Reduce your risk of dementia by cutting out this type of meat

Have you ever wondered about the science behind your breakfast sausage or that slice of bacon you relish with your morning coffee? Did you ever imagine that what’s on your breakfast plate could potentially wield an influence over your brain health? Well, new research suggests that eating processed red meat increases dementia risk by 14 percent.

Red meat and dementia

It’s not an alien concept that our diet has implications for our health. But can switching your bacon and sausages for alternatives like nuts, beans, or tofu help decrease your risk of dementia? An intriguing study proposes this very hypothesis. 

This research, conducted by Yuhan Li, a diligent research assistant at the renowned Brigham and Women’s Hospital in Boston, Massachusetts, scrutinizes the impact of processed red meat on our neurological health.

Impact of processed red meat

Li began research to study how eating processed red meat affects the risk of developing dementia.

The study reached out to over 130,000 health professionals from all over the United States, gathering their insights and experiences. Individual health and dietary habits were tracked and analyzed over an impressive 43 years, providing valuable perspectives on wellness.

This longitudinal study involved participants filling out questionnaires every few years. They shared details about their dietary habits. A key focus was their consumption of processed red meat. This included items like bacon, hot dogs, sausages, and salami.

Could we go nuts over meat?

Out of all the participants, over 11,000 cases of dementia surfaced during the study’s follow-up period. The results indicated that consuming two servings of processed red meat saw a 14% hike in dementia risk compared to eating about three servings each month.

The study suggests that by replacing one daily serving of processed red meat with a serving of nuts, beans, or tofu, we could potentially trim the risk of dementia by as much as 20 percent.

Dementia risk from red meat

Li’s research also threw light on cognitive abilities. Over 17,000 participants underwent assessments gauging their language, executive function, and processing prowess. These assessments also evaluated their verbal memory – basically, their ability to recall and understand words and sentences.

The outcomes were eye-opening. Those who made the switch from processed red meat to a serving of nuts, beans, or tofu were found to have sharper memory and thinking skills. In contrast, those who consumed more processed red meat exhibited poorer cognitive skills and a higher risk of dementia.

Unraveling the red meat-dementia riddle

These findings, while compelling, raise an important question – does processed red meat directly contribute to dementia, or is it a lifestyle question? Could it be that those who steer clear of such meat tend to have healthier habits in general?

“Research into diet and the risk of dementia is a major focus. In particular, the effect of eating processed red meat on our health has been a hot topic,” said Dr Richard Oakley, associate director of research and innovation at Alzheimer’s Society.

“In this study more people who ate processed red meat went on to develop dementia and had worse memory and thinking skills.

“It’s important to remember that this doesn’t mean that eating processed red meat is directly related to developing dementia. It may be that people who avoid processed red meat are generally more health conscious and avoid other unhealthy habits that increase dementia risk.

“The diseases that cause dementia are very complex, and it is unlikely that one food group would make a significant difference. Instead, we know that what is good for the heart is good for the head, and recommend everyone to eat a healthy balanced diet.”

Looking ahead

While the study spanned an extensive 43 years, it’s not without its limitations. Researchers only evaluated diet every two to four years. Considering the significant time gap, diets could have swerved substantially in between assessments, potentially tilting the findings.

This concern is echoed by experts like Dr Hilda Mulrooney, reader in nutrition and health at the London Metropolitan University, and Dr Sebastian Walsh, a doctoral fellow at the University of Cambridge. 

They underline the need to understand other factors that were considered while evaluating this apparent red meat-dementia relationship. Their input could paint us a more holistic picture.

Is it time to rethink our eating habits? Possibly. As the adage goes, a journey of a thousand miles begins with a single step. Each small stride towards improved lifestyle choices is a win for mental health. So, let’s take a moment to reflect – what’s on your plate today?
