Unhealthy or Healthy Mashed potato? … 🥔 🍠
I often have clients telling me they’re having mashed potato, but it’s sweet potato, so that’s ok. The common perception is that white potatoes are “unhealthy” and a bad choice, whilst sweet potatoes are inherently healthier and therefore a good choice to go for.
Sweet potatoes are good – they have a lower glycaemix index than white potatoes (though it’s not actually ‘low’) which means it has a lesser impact on blood sugar levels. It’s also a great source of vitamin A, C, B6 and Potassium and also fibre.
In contrast white potatoes have a higher glycaemic index, slightly less fibre and less vitamin A but are also good sources of Vitamin C and B6. But they aren’t unhealthy.
Despite the higher glycaemic index it’s not the individual foods that matter in that context but rather the glycaemic index of the whole meal so it will depend what you’re eating with the potatoes. Combined with other low GI foods, protein and fats the overall GI of the meal will be lowered.
In addition, as you can see, when made with exactly the same recipe the mashed sweet potatoes actually contain more calories, carbs and fat than white potatoes. So from a fat/weight loss perspective – when it comes down to calories you’d be marginally better off having white potatoes.
So if you’ve been tucking in to sweet potatoes thinking they’re better for weight loss then perhaps think again. In reality the difference is pretty small, and the calorie impact is fairly similar.If you prefer the taste then definitely go for the sweet potatoes – just have the potatoes you actually enjoy!
