If You Have This in Your Mouth, You May Have Alzheimer’s — Eat This Not That

By Ghuman


Alzheimer’s disease is a devastating condition that affects millions of people around the world. It is a progressive neurological disorder that causes memory loss, confusion, and difficulty with everyday tasks. While there is no cure for Alzheimer’s, there are certain lifestyle changes that can help reduce the risk of developing the disease. One of the most important changes is to watch what you eat. Certain foods have been linked to an increased risk of Alzheimer’s, while others may help protect against it. In this article, we will discuss the foods that you should eat and avoid if you want to reduce your risk of developing Alzheimer’s. We will also discuss the potential benefits of certain foods and how they may help protect against Alzheimer’s.

If You Have This in Your Mouth, You May Have Alzheimer’s — Eat This Not That

Alzheimer’s disease is a devastating condition that affects millions of people around the world. Unfortunately, there is no cure for the disease, but there are ways to reduce the risk of developing it. One of the most important things you can do is to watch what you eat.

Recent research has found that people who consume a lot of trans fats may be at an increased risk of developing Alzheimer’s. Trans fats are found in many processed foods, such as margarine, fried foods, and baked goods. They are also found in some animal products, such as beef, pork, and dairy products.

The best way to reduce your risk of developing Alzheimer’s is to avoid trans fats as much as possible. Instead, opt for healthier fats, such as olive oil, avocados, and nuts. Eating a balanced diet that includes plenty of fruits, vegetables, and whole grains is also important.

If you are concerned about your risk of developing Alzheimer’s, talk to your doctor. They can help you make lifestyle changes that may reduce your risk. Eating a healthy diet is just one of the many steps you can take to reduce your risk.

Is there a connection between poor oral health and dementia? A new study from Tufts University School of Dental Medicine shows specific mouth bacteria can lead to Alzheimer’s disease and neurodegeneration. Here’s what researchers discovered.

Researchers at Tufts discovered that a specific bacteria in the mouth connected to gum disease can cause an inflammatory response in the brain. “In this study, our lab is the first to find that Fusobacterium nucleatum can generate systemic inflammation and even infiltrate nervous system tissues and exacerbate the signs and symptoms of Alzheimer’s disease,” says Jake Jinkun Chen, Professor of Periodontology and Director of the Division of Oral Biology at Tufts University School of Dental Medicine. “Our studies show that F. nucleatum can reduce the memory and thinking skills in mice through certain signal pathways. This is a warning sign to researchers and clinicians alike. Testing for bacterial load and degree of symptoms could one day become a way to measure the effects of F. nucleatum and manage treatment to slow progression of both periodontal disease and Alzheimer’s.”

The Tufts study is just the latest in several studies linking harmful bacteria with amyloid beta—a key biomarker for Alzheimer’s disease. “To our knowledge, this is the first study showing an association between the imbalanced bacterial community found under the gumline and a CSF biomarker of Alzheimer’s disease in cognitively normal older adults,” says Angela Kamer, DDS, PhD, associate professor of periodontology and implant dentistry at NYU College of Dentistry and the study’s lead author. “The mouth is home to both harmful bacteria that promote inflammation and healthy, protective bacteria.  We found that having evidence for brain amyloid was associated with increased harmful and decreased beneficial bacteria.”

“To remove biofilms and plaque, and prevent tartar formation, you must clean all surfaces of the teeth and gums,” says Andrew J. Corsaro, DMD, MS, clinical assistant professor, College of Dentistry, University of Florida. “That means brushing teeth for two minutes, twice a day, using a soft-bristled toothbrush with a fluoride-containing toothpaste. You must also clean the spaces in-between teeth once a day, typically with dental floss.”


Your diet can impact mouth bacteria, experts warn. “Limit sugar intake, along with other carbohydrate-containing foods and drinks, such as sodas, fruit juices, sweetened coffee and tea, and candy,” says Dr. Corsaro. “You don’t have to completely avoid their consumption, of course, but cutting back on both can be extremely beneficial. Avoid hard and sticky foods that can break teeth and dental work.”

Studies show mouth bacteria can even impact recovery from COVID-19—people with gum disease had a higher risk of hospitalization and other complications. “Looking at the conclusions of our study we can highlight the importance of good oral health in the prevention and management of COVID-19 complications,” explains Belinda Nicolau, contributing author and Full Professor in the Faculty of Dentistry at McGill University. “There is a very strong correlation between periodontitis and disease outcome.” And to protect your life and the lives of others, don’t visit any of these 35 Places You’re Most Likely to Catch COVID.
