Advances in Nutrition: An International Review This article shows that while the MIND diet may be effective in North American populations, the evidence for other populations is inconclusive.
Brain function gradually declines with age, which can lead to dementia, including Alzheimer’s disease, the most common form of dementia, accounting for 60-70% of dementia cases worldwide. Masu. The World Health Organization (WHO) estimates the number of people with dementia worldwide at 55 million. This number is expected to reach approximately 78 million by 2030 and 139 million by 2050. Furthermore, the global economic burden of dementia is expected to increase to $2.8 trillion by 2030.
You can’t stop your brain from aging. Furthermore, despite advances in medicines that delay the onset and slow the progression of dementia, there is no known cure. As a result, there is growing interest in the relationship between modifiable lifestyle factors and optimal brain aging. Nutrition, in particular, is considered a key modifiable lifestyle component that may play a pivotal role in the prevention and management of dementia.
Recently, nutrition researchers have shifted from studying the relationship between individual nutrients and foods and brain aging to studying the relationship between overall dietary patterns and brain aging. Studying dietary patterns is considered to be a more effective strategy as it allows you to obtain the synergistic effects of individual nutrients and foods.
Mediterranean Diet Approach to Systolic Hypertension The Dietary Intervention for Delayed Neurodegeneration (also known as the MIND diet) was designed to maintain good brain function as we age. As the name suggests, the MIND diet is a combination of the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) diet, which emphasizes the intake of neuroprotective food groups such as berries and leafy green vegetables. I am.
The question is Is the MIND diet effective? In response, the authors of The MIND Diet for the Aging Brain: A Systematic Review advances in nutrition, conducted a systematic scientific review of the evidence. To conduct the study, the authors analyzed the results of 40 of his studies. Only two of his studies were randomized controlled trials, often considered the gold standard for research studies, in which researchers randomly assign participants to experimental and control groups. His other 38 studies were observational studies, in which researchers observed individuals without manipulation or intervention.
Specifically, the authors sought to examine the relationship between the MIND diet and cognitive function, cognitive decline, and dementia risk. Additionally, the authors investigated how the MIND diet affects the incidence of age-related neurodegenerative diseases such as Parkinson’s disease.
According to the authors’ findings, “the majority of studies show that the MIND diet reduces the risk of all-cause dementia and Alzheimer’s disease.” The authors cautioned, “However, our findings do not conclusively prove the benefits of the MIND diet on brain aging.” Specifically, “the only good-quality randomized controlled trial showed no protective effect.”
The authors write that the mixed results of the systematic review suggest that “many of the cohorts that showed a protective association were of North American origin, raising the question of whether the most favorable diet for healthy brain aging is population dependent. “There is,” he pointed out. The authors further noted that “some of the studies conducted outside North America showing beneficial associations have adapted the MIND diet to local dietary habits.” As a result, “further research is needed to determine whether traditional dietary habits that include components of the MIND diet are more effective at preventing brain aging than the original MIND diet.”
