Cholesterol is a lipid essential for producing hormones and takes two forms: LDL, or bad cholesterol, and HDL, good cholesterol. LDL (low-density lipoprotein) contributes to plaque, which can clog arteries and increases the risk of strokes and heart attacks. HDL (high-density lipoprotein) removes LDL from the arteries and carries it to the liver to be broken down.
Lipids are essential for a healthy, balanced diet. They provide energy and also play a key role in the production of hormones and cell membranes, as well as in the absorption of nutrients and fat-soluble vitamins.
Carbohydrates are composed of carbon, oxygen and hydrogen, and are divided in 4 groups: oligosaccharides (glycose), monosaccharides and disaccharides which are sugars and serve as a quick source of energy, while polysaccharides, like starches serve for storing energy.
Vitamin A is a fat soluble vitamin that comes in various forms. It is primarily important in maintaining healthy vision and the development of bones, soft tissues and skin. IU (International Units) is the unit of measurement that almost all food labels use.
Vitamin A is a fat-soluble vitamin that is primarily important for maintaining healthy vision. It also acts as an antioxidant and is important for the health of teeth, bones, soft tissues and skin. RAE (Retinol Activity Equivalent) is the unit of measurement the scientific community prefers.
