Prediabetes may be linked to worse brain health

People with prediabetes, whose blood sugar levels are higher than normal, may have an increased risk of cognitive decline and vascular dementia, according to a new study led by University College London (UCL) researchers.

For the study, published in the journal Diabetes, Obesity and Metabolism, researchers analyzed data from the UK Biobank of 500,000 people aged 58 years on average, and found that people with higher than normal blood sugar levels were 42% more likely to experience cognitive decline over an average of four years, and were 54% more likely to develop vascular dementia over an average of eight years (although absolute rates of both cognitive decline and dementia were low).

The associations remained true after other influential factors had been taken into account – including age, deprivation, smoking, BMI and whether or not participants had cardiovascular disease.

Increased blood sugar levels may decrease benefits of aerobic exercise

Every doctor recommends regular aerobic exercise, since greater aerobic fitness is important for achieving better overall health. But Joslin Diabetes Center scientists have discovered that some benefits of aerobic exercise may be dampened by higher-than-normal blood sugar levels, a condition known as hyperglycemia.

These diminished gains are seen in mouse models and humans with chronic hyperglycemia that is in the “prediabetes” range, says Sarah Lessard, PhD, a Joslin assistant investigator in the section of Clinical, Behavioral and Outcomes Research and senior author on a paper in Nature Metabolism that presents the work. The study also showed that this maladaptive trait is independent of obesity and insulin levels in the blood.

Are sugary drink interventions cutting consumption?

I have written repeatedly about the ill effects of soft drinks, both sugary and diet, on our bodies. You can check out my Page – What’s wrong with soft drinks? for chapter and verse. So this item in Medical News Today citing efforts to curb sugary drink consumption caught my eye.

An evaluation of efforts designed to reduce how many sugary drinks we consume shows some success in changing younger people’s habits but warns they cannot be the only way to cut consumption.

Nutritionists at the University of Leeds have carried out the first comprehensive review of interventions to reduce sugary drinks consumption. The team analyzed 40 studies with 16,500 participants across three age groups: children, teenagers and adults.

Their study, published in the Obesity Reviews journal, found that children participating in these programs reduced their sugary drink intake by around 30%, removing nearly 2.5 teaspoons of sugar from a child’s average intake of 16 teaspoons per day.

Interventions aimed at teenagers saw sugary drink consumption reduced by nearly 10%. However, there was almost no measurable change in adults participating in these programs. Continue reading →

Even mildly excessive body iron stores increase the risk of type 2 diabetes – Study

Diabetes was the seventh leading cause of death in the United States in 2010 based on the 69,071 death certificates in which diabetes was listed as the underlying cause of death. In 2010, diabetes was mentioned as a cause of death in a total of 234,051 certificates, according to the latest information from the American Diabetes Association.

In addition, Diabetes may be under-reported as a cause of death. Studies have found that only about 35 percent to 40 percent of people with diabetes who died had diabetes listed anywhere on the death certificate and about 10 percent to 15 percent had it listed as the underlying cause of death.

Even mildly elevated body iron contributes to the prevalence and incidence of type 2 diabetes, according to research from the University of Eastern Finland. Excess body iron accumulation is a known risk factor of Type 2 diabetes in hereditary hemochromatosis, but the results presented by Dr Alex O. Aregbesola in his doctoral thesis show that elevated iron is a risk factor in the general population as well, already at high levels within the normal range.

Men accumulate more iron and are more at risk Continue reading →

Study supports lower cut-off point for defining prediabetes

At the risk of being a wet blanket on Thanksgiving Day, this seems an appropriate topic.

Let’s face it the majority of us are bad eaters. Some 60 percent of us are overweight and half of them outright obese. Additionally, we are seeing adult onset diabetes occurring in teenagers. We need to start eating better and exercising more.

The health risks and mortality associated with prediabetes seem to increase at the lower cut-off point for blood sugar levels recommended by some guidelines, finds a large study published in The BMJ today.

Prediabetes is a “pre-diagnosis” of diabetes — when a person’s blood glucose level is higher than normal, but not high enough to be considered diabetes. If left untreated, prediabetes can develop into type 2 diabetes. An estimated 79 million people in the US and 7 million people in the UK are thought to be affected. Continue reading →
