• Why are vitamins essential nutrients? (p. 8)
Vitamins are essential nutrients because they assist other nutrients (e.g. the release of energy
from carbohydrates, lipids, and proteins) in completing other processes (e.g. digestion,
absorption, metabolism, and excretion).
- Since vitamins aid in assisting other essential nutrients in the body,
vitamins:
have an indirect role as catalysts for the body’s use of nutrients
are REQUIRED for regulating body processes- each vitamin serves a specific
function r/t regulation
assist in other processes by aiding growth and repair of body tissues
• What are phytochemicals and why are they valuable?
o Phytochemicals are nonnutritive plant substances that have been indicated to have
possible disease-fighting properties. (p. 105)
o Phytochemicals are valuable because they may assist in preventing or treating chronic
diseases (E.g. Diabetes, CAD, cancer, HTN, osteoporosis, arthritis, neural tube defects)
- By ingesting a variety of adequate amounts of whole foods (E.g. fruits, vegetables,
processed foods), these beneficial plant substances can aid in improving overall
immune function, more readily get rid of cancer-inducing substances, decrease
cholesterol levels in the blood, and reduce the spread of tumor cells in the body.
(p. 107)
- Phytochemicals are also valuable because they are easily accessible and are more
easily accessed than other preventative measures that can be associated with high
healthcare costs and/or medications → can have an extremely valuable role in
disease prevention.
• What are the water-soluble vitamins?
o Water-soluble vitamins are one of the two classes of vitamins (that are divided by
solubility- the other being fat-soluble vitamins). (p. 10)
o Water soluble vitamins include:
- B vitamins (thiamin, niacin, riboflavin, folate, cobalamin [B12], pyridoxine [B6],
pantothenic acid, and biotin)
* B vitamins function as coenzymes
* Choline is a part of a neurotransmitter and lecithin)
- Vitamin C → serves as an antioxidant & has coenzyme abilities
o What differentiates water-soluble vitamins from fat-soluble vitamins is that water-
soluble vitamins are easily absorbed into the blood circulation
- excesses are excreted
