Adequate vitamin D levels may reduce frailty risk

Higher serum levels of the main circulating form of vitamin D, 25-hydroxyvitamin D (25(OH)D), are associated with substantially lower incidence rates of colon, breast, ovarian, renal, pancreatic, aggressive prostate and other cancers, as suggested by a new publication.
The authors combined epidemiological findings with newly discovered mechanisms suggesting a new ‘seven phase’ model of cancer development: disjunction, initiation, natural selection, overgrowth, metastasis, involution, and transition. Vitamin D metabolites are thought to prevent disjunction of cells and are beneficial in other phases.
As suggested by the researchers, an increase of the minimum year-round serum vitamin D level from 40–60 ng/mL (100–150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three-quarters of deaths from these diseases in the United States and Canada, based on observational studies combined with a randomized trial.
“The time has arrived for nationally coordinated action to substantially increase intake of vitamin D and calcium”, the authors added. (1)

Metabolic processes that occur in the presence of oxygen, innate immune defense processes and external factors lead to the formation of so-called reactive oxygen species, (ROS), the ‘prooxidants’ that oxidize lipids, DNA and proteins and can impair their functioning. A sufficient intake of plant-typical ingredients with ‘antioxidant’ activity appears to play an important role in preventing degenerative diseases like cardiovascular disease and some kinds of cancer. Prominent among these substances, which the human organism cannot synthesize for itself, are the carotenoids, vitamins C and E, and the flavonoids.

A new UK study suggests that a rare genetic variant causing reduced levels of vitamin D may be directly linked to multiple sclerosis.
