Obesity Gene May Be Associated With Dementia

A gene linked to obesity may also be associated with dementia according to research published in the Proceedings of the National Academy of Sciences.

Researchers at the University of California, Los Angeles generated 3D maps of over 200 healthy elderly people’s brains and found a pattern of diminished brain volume in people with specific DNA sequence within the fat mass and obesity-associated (FTO) gene.

‘We’ve known for some time that there’s a link between obesity in mid life and the development of Alzheimer’s disease. However this study suggests that healthy people who carry a specific DNA sequence associated with obesity could be at a greater risk of developing dementia. A reduction in people’s brain tissue was observed but this wasn’t linked to other obesity-related factors such as cholesterol levels, diabetes or high blood pressure. Read more

Too Much Salt, Not Enough Exercise

New research has revealed that an alarming number of British people are not following official advice to reduce their salt consumption and take regular exercise in order to reduce their risk of suffering from serious health conditions such as stroke.

The new survey*, conducted for Siemens in conjunction with The Stroke Association to launch the annual Stroke for Stroke campaign, found that less than half of those questioned (43%) believe they adhere to the GDA (Guideline daily amount) for salt of 6g per day. Also the vast majority (85%) of those questioned failed to take the government recommended 30 minutes of exercise five days a week. This lack of regular exercise, combined with a high salt intake, could lead to high blood pressure and an increased risk of stroke.

The research revealed a general lack of awareness about overall salt consumption and the level of salt found in foods. While 92% of those surveyed believe that too much salt is bad for their health, 40% were unable to correctly identify six grams or one teaspoon as the maximum recommended daily salt allowance for an adult and, worryingly, 64% of those questioned are not concerned about their salt intake.
