28% lower risk of death from all causes than women who ate the least"
Risks
associated with common acid-suppressing medications documented in series of
studies - Science Daily, 5/10/10 - "between 53
percent and 69 percent of proton pump inhibitor prescriptions are for
inappropriate indications ... Use of proton pump inhibitors appears modestly
associated with the risk of total fractures in postmenopausal women ... Daily
proton pump inhibitor use is associated with an estimated 74 percent increase in
infection with Clostridium difficile"
Folic
acid found to improve vascular function in amenorrheic runners - Science

which correlates with increased blood flow to the heart"
NASA
studies find omega-3 may help reduce bone loss - Science Daily, 5/10/10 -
"In a series of cell-based studies, scientists
documented that adding a specific omega-3 fatty acid
to cells would inhibit the activation of factors that lead to
bone breakdown. This was true in both
typical cell cultures and those designed to mimic weightlessness. The inhibited
factor is known as "nuclear factor kappa B" or NFκB. NFκB is involved in immune
system behavior and the inflammation process. The activation of NFκB in
different tissues can lead to bone and muscle loss" - See Nutra USA

New
vitamin D recommendations for older men and women - Science Daily, 5/10/10 -
"The estimated average
vitamin D requirement of older adults to reach a serum 25OHD level of 75
nmol/l (30ng/ml) is 20 to 25 µg/day (800 to 1000 IU/day) ... Intakes may need to
increase to as much as 50 µg(2000IU) per day in individuals who are obese, have
osteoporosis, limited sun exposure (e.g. housebound or institutionalised), or
have malabsorption ... For high risk individuals it is recommended to measure
serum 25OHD levels and treat if deficient" - See
vitamin D at Amazon.com.
Grapes
reduce risk factors for heart disease and diabetes, animal study shows -
Science Daily, 5/10/10 - "After three months, the rats
that received the grape-enriched diet had lower
blood pressure, better heart function, and reduced indicators of
inflammation in the heart and the blood than rats who received no
grape powder. Rats also had lower
triglycerides and improved glucose tolerance" - See Jarrow Formulas, OPCs + 95 at Amazon.com.
Couple of Coffees May Help Some Heart Patients - Medscape, 5/7/10 -
"A study of 374 patients who had a heart attack or other
acute coronary event found those
with normal blood pressure drinking one or two
coffees a day were 88% less likely than non-coffee drinkers to develop left
ventricular systolic dysfunction (LVSD)"
Early Cannabis Use May Contribute to Psychosis-Related Outcomes in Young Adults
- Medscape, 5/7/10 - "twice as likely to develop a
nonaffective psychosis, 4 times as likely to have high scores on the PDI, and 3
times as likely to develop hallucinations ... This study adds to the body of
emerging literature identifying early cannabis
use as a risk factor for schizophrenia ... The concordance between this study
and previous epidemiologic studies strengthens the argument that adolescent
cannabis use is a risk factor for the development of psychosis ... The general
perception that cannabis is a 'soft' drug may not be true. There is now evidence
that cannabis may affect the adolescent brain[, permanently altering] its
developmental trajectory"

Doctors 'cause blood pressure to rise' - BBC News, 5/7/10 -
"The 'white-coat' effect - where blood pressure rises
during a check by a doctor - is even worse in someone whose level is already
high ... The effect is due to patients becoming stressed by being in a doctor's
surgery or a hospital"
Environmental Cancer Risk 'Grossly Underestimated'? - WebMD, 5/6/10 -
"The Panel urges you most strongly to use the power of
your office to remove the carcinogens and other
toxins from our food, water, and air that needlessly increase health care
costs, cripple our nation's productivity, and devastate American lives ... The
presidential panel says this greatly underestimates the problem because it does
not fully account for synergistic interactions between environmental
contaminants, an increasing number and amount of pollutants, and the fact that
all avoidable causes of cancer are not known ... Remove shoes before entering
the house ... Filter home tap or well water. Prefer filtered water to
commercially bottled water ... Store and carry water in stainless steel, glass,
or BPA- and phthalate-free containers ..."
Dietary
protein may reduce hip fractures in the elderly - Science Daily, 5/5/10 -
"individuals who were in the lowest 25 percent of
dietary protein intake had approximately 50
percent more hip fractures than those who
consumed greater amounts of dietary protein (all within normal intakes). Those
who suffered hip fractures consumed less than the 46 grams of dietary protein
per day recommended for adults"
Aspirin Use Linked to Aging Macula Disorder in Older Individuals - Medscape,
5/4/10 - "People 65 years and older who frequently take
aspirin have an increased risk of developing
aging macula disorder — a loss of central vision similar to age-related
macular degeneration — according to a
population-based ... the odds ratios for grade 1 early aging macula disorder
rose with increasing aspirin intake frequency, and reached 1.26 (95% confidence
interval [CI]. 1.08 - 1.46; P trend < .001) for subjects who reported daily use
... Similarly, the odds ratio for grade 2 early aging macula disorder was 1.40
(95% CI, 1.16 - 1.68; P trend < .001) in daily aspirin users; for neovascular
aging macula disorder, the odds ratio was 2.26 (95% CI, 1.66 - 3.08; P trend <
.001) in daily aspirin users"

Improved cognitive-cerebral function in older adults with chromium
supplementation - Nutr Neurosci. 2010 Jun;13(3):116-22 -
"In a placebo-controlled, double-blind trial, we
randomly assigned 26 older adults to receive either
chromium picolinate (CrPic) or placebo for 12 weeks ... Although learning
rate and retention were not enhanced by CrPic supplementation, we observed
reduced semantic interference on learning, recall, and recognition
memory tasks. In addition, fMRI indicated
comparatively increased activation for the CrPic subjects in right thalamic,
right temporal, right posterior parietal, and bifrontal regions. These findings
suggest that supplementation with CrPic can enhance cognitive inhibitory control
and cerebral function in older adults at risk for neurodegeneration" -

Sex Hormones
and the Risk of Incident Prostate Cancer - Urology. 2010 May 6 -
"Serum testosterone,
estradiol, estrone, and
sex hormone-binding globulin were assayed at baseline ... the mean age was
73 years. Higher serum estrone was strongly related to an increased risk of
prostate cancer: compared with men in the lower quartile, the risk of
prostate cancer
among those in the highest 3 quartiles (>24.9 pg/dL) was nearly 4-fold higher
(adjusted heart rate = 3.93, CI: 1.61-9.57). Other sex hormones were not
associated with the risk of prostate cancer" - The following results for
estrone are for women. I didn't find any results for men but see the

"estrone (E(1)), estradiol (E(2)), and estrone
sulfate (E(1)S) ... Treatment with anastrozole suppressed plasma levels of
E(1), E(2), and E(1)S by a mean of 81.0%, 84.9%, and 93.5%, respectively,
whereas treatment with letrozole caused a corresponding decrease of 84.3%,
87.8% and 98.0%, respectively. The suppression of E(1) and E(1)S was found
to be significantly better during treatment with letrozole compared with
anastrozole"
- Note: Testosterone applications such as AndroGel also increase estrogen
whereas letrozole increases testosterone and decreases estrogen:

Letrozole once a week
normalizes serum testosterone in obesity-related male hypogonadism - Eur
J Endocrinol. 2008 May;158(5):741-7 -
"Isolated hypogonadotropic hypogonadism (IHH) is
frequently observed in severely obese men, probably as a result of increased
estradiol (E(2)) production and E(2)-mediated negative feedback on pituitary
LH secretion. Aromatase inhibitors can reverse this process ... treated with
2.5 mg letrozole once a week for 6 months ... Six weeks of treatment reduced
total E(2) from 123+/-11 to 58+/-7 pmol/l (P<0.001, mean+/-s.e.m.), and
increased serum LH from 4.4+/-0.6 to 11.1+/-1.5 U/l (P<0.001). Total
testosterone rose from 5.9+/-0.5 to 19.6+/-1.4 nmol/l (P<0.001), and free
testosterone from 163+/-13 to 604+/-50 pmol/l (P<0.001). Total testosterone
rose to within the normal range in all subjects, whereas free testosterone
rose to supraphysiological levels in 7 out of 12 men ... Letrozole 2.5 mg
once a week produced a sustained normalization of serum total testosterone
in obese men with IHH. However, free testosterone frequently rose to
supraphysiological levels. Therefore, a starting dose <2.5 mg once a week is
recommended"

Comparative assessment in young and elderly men of the gonadotropin response
to aromatase inhibition - J Clin Endocrinol Metab. 2005
Oct;90(10):5717-22 - "As assessed after 28 d of
treatment, letrozole lowered E2 by 46% in the young men (P = 0.002) and 62%
in the elderly men (P < 0.001). In both age groups, letrozole, but not
placebo, significantly increased LH levels (339 and 323% in the young and
the elderly, respectively) and T (146 and 99%, respectively) (P value of
young vs. elderly was not significant). Under letrozole, peak LH response to
GnRH was 152 and 52% increase from baseline in young and older men,
respectively"

- "Six weeks of treatment decreased serum estradiol
from 120 +/- 20 to 70 +/- 9 pmol/l (p = 0.006). None of the subjects
developed an estradiol level of less than 40 pmol/l. LH increased from 4.5
+/- 0.8 to 14.8 +/- 2.3 U/l (p < 0.001). Total testosterone rose from 7.5
+/- 1.0 to 23.8 +/- 3.0 nmol/l (p < 0.001) without a concomitant change in
sex hormone-binding globulin level. Those treated with Letrozole 17.5 mg per
week had an excessive LH response"

25-Hydroxyvitamin D and Depressive Symptoms in Older Women and Men - J Clin
Endocrinol Metab. 2010 May 5 - "Center for
Epidemiological Studies-Depression
Scale (CES-D). Depressed mood was defined as CES-D of 16 or higher ... Women
with 25(OH)D
less than 50 nmol/liter compared with those with higher levels experienced
increases in CES-D scores of 2.1 (P = 0.02) and 2.2 (P = 0.04) points higher at,
respectively, 3- and 6-yr follow-up. Women with low vitamin D (Vit-D) had also
significantly higher risk of developing depressive mood over the follow-up
(hazard ratio = 2.0; 95% confidence interval = 1.2-3.2; P = 0.005). In parallel
models, men with 25(OH)D less than 50 nmol/liter compared with those with higher
levels experienced increases in CES-D scores of 1.9 (P = 0.01) and 1.1 (P =
0.20) points higher at 3- and 6-yr follow-up. Men with low Vit- D tended to have
higher risk of developing depressed mood (hazard ratio = 1.6; 95% confidence
interval = 0.9-2.8; P = 0.1). Conclusion: Our findings suggest that
hypovitaminosis D is a risk factor for the development of depressive symptoms in
older persons. The strength of the prospective association is higher in women
than in men" - See

EPA but not
DHA appears to be responsible for the efficacy of omega-3 long chain
polyunsaturated fatty acid supplementation in depression: evidence from a
meta-analysis of randomized controlled trials - J Am Coll Nutr. 2009
Oct;28(5):525-42 - "Meta-regression studies showed a
significant effect of higher levels of baseline
depression and lower supplement
DHA/EPA ratio on
therapeutic efficacy. Subgroup analyses showed significant effects for: (1)
diagnostic category (bipolar disorder and major depression showing significant
improvement with omega3 LC-PUFA supplementation versus mild-to-moderate
depression, chronic fatigue and non-clinical populations not showing significant
improvement); (2) therapeutic as opposed to preventive intervention; (3)
adjunctive treatment as opposed to monotherapy; and (4) supplement type.
Symptoms of depression were not significantly reduced in 3 studies using pure
DHA (standardized mean difference 0.001, 95% CI -0.330 to 0.332, z = 0.004, p =
0.997) or in 4 studies using supplements containing greater than 50% DHA
(standardized mean difference = 0.141, 95% CI = -0.195 to 0.477, z = 0.821, p =
0.417). In contrast, symptoms of depression were significantly reduced in 13
studies using supplements containing greater than 50% EPA (standardized mean
difference = -0.446, 95% CI = -0.753 to -0.138, z = -2.843, p = 0.005) and in 8
studies using pure ethyl-EPA (standardized mean difference = -0.396, 95% CI =
-0.650 to -0.141, z = -3.051, p = 0.002). However, further meta-regression
studies showed significant inverse associations between efficacy and study
methodological quality, study sample size, and duration, thus limiting the
confidence of these findings. CONCLUSIONS: The current meta-analysis provides
evidence that EPA may be more efficacious than DHA in treating depression.
However, owing to the identified limitations of the included studies, larger,
well-designed, randomized controlled trials of sufficient duration are needed to
confirm these findings" - See

Dietary supplementation of
resveratrol attenuates chronic colonic inflammation in mice - Eur J
Pharmacol. 2010 May 10;633(1-3):78-84 - "Our results
demonstrated that resveratrol group significantly attenuated the clinical signs
such as loss of body weight, diarrhea and rectal bleeding improving results from
disease activity index and inflammatory score. Moreover, the totality of
resveratrol-fed animals survived and finished
the treatment while animals fed with standard diet showed a mortality of 40%.
Three weeks after DSS removal, the polyphenol caused substantial reductions of
the rise of pro-inflammatory cytokines, TNF-alpha and IL-1beta and an increase
of the anti-inflammatory cytokine IL-10. Also resveratrol reduced prostaglandin
E synthase-1 (PGES-1), cyclooxygenase-2 (COX-2) and inducible nitric oxide
synthase (iNOS) proteins expression, via downregulation of p38, a
mitogen-activated protein kinases (MAPK) signal pathway. We conclude that
resveratrol diet represents a novel approach to the treatment of
chronic intestinal inflammation" - See

reduction by constituents of whole grain is a likely mechanism for the
protective effect"

Why whole grains are protective: biological mechanisms - Proc Nutr Soc
2003 Feb;62(1):129-34 -
"First, whole grains are concentrated sources of
dietary fibre, resistant starch and oligosaccharides, carbohydrates that
escape digestion in the small intestine and are fermented in the gut,
producing short-chain fatty acids (SCFA). SCFA lower colonic pH, serve as an
energy source for the colonocytes and may alter blood lipids. These
improvements in the gut environment may provide immune protection beyond the
gut. Second, whole grains are rich in antioxidants, including trace minerals
and phenolic compounds, and these compounds have been linked to disease
prevention. Additionally, whole grains mediate insulin and glucose
responses. Although lower glycaemic load and glycaemic index have been
linked to diabetes and obesity, risk of cancers such as colon and breast
cancer have also been linked to high intake of readily-available
carbohydrate. Finally, whole grains contain many other compounds that may
protect against chronic disease. These compunds include phytate,
phyto-oestrogens such as lignan, plant stanols and sterols, and vitamins and
minerals."
-
Whole grains protect against atherosclerotic cardiovascular disease -
Proc Nutr Soc 2003 Feb;62(1):135-42 -
"Generous intake of whole grains also provides
protection from development of diabetes and obesity. Diets rich in
wholegrain foods tend to decrease serum LDL-cholesterol and triacylglycerol
levels as well as blood pressure while increasing serum HDL-cholesterol
levels. Whole-grain intake may also favourably alter antioxidant status,
serum homocysteine levels, vascular reactivity and the inflammatory state.
Whole-grain components that appear to make major contributions to these
protective effects are: dietary fibre; vitamins; minerals; antioxidants;
phytosterols; other phytochemicals. Three servings of whole grains daily are
recommended to provide these health benefits"
