Wild mangoes come from the foothills of the Himalayas. They are by far the most important fruit in India, and have been cultivated there for four thousand years. The arrival of the mango tree in other parts of the world was probably due to the Portuguese who carried mangoes via Goa to Africa, from where they eventually reached the New World. Mango trees are now so well established in many tropical countries that it might appear that they have always been there.

Like many tropical trees, the mango tree is multi-purpose product. Its wood is used in boat building, and its leaves can be fed to cattle. Most of the mango crop is consumed in the areas where it is grown, but in recent years mangoes have gained in popularity across the world as people in mild climate become increasingly eager to enjoy the delight of the fresh fruit.

The global market for mangoes is very profitable, and mango producers are keen to make use of the fruit's growing popularity. Modern shoppers not only appreciate the fruit's high nutritional value(the mango is a good source of vitamin A and C, protein and fibre), but also expect it to look and taste perfect. Therefore producers now select only the best quality seedlings which have the most chance of developing into good quality fruit.

Mangoes are high in fiber, thus making them very good for the heart. The high fiber content is also helps easing constipation. They have high pectin(果胶) and vitamin C content that reduces the blood cholesterol levels and serves as an immune booster. This fruit is rich in anti-oxidants, vitamins, minerals and contain an enzyme(酶) that has stomach soothing properties. These enzymes act as a digestive aid and digestive proteins.

Although the mango tree has spread from its native Himalayan foothills to the tropics, delivering the fresh fruit to the world's supermarkets presents a challenge, as it does not travel well. Producers transport the fruit by speedy but costly air freight (货运)for minimum delay rather than risk the cheaper but slower road or shipping routes which, can result in damage to the fruit.

Mangoes are usually in storage for some time after their arrival at their destination. The fruit must be kept cold, or the sweet, juicy flesh will soon become over ripe and the mangoes will be unfit for sale. Fortunately, extremely effective refrigeration is now available and this is the best way of preventing the fruit from going bad before it reaches the supermarket shelves.
