Vitamin B
B vitamins are water-soluble vitamins with important roles in metabolism. They are also needed for the synthesis of red blood cells. Though they share similar names, they are chemically distinct. This allows them to co-exist in foods. These vitamins - Vitamin B - have a long history in the human diet and are essential for the development of a healthy immune system. In the human body, B vitamins are found in red meat, dairy products, eggs, and green vegetables.
Vitamin B12
Studies have shown that
vitamin B12 is essential for mental health. According to the National
Health and Nutrition Examination Survey, older adults have a higher risk of
suffering from depression when their serum vitamin B12 concentration is
low. For this reason, they should increase their vitamin
B12 intake through fortified foods and supplements. For this
purpose, they can choose low-calorie cereals. A diet rich in protein is a
better choice than a low-carb diet, which may contain a large percentage of
carbohydrates.
Research has revealed
that high-levels of vitamin B12 may increase the risk of cancer.
However, the evidence is mixed. In addition, high-levels of vitamin B12
are associated with an increased risk of cardiovascular disease, dementia, and
esophageal cancer. In one meta-analysis, 18 randomized controlled trials that
included 74,498 people showed no link between high levels of vitamin B12 and
breast cancer.
