Vitamins1

Vitamins

  • Vitamins are essential to life

  • Vitamins are required for:

    • Growth

    • Maintenance

    • Regulation of body processes


Vitamins2

Vitamins

  • Unlike carbohydrates, proteins and fats; vitamins are individual units, they are not linked together.


Vitamins3

Vitamins

  • Vitamins do not supply energy

    • However, some vitamins do function as coenzymes in the release of energy from carbohydrates, proteins and fats

  • Some vitamins available from foods in inactive forms known as precursors

    • Once inside the body, precursors are converted into an active form of the vitamin


Vitamins4

Vitamins

  • Because vitamins are organic, they can be destroyed and left unable to function

    • Heat – keep refrigerated, don’t over cook

    • Light (ultraviolet) – store in opaque containers

    • Oxygen – after cut, keep airtight

    • Some water soluble – cook with less water

  • The body needs vitamins in small amounts

    • Milligrams (mg) or micrograms (µg) instead of grams (g)

    • Although needed in small amounts, vitamins are needed on a regular basis.


Types categories

Types & Categories

  • 13 different vitamins, each with its own roles

  • Vitamins grouped into two major categories:

    • Fat-soluble (4 fat soluble)

      • Vitamin A

      • Vitamin D

      • Vitamin E

      • Vitamin K

    • Water-soluble (9 water soluble: 8 B vitamins & C)

      • Thiamin

      • Riboflavin

      • Niacin

      • Biotin

      • Pantothenic acid

      • Vitamin B6

      • Folate

      • Vitamin B12

      • Vitamin C


Write 3 facts about each

Write 3 facts about each

  • Fat-soluble vitamins

    • Found in fats and oils of foods

    • After absorbed enter lymph, then blood

    • Protein carriers for transport

    • Stored (fatty tissue/liver)

    • Doesn’t need as regularly - weekly, monthly; because stored

    • Deficiencies slow to develop; because stored

    • Toxicities more likely; because stored (mostly from supplements)

    • Precursors

    • Fecal excretion

  • Water-soluble vitamins

    • Found in watery parts of foods

    • After absorbed move directly into blood

    • Transported freely in blood

    • Not stored

    • Needed more regularly – every 1-3 days; because not stored

    • Deficiencies fast to develop; because not stored

    • Toxicities less likely (large amounts can overwhelm)

    • Usually no precursors

    • Urine excretion


Recommended consumption

Recommended Consumption

  • Consuming vitamins in the right amount is important

    • Inadequate amounts can cause harm and excessive amounts can cause harm

    • More is not better

  • Normally, a well balanced diet based on the USDA Daily Food Plan and a variety of foods will provide enough vitamins.

  • No single food can supply all the nutrients in the right amount.

  • A variety of foods is needed to have a healthy diet.

Vitamins…

  • Examples

  • What they are essential for

  • Food Sources

  • With a partner complete chart using zip lock bag full of the information!

  • Complete chart due tomorrow.


Sports nutrition vitamin project 100 points due thursday

Sports Nutrition Vitamin Project100 points/Due Thursday

  • You will be assigned a partner and a vitamin. Use the information you’ve learned in class, your textbook and research to write a song or story about the vitamin. The more information and the more creative you get with it the more points you will earn! This project will be due on Thursday, February 28. Include the vitamin name, what it is essential for and food sources. If the vitamin helps prevent anything in addition to what it is essential for include that also. This must be typed, sources cited and appropriate! You will have one class period to work on this. Have fun!
