The latest study raises concerns about foods like hot dogs and their effect on the brain.
—are linked to a host of health ills. Now, the latest study finds that eating too much red meat may even harm the brain., Dr. Daniel Wang, an assistant professor of medicine at the Brigham and Women’s Hospital and Harvard Medical School, and his team report that people who eat more processed red meat had a 14% higher risk of developing dementia over more than four decades that those who consumed minimal amounts.
“Based on this data, we see that if people have higher processed red meat intake, they have a higher risk of dementia, a higher risk of subjective cognitive decline, and worse cognitive function,” says Wang. It didn't take much meat to reach that upper limit. The 14% higher risk of dementia was linked to people who ate at least a quarter of a single 3-oz. serving of processed red meat daily—equivalent to two slices of bacon, one and a half slices of bologna, or a hot dog—compared to those who ate less than a tenth of a serving a day.Wang plans to keep studying these populations to better understand how processed red meat affects the brain, and possibly dementia.
However, on the scale that measured people’s own assessments of their cognitive function, those who ate unprocessed red meat had a 16% higher risk of having memory issues than those who ate minimal amounts. This subjective assessment included six to seven yes-or-no questions, including whether they had more difficulty remembering the names of close friends in the past year compared to the previous year, or whether they had problems finding their way home in the past year.
