Stay off the sweet stuff: Fizzy drinks contain high amounts of fructose which slows the brain
Too much sugar could be making you stupid, according to researchers.
The suggestion follows tests in the laboratory comparing high-fructose corn syrup, which is six times sweeter than cane sugar and a common ingredient in processed foods, with omega-3 fatty acids, known to aid memory and learning.
In an experiment on rats, one group had a sugary diet for six weeks and another was fed healthily.
At the start of the study, published in the Journal of Physiology, the University of California team tested how well the rats navigated a maze – placing landmarks to help them learn the way.
Six weeks later, the researchers tested the rats’ ability to recall the route.
Study co-author Professor Fernando Gomez-Pinilla said the rats fed just a sugary diet were slower and their brains had declined.
He said: ‘Eating a high-fructose diet over the long term alters your brain’s ability to learn and remember information.
However, the good news is that eating nuts and fish such as salmon can counteract this disruption.
‘Our findings illustrate that what you eat affects how you think,’ said Prof Gomez-Pinilla. ‘Adding omega-3 fatty acids to your meals can help minimise the damage.’
While earlier research has revealed how fructose harms the body through its role in diabetes, obesity and fatty liver, this study is the first to uncover how the sweetener influences the brain.
The researchers were studying the impact of high-fructose corn syrup on rats, who have similar brain chemistry to humans.
The inexpensive liquid is six times sweeter than cane sugar and is commonly added to processed foods such as soft drinks.
Professor Gomez-Pinilla recommends yoghurt with fruit rather than processed desserts
‘We’re not talking about naturally occurring fructose in fruits, which also contain important antioxidants,’ said Prof Gomez-Pinilla.
‘We’re concerned about high-fructose corn syrup that is added to manufactured food products as a sweetener and preservative.’
Prof Gomez-Pinilla and co-author Rahul Agrawal found the brain’s of the rats that each consumed a fructose solution as drinking water for six weeks had changed.
Prof Gomez-Pinilla said: ‘Their brain cells had trouble signaling each other, disrupting the rats’ ability to think clearly and recall the route they’d learned six weeks earlier.’
A closer look at the rats’ brain tissue suggested that insulin had lost much of its power to influence the brain cells.
The authors suspect that eating too much fructose could block insulin’s ability to regulate how cells use and store sugar for the energy required for processing thoughts and emotions.
However, their study also suggests that eating foods rich in omega-3 regularly could protect the brain from the effects of fructose.
Prof Gomez-Pinilla said: ‘It’s like saving money in the bank. You want to build a reserve for your brain to tap when it requires extra fuel to fight off future diseases.’

Another helping of garbage from the professors.Im 69,had a high sugar diet all my life,and I am far from stupid.Why do people believe all this nonsense?.

Fat and Carbs have both been vilified as an enemy but in reality it is the consumption of excessive calories that make someone fatter. As someone has kindly pointed out carbs are mealy converted into glucose for energy or stored as glycogen for use in muscles.. 1.31 to 1 ratio of carbs to protein for normal function. Personally I’d rather drink sugar drink than artificial sweeter.

It’s rubbish, the brain is fuelled on glucose(blood sugar) the body converts all carbs to glucose.

Don’t drink soda….Just eat a bag of sugar …It’s cheaper …….!

The brain requires glucose, so, no. If anything, sugar makes you clever.

High Fructose Corn Syrup is NOT the same as Fructose. Fructose is natural. High Fructose Corn Syrup (HFCS or corn sugar) is totally artificial and is made with and contains mercury as part of the production process. The source material is genetically modified (GM) corn that is also toxic as shown in lab studies and further information on this can be found on the internet.

Another reference to diabetes with obesity…. Type 1 Diabetes is a naturally occurring autoimmune disorder where the pancreas stops producing insulin and Type 2 is due to bad diet and unhealthy lifestyle where the insulin produced by the pancreas has little effect or enough isn’t produced – similar names but totally different illnesses.
