New Training Program in Japan Aims to Enhance Evidence-Based Nutrition Research

IUHW Vice President Naoko Yamamoto emphasized that the training program aligns with the three key pillars established at the Tokyo Nutrition for Growth Summit in 2021, where Japan played host. The first pillar encourages leveraging private companies' innovation to enhance consumer choices in nutrition.

Historically, global health policies have primarily utilized regulatory measures to promote healthy eating, such as taxing high-sugar and high-salt products. The Tokyo Summit marked a shift in focus towards harnessing the product development capabilities of companies to improve nutrition standards.

The second pillar addresses the need for more representative research focused on Asia, as much of the existing data is skewed towards Europe and the United States, often due to language barriers that limit inclusivity. Yamamoto noted that dietary habits in Asia differ significantly from those in the West, and increased research is needed to reflect these cultural differences.

Another goal outlined at the summit was to promote Japan's universal health coverage initiatives, ensuring equitable access to nutrition and health services for everyone. While the Tokyo Summit was held in conjunction with the Olympic Games, Yamamoto observed that subsequent discussions, particularly leading up to a 2025 conference in Paris, shifted away from the Asian-focused perspectives emphasized in Tokyo, with controversial issues surrounding ultra-processed foods coming to the forefront.

Yamamoto pointed out the necessity for scientific evidence to bolster international advancements in these areas and highlighted a deficiency in research regarding how Japanese food and nutrition contribute to longevity. The newly established program aims to fill this gap, training professionals to clarify healthy dietary standards for the Japanese population and share their findings worldwide.

Set to commence in 2025, this initiative will include a preparatory course for adult professionals, followed by graduate lectures starting in April 2026. The program aspires to address contemporary concerns such as the rise in obesity among children in the Pacific Islands, due in part to inexpensive access to sugary beverages and fast food.

Yamamoto cautioned against labeling all processed foods negatively, advocating for discussions around the broader food environment and overall dietary balance. For example, while instant noodles are often criticized, they may serve practical purposes during emergencies.

Additionally, she highlighted the mismatches between Western nutritional guidelines and Japan's unique dietary challenges, such as the prevalence of both obesity and undernutrition. An analysis published in The New England Journal of Medicine indicated that while many Japanese adults are overweight, a significant portion also falls under the underweight category, illustrating the complexity of malnutrition across the region.

Issues surrounding the evaluation of food have also arisen, particularly in how global standards often misrepresent Japanese culinary practices. Yamamoto expressed concern that inaccurate assessments could disadvantage Japanese companies and disincentivize their innovations aimed at enhancing nutrition.

The new IUHW program will explore innovative approaches to nutritional assessments rooted in Japanese food culture, with plans to offer similar professional courses in the future.
