The research team brings together experts in nutrition, statistics, and public health from multiple institutions, leveraging research expertise alongside the practical experience of clinicians and clinical nutritionists in health promotion. Additionally, an international expert advisory group provides guidance on research direction, enhances strategic planning, and supports the effective implementation of fortification strategies. This project also collaborates with the National Nutrition Care Strategy Development Team, jointly conducting data analysis and collaborative meetings to design evidence-based fortification strategies for different life stages in response to the current nutritional deficiencies in Taiwan. National nutrition surveys indicate widespread deficiencies in vitamin D and calcium among all age groups from the age of four onward, with women and vegetarians being particularly at risk. Dietary fiber intake is critically low across all demographics, and over 80% of individuals aged 13 and above fail to meet the recommended intake for essential minerals such as magnesium and zinc. Additionally, despite long-standing policies on iodine fortification in table salt, median urinary iodine levels suggest that more than half of the population is iodine deficient. To address these pressing nutritional issues, the project is structured into four specialized working groups, including the Calcium and Vitamin D Fortification Strategy Working Group, the Dietary Fiber, Magnesium, and Zinc Fortification Working Group, the Taiwan Salt Iodization Policy Analysis and Strategic Evidence Working Group, and the Nutritional Epidemiology and Statistics Core Working Group. In the first year of the project (2024), the team will conduct literature reviews, big data analysis, and domestic and international expert workshops to identify key nutrient deficiencies and the barriers preventing different life stages from achieving recommended intake levels. These findings will be prioritized through expert consensus. The project will also assess and catalog existing fortified foods in Taiwan, referencing large-scale national and international research and evaluating global nutrition fortification policies, their implementation methods, effectiveness indicators, and outcomes. The research will explore two primary fortification approaches: conventional nutrient fortification, which involves the direct addition of nutrients to foods, and food-to-food fortification, which leverages naturally nutrient-rich foods to enhance other foods. These findings will inform the development of nutrition fortification policies tailored to Taiwan’s needs. Building on the first year’s research outcomes, the second year (2025) will focus on conducting pilot intervention trials targeting specific nutrient deficiencies across different life stages. These trials will evaluate the acceptability and effectiveness of fortified foods in improving nutritional status, serving as a foundation for future fortification policy advocacy and implementation. The project will continue literature reviews, big data analysis, and expert consultations, using scientific evidence to investigate underlying causes of nutrient deficiencies. Additionally, the initiative will establish an online nutrition education platform, promote locally adapted high-fiber recipes, and encourage public engagement in healthier dietary practices. The project will also develop a long-term, phased implementation plan for nutrient fortification in Taiwan, providing standardized guidelines for execution. The passage of the Nutrition and Healthy Diet Promotion Act in 2023 has provided Taiwan with a strong legal foundation for advancing national nutrition policies. This research project aligns with these policy efforts by focusing on the most urgent nutritional issues, particularly calcium, vitamin D, dietary fiber, magnesium, and iodine deficiencies. By designing diverse fortification strategies and policy guidelines, leveraging domestic and international expert resources, and conducting pilot intervention trials, this initiative seeks to improve nutritional health across all life stages, ultimately contributing to a healthier future for the entire population.2023年「營養及健康飲食促進法」的通過，賦予我國推動營養及健康飲食促進之法源依據，有系統地推動飲食與營養教育、營造正向健康的飲食文化。「營養及健康飲食促進法」分為四大面向：完備行政支持系統、確保健康飲食、營造健康飲食支持環境及推動營養及健康飲食教育。其中「確保健康飲食」則需完備營養調查等基礎資料及研究，訂定人民營養及飲食建議攝取基準，「營造健康飲食支持環境」將營養問題納入社會救助補計畫，以及鼓勵依據人民缺乏特定營養素而有營養不良時添加特定營養成分。透過強化政府在營養政策上的執行能力，經由營養調查建立基礎資料，提供人民飲食建議基準，結合社會力量，推動營養素強化以改善營養不足缺口並提高全民營養知識與健康行為。 國民營養調查顯示：國人維生素D與鈣不論性別於四歲後均缺乏，尤以女性與素食者缺乏更為顯著，維生素D攝取不足與血清25(OH)D濃度呈正相關。鈣的營養不佳難以透過橫斷性資料直接觀察，但研究證實維生素D攝取對健康的顯著性影響。此外，全年齡層國民膳食纖維攝取嚴重不足，超過八成的13歲以上國民礦物質鎂、鋅攝取不足，施行多年的食鹽中碘添加濃度政策，國人尿碘的分析數值僅在中位數，顯示有半數以上的人是缺乏的，而碘營養問題在45歲以上人群與孕婦中尤為明顯。 為改善國人已存在營養失衡的問題，本研究計畫的主旨為建構不同生命週期特定營養強化策略藍圖。本研究團隊結合國內跨校營養、統計、公衛之專家與研究能量，並結合臨床醫師、臨床營養師團隊的實務經驗與健康推廣經驗，同時設有國際專家團隊，指導本研究計畫研擬方向、強化策略擬定與執行。並與[建構不同生命週期營養照護策略團隊]，互助研究分析資料、召開協同會議，以國人目前營養缺乏問題，給予不同生命週期的強化策略藍圖。 本計畫依國人目前最迫切缺乏的營養素、相對應存在不同生命週期的健康問題、並考量營養強化策略的安全性與可行性，劃分為四個工作小組（鈣及維生素D強化策略工作小組、膳食纖維及鎂鋅強化工作小組、台灣食鹽加碘政策之研析與策略實證工作小組、營養流病及統計核心工作小組）。將於本年度（113年，計畫第一年）藉由進行文獻探討、大數據分析、舉辦國內外專家工作坊、邀請各領域專家舉辦專家會議，找出在特定營養素缺乏的問題，以及各生命週期所面臨之無法達成建議攝取量的難處與面臨的亞健康問題，並由國內外專家會議進行優先順序排列。盤點並整理台灣現有之營養強化食品，透過國內外大型調查研究與文獻資料，以及國際間目前已施行營養強化政策的執行方式及可能的成效評價指標及執行成果，以營養素強化食品（conventional fortification）以及食品強化的食品（food‐to‐food fortification），提供民眾所缺乏的營養素強化食品並擬定營養強化政策。 參照第一年的研究成果，本計畫擬於第二年（114年）選定特定營養素缺乏之不同生命週期進行介入的先導試驗，評估食品強化食品的接受度及營養狀況改善程度，作為營養素強化倡議與政策的推廣。計畫將持續進行國內外文獻探討與大數據分析，結合國內外專家意見，以科學證據為基礎，推動營養不足原因的深入研析，並開設營養學習專區，推廣本土化高纖食譜，提升全民知能與實踐意願，綜合評估成效作為營養素強化倡議與政策推動之參考，並制定國人需強化營養素之分年執行與推動規劃，以提供標準化執行之參考。 「營養及健康飲食促進法」的施行為國內營養政策推動奠定堅實基礎。本計畫聚焦於國人最迫切的營養問題，針對鈣、維生素D、膳食纖維、鎂及碘等營養素，設計多元化強化策略與政策指引，結合國內外專家資源及先導試驗，努力改善全生命週期的營養健康狀況，最終實現全民健康的長期目標。營養食物強化鈣維生素D膳食纖維碘流行病學NutritionFood fortificationCalciumvitamin DDietary fiberIodineEpidemiologyProject
