Mango

Mango is rich in vitamin C, vitamin B6 and vitamins K, A and E. Fruits like mangoes and banana are high in vitamin B6 content and are therefore good for brain health. It is erroneously believed that mango is a food source of amino acid glutamine which is involved in the production of DNA and is also responsible for determining mood and changes in sleep pattern. Glutamine is synthesized by the body from another amino acid glutamic acid with the help of vitamin B6. It is not found in food.
