From the Guidelines
Berries are a crucial component of a healthy diet, offering numerous benefits that can improve overall health and reduce the risk of chronic diseases, and should be consumed regularly, with a recommended intake of 1-2 servings (about 1/2 to 1 cup) of mixed berries daily. The health benefits of berries include:
- Antioxidant effects: Berries are rich in antioxidants like anthocyanins, flavonoids, and ellagic acid, which help protect cells from damage caused by free radicals 1.
- Heart health: Regular berry consumption can improve cardiovascular health by lowering blood pressure and reducing inflammation, as emphasized by the American Heart Association's diet and lifestyle recommendations revision 2006 1.
- Blood sugar regulation: Berries may help improve insulin sensitivity and glucose metabolism, potentially aiding in diabetes management, with studies suggesting that higher intakes of berries are associated with reduced diabetes risk 1.
- Cognitive function: Some studies suggest berries can enhance memory and slow age-related cognitive decline.
- Cancer prevention: Certain compounds in berries have shown potential in inhibiting tumor growth and reducing cancer risk.
- Digestive health: The fiber content in berries supports healthy digestion and promotes gut health.
- Weight management: Low in calories but high in fiber, berries can aid in weight control by promoting feelings of fullness.
To incorporate these benefits, it is recommended to consume a variety of berries, including blueberries, strawberries, and raspberries, and to add them to yogurt, oatmeal, smoothies, or enjoy them as a snack. Fresh or frozen berries are equally beneficial, and techniques that preserve nutrient and fiber content without adding unnecessary calories, saturated or trans fat, sugar, and salt are recommended 1.
