If you're like most kids, you've probably heard at least one parent say,
"Don't forget your vitamin!" "Eat your salad - it's packed with vitamins!" But
what exactly are vitamins?
Vitamins and minerals are substances that are found in foods we eat.
Your body needs them to work properly, so you grow and develop just like you
should. When it comes to vitamins, each one has a special role to play. For
example:
- Vitamin D in milk helps your bones.
- Vitamin A in carrots helps you see at night.
- Vitamin C in oranges helps your body heal if you get a cut.
- B vitamins in leafy green vegetables help your body make protein and
energy.
Vitamins Hang Out in Water and
Fat There are two types of vitamins: fat
soluble and water soluble. When you eat foods that
contain fat-soluble vitamins, the vitamins are stored in the
fat tissues in your body and in your liver. They go and wait around in your body
fat until your body needs them.
Fat-soluble vitamins are happy to stay stored in your body
for awhile - some stay for a few days, some for up to 6 months! Then, when it's
time for them to be used, special carriers in your body take them to where
they're needed. Vitamins A, D, E, and K are all fat-soluble
vitamins.
Water-soluble vitamins
are different. When you eat foods that have water-soluble vitamins, the vitamins
don't get stored as much in your body. Instead, they travel through your
bloodstream. And whatever your body doesn't use comes out when you urinate.
So these kinds of vitamins need to be replaced often
because they don't like to stick around! This crowd of vitamins includes vitamin
C and the big group of B vitamins - B1 (thiamin), B2 (riboflavin), niacin, B6
(pyridoxine), folic acid, B12 (cobalamine), biotin, and pantothenic
acid.
Vitamins Feed Your Needs Your body is one powerful machine, capable of doing all sorts of
things by itself. But one thing it can't do is make vitamins. That's where food
comes in. Your body is able to get the vitamins it needs from the foods you eat
because different foods contain different vitamins. Though some kids take a
daily vitamin, most kids don't need one if they're eating healthy
foods.
Now, let's look more closely at vitamins - from A to
K:
Vitamin A This vitamin plays a really big part in eyesight. It's great for
night vision, like when you're trick-or-treating on Halloween. Vitamin A helps
you see in color, too, from the brightest yellow to the darkest purple. In
addition, it helps you grow properly and aids in healthy skin.
Which foods are rich in vitamin A?
- eggs
- milk
- apricots
- nectarines
- cantaloupe
- carrots
- sweet potatoes
- spinach
The B Vitamins There's more than one B vitamin. Here's the list: B1, B2, B6, B12,
niacin, folic acid, biotin, and pantothenic acid. Whew - that's quite a group!
The B vitamins are important in metabolic (say:
meh-tuh-bah-lik) activity - this means that they help make
energy and set it free when your body needs it. So the next time you're running
to third base, thank those B vitamins. This group of vitamins is also involved
in making red blood cells, which carry oxygen throughout your body. Every part of
your body needs oxygen to work properly, so these B vitamins have a big job.
Which foods are rich in vitamin B?
- whole grains, such as wheat and oats
- fish and seafood
- poultry and meats
- eggs
- dairy products, like milk and yogurt
- leafy green vegetables
- beans and peas
- citrus fruits, such as oranges
Vitamin C This vitamin is important for keeping body tissues, such as gums and
muscles in good shape. C is also key if you get a cut or wound because it helps
you heal. This vitamin also helps your body resist infection. This means that even
though you can't always avoid getting sick, vitamin C makes it a little harder
for your body to become infected with an illness.
Which foods are rich in vitamin C?
- citrus fruits, like oranges
- cantaloupe
- strawberries
- tomatoes
- broccoli
- cabbage
Vitamin D No bones about it . . . vitamin D is the vitamin you need for strong
bones! It's also great for forming strong teeth. Vitamin D even lends a hand to
an important mineral - it helps your body absorb the amount of calcium it needs.
Which foods are rich in vitamin D?
- milk and other dairy products fortified with vitamin D
- fish
- egg yolks
Vitamin E Everybody needs E.
This hard-working vitamin maintains a lot of your body's tissues, like the ones
in your eyes, skin, and liver. It protects your
lungs from becoming damaged by polluted air. And it is important for the
formation of red blood cells.
- whole grains, such as wheat and oats
- wheat germ
- leafy green vegetables
- sardines
- egg yolks
- nuts
Vitamin K Vitamin K is the
clotmaster! Remember the last time you got a cut? Your blood did something
special called clotting. This is when certain cells in your blood act like glue
and stick together at the surface of the cut.
Which foods are rich in
vitamin K?
- leafy green vegetables
- liver
- pork
- dairy products, like milk and yogurt
When your body gets this vitamin and the other ones it needs, you'll be
feeling A-OK!
