A comparison is always made between similar things. For dissimilar things all we can do is contrast. Since papaya and apple are disparate, we can only contrast their nutritional value in order to find which out of these two is healthier.
It is said that "an apple a day keeps a doctor away." There is no denying the fact that Apple is a plethora of healthy constituents such as vitamin A, vitamin C, magnesium, sodium, carbohydrate, and protein. But the amount of each of these constituents decides how healthy an apple is and how useful it is to be prevented from various diseases.
Apples are very rich in antioxidants and dietary fiber. These primarily help in reducing the risk of heart attack, diabetes, cancer, high blood pressure, liver disorders, gallstones, constipation, anemia etc.
Papaya contains vitamin A, vitamin C, magnesium and calcium, carotenes,iron in smaller quantities.
Papaya is often used in face masks and face packs. This is because papaya has antioxidants that give the skin a fresh and radiating look. The enzyme papain in papaya aids digestion, which prevents constipation. It is great for your eyes and also protects you from arthritis.
Papaya and apple both are healthy but they should be eaten with care. Apple can be eaten by anybody (any age group), but papaya should not be consumed by pregnant women. Also, these fruits must be consumed fresh.
