Plant-based diets have proven effective at reducing heart disease markers in adults, but with a large proportion of overweight and obese children, experts wonder if dietary interventions are effective on kids as well. In a small study in the Midwestern US, twenty-eight overweight and obese children (average age = 15) and their parents were assigned to either a plant-based vegan (no animal products at all), no-added fat diet (with only moderate avocado and nuts) or an American Heart Association diet (high in fruits, vegetables, and whole grains, but also includes low fat dairy, some plant oils, lean meat and fish, and permits some refined grains) for four weeks. The plant-based group significantly improved nine different risk factors of heart disease (including improved blood pressure, cholesterol, and weight), while the American Heart Association Diet significantly improved four risk factors.
