"According to Spindler's research, the fewer calories an animal consumes -
provided malnutrition is avoided - the slower an animal ages and the lower the death rate from cancer, heart disease and diabetes" - Some theorize that calorie restriction slows aging because it keeps insulin level low (there are other ways that may keep insulin low such as
PGX,
chromium,
Glucophage (metformin),
Actos (pioglitazone),
Avandia (rosiglitazone), etc). See:

Reduction 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

Adiposity
and Insulin Resistance Correlate with Telomere Length in Middle-aged Arabs: The
Influence of Circulating Adiponectin - Eur J Endocrinol. 2010 Aug -
"Studies in obesity have implicated adipocytokines in
the development of insulin resistance, which in
turn may lead to accelerated aging ... HOMA-IR was the most significant
predictor for TL in males, explaining 35% of
the variance (p = 0.01). In females, adiponectin,
accounted for 28% of the variance in TL (p = 0.01). Conclusion: Obesity and
insulin resistance are associated with chromosomal TL among adult Arabs.
Evidence of causal relations needs further investigation. The positive
association of adiponectin to TL has clinical implications as to the possible
protective effects of this hormone from accelerated aging" - Note:
HOMA-IR = (glucose x insulin)/405 for glucose in mass units (US units) mg/dL.

Diabetes linked to cognitive impairment in older adults, study suggests
- Science Daily, 11/8/11 - "in older patients with
diabetes, two adhesion molecules -- sVCAM and sICAM -- cause inflammation in
the brain, triggering a series of events that affect blood vessels and,
eventually, cause brain tissue to atrophy. Importantly, they found that the
gray matter in the brain's frontal and temporal regions -- responsible for
such critical functions as decision-making, language, verbal memory and
complex tasks -- is the area most affected by these events ... at the age of
65, the average person's brain shrinks about one percent a year, but in a
diabetic patient, brain volume can be lowered by as much as 15 percent ...
Diabetes develops when glucose builds up in the blood instead of entering
the body's cells to be used as energy. Known as hyperglycemia, this
condition often goes hand-in-hand with inflammation ... Once chronic
inflammation sets in, blood vessels constrict, blood flow is reduced, and
brain tissue is damaged"

Low-carbohydrate, high-protein diets may reduce both tumor growth rates and
cancer risk - Science Daily, 6/14/11 - "The
first diet, a typical Western diet, contained about 55 percent carbohydrate,
23 percent protein and 22 percent fat. The second, which is somewhat like a
South Beach diet but higher in protein, contained 15 percent carbohydrate,
58 percent protein and 26 percent fat. They found that the tumor cells grew
consistently slower on the second diet ... As well, mice genetically
predisposed to breast cancer were put on these two diets and almost half of
them on the Western diet developed breast cancer within their first year of
life while none on the low-carbohydrate, high-protein diet did.
Interestingly, only one on the Western diet reached a normal life span
(approximately 2 years), with 70 percent of them dying from cancer while
only 30 percent of those on the low-carbohydrate diet developed cancer and
more than half these mice reached or exceeded their normal life span ...
tumor cells, unlike normal cells, need significantly more glucose to grow
and thrive. Restricting carbohydrate intake can significantly limit blood
glucose and insulin, a hormone that has been shown in many independent
studies to promote tumor growth in both humans and mice"

Inverse
association between serum phospholipid oleic acid and insulin resistance in

"oleic acid (OA) ... By adjusted logistic
regression, including the proportions of other fatty acids known to relate
to IR, the odds ratios (OR) (95% confidence intervals) for IR were 0.75
(0.62-0.92) for 1% increase in OA and 0.84 (0.71-0.99) for 1% increase in
linoleic acid. Other fatty acids were unrelated to IR. When using the
alternate definition of IR, OA remained a significant predictor (0.80
[0.65-0.99]) ... Higher phospholipid proportions of OA relate to less IR,
suggesting an added benefit of increasing olive oil intake within the
Mediterranean diet" - Note: I saw olive oil mayonnaise advertised and
I thought that would be a good way to increase the omega-9 in my diet. When
I read the label in the store, olive oil was the main ingredient however it
had three omega-6 oils listed after that so I’m sure it had much more
omega-6 than omega-9. Bottom line, I started making my own omega-9 mayo. See

A1c Levels: Is Lower
Always Better? - Medscape, 4/23/10 - "A1c values
in the lowest decile (median, 6.4%) were associated with an increased risk
for mortality for all patients (hazard ratio [HR], 1.52; 95% confidence
interval [CI], 1.40-1.64). This finding was stronger in the INS cohort (HR,
1.79; 95% CI, 1.45-1.22) than in the SUMET cohort (HR, 1.30; 95% CI,
1.07-1.58). Only the 10th decile (median, 10.4%) was also associated with
increased mortality risk in the SUMET cohort (HR, 1.93; 95% CI, 1.55-2.42);
but in the INS cohort, deciles 2 (median, 6.95%; HR,1.45; 95% CI,

1.49-2.17) were all associated with greater risk. The combined model yielded
results similar to the INS cohort, and the inclusion of a variable for
membership in the INS cohort was significantly associated with increased
mortality (HR, 1.49; 95% CI, 1.39-1.59). The adjusted risk for progression
to large-vessel disease had the same general U-shaped association as for
all-cause mortality, and insulin treatment was associated with an increased
risk for a first large-vessel disease event"

Metformin and incident breast cancer among diabetic women: a
population-based case-control study in Denmark - Cancer Epidemiol
Biomarkers Prev. 2010 Nov 30 - "Metformin users were
less likely to be diagnosed with breast cancer (OR=0.77; 95% CI=0.61, 0.99)
than non-metformin users. Adjusting for diabetes complications, clinically
diagnosed obesity, and important predictors of breast cancer did not
substantially alter the association (OR=0.81; 95%CI=0.63, 0.96). CONCLUSION:
Our results suggest that metformin may protect against breast cancer in type
2 diabetic peri- or postmenopausal women. Impact: This study supports the
growing evidence of a role for metformin in breast cancer chemoprevention"

Dietary patterns may be linked to increased colorectal cancer risk in women
- Science Daily, 10/24/11 - "High red meat intake,
fish intake, sugar-sweetened beverage intake, but low coffee, whole grains
and high-fat dairy intake, when taken as a whole, seemed to be associated
with higher levels of C-peptide in the blood ... C-peptide is a marker of
insulin secretion that can be measured in a person's blood. High levels of
insulin may promote cell growth and multiplication. One of the major
characteristics of cancer is aberrant cell growth. Higher levels of
C-peptide, and therefore insulin, may promote cancer cell growth ... Colon
cancer seems to be one of the cancers that are sensitive to insulin ...
women who most often consumed high amounts of red meat, fish and
sugar-sweetened beverages and low amounts of high-fat dairy, coffee and
whole grains had a 35 percent increased risk for colorectal cancer"

Insulin used to treat diabetes may be linked to increased cancer risk,
review suggests - Science Daily, 3/2/10 -
"Research suggests that metformin, which is used to treat some patients with
diabetes, may provide a protective effect, while insulin and/or certain
insulin analogues may promote tumour growth ... Diabetic patients were 30
per cent more likely to develop colorectal cancer ... Women with diabetes
had a 20 per cent greater risk of developing breast cancer ... People with
diabetes had an 82 per cent higher risk of developing pancreatic cancer"
- Note: I think it's like what came first the chicken or the
egg. I don't believe they know whether it's the insulin or the high
blood sugar. This seems to support that it's the high insulin.

Pioglitazone
attenuates prostatic enlargement in diet-induced insulin-resistant rats by
altering lipid distribution and hyperinsulinemia - Br J Pharmacol. 2010 Aug
19 - "Increased incidence of benign prostatic hyperplasia among
insulin-resistant individuals suggest a role for hyperinsulinemia in prostatic
enlargement ... High fat diet led to the accumulation of fat in non-adipose
tissues, insulin resistance, compensatory hyperinsulinemia and prostatic
enlargement in rats. Pioglitazone treatment altered fat distribution, improved
insulin-sensitivity and normalized lipid and insulin level in rats on the
high-fat diet. The improved metabolic parameters led to decreased cellular
proliferation and increased apoptosis in the prostate gland. High-fat diet
feeding and pioglitazone treatment did not change plasma testosterone levels.

Discovering Pathways of Sarcopenia in Older Adults: A Role for Insulin
Resistance on Mitochondria Dysfunction - J Nutr Health Aging.
2011;15(10):890-895 - "there is a strong evidence
for muscle loss due to insulin resistance as well as mitochondrial
dysfunction over aging. Considering that epidemiological studies have
underlined that insulin resistance may have a specific role on skeletal
muscle fibre atrophy and mitochondrial dysfunction has also been extensively
shown to have a pivotal role on muscle loss in older persons, a combined
pathway may not be ruled out. Considering that there is growing evidence for
an insulin-related pathway on mitochondrial signaling, we hypothesize that a
high degree of insulin resistance will be associated with the development of
sarcopenia through specific alterations on mitochondrial functioning"

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"

Calorie restriction: Scientists take important step toward 'fountain of
youth' - Science Daily, 12/26/09 - "They found
that the normal cells lived longer, and many of the precancerous cells died,
when given less glucose. Gene activity was also measured under these same
conditions. The reduced glucose caused normal cells to have a higher
activity of the gene that dictates the level of telomerase, an enzyme that

Prehypertension is associated with insulin resistance - QJM. 2009 Aug 7
- "All subjects received a 75-g oral glucose
tolerance test (OGTT) for the measurements of IR. RESULTS: The
prehypertensive subjects were more obese and had higher levels of fasting
triglycerides and 2-h insulin than the normotensives. The subjects with
prehypertension were more insulin resistant than the counterparts, indicated
by lower insulin sensitivity index, ISI(0,120), values. While there was no
difference between the two groups in insulin response of OGTT after
adjustments for confounders, the prehypertension group maintained
significant between-group differences in glucose response even when the
incremental insulin levels were added to covariates for adjustments.
DISCUSSION: Our data show that prehypertension is associated with IR. The
subjects with prehypertension have clinical characteristics of the IR
syndrome. It seems that the prehypertension group cannot handle oral glucose
challenge as well as the normotension, probably a consequence of IR in
prehypertension"

Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication -
Science Daily, 9/24/09 - "in an animal study, a
diabetes drug that promotes insulin sensitivity slowed the progression of
muscle wasting and fat loss, the main consequences of a syndrome called
cachexia ... Research suggests that cachexia is responsible for between
one-fifth and one-third of all cancer deaths ... These data provide evidence
that in mice with colon cancer tumors, insulin resistance may be involved in
the development of cachexia rather than occur as a result of cachexia ...
Within eight days, the mice with cancer receiving the rosiglitazone showed
more sensitivity to insulin than did the mice with tumors that received no
medication. The insulin sensitivity of the medicated mice matched that of
mice without tumors ... In addition to stopping fat and muscle loss, the
rosiglitazone also dramatically reduced two biological markers present when
proteins break down, particularly in muscles, and a third marker that
indicates cells are eating their own amino acids in an attempt to survive"

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

have shown that intensive lifestyle intervention could reduce the
progression of IGT to diabetes by 58%. Furthermore, four currently-available
drugs have been established as being effective in preventing diabetes in
subjects with prediabetes. The Diabetes Prevention Program revealed that
metformin 850 mg b.i.d. reduced the risk of diabetes by 31%. The STOP-NIDDM
(Study To Prevent Non-Insulin-Dependent Diabetes Mellitus) trial (n = 1429)
showed that acarbose 100 mg t.i.d. with meals decreased the incidence of
diabetes by 36% when the diagnosis was based on 2 oral glucose tolerance
tests. The XENDOS (Xenical in the Prevention of Diabetes in Obese Subjects)
study examined the use of orlistat, an antiobesity drug, as an adjunct to an
intensive lifestyle modification program in obese non-diabetic subjects.
Orlistat treatment resulted in a 37% decline in the development of diabetes.
More recently, the DREAM (Diabetes Reduction Assessment with Ramipril and
Rosiglitazone Medication) study (n = 5269) demonstrated that rosiglitazone
at 8 mg once/day in subjects with prediabetes (IGT and/or impaired fasting

early peak flow rate (P=0.047) and left ventricular compliance. Pioglitazone
versus metformin increased myocardial glucose uptake (P<0.001), but
pioglitazone-related diastolic improvement was not associated with changes
in myocardial substrate metabolism. Metformin did not affect myocardial
function but decreased cardiac work relative to pioglitazone (P=0.006), a

Vinegar may help dieters eat less - Nutra USA, 9/7/05 -
"Both glucose and insulin responses were
about 25 per cent lower at 90 minutes when the volunteers had consumed the
highest level of vinegar compared to the reference meal ... This level of
vinegar is equivalent to about two to three tablespoons" - See
Vinegar products at iHerb
(1 - 500 mg tablet equals 2 tsb of vinegar.
4.5 tablets equals about 3 tablespoons by my calculations).
- Androgens, Insulin Resistance and Vascular Disease in Men - Medscape,
9/8/05 - "Studies in healthy men
have shown an inverse correlation between testosterone and insulin levels
... physiological testosterone replacement improves insulin sensitivity ...
Insulin resistance also plays a role in the development of atherosclerosis
and hypertension ... hypotestosteronaemia is associated with insulin
resistance in men. Testosterone treatment inhibits the hyperinsulinaemia and
thus may delay the onset of diabetes mellitus in men or even improve
glycaemic control"

Glycemic Control and Coronary Heart Disease Risk in Persons With and Without
Diabetes: The Atherosclerosis Risk in Communities Study - Arch Intern
Med. 2005;165:1910-1916 - "In adults
with diabetes, the relative risk (RR) of CHD was 2.37 (95% confidence
interval [CI], 1.50-3.72) for the highest quintile of HbA1c level compared
with the lowest after adjustment for CHD risk factors ... Elevated HbA1c
level is an independent risk factor for CHD in persons with and without
diabetes"

High Blood Sugar Levels a Risk Factor for Heart Disease
- Doctor's Guide, 9/14/05 - "Lowering blood sugar levels could reduce the risk of
coronary heart disease in both diabetics and non-diabetics ... Non-diabetic
persons with HbA1c levels of 6% or higher had almost a two-fold greater
heart disease risk compared to persons with an HbA1c level below 4.6%"

Normal Fasting Plasma Glucose Levels and Type 2 Diabetes in
Young Men - N Engl J Med. 2005 Oct 6;353(14):1454-62 -
"A multivariate
model, adjusted for age, family history of diabetes, body-mass index,
physical-activity level, smoking status, and serum triglyceride levels,
revealed a progressively increased risk of type 2 diabetes in men with
fasting plasma glucose levels of 87 mg per deciliter (4.83 mmol per liter)
or more, as compared with those whose levels were in the bottom quintile
(less than 81 mg per deciliter"
- Hypertension and Insulin Resistance in the Metabolic Syndrome -
Medscape, 10/10/05 - "As observed in
animal studies, insulin-sensitizing medications may play a potential role in
the reduction of blood pressure. Metformin treatment of spontaneously
hypertensive rats decreased blood pressure by 34 mmHg but had no effect on
the blood pressure of normotensive rats.[9] Pioglitazone prevents
hypertension in the Dahl salt-sensitive rats,[10] and rosiglitazone prevents
development of hypertension in insulin-resistant rats"
- Pancreatic Cancer
Tied to Insulin Woes - WebMD, 12/13/05 -
"Some of the men's blood samples
showed higher levels of blood glucose, insulin resistance, and high insulin
levels. Those men were more likely to later develop pancreatic cancer than
those without insulin problems"

Calories Seen Outweighing Sugar as Diabetes Risk - Vital Choices
Newsletter, 1/1/07 - "they found no
link between consumption of sweetened beverages and the risk of developing
diabetes ... men who drank four or more cups of coffee a day cut their risk
of developing type-2 diabetes by more than 23 percent ... while a high sugar
intake may not by itself cause diabetes, it can certainly be a major
contributing factor to weight gain and obesity: factors that clearly do
promote diabetes" - [Abstract
