Abstract

<p>Objective: This study compared daily intake recommendations and classification of foods as vegetables in food-based dietary guidelines (FBDGs) from other countries with the vegetable intake recommendations in Health Japan 21 (second term).</p><p>Methods: We extracted the recommended values and the evidentiary basis for setting these vegetable intake recommendations from the FBDGs of 30 countries. Classifications of foods inconsistently identified as vegetables (i.e., vegetable juice, potatoes and other tubers, and beans) and foods for which intake habits were likely to differ across regions (i.e., pickled vegetables, mushrooms, and algae) were also compared.</p><p>Results: As in Japan, vegetables were recommended as an independent food group in 19 countries, and intake recommendations ranged from 160 to 900 g/day. In nine countries, intake recommendations were provided for vegetables and fruits combined. In two countries, intake recommendations were provided for vegetables and legumes combined, with recommendations varying from 300 to 1,100 g/day. The FBDGs of 19 countries (including Japan) explained their rationales for setting the recommended intake values. Almost all FBDGs specified whether potatoes and beans were classified as vegetables—over 70% of the FBDGs did not classify them as vegetables. Vegetable juice was excluded from the vegetable group in 12 countries but was included in 16 countries, including Japan. Mushrooms were considered a vegetable in all countries except Japan. The FBDGs of 11 countries did not mention mushrooms.</p><p>Conclusions: Differences in food culture across countries and regions made it challenging to compare other countries' vegetable intake recommendations with those of Japan.</p>
