We had recently done a post on Dementia, early signs and symptoms in detail You can read it here… Here we are going to discuss two primary sources of trans fats in the human diet that are natural and artificial and are supposedly linked with Dementia.
Natural and Artificial fats
Natural fats can be found in dairy products and meat of some animals.
Artificial fats are the products of industrial process that adds hydrogen to vegetable oil to make it solid. Consuming trans fats increases the risk of heart diseases and risk of type 2 diabetes.
A research study on 1628 people of 60 years of age, who were not suffering from dementia, was conducted. After keenly observing them for 10 years, it was found that 377 of them got diagnosed with dementia. The participants in this large group were divided into four equal smaller groups according to their blood levels of trans fat.
The participants with the highest blood level of trans fat had incidence rate of 29.8 per 1000 persons. The next highest group had an incidence rate of 27.6 per 1000 persons, and the lowest group had 21.3 per 1000 persons.
The researchers of the study adjusted the results for other factors like smoking conditions that influence the risk of dementia. After making adjustment in the study, it was found that people with the highest blood trans fat has 52% higher chance of developing Dementia.
Why trans fats are banned in The United States!
The FDA in the US banned artificial fats in 2018, and that only according to them is supposedly going to reduce thousands of heart attacks and deaths on a regular basis. However, there is a provision for foods containing less than 0.5g of trans fat.
Sweets and Pastries are maximum Trans Fat
These are the strongest contributors, followed by margarine, sugar confectionery (like candies, caramels, and chewing gum) and croissants.
The WHO has proposed a step by step guide to remove trans fat from the food chain. It is estimated that consumption of trans fats causes above 500,000 deaths due to cardiovascular diseases. Increased levels of elaidic acid, which is a major trans fatty acid which is formed when vegetable oils are partially hydrogenated, were prominently associated with higher risk of developing dementia as well as Alzheimer’s disease over a follow-up period of 10-years. These were the conclusions made after accounting for hypertension, diabetes, and other risk factors, according to Toshiharu Ninomiya, MD, PhD, of Kyushu University in Fukuoka, and other co-authors of the study.
The research findings also raised the possibility that if intake of foods high in trans fat is avoided, it might reduce the risk of future onset of dementia.
There is still a lot of research work going on looking for the link between nutrition and dementia but still a lot is unknown and no confirmed conclusion can be decided upon. According to Ninomiya added, “Further investigation is needed to clarify the potential role of nutrition in the development of dementia.”
Do you think there is any link between trans fats and dementia?
