"This study shows that there are negative brain / cognitive outcomes, in addition to known cardiovascular outcomes, that are associated with a diet that has (a) high fat content," says neurologist Dr. Neelum T Agarwal, who did not participate in the study. Agarwal, a Fellow of the American Academy of Neurology, is co-leader of the Rush Alzheimer's Center in Chicago.
Over 1600 Japanese men and women without dementia were followed for a period of 10 years. At the beginning of the study, a blood test for trans fat levels was performed and their diets analyzed.
The researchers then corrected other factors that could affect the risk of dementia, such as high blood pressure, diabetes, and smoking. They found that people with the two highest levels of trans fat were 52% and 74% more likely to develop dementia than those with the lowest levels.
"The study used trans fat levels in the blood than the more traditionally used diet questionnaires, which increases the scientific validity of the results," said neurologist Dr. Richard Isaacson, director of the Alzheimer's Clinic at Weill Cornell Medicine in New York.
"This study is important because it is based on preliminary evidence that adopting a trans fat diet may increase the risk of Alzheimer's dementia," said Isaacson, who also did not participate in the study. 1
What are Transmissions
Trans fats can naturally occur in small quantities in certain meat and dairy foods, but the largest exposure comes from the human-created version.
Also called trans fatty acids, artificial trans fats are created through an industrialized process , which adds hydrogen to the liquid vegetable oil s to make them firmer (think semi-soft margarine and shortening).
The food industry loves trans fats because they are cheap to produce, last a long time, and give the food great taste and texture.
In addition to fried foods, trans fats are found in coffee cream, cakes, pie crusts , frozen pizza, cookies, cookies, cookies and dozens of other processed foods.
In a Japanese study, researchers found that sweet cakes are the highest contributors to higher levels of trans fat. Next up was the margarine, followed by candy, caramel, croissant, non-dairy cream, ice cream and rice crackers.
US regulatory action
After extensive research, it has revealed the link between trans fat and bad cholesterol (LDL) combined with good cholesterol reduction (HDL), the US Food and Drug Administration 2015
Companies were given three years to stop using them; then the FDA began providing extensions to various parts of the industry. The last extension expires on January 1st.
But even if every manufacturer complies with the first year, that does not mean that the trans fats have disappeared from the shelves of food. According to the FDA, if a portion of food contains less than 0.5 grams, companies can label the food as "0 gram" of trans fat.
Even in small doses, artificial trans fats will still be available to contribute to cardiovascular disease, diabetes and other conditions such as dementia.
