growth in fat tissue. Blood glucose, triglyceride, fatty acid, cholesterol and

Model Of Cancer Development: Low Vitamin D Levels May Have Role - Science
Daily, 5/22/09 - "previous theories linking
vitamin D to certain cancers have been tested
and confirmed in more than 200 epidemiological studies, and understanding of its
physiological basis stems from more than 2,500 laboratory studies ... Vitamin D
may halt the first stage of the cancer process by
re-establishing intercellular junctions in malignancies having an intact vitamin
D receptor ... Vitamin D levels can be increased by modest supplementation with
vitamin D3 in the range of 2000 IU/day" - See

Vitamin
D Insufficiency Linked To Bacterial Vaginosis In Pregnant Women - Science
Daily, 5/21/09 - "Bacterial vaginosis (BV) is the most
common vaginal infection in US women of childbearing age, and is common in
pregnant women. BV occurs when the normal
balance of bacteria in the vagina is disrupted and replaced by an overgrowth of
certain bacteria ... Overall, women with BV had lower
serum 25(OH)D concentrations than those without
BV (P < 0.01). The prevalence of BV decreased as vitamin D concentration
increased to 80 nmol/L (P < 0.001). Compared with 75 nmol/L, serum 25(OH)D
concentrations of 20 nmol/L and 50 nmol/L were associated with 65% and 26%
increases, respectively, in the likelihood of BV. In summary, these findings
suggest that vitamin D insufficiency is associated with BV in the first 4 mo of
pregnancy. Further, poor vitamin D status may contribute to the strong racial
disparity in the prevalence of BV in US women" - See

Heart failure was also reduced by about a quarter. The reductions in disease were similar in people with and without clinical cardiovascular disease and regardless of blood pressure before treatment ... three drugs together, each at low dose to minimize side effects, could increase the preventive effect, reducing heart attacks by about 45% and stroke by about 60%" Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

polyunsaturated fatty acids are negatively associated with obesity - Br J
Nutr. 2009 May 19:1-5 - "Plasma fatty acid composition
was determined by GC. BMI, waist circumference
and hip circumference were inversely correlated with
n-3 PUFA, EPA and DHA
(P < 0.05 for all) in the obese group. Obese individuals had significantly lower
plasma concentrations of total n-3 PUFA, compared with healthy-weight
individuals (4.53 (sd 1.11) v. 5.25 (sd 1.43) %)"
