Apple is delicious and useful as it reduces the risk of colon cancer, lung cancer and prostate cancer and decreases fatty liver, obesity and glucose intolerance diseases. As for its eye protection function, I assume that apples are great for our eyes due to its high contents of Vitamin A according to recent studies. Scientists have found that lower levels of circulating vitamin A in our body are associated with eye dryness and damages to our nails, hair and skin. As our body needs some trace elements to regulate and control our circulation, we must take in enough fruits and vegetables. As the common saying: " an apple a day, keep doctor away". By the way, I like eating apples very much.
