“…The findings of the current study are consistent with those of Deolalikar [54], who found that adequate childhood nutrition can also improve educational attainment and economic growth per capita. Population growth as a socio-economic indicator is positively associated with food consumption, which supports the idea that an increased and healthier food consumption reduces mortality rates [55] and may upsurge life expectancy [56]. However, in developed countries, increased food consumption is a major cause of obesity and can reduce the expected lifetime [57].…”

Grand Challenges in Central Europe: The Relationship of Food Security, Climate Change, and Energy Use

Pursuing various sustainable development goals is posing new challenges for societies, policymakers, and researchers alike. This study implements an exploratory approach to address the complexity of food security and nuance its relationship with other grand challenges, such as energy use and climate change, in Central European countries. A multiple factor analysis (MFA) suggests that the three pillars of food security relate differently to climate change: food affordability and food accessibility positively correlate with climate change, while food quality has a negative association with temperature rise. However, if countries switched to renewable energy resources, all three pillars of food security could be achieved simultaneously. The study also underlines regional inequalities regarding grand challenges and emphasizes the need for innovative local solutions, i.e., advances in agriculture systems, educational programs, and the development of environmental technologies that consider social and economic issues.

“…Second, the Japanese intake of meat and dairy products is considered low by global standards [5]. In addition, Japanese individuals eat a wider diversity of foods [5]. Therefore, the present findings may not be generalised to Western populations who consume larger amounts of meat and a smaller variety of foods.…”

“…The Japanese diet is characterised by a wide variety of seasonal ingredients and abundant aquaculture products [4]. An international comparative study reported that Japan demonstrated the highest values for healthy life expectancy and the second highest values for dietary diversity among 137 countries, and dietary diversity was positively associated with healthy life expectancy, even after controlling for gross domestic product [5]. We previously hypothesised that multiple nutritional deficiencies caused by an unbalanced diet might be a risk factor for cognitive decline and found that higher dietary diversity was associated with better cognitive function among older Japanese subjects [6].…”

Dietary diversity is associated with longitudinal changes in hippocampal volume among Japanese community dwellers

Background/Objectives Dietary habits are known to affect health, including the rate of brain ageing and susceptibility to diseases. This study examines the longitudinal relationship between dietary diversity and hippocampal volume, which is a key structure of memory processing and is known to be impaired in dementia. Subjects/Methods Subjects were aged 40-89 years (n = 1683, men: 50.6%) and participated in a 2-year follow-up study of the National Institute for Longevity Sciences-Longitudinal Study of Aging. Dietary intake was calculated from 3-day dietary records, and dietary diversity was determined using the Quantitative Index for Dietary Diversity at baseline. Longitudinal changes in hippocampal and total grey matter volumes were estimated by T1-weighted brain magnetic resonance imaging and FreeSurfer software. Estimated mean brain volume change in relation to dietary diversity score quintiles was assessed by the general linear model, adjusted for age, sex, education, smoking status, alcohol intake, physical activity, and comorbidities. Results The mean (± standard deviation) % decreases in hippocampal and total grey matter volume during the 2-year followup were 1.00% (±2.27%) and 0.78% (±1.83%), respectively. Multivariate-adjusted decreases in total grey matter volume were associated with dietary diversity score (p = 0.065, p for trend = 0.017), and the % decrease in hippocampal volume was more strongly associated with the dietary diversity score: the estimated mean (± standard error) values were 1.31% (±0.12%), 1.07% (±0.12%), 0.98% (±0.12%), 0.81% (±0.12%), and 0.85% (±0.12%), according to dietary diversity quintiles in ascending order (p = 0.030, p for trend = 0.003). Conclusions Among community dwellers, increased dietary diversity may be a new nutritional strategy to prevent hippocampal atrophy.

Imagining a habitable planet through food and health

Background and objectives Whether and how it might be possible to imagine a habitable planet through food and health. Methods Reflection on childhood happenstances, sociodemographic circumstances, educational opportunities, persons of influence and lifetime experiences insofar as they might have shaped a view of the past, present and future world as the sole rational home of us all. Confirmation of these notions by personal, kindred, and other contemporary records and publications. Results The need to live with uncertainty and an appreciation of connectedness with things animate and inanimate; and for this to be belief, identity, reason and professional imprimatur. That these things have unwittingly informed a near lifetime of interest and enthusiasm for how food and health systems are best served by socioecological approaches. Conclusions That we are socioecological beings with a destiny dependent on reconciling ourselves, as earthlings, as to how well we keep our place in the cosmos habitable. To that end we must dream and work. Prologue of the Dreamer An indelible event in my formative years was a teachers report. Whether the reason or not for the charge, I had skipped a grade and found I could get through the assigned work in the next grade ahead of schedule, with time to spare. The report said that I had limited life prospects since I was a dreamer. When I ultimately graduated in medicine, I arranged with the school to establish an annual award for creativity. I wanted no role in the way this would be done. After 3 years of deliberation, a teachers' panel resolved that the award should be based on a student initiative which demonstrated imagination and innovation. It was what I would have wanted as a student of the same school. Now and again I return to the school to share the joy that the awarded students experience at recognition of their creativity. My privilege now is to be a teacher, doctor and parent investing in present and future generations, given to dreaming and imagination.
