Like yams, sweet potatoes are also a good source of fibre and vitamin C, and contain a decent amount of iron too.
#Yams vs sweet potatoes skin
Europeans and North Americans are almost certainly most familiar with the orange Beauregard and garnet varieties, but there are also varieties that look more like common potatoes, such as the Hannah, and purple varieties, like the Okinawa, as well as outliers like the Satsuma-Ito, which has purple skin and yellow flesh. Sweet potatoes actually belong to the morning glory family – that’s right, the flowers – and there are various types of different colours across both “firm” and “soft” varieties. That’s why they generally cook quicker, caramelise better, and go limp if you try making fries with them without adding starch. Their composition of sugars and starches is quite different, which you may have noticed from cooking them. What are sweet potatoes (varieties, benefits, nutritional facts)ĭespite their name, sweet potatoes aren’t actually potatoes at all.
That makes yams a great choice to serve with meats and/or greens.
Yams contain a decent amount of vitamin C to boost your immune system, and copper, which is crucial for absorbing iron. They’re also rich in fibre, potassium and manganese, so good for digestion, metabolism, and bone and heart health. Yams are a fat-free, high-carb ingredient.
#Yams vs sweet potatoes how to
Despite their differences, all yams are incredibly starchy and, to those who know how to use them, versatile too. Yams are a member of the grass family, which might seem surprising at first, but makes sense when you consider their barky skin in comparison to other grasses like bamboo and sugarcane. They come in all shapes and sizes too, with some no larger than a small potato, while the heaviest yam on record was a whopping 130 pounds. Others look more similar to sweet potatoes, which likely explains the confusion. Some look more like the branch of a tree than a vegetable, with a thick, fibrous skin resembling bark. Yams originated in Africa, Asia and the Caribbean independently, so it may come as no surprise to hear that they can vary greatly in appearance.
