CLINICAL UPDATE - Why fish oils work swimmingly against diabetes

Researchers at the University of California, San Diego School of Medicine have identified the molecular mechanism that makes omega-3 fatty acids so effective in reducing chronic inflammation and insulin resistance.

CLINICAL UPDATE - Low b vitamin status raises cancer risk

An eight year study which measured the level of four B vitamins – B2 (riboflavin), B6 (pyridoxine), B9 (folate) and B12 (cobalamin) – on more than 500,000 people showed that lower levels of B vitamins increased the risk of lung cancer, in both smokers and non-smokers.

CLINICAL UPDATE - Evidence mounts for the gene-nutrient theory of disease

Mounting research supports the idea that micronutrients affect gene expression and conversely that individual genes affect the levels of micronutrients needed by individuals. Investigation into specific genes for vitamins C, D and E strongly support the notion that biochemical individuality profoundly impacts micronutrient status.

CLINICAL UPDATE - levels of coq10 in mom affects infant birth weight

Levels of the lipid-soluble antioxidant coQ10 were measured in 50 healthy pregnant women at each trimester.  Results showed that levels of maternal coQ10 is positively associated with fetal growth, especially in the third trimester.

CLINICAL UPDATE - more reasons why omega 3 fatty acids are critical in pregnancy

Five year old children whose mothers received DHA versus placebo while breastfeeding scored higher on a test of sustained attention.  In a recent animal study, researchers found that healthy omega 3 fatty acid status during pregnancy protected offspring from neonatal brain injuries.

CLINICAL UPDATE - study supports prostate cancer benefits of tocotrienols

The link between Vitamin E and cancer benefits has received extra backing from a new study, which found that a mix of different forms of the vitamin helped prevent prostate tumor growth in mice.

CLINICAL UPDATE - vitamin C improves mood

In a double-blind clinical trial, mood was assessed with a standardized test on hospitalized patients that were given 500mg of vitamin C and 1000 IU of vitamin D twice daily.  Vitamin C levels were associated with a 34% reduction in mood disturbance  while no effect was seen for vitamin D levels.
