Tamarind

Tamarind is a fruit which grows in Asia and Africa.
This sour fruit that you will probably find dried at your local store is a great source of antioxidant.
As so, it helps in cancer prevention.
Tamarind contains vitamin C, carotene and B vitamins. It is also a very good source of  Iron, magnesium, phosphorus, protein and potassium. It helps reduce fever, and is also known for its laxative virtues. It is indeed very effective in helping the digestive system, and fighting constipation.
The B vitamins helps the nervous system, while the magnesium keeps the bones strong. The potassium ( higher than in bananas) helps controlling the blood pressure.
Tamarind has a high sugar and calories level, therefore, it is not recommended in diabetics diet.
You can buy tamarind sweets ( tamarind rolled in balls with sugar) in some store, or you can make your own tamarind juice by letting the dried fruit sleep in water for a night, and adding sugar if you wish.
