What they're good for:
Helps wounds heal, strengthens blood vessels, builds connective tissue,
healthy gums, skin and promotes strong teeth and bones. May boost
immunity. What they're good for:
Supports bones, teeth, muscle tissue, regulates the heartbeat, muscle
action, nerve function, blood clotting. What it is: A
unit of measure, like an inch or a pound. Calories measure the amount of
energy your body gets from food. You need energy to be physically active
and for your body to grow and function.
Carbohydrates,
fat and
protein provide the energy from food. What it is: The
body's most readily available source of energy. Each gram of carbohydrate
provides 4 calories of energy. The main forms of carbohydrate are sugars
and starches. Sugars are simple carbohydrates. Starches, such as breads,
cereals and pasta, are complex carbohydrates. Detailed information can be
found
here. What they're good for:
Makes cell membranes, hormones. Low-density lipoprotein (LDL) is often
called "bad" cholesterol because too much in your blood can cause heart
disease. High-density lipoprotein (HDL) is often called "good" cholesterol
because it helps remove LDL . What they're good for:
Acts cooperatively with other substances to control insulin and certain
enzymes. Tidbit:An organic
non-protein molecule that binds with the protein molecule to form the
active enzyme. Several
vitamins are components of coenzymes. Tidbit: Coenzyme R
denotes biotin. What they're good for:
Co-enzyme Q10, also known as ubiquinone, improves energy production within
the heart and acts as an antioxidant. Patients with congestive heart
failure, hypertension and angina show lower levels of CoQ-10 than those
with no cardiovascular disease. It prevents lipid oxidation occurring in
fat-soluble media such as cell membranes and is useful in the treatment of
high cholesterol, high blood pressure and congestive heart failure. It is
sometimes proposed as a complementary therapy to combat AIDS-related
conditions. Tidbit: Inorganic
complement of an
enzyme reaction, usually a
metal ion. What they're good for:
Formation of red blood cells, pigment, bone health. What they're good for:
Calcium and phosphorus metabolism, aids bone growth and integrity,
promotes strong teeth. Dietary Reference Intakes:
A joint collaboration with Canada and the US, DRIs are revised
recommendations for vitamins and minerals from the Institute of Medicine,
an arm of the National Academy of Sciences, which will gradually replace
the Recommended Dietary Allowances or RDA guidelines. DRIs are being
developed for vitamins and minerals that currently have no RDAs. What they're good for:
Antioxidant powers protect cell membranes, essential for red blood cells,
aids cellular respiration and protects lung tissue from pollution. What they're good for:
Make cell membranes, hormones, and prostaglandins. What it is: A
concentrated energy source. Fat provides 9 calories per gram, more than
twice as much energy as protein and carbohydrate. Fat also provides
essential fatty acids, is an important component of cell structure, and
transports vitamins A, D, E and K. What they're good for:
Lowers cholesterol and blood sugar levels, helps move waste through the
intestines. Diets rich in plant fiber are related to a reduction of heart
disease, colon cancer and diabetes. What they're good for:
Discovered only in 1945, this B VITAMIN is used by the body both to
synthesize and break down
AMINO ACIDS and to synthesize
DNA/RNA-like nucleic acids, which in turn are needed to build new
cells, especially new red blood cells. Its role in preventing two
devastating birth defects — spina bifida (a condition in which the
backbone doesn't envelop and protect the spinal cord) and anencephaly (a
fatal malformation of the brain) — is so significant the FDA, to ensure
that pregnant women receive sufficient folacin, aims to add it to the list
of nutrients now being used to enrich flours, cereals, breads and pastas
(140 micrograms folacin per 100 grams [3 1/2 ounces] food is the proposed
amount). In addition to preventing these birth defects, folic acid may
also protect against certain types of cancer (lung, cervical, colorectal)
and coronary heart disease. Even so, nutritionists recommend getting folic
acid from food, not vitamin pills. There is some concern, however, that
too much folacin masks pernicious anemia and makes it difficult to
diagnose. What they're good for:
Helps cells grow and divide, reduces risk of certain birth defects,
important for red blood cells and crucial in creating amino acids. What they're good for:
Dental health. Tidbit:Vitamin F
refers to the Essential
Fatty Acids, or EFAs. These are still accepted as being required by
the human body, but are no longer denoted as a vitamin. The FDA outlawed
this terminology when fast-food chains started claiming "vitamin enriched
foods" based on the fact that frying food in oil adds EFAs.
