Obesity holds a significant impact on memory function, as research suggests. The University of Alabama recently created a study to determine the link between being chronically obese and how the memory is impacted. The case study is published in the Journal of Neuroscience this month.
An Ongoing Issue
In many countries, including the United States obesity is an ongoing issue. As each generation passes, more and more individuals are fighting obesity. This one health issue alone holds great negative outcomes for the individuals in many nations.
Memory impairment is one negative outcome for those who suffer from obesity. Scientific studies now show a clear link between the two. It is believed the cause is from an altered expression within the genes in the hippocampus of the brain. In other words, the DNA of the brain changes and can either promote memory, or suppress memory. In the case of individuals with obesity, the DNA changes to promote suppression (loss) of memory.
High Fat Diet
Within the study at the University of Alabama, mice were provided a high fat diet which induced obesity over a period of time. Then, the mice were studied within the context of memory functions. The results show the diet which is high in fat definitely causes changes within the brains’ DNA which has a negative impact on the body.
Development Over Time
Memory loss which is related to obesity develops over time. The more time which passes while consuming a high fat diet with an increasing body weight, the more likely memory loss will develop. In mice, memory loss began at approximately sixteen weeks.
Gene Sert1 Enzyme
During the study, researchers focused time studying the Sert1 gene which makes an enzyme that is actively used in the neurons of the brain. Neurons are responsible for gathering and transmitting signals within the brain. With obesity, it was found the specific enzyme is depleted and if present in small amounts, it was nonfunctional.
Similarly, babies who are born without the Sert1 gene have impaired memory. Their bodies cannot form new neuron synapses which is very important to life within the central nervous system. The synapses allow sensory information to flow properly.
A clear connection exists in obesity and mental decline over time. People who are in their forties who are obese hold a 75% chance of developing dementia. Higher body mass indices in people are also associated with decreased cognitive scoring. A study of over eight thousand twins show those obese at approximately 45 years of age will show signs of dementia later on in life.
Dietary changes are needed within the United States and other countries who are suffering from the increasing obesity statistics. The move toward eating fresh fruits and veggies along with eliminating high fat foods from the diet is absolutely necessary. Eliminating processed foods from the diet is required. Adding superfoods, like Dr. Colbert’s Fermented Green Supremefood, with supporting nutrients and enzymes will also help individuals gain needed substances for healthier living. Taking a more “natural course” of eating, going back to the basics, will produce life and excellent mental clarity.
