D reduces deposition of advanced glycation end-products in the aortic wall
and systemic oxidative stress in diabetic rats - Diabetes Res Clin Pract.
2013 Mar 20 - "Vitamin D may have an important role
in reducing the risk of cardiovascular disease. Advanced glycation
end-products (AGEs) such as Ne-(carboxymethyl)lysine (CML), have been
implicated in diabetic vascular complications via oxidative stress-mediated
pathways ... Untreated diabetes was associated with significantly elevated
CML levels in the aortic wall (19.5±3.3 vs 10.2±4.7ng/mL), increased liver
OSI (6.8±1.9 vs 3.1±0.7), and reduced serum TAC (0.4±0.1 vs 0.8±0.3mmol
Trolox/L), in comparison with the control group. Cholecalciferol
significantly blocked the accumulation of CML in the aortic wall (10.4±8.4
vs 19.5±3.3ng/mL), decreased liver OSI (4.2±1.4 vs 6.8±1.9), and improved
serum TAC (1.0±0.2 vs 0.4±0.1mmol Trolox/L), compared with the untreated

Eating deep-fried food linked to increased risk of prostate cancer -
Science Daily, 1/28/13 - "men who reported eating
French fries, fried chicken, fried fish and/or doughnuts at least once a
week were at an increased risk of prostate cancer as compared to men who
said they ate such foods less than once a month ... In particular, men who
ate one or more of these foods at least weekly had an increased risk of
prostate cancer that ranged from 30 to 37 percent. Weekly consumption of
these foods was associated also with a slightly greater risk of more
aggressive prostate cancer ... Deep frying may trigger formation of
carcinogens in food ... Foods cooked with high heat also contain high levels
of advanced glycation endproducts, or AGEs, which have been associated with
chronic inflammation and oxidative stress. Deep-fried foods are among the
highest in AGE content. A chicken breast deep fried for 20 minutes contains
more than nine times the amount of AGEs as a chicken breast boiled for an
hour, for example"
Crusty foods may worsen heart problems associated with diabetes -
Science Daily, 10/22/12 - "We see evidence that
cooking methods that create a crust -- think the edge of a brownie or the
crispy borders of meats prepared at very high temperatures -- produce
advanced glycation end products (AGEs). And AGEs are associated with plaque
formation, the kind we see in cardiovascular disease ... people with higher
rates of cardiovascular complications ate more of these glycated products.
For each unit increase in AGEs intake, a study participant was 3.7 times
more likely to have moderate to high risk for cardiovascular disease ...
Boiling or stewing meat would reduce your AGEs intake further. And
scrambling an egg with cooking spray instead of frying it leads to a
significant reduction in AGEs"

Stop grilling dinner: Specific toxic byproduct of heat-processed food leads
to increased body weight and diabetes, mouse study finds - Science
Daily, 8/20/12 - "mice with sustained exposure to
the compound, methyl-glyoxal (MG), developed significant abdominal weight
gain, early insulin resistance, and type 2 diabetes. MG is a type of
advanced glycation endproduct (AGEs), which is produced when food is cooked
with dry heat. AGEs have been found to lower the body's protective
mechanisms that control inflammation ... In the study, one group of mice was
fed a diet high in MG over four generations, while the control group was fed
a diet without MG ... Over four generations, the mice that ate the MG
started to develop early insulin resistance and increased body fat, whereas
the control group did not have either of these conditions. The researchers
found that MG caused a marked deficiency in protective mechanisms, such as
the survival factor SIRT1 that is present in fat and controls inflammation,
while enhancing the metabolism of glucose and insulin. The ingestion of MG
also adversely affected the activity of an important anti-AGE receptor
called AGER1, which protects SIRT1 and fights insulin resistance ...
clinical guidelines be revised to eliminate foods cooked using dry heat and
replace them with methods that use lower heat or lots of moisture (water) as
in stewing, poaching or steaming. Examples from the AGE-less diet include
stewed beef, chicken and fish instead of grilled meats"

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
Inhibition of advanced glycation end-product formation on eye lens protein
by rutin - Br J Nutr. 2011 Aug 25:1-9 -
"Formation of advanced glycation end products (AGE) plays a key role in the
several pathophysiologies associated with ageing and diabetes, such as
arthritis, atherosclerosis, chronic renal insufficiency, Alzheimer's
disease, nephropathy, neuropathy and cataract. This raises the possibility
of inhibition of AGE formation as one of the approaches to prevent or arrest
the progression of diabetic complications. Previously, we have reported that
some common dietary sources such as fruits, vegetables, herbs and spices
have the potential to inhibit AGE formation. Flavonoids are abundantly found
in fruits, vegetables, herbs and spices, and rutin is one of the commonly
found dietary flavonols. In the present study, we have demonstrated the
antiglycating potential and mechanism of action of rutin using goat eye lens
proteins as model proteins. Under in vitro conditions, rutin inhibited
glycation as assessed by SDS-PAGE, AGE-fluorescence, boronate affinity
chromatography and immunodetection of specific AGE. Further, we provided
insight into the mechanism of inhibition of protein glycation that rutin not
only scavenges free-radicals directly but also chelates the metal ions by
forming complexes with them and thereby partly inhibiting post-Amadori
formation. These findings indicate the potential of rutin to prevent and/or
inhibit protein glycation and the prospects for controlling AGE-mediated
diabetic pathological conditions in vivo" - See

not an apple a day after all -- it's strawberries: Flavonoids could
represent two-fisted assault on diabetes and nervous system disorders -
Science Daily, 6/27/11 - "fisetin, a
naturally-occurring flavonoid found most abundantly in strawberries and to a
lesser extent in other fruits and vegetables, lessens complications of
diabetes. Previously, the lab showed that fisetin promoted survival of
neurons grown in culture and enhanced memory in healthy mice ... Mice fed a
fisetin-enriched diet remained diabetic, but acute kidney enlargement-or
hypertrophy-seen in untreated mice was reversed, and high urine protein
levels, a sure sign of kidney disease, fell. Moreover, fisetin ingestion
ameliorated anxiety-related behaviors seen in diabetic mice ... blood and
brain levels of sugars affixed to proteins known as advanced glycation
end-products-or AGEs-were reduced in fisetin-treated compared to untreated
Akita mice. These decreases were accompanied by increased activity of the
enzyme glyoxalase 1, which promotes removal of toxic AGE precursors ...
substantial evidence implicates high blood AGE levels with many if not most
diabetic complications ... excessively high AGE levels also correlate with
inflammatory activity thought to promote some cancers. In fact, studies
published by others confirm that fisetin decreases tumorigenicity of
prostate cancer cells both in culture and in animal models ... humans would
have to eat 37 strawberries a day ... Rather than through diet, Maher
envisions that fisetin-like drugs could be taken as a supplement"

Inhibition of the receptor for advanced glycation endproducts (RAGE)
protects pancreatic β-cells - Biochem Biophys Res Commun. 2010 Nov 24 -
"Advanced glycation endproducts (AGEs) and the
receptor for AGEs (RAGE) have been linked to the pathogenesis of diabetic
complications, such as retinopathy, neuropathy, and nephropathy. AGEs may
induce β-cell dysfunction and apoptosis, another complication of diabetes
... Inhibition of RAGE prevented AGE-induced pancreatic β-cell apoptosis,
but could not restore the function of glucose stimulated insulin secretion
(GSIS) in rat islets. In summary, the results of the present study
demonstrate that AGEs are integrally involved in RAGE-mediated apoptosis and
impaired GSIS dysfunction in pancreatic β-cells. Inhibition of RAGE can
effectively protect β-cells against AGE-induced apoptosis, but can not
reverse islet dysfunction in GSIS"

Nutrition and aging skin: sugar and glycation - Clin Dermatol. 2010
Jul-Aug;28(4):409-11 - "The effect of sugars on
aging skin is governed by the simple act of covalently cross-linking two
collagen fibers, which renders both of them incapable of easy repair.
Glucose and fructose link the amino acids present in the collagen and
elastin that support the dermis, producing advanced glycation end products
or "AGEs." This process is accelerated in all body tissues when sugar is
elevated and is further stimulated by ultraviolet light in the skin. The
effect on vascular, renal, retinal, coronary, and cutaneous tissues is being
defined, as are methods of reducing the glycation load through careful diet
and use of supplements"
Glycation End Products in Foods and a Practical Guide to Their Reduction in
the Diet - J Am Diet Assoc. 2010 Jun;110(6):911-916.e12 -
"Modern diets are largely heat-processed and as a
result contain high levels of advanced glycation end products (AGEs).
Dietary advanced glycation end products (dAGEs) are known to contribute to
increased oxidant stress and inflammation, which are linked to the recent
epidemics of diabetes and cardiovascular disease ... Based on the findings,
dry heat promotes new dAGE formation by >10- to 100-fold above the uncooked
state across food categories. Animal-derived foods that are high in fat and
protein are generally AGE-rich and prone to new AGE formation during
cooking. In contrast, carbohydrate-rich foods such as vegetables, fruits,
whole grains, and milk contain relatively few AGEs, even after cooking. The
formation of new dAGEs during cooking was prevented by the AGE inhibitory
compound aminoguanidine and significantly reduced by cooking with moist
heat, using shorter cooking times, cooking at lower temperatures, and by use
of acidic ingredients such as lemon juice or vinegar"

"Carnosine distinctly improved the appearance of the aged mice, whose coat fullness and color remained much closer to that of young animals. Significantly more carnosine-treated mice had
glossy coats (44% vs. 5%), while significantly fewer had skin ulcers (14% vs. 36%) . . . .The sharpest contrast between the treated and untreated mice was seen in their behavior. Only 9% of the untreated mice displayed normal behavioral reactivity, compared to 58% of the carnosine treated mice."

"The formation of AGE happens in everyone and is a major factor in the aging process itself. These damaged proteins may lead to premature signs of aging (wrinkles and brown
spots) and in the long run to damaging effects on most organ systems within the body . . . The amino acid carnosine is a natural AGE inhibitor found in high concentrations in the brain, muscle tissue and the lens of the human eye. It is also known to be an antioxidant capable of protecting cell membranes and other
cell structures. In vitro studies demonstrated that carnosine inhibits glycosylation and crosslinking of proteins induced by reactive aldehydes, and that it is effective in reducing AGE formation by competing with proteins for binding with the sugars. The authors suggest that this nontoxic compound should be
explored in the treatment of such conditions as diabetic complications, inflammatory disorders, alcoholic liver disease and possibly Alzheimer's disease."

"Free arginine has been shown to help prevent a destructive process known as
cross-linking, which is associated with accelerated aging. Excessive cross-linking reactions inevitably damage the kidneys, necessitating dialysis in advanced age"

"Diabetics and others who become susceptible to high levels of glucose in blood serum as they age
suffer from the formation of deleterious hybrid protein-sugar complexes known as advanced glycation end products (AGE) ... ALC decreased the glycation by 42%"

"One feature of aging and of diabetes is increased stiffness of blood vessels, such as the carotid artery in the neck. Egan showed that in rats, the distensibility of the carotid artery falls by more than
50 percent between 24 and 30 months of age in control animals, but falls by less than 7 percent in animals that received 50 mg/kg of Pimagedine in their drinking water. Further, over the same age interval, the rat heart-weight-to-body-weight ratio rose by about 50 percent in control animals, indicating heart
failure; but the same ratio rose by less than about 7 percent in animals treated with Pimagedine. Pimagedine also normalized left ventricular stiffness and the amount of sugar attached to collagen (connective tissue protein). These are huge anti-aging effects.
But as good as Pimagedine is, ALT-711 may be a great deal better. ALT-711 is something called an "alpha dione cleaving agent." While Pimagedine prevents permanent glucose-protein crosslinks from forming, ALT-711 reverses glucose-protein crosslinks after they have formed. Still better, ALT-711 acts like an artificial
enzyme, breaking crosslink after crosslink without itself being consumed in the reaction. It is as if ALT-711 were a "reverse free radical," setting up a chain reaction of positive, rather than negative, chemical reactions.""
