How do you correctly describes HDL cholesterol? - ANSWER: High levels of HDL
cholesterol are beneficial because they protect against heart disease.
How do antioxidants slow the aging process? - ANSWER: They reduce cellular
damage by binding with free radicals produced during oxidation reactions.
What is the difference in the energy content of each nutrient? - ANSWER:
Carbohydrates and protein produce 4 calories/gram and lipids produce 9
calories/gram.
What is the difference between carbohydrates and proteins? - ANSWER:
Carbohydrates consist of simple sugars and starches; proteins consist of eight
essential amino acids and 12 nonessential amino acids.

What is the benefit of eating orange vegetables such as carrots and squash? -
ANSWER: They are high in Vitamin A.
Carbohydrates - ANSWER: A nutrient that provides caloric energy. Carbohydrates are
either simple sugars, such as honey and sugar, or complex compounds derived from
cereal or potatoes.
Proteins - ANSWER: Composed of smaller structures called amino acids, 8 essential
and 12 nonessential. All amino acids are required by the body for proper nutrition.
Proteins are present in every cell, in enzymes, and in body secretions. Proteins
provide calories but also serve other important and complex functions. They help
build new cells and tissues in growing children; repair damaged tissues; maintain
tissues that are already built; and play a role in the manufacture of blood, enzymes,
hormones, and human milk.
, Lipids - ANSWER: Organic compounds that do not readily dissolve in water; based on
their solubility, they are classified into triglycerides (more commonly known as fats),
phospholipids, and sterols.
Minerals - ANSWER: These inorganic elements are present in the body in small
amounts, but they play a vital role in nutrition. The major minerals needed by the
body are calcium, phosphorus, potassium, sulfur, sodium, chloride, and magnesium.
Vitamins - ANSWER: Organic compounds required by every part of the body to
maintain health and prevent disease. They are classified as either fat-soluble or
water-soluble. Unlike minerals (such as calcium, which is integrated into bones),
vitamins do not become part of the body
Antioxidants - ANSWER: Act as scavengers by binding to free radicals, thus
preventing them from causing damage.
Triglycerides - ANSWER: The energy of these provide much of the stored energy of
the body, and the fat deposits insulate body organs against changes in
environmental temperature and protect the organs and underlying tissues by acting
as a shock absorber.
Phospholipids - ANSWER: Are an essential component of all cell membranes and thus
are ubiquitous throughout the human body.
Sterols - ANSWER: The most well known for this lipid is cholesterol, which, despite its
reputation, plays several important roles in the body.
Cholesterol - ANSWER: Is used to build cell membranes and brain and other nervous
tissue. Among other functions, this helps the body produce steroid hormones
needed for the regulation of blood sugar, salt and water balance, production of bile
acids needed for digestion, and reproduction.
