Foreign scientists have conducted scientific work on the effect of wild blueberries on heart health and metabolism. The results turned out to be impressive: 1 small berry can improve the functioning of the whole body, and also has a positive effect on beauty. The journal “Critical Reviews in Food Science and Nutrition” (18+) spoke in more detail about the study.
Benefits of wild blueberries for the body
Wild blueberries are a valuable source of antioxidants, vitamins B, C and PP, as well as iron and magnesium. These microelements slow down skin aging, strengthen hair and nails, increase stress resistance, support heart function, improve vision and aid digestion. That's why blueberries are often used not only for beauty, but also for disease prevention.
How to eat blueberries correctly:
The berries are eaten fresh, frozen, added to yoghurts, cereals, and made into fruit drinks, jam and tea. The greatest benefit from the berry is fresh.
Effect on blood vessels, heart and intestines
Many studies show that after eating blueberries, blood vessels become more elastic and respond better to stress. This effect is sometimes noticeable within a few hours after a serving of berries, and with regular use – after weeks or months.
For people at increased risk of cardiovascular disease, regular consumption of blueberries can help lower blood pressure, sugar and cholesterol levels. After a few weeks of use, the subjects noted a decrease in total cholesterol, “bad” LDL and triglycerides.
In addition, blueberries are rich in fiber and polyphenols. These substances are partially absorbed only in the intestines, where they are processed by beneficial bacteria. In one study, taking wild blueberry powder daily significantly increased the number of Bifidobacterium.
Blueberries and vision: is there an effect?
Blueberry extract is widely known in ophthalmology. It really helps a lot, but you shouldn’t expect “eagle vision”, as the manufacturers of dietary supplements promise.
As Olga Arisheva, candidate of medical sciences, previously reported for KP.RU (18+): blueberries improve blood circulation in the retina and reduce the risk of retinal detachment – this is where its benefits for the eyes end.
Who should avoid wild blueberries?
Important: people with allergies to berries, prone to constipation or suffering from kidney stones, as well as exacerbations of gastrointestinal diseases blueberries are contraindicated. Caution is needed when taking antiplatelet drugs and in people with diabetes. It is recommended that you consult with a specialist.
