Vitamins: Nutritional Essentials
Although the U.S. has the most plentiful food supply in the
world, it's sometimes difficult to get all of the nutrition our
bodies need. Our hectic lifestyles cause us to eat out more and
buy more prepared foods to eat at home. We eat fewer fresh
fruits and vegetables and a greater quantity of nutritionally
deficient snack and fast foods than did our parents' generation.
To ensure that we're consuming all of the nutrition our bodies
need, it's often wise to take a vitamin supplement. Vitamins can
fill in the nutritional gaps and shore up our immune systems and
stamina. Some vitamins and minerals even act as weight loss
pills, by stimulating the body's fat-burning mechanism.
Although it's ideal to consume vitamins through the foods you
eat, vitamin supplements can serve to bridge the gap and provide
a safety net for those times when you have to grab a bite on the
run.
According to the National Institutes of Health, thirteen
vitamins are essential for our bodies to function: A, C, D, E, K
and the eight B vitamins. Here's the lowdown on eleven of the
essentials:
Vitamin A is important for vision, reproductive function, and
normal cell reproduction. Beta-carotene, a precursor to Vitamin
A, helps to fight disease-causing free radicals. Vitamin A is
found in milk products, organ meats, and fish oils.
Beta-carotene is found in colorful vegetables, such as carrots,
broccoli, spinach, and sweet potatoes.
Vitamin B-1 (thiamin) processes carbohydrates into energy and is
necessary for nerve cell function. Breads and cereals are often
fortified with thiamin, though it is also found in whole grains,
fish, lean meats, and dried beans.
Vitamin B-2 (riboflavin) helps the production of red blood cells
and is important for growth.
Vitamin B-3 (niacin) helps control cholesterol, processes
alcohol, maintains healthy skin, and converts carbohydrates to
energy.
Vitamin B-5 (pantothenic acid) serves several bodily functions,
such as converting fats to energy and synthesizing cholesterol.
Vitamin B-6 (pyridoxine) is important in the production of
hormones such as serotonin, dopamine, and melatonin, as well as
for processing amino acids.
Vitamin B-12 is a crucial component of DNA replication and nerve
cell regulation. It is found in milk products, poultry, meat,
and shellfish.
Vitamin C is important in wound healing and acts as an
antioxidant. It also helps the body absorb iron. It's found in
citrus fruits, potatoes, and greens.
Vitamin D helps the body absorb calcium, which creates healthy
bones and teeth. The body can synthesize Vitamin D after
exposure to sunshine, but it can also be found in fortified milk
products and cereals, as well as in fish.
Vitamin E helps to combat free radicals, which can damage our
cells. It's found in nuts and seeds, green leafy vegetables,
corn, asparagus, and wheat germ.
Vitamin K is what makes the blot clot. While our bodies produce
some Vitamin K, it can also be found in vegetables like
cauliflower and cabbage.
