alcohol and body
Higher levels of folic acid and, probably also, of vitamin B6 in the plasma should reduce the risk of breast cancer. Such the conclusion of the authors of a study conducted in Harvard University.
Folate and folic acid are water-soluble forms of vitamin B. They occur for instance in yeat extract and in spinach. Dr. Feigelson and his associates researched the data of a large-scale American breast cancer research for indications that the increased risk of breast cancer due to alcohol consumption can be reduced by an appropriate intake of folate.
The researchers looked for possible relations between (i) breast cancer, alcohol consumption and intake of and (ii) multivitamin preparations.
The connection between breast cancer and alcohol was confirmed. The risk was 26% higher among women in the top category of alcohol consumption (15 g or more alcohol per day) than among total abstainers. No link was found between the risk of breast cancer and the intake of folic acid or the use of multivitamins.
However, experts from Harvard University did conclude around the same period that a higher concentration of folic acid in the plasma, and probably also vitamin B6, can reduce the risk of developing breast cancer. This may be of particularly great importance for women who are more prone to breast cancer on account of alcohol consumption.
