SSRIs were overall 15 per cent more
likely to be diagnosed with cataracts or to
have cataract surgery"
Vitamin
D crucial to activating immune defenses - Science Daily, 3/7/10 -
"Vitamin D is crucial
to activating our immune defenses and that
without sufficient intake of the vitamin, the killer cells of the immune system
-- T cells -- will not be able to react to and fight off serious infections in
the body" - See
vitamin D at Amazon.com.
Ritalin
boosts learning by increasing brain plasticity - Science Daily, 3/7/10 -
"Ritalin
boosts both of these cognitive abilities by increasing the activity of the
neurotransmitter dopamine deep inside the brain.
Neurotransmitters are the chemical messengers neurons use to communicate with
each other. They release the molecule, which then docks onto receptors of other
neurons. The research demonstrated that one type of dopamine receptor aids the
ability to focus, and another type improves the learning itself"
Low
levels of vitamin D linked to muscle fat, decreased strength in young people
- Science Daily, 3/6/10 - "A ground-breaking study
published in the March 2010 Journal of Clinical Endocrinology and Metabolism
found an astonishing 59 per cent of study subjects had too little
Vitamin D in their blood. Nearly a quarter of the group had serious
deficiencies (less than 20 ng/ml) of this important vitamin. Since Vitamin D
insufficiency is linked to increased body fat, decreased muscle strength and a
range of disorders, this is a serious health issue ... The study by Dr. Kremer
and co-investigator Dr. Vincente Gilsanz, head of musculoskeletal imaging at the
Children's Hospital Los Angeles of the University of Southern California, is the
first to show a clear link between Vitamin D levels and the accumulation of fat
in muscle tissue -- a factor in muscle strength and overall health" - [Nutra

Drinking
sugar-sweetened beverages daily linked to diabetes - Science Daily, 3/6/10 -
"Using the Coronary Heart Disease (CHD) Policy Model, a
well-established computer simulation model of the national population age 35 and
older, researchers estimate that the increased consumption of
sugar-sweetened beverages between 1990 and 2000
contributed to 130,000 new cases of diabetes,
14,000 new cases of coronary heart disease (CHD), and 50,000 additional
life-years burdened by coronary heart disease over the past decade"
Pine bark extract may benefit blood pressure-related kidney health - Nutra
USA, 3/5/10 - "55 hypertensive patients to participate
in the randomized, controlled study. Subjects were assigned to receive Ramipril
[an
ACE inhibitor] (10 mg
per day), and 29 of these people were randomly selected to also receive
Pycnogenol (150 mg per day) ... After six
months in the Ramipril-only group the
albumin levels decreased by 26 per cent
to 64 mg per 24-hour period, while additional Pycnogenol produced levels that
averaged 39 mg per 24-hour period, equivalent to a 57 per cent decrease ...
Statistically significant decreases in patients’
blood pressure were also observed, with systolic and diastolic blood
pressures dropping by more than 30 and 8 per cent, respectively in the
Ramipril-only group, and by a further 3 to 6 per cent in the combination group
... Diastolic and systolic blood flow improved by 8 and 12 per cent, in the
combination group"

Good Diet May Aid Ovarian Cancer Survival - WebMD, 3/4/10 -
"five years, 75% of the women who ate less than one
serving a week of yellow vegetables were alive,
compared to about 82% of those who had three or more servings of yellow
vegetables a week ... When the researchers looked at red
meat lovers vs. avoiders, "we found almost a threefold risk of dying for
those women who ate four or more servings of red meat a week compared to those
who ate less than one serving per week over the 11-year study period"

3/4/10 - "by the time you reach 61 tests, there's a 95
percent chance that you'll get a significant result at random. And, let's face
it—researchers want to see a significant result, so there's a strong,
unintentional bias towards trying different tests until something pops out ...

We're so good at medical studies that most of them are wrong -
arstechnica.com, 3/3/10 - "we simply have to recognize
the problem and communicate it with the public, so that people don't leap to
health conclusions each time a new population study gets published. Medical
researchers recognize the value of replication, and they don't start writing
prescriptions based on the latest gene expression study—they wait for the
individual genes to be validated. As we wait for any sort of reform to arrive,
caution, and explaining to the public the reasons for this caution, seems like
the best we can do"
Hemoglobin A1c outperforms fasting glucose for risk prediction - Science
Daily, 3/3/10 - "Measurements of
hemoglobin A1c (HbA1c) more accurately identify
persons at risk for clinical outcomes than the commonly used measurement of
fasting glucose ... people with HbA1c levels between 5.0 to 5.5 percent were
identified as being within "normal" range ... With each incremental HbA1c
increase, the study found, the incidence of
diabetes increased as well; those at a level of 6.5 percent or greater are
considered diabetic, and those between 6.0 and 6.5 percent are considered at a
"very high risk" (9 times greater than those at the "normal" range) for
developing diabetes"
Vitamin
D lifts mood during cold weather months, researchers say - Science Daily,

Folate
intake associated with lung function, breathlessness and the prevalence of
chronic obstructive pulmonary disease - Asia Pac J Clin Nutr.
2010;19(1):103-9 - "The COPD
patients had significantly lower habitual intake of
folate (mean 231, SD 90 mug/day) than control
subjects (mean 261, SD 110 mug/day), p<0.001. Lung function measures were found
to be positively associated with dietary folate level. Reductions in prevalence
of COPD and especially breathlessness were observed, the respective adjusted
odds ratio (OR) being 0.74 (95% confidence interval (CI) 0.35 to 1.58) and 0.43
(95% CI 0.21 to 0.91) for the highest versus lowest quartile of folate intake.
The corresponding tests for linear trend were also significant (p<0.05). In
conclusion, an inverse association was evident between dietary folate intake and
the prevalence of breathlessness for Japanese adults, together with a
significant dose-response relationship for the COPD risk. Moreover, increased
folate intake might be beneficial to lung function"
Kidney flow and function in hypertension: protective effects of pycnogenol in
hypertensive participants--a controlled study - J Cardiovasc Pharmacol Ther.
2010 Mar;15(1):41-6 - "evaluated the effects of
Pycnogenol as an adjunct to
angiotensin-converting
enzyme (ACE)-inhibitor ramipril treatment of hypertensive patients
presenting with early signs of renal function
problems. One group of 26 patients was medicated with 10 mg ramipril per day
only; a second group of 29 patients took Pycnogenol in addition to the ACE
inhibitor over a period of 6 months ... Urinary albumin decreased from 87 +/- 23
to 64 +/- 16 mg/d with ramipril only. Additional Pycnogenol lowered albumin
significantly better from 91 +/- 25 to 39 +/- 13 mg/day (P < .05). In both
groups, serum
creatinine was lowered; however, only
in the combination treatment group did the effect reached statistical
significance. In both groups, CRP
levels decreased from 2.1 to 1.8 with ramipril and from 2.2 to 1.1 with the
ramipril-Pycnogenol combination; the latter reached statistical significance.
Kidney cortical flow velocity was investigated by Doppler color duplex
ultrasonography. Both systolic and diastolic flow velocities increased
significantly after 6 months medication with ramipril. The addition of
Pycnogenol to the regimen statistically significantly further enhanced kidney
cortical flow velocities, by 8% for diastolic flow and 12% for systolic flow,
relative to values found for the group taking ramipril only" - See

Improvement of postmenopausal depressive and anxiety symptoms after treatment
with isoflavones derived from red clover extracts - Maturitas. 2010
Mar;65(3):258-61 - "assigned to receive two daily
capsules of MF11RCE (80mg
red clover isoflavones, Group A) or placebo of
equal appearance (Group B) for a 90-day period ... After receiving the MF11RCE
compound the total HADS (anxiety and depression
subscale scores also) and the total SDS scores decreased significantly. This
effect was equivalent to a 76.9% reduction in the total HADS score (76% for
anxiety and 78.3% for depression) and an 80.6% reduction in the total SDS score.
After placebo, total HADS (anxiety and depression subscale also) and total SDS
scores also decreased significantly in comparison to baseline but only
equivalent to an average 21.7% decline. CONCLUSION: Red clover derived
isoflavones (MF11RCE) were effective in reducing depressive and anxiety symptoms
among postmenopausal women" - See

Sickness behavior induced
by endotoxin can be mitigated by the dietary soluble fiber, pectin, through
up-regulation of IL-4 and Th2 polarization - Brain Behav Immun. 2010 Feb 6 -
"We show that a diet rich in soluble
fiber protects mice from endotoxin-induced
sickness behavior by polarizing mice Th2 when compared to a diet containing only
insoluble fiber. Mice fed soluble fiber became less sick and recovered faster
from endotoxin-induced sickness behaviors than mice fed insoluble fiber ...
These data show that a diet rich in soluble fiber protects against
endotoxin-induced sickness behavior by polarizing mice Th2 and promoting
alternative activation of macrophages" - See

Dietary supplementation of n-3 PUFA reduces weight gain and improves
postprandial lipaemia and the associated inflammatory response in
the obese JCR:LA-cp rat - Diabetes Obes Metab. 2009 Nov 16 -
"n-3 PUFA treatment resulted in a
significant improvement (i.e. decrease) in the postprandial response
for triglyceride (45%) (p < 0.05), apoB48 (45%) (p < 0.03) and LBP
(33%) (p < 0.05) compared to controls (measured as area under the
clearance curve). In contrast, we observed a significant elevation
in postprandial haptoglobin (165%) (p < 0.001) in obese rats
supplemented with 10% n-3 PUFA. Treatment with 5% n-3 PUFA in the
JCR:LA-cp obese animals resulted in a complementary decrease in
total body weight gain (6%) (p < 0.001) and an increase (i.e.
improvement) in adiponectin (33%) (p < 0.05) compared to controls,
without a concomitant reduction in food intake" - See

Trans-10, cis-12-conjugated linoleic acid reduces the hepatic
triacylglycerol content and the leptin mRNA level in adipose tissue
in obese Zucker fa/fa rats - Br J Nutr. 2009 Mar 19:1-13 -
"Conjugated linoleic acid (CLA) isomers have
been reported to reduce body weight and beneficially affect glucose
metabolism in animals, but the results are inconsistent and seem to
depend on animal model and type of CLA isomer. In the present study,
feeding male Zucker fa/fa rats diets supplemented with 1 % trans-10,
cis-12-CLA for 10 d reduced the liver TAG content without improving
the overall adiposity, and enhanced hepatic mitochondrial and
peroxisomal beta-oxidation ... The present results suggest that
dietary supplementation with trans-10, cis-12-CLA may increase the
catabolism of lipids in liver and adipose tissue. Moreover, we
provide new data suggesting that trans-10, cis-12-CLA modulates the
expression of resistin and adiponectin inversely in adipose tissue.
Hence, the present results suggest that trans-10, cis-12-CLA may
have some beneficial effects on lipid metabolism and adiposity but
possibly reduces insulin sensitivity" - See

placebo with 37.5 mg/day ramipril (group 2) for 8 weeks ...
Treatment with CLA significantly enhanced the reduction effect of
ramipril on systolic BP and diastolic BP (P < 0.05). It also
increased plasma adiponectin concentration (P < 0.05) and decreased
plasma concentrations of leptin and angiotensinogen (P < 0.05);

"GSE prevented in part these effects, reducing insulinemia and leptinemia by
16.5 and 45%, respectively, whereas adiponectin level increased by 61% compared
with obese controls. GSE lowered glycemia and HOMA-IR and strongly prevented
cardiac production of superoxide by 74% and NAD(P)H oxidase expression by 30%.
This is the first time that chronic consumption of grape phenolics is shown to
reduce obesity development and related metabolic pathways including adipokine

Red Wine's Resveratrol May Help Battle Obesity - Science Daily,
6/16/08 - "resveratrol inhibited the pre-fat
cells from increasing and prevented them from converting into mature
fat cells. Also, resveratrol hindered fat storage. Most interesting,
according to Fischer-Posovszky, was that resveratrol reduced
production of certain cytokines (interleukins 6 and 8), substances
that may be linked to the development of obesity-related disorders,
such as diabetes and clogged coronary arteries. Also, resveratrol
stimulated formation of a protein known to decrease the risk of
heart attack. Obesity decreases this substance, called adiponectin"

Pioglitazone Reduces ER Stress in the Liver: Direct Monitoring of in vivo ER
Stress Using ER Stress-activated Indicator Transgenic Mice - Endocr J. 2009
Sep 29 - "8 weeks of
pioglitazone treatment
reduced the accumulation of fat droplets in the liver and attenuated the
development of insulin resistance. In the liver of the ERAI transgenic mice,
ERAI fluorescence activity was clearly reduced as early as after 4 weeks of
pioglitazone treatment, preceding the improvement of insulin resistance. In
addition, after the pioglitazone treatment, serum free fatty acid and
triglyceride levels were decreased, and serum adiponectin levels were increased.
These data indicate that pioglitazone treatment suppresses ER stress in the
liver which may explain, at least in part, the pharmacological effects of
pioglitazone to reduce insulin resistance"

Plasma
Adiponectin Concentrations Are Associated with Body Composition and Plant-Based
Dietary Factors in Female Twins - J Nutr. 2008 Dec 23 -
"A significant relationship between adiponectin and 3
derived dietary patterns (F&V, dieting, traditional English), carbohydrate,
protein, trans fat, and alcohol intake was also observed. Strong inverse
associations with adiponectin were observed for BMI (-10.72%; 95% CI: -13.78,
-7.55), total (-6.89%: 95% CI: -10.34, -3.30; P < 0.05), and central fat mass
(-12.50%; 95% CI: -15.82, -9.05; P < 0.05); these relationships were significant
both when twins were analyzed as individuals and when characteristics were
contrasted within-twin pairs, suggesting a direct effect. We observed modest
associations between dietary factors and adiponectin in female twins,
independent of adiposity, and report strong inverse associations with body
composition. These data reinforce the importance of weight maintenance and
increasing consumption of diets rich in plant-based foods to prevent CVD and
type 2 diabetes"

Anti-inflammatory and cardioprotective effects of n-3 polyunsaturated fatty
acids and plant sterols in hyperlipidemic individuals - Atherosclerosis.
2008 Sep 27 - "The combination of n-3 PUFA and plant
sterols reduced several inflammatory markers. High sensitivity C-reactive
protein (hs-CRP) was reduced by 39% (P=0.009), tumor necrosis factor-alpha
(TNF-alpha) by 10% (P=0.02), interleukin-6 (IL-6) by 10.7% (P=0.009),
leukotriene B(4) (LTB(4)) by 29.5% (P=0.01) and adiponectin was increased by
29.5% (P=0.05). Overall cardiovascular risk was reduced by 22.6% (P=0.006) in
the combination group. CONCLUSION: We have demonstrated, for the first time that
dietary intervention with n-3 PUFA and plant sterols reduces systemic
inflammation in hyperlipidemic individuals. Furthermore, our results suggest
that reducing inflammation provides a potential mechanism by which the
combination of n-3 PUFA and plant sterols are cardioprotective"

greater in the telmisartan group than in the candesartan group. In vitro,
although the protein level of adiponectin was not significantly elevated, the
mRNA expression of adiponectin was elevated 1.5-fold by telmisartan in 3T3-L1
adipocytes. Our findings suggest that telmisartan may have beneficial effects in
type 2 diabetes beyond its antihypertensive effect" - I've been saying

Effect of green tea on kidney tubules of diabetic rats - Br J Nutr. 2008 Feb
6;:1-8 - "It has been documented that
green tea (GT) and its catechin components improve renal failure and inhibit
the growth of mesangial cells ... GT treatment significantly (P < 0.01) reduced
the serum glucose, glycosylated protein, serum creatinine and blood urea N
levels by 29.6 (sem 3.7), 22.7 (sem 5.2), 38.9 (sem 10) and 41.7 (sem 1.9) %,
respectively ... the GT-treated group showed a significant 44 (sem 10.8) %
higher creatinine clearance (Ccr) ... GT reduced the urea N, creatinine, glucose
and protein excretion rates by 30 (sem 7.6), 35.4 (sem 5.3), 34.0 (sem 5.3) and
46.0 (sem 13.0) % compared with the 12 weeks diabetic group. Administration of
GT to 12 weeks diabetic rats significantly (P < 0.001) prevented (99.98 (sem
0.27) % less) the accumulation of glycogen in the kidney tubules. These results
indicate that in STZ diabetes, kidney
function
appears to be improved with GT consumption which also prevents glycogen
accumulation in the renal tubules, probably by lowering blood levels of glucose.
Therefore, GT could be beneficial additional therapy in the management of
diabetic nephropathy" - See

Dietary lipoic acid-dependent changes in the activity and mRNA levels of hepatic
lipogenic enzymes in rats - Br J Nutr. 2007 Dec 7;:1-9 -
"Lipoic acid profoundly decreased serum and liver
concentrations of TAG, and also lowered serum concentrations of phospholipid and
NEFA, and the concentration of cholesterol in the liver. A hypoglycaemic effect
of this compound was also observed. Lipoic acid dose-dependently decreased the
activity and mRNA levels of fatty acid synthase, ATP-citrate lyase, glucose
6-phosphate dehydrogenase, malic enzyme and pyruvate kinase in the liver despite
that reductions were considerably attenuated in the NADPH-producing enzymes.
This compound also dose-dependently lowered the mRNA levels of spot 14,
adiponutrin, stearoyl-CoA desaturase 1, and Delta5- and Delta6-desaturases. In
addition, lipoic acid dose-dependently lowered serum concentrations of insulin
and leptin, but increased those of adiponectin. Lipoic acid appeared to reduce
hepatic lipogenesis and hence decreases serum and liver lipid levels.
Alterations in serum concentrations of insulin and (or) adiponectin may trigger
this consequence" - See

Adiponectin, the controversial hormone - Public Health Nutr. 2007
Oct;10(10A):1145-50 - "Considering the anti-inflammatory
properties of adiponectin and the fact that it is negatively associated with
adiposity, this cytokine could be one of the links between obesity and
inflammation. The main mechanisms of action of adiponectin are directed to a
protective role against atherogenic and insulin resistance processes. Research
has revealed interesting new functions far beyond metabolism, such as immunity,
cancer and bone formation. Contrary to all adipose-related proteins, adiponectin
decreases with obesity. Most of the contradictory data surrounding adiponectin
are related to plasma values and their relationship with body fat, gender
differences and insulin resistance"

Do low levels of circulating adiponectin represent a biomarker or just
another risk factor for the metabolic syndrome? - Diabetes Obes Metab.
2007 May;9(3):246-58 - "The metabolic syndrome is
currently defined by various combinations of insulin resistance, obesity,
dyslipidaemia and hypertension. The tendency for these risk factors to
appear simultaneously suggests a single aetiologic basis. A low level of
circulating adiponectin is associated with the appearance of each metabolic
syndrome risk factor ... An association between the metabolic syndrome and
low adiponectin supports the view that the development of the metabolic
syndrome may be triggered by a single underlying mechanism. Clinical studies
in the future may show that a low level of circulating adiponectin is a
primary biomarker for a specific cluster of metabolic syndrome risk factors
rather than all the possible combinations of risk factors currently used to
identify the metabolic syndrome"
