Fiber in your diet reduces stroke risk
Submitted by Fiona McPherson
on
Analysis of eight studies on diet and stroke published between 1990 and 2012 has found that risk of first-time stroke dropped with every 7g increase in total daily fibre. That amount of fibre is contained in a bowl of wholewheat pasta plus two servings of fruit or vegetables.
Insufficient data is available to say whether soluble or insoluble fibre is better. The studies came from the United States, northern Europe, Australia, and Japan.
How green tea helps fight cognitive decline & dementia
Green tea is thought to have wide-ranging health benefits, especially in the prevention of cardiovascular disease, inflammatory diseases, and diabetes. These are all implicated in the development of age-related cognitive impairment, so it’s no surprise that regular drinking of green tea has been suggested as one way to help protect against age-related cognitive decline and dementia. A new mouse study adds to that evidence by showing how a particular compound in green tea promotes neurogenesis.
Diet affects your chance of cognitive impairment in old age
In a large Mayo Clinic study, self-reported diet was found to be significantly associated with the risk of seniors developing mild cognitive impairment or dementia over a four-year period.
Why HIV-associated dementia occurs & implications for other disorders
HIV-associated dementia occurs in around 30% of untreated HIV-positive patients. Surprisingly, it also is occasionally found in some patients (2-3%) who are being successfully treated for HIV (and show no signs of AIDS).
A new study may have the answer for this mystery, and suggest a solution. Moreover, the answer may have general implications for those experiencing cognitive decline in old age.
Why metabolic syndrome is linked to cognitive decline?
I’ve reported before on the growing evidence that metabolic syndrome in middle and old age is linked to greater risk of cognitive impairment in old age and faster decline. A new study shows at least part of the reason.
Regular cocoa drinking helps those with MCI
Back in 2009, I reported briefly on a large Norwegian study that found that older adults who consumed chocolate, wine, and tea performed significantly better on cognitive tests. The association was assumed to be linked to the flavanols in these products. A new study confirms this finding, and extends it to older adults with mild cognitive impairment.
Exercise reduces Alzheimer's damage in brain
A study designed to compare the relative benefits of exercise and diet control on Alzheimer’s pathology and cognitive performance has revealed that while both are beneficial, exercise is of greater benefit in reducing Alzheimer’s pathology and cognitive impairment.
Type of fat, not amount of fat, linked to cognitive decline in old age
Data from the Women's Health Study, involving 6,183 older women (65+), has found that it isn’t the amount of fat but the type of fat that is associated with cognitive decline. The women were given three cognitive function tests at two-yearly intervals, and filled out very detailed food frequency surveys at the beginning of the study.
High-fructose diet directly impairs brain function
A rat study has shown how a diet high in fructose (from corn syrup, not the natural levels that occur in fruit) impairs brain connections and hurts memory and learning — and how omega-3 fatty acids can reduce the damage.
We know that these unnaturally high levels of fructose can hurt the brain indirectly through their role in diabetes and obesity, but this new study demonstrates that it also damages the brain directly.
Why eating less may keep the brain young
I have reported often on studies pointing to obesity as increasing your risk of developing dementia, and on the smaller evidence that calorie restriction may help fight age-related cognitive decline and dementia (and help you live longer). A new mouse study helps explain why eating less might help the brain.
