A new US study suggests that higher dietary intakes of the vitamins B1 and B2 may reduce the incidence of premenstrual syndrome (PMS) by about 35 percent.

The cells of multivitamin users may have a younger biological age than cells from non-users, according to new research from the US.
The aging and lifespan of normal, healthy cells are linked to the so-called telomerase shortening mechanism, which limits cells to a fixed number of divisions. During cell replication, the telomeres function by ensuring the cell's chromosomes do not fuse with each other or rearrange, which can lead to cancer. With each replication the telomeres shorten, and when the telomeres are totally consumed, the cells are destroyed (apoptosis). Previous studies have also reported that telomeres are highly susceptible to oxidative stress .
Researchers noted that telomere length may therefore be a marker of biological ageing, and that antioxidant effects of multivitamins may beneficially affect telomere length via protection against oxidative stress and chronic inflammation. According to the epidemiologic study, the telomeres of daily multivitamin users may be on average 5.1% longer than in non-users, potentially indicating a delayed aging process (1).
However, as regular multivitamin users tend to follow a healthy lifestyle and have a higher intake of micronutrients, it is difficult to interpret epidemiologic observations on multivitamin use. Further investigations are needed to understand the role of multivitamin use and telomere length and its implication in the development of chronic diseases.

It is believed that around a third of all cancer cases could be attributed to dietary and lifestyle factors. The link between nutrition and cancer risk is very complex, and it is difficult to establish the influence of individual dietary factors. The results of reviews have indicated that cancer-preventive diets above all consist of large quantities of plant-based foods such as fruit, vegetables, whole grains and pulses. With a low energy density, these foods supply the body with plenty of fiber, as well as varying amounts of essential micronutrients such as vitamins, carotenoids, minerals and trace elements, which are thought to potentially influence the specific mechanisms by which cancers develop. Several of these micronutrients are involved in the maintenance of genetic information (Deoxyribonucleic acid, DNA) and may therefore be able to prevent the formation of tumor cells.
