Tips for portion control and cooking methods to maximize nutritional benefits
Portion control and cooking methods play a significant role in optimizing the nutritional benefits of sweet potatoes and supporting weight loss goals. Consider the following tips
- Mindful portions: While sweet potatoes are nutritious, they still contain calories. Pay attention to portion sizes to avoid overconsumption. Aim for one medium-sized sweet potato per serving, which is approximately 130-150 grams or about the size of your fist.
- Steaming or boiling: Steaming or boiling sweet potatoes helps retain their nutrients while minimizing the need for additional fats. This cooking method maintains the natural flavours and textures of sweet potatoes without adding excessive calories.
- Roasting with minimal oil: If you prefer a roasted texture, toss sweet potato chunks or wedges with a small amount of olive oil, then roast them in the oven. Use a light hand when drizzling the oil to minimize unnecessary calories while still achieving a crispy exterior.
- Load up on toppings: Instead of dousing your sweet potatoes with high-calorie toppings like butter or marshmallows, experiment with healthier alternatives. Try topping your baked sweet potato with Greek yoghurt, salsa, black beans, or a sprinkle of nuts for added protein, fibre, and flavour.
Other Benefits of Sweet Potato
1. Improved Vision
Sweet potatoes, particularly the darker ones such as orange and red ones get their colour from an antioxidant called beta-carotene. According to studies, beta-carotene gets converted to Vitamin A in the body and is used to form light-detecting receptors inside your eyes.
2. Anti-cancer Properties
Sweet potatoes offer an array of various antioxidants, which help protect against certain types of cancers. Studies have shown that antioxidants slow the growth of certain types of cancer cells including those of the bladder, colon, stomach, and breast.
Sweet potatoes, when boiled, have a low GI of 46. And that, too, the time of boiling affects this index. Research shows that the cooking methods can alter the structure and nature of the starches resulting in significant effects on postprandial blood glucose responses. A higher boiling period means a lower GI. Low GI means that the food takes longer to digest and thus prevents any sudden spike in blood sugar levels.
Did you know that you can consume sweet potatoes raw? Unlike regular potatoes, sweet potatoes do not contain solanine, a dangerous enzyme that potentially causes stomach pain and fever. Thus sweet potatoes can be added in small quantities to your smoothie for a quick dose of energy.
