Potatoes are often equated with refined grains due to their carbohydrate content. Yet, potatoes contain fiber, resistant starch, and key micronutrients that Americans need more of in their diet.
A randomized crossover study that included 50 generally healthy adults directly compared the nutrient quality and impact on cardiometabolic risk factors of non-fried potatoes to refined grains.
The study was conducted by researchers at Penn State and was recently published in the British Journal of Nutrition. Its findings demonstrate that potatoes can support a healthy diet; daily intake of one serving of non-fried potato did not affect markers of glycemia and was associated with better diet quality compared to refined grains.
According to the Penn State researchers, “Clinical studies are important to contextualize observational findings. Some epidemiologic studies have suggested an association between potato intake and increased risk of cardiometabolic diseases. However, the context around how potatoes are eaten, such as their preparation method or other foods eaten alongside them, may be important factors in explaining why our clinical trial findings differ from those of observational studies.”
The research team further concludes that “Americans eat too many refined carbohydrates and not enough whole grains or starchy vegetables, according to the 2015-2020 Dietary Guidelines for Americans. Our study findings suggest that eating 1 serving of non-fried potatoes in place of refined grains can help individuals meet more dietary recommendations.”
