Dietary Exposure Of Nitrate

Dietary exposures to nitrate have been estimated for two different groups of uk consumers.

Dietary exposure of nitrate. Dietary nitrates and nitrites can also change into nitric oxide. The daily dietary exposure of the general population was estimated from the uk 1997 total diet study to be 52mg day. Vegetables contributed approximately 70 to this total dietary exposure. 3 7 mg kg 1 body weight day 1 for adults and 51 54 of the adi for children with the major contributors being for adults and children respectively vegetables 24 and 27 of adi potatoes 5 and 11 of adi and water 5 and 5 of adi.

Most models require the use of food consumption information and will therefore be flawed by the problems that exist with current dietary intake assessment methods. On exposure to high heat this combination creates the perfect conditions for nitrosamines to form. 24 in hong kong dietary exposure to nitrate from raw vegetables was estimated to be approximately 120 and 350 the adi for average and high vegetable consumers respectively. Models to assess dietary exposure of population groups to nitrates and nitrites should be based on the major sources of these substances in foods.
