What can unhealthy eating lead to?

If the hippocampus is damaged, however, the memories of the tastiest (but mostly unhealthy) foods are so vivid that you can occasionally think of nothing more than how to best and quickly get to these foods.

Eating unhealthy foods increases the chances of developing dementia

Damage or shrinkage of the hippocampus is also a risk factor for dementia and Alzheimer's disease, because with a disturbed hippocampus less and less information can get from short-term to long-term memory.

At first you don't feel these changes in the brain very clearly. In older age, however, they can no longer be hidden and there are clear changes in behavior that indicate the corresponding brain damage.

Eating unhealthy foods causes brains to shrink

In September 2015, further research results on this topic were published and published in an international specialist journal BMC Medicine released. Researcher of the Deakin University and the Australian National University (ANU) were also able to show how diet affected certain areas of the brain (including the hippocampus).

With the help of magnetic resonance tomography, the size of the hippocampus was measured in the study participants (between 60 and 64 years of age). Those people who ate unhealthily, liked to consume sweetened beverages and salty snacks as well as processed meat products had a smaller hippocampus in this study than the participants who preferred foods rich in vital substances, such as vegetables, fruits and fish. Other factors that can affect the size and function of the hippocampus (e.g. smoking, depression, too little exercise, etc.) were taken into account.

Healthy eating is critical to a healthy brain

Professor Felice Jacka, head of the study, explains that unhealthy food no longer just settles on the hips, but clearly also damages the brain. "It is becoming more and more apparent that diet is very important - for both physical and mental health. Other research recently found that diet was a major risk factor for depression, anxiety, and dementia - but we didn't know exactly how exactly the diet affects the brain, which has now been clarified. "

A healthy diet is therefore a simple method with which one can improve mental health, increase brain performance by hand and prevent dementia - of course only if there is still a certain amount of self-control.
