There is one finding from this study we’re concerned is being taken out of context, and that has to do with starchy vegetable intake. Researchers concluded that “Limiting added sugar, sugar-sweetened beverages, refined grains, and starchy vegetables in favor of whole grains, fruit, and nonstarchy vegetables may support efforts to control weight.”
But not all starchy veggies should be demonized or even avoided.
Potatoes, peas, and corn are (at their core) nutritious foods. They all offer some fiber and micronutrients like potassium and carotenoids (like beta-carotene and lutein). And they can even be a source of resistant starch if you cook and then cool them before eating.
The kicker here is how they’re processed and consumed. And in this study, it was noted that the majority of this starchy veggie intake came from potatoes.
Past research tells us that most potato consumption in the United States comes in the form of French fries, potato chips, or mashed potatoes (likely served with other high-calorie foods, like butter, cheese, or sour cream).
So it’s likely safe to infer that the connection between starchy vegetable intake and weight gain in this study is driven most by consumption of processed or fried potatoes.
