Preliminary research suggests that consuming higher amounts of processed red meat, such as hot dogs, sausages, and bacon, is associated with an increased risk of dementia.
Study participants who consumed 0.25 or more servings of processed meat per day, or roughly two servings per week, had a 15% higher risk of developing dementia compared to those who consumed less than 0.10 servings per day, or about three servings per month.
According to Yuhan Li, MHS, a research assistant at the Channing Division of Network Medicine, Brigham and Women’s Hospital, Boston, “We found that consuming more red meat, especially processed red meat, was linked to a higher risk of dementia and worse cognition.” Li shared these findings with Medscape Medical News.
However, the study also noted that substituting processed red meat with legumes and nuts might help mitigate this elevated risk. The researchers evaluated data from two significant long-term studies: the Nurses’ Health Study and the Health Professionals Follow-Up Study. The Nurses’ Health Study recruited female registered nurses aged 30-55 in 1976, while the Health Professionals Follow-Up Study recruited male health professionals aged 40-75 in 1986.
To assess the association between food intake and dementia, the researchers used validated semi-quantitative food frequency questionnaires to measure the intake of processed red meat every two to four years. Participants were asked how frequently they consumed dishes containing processed red meat.
Li emphasized the findings, stating, “We found that a higher intake of red meat, particularly processed red meat, was associated with a higher risk of developing dementia, as well as worse cognition.” These results underscore the potential health risks of consuming processed red meat and highlight the importance of dietary choices in maintaining cognitive health.
In summary, the research indicates a clear link between higher consumption of processed red meat and an increased risk of dementia. Substituting processed red meat with healthier alternatives such as legumes and nuts may help reduce this risk, promoting better long-term cognitive health.
