Bilberries may slow down glucose digestion and reduce glucose and insulin spikes following a carb-rich meal. Therefore, bilberries may be useful for metabolic syndrome and type 2 diabetes prevention. Imbalances in blood sugar regulation and high-sugar diets are associated with an increased risk of obesity, type 2 diabetes, and heart disease.
Chronic disease prevention
Bilberries contain antioxidants. They reduce inflammation and oxidative stress, known as risk factors of chronic diseases, such as heart disease, diabetes, obesity, and cancer.
Bilberries contain anthocyanins, which may improve vision, particularly night vision. They reduce eye dryness and other symptoms of eye fatigue. They also have been shown to help the eyes by lowering the blood and fluid pressure and, possibly, reducing the likelihood of cataracts.
Bilberries have antibacterial against potentially harmful bacteria, such as Salmonella and Staphylococcus aureus.
Bilberries contain antioxidants, which may affect areas of the brain essential for intelligence, memory, and cognitive performance. They decrease oxidative stress, which may negatively affect the nervous system.
Improve brain function
Bilberry consumption can lower heart-related death risk, improve blood antioxidant status, decrease oxidative stress, reduce inflammation, improve vascular function, improve blood lipid profile, and reduce the harmful oxidation of LDL cholesterol.
