Does vitamin B reduce cancer rates?


In a study done of 5,ooo women it was claimed that vitamin B's don't reduce cancer rates. Reported by the Journal of the American Medical Association researchers found that there was little difference in the number of women who developed cancer while taking supplements compared to the women that were taking the placebo. It was suggested that women should focus on heating healthy, exercising and quitting smoking to prevent cancer rather than relying on supplements.

The researchers analyzed the data form women who were 42 and older and had a pre-existing heart disease or carried three or more risk factors for coronary disease. The trial studied if supplements of folic acid and vitamin B6 and B12 prevented heart disease in women at high risk for the condition versus the placebo. Of the women that were given the supplement 187 developed invasive cancer compared to 192 women who took the placebo. Little difference was seen between breast cancer and deaths from cancer in either group. Of the women over 65 that took the supplements 25 percent reduction in their risk of developing cancer and a 38 percent reduction risk of getting breast cancer. It was also stated that more studies need to be done on this age group to rule out or back up the finding of this research.
If their is even a little percentage possibility that taking a supplement can help with reducing of developing cancer I would encourage people to take the supplement or make sure they are getting all of their nutrients from their food. 25 percent and 38 percent is not a lot but it is more than 0 and being efficient in vitamin b6 and b12 can have a little effect on not developing cancer. Much depends on the individual person.

Dietary intake of B-vitamins in mothers born a child with a congenital heart defect


The aim of this study was to investigate the association between the maternal dietary intake of B-vitamins and having a child with a congenital heart defect (CHD). This was a case control study that comprised of 192 mothers with children that have CHD and 216 mothers with healthy children. The mothers took a questioner that evaluated their dietary intake. Blood samples were used to determine vitamin b levels. It was discovered that education level played a large role in the amount of vitamin b the women were consuming. Mothers with low education level showed a lower vitamin b 12 intake than the controls. The CHD risk doubled if vitamin B12 intake in these mothers reduced by 50%.

The study concluded with a diet low in vitamin b12 was associated with an increased risk of a child developing CHD, especially in low educated women.

Dificiency in vitamin B12 can have some serious effects on the body

The B vitamins play a key role in maintaining good health. In the case of vitamin B 12 deficiency it can cause damage to ones functional system. It can lead to irreversible damage to the brain and nervous system. At levels that are slightly lower than normal fatigue, poor memory, and depression have all been reported as leading symptoms. It is also stated that low levels lead to mania or psychosis. If a severe shortage occurs it can lead to a serious illness called pernicious anaemia. This is when their are not enough red blood cells in the spinal cord and nerve cells begging to get damaged.


The main reason for deficiency is that the body is not absorbing it properly or people are not getting enough of it in their diet such as vegans. This can be addressed by eating foods that have the vitamin in it, supplements, or injections. Fortified foods are the most common especially cereal. The other foods are in order, pig or calf's liver, fatty fish like salmon, white fish, beef, eggs, cheese, chicken and milk.
