Beijing: Scientists have found a link between excessive consumption of vitamin B1 and increased risks of dementia in a study published in the Journal of General Psychiatry.
The Link Between Vitamin B1 and Cognitive Decline
Vitamin B1, also known as thiamine, is naturally found in grains, fruits, liver, and salmon, and not consuming it in the required amount is associated with health issues.
According to the research, the daily required amount of thiamine is 0.68 milligrams. A 170-gram piece of salmon contains approximately 0.6-0.7 milligrams of thiamine, while a 30-gram serving of cereal contains roughly 1.2 milligrams of thiamine.
Researchers suggested that a thiamine deficiency could potentially lead to inadequate transmission of energy to neurons in the brain, thereby affecting cognitive function. This study sheds light on the importance of maintaining thiamine consumption to prevent cognitive issues in older individuals.
The study analyzed data obtained from the China Health and Nutrition Survey. This data included information from 3100 individuals who reported their dietary habits from 1989 to 2011 and underwent cognitive function tests four times from 1997 to 2006.
The average age of the participants in the study was 63 years, and they were tested by recalling words and facing number pattern challenges.
