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

  8. 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.

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. 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

  12. ALSO…Night blindness Fishermen off the coast of Newfoundland were having trouble with night blindness.
