Note: Do not tilt your head back. This may cause blood to run down the back of your throat, and you may swallow it. Use your thumb and forefinger to firmly pinch the soft part of your nose shut. The nose consists of a hard, bony part and a softer part made of cartilage.
Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body. The fat soluble vitamins are soluble in lipids (fats).
Vitamin C, as most of the vitamins, is soluble in water; one of the few vitamins that is not soluble in water is the vitamin D, which is fat soluble. The melting point of vitamin C is 190 Â°C (374 Â°F), which means the temperature at which you boil the vegetables cannot destroy the vitamin C.
