Blueberries are native to North America and are also now grown in a number of European countries, Turkey, South America, South Africa, Australia and New Zealand. They are loaded with antioxidants and other nutrients, including vitamin K, manganese, vitamin C and fiber.
One study found that consumption of blueberries by older people improved memory and slowed down or stopped the deterioration of mental processes, although participants consumed large quantities of the berries. Another study found that blueberries helped blood sugar regulation in people with type 2 diabetes.
Research has shown that eating blueberries improves antioxidant defences in the cardiovascular system, improves the nervous system, the digestive tract, and even muscle damage. Other studies have shown benefits of consuming blueberries for inflammation, depression, blood pressure and cholesterol levels. Tests on animals have shown better eye health, reduced risk of cancer, and less brain damage after stroke.
I eat a small punnet of blueberries on the weekend in breakfasts of yoghurt and other fruit.
