Foods that can age the brain faster, says science

We all forget names, lose keys and misplace cell phones. Occasional brain fog is so common and has so many potential triggers (lack of sleep, stress, medication or depression, etc.) that it’s really hard to know if your brain is aging faster than you expected or if your forgetfulness is just a temporary symptom of living a crazy modern life.

One thing you’ll definitely want to remember to help you stay mentally sharp is that your eating habits over time can accelerate memory decline and other markers of declining cognitive function that’s associated with aging. of the brain

We are still learning about the different forms and causes of dementia and the mechanics of the abnormalities that characterize Alzheimer’s disease, but more and more research is suggesting that our diets play a critical role.

“What we eat affects more than our body; it also affects our brain,” he says Uma Naidoo, MDnutritional psychiatrist, trained chef, and director of Nutritional and Lifestyle Psychiatry at Massachusetts General Hospital.

Eating an order of fries won’t fry your brain. It’s the regular consumption of these unhealthy foods overtime that can compromise your brain power just as it can increase your likelihood of experiencing other disorders associated with aging, such as heart disease, diabetes type 2 and cancer.

We review the types of foods that negatively affect our health and the research behind their dangers.


One way food affects cognitive function is through the brain-gut connection. Science suggests that an unbalanced mix of healthy and unhealthy bacteria in our microbiome can influence our brain chemistry, specifically neurochemicals like norepinephrine, serotonin, and dopamine, which affect learning and memory.

A study published in European Heart Journal found that excessive consumption of red meat can increase levels of trimethylamine N-oxide (TMAO), a byproduct of gut bacteria metabolism. High levels of TMAO may be linked to an increased risk of heart attack and stroke.

An unhealthy microbiome is also linked to chronic inflammation, including brain inflammation, which can affect blood flow to the brain. “Also, changes in gut bacteria can increase amyloid deposits, thereby contributing to Alzheimer’s disease,” Dr. Naidoo writes in her book. This is your brain about food.

Fructose is the sugar in healthy fruit, but it’s also found in cane sugar and high fructose corn syrup (HFCS), the cheap liquid sweetener that food manufacturers add to processed foods to improve its flavor and keep us eating. Cane sugar and HFCS are so prevalent in our food supply (sodas, candy, condiments, salad dressings, canned soups, baked goods, bread, and other processed foods) that they can be a significant hazard to the brain for years of overindulgence. .

The US Department of Agriculture says the average American ingests 47 pounds of cane sugar and 35 pounds of HFCS over the course of a year. This is too sweet. Studies in rodents suggest that getting a large dose of fructose could disrupt the ability of brain cells to signal to each other, causing memory loss and disrupting learning. The results suggest that “eating a high-fructose diet long-term alters the brain’s ability to learn and remember information,” said a UCLA researcher. Fernando Gomez-Pinilla, PhDhe said Daily Science.

Keep track of how often you open a box or can throughout the day. It could be an eye opener. A recent study linked getting more than 20% of daily calories from ultra-processed foods with faster cognitive decline, memory and executive functions like juggling multiple tasks at once.

The research determined that men and women who ate the most ultra-processed foods declined 28% faster in memory, attention, verbal fluency and visual/spatial ability and 25% faster in executive function compared to people who they ate the least amount of highly processed foods. foods Highly processed foods include pre-prepared frozen foods, chips and pretzels, ice cream, store-bought bread, cookies, cake mixes, cereal, packaged snacks, and more.

fried foods

Fried foods: French fries, fried chicken, fried jalapeño poppers, deep-fried Oreos, fried okra and their ilk are among the most ultra-processed foods on the planet. They’re also among the most inflammatory foods you can eat, which suggests a possible reason, according to the results of a large study of more than 18,000 people in a southeastern region known as the “stroke belt.” where it is “fried in the south”. the kitchen predominates.

The connection between fried foods and blood vessel inflammation is well established by other studies. This one, published in Journal of Nutrition Sciencesshowed that participants whose diets included the most fried foods scored lower on tests of memory and cognition.
