Many people think that consuming well balanced diet gives all the vitamins and proteins required for a good health.

Both of these result in larger than usual food element size, too large to permit full action of digestive enzymes. Many people with dentures are not capable to chew as powerfully as those with a full set of real teeth.

It could as well damage the lining of the intestinal area and could have other adverse affect the absorption of nutrients, cause to sub-clinical malnutrition. Alcohol affects accessibility, incorporation and metabolism of nutrients. Regular use of alcohol increases the body's requirements for the B-group vitamins, chiefly thiamine, niacin, pyridoxine, folic acid and vitamins B12, A and C plus the minerals zinc, magnesium and calcium.

Bizarre diets that miss out on complete groups of foods could be gravely lacking in vitamins. Even the accepted low fat diets, if taken to a tremendous, could be lacking in vitamins A, D and E. Vegetarian diets that could keep out meat and other animal sources, have to be very dexterously planned to avoid vitamin B12 deficiency that may further lead to anemia.

Some antibiotics even though expensive in fighting infection, as well kill off friendly bacteria in the gut that would usually be producing B-group vitamins to be engrossed through the intestinal walls. Such deficiencies could result in a variety of nervous conditions, so it might be sensible to use supplement with B-group vitamins when on a lengthy course of broad range antibiotics.
