Cholesterol is a waxy, fat-like substance made by your body. It also is found in foods made from animals, like meat and dairy. Fruits and vegetables do not contain cholesterol. There are two types of cholesterol: HDL, or "good" cholesterol, and LDL, or "bad" cholesterol. Higher levels of total cholesterol and LDL or "bad" cholesterol raise your risk for heart disease. Almost half of American women have high or borderline high cholesterol.
Try not to think of certain foods as “off-limits.” When you ban certain foods, it’s natural to want those foods more, and then feel like a failure if you give in to temptation. Start by reducing portion sizes of unhealthy foods and not eating them as often. As you reduce your intake of unhealthy foods, you may find yourself craving them less or thinking of them as only occasional indulgences.
There are thousands of dietary supplements on the market, including 40+ essential nutrients alone and in various combinations, i.e. vitamins, minerals, trace elements and fatty acids. However, a number of other nutrients are "conditionally essential", meaning that the body normally can make these molecules, but some people do not make optimal amounts. Examples are L-carnitine, alpha-lipoic acid, the methyl donor betaine,  chondroitin sulfate, coenzyme Q10, choline, amino acids such as tyrosine or arginine, and "essential" sugars normally formed in the body. 
As continual research on the properties of supplements accumulates, databases or fact sheets for various supplements are updated regularly, including the Dietary Supplement Label Database, Dietary Supplement Ingredient Database, and Dietary Supplement Facts Sheets of the United States. In Canada where a license is issued when a supplement product has been proven by the manufacturer and government to be safe, effective and of sufficient quality for its recommended use, an eight-digit Natural Product Number is assigned and recorded in a Licensed Natural Health Products Database. The European Food Safety Authority maintains a compendium of botanical ingredients used in manufacturing of dietary supplements.
For example, while increased consumption of fruits and vegetables are related to decreases in mortality, cardiovascular diseases and cancers, supplementation with key factors found in fruits and vegetable, like antioxidants, vitamins, or minerals, do not help and some have been found to be harmful in some cases. In general as of 2016, robust clinical data is lacking, that shows that any kind of dietary supplementation does more good than harm for people who are healthy and eating a reasonable diet but there is clear data showing that dietary pattern and lifestyle choices are associated with health outcomes.
