Mangos taste so good that people forget they are also healthy. Research has shown that antioxidant compounds found in mangoes have been found to protect against colon, breast, leukemia and prostate cancers. Mangoes also contain very high levels of fiber, pectin and vitamin C which help to lower cholesterol levels, specifically Low-Density Lipoprotein, while promoting a healthy digestive track. Mangoes are one of the few fruits that can be used both internally and externally for the skin. They clear clogged pores and eliminate pimples. In addition to all the great benefits that mangoes possess it is also interesting to note that one cup of sliced mangoes supplies 25 percent of the needed daily value of vitamin A, which promotes good eyesight and prevents night blindness and dry eyes.
