With a lower GI than potatoes, sweet potatoes are an excellent source of beta-carotene, which the body converts into vitamin A — an antioxidant that supports healthy skin, immune health and vision.
But despite their name, they aren’t part of the potato family.
For a sweet potato and swede mash, simmer peeled, sweet potatoes and swede until soft.
Drain and leave to steam in a colander (so that the end result is not too watery) before returning them to the pan to mash with a little olive oil, salt and pepper.
Try zesting in a little lemon or orange for a zap of citrus to match the bright orange colour.
You can also roast the vegetables before mashing them.
This gives a rich taste, but be aware that it may raise the GI because, compared to boiling, roasting causes water loss and degrades the starches.
