Mediterranean and 3 Other Diet Types May Lower Dementia Risk, Specially In Women

This Study Examined Dietia Risk While Also Considering The Impact On People With Certain Characteristics, Such As Obesity Or Older Age.

Researchers Evaluated participants’ Dietts Based on Several Scoring Indices. One Looked at adherence to the Mediterranean Diet, and Another at adherence to the Mediterranean-Dash Intervention for Neurodegenerative Delay (Mind) diet. The Mind Diet Combines The Dash and Mediterranean Diets and Focuses on Components Like Nuts, Leafy Vegetables, and Berries.

Next was the recommended food score, which Helps Evaluate Diet Quality Based On How Much People Eat Certain Foods Like Lean Meat, Low-Fat Dairy, Fruits, and Vegetables. There was Also The Alternative Healthy Eating Index-2010, Which Looks at Howl Subone Is Following American Dietary Guidelines.

Finally, Refracchers Also used the energy-adjusted dietary inflammatory index (edii) to look at how inflamatory dietts were. This Index Considers Components Like Sub Vitamins and Minerals and Components Like Alcohol and Fat INTAKE. Refecchers Then Divided Dietary Index Scores into Four Groups. They Also Consido Covariates, Including Physical Activity, Smoking, and Body Mass Index.

Researchers Were Uble to Analyze Data from 131,209 Participants, Who Did Not All Have a Baseline Dementia Diagnosis. They The Had Exact Matching in Each of The Five Dietary Categories for Sex and Age. Exact matching is a Strategy used in cohort studies that can help with confounding.

AT Baseline, The Average Age of Participants Was Age 56. The Average Folow-Up Time Was 13.5 Years, and Threat The Follow-Up, 1,453 Participants Developed Dementia.

Overall, participants with the Lowest Scores for the Mediterranean Diet, The Mind Diet, and the recommended food score experienced

Refrachers Also Observed That Those with the Lowest Inflamatory Diet Scores and the Highest Alternative Healthy Eating Index Scores Had “The Lowest Incident of Dementia after the follow-up period.” However, for these two Groups, there were no quartile group differences that rear rear to significant level.

Researchers Observed that Higher Scores for the Mediterranean Diet, The Mind Diet, The Recommended Food Score, and The Alternative Healthy Eating Index Were All Linked to DecoSedia Dementia Risk. Following More of an inflammatory diet was Linked to an increased Dementia Risk. They Also Found That Higher Scores for the Mind Diet, The Recommended Food Score, and the Alternative Healthy Eating Index Were All Linked to A Deciested Risk for Mild Cognitive Impairment.

Time was also an important factor. For Example, at The Less Than Five-Year Follow-Up, Only The Mind Appeared to Be Associated With A Decuesed Dementia Risk. AT THE FIVE TO TEN-YEAR FOLLOW-UP, MORE CLOSELY FOLLOWING THE MIND DIET, THE RECOMMENDED FOOD SCORE, AND THE ALTERNATIVE HEALTHY EATING INDEX APPEARED TO DECREASE DEMINIA RISK.

At the Ten-Year or More Mark, Sub Associations Remaled Signan, Such as How Greater Following of the Mediterranean Diet Appeared To Lower Dementia Risk by 24%.

Subgroup Analysis Looked at sex, Age, and Obesity. Researchers Found that for participants Ages 60 and Older, More Closely Following The Mediterranean Diet and the Alternative Healthy Eating Index Reduced Dementia Risk, But This was the case for young participants. The Associations with Other Scoring Indexes Were Still Significant Hardless of Age.

For Women, Closer Adherence to All Healthy Diets and Lower Inflamatory Diet Scores All Appeared To Lower Dementia Risk. For Men, Only The Recommended Food Score Appeared to Signantly Decree Dementia Risk, and The Effects Were Still Better for Women.

Following The Mediterranean Diet Appeared To Help with Dementia Risk Regardless of Weight. A Greater Inflammatory Diet Score was Associated with an Increased Risk for Dementia in Participants With Obesity. The Other Healthy Dietary Patterns Besides The Mediterranean Diet Helped Lower Dementia Risk for Participants Who Did Not Have Obesity.

Finally, Researchers Looked at How these Diets Impacted People With the Apoeε4 Genotype, which can Risk increase For Alzheimer’s Disease. For Non-Apoeε4 Carriers, Higher Scores of All Healthy Diets Helped to Decue Dementia Risk, and Higher Inflamatory diet Scores Increased Risk. FOR APOEε4 CARRIERS, ONLY ADHERENCE TO THE RECOMMENDED FOOD SCORE APPEARED TO HELP DECREASE DEMINIA RISK.

Amaish Dave, Do, An Osteopathic Physician Specializing in Neurology, Who Was Not Involved in The Study, Commented With His Thoughts On The Findings:

“This Study Adds Hard Numbers to What We Know Intuitly Data Make these results hard to ignore. “

This Study Adds Information Enharding Potential Dietary Interventions Related to Dementia. There are limitations, Such as The Study Was Only in Participants in the UK, and Sub Information Comes from Participant Reporting. There may be restrictions on generalizability to other Groups, and Future Research Can Have More Diversity. Any General Limitations of the UK Biobank Also Apply to This Study.

Refectchers Note That the Self-Reporting of Food INTAKE INCREASES THE RISK OF RECALL BIAS; People Can Make Mistakes Such As incorrectly estimating portions and nutrients. They Also Note The Possibility of an Underestimation of the Association Between Diet and Risk for Dementia.

Participants were Between Ages 40 and 69 at Baseline, and Refers Only Did Follow-Up for Certain Timeframe. Suggest that using other follow-up periods and working dispute age Groups Coud Be Helpful, As This Coul Reveal Variation.

Diet Information Was Collected in a Narrow Window, and Refers Did Not Take Unto Account How Participants’ Diets Could Have Changed During the Follow-Up. The Refectchers Suggest that examining dietary changes could be Helpful in Truly Looking at the potential long-term impact of diet on People’s Chances of Developing Dementia.

Sub Dietary Data Was Lacking. For Example, Refers Note That They Lacked Information on How Much Olive Oil Participants Were Consuming, So They Weren’s Uble to Include This in the Scoring When Considering the Mediterranean Diet. Olive Oil is a Major Component of the Mediterranean Diet.

Refracchers Also Lacked Data from The Original Dietary Inflamatory Index, So They Only Incuded Sub Elements of This Index.

The Rebecchers ACKNOWLEDGE That the Use of Exact Matching in This Study Was Also Limiting. They explain that “The Estimated Effect Can Only Be Generalized to a Small Population and Lacks Precision.”

Finally, There is the Risk for Residual Confunding, Which Refers Acknowledge Coul Impact “Dietary Choices and Dementia Risk.”

This Study Highlights The Diet’s Important Role In Possibly Protecting Against Dementia. Alex Dimitriu, MD, Double Board Certified in Psychiatry and Sleep Medicine and Founder of Menlo Park Psychiatry & Sleep Medicine, Who Was Also Not Involved in The Study, Note The Following Clinical Implications of the Research:

“This Study Speaks to the importance of long-term adherence to diet and the benefits of this. It Also Demonstrates How Diet May Play A Greater Role for Older Women Than For Oher Groups. Also of Interest, The Study Confirms Prior Findings That Pro-Inflammatory Diet Fats, and refined carbohydraates) can be a risk factor formentia. ”

The Results Also Suggest The Need For Doctors To Keep Discussing Diets with ESIR CLIENTS. As noted by Dave:

“Doctors Should Be Talking To Patients About Brain-Healthy Diets Just Like We Talk About Heart Health. Eating Less Process Ed Food and More Whole, Anti-Inflammatory Foods Could Be a Powerful Tool Tool to Prevent Cognitive Decline. Prescription. “
