Powerful antioxidant, antitumor and cardioprotective action, helps in case of joint pain and irritable bowel syndrome, anxiolytic properties.
It was an apple that caused the war between Greeks and Trojans, it was an apple the fruit of immortality that Hercules managed to steal from the garden of the Hesperides and it was always an apple that, according to legend, fell on Newton's head, inspiring the great scientist the theory of gravitational force. The apple has always been a symbol of beauty and eternal life but it is not just about myths and traditions, this fruit is truly a precious source of beneficial substances for health contained in the pulp but above all in the peel. Unfortunately, we are often used to throwing away the apple peel, thus losing important nutrients. So let's see what science says.
Apple peel, properties
Apple peel is a valuable source of antioxidants, such as phenols and flavonoids. It has been observed that the amount of antioxidants present in the apple peel is higher than that contained in the pulp. Not only that, the peel of the apple more than any other part of the fruit also exhibits anticancer properties. For example, it has been shown to inhibit a type of liver tumor. In particular, among the varieties analyzed by the study, the Rome Beauty apple was the one with the greatest antitumor capacity, inhibiting up to 50% of the proliferation of diseased cells (Wolfe et al, J Agric Food Chem, 2003). The polyphenols of apple peel have also been shown to reduce chronic inflammation with benefits both in the intestine, helping in case of irritable bowel syndrome, and in the joints in case of pain, decreasing the pain and improving the mobility (Jensen et al, J Med Food, 2014). And that's not all, in fact, given the higher amount of antioxidants present in the peel, this part of the apple demonstrates a more powerful cardioprotective action than the pulp. Both apple pulp and peel, indeed, help to keep blood pressure and cholesterol under control, counteract the formation of atherosclerotic plaques, improve endothelial function, which is the lining of blood vessels and the heart, and decrease insulin resistance but, with regard to all these properties, the peel of the apple has proved more effective than the pulp (Tian et al, Clin Exp Hypertens, 2018 - Gonzalez et al, Evid Based Complement Alternat Med, 2015). Therefore, as we have seen, not discarding the peel of the apple but eating it together with the fruit is certainly a very healthy choice. However, in this case, it is preferable that the apple is organic, in fact the pesticide levels are higher in the skin and in the core than in the pulp (Kong et al, Food Addit Contam Part A, 2012). In addition, the apple, even organic, should always be well washed, like any fruit.
Apple herbal tea
But apple peel is not only a rich source of antioxidants, in fact, it also provides substances, such as bromide, with a calming and anxiolytic action (Aufiero, The nutritional and therapeutic role of foods). To benefit from the sedative effect of the apple, we can prepare ... an apple tea. Wash an apple well, possibly organic. Peel the apple. Bring a cup of water and the apple peel to a boil and simmer for five minutes, then remove from heat and filter. You can sip in the evening.
