Does the Mediterranean diet reduce dementia risk 20-year study hints no A 20-year study found no link between people's dietary habits in midlife and their later risk of dementia . Previous studies of the potential cognitive benefits of the so-called Mediterranean diet — broadly defined as a diet rich in vegetables, legumes, fruits, fish and unsaturated fats, such as olive oil, and low in dairy, red meats and saturated fats — have turned up mixed results, according to the National Institutes of Health's National Institute on Aging (opens in new tab) (NIA).However, two 2019 studies in the journal JAMA that included thousands of people and decades of follow-up found no evidence that the Mediterranean diet reduces dementia risk (opens in new tab), or that that diet quality affects dementia risk (opens in new tab), broadly.  Read more:

A"Mediterranean diet" does not lower the odds of developing dementia, a 20-year study from Sweden suggests.diversity of gut organisms is good , individual microbial mileage may vary.The study, conducted by PSE Healthy Energy, screened for more than 70 different compounds.Guardian reported .   Previous studies of the potential cognitive benefits of the so-called Mediterranean diet — broadly defined as a diet rich in vegetables, legumes, fruits, fish and unsaturated fats, such as olive oil, and low in dairy, red meats and saturated fats — have turned up mixed results, according to the National Institutes of Health's National Institute on Aging (opens in new tab) (NIA).However, two 2019 studies in the journal JAMA that included thousands of people and decades of follow-up found no evidence that the Mediterranean diet reduces dementia risk (opens in new tab), or that that diet quality affects dementia risk (opens in new tab), broadly. Even if healthy relationships between diverse taxa are eventually defined, the best way to quantify them and their ratios in the gut microbiome have yet to be standardized.  The new Swedish study casts further doubt on the diet's brain-bolstering benefits. The highest concentrations of benzene were found in the Los Angeles area, followed by the Bay Area."We did not find any association between either conventional dietary habits or adherence to a Mediterranean diet and subsequent incidence of dementia," first author Dr. In the experimental setting, most of the measuring techniques are based on"proprietary methods that lack validation in large cohorts," Kashyap said. Isabelle Glans (opens in new tab), a member of the Clinical Memory Research unit at Lund University in Sweden, told Live Science in an email. Researchers discovered that kids with parents who were identified as authoritarian or neglectful were more likely to gain more weight compared to children who experienced authoritative parenting, while parents identified as permissive didn’t have much impact on children’s weight, according to Fortune. These findings, which align with those found in prior studies of similar size and length, were published Oct. "Diet appears to help shape the microbiome community in the long term, but short-term interventions have limited effect on microbiota composition," Kashyap said. Let’s say that… We found the concentrations overall, including the Bay Area, were 10 times higher than what we found in Boston. 12 in the journal Neurology (opens in new tab).  That said, similar to previous studies, the research relied on self-reported dietary data from participants, which may not be wholly accurate and can somewhat skew the interpretation of the results. Defining a healthy microbiome or the methods by which it can be targeted, he said, are challenges yet to be met. Related: Brain 'pacemaker' for Alzheimer's shows promise in slowing decline  The effect of diet on dementia Physiologist Ancel Keys and biochemist Margaret Keys, a husband-wife duo, derived the Mediterranean diet from Ancel's influential research on the link between men's diets and their risk of heart attack and stroke. In every sample, except for one, benzene was found. The research suggested that diets low in saturated fat protect against cardiovascular disease, and Ancel and Margaret drew loose inspiration from Greek, Italian and other Mediterranean cuisines to write their popular diet books, according to The Conversation (opens in new tab). The intestinal microbiome is a"complex ecosystem," Teigen added. In theory, by guarding against cardiovascular disease, the Mediterranean diet could indirectly reduce the risk of dementia, according to the NIA. That's because plaque build-up in arteries (atherosclerosis), strokes, high blood pressure, high blood sugar and diabetes may all raise the risk of dementia, and maintaining a healthy diet can help lower the risk of these conditions. The composition, or what microbes are there, is only one piece of the puzzle and it doesn't tell us much in isolation. Health experts said if benzene accumulates in the body over a person's lifetime, it can increase health risks. The Swedish study does not completely overturn this idea, but it suggests that diet alone does not exert a notable influence on the course of cognitive function in later life. "Diet as a singular factor may not have a strong enough effect on cognition, but is more likely to be considered as one factor embedded with various others, the sum of which may influence the course of cognitive function," Dr. The amplicon approach, which generally relies on profiling of the 16S rRNA gene, is less expensive and has the advantage of detecting taxa in low abundance. Nils Peters (opens in new tab), a neurology specialist at the Stroke Center Klinik Hirslanden in Zurich, Switzerland, and Benedetta Nacmias (opens in new tab), an associate professor of neurology at the University of Florence, wrote in an Oct. He said the only sure way to avoid exposure is to get rid of gas appliance. 12 commentary (opens in new tab) published in Neurology. Shotgun sequencing involves genome analysis through small fragments of DNA that are sequenced individually.  These other factors include exercising regularly; avoiding smoking; drinking only in moderation; and keeping one's blood pressure in check, they wrote. In particular, evidence suggests that regular physical activity and consistent blood pressure control are protective against cognitive decline, and that these factors are likely more influential than diet, according to the NIA (opens in new tab). Both technologies are commonly used in experimental efforts to characterize and understand the activity of the gut microbiome, but neither can reliably reveal the degree to which microorganisms in the gut are contributing to risk for disease in general or to specific diseases.S. The new research included data from about 28,000 people who took part in the Malmö Diet and Cancer Study, a study launched in the Swedish city of Malmö in the 1990s. At the study's start, the participants were 58 years old, on average; at that time, they provided dietary data in the form of a week-long food diary; a detailed questionnaire about the frequency and quantity at which they consumed various foods; and an interview about their dietary habits. This overlap becomes confusing quickly, because"there is also functional redundancy so that multiple taxa can perform the same function," Teigen said. Based on this information, the research team"scored" each participant on how strictly they adhered to standard Swedish dietary recommendations or to a specific version of the Mediterranean diet. The Thursday in Environmental Science and Technology.  Related: A major Mediterranean diet study was retracted. Recent studies have used AI to determine why postprandial glucose responses (PPGRs) vary in people with similar diets. But do docs still recommend it? Over the next 20 years, 1,943 people, or 6.9% of the participants, were diagnosed with some form of dementia. Kashyap said that he sees several clinical applications in the future, including the potential for direct-to-consumer tests that not only characterize the microbiome but also use patient-specific factors within an algorithm to guide intervention. These diagnoses included the two most common forms of dementia: dementia related to Alzheimer's disease (AD) and vascular dementia, which arises from poor blood flow to the brain.   Participants who stuck to either a conventional diet or to the Mediterranean diet did not have a lower incidence of either type of dementia than participants who did not adhere well to either, the researchers found. Despite current limitations, research is active, and Teigen is not alone in predicting that relationships between the microbiome and disease will eventually be understood. They also found no link between diet and a specific marker of Alzheimer's disease, which they screened for in about 740 of the participants with cognitive decline.

Again, the problem is not just proving a relationship between any specific microbiome profile and health risks or health benefits, but proving that the microbiome can be altered to reduce these risks. Here's how it's different. —Electrical stimulation makes old brains act young again  Overall, the study"does not indicate a specific effect of diet on the course of cognitive function," Peters and Nacmias wrote. Kashyap agreed. But like similar studies conducted in the past, the work does have its limitations, they noted. For example, the baseline dietary information gathered from each participant may not reflect how their diet has changed through time. Kashyap reports financial relationships with Intrinsic Medicine, the IP Group, Novome Biotechnologies, and Pendulum Therapeutics. What's more, study participants may have somewhat misreported their true dietary habits.  The best way to test the long-term effect of the Mediterranean diet on cognition would be to run a long-term randomized controlled trial. Teigen reports no potential conflicts of interest. In such a trial, groups of participants would be asked to follow specific diet plans, or even given all their food, for a long period of time and they'd be monitored for signs of dementia throughout.   "However, it is probably not feasible to design a 20-year randomized controlled trial with strict dietary habits to adhere to," the study authors wrote in their report. Some shorter term trials of this type can be found on the NIA website and the Alzheimers.gov Clinical Trials Finder (opens in new tab). However, for now, the available evidence suggests that the Mediterranean diet is not a silver bullet for dementia prevention. .
