Diets high in sugar make your liver synthesize more LDL cholesterol. They also lower your HDL cholesterol and raise triglycerides. Try to limit desserts, candy, fruit juices, soda, sugary cereals and flavored yogurts, canned and package products with added sugars. Substitute with more beneficial sources such as fruits, raw honey, unsweetened drinks, plain oatmeal and products with wholesome ingredients.
