significance" - See

It has some other unexpected, physiological effects. It increases the activity of the sympathetic -- fight or flight -- nervous system, which raises alertness, blood pressure and energy expenditure ... We had to unlearn the idea that water had no effect on blood pressure, which is what all medical students had been told until the last couple of years" Gender gap persists at highest levels of math and science testing, 30-year study finds - Science Daily, 7/6/10 - "boys still outnumber girls by more than about 3-to-1 at extremely high levels of math ability and scientific reasoning" Cocoa flavanols improve vascular and blood pressure measures for coronary artery disease patients - Science Daily, 7/6/10 - "The findings indicate that foods rich in flavanols -- such as cocoa products, tea, wine, and various fruits and vegetables -- have a cardio-protective benefit for heart disease patients ... The study found a protective effect from a cocoa drink with 375 mg of flavanols, but according to researchers, a standard or recommended dosage has not yet been defined to achieve optimal health benefit ... In the current study, the benefit seen from the two-fold increase in circulating angiogenic cells was similar to that achieved by therapy with statins and with lifestyle changes such as exercise and smoking cessation" Antioxidants do help arteries stay healthy - Science Daily, 7/5/10 - "Long-term supplementation with dietary antioxidants has beneficial effects on sugar and fat metabolism, blood pressure and arterial flexibility in patients with multiple cardiovascular risk factors ... receive either antioxidants or placebo capsules for six months. Tests at the beginning of the trial, after three months and at the six month mark revealed that the patients in the antioxidant group had more elastic arteries (a measure of increased cardiovascular health) and better blood sugar and cholesterol profiles" High fructose diet may contribute to high blood pressure, study finds - Science Daily, 7/1/10 - "people who consumed a diet of 74 grams or more per day of fructose (corresponding to 2.5 sugary soft drinks per day) had a 26%, 30%, and 77% higher risk for blood pressure levels of 135/85, 140/90, and 160/100 mmHg, respectively. (A normal blood pressure reading is below 120/80 mmHg.)" Vitamins B6, B12 May Protect Against Depression in Older Adults - Medscape, 7/1/10 - "Odds of depressive symptoms were 2% lower per year for each additional 10 mg of vitamin B6 and an additional 10 μg of vitamin B12"
Low
vitamin D linked to the metabolic syndrome in elderly people - Science
Daily, 7/1/10 - "vitamin D
inadequacy may be a risk factor for the
metabolic syndrome, a condition that affects
one in four adults ... Because the metabolic syndrome increases the risk of
diabetes and cardiovascular disease, an adequate vitamin D level in the body
might be important in the prevention of these diseases ... The researchers found
a 48 percent prevalence of vitamin D deficiency" - See

Increasing fertility threefold with DHEA? - Science Daily, 7/1/10 -
"women being treated for
infertility who also received supplements of
DHEA were three times more likely to conceive than
women being treated without the additional drug ... The latter group took 75mg
of the supplement daily for 40 days before starting fertility treatments, and
continued for up to five months ... In the DHEA group, there was a 23% live
birth rate as opposed to a 4% rate in the control group ... More than that, of
the pregnancies in the DHEA group, all but one ended in healthy deliveries"

Due to these events, the treatment phase of the trial was stopped"
Key
mechanism links virgin olive oil to protection against breast cancer -
Science Daily, 6/30/10 -
"virgin olive oil
is associated with higher incidences of benign breast
tumours and at the same time with a decrease in the activity of the p21Ras
oncogene, which spurs uncontrolled cell proliferation and stimulates the growth
of tumours. In addition, olive oil suppresses the activity of some proteins,
such as the AKT, essential for the survival of cells since they prevent
apoptosis, the cell's "suicide" programme. Between proliferation and apoptosis
in tumour cells, these effects tip the balance towards cell death, thereby
slowing the growth of tumours" - See

Virgin
olive oil and a Mediterranean diet fight heart disease by changing how our genes
function - Science Daily, 6/30/10 - "The first group
consumed a traditional
Mediterranean diet with virgin olive
oil rich in
polyphenols. The second group consumed a
traditional Mediterranean diet with an olive oil low in polyphenols. The third
group followed their habitual diet. After three months, the first group had a
down-regulation in the expression of
atherosclerosis-related genes in
their peripheral blood mononuclear cells. Additionally, the olive oil
polyphenols made a significant impact on the expression of genetic changes
influencing coronary heart disease. Results also showed that the consumption of
virgin olive oil in conjunction with a Mediterranean diet can positively impact
lipid and DNA oxidation, insulin resistance, inflammation, carcinogenesis, and
tumor suppression ... olive oil and a Mediterranean diet affect our bodies in a
far more significant way than previously believed" - See

A new effect of caffeine boosts performance - Science Daily, 6/29/10 - "high doses of caffeine directly increase muscle power and endurance during relatively low-intensity activities ... a caffeine dosage of 70 µM enhanced power output by ~6% during both types of activity. This effect in humans is likely to be very similar" 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):
Green Tea
Supplementation Affects Body Weight, Lipids, and Lipid Peroxidation in Obese
Subjects with Metabolic Syndrome - J Am Coll Nutr. 2010 Feb;29(1):31-40 -
"Green tea beverage
consumption (4 cups/d) or extract supplementation (2 capsules/d) for 8 weeks
significantly decreased body weight and
BMI. Green tea beverage further lowered lipid peroxidation versus age- and
gender-matched controls, suggesting the role of green tea flavonoids in
improving features of
metabolic syndrome in obese patients" -
