Tips For Cooking And Preparing Sweet Potatoes

Curious to add sweet potatoes to your daily diet but not sure how? Sweet potatoes can be boiled, baked, or fried. However, different cooking methods may affect the levels of nutrients. Here are a few things to keep in mind while cooking and preparing sweet potatoes.

  • Stick to organic produce: If you purchase sweet potatoes from an organic farm, it is safe to cook with the peel, which is rich in antioxidants. However, store-bought sweet potatoes should

    be peeled before cooking as they may be treated with dye or wax.
  • Cook them immediately after peeling: As the flesh of these tubers darken when in contact with air and moisture, it is always better to cook them immediately after peeling or chopping.
  • Boil rather than bake: Boiling sweet potatoes retains nutrients like vitamin A and beta-carotene, which benefit your health. The glycemic index of boiled sweet potatoes is lower than those that are baked or boiled, which thus prevent a drastic increase in the blood sugar levels.
  • Enjoy them with healthy fats: To reap the maximum benefits of sweet potatoes, eat them with healthy fats so that nutrients like beta-carotene can be absorbed better by the body.13

Apart from these tips, if you ever feel like munching on chips, try frying sweet potatoes and season them at home. Although frying is not the healthiest way to have sweet potatoes, you still have a better option than packed chips filled with additives.
