55 million people worldwide are affected by dementia, 1.8 million in Germany alone. According to the German Alzheimer Society, the number will rise to 139 million worldwide by 2050.
Now there are new findings: Our diet can significantly influence the personal risk of Alzheimer’s.
New study from Brazil
The focus is a study from the University of São Paulo in Brazil, which sheds light on the negative long-term consequences of a diet consisting of processed, industrially produced foods. Scientists examined more than 10,000 test subjects over a period of 10 years. They regularly filled out questionnaires about their eating habits, while their mental abilities were tested in various tests.
The food consumed was divided into three categories:
► Low-processed foods (e.g. fresh fruit, vegetables, whole grain products, meat, fish, milk)
► Processed foods (e.g. canned fruit, bread, cheese, salted, smoked or preserved meat and fish products)
► Highly processed foods (e.g. industrially processed foods with many additives)

Highly processed foods increase the risk
The result is alarming: subjects who ate mainly highly processed foods had a 28 percent higher risk. Just 400 calories of highly processed foods per day are enough to significantly increase the risk of Alzheimer’s.
But there is also good news: The study also shows that subjects who consumed 80 percent of their diet with unprocessed foods showed no signs of cognitive or executive decline.
The 80/20 rule could be the key: If 80 percent of the diet consists of nutrient-dense, unprocessed foods, the remaining 20 percent can be flexibly structured.

Other risk factors for Alzheimer’s disease
In addition to diet, other factors also influence the risk of Alzheimer’s disease. The Alzheimer Research Initiative eV lists, among other things, head injuries, excessive alcohol consumption and fine dust exposure as risk factors.
