Fatty acids are the simplest kind of lipids and can be divided into saturated fatty acids and unsaturated fatty acids according to their molecular structure.
Among them, unsaturated fatty acids are called trans fatty acids if they contain trans-non-conjugated double bond structures.
Dementia is a big family, including vascular, all-cause and mixed dementias, in addition to alzheimer's disease, which is best known.
Starting in 2002, Japanese researchers of 1628 Japanese community residents aged 60 and above without dementia, has launched a 10-year follow-up study, the researchers measured participants trans fatty acids in serum levels, and USES the model to evaluate the crowd for dementia, alzheimer's disease and vascular dementia risk ratio. 纽约时报中英文网 http://www.qqenglish.com
The researchers found that serum levels of trans fatty acids were associated with all-cause dementia and alzheimer's disease in all three types of dementia, but not significantly with the risk of vascular dementia.
A total of 377 participants developed specific types of dementia during follow-up, including 247 alzheimer's patients and 102 vascular dementia patients.
When researchers after adjustment for traditional risk factors for alzheimer's, the body level and higher serum levels of trans fatty acids and the risk for all-cause dementia alzheimer's disease significantly associated with an increased risk, when adjusting the dietary factors, such as total caloric intake, saturated and unsaturated fatty acids in the diet, the relevance is still very significant.
The researchers concluded that higher levels of trans fatty acids in the serum may be a risk factor for all-cause dementia and alzheimer's disease.
In fact, the link between trans fatty acids and dementia has long been a concern of researchers.
As early as the 1990s, researchers found that those who had poor eating habits as teenagers had an increased risk of developing alzheimer's disease in old age, sciencedaily learned.
In a previous study, researchers followed 2,560 people over the age of 65 living in a Chicago suburb and found that those with high levels of trans fatty acids in the elderly experienced faster cognitive decline.
