Belly Fat? Dementia In Your Future

SHIRLEY S. WANG writes:

People who have more belly fat during middle age, even those considered to be of normal weight, have higher rates of dementia when they reach old age, according to a study in the journal Neurology. The link highlights a body of work showing that health is affected by not just overall body weight but how the weight is distributed.

Too much abdominal fat, which extends into the body cavity around major organs, is known to be a risk factor for cardiovascular disease and diabetes. These new findings, published Wednesday, show that large amounts of belly fat are associated with declining cognitive function as well.

"There is something very potent about collecting fat in your belly," said Rachel Whitmer, lead study author and a scientist at the research division of Kaiser Permanente in Oakland, Calif.

Belly Fat? Dementia May Be In Your Future

Previous research has shown that having an apple-shaped body increases the risk of diabetes, stroke and heart disease, but this is the first time it has been linked to dementia and Alzheimer’s.

In the study, which was published Wednesday by the journal Neurology, people who were both obese and had a large belly were three times more likely to be diagnosed with dementia in later years than those of normal weight and belly size. The risk of dementia nearly doubled in those who were a healthy weight but still had a bulging waist, suggesting that fat accumulated around the midline is particularly unhealthy for the brain.

Whole Grains Aid Sleek Belly And Make For Healthy Heart

In a study of obese adults at risk of heart disease, researchers found that those who trimmed calories and increased their whole-grain intake shed more belly fat and lowered their blood levels of C- reactive protein or CRP.

CRP is a marker of chronic, low-level inflammation in the blood vessels, and both abdominal fat and CRP, in excess, are linked to heart attack and stroke.

In contrast, dieters in the study who mainly ate refined grains, like white bread, were able to lose weight, but they trimmed less fat from the middle and showed no change in CRP.

The findings offer yet more incentive for Americans to opt for whole grains over highly processed versions, according to the researchers.
