Study links low-GI kids' breakfast to less calories - Nutra USA, 9/4/07 -
"The children ate on average 61 kcal less over the days they were given the
low-GI breakfast, compared with the days when they ate a high-GI breakfast"
Avocados
May Help Prevent Oral Cancer, Study Shows - Science Daily, 9/4/07 -
"Nutrients taken from avocados are able to thwart oral
cancer cells, killing some and preventing pre-cancerous cells from developing
into actual cancers"
More vitamin D could mean fewer cancers: study - Reuters, 9/4/07 -
"They argue that, based on their data, if Americans were
able to maintain a vitamin D level of at least 55 ng/mL, 60,000 cases of colon
cancer and 85,000 cases of breast cancer could be prevented every year.
Worldwide, those figures could be 250,000 and 350,000, respectively ... Garland
and his colleagues recommend that, in addition to modest sun exposure, adults
get 2,000 IU of vitamin D per day -- which is the "tolerable upper intake level"
set by U.S. health officials"
Fat
Transforms Vitamin C From 'Good Cop' Into 'Bad Cop' - Science Daily, 9/4/07
- "Nitrites, which are present in human saliva, and in
certain preserved foodstuffs, may be converted to cancer causing compounds
called nitrosamines. Nitrosamines are formed in acidic conditions, such as those
afforded by stomach acid, but vitamin C inhibits their formation, by converting
nitrite to nitric oxide ... Without fat, vitamin C curbed the levels of two
nitrosamines by a factor of between five and 1000. And it completely eliminated
the production of the other two ... But when 10% fat was added, vitamin C
actually boosted the production of nitrosamines between 8 and 140-fold"
Red Wine
Compound Shown To Prevent Prostate Cancer - Science Daily, 8/31/07 -
"n the study resveratrol-fed
mice showed an 87 percent reduction in their risk of developing
prostate tumors that contained the worst kind
of cancer-staging diagnosis ... Other mice in the study, those fed resveratrol
but still developed a less-serious form of prostate cancer, were 48 percent more
likely to have their tumor growth halted or slowed when compared to mice who did
not consume the compound ... A cancer prevention researcher lives for these days
when they can make that kind of finding" - See

Heavy
Drinking Raises Blood Pressure In Older Men Regardless Of 'Good' Cholesterol
- WebMD, 8/31/07 - "When looking at men of all ages,
those with the lowest level of good cholesterol had
the highest blood pressure in all three
groups: nondrinkers, moderate drinkers and heavy drinkers. However, high levels
of good cholesterol HDL did not do as much for the heavy drinkers"
Human
Papilloma Virus Vaccines May Decrease Chances Of Oral Cancer - Science
Daily, 8/30/07 - "oral and oropharyngeal squamous cell
carcinoma (OOSCC) have been linked to high-risk HPV strains, the same strains
that cause cervical cancer ... It's possible that oral and oropharyngeal cancers
could be reduced if vaccination were more widespread; however, additional
research is needed"
Antioxidant To Retard Wrinkles Discovered - Science Daily, 8/30/07 -
"Antioxidants operate against free radicals which cause
a breakdown of many tissues in the body, including the skin. When found in small
quantities in the body, free radicals are not harmful and are even involved in
various physical processes. When there is an excess of free radicals, however,
as occurs during normal aging or as a result of excessive exposure to
ultra-violet radiation from the sun, the result, among other things, is a
breakdown of the collagen and elastin fibers in the skin. When this happens,
there is a loss of skin elasticity and the formation of wrinkles ... A problem
with many of the commercial antioxidants found today in the market that are said
to retard the aging process is that they oxidize quickly and therefore their
efficiency declines with time"
High Hostility Linked with Poor Ability to Cope With Stress, Low HDL Levels
- Medscape, 8/30/07 - "individuals who were very hostile
were more likely to perceive problems as stressful and to cope with
stress by using interpersonal hostility,
self-blame, and social isolation; they also tended to have lower levels of
HDL"
Flaxseed
Shows Potential To Reduce Hot Flashes - Science Daily, 8/29/07 -

Household Mold Linked To Depression - Science Daily, 8/29/07 -
"Shenassa said that given the results of the current
study, he wouldn’t be surprised if there is a cause-and-effect association.
Molds are toxins, and some research has indicated
that these toxins can affect the nervous system or the immune system or impede
the function of the frontal cortex, the part of the brain that plays a part in
impulse control, memory, problem solving, sexual behavior, socialization and
spontaneity"
Ovary removal may cause dementia risk - USA Today, 8/29/07 -
"women who'd had one or both ovaries removed showed
about a 50% increase in risk of the later mental problems"
Who Should Get the HPV Vaccine? - Time Magazine, 8/28/07 -
"From a public health standpoint, that logic seems to
makes sense. Since 80% of women who have sex will acquire the virus by age 50
(in most cases it causes no health problems and clears the body within two
years), it accomplishes little to give the vaccine to older, sexually active
women, who may already have HPV or have already spread it within the community.
But humanpapillomavirus isn't a single virus; rather, it's a family of viruses
that includes at least 100 strains, more than 30 of which are transmitted
sexually. About 10 of those can cause cervical cancer; others may cause genital
warts. So even if a woman has been exposed to one strain of HPV, there may well
be others that she is still vulnerable to. HPV also poses a threat to men
because genital warts can develop into oral cancer, and a new study in the
medical journal Cancer
suggests that young men be vaccinated against HPV"

Dietary fiber intake and risk of postmenopausal breast cancer defined by
estrogen and progesterone receptor status-A prospective cohort study among
Swedish women - Int J Cancer. 2007 Aug 31 -
"estrogen receptor (ER)/progesterone receptor (PR)-defined
breast cancer risk ... When comparing the highest
to the lowest quintile, we observed non-significant inverse associations between
total fiber intake and the risk of all tumor subtypes; the multivariate-adjusted
RRs were 0.85 (95% CI: 0.69-1.05) for overall, 0.85 (0.64-1.13) for ER+PR+, 0.83
(0.52-1.31) for ER+PR- and 0.94 (0.49-1.80) for ER-PR-. For specific
fiber, we observed statistically significant risk
reductions for overall (34%) and for ER+PR+ (38%) for the highest versus lowest
quintile of fruit fiber, and non-significant inverse associations for other
subtypes of cancer and types of fiber. Among ever-users of postmenopausal
hormone (PMH), total fiber intake and especially cereal fiber were statistically
significantly associated with approximately 50% reduced risk for overall and
ER+PR+ tumors when comparing the highest to the lowest quartile, but no
association was observed among PMH never users"

Use of Statins and Blood Pressure - Am J Hypertens. 2007 Sep;20(9):937-941 -
"Compared with people not using statin medication,
significantly more statin users had their
blood pressure under control (52.2% v 38.0%).
After adjustment for demographic factors, statin users were two times (95%
confidence interval [CI], 1.46 to 2.72) more likely to have their blood pressure
under control (<140/90 mm Hg) than nonusers. After further adjustment for body
mass index, diabetes, smoking, exercise, low-salt diet, and antihypertensive
medications, the likelihood of having blood pressure under control remained more
likely among statin users (odds ratio, 1.46; 95% CI, 1.05 to 2.05)"
The red clover (Trifolium pratense) isoflavone biochanin A inhibits aromatase
activity and expression - Br J Nutr. 2007 Aug 29;:1-8 -
"Biochanin A is an isoflavone isolated from
red clover (Trifolium pratense) ...
Isoflavones resemble the structure of oestrogen, and display agonistic and
antagonistic interactions with the oestrogen receptor. Overexposure of oestrogen
is a major contributing factor in the development of breast cancer ... In the
present study the effect of biochanin A on the gene regulation and enzyme
activity of aromatase was investigated. By assaying MCF-7 cells stably
transfected with CYP19, biochanin A inhibited aromatase activity and hampered
cell growth attributing to the enzyme activity" - See

Liver dysfunction in paediatric obesity: a randomized, controlled trial of
metformin - Acta Paediatr. 2007 Sep;96(9):1326-32 -
"In obese adolescents fed ad libitum, metformin
(a) prevented the rise in ALT concentrations that were observed in
placebo-treated subjects at the 3 to 5 month time-points (p < 0.05); (b) reduced
(p < 0.01) the percentage of all ALT values exceeding 40 U/L; and (c) caused a
modest (10%) but statistically significant (p < 0.05) reduction in serum ALT in
Caucasian subjects. Metformin had no effect on ALT levels or the ALT to AST
ratio in the five African American adolescents enrolled in the study ...
metformin might reduce the rates or severity of liver dysfunction in selected
high-risk adolescents"

increased from 10.0 +/- 4.6 to 13.9 +/- 4.7 ml/mmHg x 100 after 2 years (P =
0.003). The small artery elasticity (SAEI) index increased significantly from
3.2 +/- 1.2 to 5.1 +/- 1.9 (P < 0.0001). In patients who discontinued
rosiglitazone: LAEI did not change after 6 months, but decreased from 12.1 +/-
5.4 to 8.9 +/- 3.9 ml/mmHg x 10 (P < 0.0001) at the end of 2 years. SAEI
increased during the first 6 months of treatment, from 3.9 +/- 1.8 to 5.1 +/-
1.5 ml/mmHg x 100 (P < 0.0001) and decreased after discontinuation of
rosiglitazone (P = 0.042)"
Nutritional intervention to reduce the n-6/n-3 fatty acid ratio increases
adiponectin concentration and fatty acid oxidation in healthy subjects - Eur
J Clin Nutr. 2007 Aug 15 - "Dietary intervention was
associated with significant reductions in TNF-alpha (baseline: 2.2 (s.d. 0.3),
post-intervention: 1.5 (s.d. 0.3) pg/ml, P=0.01) and low-density
lipoprotein-cholesterol (baseline: 2.5 (s.d. 0.2), post-intervention: 2.3 (s.d.
0.1) mmol/l, P=0.03) and increased adiponectin
(baseline: 6.5 (s.d. 0.7), post-intervention: 7.6 (s.d. 0.6) mug/ml, P=0.02).
Fasting lipid oxidation was increased (baseline: 0.7 (s.d. 0.1),
post-intervention: 0.9 (s.d. 0.1) mg/kg.min, P=0.01), whereas glucose oxidation
decreased in both fasting (baseline: 1.6 (s.d. 0.1), post-intervention: 1.3
(s.d. 0.1) mg/kg.min, P=0.02) and hyperinsulinaemic conditions (baseline: 3.6
(s.d. 0.1), post-intervention: 3.3 (s.d. 0.1) mg/kg.min, P=0.04). Insulin
sensitivity was not affected by the intervention. Conclusion: A decreased
n-6/n-3 PUFA ratio can be achieved with simple dietary counselling, resulting in
multiple, potentially favourable effects on the metabolic and inflammatory
profiles"

"Rickets is a disease typically caused by vitamin D
deficiency; the classic symptom is weakened or deformed bones. The disease
was common a century ago during the Industrial Revolution when children went
malnourished and without regular exposure to the sun, which triggers the
body to make vitamin D. But now, thanks to a better understanding of
nutrition, and fortification of certain foods, rickets is preventable and
extremely rare in the U.S."

minimum desirable target 25(OH)D concentration, then current recommendations
of 15mcg per day do not meet the criterion of an RDA"

Vitamin D deficiency: new perspectives on an old disease
- Endocrinology and Diabetes, 2/04 -
"Even though vitamin D deficiency has been thought to
be obsolete in developed countries such as the United States, recent data
suggest that this diagnosis may exist in epidemic proportions. Chronic
vitamin D deficiency may be associated with a susceptibility to
hypertension, multiple sclerosis, and various malignancies, problems beyond
the more commonly recognized skeletal manifestations" - See

Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart
disease, and osteoporosis - Am J Clin Nutr. 2004 Mar;79(3):362-71 -
"Vitamin D deficiency is often misdiagnosed as
fibromyalgia ... Studies in both human and animal models add strength to
the hypothesis that the unrecognized epidemic of vitamin D deficiency
worldwide is a contributing factor of many chronic debilitating diseases ...
The recommended adequate intakes for vitamin D are inadequate, and, in the
absence of exposure to sunlight, a minimum of 1000 IU vitamin D/d is
required to maintain a healthy concentration of 25(OH)D in the blood"

Vitamin D and prostate cancer prevention and treatment
- Trends Endocrinol Metab. 2003 Nov;14(9):423-30 -
"The association between either decreased sun exposure or vitamin D
deficiency and the increased risk of prostate cancer at an earlier age, and
with a more aggressive progression, indicates that adequate vitamin D
nutrition should be a priority for men of all ages"

Prevalence of hypovitaminosis D in elderly women in Italy: clinical
consequences and risk factors - Osteoporos Int. 2003 Jul 11 -
"Vitamin D deficiency is extremely common among elderly Italian women ...
Hypovitaminosis D is associated with worsening of the ability to perform
activities of daily living and higher hip fracture prevalence. This finding
should lead to an urgent population-based strategy to remedy this condition"
- Vitamin D Deficiency
Masquerading as Pseudohypoparathyroidism Type 2
- Journal of The Association of Physicians of India, 6/03 -
"Phenytoin and phenobarbitone are well known to
cause vitamin D deficiency by decreasing intestinal absorption and
increasing metabolism of 25 (OH) D in liver ... vitamin D deficiency can
mimic PHP-II and therefore before considering this rare diagnosis vitamin D
deficiency must be excluded"

Oral vitamin D3 decreases fracture risk in the elderly
- J Fam Pract. 2003 Jun;52(6):431-5 - "Despite a
seemingly large dose averaging 800 IU per day, this regimen is a safe, cheap
(<$2 per year), and effective therapy for primary prevention of fractures"

Vitamin D in preventive medicine: are we ignoring the evidence?
- Br J Nutr 2003 May;89(5):552-572 - "European
children and young adults often have circulating 25(OH)D levels in the
insufficiency range during wintertime. Elderly subjects have mean 25(OH)D
levels in the insufficiency range throughout the year. In institutionalized
subjects 25(OH)D levels are often in the deficiency range. There is now
general agreement that a low vitamin D status is involved in the
pathogenesis of osteoporosis. Moreover, vitamin D insufficiency can lead to
a disturbed muscle function. Epidemiological data also indicate a low
vitamin D status in tuberculosis, rheumatoid arthritis, multiple sclerosis,
inflammatory bowel diseases, hypertension, and specific types of cancer.
Some intervention trials have demonstrated that supplementation with vitamin
D or its metabolites is able: (i) to reduce blood pressure in hypertensive
patients; (ii) to improve blood glucose levels in diabetics; (iii) to
improve symptoms of rheumatoid arthritis and multiple sclerosis. The oral
dose necessary to achieve adequate serum 25(OH)D levels is probably much
higher than the current recommendations of 5-15 &mgr;g/d."

Calcium, vitamin D, milk consumption, and hip fractures: a prospective study
among postmenopausal women - Am. J. of Clin. Nutr., 2/03 -
"Women consuming 12.5 µg vitamin D/d from food plus
supplements had a 37% lower risk of hip
fracture (RR = 0.63; 95% CI: 0.42, 0.94) than did women consuming < 3.5
µg/d. Total
calcium intake was not associated with hip
fracture risk (RR = 0.96; 95% CI: 0.68, 1.34 for 1200 compared with < 600
mg/d).
Milk consumption was also not associated with a
lower risk of hip fracture (P for trend = 0.21)"
