As the old saying goes, "An apple a day keeps the doctor away," which highlights how much people cherish apples. Right now, it's the season when local apples are flooding the market, and many people are buying them in large quantities to bring home. However, when it comes time to eat, some people feel conflicted: they worry about peeling the apple to avoid losing nutrients, yet they also fear eating the skin due to concerns about wax and potential harm. Experts have provided clarity on whether the wax on an apple is actually safe to consume.
The skin of an apple is more nutritious than the flesh. There are countless apple varieties available—such as crispy Fuji, sweet Guoguang, soft banana apples, and even imported snakefruit shipped from afar. With so many options, it's natural to wonder which one is the most nutritious. According to Dr. Fan Zhihong from the Department of Food and Nutrition at China Agricultural University, while there are many types of apples, their nutritional value is generally similar. The best choice depends on personal preference and taste.
The debate over whether to peel an apple or eat it with the skin has been ongoing for years. From a nutritional standpoint, eating the apple with the skin is definitely the better option. This is because the skin contains more nutrients and has stronger antioxidant properties, which can help prevent chronic diseases like high blood pressure.
There are three types of wax found on apple skins. First, apples naturally produce a thin layer of fruit wax, which acts as a protective barrier against pests and chemicals. Second, some premium apples are coated with edible wax made from chitosan, derived from crustacean shells. This type of wax is harmless and helps keep the apple fresh during long-distance transport. To remove this wax, simply rinse the apple with hot water. The third type of wax that should be a concern is industrial wax used by unscrupulous sellers. These waxes may contain harmful substances like mercury and lead. To check if an apple has industrial wax, try rubbing it with your hand or a napkin. If a red residue appears, it’s likely not safe to eat.
When selecting apples, look for those that have been bagged during growth, as this reduces pesticide exposure and ensures cleaner, more uniform skin. In autumn, fresh apples are widely available without preservatives, making them safer to eat with the skin. Fresh apples often have a natural white frost on their surface, which is a sign of quality. However, if the apple looks overly perfect or is out of season, it might be better to peel it before eating. Apples can last 7–10 days in a cool place, and even longer if stored in a plastic bag in the refrigerator—but this may lead to nutrient loss.
Additionally, apples have a unique ability to ripen other fruits. Placing unripe kiwifruit or pears in a plastic bag with an apple can speed up the ripening process due to the ethylene gas released by the apple. However, if you store apples with already ripe fruits or vegetables, it may cause them to spoil faster, so it’s best to keep them separate.
