Diabetes and dementia risk: More good reasons to keep blood sugar in check

There are many reasons to avoid getting diabetes, or to keep it controlled if you already have it: Higher risks for heart disease, stroke and for having a foot or leg amputation. But here’s another one: It’s a major risk factor for dementia.

While researchers are still investigating what causes that increased risk, one thing they do know is it’s linked to highs – and lows – in the body’s blood sugar levels.

“Whether it’s Type 1 or Type 2 diabetes, glycemic control is very important” for maintaining good brain health, said Rachel Whitmer, chief of the division of epidemiology at University of California, Davis and associate director of the school’s Alzheimer’s Disease Research Center. “This is another motivation to have good control.”

Good management of blood glucose levels is one of seven lifestyle changes people can make to support better heart and brain health, called Life’s Simple 7 by the American Heart Association. It’s a step that could potentially help more than 34.2 million people in the U.S. living with diabetes.

People who have trouble sleeping are at a higher risk of dying – especially people with diabetes

People in the UK with sleep problems are at an increased risk of dying, finds a new study from the University of Surrey and Northwestern University. 

In a paper published by the Journal of Sleep Research, researchers reveal how they examined data* from half a million middle-aged UK participants asked if they had trouble falling asleep at night or woke up in the middle of the night.

The report found that people with frequent sleep problems are at a higher risk of dying than those without sleep problems. This grave outcome was more pronounced for people with Type-2 diabetes: during the nine years of the research, the study found that they were 87 per cent more likely to die of any cause than people without diabetes or sleep disturbances.   

The study also found that people with diabetes and sleep problems were 12 per cent more likely to die over this period than those who had diabetes but not frequent sleep disturbances. 

Malcolm von Schantz, the first author of the study and Professor of Chronobiology from the University of Surrey, said: 

“Although we already knew that there is a strong link between poor sleep and poor health, this illustrates the problem starkly.” 

“The question asked when the participants enrolled does not necessarily distinguish between insomnia and other sleep disorders, such as sleep apnoea. Still, from a practical point of view it doesn’t matter. Doctors should take sleep problems as seriously as other risk factors and work with their patients on reducing and mitigating their overall risk.” 

Professor Kristen Knutson of Northwestern University, the senior co-author of the study, said: 

“Diabetes alone was associated with a 67 per cent increased risk of mortality. However, the mortality for participants with diabetes combined with frequent sleep problems was increased to 87 per cent. In order words, it is particularly important for doctors treating people with diabetes to also investigate sleep disorders and consider treatments where appropriate.”

Eating more fruit and vegetables linked to less stress – study

Eating a diet rich in fruit and vegetables is associated with less stress, according to new research from Edith Cowan University (ECU).

The study examined the link between fruit and vegetable intake and stress levels of more than 8,600 Australians aged between 25 and 91 participating in the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study from Baker Heart and Diabetes Institute.

Diabetes complications in children linked to worse memory, IQ

Diabetic ketoacidosis (DKA), a serious but common complication of type 1 diabetes, is linked to  lower IQ scores and worse memory in children with type 1 diabetes, according to a study led by UC Davis Health researchers. The study published Sept. 22 in Diabetes Care is also the first large-scale work to differentiate between DKA’s impact on children with a new diagnosis and children with a previous diagnosis of type 1 diabetes.

DKA happens when diabetes goes undiagnosed or is poorly managed. With DKA, blood sugar gets very high as acidic substances called ketones build up to dangerous levels in the body. Early signs of DKA include excessive thirst, frequent urination, and nausea, abdominal pain, weakness and confusion.

Pizza study shows body copes surprisingly well with one-off calorie indulgence

A new study, which involved participants eating pizza well after feeling ‘full’ in order to test what immediate effects this had on the body, finds that our metabolism is surprisingly good at coping with over-indulgence.

Thick crust pizza in Chicago

Researchers with the Centre for Nutrition, Exercise and Metabolism at the University of Bath compared the effects of normal eating (i.e. ‘eat until you are comfortably full’) with maximal eating (i.e. ‘eat until you cannot manage another bite’).

They found that the young, healthy men (aged 22 – 37) who volunteered for the trial consumed almost twice as much pizza when pushing beyond their usual limits, doubling their calorie intake, yet, remarkably, managed to keep the amount of nutrients in the bloodstream within normal range.

How Diabetes and Obesity Affect the Brain

With more than 30 million Americans diagnosed with diabetes, and another 87 million diagnosed with obesity, both conditions have become national epidemics. 

The two diseases cause a number of complications, including neuropathy, which causes damage to the peripheral nerves. Neuropathy is characterized by numbness or tingling and can sometimes be accompanied by pain. 

Brian Callaghan, M.D., the Fovette E. Dush associate professor of neurology, has sounded an alarm through his recent clinical research, which has demonstrated that, in addition to peripheral nerve damagediabetes and obesity can also cause cognitive dysfunction, effecting thinking, reasoning or memory. 

Here, Callaghan discusses his latest work and ways to identify and treat the condition:

Does poor air quality add pounds?

Breathing dirty air takes a heavy toll on gut bacteria, boosting risk of obesity, diabetes, gastrointestinal disorders and other chronic illnesses, new University of Colorado Boulder (CU) research suggests.

The study, published online in the journal Environment International, is the first to link air pollution to changes in the structure and function of the human gut microbiome—the collection of trillions of microorganisms residing within us.

The gaseous pollutant ozone, which helps make up Denver’s infamous “brown cloud”—is particularly hazardous, the study found, with young adults exposed to higher levels of ozone showing less microbial diversity and more of certain species associated with obesity and disease.

“We know from previous research that air pollutants can have a whole host of adverse health effects,” said senior author Tanya Alderete, an assistant professor of integrative physiology, pointing to studies linking smog with Type 2 diabetes, weight gain and inflammatory bowel diseases. “The takeaway from this paper is that some of those effects might be due to changes in the gut.”

Body Weight and Heart Health – Tufts

Eat less; move more; live longer remains the mantra of this blog. Following is a super discussion of the relationship between body weight and heart health from Tufts Health & Nutrition Letter.

Human Heart

Excess body weight increases risk for cardiovascular disease (CVD), as well as type 2 diabetes, certain cancers, and many other illnesses. However, not everyone who is overweight or obese develops these illnesses; and simply having a “normal” body weight or body mass index (BMI)-a measure of body weight relative to height-is no guarantee of low risk. “The relationship between BMI and risk for CVD and death is complex,” says Edward Saltzman, MD, academic dean for education at Tufts’ Friedman School of Nutrition Science and Policy. “Elevated BMI does increase CVD risk, but risk is also impacted by things like body-fat percentage, waist circumference, age, duration of obesity, race, ethnicity, gender, and other genetic factors,” as well as lifestyle elements such as smoking and level of physical activity.

Diet and Alzheimer’s – Tufts

Herewith another entry in our arsenal against that destroyer of lives – Alzheimer’s Disease, from the Tufts Health & Nutrition Letter.

Alzheimer’s disease accounts for 60 to 80 percent of the loss of memory and other cognitive abilities collectively known as dementia. There is no known food or diet that can prevent or cure Alzheimer’s dementia, but diet may help delay onset and slow progression.

What sets Alzheimer’s apart from other forms of dementia is the excessive buildup of beta-amyloid protein fragments into plaques, as well as defective tau proteins that form tangles in the brain. These changes lead to the death of the nerve cells responsible for everything from memory to movement. There are currently no known dietary factors that can impact the formation of these plaques and tangles, but diet may act in other ways to influence Alzheimer’s and other forms of dementia.

What are the benefits of lion’s mane mushrooms?

Truth be told I never heard of Lion’s mane mushrooms before today. However, this article in Medical News Today piqued my curiosity. I would like to hear from any readers who may have had experience with the mushrooms in one form or another.

Screen Shot 2020-02-20 at 9.35.49 PM.png

Lion’s mane mushrooms (Hericium erinaceus) are white, globe-shaped fungi that have long, shaggy spines. People can eat them or take them in the form of supplements. Research suggests that they may offer a range of health benefits, including reduced inflammation and improved cognitive and heart health. Continue reading

America’s most widely consumed oil causes genetic changes in the brain – Study

New University of California Riverside research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer’s disease, anxiety, and depression.

Edible fats and oil consumed in the U.S. Source: USDA

Used for fast food frying, added to packaged foods, and fed to livestock, soybean oil is by far the most widely produced and consumed edible oil in the U.S., according to the U.S. Department of Agriculture. In all likelihood, it is not healthy for humans.

It certainly is not good for mice. The new study, published this month in the journal Endocrinology, compared mice fed three different diets high in fat: soybean oil, soybean oil modified to be low in linoleic acid, and coconut oil. Continue reading

Overspill of stored fat shown to cause Type 2 Diabetes

The study involved a group of people from Tyneside who previously had Type 2 diabetes but had lost weight and successfully reversed the condition as part of the DiRECT trial, which was funded by Diabetes UK and led by Professors Roy Taylor and Mike Lean (Glasgow University).

WeightLoss_web_1024.jpg

The majority remained non-diabetic for the rest of the two year study, however, a small group went on to re-gain the weight and re-developed Type 2 diabetes.

Professor Roy Taylor, from the Newcastle University Institute of Translational and Clinical Research, explained what the advanced scanning techniques and blood monitoring revealed.

He said: “We saw that when a person accumulates too much fat, which should be stored under the skin, then it has to go elsewhere in the body. The amount that can be stored under the skin varies from person to person, indicating a ‘personal fat threshold’ above which fat can cause mischief.

When Fathers Exercise, Children Are Healthier, Even As Adults – Study

Exercise appears to be a tree that bears rich fruit. Indeed, it even benefits unborn children according to this study.

Men who want to have children in the near future should consider hitting the gym.

In a new study led by Kristin Stanford, a physiology and cell biology researcher with The Ohio State University College of Medicine at the Wexner Medical Center, paternal exercise had a significant impact on the metabolic health of offspring well into their adulthood.

Laurie Goodyear of the Joslin Diabetes Center and Harvard Medical School co-led the study, published in the journal Diabetes

“This work is an important step in learning about metabolic disease and prevention at the cellular level,” said Dr. K. Craig Kent, dean of the Ohio State College of Medicine.

Recent studies have linked development of type 2 diabetes and impaired metabolic health to the parents’ poor diet, and there is increasing evidence that fathers play an important role in obesity and metabolic programming of their offspring. Continue reading

Everything you wanted to know about Sugars …

One of the most helpful facts I ever learned about sugars and reading ingredients notices is that there are four grams of sugar in a teaspoon. So, when you read 20 grams of sugar, you can visualize five teaspoons full.

Fries with that? Maybe not …

As an old fan of McDonald’s fries I was disappointed to learn that potatoes aren’t very healthy veggies. Here is what Harvard’s T.H. Chan had to say about them.

If you’re looking for healthful vegetables, steer clear of potatoes, say nutrition experts.

In a November 29, 2018 New York Times article, Harvard T.H. Chan School of Public Health’s Eric Rimm advised limiting consumption of potatoes, which he called “starch bombs.” Potatoes have a high glycemic index, which has been linked with an increased risk of obesity, diabetes, and cardiovascular disease, according to the article.

Rimm, professor of epidemiology and nutrition and director of Harvard Chan School’s Program in Cardiovascular Epidemiology, said that french fries—coated in oil and sometimes served with high-calorie toppings like cheese or chili—are a particularly unhealthful form of potatoes. Referring to fast-food meals that come with fries, he said, “I think it would be nice if your meal came with a side salad and six french fries.”
