Alzheimer’s Linked To Too Much of This In Your Diet

Alzheimer’s Linked To Too Much of This In Your DietThe researchers studied samples of brain tissue from people with and without Alzheimer’s disease.

Excess sugar in the diet could play an important role in the development of Alzheimer’s disease, new research finds.

Too much glucose (sugar) in the diet damages a vital enzyme which helps fight the early stages of Alzheimer’s disease.

Dr Omar Kassaar, the study’s first author, said:

“Excess sugar is well known to be bad for us when it comes to diabetes and obesity, but this potential link with Alzheimer’s disease is yet another reason that we should be controlling our sugar intake in our diets.”

The researchers studied samples of brain tissue from people with and without Alzheimer’s disease.

They found that sugar can damage an enzyme called MIF (macrophage migration inhibitory factor).

Professor Jean van den Elsen, a study co-author, explained:

“We’ve shown that this enzyme is already modified by glucose in the brains of individuals at the early stages of Alzheimer’s disease.

We are now investigating if we can detect similar changes in blood.

Normally MIF would be part of the immune response to the build-up of abnormal proteins in the brain, and we think that because sugar damage reduces some MIF functions and completely inhibits others that this could be a tipping point that allows Alzheimer’s to develop”.

MIF helps to fight the build up of abnormal proteins in the brain, which are characteristic of Alzheimer’s.

The reduction of MIF activity by glucose could eventually lead to a ‘tipping point’ in Alzheimer’s progression.

Dr Rob Williams, a study co-author, said:

“Knowing this will be vital to developing a chronology of how Alzheimer’s progresses and we hope will help us identify those at risk of Alzheimer’s and lead to new treatments or ways to prevent the disease”.

The study was published in the journal Scientific Reports (Kassaar et al., 2017).

2 Ancient Practices Beat Modern Ones For Preventing Pre-Alzheimer’s Memory Loss

Elderly couple stretchingStudy included over-55ers who had simple memory problems like forgetting names and appointments.

Meditation and yoga are more effective than memory games or crosswords for fighting memory problems linked to Alzheimer’s, new research finds.

Researchers compared two groups of people aged over 55 who reported memory problems like losing things, forgetting names and appointments.

One group were given crosswords and memory training to do over 12 weeks.

The other group did both yoga and meditation for an equivalent amount of time.

Professor Helen Lavretsky, one of the study’s authors, explained the results:


 “Memory training was comparable to yoga with meditation in terms of improving memory, but yoga provided a broader benefit than memory training because it also helped with mood, anxiety and coping skills.”


Both groups did one hour per week of their respective tasks.

Kundalini yoga was the type practiced in classes.

It involves focusing on breathing, chanting as well as the visualisation of light.

At home, people in the yoga group practiced 20 minutes of Kirtan Kriya meditation, which is a part of Kundalini yoga.

This type of yoga and meditation has been used in India for hundreds of years.

The researchers found that memory improvements were similar across both the groups.

However, people who did yoga and meditation had better visuo-spatial memory: the type used for navigating and recalling locations.

Yoga and meditation also had better results in reducing depression and anxiety.

It helped people develop higher levels of resilience and increased their ability to cope.

Brain scans showed significant differences in brain function in the yoga meditation group which were not seen in the others.

Mr Harris Eyre, the study’s first author, said:


“Historically and anecdotally, yoga has been thought to be beneficial in aging well, but this is the scientific demonstration of that benefit.

We’re converting historical wisdom into the high level of evidence required for doctors to recommend therapy to their patients.”


Professor Lavretsky concluded:

“If you or your relatives are trying to improve your memory or offset the risk for developing memory loss or dementia, a regular practice of yoga and meditation could be a simple, safe and low-cost solution to improving your brain fitness.”

The study was published in the Journal of Alzheimer’s Disease (Harris et al., 2016).
