This study assessed daily vitamin A intake from common foods consumed in China and found it to be significantly below the recommended dietary reference intake. Vegetables were identified as the largest contributor to intake, but their consumption alone is unlikely to meet guidelines, suggesting strategies like vegetable biofortification and fortified oils.
The study estimated the daily vitamin A intake of Chinese residents by analyzing the vitamin A content and consumption data of various foods. Vegetables contributed the most, accounting for 54.94% of intake (253.03 µgRAE/day), with carrots, spinach, and Chinese chives being top sources. The authors calculated that consuming specific quantities of these vegetables could meet the recommendation, but this would require amounts exceeding typical dietary habits. Consequently, they propose increasing the vitamin A concentration in vegetables through breeding or biofortification and fortifying common vegetable oils like rapeseed and soybean oil.
