Among the various vitamins that are an important constituent of our diet and essential to keep the body functioning properly, vitamin B12 occupies an important place. As per the IMA, it is alarming to note that a sizeable portion of the Indian population is deficient in B12.
A prolonged deficiency of this vitamin can manifest as anemia, fatigue, memory loss, mood swings, irritability, tingling or numbness in the arms and legs, poor vision, mouth ulcers, constipation/diarrhea, neurological illnesses and infertility. However, B12 deficiency is reversible.
Deficiency of B12 is detected through blood tests such as complete blood count (CBC) and the level of vitamin B12 in the blood. The levels of folate (another B vitamin) are also usually measured for a related condition called folate deficiency anemia. Once the diagnosis is established, a person is usually referred to a specialist. For instance, hematologist for blood conditions, a gastroenterologist for digestive disorders, and a dietitian for advice on food containing more vitamin B12.”
Tips to prevent deficiency of Vitamin B12.
Consuming alcohol in excess leads to gastritis and damages the intestinal lining. This can further interfere with absorption of vitamin B12. It has been observed that serum vitamin B12 levels are usually lower in smoking. Vegetarian food is deficient in vitamin B12. Therefore, it is important for them to take a B12-containing multivitamin. Other than this include soy foods and foods fortified with vitamin B12 in your diet.
Include vitamin B6 in your diet. This will help in the absorption and storage of vitamin B12. Spinach, walnuts, poultry and avocados are good sources of B6.
