A vegetable is an edible plant which does not

It can come from many different parts of the plant.

What is a Vegetable? We will use the consumer definition.

For example:

What nutrients do they contain? Most are low in calories and fat. High in vitamins – especially A and C

A and C

Vitamin A Vitamin A is a fat soluble vitamin. Because excess can be stored in fat

you need only to eat a good source every other day.

There is a pigment in orange, dark yellow and dark green vegetables that is called Carotene. Your body uses half of it to make Vitamin A and discards the other half.

What does Vitamin A do? It helps your eyes with night vision and

adjustment. Essential in cell formation and stimulates growth.

It is the “beauty” vitamin…Helps to give shiny hair, smooth skin, etc.

History of Vitamin A First vitamin actually discovered.

During the war children in Denmark were having trouble with their vision.

Doctor thought it might be related to diet. Did some experiments with rats.

Found that adding fat to their diet cured their vision problems. (Vitamin A is a fat soluble vitamin

Denmark had been selling the cream (or fat) off their milk to other countries to help finance the war effort. Putting the cream back into the milk cured the children.

ALSO…Night blindness

Fishermen off the coast of Newfoundland were having trouble with night blindness.

Night blindness is a condition where your eye does not produce enough visual purple for you to see in the dark.

The fishermen found that when they ate the livers of the fish they were catching their night blindness was cured. There is vitamin A in Cod liver oil.

2. Reduce water

3. Reduce amount of heat and amount of time cooked.
