A Fructose Damage Blood Test?

HbA1c sugar damaged blood protein – are we measuring the
most important thing.?

Whilst I have no doubt that measuring this is a great way to
detect potential sugar damage, it may only be the tip of the iceberg.

Fructose damage should be measured. Fructose has been
increasing in our foods since the now discredited ‘low-fat high-sugar’ food
fads hit the markets almost 40 years ago.

On a ‘High-Fat Low-Car’ regime I have found that keeping below
70mmol/mol (6%) has prevented all obvious diabetes symptoms from developing.

Avoiding refined Fructose products may be most important
because Fructose is 7x more reactive and damaging towards the bodies protein
mechanisms and enzymes.  The benefits of
avoiding high-fructose foods (HFCS on labels) may be many times greater than
simply managing glucose for modern type 2 diabetics if over the last 40 years HFCS
fructose additives are 7x more dangerous than glucose when it come to sugar damage!

We urgently need
to routinely test for Fructose damage in a blood test!

Autoimmunity and T2D

My anecdotal experience and studies have shown me thIs:-

Glycoproteins are important on cell surfaces (extracellular matrix) they are anchored by dolichols and form an important part of the communication between tissue and immune system, with recognisable sequences of sugars deliberately assembled for the matrix. This is structural sugars in the body assembled by enzymes in the normal cellular machinery.

Glycation damaged proteins (AGE). These are exposed proteins who randomly become attached to a mono-sugar (usually glucose but recently increasingly fructose) attaching to lysine by the maillard reaction).

In cooking at oven temps this is a desirable and flavoursome reaction at some speed.

In diabetics this is a very slow (decades at body temp) degradation of lipid receptor mechanisms, elastins and collagens.

Auto-immunes and T2D

The body has a clean-up immune response to random AGE mono-sugar attack, which is overwhelmed as we age and develop T2D (over decades). The suagr damage effect is present in many tissues showing a strong immune response (arthritis, eczema) which often respond well to carbohydrate restriction and increased dietary use of ‘essential fatty acids’.

The Academy of Medical Royal Colleges Obesity Initiative was launched at a parliamentary reception.  At this reception I was able to confirm with several members of the Steering Group that the submissions of evidence (Appendix B in their report) clearly identified Dietary Sugar as a major contributor to this epidemic of Obesity which has steadily increased since around 1980. 

This was the time when we were ill-advised to eat less fat and eat more sugar generating carbohydrate foods (McGovern & COMA). Ironically it was also the time when the food industry gave us low fat options by replacing healthy fats with cheap unhealthy sugars. A 35 year obesity epidemic has ensued.

Dietary Fat and cholesterol was never a cause of obesity or heart disease. It was always the dietary Sugar particularly Fructose that did the damage.

There were many notable contributors and I commend the following evidence submission (click on names for links)

Key points in our paper are:-

The amyloid-β present in Alzheimer’s plaque may not be causal,
since drug-induced suppression of its synthesis led to further
cognitive decline in the controlled studies performed so far.

• Researchers have identified mitochondrial dysfunction and brain
insulin resistance as early indicators of Alzheimer’s disease.
• ApoE-4 is a risk factor for Alzheimer’s disease, and ApoE is involved
in the transport of cholesterol and fats, which are essential for signal
transduction and protection from oxidative damage.
• The cerebrospinal fluid of Alzheimer’s brains is deficient in fats and
cholesterol.
• Advanced glycation end-products (AGEs) are present in significant
amounts in Alzheimer’s brains.
• Fructose, an increasingly pervasive sweetening agent, is ten times as
reactive as glucose in inducing AGEs.
• Astrocytes play an important role in providing fat and cholesterol to
neurons.
• Glycation damage interferes with the LDL-mediated delivery of fats
and cholesterol to astrocytes, and therefore, indirectly, to neurons.
• ApoE induces synthesis of Aβ when lipid supply is deficient.
• Aβ redirects neuron metabolism towards other substrates besides
glucose, by interferingwith glucose and oxygen supply and increasing
bioavailability of lactate and ketone bodies.
• Synthesis of the neurotransmitter, glutamate, is increased when
cholesterol is deficient, and glutamate is a potent oxidizing agent.
• Over time, neurons become severely damaged due to chronic exposure
to glucose and oxidizing agents, and are programmed for apoptosis
due to highly impaired function.
• Once sufficiently many neurons are destroyed, cognitive decline is
manifested.
• Simple dietary modification, towards fewer highly-processed
carbohydrates and relatively more fats and cholesterol, is likely a
protective measure against Alzheimer’s disease.

Fructose and Dementias

The brain is only 2% of your body mass but it contains 25% of your cholesterol.  The cholesterol is vital to memory formation (synapses)  and nerve protection (myelin).  Our livers make 2.5g of fresh cholesterol every day to replace the losses.  The liver delivers the brains fresh daily supply of cholesterol to the brain in small lipid droplets known as LDL.  The empties return to the liver known as HDL with various waste products for recycling and disposal.

To get these vital supplies into the brain the LDL droplets have to cross the blood-brain barrier. The particles carry a protein label which is recognised by the receptors.  The brains receptors lock onto the LDL and allow the particles to pass though into the brains astrocyte cells. These astrocytes use the cholesterol  and fats in the care and feeding of the neurons and all is well with our thoughts and memories.

If we consume a lot of sugary products, especially fructose, the receptors become damaged by sugary attachments and fail to work.  The LDL then builds up in the blood and the brain is starved of fat and cholesterol.  All is now not well with our thoughts and memories.

This is a simplification of our biochemical papers on this matter. Other organs like the heart are also affected this way. How is it possible for an educated professionals to go on misleading us by referring to LDL as “Bad Cholesterol”?   

Fructose is getting away with murder and the blame is being laid upon the good guys  – fat and cholesterol.

Fructose Has Different Effect Than Glucose On Brain Regions That Regulate Appetite

Jan. 1, 2013 — In a study examining possible factors regarding the associations between fructose consumption and weight gain, brain magnetic resonance imaging of study participants indicated that ingestion of glucose but not fructose reduced cerebral blood flow and activity in brain regions that regulate appetite, and ingestion of glucose but not fructose produced increased ratings of satiety and fullness, according to a preliminary study published in the January 2 issue of JAMA.

Importance  Increases in fructose consumption have paralleled the increasing prevalence of obesity, and high-fructose diets are thought to promote weight gain and insulin resistance. Fructose ingestion produces smaller increases in circulating satiety hormones compared with glucose ingestion, and central administration of fructose provokes feeding in rodents, whereas centrally administered glucose promotes satiety.

Objective  To study neurophysiological factors that might underlie associations between fructose consumption and weight gain.

Design, Setting, and Participants  Twenty healthy adult volunteers underwent 2 magnetic resonance imaging sessions at Yale University in conjunction with fructose or glucose drink ingestion in a blinded, random-order, crossover design.

Main Outcome Measures  Relative changes in hypothalamic regional cerebral blood flow (CBF) after glucose or fructose ingestion. Secondary outcomes included whole-brain analyses to explore regional CBF changes, functional connectivity analysis to investigate correlations between the hypothalamus and other brain region responses, and hormone responses to fructose and glucose ingestion.

Results  There was a significantly greater reduction in hypothalamic CBF after glucose vs fructose ingestion (−5.45 vs 2.84 mL/g per minute, respectively; mean difference, 8.3 mL/g per minute [95% CI of mean difference, 1.87-14.70]; P = .01). Glucose ingestion (compared with baseline) increased functional connectivity between the hypothalamus and the thalamus and striatum. Fructose increased connectivity between the hypothalamus and thalamus but not the striatum. Regional CBF within the hypothalamus, thalamus, insula, anterior cingulate, and striatum (appetite and reward regions) was reduced after glucose ingestion compared with baseline (P < .05 significance threshold, family-wise error [FWE] whole-brain corrected). In contrast, fructose reduced regional CBF in the thalamus, hippocampus, posterior cingulate cortex, fusiform, and visual cortex (P < .05 significance threshold, FWE whole-brain corrected). In whole-brain voxel-level analyses, there were no significant differences between direct comparisons of fructose vs glucose sessions following correction for multiple comparisons. Fructose vs glucose ingestion resulted in lower peak levels of serum glucose (mean difference, 41.0 mg/dL [95% CI, 27.7-54.5]; P < .001), insulin (mean difference, 49.6 μU/mL [95% CI, 38.2-61.1]; P < .001), and glucagon-like polypeptide 1 (mean difference, 2.1 pmol/L [95% CI, 0.9-3.2]; P = .01).

Conclusion and Relevance  In a series of exploratory analyses, consumption of fructose compared with glucose resulted in a distinct pattern of regional CBF and a smaller increase in systemic glucose, insulin, and glucagon-like polypeptide 1 levels.
