Vitamin K has displayed cancer-fighting, cancer-preventing activity in various cell lines including those of prostate cancer. This is the first epidemiological study to examine a relationship between Vitamin K levels and prostate cancer incidence. Researchers from the Division of Cancer Epidemiology, German Cancer Research Centre in Heidelberg followed 11,319 men for 8.6 years on average.

Recent epidemiological studies have demonstrated that selenium may be an effective chemopreventive and anticancer agent with a broad spectrum against several human cancer cells including those of prostate, colon, bladder, lung, liver, and ovarian cancer and leukemia. A wide range of potential mechanisms have been proposed for the tumor preventing effects of selenium and these include anti-androgen activity. There is also a cancer growth inhibitory effect by regulation of p53; A gene in the cell that normally inhibits the growth of tumors - this can prevent or slow the spread of cancer.

French researchers report that two separate markers independently predict a possibility of developing dementia and having either one is risky. Researchers at INSERM in Bordeaux, France evaluated data from 1,214 participants in the Three-City Study. The subjects aged 65 or older did not have dementia upon enrollment and were observed for 4 years.

     As it turns out it is a common finding to discover damage to the meniscus when an MRI is performed on a middle-aged or elderly person. However, although there may also be knee pain, frequently the damage to the meniscus is not the cause (or at least not yet a contributor). The problem is the physician will often order arthroscopic surgery for the patient without searching for other causes for their pain; the blame is placed on the meniscus damage and a needless procedure is performed.

     Increased intake of vitamin K2 may reduce the build up of calcium plaques in your arteries. Calcium hardens the cholesterol on arterial walls into a hardened encrusted plaster and this leads to dangerous hardening of the blood vessels leading to coronary heart disease; Americas leading cause of death. A higher intake of K2, but not K1, was associated with a 20 per cent reduction in calcification of the arteries, according to findings published online ahead of print in the journal Atherosclerosis (however, do not throw the baby out with the bath water; Vitamin K1 is very important for building bone).
