May help improve blood sugar and insulin response

Your insulin and blood sugar levels may improve after eating berries. They may shield your cells from high blood sugar levels, aid in boosting insulin sensitivity, and lessen the blood sugar and insulin response to high-carb meals, according to test-tube and human research. It's significant that both individuals with insulin resistance and healthy individuals appear to experience these effects.

In one study, eating bread with 5 ounces (150 grams) of puréed strawberries or mixed berries reduced insulin levels by 24–26% as compared to eating the bread alone. The participants were healthy women. In addition, obese individuals with insulin resistance who drank blueberry smoothies twice daily saw higher gains in insulin sensitivity than those who drank smoothies without berries did throughout the course of six-week research.
