Is This the Unhealthiest Vegetable Ever? Harvard Scientists Say Yes

Most nutrition experts agree that vegetables are among the healthiest foods you can eat. While they're crucial for a balanced, nutrient-dense diet, a study by the Harvard T. H. Chan School of Public Health suggests that not all vegetables are nutritionally equal. In fact, its findings suggest that one type of vegetable might actually lead to weight gain.

Every four years, Harvard researchers ask approximately 130,000 adults to share a detailed food diary, SheFinds reports. Participants are asked to chronicle what they eat every day for one week, as well are their weight. So far, this study has been running for more than 20 years, giving researchers detailed data about the link between daily diet and weight—and the exact foods that might make it hard for you to stay in shape. 

According to the study, one type of vegetables leads to weight gain: starchy foods. Theses ingredients have higher glycemic loads, which can cause a spike in blood sugar levels, causing you to want to eat more. 

Corn was found to be the worst offender, followed by potatoes and peas. "Corn was the worst, with two pounds of weight gained for every additional serving over four years," SheFinds reports. 

That doesn't mean you should stop adding it to your salads though. Corn is high in other vital nutrients and should be eaten as part of a balanced diet. As always, the age-old wisdom of everything in moderation rings true. 

Have you removed starchy vegetables from your diet? Did you notice a difference in your health or weight?
