Eating walnuts early in life might lead to healthier habits and better overall health later in life. In a new study published in Nutrition Metabolism and Cardiovascular Diseases, researchers at the University of Minnesota used health and diet data from over 3,000 people between the ages of 18 and 30, followed for more than 30 years. They found that those who ate walnuts on a regular basis had higher physical activity levels, gained less weight, and had better overall diet quality years later than did those who did not eat walnuts. Walnut eaters also tended to eat less red meat, refined grains, added sugars, and saturated fats later in life.
