Sweet Potatoes Are Diabetic Friendly

According to a research survey conducted by former Good Housekeeping Nutrition Director, Delia Hammock MS, RD, sweet potatoes are a smart choice for those on diabetic diets. While the word sweet might be a scary word for those watching what they eat, you can ease up on this naturally sweet vegetable and cozy up to some flavorful dishes.

"Sweet potatoes, despite their name, have a medium to low glycemic index, so they produce smaller blood glucose and insulin fluctuations in the body," says Hammock. "I recommend eating sweet potatoes raw in salads and slaws, or cooked and eaten with the skin for the lowest glycemic impact and for additional nutrients."

Believe it or not, sweet potatoes can be eaten raw. The flavor is not as sweet as cooked, but it is certainly refreshing and healthy. You can dip sweet potato slices into your favorite dressing, grate them into your daily green salad or turn them into a slaw, like in this recipe:

In this month's issue of Weight Watchers magazine, sweet potatoes are featured as a "food with benefits". They highlight the fact that sweet potatoes have fiber, which is another reason they are suitable for diabetics. A study published by The New England Journal of Medicine found that a high-fiber diet lowered cholesterol, triglyceride, glucose and insulin levels. Keep 'em comin'!


Here's a diabetic-friendly recipe that takes full advantage of the sweet potato's nutrients and still allows you to have an after dinner treat.

Sweet Potato Biscotti
