Vitamin A is a fat-soluble vitamin that
is frequently accompanied in nature by vitamin
D. A good food source of vitamin A contains a substantial
amount of vitamin A and/or carotene, which is naturally converted
into vitamin A in the body.
Increased beta-carotene levels seem to decrease the chance of
developing lung cancer, a noteworthy effect for cigarette smokers
or those regularly exposed to second hand smoke. Individuals
with a low intake of beta-carotene have a 30% to 220% higher
risk of developing lung cancer than persons who regularly absorb
adequate levels of beta-carotene.
