Folsom, Calif., (February 9, 2016) - A new study published in the Journal of the American Heart Association found that a diet containing unsaturated fats, such as those found in walnuts and olive oil, has similar weight loss effects as a lower fat, higher-carbohydrate diet.1 The research, led by Dr. Cheryl Rock of the University of California, San Diego School of Medicine, also showed that a diet containing walnuts, which are primarily comprised of polyunsaturated fats, positively impacts heart health markers, such as cholesterol.
