2Fruits and VegetablesA rich source of
Micronutrients
3Choose a diet with plenty of fruits and vegetables
- These foods provide the vitamins,
- minerals and fiber essential for good health.
- Dark Green Veggies contain Folic acid, Vitamin
C, Calcium and Iron. - Orange and Red Veggies high in Beta carotene,
Vitamin C and Lycopene. - Orange Colored Fruits rich in Beta-carotene,
Folic acid and Vitamin C. - Citrus Fruits and Berries excellent source of
vitamin C
4Nutritional Facts
- Dietary patterns characterized by high intakes of
fruits and vegetables are consistently associated
with significant reductions in cardiovascular
disease risk. - The results of epidemiological and controlled
clinical trials suggest that diets rich in fruits
and vegetables can help prevent bone loss. - The results of prospective cohort studies suggest
that high intakes of vitamin C- and
carotenoid-rich fruits and vegetables may be
associated with decreased risk of age-related eye
diseases, such as macular degeneration or
cataracts. - The Dietary Guidelines for Americans recommend
that adults consume 7-9 servings (3½-4½ cups) of
fruits and vegetables daily.

Vegetables Losses!Valuable Nutrients
7Micronutrients Facts
- A lot of the micronutrients in fruits veggies
are lost between the farm and your plate.The
losses that occurs are of three types. - Volatile substances
- Substance dissolved in the water discarded from
preparation and cooking - Substance destroyed by heat
- The longer the foods are stored before you eat
them,the more nutrients are lost. Heat, light and
exposure to air all reduce the amount of
vitamins,especially vitamins C,thiamin folic
acid.
8Nutritional Losses!
- Losses in Preparation
- Preparation of fruits and vegetables often
involves some loss of nutritive value. - Removal of dark green outer leaves means of loss
of vitamin A value. - Peeling before boiling increases losses of
ascorbic acid. - Cutting vegetables into pieces increases the loss
of soluble nutrients. - Cutting vegetables for salad causes loss of
ascorbic acid because of the action of enzymes.
9Nutritional Losses!
- Losses in Cooking
- During fruits and vegetables cookery, losses of
minerals and water-soluble vitamins occur. - Losses of the B-vitamins are due largely to
solution except for some heat destruction of
thiamine. - Ascorbic acid is, however, susceptible to
oxidation as well as to solution. - The calcium content of vegetables is affected by
the water in which they are cooked. - Vitamin C and Riboflavin is destroyed if heated
in the presence of an alkali (e.g. bicarbonate of
soda). - Folate is destroyed by prolonged cooking.
10Save! MicronutrientsIn Fruits and Vegetables
11Selection
- Fruits and vegetables should be chosen carefully.
- Purchase it in their prime (morning).
- Damaged, wilted, and bruised fruits veggies
should be avoided, as they are likely to be waste
and loss of nutrients. - Leaf veggies should be crisp, firm,and of a good
color. - Root veggies should be firm and free of spade
marks. - Insects or mould infected fruits veggies should
be avoided.
12Storing
- The fruits and veggies should be given attention
as soon as they come into the kitchen. - Examined carefully and any braised leaves or
defected portions should be discarded. - Thoroughly washed to remove all sand soil.
- They lose vitamin C water rapidly during
storage and should be stored for the minimum time
in a clean, dry and cool place at low
temperature. - All fruits veggies should be used as soon as
possible.
13Washing
- Wash the fruits veggies thoroughly in clean
cold water. - Handle gently, a small amount at a time.
- Wash it before cutting, but do not soak them in
water, as this will cause water soluble
micronutrients to be lost. - Wash green leafy veggies in large amount of
water, lifting it up and down in water. Wash two
or three times till dirt and gritty material get
removed.
14Cutting
- If they requires peeling, peel it very thinly, as
there are nutrients under the skin. - Young potatoes, carrots, and other veggies often
do not require peeling and can be served with
their skin on. They should be scrubbed thoroughly
beforehand, to remove chemicals. - To prepare green leafy vegetables cut off roots,
remove coarse stems and undesirable leaves. - Prepare just before cooking to prevent the
destruction of vitamins by enzymes. - Always use sharp knife for cutting.
- Do not cut them in very small pieces. By
minimizing the surface area of food, fewer
vitamins are lost when exposed to air.
15Cooking
- It is better if fruits and vegetables such as
lettuce, radishes, carrot, peppers, apples,
bananas cauliflowers are eaten raw, as relishes
or in salad. - Cook the vegetables in the minimum amount of
boiling water. Placing them in boiling water
destroys enzymes, so helps to preserve the
vitamins.they should be cooked for the minimum
time, with a lid on the pan. - Cook green colored vegetables un covered, at
first, to allow volatile acids to escape. - Cook strong flavored vegetables uncovered.
- When vegetables are just tender, they should be
drained served immediately. If kept hot, there
will be further losses of vitamin C. - Use the cooking water from vegetables to prepare
soups and gravy.

17Conservation Methods of Cooking
- Baking.
- Panning.
- Steaming.
- Cooking with skin on.
- Microwave cooking.
- Microwave cooking pressure-cooking under steam
are two of the best ways to preserve micro
nutrients because these methods need minimal
water and cooking time. Other methods that help
safeguard nutrients in foods are stir-frying and
steaming with a small amount of water.
18Conclusion
- Build A Healthy Base. For A Healthy Life Style
- Enjoy a variety of foods to assure a well
balanced diet. - Choose a variety of fruits and veggies daily (4-7
servings), as it is a rich source of
micronutrients. - Studies shows, diet rich in fruits and vegetables
can help prevent bone loss,risk of age related
eye diseases, and reduction in cardiovascular
disease risk. - But! Micronutrients are very sensitive nutrients,
they are lost in water, heat and air. - From preparation to cooking , often involves some
loss of nutritive value.
19Conclusion
- In order to save nutrients
- Fruits and vegetables should be chosen carefully.
- Wash well, leave edible skins or peels.
- Serve raw fruits and veggies whole or cut up in
salads, side dishes, or for snacks and juices
when possible. - When cooking fruits and vegetables be sure to
keep their shape, texture, flavor, and color. - Steaming, micro waving and stir frying are good
choices to retain nutrients when cooking. - Using a small amount of water and a lid to reduce
cooking time. - Keep liquid used in cooking to add to soups and
gravies for added nutrients. - Don't overcook fruits and vegetables. Cook to
tender-crisp state. - Serve immediately.
