Recent Longevity News for the seven days ending
2/6/13. You should consult your doctor if you are taking any medications.
Low
vitamin D levels may increase risk of Type 1 diabetes - Science Daily,
2/4/13 - "researchers conducted a prospective
case-control study of U.S. military personnel on active duty, using blood
samples from the Department of Defense Serum Repository, which contains more
than 40 million samples collected from 8 million military personnel since the
mid-1980s ... The researchers found that white, non-Hispanic, healthy young
adults with higher serum levels (>75 nmol/L) of
vitamin D had about half the risk of developing type 1
diabetes than those with the lowest levels of
vitamin D (<75 nmol/L) ... The risk of type 1 diabetes appears to be increased
even at vitamin D levels that are commonly regarded as normal, suggesting that a
substantial proportion of the population could benefit from increased vitamin D
intake ... Whereas it is premature to recommend universal use of vitamin D
supplements for prevention of type 1 diabetes, the possibility that many cases
could be prevented by supplementation with 1,000-4,000 IU/day, which is largely
considered safe, is enticing" - See

Beef up:
Middle-aged men may need more to maintain muscle mass - Science Daily,
2/4/13 - "Canada's Food Guide now suggests that
consuming about 3oz (0.80 g/kg/d) of meat per
serving is adequate to provide protein at the recommended level ... However, our
work shows that the quantity of beef needed to maximize the renewal of new
muscle proteins was at least 6oz in middle-aged men. Our findings have clear
ramifications for the current recommendations regarding protein to prevent
muscle loss in aging"
Calcium Supplements
Linked to Mortality Risk in Men, But Not Women - Medscape, 2/4/13 -
"Compared with individuals who took no
calcium, men who consumed 1000 mg or more of
supplemental calcium per day had a significant 20% increased risk of CVD death,
a risk that was driven by a significant 19% increased risk of heart-disease
death ... taken from an analysis of the National Institutes of Health--AARP Diet
and Health Study, a study that included 388 229 men and women 50 to 71 years of
age from six US states ... mean follow-up of 12 years"
Baby Boomers'
Overall Health Worse Than Their Parents - Medscape, 2/4/13 -
"Despite their longer life expectancy over previous
generations, US baby boomers have higher rates of chronic disease, more
disability, and lower self-rated health than members of the previous generation
at the same age ... As to comparative disability, more than twice as many baby
boomers used walking assist devices (6.9% vs 3.3%), more were limited in their
work by disability (13.8% vs 10.1%), and 13.5% vs 8.8% were coping with some
type of functional limitation ... In addition, more baby boomers are obese
compared with the previous generation (38.7% vs 29.4%), and they reported
exercising significantly less often (35.0% vs 49.9% exercised >12 times per
month) ... Moderate drinking was more common among the boomers compared with the
previous generation (67.3% vs 37.2%) ... Hypertension, too, was more common
(43.0% vs 36.4%) ... the present study demonstrates a clear need for policies
that expand efforts at prevention and healthy lifestyle promotion in the baby
boomer generation"
Better Midlife
Fitness Linked to Lower Dementia Risk - Medscape, 2/4/13 -
"Dementia is the second
most feared disease after cancer ... study included 19,458 individuals
participating in the Cooper Clinic Longitudinal Study at the Cooper Institute
... followed for an average of 25 years ... participants with the highest
fitness level (quintile 5) at midlife had a 36% reduction in risk of developing
dementia from any cause during follow-up than those in the lowest fitness
category (quintile 1) ... animal studies have suggested that increased
fitness and activity correlates with a
reduction in brain atrophy and loss of cognition, and changes in amyloid have
been seen with regular activity"
Omega-3-Rich Ground Beef Available Soon - Science Daily, 2/4/13 -
"The U.S. currently does not have a recommended daily
intake of omega-3s, though many doctors and
nutritionists recommend between 1,200-1,600 milligrams daily ... A quarter-pound
hamburger made of the enriched ground beef has 200 milligrams of omega-3s"
- See
Mega Twin EPA at Amazon.com
which has 765 milligrams of omega-3 in one capsule. So you'd have to
eat 3.825 hamburgers to get the omega-3 in one capsule. At 330 calories
per hamburger, that's 1262 calories compared to 10 calories for the capsule.
Plus I'm sure with the mark-up for the designer beef it's not going to be cost
effective either.
Excess
sugar linked to cancer - Science Daily, 2/1/13 - "Dr
Garcia Jimenez's laboratory was studying how cells in the intestine respond to
sugars and signal to the pancreas to release insulin, the key hormone that
controls blood sugar levels. Sugars in the intestine trigger cells to release a
hormone called GIP that enhances insulin release by the pancreas ... the ability
of the intestinal cells to secrete GIP is controlled by a protein called
β-catenin, and that the activity of β-catenin is strictly dependent on sugar
levels ... high (but not normal) sugar levels induce nuclear accumulation of
β-catenin and leads to cell proliferation"
Coffee, Tea, and
Fatal Oral/Pharyngeal Cancer - Medscape, 2/1/13 -
"Intake of >4 cups/day of caffeinated coffee was
associated with a 49% lower risk of
oral/pharyngeal cancer death relative to no/occasional coffee intake
(relative risk = 0.51, 95% confidence interval: 0.40, 0.64) (1 cup/day = 237
ml). A dose-related decline in relative risk was observed with each single
cup/day consumed (P trend < 0.001). The association was not modified by sex,
smoking status, or alcohol use. An inverse association for >2 cups/day of
decaffeinated coffee intake was suggested (relative risk = 0.61, 95% confidence
interval: 0.37, 1.01). No association was found for tea drinking. In this large
prospective study, caffeinated coffee intake was inversely associated with
oral/pharyngeal cancer mortality. Research is needed to elucidate biologic
mechanisms whereby coffee might help to protect against these often fatal
cancers"
Active
duty military personnel prone to sleep disorders and short sleep duration -
Science Daily, 1/31/13 - "the majority of participants
(85.1 percent) had a clinically relevant sleep disorder. Obstructive sleep apnea
(OSA) was the most frequent diagnosis (51.2 percent), followed by insomnia (24.7
percent). Participants' mean self-reported home sleep duration was only 5.74
hours per night, and 41.8 percent reported sleeping five hours or less per
night. According to the AASM, individual sleep needs vary; however, most adults
need about seven to eight hours of nightly sleep to feel alert and well-rested
during the day" - Note: I'm a retired navy pilot (after being an
army helo pilot in Vietnam). The culture in the military seems to be that
if you are getting eights hours of sleep then you can't possibly be doing your
job. Maybe they will wake-up and see that it's doing more harm than good.
Men
taking long-acting chronic pain meds five times more likely to have low
testosterone levels - Science Daily, 1/31/13 - "The
study compared the use of short-acting opioids, which immediately release the
pain medication and are taken every four to six hours, and long-acting opioids,
which slowly release the pain medication and are taken every eight to 12 hours
... A healthy young man should have
testosterone levels between 300 and 800 nanograms per deciliter (ng/dL); in
this study, low testosterone, also known as hypogonadism, was defined as less
than 250 ng/dL. Low testosterone levels have been associated with decreases in
muscle mass, bone density (osteoporosis or osteopenia), cognition, mood, libido
(sex drive) and general quality of life ... the odds of having low testosterone
were 4.78 times greater for men taking a long-acting opioid than a short-acting
opioid. Dose was not associated with an increased risk of low testosterone"
Silibinin, found in milk thistle, protects against UV-induced skin cancer -
Science Daily, 1/30/13 - "A pair of University of
Colorado Cancer Center studies published this month show that the
milk thistle extract, silibinin, kills skin
cells mutated by UVA radiation and protects against damage by UVB radiation --
thus protecting against UV-induced skin cancer and
photo-aging ... When you have a cell affected by UV radiation, you either
want to repair it or kill it so that it cannot go on to cause cancer. We show
that silibinin does both" - See

Vegetarians 'cut heart risk
by 32% - BBC News, 1/30/13 - "A study of 44,500
people in England and Scotland showed
vegetarians were 32% less likely to die or need hospital treatment as a
result of heart disease ... vegetarians had lower blood pressure, lower levels
of "bad" cholesterol and were more likely to have a healthy weight"

Carotenoid
intake and risk of colorectal adenomas in a cohort of male health professionals
- Cancer Causes Control. 2013 Feb 1 - "Among 29,363 men
who reported having a lower bowel endoscopy between 1986 and 2006, 3,997 cases
of colorectal adenoma were identified in the
Health Professionals Follow-up Study. Participants completed food frequency
questionnaires every 4 years ... Total β-carotene and dietary β-carotene,
lycopene and lutein/zeaxanthin intakes and the total
carotenoid score were inversely associated
with colorectal adenoma risk. The odds ratios (95 % confidence intervals)
comparing the highest versus lowest quintile of intake were 0.78 (0.69-0.88) for
total β-carotene, 0.72 (0.64-0.81) for dietary β-carotene, 0.83 (0.74-0.93) for
lycopene, 0.86 (0.76-0.96) for lutein/zeaxanthin, and 0.87 (0.77-0.97) for the

Effects of
Green Tea, Black Tea, and Coffee Consumption on the Risk of Esophageal Cancer: A
Systematic Review and Meta-Analysis of Observational Studies - Nutr Cancer.
2013 Jan;65(1):1-16 - "PubMed, ISI -Web of Science,
China National Knowledge Infrastructure (CNKI), and Chinese VIP database up to
October 2011 were searched and manual search for reference lists of relevant
studies were conducted ... The pooled OR of
EC was 0.77 [95% confidence intervals (95% CI): 0.57, 1.04] for highest vs.
non/lowest green tea consumption; but it was
statistically significant for case-control studies (OR = 0.70; 95% CI: 0.51,
0.96) and for studies conducted in China (OR = 0.64; 95% CI: 0.44, 0.95). No
significant association was observed for the highest vs. non/lowest black tea
consumption against EC risk (OR = 1.35; 95% CI: 0.86, 2.11). A borderline
significantly inverse association of highest vs. non/lowest coffee consumption
against EC risk was found (OR = 0.88; 95% CI: 0.76, 1.01). In conclusion, our
data showed that both green tea and coffee consumption, but not black tea
consumption, have protective effects on EC"

hypothesis that baseline 25(OH)D is associated
with the incidence of T2D in high-risk subjects
for up to 5 y of follow-up, independently of obesity, baseline IR, and β cell
function ... Of the participants, 10.5% had a serum 25(OH)D deficiency (<10
ng/mL), 51.6% had an insufficiency (10.0-19.9 ng/mL), and 38.0% had a
sufficiency (≥20 ng/mL), and the incidence of T2D at 32.3 +/- 15.6 mo (+/-SD)
declined accordingly: 15.9%, 10.2%, and 5.4%, respectively (P < 0.001). After
adjustment for age, sex, blood pressure, lifestyles, family history, season,
parathyroid hormone, and high-sensitivity C-reactive protein, the participants

has been extensively shown, mainly in US populations, that
sugar-sweetened beverages (SSBs) are associated
with increased risk of type 2 diabetes (T2D), but less is known about the
effects of artificially sweetened beverages (ASBs)
... A total of 66,118 women were followed from 1993, and 1369 incident cases of
T2D were diagnosed during the follow-up ... Compared with nonconsumers, women in
the highest quartiles of SSB and ASB consumers were at increased risk of T2D
with HRs (95% CIs) of 1.34 (1.05, 1.71) and 2.21 (1.56, 3.14) for women who
consumed >359 and >603 mL/wk of SSBs and ASBs, respectively. Strong positive

The
association between daily calcium intake and sarcopenia in older, non-obese
Korean adults: the fourth Korea national health and nutrition examination survey
(KNHANES IV) 2009 - Endocr J. 2013 Jan 26 - "The
objective of this study was to assess the relationship between daily
calcium intake and
sarcopenia. We analyzed data for older adults (over 60 years) from the
fourth Korea National Health and Nutrition Examination Survey (KNHANES)
conducted in 2009 ... assessed using a nutrition survey that used a 24-hour
recall method ... We found that daily calcium intake was negatively correlated
with total body fat percentage and positively correlated with appendicular
skeletal mass (p<0.001). Participants with sarcopenia appear to have
significantly lower daily calcium intakes than participants without sarcopenia
(p<0.001). The unadjusted prevalence of sarcopenia according to daily calcium
intake tertiles were 6.3%, 4.3%, and 2.7% in tertiles 1, 2, and 3, respectively.
After adjustment for age, sex, BMI, total energy intake, and lifestyle factors,
compared with those in the lowest tertile of daily calcium intake, participants
in the highest tertile had an odds ratio for sarcopenia of 0.295 (95% confidence
interval, 0.087-0.768; p for trend = 0.014)"
Effect of
Pioglitazone Versus Metformin on Cardiovascular Risk Markers in Type 2 Diabetes
- Adv Ther. 2013 Jan 22 - "The primary objective of this
study was to evaluate the effect on C-reactive protein (CRP) after a 16-week
treatment period with either
pioglitazone or metformin ... Pioglitazone treated patients were found to
have statistically significantly larger decreases in mean CRP levels (-0.4
mg/dL) compared to those treated with metformin (-0.2 mg/dL) (P = 0.04), as well
as greater reductions in levels of mean fasting plasma glucose (-27 vs. -9
mg/dL; P = 0.01), serum insulin (-2 vs. -1.9 mU/L; P = 0.014), homeostatic model
assessment (HOMA) (-1.2 vs. -0.9; P = 0.015), and E-selectin (-12.4 vs. +3.4

treatment groups from baseline to week 16 (-0.4% in the pioglitazone group,
-0.2% in the metformin group; P = 0.36). Pioglitazone treatment was also found
to be associated with a statistically significant increase in total cholesterol

New Use Suggested For St. John's Wort - Psychiatric News, 9/17/04 -
"St. John's wort "may be a useful therapeutic alternative in the acute
treatment of mildly to moderately severe
somatoform disorder." ... The St. John's wort used in this study is from
a specific company, Lichtwer, with a long history of outstanding quality
control and a consistent approach to the processing of St. John's wort.
Individuals going to health food stores and purchasing St. John's wort are
not likely to find the same consistency in the quality of the product"

Effective as Zoloft® against Depression
- New Hope Natural Media Online, 6/13/02 -
"St. John's wort (SJW), a popular herbal remedy, is
at least as effective as the prescription drug
sertraline (Zoloft®) in the treatment of
depression
and causes fewer side effects, according to a new study published in
Canadian Family Physician (2002;48:905–8). This report confirms dozens of
other studies demonstrating SJW is an effective treatment for
mild-to-moderate depression, and contradicts two controversial studies
suggesting the herb is of little or no benefit ... After 12 weeks, the
severity of depression had decreased by an average of 50.2% in the SJW group
and by 41.6% in the sertraline group"

"German doctor's now prescribe St. John's wort
extract 8 times more often than Prozac ... These doctors are knowledgeable

simple answer is that St. John's wort produces equal or better results in
relieving depression, but has far fewer side effect. Over 25 double-blind
randomized trials involving a total of 1,757 outpatients with mild to
moderately severe depression have shown St. John's wort extracts
standardized for hypericin to yield excellent results in the treatment in
depression with virtually no side effects"
