For most of us, fruits and veggies fall in to the “healthy” category and despite whatever diet we may be on, fruits and veggies don’t count, right? Well, new research has shown that certain starchy fruits and vegetables can lead to weight gain. Shocked? You aren’t alone.

The study included more than 133,000 adults and was conducted by researchers form Harvard University. Those who ate an extra handful of blueberries actually lost weight over a four-year period while the other fruits that also helped weight loss included apples, pears, strawberries and grapes.

In addition to weight loss, fruits and veggies have also been associated with a lower risk of cancer and cardiovascular disease. As you can see, fruits and veggies do a lot of good, but if you are consistently choosing starchy ones, you might see an increase in weight gain.

On the other hand, those who ate an extra serving of corn daily over a four-year period actually gained weight.

So what exactly are “starchy” veggies and fruits? Think of veggies like potatoes, corn and peas. Anything that is a high-carbohydrate plant food is high in energy but may also be stored. Non-starchy vegetables are those that are high in vitamins, minerals and antioxidants and lower in carbohydrates. These type of veggies, are associated more frequently with weight loss.
