Did you know that: It's often said that eating an apple a day keeps the doctor away. And this is very true - apples are a mine of vitamins, fibre and other nutritional substances strengthening the immune system. They're a treasure-trove of monosaccharides, which quickly permeate the blood and act as an energy booster for your tiring organism. Fruit carries a unique combination of vitamin C and P, as well as magnesium, that makes blood vessels more flexible and tight, warding off sclerosis.
