Although there is no food that starts with the letter "x" in the English language, "xigua" is a Chinese word for watermelon and was the original name for the food. The xigua is a melon with powerful health benefits and there are more than 1,200 different varieties of the sweet watermelon worldwide.
A watermelon's nutritional value is found mostly in the rind. In fact, 95 percent of the nutritional value is found in the rind and the white parts of the melon so it makes a great juicing ingredient for those who like to juice. Watermelons help to keep skin fresh and the body hydrated as well as cleaning out the kidneys of toxins. Watermelons are great for eyesight because they contain a lot of vitamin A and for brain power as they contain a lot of vitamin B6.
Wild watermelons first originated in southern Africa and can be classified as both a fruit and a vegetable. The watermelon, or xigua, is considered a fruit because it grows from a seed. However, it is also a vegetable because it comes from the same family as the pumpkin, squash and cucumber. It is also harvested from fields like other vegetables.
