Tuberculosis

Poor nutrition and poverty contribute to the incidence of tuberculosis which is responsible for many deaths globally than any other infectious disease.

Although TB is most prevalent in the developing world, there is fresh cause everywhere.

A healthy diet plays an important role in preventing tuberculosis. In particular, eating meat and fish may be significant both for preventing the disease and in its treatment.

Research suggests that a lack of vitamin B12 increases the risk of TB. People with pernicious anemia are also susceptible to the disease. It is also known that vitamin D deficiency affects immunity to disease generally.

Eggs, oily fish and dairy foods are good sources of vitamins B12 and D. Eating plenty of these foods and also lean meat together with fresh fruits and vegetables will ensure the full complements of nutrients required.

TB is caused by a bacterium known as Mycobacterium tuberculosis. The strain causing pulmonary TB is spread through coughing and sneezing.

Symptoms range from fatigue, lack of appetite and weight loss to fever, rapid loss of weight and diminished strength, but in some cases, the infected person may show no symptoms at all.

Young unvaccinated children, elderly people and those who are undernourished or generally in poor health are the most susceptible to TB.

Treatment involves rest and medication with antibiotics which must be taken daily for six to nine months for a complete cure.

Anyone traveling to countries with a high incidence of TB should be wary of unpasteurized milk and butter since it may have come from cows that are infected with a bovine strain of the bacterium.
