Conquering today’s health paradox with the power of Heal – an expert consensus report plus research priorities and policymaker roadmap
Background: Despite growing scientific evidence and health guidelines, the global health paradox persists, with rising lifestyle-related diseases and escalating healthcare costs exposing the inadequacy of current efforts. Objective: Three multidisciplinary congresses were held to generate evidence-based conclusions aimed at addressing the global health paradox. Methods: A total of 58 experts from 62 entities participated in the international rese…
Sex Differences in Training Behaviors of 10 km to Ultra-Endurance Runners (Part A)—Results from the Nurmi Study (Step 2)
Training for running events is fundamental for successful participation in various running events such as 10 km, half-marathon, marathon, or ultra-marathon distances. Training behaviors are likely based on runner motivations and social constraints, particularly for females. Participants completed a questionnaire following a cross-sectional approach, including questions on sociodemographics, general training behaviors, and periodization training s…
Sex Differences in Racing History of Recreational 10 km to Ultra Runners (Part B)—Results from the Nurmi Study (Step 2)
Sex differences in anatomy and physiology are the primary underlying factor for distinctions in running performance. Overall participation in recreational running events has been dominated by males, although increasing female participation has been reported in recent years. The NURMI study participants filled in a survey following the cross-sectional study design with questions on sociodemographic data, running and racing motivations, training be…
Dietary intake of vitamin B 6 and concentration of vitamin B 6 in blood samples of German vegans
Objective The study aimed to evaluate the dietary vitamin B 6 intake and determine the vitamin B 6 concentration in blood samples of German vegans. Design and setting Cross-sectional study with 33 examination sites all over Germany. Subjects Ninety-three vegans (50 females) with a mean (±standard deviation (SD)) age of 43.7 ± 15.7 years who took no vitamin supplements. Methods Dietary intake was assed using a semi-quantitative food-frequency ques…

The new nutrition science project
Objective To show that nutrition science, with its application to food and nutrition policy, now needs a new conceptual framework. This will incorporate nutrition in its current definition as principally a biological science, now including nutritional aspects of genomics. It will also create new governing and guiding principles; specify a new definition; and add social and environmental dimensions and domains. Method A narrative review of nutriti…
The principles, definition and dimensions of the new nutrition science
Objective To specify the principles, definition and dimensions of the new nutrition science. Purpose To identify nutrition, with its application in food and nutrition policy, as a science with great width and breadth of vision and scope, in order that it can fully contribute to the preservation, maintenance, development and sustenance of life on Earth. Method A brief overview shows that current conventional nutrition is defined as a biological sc…
Wholesome nutrition: A suitable dietfor the new nutrition science project
Objective To show that the practice of wholesome nutrition meets the demands of the concept of the new nutrition science, at present and in the future. Method To define ‘wholesome nutrition’, to describe its origin and to discuss its recommendations; and to cite practical examples showing that wholesome nutrition includes the dimensions and domains that are the basis of the concept of the new nutrition science. Conclusion The recommendations of w…

Homocysteine and cobalamin status in German vegans
Objective: The study aimed to evaluate the homocysteine and cobalamin status of German vegans and determine whether the intake of very small amounts of foods of animal origin can improve this status. Design and setting: Cross-sectional study, Germany. Subjects: The dietary and nutritional intakes of 131 vegans (73 women, 58 men; a range: 20.2–82.1 years) were evaluated using a general questionnaire and two food–frequency questionnaires. Results: …
Nutrition ecology: The contribution of vegetarian diets
Migration and nutrition in Thailand
The consumption frequencies of different food items of migrants and settled families were investigated by the interview method. Additionally, demographic and socioeconomic data were collected. In contrast to many other studies, the Thai migrants investigated here showed an increase in consumption frequencies for many food items and they consumed a greater variety of foods after migration. This occurred in spite of a shift from subsistence economy…
