Apples are a popular fruit, containing antioxidants, vitamins, dietary fiber, and a range of other nutrients. Due to their varied nutrient content, they may help prevent several health conditions. They also provide an array of antioxidants. These substances help neutralize free radicals. Free radicals are reactive molecules that can build up as a result of natural processes and environmental pressures. If too many free radicals accumulate in the body, they can cause oxidative stress, and this can lead to cell damage.
