A high-quality diet that is either low in carbohydrates or low in fat may lower the risk of cardiovascular disease. Some reports suggest that consuming a moderate amount of carbohydrates could also be beneficial for heart health. However, there is some uncertainty, as one outlet reports that low-carb diets may actually increase the risk of heart disease, while others indicate that the quality of the diet is more important than whether it is low-carb or low-fat.
