In an almost 30 year study, researchers found when people replace saturated fat (mainly found in meats and dairy products) with refined carbohydrates they do not lower their risk of heart disease. Those who replace saturated fats with unsaturated fats or whole grains (unrefined carbohydrate) did lower their risk of heart disease.
PositiveTip: Limiting saturated fat in the diet is still best for heart health and so are unrefined carbohydrates!
