A brand new analysis examine has discovered that following a Mediterranean weight loss plan just isn’t linked to a decreased threat of dementia.
Various earlier analysis research have indicated that consuming a nutritious diet could cut back an individual’s threat of dementia. Nevertheless, a brand new examine has discovered that two diets together with the Mediterranean weight loss plan aren’t linked to a decreased threat of dementia. The findings had been revealed within the October 12, 2022, on-line situation of Neurology, the medical journal of the American Academy of Neurology.
The Mediterranean weight loss plan features a excessive consumption of greens, legumes, fruits, fish, and wholesome fat reminiscent of olive oil, and a low consumption of dairy merchandise, meats, and saturated fatty acids. The American Coronary heart Affiliation and American Diabetes Affiliation advocate the Mediterranean weight loss plan as a wholesome dietary sample that will cut back the danger of cardiovascular illnesses and kind 2 diabetes, respectively.
“Earlier research on the results of weight loss plan on dementia threat have had blended outcomes,” stated examine writer Isabelle Glans, MD, of Lund College in Sweden. “Whereas our examine doesn’t rule out a doable affiliation between weight loss plan and dementia, we didn’t discover a hyperlink in our examine, which had a protracted follow-up interval, included youthful members than another research and didn’t require folks to recollect what meals that they had eaten repeatedly years earlier than.”
For the examine, researchers recognized 28,000 folks from Sweden who had been adopted over a 20-year interval. Individuals had a median age of 58 and didn’t have dementia at first of the examine. Throughout the examine, members stuffed out a seven-day meals diary, an in depth meals frequency questionnaire, and accomplished an interview. By the top of the examine, 1,943 folks, or 6.9%, had been recognized with dementia, together with Alzheimer’s disease and vascular dementia.
Researchers examined how closely participants’ diets aligned with conventional dietary recommendations and the Mediterranean diet.
After adjusting for age, gender, and education, scientists did not find an association between following either a conventional diet or the Mediterranean diet and a reduced risk of dementia.
Additional research is needed to confirm the findings, Glans noted.
Nils Peters, MD, of the University of Basel in Switzerland, who wrote an editorial accompanying the study, said, “Diet on its own may not have a strong enough effect on memory and thinking, but is likely one factor among others that influence the course of cognitive function. Dietary strategies will still potentially be needed along with other measures to control risk factors.”
A limitation of the study was the risk of participants misreporting their own dietary and lifestyle habits.
