One study found that drinking goji berry juice for 30 days increased blood antioxidant levels of healthy older Chinese adults ( 23).Īnother study found that drinking goji berry juice for 2 weeks increased metabolism and reduced waist size in people with overweight ( 24). Like many other berries, goji berries contain antioxidant polyphenols. This study, along with a second similar study, suggested that eating goji berries could raise blood zeaxanthin levels ( 21, 22). One study of 150 older adults found that eating 14 grams of a proprietary milk-based formulation of goji berry each day reduced age-related decline in eye health. Goji berries also contain high levels of vitamin A and zeaxanthin, both of which are important for eye health. One ounce (28 grams) of dried goji berries provides ( 20): They have recently become very popular in the Western world. Goji berries, also known as wolfberries, are native to China and used in traditional medicine. Raspberries are full of fiber and antioxidant polyphenols. More research is needed to confirm the benefits of black raspberries. Other studies have shown that black raspberries may reduce inflammation in people with metabolic syndrome ( 19). Studies have associated black raspberries with reduced risk factors for heart disease, such as blood pressure and blood cholesterol ( 16, 17, 18). In fact, they may be especially good for heart health. However, there are many different types of raspberries.īlack raspberries, for example, have been shown to have several health benefits, too. The most commonly consumed raspberries are the American red or European red varieties. One study showed that when cyclists consumed a drink containing raspberries and other berries, oxidative stress caused by exercise decreased significantly ( 15). Raspberries also contain antioxidant polyphenols called ellagitannins, which can help reduce oxidative stress ( 14). One cup (123 grams) of raspberries provides ( 13): Raspberries are often used in desserts and are a very good source of fiber. Eating blueberries may help reduce risk factors for heart disease and diabetes. Summaryīlueberries contain good amounts of fiber, vitamin C, and antioxidant anthocyanins. However, more research is needed to determine the exact role that blueberries play in brain health. Studies have shown that blueberries or bioactive blueberry compounds can improve insulin sensitivity and reduce the risk of type 2 diabetes by up to 26% ( 10, 11).Ī large observational study has shown that people who eat blueberries also have slower rates of cognitive decline, meaning their brain remains healthier as they age ( 12). lowering LDL (bad) cholesterol in the bloodīlueberries may lower the risk of diabetes as well.In addition, blueberries may improve other aspects of heart health by ( 7, 8, 9): One cup (148 grams) of blueberries provides the following nutrients ( 1):īlueberries also contain antioxidant polyphenols called anthocyanins ( 2).Īnthocyanins from blueberries may reduce oxidative stress, lowering the risk of heart disease in both healthy people and those at high risk for the condition ( 3, 4, 5, 6). Blueberries are popular berries that serve as a great source of vitamin K.
