I’ve always known sweet potatoes are good for us, but do you know just how good they are for us?
In terms of nutritional value, sweet potatoes are much better for us than the white potato. They have a distinct thin brown skin on the outside, with a coloured flesh inside, and can be eaten peeled or whole, as the leaves of the plant are edible too. Other varieties of include purple, yellow and white.
Sweet potatoes are rich in fibre and also contain different vitamins and minerals including selenium, iron and calcium. They’re also a good source of vitamin B and vitamin C. Sweet potatoes are high in an antioxidant known as beta-carotene, which converts to vitamin A once it has been consumed. Just 80g of sweet potato counts towards one of our five-a-day.
Whilst there are no single ‘superfoods’ that can prevent cancer, there is widespread evidence to suggest that eating a healthy diet can reduce the risk of cancer. Studies have also suggested that antioxidants found in the peel of sweet potatoes, in particular the purple sweet potato may help reduce the oxidation process, thereby reducing the risk of cancer.
Fruit and vegetables are also high in antioxidants, compounds that help defend the body from ‘free radicals.’ Another study in Asia also found that diets including vitamin A, including the sweet potato may also provide protection from lung cancer.
It’s our job to make sure that our lifestyle and diet contribute to our wellness, however we manage to achieve it.
