Vitamins Are complex organic substances Normal growth,
maintenance, and reproduction Your body cannot produce all vitamins
you can get those by eating a nutritious diet. Fat-soluble
vitamins: carried in fatty parts of foods and dissolve in fats
(body stores them in fat... build up can be dangerous)
Water-soluble vitamins: dissolve in water (body does not store
them) www.makemegenius.com Free Science Videos for Kids

Minerals In addition to vitamins your body also needs 15
minerals that help regulate cell function and provide structure for
cells. Major minerals, in terms of amount present, include calcium,
phosphorus, and magnesium. In addition, your body needs smaller
amounts of chromium, copper, fluoride, iodine, iron, manganese,
molybdenum, selenium, zinc, chloride, potassium and sodium. Amounts
needed for most of these minerals is quite small and excessive
amounts can be toxic to your body. www.makemegenius.com Free

Water Water is your body's most important nutrient, is involved
in every bodily function, and makes up 70- 75% of your total body
weight. Water helps you to maintain body temperature, metabolize
body fat, aids in digestion, lubricates and cushions organs,
transports nutrients, and flushes toxins from your body. Everyone
should drink at least 64 ounces per day, and if you exercise or are
overweight, even more. Your blood is approximately 90% water and is
responsible for transporting nutrients and energy to muscles and
for taking waste from tissues. www.makemegenius.com Free Science
