Sugar May Harm Brain Health

RATE THIS! +39
Posted in Science on 9th Jul, 2014 01:45 AM by AlexMuller

A poor diet can eat away at brain health. Now a study in Neurology helps elucidate why. It suggests that eating a lot of sugar or other carbohydrates can be hazardous to both brain structure and function. Diabetes, which is characterized by chronically high levels of blood glucose, has been linked to an elevated risk of dementia and also to a smaller hippocampus, a brain region critical for memory.

 

The new study sought to identify whether glucose had an effect on memory even in people without the disease because having it could induce other brain changes that confound the data. In the experiment, researchers at the Charité University Medical Center in Berlin evaluated both short- and long-term glucose markers in 141 healthy, nondiabetic older adults. The participants performed a memory test and underwent imaging to assess the structure of their hippocampus.

 
Higher levels on both glucose measures were associated with worse memory, as well as a smaller hippocampus and compromised hippocampal structure. The researchers also found that the structural changes partially accounted for the statistical link between glucose and memory. According to study co-author Agnes Flöel, a neurologist at Charité, the results “provide further evidence that glucose might directly contribute to hippocampal atrophy,” but she cautions that their data cannot establish a causal relation between sugar and brain health.

When researching any link between diet and health it is important to be very rigorous otherwise people are not going to take it into account. There have been so many contradictory studies and opposite advices for some topics and public has been confused. This study is putting findings in context and calls for more research

These findings indicate that even in the absence of diabetes or glucose intolerance, higher blood sugar may harm the brain and disrupt memory function. Future research will need to characterize how glucose exerts these effects and whether dietary or lifestyle interventions might reverse such pathological changes. Reply

Many believe that future research will find sugar is addictive and that we may need to introduce a sugar tax. Last year doctors called for a soft drinks tax to reduce sugar intake.

Well, people should be encouraged to take more control over their food and start preparing meals that have low sugar and healthy constituents - in this case they would know exactly what they are consuming Reply

Perhaps Governments should not use taxation as proposed recently. I know that this is a complex problem demanding a multi-faceted response. However, taxation should not be the knee-jerk answer. Education must play its part. Reply
