Trans fat may up dementia risk 反式脂肪可能增加痴獃風險

Trans fat may up dementia risk

Trans fatty acids, or trans fat are used or formed in processed foods and restaurant-served foods. They have been correlated to high risk of heart disease, stroke and heart attack in previous studies. In the United States alone, tran fat is linked to 100,000 heart disease associated deaths.

Now a new study led by researchers from Nakamura-Gakuen University suggests that trans fat may increase risk of dementia, or speed up loss of cognitive functions.

The Japanese study published in the journal Neurology finds older adults who have high serum levels of trans fat are at 52 to 74 percent increased risk of developing dementia.

Trans fat can be present in a processed food or restaurant-served food even though the nutrition label says zero trans fat. The U.S. Food and Drug Administration allows food processors to label a food zero trans fat when the food contains less than 0.5 grams of trans fat per serving. Also natural vegetable oils can be transformed to become trans fat after the food is thermally processed.

反式脂肪可能增加痴獃風險

反式脂肪酸或反式脂肪是加工食品和餐廳供應食品中的不健康物質。在以前的研究中，它們與心臟病、中風和心臟病的高風險有關。僅在美國，轉脂肪就與10萬例心臟病相關死亡有關。

現在，由中村大學研究人員領導的一項新研究表明，反式脂肪可能會增加痴呆症的風險，或加速認知功能的喪失。

發表在《神經病學》雜誌上的日本研究發現，血清中反式脂肪含量高的老年人患癡呆症的風險增加52%至74%。

反式脂肪可以存在於加工食品或餐廳提供的食物中，即使營養標籤上寫著零反式脂肪。 美國食品和藥物管理局允許食品加工商在食品每份含有少於0.5克時，對零反式脂肪食品進行標籤。 此外，天然植物油可以在食物經過熱處理后轉化為反式脂肪。
