Lemon peel gives you clear skin
Time to roughage it. To get the most out of these 5 fruit and veggies you need to ditch the peeler.
Lemon Add citrus peel to cakes, smoothies or salads for a zesty hit of antioxidants. It’s great for getting things moving in the morning - and since studies link constipation to a spotty complexion, it can do wonders for your skin. Lemon peel is also rich in d-Limonene, which can inhibit breast cancer.
Sweet Potato The skins are packed with beta-carotene, which is converted to vitamin A in the body. One serve of sweet potato - with the skin on - provides more fiber than a bowl of porridge, plus folate and vitamin C. Try this delicious Stuffed Superfood Sweet Potato.
Kiwi Try whizzing up a whole kiwi in a smoothie - like Natasha’s Perfect Green Smoothie. The furry exterior contains three times the antioxidants of the pulp, and can fight off bugs – like staphylococcus and e-coli- responsible for food poisoning.
Apple For a perfect winter treat - try this apple fritter recipe; the ursolic acid in the peel will help offset the calories. Ursolic acid has been shown to increase brown fat, which in turn speeds up your calorie burn. Apple skin also contains quercetin, which protects your memory as well as compounds called triterpenoids, which may keep skin cancer at bay.
Cucumber Time to get used to the slightly bitter flavour; cucumber skin contains collagen-building silica. Five milligrams per day is the recommended intake – the amount you will get in the peel of one cucumber.
