Eating Potatoes Is Healthy

Contrary to common belief, potatoes do not have a negative effect on blood glucose levels and can actually help people lose weight, according to researchers at Louisiana State University's Pennington Biomedical Research Center.

What to Know

  • Potatoes are filled with key nutrients, packed with health benefits, and do not increase the risk of type 2 diabetes, as has been assumed.

  • People tend to eat the same weight of food regardless of calorie content to feel full, so by eating foods that are heavier in weight and that are low in calories, you can reduce the number of calories you consume.

  • Study participants found themselves fuller, and more quickly, and often did not even finish their meal when the high-calorie items of their meals were replaced with potatoes.

  • Participants had overweight, obesity, or insulin resistance, but their blood glucose levels were not negatively affected by the potato consumption, and all of those involved actually lost weight.

  • People typically do not stick with a diet they don't like or that isn't varied enough, but potatoes can be prepared in numerous ways for variety in a diet, and they are a fairly inexpensive vegetable to incorporate into a diet.
