The past few decades have produced a series of what-to-eat and what-to-avoid diets for weight loss, inflammatory conditions, and other purposes. Shocking to many, however, is a recent Harvard study of how much meat over 130,000 people consumed over four decades affects the risk of developing dementia.
They separated meat consumption into processed and unprocessed meats. The study showed that one serving of processed meat per day (2 slices of bacon or 1 piece of sausage) was associated with a 13 percent increased risk of dementia. They also suggested that replacing one serving of processed meat with fish daily reduced the risk of developing dementia by almost a third.
Even more shocking was their finding that frequent consumption of unprocessed meat (like steak or lamb) conferred a 16 percent increase of cognitive decline, which often leads to dementia. Interestingly, even unprocessed meats can be harmful. The association of the preservatives in processed meat to colon cancer is well-known. And the association of frequent meat consumption leading to hypercholesterolemia can increase the risk of stroke and heart attacks. The suggestion that meat consumption is a risk factor for dementia, however, is a novel concern.
Before you throw out your steak knives, it is important to know that this government-sponsored study has been criticized because it did not consider other lifestyle choices. It is possible that people who consume large amounts of meat do not exercise or make other healthy diet choices. Further study will be needed.
In the meantime, the adage “everything in moderation” may be the best mantra. BeCareLink can help you follow your cognitive function if you suspect you may be experiencing memory issues.
