Blueberries are abundant in vitamin C and other antioxidants; the potassium in bananas supports cardiovascular health, and the bromelain found in pineapples is an enzyme that helps with digestion. Cherries, especially tart ones, ease the pain of arthritis, treat insomnia and guard against gout and belly fat.
The antioxidants found in blueberries guard the cells of the body against injury by free radical molecules, and the hefty dose of vitamin C in the berries is also a powerful antioxidant. Blueberries are also low in calories.
The abundant potassium found in bananas guards against high blood pressure and hardening of the arteries. The plant sterols in bananas also support heart health and help to block cholesterol. Bananas are also good sources of water-soluble fiber. The fiber also helps the banana maintain a low glycemic level even though it is famously sweet when ripe. Fiber slows down the rate of digestion, and so the rate of sugars and carbohydrates entering the blood stream is also slowed down.
The bromelain in pineapples not only helps digestion but fights inflammation and blood coagulation. It has even been shown to have anti-tumor properties. Like blueberries, pineapples are also full of vitamin C and other antioxidants. These antioxidants protect against macular degeneration. Manganese and vitamin B1 are also present in pineapples.
