Explain cholesterol

a compound of the sterol type found in most body tissues, including the blood and the nerves. Cholesterol and its derivatives are important constituents of cell membranes and precursors of other steroid compounds, but high concentrations in the blood (mainly derived from animal fats in the diet) are thought to promote atherosclerosis.

Foods high in cholesterol

High cholesterol foods include eggs, liver, fish, fast foods, butter, shellfish, shrimp, bacon, sausages, red meat, cheese, and pastries. The current daily value (DV) for cholesterol is 300mg.

Complete Protein

The main difference between complete and incomplete proteins is that complete proteins contain all essential amino acids your body requires daily, and incomplete proteins only contain some essential amino acids. Sources of Complete Protein Animal sources of protein are complete proteins, and some plant foods contain all essential amino acids. Sources of complete animal proteins include milk, yogurt, cheese, meat, poultry, fish, seafood and eggs. Soy protein is a plant-based source of high-quality, complete protein. Grains that contain all essential amino acids and are complete proteins include quinoa and amaranth, according to the Academy of Nutrition and Dietetics. Sources of Incomplete Proteins With the exception of the complete plant-based proteins previously mentioned, other plant proteins are incomplete because they provide some, but not all, essential amino acids. Incomplete proteins are found in most grains, nuts, seeds, nut butters, green peas and legumes (such as lentils, chick peas, black beans, pinto beans and navy beans).

Describe vitamins and minerals and their importance

Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.

Amino Acids

Amino acids An amino acid is any molecule that contains both amino and carboxylic acid functional groups. Amino acid is any one of a class of simple organic compounds containing carbon, hydrogen, oxygen, nitrogen, and in certain cases sulfur. These compounds are the building blocks of proteins


Carbohydrates are one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs.

Explain water and its importance

Water as a Transporter: Once a substance is dissolved in water, water becomes very important for transporting it throughout the body. Blood, which is 83 percent water, transports oxygen, CO2, nutrients, waste products, and more from cell to cell. Urine is also mostly water.
