The Essential Nutrients: Thirteen Vitamins
Two Types
|
|
|
Fat Soluble
Fat soluble vitamins which include vitamins A, D, E and K are easily stored in the fatty tissues of the body and liver. Stored vitamins can act as reserves for months. Also, these vitamins are absorbed through the intestinal tract with the help of fats, or lipids.
Water Soluble
Water-soluble vitamins, which include all the B vitamins and vitamin C, do not stay in the body for long because the body cannot store them, and they are soon excreted in urine. Because of this, water-soluble vitamins need to be replaced more often than fat-soluble ones.
Thirteen, but All Necessary
Each vitamin is used in the body in specific ways. If you have low levels of certain vitamins, you may get health problems. For example, not enough vitamin C could cause you to become anemic. Not enough vitamin A could cause night blindness.
You can usually get all your vitamins from the foods you eat and your body can make vitamins D and K. People who eat a vegetarian diet may need to take a vitamin B12 supplement.

The Essential Nutrients:
Vitamin A
|
|
|
Vitamins: A, Type: Fat Soluble
Vitamin A is a group of unsaturated organic compounds that includes retinol, retinal, retinoic acid and several provitamin A carotenoids: alpha-carotene, beta-carotene, gamma-carotene; and the xanthophyll beta-cryptoxanthin.
Retinol is the form absorbed when eating animal food sources.
Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.[
Vitamin A Specifics
DV: males - 900 μg, 3000IU, ; females - 700 μg, 2310IU
Tolerable Upper Limit: adults 3000μg, 10000IU
Toxic Level: males >25,000 IU per day, females >8000 IU per day.
Benefits: healthy eyes; healthy dark vision; prevents night blindness; healthy immune system; decreased heart attack risk.
Deficiency: eye problems; night-blindness and keratomalacia, an eye disorder that results in a dry cornea; growth problems; insomnia; fatigue; reproductive difficulties.
Indication: Retinol is destroyed by light, high cooking temperatures and when using copper or iron utensils. May help prevent cataracts, age related macular degeneration. People with high vitamin A intake have fewer heart attacks and strokes.
Vitamin A is toxic in large doses and should not be taken. To avoid vitamin A toxicity, take Betacarotene instead.
Symptoms of Deficiency: abscesses forming in the ear; frequent colds and respiratory infections (asthma, hay fever, bronchitis); sinustis; and skin disorders (acne, boils, bumpy skin, eczema).
Symptoms of Overdose: Blurry vision and headache; diarrhea and vomiting; drowsiness and appetite loss; hair loss, irritability; lethargy; skin irritaions.
Sources: apricot, broccoli, butternut squash, cantaloupe melon, carrots, cod liver oil, collard greens, egg, herring, kale, liver (beef, chicken), mangoes, pumpkin, red bell pepper, salmon, spinach, sweet potato and winter squash.
Carrot, 1 med. 60g, 10,191 IU
Sweet potato, 1/2 cup 65g, 9,935 IU
Beef liver, 85g, 9000 IU
Chicken liver, 100g, 4900 IU
Egg, one large, 100 IU
Salmon, 85g, 11 IU
Note: Deficiency Indicator
If you see floaters in your eyes, then your liver is robbing your eyes of Vitamin A. You are deficient in vitamin A. Eat an organic carrot!
