Rerouting Mechanisms: Polyol Pathway And Macromolecules Glycation
Aside from ROS generated through mitochondrial failure, hyperglycemia may trigger the onset of oxidative stress via pathways that dwell upstream the glycolytic enzyme GAPDH .
As previously discussed, free glucose is present in the cytosol of neurons and its concentrations rise during hyperglycemia leading to glucotoxicity. Under normal circumstances, hexokinase is mandated to transform available glucose into glucose 6-phosphate. However, due to substrate-mediated inhibition, in hyperglycemic conditions, it can only funnel a fraction of cytosolic glucose toward the glycolytic pathway before becoming saturated. Excess glucose is therefore consumed by other pathways and is constantly replenished by high extracellular levels. The principal compensatory outlets are the polyol pathway and macromolecule glycation which are two key pathways through which glucotoxicity manifests .
AGEs may also occur extracellularly or being directly secreted from the cells in which they are generated to induce oxidative stress and inflammation in a variety of cells . AGEs trigger oxidative stress by binding their cognate membrane receptor, the RAGE and activating downstream mediators know to induce oxidative stress, such as the inducible nitric oxide synthase . Nevertheless, despite AGEs being described for their ability to promote oxidative stress in peripheral tissues , their role in oxidative stress in PD remains to be elucidated.
Carbohydrate Quality And The Glycemic Index
As we continue to learn about the role of nutrition in health, it has become clear that the quality of the nutrients we ingest not just the amount matters. While imperfect, the Glycemic Index can be useful for characterizing the nutritional quality of a given carbohydrate.
The Glycemic Index ranks carbohydrate-containing foods on a scale from 0 to 100 according to their potential to boost blood sugar. High GI foods cause sharp spikes in blood sugar and insulin levels. Foods with a low GI are generally digested and absorbed more slowly, and therefore cause a gentler rise in blood sugar and insulin. See how different carbohydrates stack up on this Glycemic Index Reference Chart.
High GI foods include starchy vegetables and highly processed carbohydrates in short, the ones we already know arent beneficial for our health. By contrast, low GI foods tend to be fiber-rich fruits, non-starchy vegetables, legumes and minimally or un-processed whole grains.
Diabetes Linked To Parkinsons Disease
Type 2 Diabetes May Raise Parkinsonâs Disease Risk
Finnish researchers have found that people with type 2 diabetes were more than 80% more likely to be later diagnosed with Parkinsonâs disease than others.
Itâs the first major prospective study to suggest that diabetes may be a risk factor of Parkinsonâs disease, a progressive disease that causes muscle rigidity and tremors.
Researchers say the exact nature of the relationship between diabetes and Parkinsonâs disease is unclear, but several lifestyle factors may be associated with both disorders, such as being overweight, cigarette smoking, and lack of physical activity.
âIt could be hypothesized that diabetes might increase the risk of Parkinsonâs disease partly through excess body weight,â writes researcher Gang Hu, MD, PhD, of the National Public Health Institute in Finland, and colleagues in Diabetes Care.

Optimise Your Diet Reduce Your Toxic Load
While the cause of Parkinsons is not known, environmental toxins such as pesticides and herbicides are implicated. Researchers have found levels of these chemicals to be higher in the brains of Parkinsons sufferers and incidence of Parkinsons is higher in areas with greater use of these chemicals. It makes sense to avoid any environmental toxins that you can. Also, consider your intake of dietary toxins such as alcohol and caffeine avoiding or reducing these may reduce the load on your bodys detoxification pathways.
Parkinsons Disease And Insulin Resistance
All Science News articles summarize a research study and are not an official opinion, endorsement or position of the Parkinsons Foundations.
Insulin resistance is a precursor to type-2 diabetes a disease that occurs when your blood glucose is too high. First suggested in the 1960s, a growing number of studies are finding links between Parkinsons disease and T2D. And contrary to popular belief, you neednt be overweight to have IR. In fact, having IR usually has no symptoms which is why it often goes undetected. While researchers dont fully understand what causes IR, we do know that left unmanaged, T2D can lead to serious problems such as heart disease, stroke, nerve damage, eye disease, gum disease, foot problems, bladder problems, sexual problems and, may possibly negatively impact the course of PD.

Dietary Intake Of The Parkinsons Disease Cohort
Impulse Control Disorders
Mean energy intake was significantly greater for PD patients who reported an impulse control disorder compared to those without , after adjusting for age, sex and PD duration . This was mainly attributable to increased consumption of carbohydrates , increased total sugar intake and increased consumption of total fibre by PD patients with an impulse control disorder. Linear regression modelling validated that the increased carbohydrate and total sugar consumption in impulse control disorder patients persisted after controlling for patient age, sex and PD duration . PD patients with an impulse control disorder also consumed greater amounts of a variety of vitamins and minerals, as outlined in Supplementary Table 1. When micronutrient intake was assessed per 1,000 kJ energy intake, PD patients with an impulse control disorder compared to PD patients without an impulse control disorder consumed more potassium , more beta carotene and more vitamin C .
Depression
PD patients who were depressed , consumed more added sugars compared to those who were not depressed , after controlling for patient age, sex and PD duration . Interestingly, depressed PD patients consumed less alcohol than those who did not report depression , after controlling for patient age, sex and PD duration .

Parkinsons Disease And Type 2 Diabetes
Wednesday, 5 May 2021
While some research suggests that type 2 diabetes increases the risk of Parkinsons disease, there is no conclusive proof. Many more people live with Parkinsons disease but not diabetes compared to those living with both Parkinsons and diabetes. We know that both Parkinsons disease and type 2 diabetes are more likely as we grow older. Both conditions are due to a progressive loss of hormone production. Parkinsons disease is a loss of dopamine-producing cells, and diabetes is a loss of insulin production and beta cells in the pancreas, in addition to insulin resistance.
Diabetes can have effects on the brain. High glucose levels can damage blood vessels in the brain and thereby increase the risk of stroke. Increased glucose levels and insulin resistance affect contribute to inflammation in the brain. Type 2 diabetes increases the risk of Alzheimers and other dementias.
Parkinsons disease is an inflammatory, progressive condition in the brain. When type 2 diabetes and Parkinsons disease coexist, they may create a destructive environment in the brain.

Can Eating Well Alter The Course Of Pd
Scientists know a lot about the molecular changes that underlie Parkinsons. You may have heard of alpha-synuclein, the protein that forms clumps in brain cells, oxidative stress, mitochondrial dysfunction, and inflammation. The search is intense for therapies that can stop or reverse these processes. Can nutrition or dietary choices do anything to change them or alter the course of PD?
Some laboratory and animal research suggest that diet could have an effect, especially plant-based foods like fruits, vegetables, legumes, nuts and seeds. Every plant-based food contains hundreds of chemicals called phytochemicals. These are not nutrients, but substances that may, alone or in combination, affect many of the processes thought to be involved in PD including oxidation, chronic inflammation, protein aggregation and mitochondrial dysfunction.
Phytochemicals have not been proven to change disease progression in people with PD, but neither is there typically any harm in eating a diet that includes whole, unprocessed plants. This diet has proven benefits for preventing heart and vascular disease and can reduce PD symptoms, like constipation and risk of cognitive change.
Type 2 Diabetes Linked To Increased Risk Of Parkinsons Disease
Genetic data suggests there may be a direct relationship between type 2 diabetes and a higher risk of the movement disorder, as well as its progression, but more studies are needed.
Everyday Health
People managing type 2 diabetes and their doctors may need to have Parkinsons disease on their radar, as new research sheds light on the possible connection between these two chronic health conditions.
For the review and meta-analysis, which was published in March 2021 in Movement Disorders, researchers examined data combined from nine previous studies that followed individuals with type 2 diabetes over time to see if they developed Parkinsons disease. They found type 2 diabetes associated with a 21 percent increased risk of Parkinsons and with faster symptom progression. Parkinsons causes muscle stiffness, tremors, impaired balance, and slow movement, in addition to cognitive and sleep issues, according to the National Institute on Aging.
Yet study authors could not account for the severity of participants type 2 diabetes, and they couldnt determine the effect of diabetes drugs or quality of blood sugar management on Parkinsons disease risk two major limitations.
We found some evidence to support that being the case, Dr. Noyce says. So, we conclude that treatment or prevention of type 2 diabetes may reduce the risk of Parkinson’s or its progression.

Diabetes Boosts Parkinsons Risk
In the study, researchers followed a group of more than 50,000 men and women in Finland over a period of 18 years. During that time, 324 men and 309 women developed Parkinsonâs disease.
Researchers found people who had type 2 diabetes at the start of the study were much more likely to be later diagnosed with Parkinsonâs disease.
Overall, after adjusting for other possible risk factors for Parkinsonâs disease, men and women with type 2 diabetes were 83% more likely to develop Parkinsonâs disease than those without it.
Although common lifestyle factors may play a role, researchers say more study is needed to fully understand the relationship between diabetes and Parkinsonâs disease.

Blood Sugar Levels Appear To Affect Motor Skills In Patients With Parkinsons Disease
Abnormal blood sugar levels, below or above the norm, appear to be linked to faster progression of motor difficulties in people with Parkinsonâs disease, research suggests.
The brief report on this discovery, âEuglycemia indicates a favorable motor outcome in Parkinsonâs disease,»Was published in the journal Movement disorders.
Previous research supports that type 2 diabetes is detrimental to people with Parkinsonâs disease. Severe diabetes has been associated with an increased risk of postural instability and poorer gait, as well as more cognitive problems.
However, few studies follow over longer periods of time the evolution of motor and cognitive disorders as a function of a personâs blood sugar. Researchers at the Karolinska Institute in Sweden and their colleagues conducted a retrospective analysis to assess the correlation between these sugar levels and the progression of motor symptoms and cognitive decline in patients with Parkinsonâs disease.
They analyzed the levels of glycated hemoglobin in the blood of 244 patients enrolled in an observational study at Karolinska University Hospital.
HbA1c is formed when hemoglobin, the protein in red blood cells that carries oxygen, binds to a sugar to become glycated. HbA1c is a standard measure of a personâs average blood sugar over the past 60 days.
Patients were followed for a minimum of two years to a maximum of 26 years.

So What Does Nutrition Have To Do With Parkinsons
1. The neurotransmitter dopamine is made in the body from amino acids which are the building blocks of protein. Every time we eat a protein rich food we take in protein, which the body breaks down into its component amino acids. Two amino acids are converted in the body into L-Dopa, which is then converted into dopamine in the brain.
2. Nutrient co-factors are required for each stage of this conversion process, so deficiencies of these may reduce dopamine production.
3. L-dopa medication competes for absorption with dietary amino acids, therefore the timing of taking L-dopa and the eating of protein needs to be managed for optimal absorption and effectiveness of the drug and the reduction of side-effects.
Therefore, the nutritional therapy approach to Parkinsons includes:
1. Supporting dopamine production by ensuring adequate precursors and co-factors
2. Considering drug-nutrient interactions to enhance effectiveness and reduce side-effects
3. Optimising nutritional status and addressing co-morbidities . These co-morbidities include constipation, depression, fatigue, and insomnia.

Blood Sugar And Cancer Link
In a study in JAMA, researchers found that people with the highest fasting blood sugar levels had higher mortality.
Even after controlling for smoking and alcohol use, they found that those with the highest fasting blood sugar levels had higher mortality rates from all cancers studied as compared to those with the lowest fasting blood sugar levels .
This relationship was strongest for pancreatic cancer in both men and women, though there were also significant associations for other types of cancer.

Parkinsons Disease And Avoiding Sugar Miraburst
If you, or a loved one, suffers from Parkinsons Disease you may have heard to avoid sugar to help alleviate symptoms and decrease chances of exacerbation of the disease.
To quote Dr. Beckie Port, in an article published online on August 5, 2020:
Research has linked sugar and Parkinsons in a number of ways:
- An increase in sugar cravings may be a side effect of the types of microorganisms that live in our gut that can change in people with Parkinsons.
- Some people report that eating sugary foods makes their Parkinsons symptoms worse but this has yet to be proven through scientific research.
- Diabetes has been shown to increase the risk of neurodegenerative conditions including Parkinsons.
Research into the impact of diabetes both type 1 and type 2 on the brain is a hot topic and the potential connection to Parkinsons is becoming clearer.
High blood sugar levels can cause the brain to age and shrink. It can also lead to small-vessel disease reducing blood flow to the brain and increasing the risk of vascular dementia.
Enter MiraBurst tablets! These quick-melt tablets dissolved on your tongue prior to eating or drinking can help satisfy those sugar cravings.
Imagine the possibilities! Mojitos without sugar taste just as good. Lemon meringue pie even better than before. Even raw cranberries taste like candy. Your recipes are only limited to your imagination!

Low Risk Seen For Second Allergic Reaction To Mrna Covid
TUESDAY, Feb. 22, 2022 — You don’t need to run marathons or sweat it out on your indoor bike to boost your heart health.
This is the main message of a new study that found everyday household activities including dishwashing, gardening and cooking also count when it comes to helping older women reduce their risk for heart disease.
Women who got at least four hours of such daily life movement had a 43% lower risk of heart disease, a 30% lower risk of stroke, and a 62% lower risk of dying from heart disease compared to women who clocked fewer than two hours each day.
“The paradigm-shifting aspect is that we don’t typically call a lot of these activities strenuous exercise, but your heart doesn’t care what we call them, it knows when your body is moving and responds,” said study co-author Andrea LaCroix. She is a professor and chief of epidemiology at the University of California, San Diego School of Public Health and Human Longevity Science.
Just like walking and other forms of exercise, daily life movement improves blood pressure, blood sugar and cholesterol, and it helps maintain a normal weight, all of which will boost heart health, added study author Steve Nguyen, a postdoctoral scholar at UCSD.
For the study, more than 5,400 women wore a device for up to a week to track how much time they spent sitting, sitting in a vehicle, standing still, engaging in daily life movements, walking or running. Computer algorithms helped researchers classify this data.

High blood sugar levels can cause the brain to age and shrink. It can also lead to small-vessel disease reducing blood flow to the brain and increasing the risk of vascular dementia.
These effects are so significant that scientists are developing ways to try to combat the neurological consequences of diabetes. In America, researchers are testing if nasal sprays containing insulin can boost the areas of the brain associated with memory. Results showing improved cognition in healthy volunteers have begun attracting attention in Alzheimers research.
Our results indicate that diabetes promotes striatal oxidative stress, alters dopamine neurotransmission, and increases vulnerability to neurodegenerative damage leading to motor impairment. Iara PérezTaboadaet al., 2020. Movement Disorders
