Pattern of dietary and supplemental vitamin C intake according to the level of fruit and vegetable consumption

Although the prevalence of vitamin C insufficiency was high, regardless of FV sufficiency, supplementation allowed the FVS and FVINS groups to meet the recommended levels. Nevertheless, the quality of dietary sources remains a concern, with a reliance on less healthy options such as sugar-sweetened beverages and fruit juice products, particularly among young adults. These findings highlight the importance of promoting natural food sources like FV for better diet quality.
