PROPERTIES OF NIACIN OR VITAMIN B3

 

Characteristics of niacin

Problems caused by the lack of niacin

A serious deficiency of this vitamin is pronounced mainly in the form of serious alterations of the health:

- Pellagra: It is a disease produced by the lack of niacin. Until the mid-twentieth century it constituted a world-wide plague. A society that based its power on the consumption of maize, lacking tryptophan and with little niacin, developed a disease characterized by the poor condition of the skin (dark skin, dry, scaly skin with itchy feeling when you sunbathe), in addition to intestinal mucosal inflammation, diarrhea and in severe cases, dementia.

At first it was thought that this disease was caused by some kind of germ until it was discovered that had its origin in a food shortage: a lack of niacin in the diet. Today is virtually eradicated in the developed world but remains a scourge in Africa and Asia.

 

- Nerve Problems: Small deficiencies of niacin can be manifested as alterations of the nervous system, like nervousness, anxiety, depression, insomnia, irritability and, in more serious cases, in the form of dementia.

 

- Digestive Problems: The lack of this vitamin can be manifested as inflammations of the digestive apparatus that are translated in diarrhoea, intestinal malaise, indigestion, itching in the rectum, thickening of the tongue and mouth sores.

 

Niacin deficiency

A smaller deficiency is pronounced in the form of:

- Bad breath.

- General discomfort with weakness, lack of interest and indiscriminate general pain.

 

Where can it be found?

- Animal sources of niacin: The main direct source animals are beef, chicken, lamb or pork. Liver is particularly rich. The fish, especially tuna, is also a rich source.

These same sources are also rich in tryptophan from which the body produces too niacin. This component is responsible for half of our food niacin. Milk or milk products (yogurt, custard, cheese, etc..) and eggs are rich in tryptophan.

- Vegetable sources of niacin: Rich sources of niacin are: whole grains (rice, oats, wheat, etc.) and its derivatives (bread, pasta, wheat germ , etc.), peas, potatoes, artichokes, peanuts. Tryptophan-rich vegetable sources are avocados, oats and dates.

Failure to leave the treatment effect.)
