  • First-Take phytochemical quiz- we will take the
    same one at the end and see if you learned
    anything!
  • Then-Take a few minutes and jot down some foods
    you think might contain phytochemicals.

3
  • Americans do not eat enough fruits and

  • Do we need yet another reason to eat fruits and
    vegetables?

4
  • Phyto- Greek word for plants
  • Substances in plants that may help prevent
    diseases like cancer and heart disease.
  • So far, scientists know of 3,000 different
    phytochemicals with possible health benefits.

5
  • Definitions you may need to know
  • Free radicals- are byproducts of metabolism. They
    are capable of causing cells to lose their
    structure, function and eventually destroying
    them.
  • Connected with the development of 50 diseases
    including heart disease and cancer.

6
  • What are antioxidants?
  • Capable of stabilizing or deactivating free
    radicals before they attack cells.
  • Chemoprevention- using one or several compounds
    to prevent, stop or reverse the development of
    cancer.

7
  • Designer Food- Processed foods that are
    supplemented with food ingredients naturally rich
    in disease-preventing substances.
  • Functional Food- any modified food or food
    ingredient that may provide a health benefit
    beyond the traditional nutrients it contains.

8
  • Nutraceutical - Specific chemical compounds in
    food, including vitamins and additives, that may
    aid in preventing disease.
  • Pharmafood- Food or nutrient that claims medical
    or health benefits, including the prevention and
    treatment of disease.

9
  • A disease of the bodys cells
  • Carcinogenesis is a multistage process.
  • Initiation-transformation of cell
  • Promotion- cells multiply to form a tumor
  • Progression - Leads to a malignant tumor.

10
  • Heart Disease is a general term for a list of
    diseases affecting the heart.
  • Can be caused by a variety of factors but
    atherosclerosis and hypertension play a major
    role.
  • Is the number 1 killer in the United States.

11
  • Apparent ability to stop a cells conversion from
    healthy to cancerous.
  • Inhibit various hormone actions and metabolic
    pathways that are associated with the development
    of cancer and heart disease.

12
  • Some phytochemicals have been found to lower LDL
    cholesterol.
  • Others have been found to help prevent blood
    clotting.
  • Reduce how much cholesterol the body produces and
    keep blood pressure down.

13
  • Phytochemicals are also being used in cancer
    treatment in dosages.

    of fruits and veggies have reduced cancer risks.
    They are doing something right!!!!

    powerful as beta carotene (Vitamin A) in the
    destruction of free radicals.

17

  • They help to keep healthy cells in the body from
    being damaged by free radicals.

18
  • Grapes, Strawberries, Cranberries, Nuts,

34
  • There are some available, but remember They
    will only provide selected components in a
    concentrated form but not all of the compounds
    that occur naturally in the foods.
  • Is there a negative side?
  • Studies on animals containing large amounts of
    phytochemicals have had negative results.
  • Optimal levels of phytochemicals have yet to be
    determined.

35
  • There are things that you can do!
  • Eating a variety of vegetables and fruits.
  • Eat more grains-at least half of them whole
    grains.
  • Dont forget herbs and spices,
  • Decrease portion size of meats.

36
  • Keep fruits and vegetables stocked and in sight.
  • Reach for juice instead of coffee or soda.

    muffins, or even a milkshake.
  • Snack on fresh chopped carrots, celery, broccoli,
    cauliflower and peppers.

37
  • Add fresh greens, carrots, celery, parsley,
    tomatoes, and beans to your soups.
  • Store dried fruit (apricots, dates, raisins)
  • for a quick snack at home or work.

38
  • Using the color wheel hand-out, determine how
    many phytochemicals are in the meal below
  • Tomato Soup and crackers
  • Fruit salad ( pineapple, strawberries, peaches,
    and cherries)
  • Grilled cheese - made with low-fat cheese
  • Glass of Water

39
  • The answer is 9!
  • Tomato Soup- lycopene, phytoene, phytofluene, and
    Vitamin E.
  • Pineapple and peaches - Vitamin C and Flavonoids
  • Strawberries and cherries - anthocyanins ,
    Ellagic Acid and Flavonoids.
  • Remember- This is only the main class of
    phytochemicals, there are many more than this!

  • Phytochemicals are a complicated topic! To
    uncomplicate thisyou have a project on
