, containing a wide range of vitamins, minerals, and antioxidants. A 1-cup (148-gram) serving of blueberries contains just 84 calories but provides 3.6 grams of fiber, 16% of the recommended daily intake of vitamin C, and 22% of the recommended daily intake of manganese. Blueberries are also rich in flavonoids, a type of antioxidant that helps protect the body against damage from free radicals.
The Health Benefits of Blueberries
1. Blueberries are good for your heart.
Blueberries have been shown to lower blood pressure, reduce levels of oxidized LDL cholesterol, and protect against heart disease. One study found that people with a high risk of heart disease who consumed 2 ounces (50 grams) of freeze-dried blueberries per day for 8 weeks experienced a 4-6% reduction in blood pressure. Another study found that a daily 2-ounce serving of freeze-dried blueberries lowered LDL oxidation by 28% in people with obesity.
2. Blueberries may improve brain function and memory.
The antioxidants in blueberries appear to benefit aging neurons, leading to improvements in cell signaling and delaying mental decline. Human studies have found that regular blueberry intake is associated with delays in mental aging of up to 2.5 years.
3. Blueberries may reduce the risk of cancer.
Blueberries are rich in antioxidants that can help prevent DNA damage and reduce the risk of cancer. Studies have found that blueberries can inhibit the growth and spread of cancer cells in vitro, and one study in 93,600 nurses found that those with the highest intake of anthocyanins (the main antioxidants in blueberries) were at a 32% lower risk of heart attacks.
4. Blueberries may benefit people with diabetes.
Blueberries have been shown to improve insulin sensitivity and glucose metabolism, potentially lowering the risk of metabolic syndrome and type 2 diabetes. In one study, two blueberry smoothies daily caused major improvements in insulin sensitivity in 32 obese people with insulin resistance.
5. Blueberries may aid exercise recovery.
Blueberry supplements have been found to lessen the damage that occurs at a molecular level after strenuous exercise, minimizing soreness and reducing muscle performance. In one study, blueberries accelerated muscle recovery after strenuous leg exercises in 10 female athletes.
