It’s a disappointing day for fans of bacon (like me). A recent study published in the medical journal Neurology has revealed that individuals who regularly consume bacon along with other processed red meats such as hot dogs and sausages could face a higher risk of developing dementia and experiencing a decline in cognitive abilities later in life compared to those who avoid these foods. Lead author of the study, Daniel Wang, MD, ScD, points out that while dietary recommendations often focus on reducing the risk of conditions like heart disease and diabetes, the impact of diet on cognitive health is frequently overlooked, despite its association with these diseases. This study emphasizes the significant link between diet and brain health.
Over a span of more than 40 years, researchers tracked the health and lifestyle habits of nearly 134,000 individuals, commencing at an average age of 49. The findings highlighted that those who consumed a daily average of at least a quarter of a 3 oz. serving of processed red meats — equivalent to one hot dog, two slices of bacon, or 1.5 slices of bologna, for instance — were 13% more likely to develop dementia compared to those with lower consumption levels. Furthermore, individuals who consumed higher amounts of processed meats displayed accelerated cognitive decline compared to their peers who consumed less processed meat.
While this news may be disheartening for bacon enthusiasts, those who enjoy unprocessed red meat can find some relief in the fact that it was not significantly associated with dementia risk. However, individuals who consumed unprocessed red meat did have a 16% higher likelihood of experiencing subjective cognitive decline, which includes self-reported memory problems, than those who consumed minimal amounts.
Although bacon has never been hailed for its health benefits, it comes as no surprise that there are potential drawbacks to indulging in this crispy delight. Dr. Joel Salinas, chief medical officer of Isaac Health, suggests that the preservatives and additives present in processed meats, rather than the red meat itself, may pose a greater concern. These additives, such as nitrates, sodium, and unhealthy fats, can lead to negative effects on the gut microbiome by promoting inflammation and decreasing beneficial bacteria, which could contribute to cognitive decline, according to registered dietitian Naria Le Mire, MPH, RD.
Dr. Salinas explains that the high levels of nitrites, nitrates, and sodium found in processed meats can trigger inflammation and oxidative stress in the brain, both of which are linked to neurodegenerative diseases like dementia and Alzheimer’s. Additionally, these meats can impact cholesterol levels, metabolism, insulin resistance, and vascular health, all of which are factors in cognitive decline.
It’s important to remember that brain health is influenced by a variety of factors beyond just diet, as noted by integrative licensed nutritionist Lea Wetzell, MS, LN, CNS. “Brain health is affected by diverse elements like genetics and lifestyle, not just
You can reduce your risk of dementia by 20% or more simply by swapping out that side of bacon for healthier protein options such as legumes, nuts, or fish.
