Cognitive decline linked to ultra-processed foods, study finds

A new study has identified the type of diet that can cause severe and severe memory loss. The lead author of the study, published in the journal Brain Behavior and Immunity-Linked Diets and Memory Impairment, said rapid memory decline is more likely to progress to neurodegenerative diseases such as Alzheimer’s disease. The researchers hope the findings will help guide dietary choices as people age.

Cognitive decline linked to ultra-processed foods, study finds

Eating ultra-processed foods for more than 20% of your daily calorie intake puts you on a path to cognitive decline, a new study suggests. We all know how to eat ultra-processed foods that make life easier, such as packaged soups. , sauces, frozen pizza and ready meals are not good for health. We also don’t eat all the comfort foods we love so much: hot dogs, sausages, hamburgers, french fries, sodas, cookies, cakes, candy, donuts, and ice cream. risk of obesity, heart and circulatory problems, diabetes and cancer. They even shorten our lives. Now, a new study shows that consuming more ultra-processed foods contributes to overall cognitive decline, including areas of the brain involved in executive function—information processing and decision-making. The study found that people with the most ultra-processed foods had 28% faster global cognitive decline and 25% faster decline in executive function compared to people who consumed the least processed foods. The new research and replication results are very compelling and highlight the important role of nutrition in maintaining and strengthening brain health and reducing the risk of brain diseases as we age,” said Rudy Tanzi, professor of neurology at Harvard Medical School and director of the Division of Genetics and Aging Research at Massachusetts General Hospital in Boston. He was not involved in the research.Tanzi, who wrote about ultra-processed foods in his book “Heal Yourself: A Revolutionary New Plan to Boost Your Immune System and Stay Well for Life,” says the main problem with ultra-processed foods. “They are typically very high in sugar, salt and fat, all of which contribute to systemic inflammation, perhaps the biggest threat to healthy aging of the body and brain.” At the same time, because they are convenient as a fast food, they also replace eating foods rich in plant fiber, which is important for maintaining the health and balance of the trillions of bacteria in your gut microbiome, he added, “which is especially important for brain health and is related to age.” reduces the risk of brain diseases.

The study, presented Monday at the 2022 Alzheimer’s Association International Conference in San Diego, followed more than 10,000 Brazilians for up to 10 years. More than half of the study participants were female, White, or college educated, and the average age was 51. Cognitive testing, immediate and delayed word recall, and verbal fluency were administered at the beginning and end of the study, and participants were asked about their diet.” Brazil, ultra-processed food- “Food accounts for 25 to 30% of total caloric intake.

Dr. Claudia Suemoto, assistant professor of geriatrics at the University Medical School. “Fifty-eight percent of calories consumed by United States citizens, 56.8% of calories consumed by Britons and 48% of calories consumed by Canadians come from ultra-processed foods,” Suemoto said. fats, sugars, starches and protein isolates), they contain little or no whole food and usually contain fragrances, dyes, emulsifiers and other cosmetic additives”. “According to research. Compared to people who ate less than 20% of the food, global cognition declined 28% faster and executive functions declined 25% faster, “said study author Natalia Gonçalves, a researcher at the department of road. Conducted research at the Medical School of the University of São Paulo. 2000 calories per day For a person who eats 20%, that equates to 400 or more calories — for comparison, a small order of McDonald’s fries and a regular cheeseburger has a total of 530 calories. have, and never smoked, were less likely to drink alcohol,” the study found. “People should learn to cook more and prepare their own meals from scratch. I know. We say we don’t have time, but it really doesn’t take that long, Suemoto said. “It’s worth it because you’re protecting your heart and protecting your brain from dementia or Alzheimer’s,” he added. “That’s the take-home message: stop buying super processed stuff.”

Eating ultra-processed foods for more than 20% of your daily calorie intake puts you on the path to cognitive decline, a new study finds.

We all know that eating ultra-processed foods that make life easier, such as packaged soups, sauces, frozen pizzas, and ready-to-eat meals, is not good for our health. We also didn’t eat all the comfort foods we love so much: hot dogs, sausages, hamburgers, fries, sodas, cookies, cakes, candy, donuts, and ice cream.

Studies show that they increase the risk of obesity, heart and circulatory problems, diabetes and cancer. They can shorten our lives.

Now, a new study shows that eating more ultra-processed food can lead to overall cognitive decline, including the parts of the brain involved in executive function – the ability to process information and make decisions.

The study found that men and women who consumed the most ultra-processed foods had 28% faster global cognitive decline and 25% faster decline in executive function, at least compared to those who consumed the most processed foods.

“Although further study and replication is required, the new results are very convincing and highlight the important role of nutrition in maintaining and strengthening brain health as we age and reducing the risk of brain diseases as we age,” said neurology professor Rudy Tanzi.

At the beginning and end of the study, cognitive testing including immediate and delayed word recall, word recognition, and verbal fluency was administered, and participants were asked about their diet.

“In Brazil, ultra-processed foods make up 25 to 30% of total calories. We have McDonald’s, Burger King, and we eat a lot of chocolate and white bread. Unfortunately, it’s not much different from many other Western countries,” said one of the authors, Dr. . Claudia Suemoto, Assistant Professor, Department of Geriatrics, Medical School, University of São Paulo.

“58% of calories consumed by citizens of the United States, 56.8% of calories consumed by Britons and 48% of calories consumed by Canadians come from ultra-processed foods,” Suemoto said.

Ultra-processed foods are defined as “industrial formulations that contain little or no nutrients (fats, oils, sugars, starches, and protein isolates) and typically contain flavorings, colorings, emulsifiers, and other cosmetic additives.” to read.

“People who ate more than 20% of their daily calories from processed foods had a 28% decline in global cognition and 25% faster decline in executive function compared to people who ate less than 20%,” said study author Natalia Gonsalves. Research Fellow, Department of Pathology, Medical School, University of São Paulo.

For someone eating 2,000 calories a day, 20% equals 400 or more calories — by comparison, a small order of fries and a regular cheeseburger at McDonald’s has a total of 530 calories.

Those with the most ultra-processed foods were also “younger, female, white, with higher education and income, and never smoked, with lower alcohol consumption,” the study found. The study found.

“People need to know that they have to cook more and make their own food from scratch. I know. We say we don’t have time, but it really doesn’t take that much time,” Suemoto said.

“And it’s worth it because you protect your heart and protect your brain from dementia or Alzheimer’s,” he added. “That’s the take-home message: stop buying super processed stuff.”
