A Vegan Diet Improves Insulin Resistance in Just Two Days

A new randomized crossover trial looked at the effect of a vegan diet compared to an omnivorous diet in 30 healthy, older adults. When the participants ate the vegan diet, they had significantly lower insulin levels and improved insulin resistance compared to the omnivorous diet. The vegan diet also resulted in significantly lower blood sugars and markers of inflammation, all within just 48 hours.1 Previous research has also shown rapid improvements in insulin sensitivity with vegan diets.2
