Dietary exposure of Hong Kong adults to nitrate and nitrite from vegetable intake.

The aim of this study was to assess the dietary exposure of adults in Hong Kong to nitrate and nitrite from vegetables. If all vegetables consumed were raw, the dietary exposure to nitrate for average consumers was estimated to be 4.4 mg kg(-1) body weight (bw) day(-1) and, for high consumers, was estimated to be 13 mg kg(-1) bw day(-1), which is about 120 and 350% of acceptable daily intake (ADI), respectively.
