Forest fruits are low in calories, inexpensive and very healthy. They are rich in vitamin C, magnesium, potassium and phosphorus. Soft and juicy berries, raspberries, blackberries and strawberries can be very easily blended, which is why they are an ideal ingredient for summer cocktails. In order to make their sour taste milder, you can combine them with some milk, natural yoghurt or banana. Such a liquid snack will be perfect as lunch and afternoon tea. It is best to buy forest fruits from local sellers, not in supermarkets.
