Sweet potatoes VS potatoes: which one is healthier?
When it comes to white versus sweet potatoes, is one better than the other? According to Dr Hazel Wallace, doctor, nutritionist, and founder of The Food Medic, the two spud varieties should actually be treated equally.
Health benefits of potatoes
“Both white potatoes and sweet potatoes contain vitamins and minerals, fibre and phytonutrients,” Dr Hazel explains. “Sweet potatoes, however, have an impressive amount of beta carotene, which is a precursor of vitamin A, with one standard serving offering the recommended daily intake.
Why eat sweet potatoes instead of regular ones?
Sweet potatoes have a lower glycaemic index than white potatoes. The glycaemic index, or GI, is a ranking of how quickly different carbohydrates make your blood glucose levels rise after eating them – useful information to know if you’re wondering ‘are sweet potatoes carbs?’.
“As a side note,” Dr Hazel says, “the GI has a number of shortcomings, but has been proven to be beneficial in certain populations and circumstances – for example, in athletic performance and in patients with type 2 diabetes. However, the difference between the GI of a white potato and a sweet potato is relatively small, so it’s unlikely to make a massive difference.
“Side by side, they’re both good guys, and can each make up part of a healthy diet – so, why don’t we just have both? Personally, I prefer cooking with, and the taste of, sweet potato (cover your ears, mum!). But, there are certain times when I really just want normal fries or a baked spud!”
When it comes to cooking with sweet potatoes, they can be treated very similarly to regular potatoes. If you’re wondering how long to boil sweet potatoes, they should only take about 20-25 minutes in salted water. Keep in mind that timings will vary based on the size of your potato cubes, as well as the recipe you’re making, whether it’s French fries or mash.
Roasted sweet potatoes are also a wonderful option. You can leave the skin on or peel it off, but be sure to roast them at a super-high temperature, and cut them into about 2.5cm pieces to ensure a faster cooking time. Finally, add some seasoning, or a bold punch of flavour such as harissa or chilli and cinnamon.
Sweet potato pies are a real winner in our books, and this hearty dish makes clever use of bold flavours and hearty textures. The simple sweet potato mash is flavoured with wholegrain mustard and mature Cheddar cheese. This sits atop a rich filling of vegetables, red lentils and cannellini beans for a pie that’s seriously comforting.
Smoked Greek cheese may not be the most obvious of sweet potato pairings, but it works surprisingly well in this twist on a traditional Italian dish. To make the gnocchi, simply peel off the sweet potato skin and cut the flesh into chunks. Boil for 10 minutes, drain and mash, then beat in the eggs with the cheese and flour. The gnocchi is then simply cooked in boiling water for a few minutes. Serve with a butter and sage sauce and a sprinkle of pine nuts.
