If your exposure to sweet
potatoes is limited to your favourite restaurant's healthier potato option,
now's the time to open your eyes to the weight-loss wonders of the tuber. Here
are three reasons sweet potatoes help you drop pounds.
They're naturally sweet: No refined sugar overload here — sweet
potatoes make for a healthy, lower-calorie treat. Satisfy any morning
sweet/salty cravings with sweet potato apple pancakes, and get your
healthy dessert fill with sweet potato desserts.
They regulate blood sugar: Sweet potatoes may have their fair share of
carbs (about 33 grams per cup), but they contain a compound that increases
levels of adiponectin, the blood-sugar regulating hormone, in the body. Sweet
potatoes have a relatively low glycemic index rating (50), which can
also help prevent blood sugar spikes after you eat. Regulated blood sugar
levels can help get rid of those sugary cravings you get when your levels dip.
And while studies have been conflicting, some research has shown that
low-glycemic foods stay in your digestive tract longer, helping you control your appetite. To maintain sweet potatoes'
low-glycemic properties, boil or steam them instead of roasting them (which
destroys some of these properties).
They contain fibre: High-fibre foods are another foolproof way to
control hunger. Fibre helps you feel fuller for longer, and one medium sweet
potato (about 200 grams) contains four grams of the nutrient.
Sweet potatoes don't just help you trim your
waistline, however. They're powerful sources of vitamin A, which helps boost
immunity and promotes good eye, skin, and bone health, as well as high levels
of anti-inflammatory antioxidants. Regardless of whether you're trying to lose
weight or not, sweet potatoes' seemingly superfood status isn't a license to
order all the sweet potato fries you want — a 2011 study found that those
deep-fried sweet potato fries may not be as healthy as you think!
