Poor Digestion
Even when your food intake is good, inefficient digestion can limit your body's uptake of vitamins. Some common causes of inefficient digestion are not chewing well enough and eating too fast. Both of these result in larger than normal food particle size, too large to allow complete action of digestive enzymes. Many people with dentures are unable to chew as efficiently as those with a full set of original teeth.
Hot Coffee, Tea and Spices
Habitual drinking of liquids that are too hot, or consuming an excess of irritants such as coffee, tea or pickles and spices can cause inflammation of the digestive linings, resulting in a drop of secretion of digestive fluids and poorer extraction of vitamins and minerals from food.
Alcohol
Drinking too much alcohol is known to damage the liver and pancreas which are vital to digestion and metabolism. It can also damage the lining of the intestinal tract and adversely affect the absorption of nutrients, leading to sub-clinical malnutrition. Regular heavy use of alcohol increases the body's need for the B-group vitamins. Particularly thiamine, nicotinic acid, pyridoxine, folic acid and vitamins B12, A and C as well as the minerals zinc, magnesium and calcium. Alcohol affects availability, absorption and metabolism of nutrients.
Smoking
Smoking too much tobacco is also an irritant to the digestive tract and increases the metabolic requirements of vitamin C, all else being equal, by at least thirty per cent more than the typical requirements of a non-smoker. Vitamin C which is normally present in such foods as paw paws, oranges and capsicums, oxidises rapidly once these fruits are cut, juiced, cooked or stored in direct light or near heat. Vitamin C is important to the immune function and is a protector vitamin.
