How Tom Cruise has turned into Benjamin Button - MSNBC, 2/27/12 -
"Scuptra is typically injected every six weeks for three
or four treatments. The effect is so gradual that people often don't even spot
it ... while he doesn't think Cruise has had a
facelift, he suspects he's having regular skin-tightening treatments. One
candidate is ReFirme, a light-based treatment that combines radio frequency and

Can Vitamin D Treat Pain?
- Medscape, 2/27/12 - "Dysmenorrhea affects almost one
half of menstruating women. The pelvic pain is believed to be triggered by
excessive uterine production of prostaglandins, synthesized from omega-6 fatty
acids before menses, that control vasoconstriction and uterine contractions ...
vitamin D may act as an anti-inflammatory and may regulate the expression of key
genes involved in the prostaglandin pathway, causing decreased biological
activity of prostaglandins ... The women were randomly assigned to receive a
single oral dose of 300,000 IUs of vitamin D (cholecalciferol) or placebo 5 days
before the time they expected to begin their next menstrual period ... After 2
months, baseline pain scores decreased 41% among women in the vitamin D group;
there was no difference in scores among women taking placebo ... The 300,000 IU
dose of vitamin D used in the study is probably harmless if taken every month or
2, and even perhaps every week, but it could cause hypercalcemia if taken daily"

dysfunction - Wikipedia, the free encyclopedia -
"Endothelial dysfunction is a systemic pathological state of the endothelium
(the inner lining of blood vessels) and can be broadly defined as an
imbalance between vasodilating and vasoconstricting substances produced by
(or acting on) the endothelium. Normal functions of endothelial cells
include mediation of coagulation, platelet adhesion, immune function and
control of volume and electrolyte content of the intravascular and
extravascular spaces. Endothelial dysfunction can result from and/or
contribute to several disease processes, as occurs in septic shock,
hypertension, hypercholesterolaemia, diabetes, it can also result from
environmental factors, such as from smoking tobacco products and exposure to

AMD-like lesions delayed in mice fed lower glycemic index diet - Science
Daily, 11/14/11 - "The dietary glycemic index (DGI)
measures the rate at which glucose is delivered to the bloodstream after
consuming carbohydrates. Higher GI foods including white bread and white
potatoes trigger a rapid delivery of glucose that pushes the body to work
overtime to absorb, whereas lower GI foods, like whole grain bread and
fruits and vegetables, initiate a slower release of glucose that is more
easily processed by cells ... Compared to the mice on the lower GI diet,
mice on the higher GI diet demonstrated elevated accumulations of debris
known as advanced glycation end products (AGEs) in the whole retina,
particularly in the cells of the RPE. The RPE plays a crucial role in
maintaining vision and its dysfunction results in the gradual central vision
loss that is the hallmark of AMD. AGE accumulation has also been linked to
tissue damage in other age-related diseases such as Type 2 diabetes and
Eating the Wrong Kind of Carbohydrates Increases Heart Disease Risk -
U.S. News and World Report, 4/12/10 - "women who ate
the most "high-glycemic" carbohydrates—which cause quick spikes in blood
sugar levels—had more than twice the risk of having heart disease as those
who ate the least. (The study didn't find the same association in men.)
What's interesting, though, is that it was the type of carbs, not the
amount, that had the health impact. "High consumption of carbohydrate from
high-glycemic foods, rather than overall quantity of carbohydrate consumed,
appears to influence the risk of developing heart disease in women,""

Glycemic Breakfast May Increase Benefits Of Working Out - Science Daily,
4/15/09 - "Overall, fat oxidation was higher in the
LGI treatment than in the HGI treatment (P < 0.05) during the post-breakfast
and exercise periods. Following lunch, fullness scores were higher in the
LGI trial than in the HGI trial (P < 0.05). The authors concluded that
consuming a LGI breakfast increases fat oxidation during subsequent exercise
and improved satiety during recovery in sedentary females. As such,
individuals trying to shed fat may consider choosing LGI foods eaten prior
to when they exercise"

significant, both statistically and clinically"
Strategies for Improving Post-Prandial Glucose, Lipids, and More -
Medscape, 1/29/08 - "The amount and type of
carbohydrate consumed with a meal is a major determinant of the
post-prandial glucose excursion. The glycemic index of a food is defined
as the incremental increase in the area under the post-prandial glucose
curve after ingestion of 50 g of a specific food compared with that noted
after ingestion of 50 g of oral glucose. A meal such as white bread and
jelly with a glycemic index of 80 will result in a 2-fold higher incremental
increase in glucose compared with an isocaloric meal of whole-grain bread
and peanut butter with a glycemic index of 40. Most studies show that diets
rich in high-glycemic-index, low-fiber foods independently increase the risk
of both CV disease and type 2 diabetes ... Excess intake of processed
carbohydrates sets up a vicious cycle whereby the transient spikes in blood
glucose and insulin early after a meal trigger reactive hypoglycemia and
hunger. The chronic consumption of a diet high in processed
carbohydrates leads to excess visceral fat, which increases both insulin
resistance and inflammation and predisposes to diabetes, hypertension, and
CV disease. In contrast, restriction of refined carbohydrates will
improve the post-prandial levels of both glucose and triglycerides and can
reduce intra-abdominal fat, particularly in individuals with insulin
resistance ... Recent studies show that 1 to 2 tablespoons of vinegar, when
added to a meal containing high-glycemic-index foods such as white bread or
white rice, will both: 1) lower post-prandial glucose by 25% to 35% (Fig.
5), and 2) increase post-meal satiety by more than 2-fold. Thus the
addition of vinegar to a standard meal can not only improve the meal-induced
oxidant stress by blunting the post-prandial glucose excursion, but also can
increase and prolong satiety, which should help to reduce food cravings and
lower caloric intake over the subsequent 2 to 4 h" - See

- 4.5 tablets equals about 3 tablespoons by my calculations. I've been
popping 4 of these with meals for years and more and more research keeps
backing me up. If 1 to 2 tablespoons is correct you could get by with
just two tablets.

Dietary Experts Debate Carbohydrates - Intelihealth, 9/2/03 -
"Blood sugar levels may shoot twice as high after a high-GI meal as after a

of insulin, which prompts it to quickly store the sugar in muscle and fat
cells. The high sugar also inhibits another hormone, glucagon, which
ordinarily tells the body to burn its stored fuel ... Blood sugar plunges.
So much is stored so fast that within two or three hours, levels may be
lower than they were before the meal. Suddenly, the body needs more fuel.
But because glucagon is still in short supply, the body does not tap into
its fat supply for energy. The inevitable result? Hunger ... After one year,
the low-GI volunteers had dropped seven pounds of pure fat. The others had
put on four"

Aggressive Prostate Cancer Risk - Nutr Cancer. 2011 Jul 20 -
"Here we further investigate such potential
relationships with a case-control study of 982 men (470 more aggressive prostate
cancer cases and 512 control subjects). Comparing the highest to lowest
quartiles of intake, we found that increasing intakes of leafy vegetables were
inversely associated with risk of aggressive prostate cancer [adjusted odds
ratio (OR) = 0.66, 95% CI: 0.46, 0.96; P trend = 0.02], as was higher
consumption of high carotenoid vegetables (OR = 0.71, 95% CI: 0.48, 1.04; P
trend = 0.04). Conversely, increased consumption of high glycemic index foods
were positively associated with risk of aggressive disease (OR = 1.64, 95% CI:
1.05, 2.57; P trend = 0.02). These results were driven by a number of specific
foods within the food groups. Our findings support the hypothesis that diets
high in vegetables and low in high glycemic index foods decrease risk of
aggressive prostate cancer"
Nutrition Is Associated with the 5-Year Incidence of Chronic Kidney Disease
- J Nutr. 2011 Jan 12 - "participants in the 4th

After multivariable adjustment, participants in the 4th quartile of dietary
cereal fiber intake compared with those in the first quartile (reference) had a
50% reduced risk of incident moderate CKD (P-trend = 0.03). Higher baseline
consumption of energy-dense, nutrient-poor sources of carbohydrate (e.g.
cookies) yielded a 3-fold higher risk of incident CKD (P-trend = 0.01). In
summary, we observed a novel link between high cereal fiber intake and reduced
incidence of moderate CKD and this was supported by the cross-sectional
association with dietary GI. Conversely, our data suggest that higher intake of
energy-dense, nutrient-poor sources of carbohydrate, potentially through acute
hyperglycemia, could impair renal function"

hyperglycaemia - Diabetes Res Clin Pract. 2010 Nov 19 -
"Diet GI on control (58, 95% CI: 56,60) was
significantly higher than on low-GI (49, 95% CI: 47,51; p=0.001). Glycaemic
control improved on both diets, but more postprandial glucose values were within
target on low-GI (58.4% of n=1891) than control (48.7% of n=1834; p<0.001). SMBG
post-breakfast was directly related to pre-pregnancy BMI in the control, but not
the low-GI group (BMI*diet interaction; p=0.021). Participants accepted the
study foods and were willing to consume them post-intervention ... A low-GI diet
was feasible and acceptable in this sample and facilitated control of
postprandial glucose. A larger study is needed to determine the effect of a
low-GI diet on maternal and infant outcomes"
Glycemic Load Is a Predictor of Age-Related Hearing Loss in Older Adults - J
Nutr. 2010 Oct 6 - "Participants in the highest quartile
of mean dietary GL intake compared with those in the lowest quartile had a 76%
greater risk of developing incident hearing loss (P-trend = 0.04). Higher
carbohydrate and sugar intakes were associated with incident hearing loss
(P-trend = 0.03 and P-trend = 0.05, respectively). In summary, a high-GL diet
was a predictor of incident hearing loss, as was higher intake of total
carbohydrate. Hence, high postprandial glycemia might be a potential underlying
biological mechanism in the development of age-related hearing loss"
quantity and quality and risk of type 2 diabetes in the European Prospective
Investigation into Cancer and Nutrition-Netherlands (EPIC-NL) study - Am J
Clin Nutr. 2010 Aug 4 - "glycemic load (GL), glycemic
index (GI) ... During a mean follow-up of 10 y, 915 incident diabetes cases were
documented. Dietary GL was associated with an increased diabetes risk after
adjustment for age, sex, established diabetes risk factors, and dietary factors
[hazard ratio (HR) per SD increase: 1.32; 95% CI: 1.14, 1.54; P lt 0.001]. GI
tended to increase diabetes risk (HR: 1.08; 95% CI: 1.00, 1.17; P equals 0.05).
Dietary fiber was inversely associated with diabetes risk (HR: 0.92; 95% CI:
0.85, 0.99; P lt 0.05), whereas carbohydrate intake was associated with
increased diabetes risk (HR: 1.15; 95% CI: 1.01, 1.32; P lt 0.05). Of the
carbohydrate subtypes, only starch was related to increased diabetes risk [HR:
1.25 (1.07, 1.46), P lt 0.05]. All associations became slightly stronger after
exclusion of energy misreporters. CONCLUSIONS: Diets high in GL, GI, and starch
and low in fiber were associated with an increased diabetes risk. Both
carbohydrate quantity and quality seem to be important factors in diabetes
prevention. Energy misreporting contributed to a slight attenuation of
Postprandial Glycemia by the Novel Viscous Polysaccharide PGX, in a
Dose-Dependent Manner, Independent of Food Form - J Am Coll Nutr. 2010
Apr;29(2):92-8 - "The objective of the study therefore
was to determine palatability and effectiveness of escalating doses of PGX, a
novel viscous polysaccharide (NVP), in reducing postprandial glycemia when added
to a liquid and a solid meal ... Addition of NVP to the meal reduced blood
glucose incremental areas under the curve irrespective of dose, reaching
significance at the 7.5 g dose when added to glucose (p < 0.01), and at the 5
and 7.5 g doses when added to WB + Marg (p < 0.001). The GI values of glucose
with 0, 2.5, 5, or 7.5 g of NVP were (mean +/- standard error of the mean [SEM])
100.0 +/- 0.0, 83.7 +/- 9.0, 77.7 +/- 8.2, and 72.5 +/- 5.9, respectively; the
GI of the WB alone, or of WB + Marg, with 0, 2.5, 5, or 7.5 g of NVP was 71.0
+/- 0.0, 66.8 +/- 3.0, 47.5 +/- 5.9, 37.3 +/- 5.9, and 33.9 +/- 3.6,
respectively. CONCLUSION: Addition of NVP to different food matrices is highly
effective in lowering the glycemic index of a food in a dose-responsive manner"

load, glycemic index and breast cancer risk in a prospective cohort of
Swedish women - Int J Cancer. 2009 Feb 3 - "In
analyses stratified by estrogen receptor (ER) and progesterone receptor (PR)
status of the breast tumors, we observed statistically significant positive
associations of carbohydrate intake, glycemic index and glycemic load with
risk of ER+/PR- breast cancer; the multivariate relative risks comparing
extreme quintiles were 1.34 [95% confidence interval (CI) = 0.93-1.94; p for
trend = 0.04] for carbohydrate intake, 1.44 (95% CI = 1.06-1.97; p for trend
= 0.01) for glycemic index and 1.81 (95% CI = 1.29-2.53; p for trend =
0.0008) for glycemic load. No associations were observed for ER+/PR+ or
ER-/PR- breast tumors. These findings suggest that a high carbohydrate
intake and diets with high glycemic index and glycemic load may increase the
risk of developing ER+/PR- breast cancer"
Index, Retinal Vascular Caliber, and Stroke Mortality - Stroke. 2008 Oct
23 - "high glycemic index (GI) and low cereal fiber
(CF) ... Persons consuming food in the highest GI tertile and lowest CF
tertile had a 5-fold increased risk of stroke death ... High-GI and low-CF
diets predict greater stroke mortality and wider retinal venular caliber.
The association between a high-GI diet and stroke death was partly explained
by GI effects on retinal venular caliber, suggesting that a high-GI diet may
produce deleterious anatomic changes in the microvasculature"
glycemic index and the risk of age-related macular degeneration - Am J
Clin Nutr. 2008 Oct;88(4):1104-10 - "a higher mean
dietary glycemic index was associated with an increased 10-y risk of early
AMD in a comparison of quartiles 1 and 4 [relative risk (RR): 1.77; 95% CI:
1.13, 2.78; P for trend = 0.03]. Conversely, a greater consumption of cereal
fiber (RR: 0.68; 95% CI: 0.44, 1.04; P for trend = 0.05) and breads and
cereals (predominantly lower glycemic index foods such as oatmeal) (RR:
0.67; 95% CI: 0.44, 1.02; P for trend = 0.03) was associated with a reduced
risk of incident early AMD ... A high-glycemic-index diet is a risk factor
for early AMD-the recognized precursor of sight-threatening late AMD.
Low-glycemic-index foods such as oatmeal may protect against early AMD"

The glycemic index and cardiovascular disease risk - Curr Atheroscler
Rep. 2007 Dec;9(6):479-85 - "dietary GI and/or
glycemic load independently predict cardiovascular disease, with relative
risk ratios of 1.2 to 1.7 comparing highest and lowest quintiles. In
randomized controlled trials in overweight subjects, diets based on low-GI
carbohydrates have produced better cardiovascular-related outcomes than
conventional low-fat diets. Taken together, the findings suggest that health
professionals may be able to improve cardiovascular outcomes by recommending
the judicious use of low- GI/glycemic load foods"
Dietary glycemic load, added sugars, and carbohydrates as risk factors for
pancreatic cancer: the Multiethnic Cohort Study - Am J Clin Nutr. 2007
Nov;86(5):1495-501 - "Glycemic load and added sugars
were not significantly associated with pancreatic cancer risk. The risk
increased with higher intakes of total sugars, fructose, and sucrose, and
the association with fructose was significant when the highest and lowest
quartiles were compared (relative risk: 1.35; 95% CI: 1.02, 1.80; P for
trend = 0.046). A significant association was found with fruit and juices
intake (1.37; 1.02, 1.84; P for trend = 0.04) but not with soda intake.
Statistical evidence of a significant interaction with body mass index was
present only for sucrose intake (P = 0.04). A comparison of the highest and
lowest quartiles of sucrose intake in overweight or obese participants gave
a relative risk of 1.46 (0.95-2.25; P for trend = 0.04), but the comparison
was not significant in normal-weight participants"

Oct 19 - "Compared with the lowest tertile, the ORs
in subsequent tertiles were 1.68 and 1.73 for GI, and 1.76 and 2.17 for GL.
The OR for highest tertile of GI compared with lowest one was 1.70 for
papillary and 1.57 for follicular thyroid cancer. The ORs for GL were 2.17
for papillary and 3.33 for follicular thyroid cancer ... Our study shows
that high dietary levels of GI and GL are associated with thyroid cancer
Dietary glycemic index, glycemic load, and the risk of breast cancer in an
Italian prospective cohort study - Am J Clin Nutr. 2007
Oct;86(4):1160-1166 - "The relative risk (RR) of
breast cancer in the highest (versus lowest) quintiles of GI and GL was 1.57

for trend = 0.001), respectively. Total carbohydrate intake was not
associated with greater breast cancer risk, but high carbohydrate from
high-GI foods was. When women were categorized by baseline menopausal status
and body mass index (BMI; in kg/m(2)), the increased risk of dietary GL was
confined to those who were premenopausal (RR = 3.89; 95% CI: 1.81, 8.34) and
who had normal BMI (ie, <25)"

Low-carbohydrate-diet score and the risk of coronary heart disease in women
- N Engl J Med. 2006 Nov 9;355(19):1991-2002 -
"During 20 years of follow-up, we documented 1994 new cases of coronary
heart disease. After multivariate adjustment, the relative risk of coronary
heart disease comparing highest and lowest deciles of the
low-carbohydrate-diet score was 0.94 (95% confidence interval [CI], 0.76 to
1.18; P for trend=0.19). The relative risk comparing highest and lowest
deciles of a low-carbohydrate-diet score on the basis of the percentage of
energy from carbohydrate, animal protein, and animal fat was 0.94 (95% CI,
0.74 to 1.19; P for trend=0.52), whereas the relative risk on the basis of
the percentage of energy from intake of carbohydrates, vegetable protein,
and vegetable fat was 0.70 (95% CI, 0.56 to 0.88; P for trend=0.002). A
