Nearly every healthy diet around the world is centered on a foundation of colorful produce. To see how eating more plant foods relates to obesity risk, scientists analyzed the diets of 16,000 healthy (non-obese) adults in Spain. Those eating the most plant-based diets (high in fruits, vegetables, grains, nuts, olive oil, and pulses, and low in meat, dairy, seafood, and other animal products) had a 43% lower risk of becoming obese throughout the 10-year study than those with the most animal-based diets, even after controlling for age, physical activity, and other demographic factors. (Note that findings presented at meetings are typically viewed as preliminary until they’ve been published in a peer-reviewed journal.)
