| Abstract | ||||
| The present work is planned to estimate the daily total dietary intake of fluoride by the Egyptian citizen in diel and drinking waler in order to know Ihe effect of the fluoride level on general health and comparing this level with the international recommended acceptable limit. The daily intake of fluoride from diet was estimated using Ihe lolal diet sludy. The method involves the purchase and preparation of the cooked foodsluffs commonly used in the diet. However, it does not include food consumed outside Ihe home. These foodsluffs were combined into 12 groups of like foods as follow :- Bread and cereals; poultry; meal and meal products; fish; oil, tats, eggs and dairy products; sugars; vegetables; potatoes: canned vegetables; fresh fruit and fruil products: beverage and milk. Thirty samples, used In the house, from each of the twelve foodstuffs groups were collected monthly from 3 govemorates (Cairo. Giza . and Kalioubia) during the year 2003 and then estimate the fluoride concentration in each food group. The total fluoride intake ( mg / person / day) was calculated in Ihe different cited foodstuffs and was estimated to be: 0.374, 0.005, 0.009, 0.09, 0.07, 0.007, 0.001, 0.003, 0.019,0.0007,0.001 and 0.0017 mgl person / day, respectively. Consequently, the daily intake of fluoride from diet was 0.58 mg / person / day. Drinking water samples were collected from ten govemorates in Egypt. The fluoride content in tap water (the origin is River Nile) ranged from 0.330-0.377 mg / L with an average of 0.36 mgIL.The amount of drinking water consumed by the Egyptian citizen vary from 3188 \0 3375 ml J day for adult and consequently the fluoride intake from drinking water ranged from 1.147 • 1.215 mg / day. By comparing the results of the total fluoride intake in Egypt by the Egyptian citizen with the study presented by WHO 1984, it was found that the fluoride intake by the Egyptian citizen was 0.580 mg J person J day, whereas, the international fluoride intake was 0.344 mg / person / day. The average intake from tap water is estimated to be within the range of 1 to 1.5 mg I person! day (WHO, 1984). The present study found that the daily intake of fluoride from drinking water ranged from 1.147 to 1.215 mg I person I day. By calculation, the total intake of flUOride set by (WHO, 1984) from diel and drinking water vary from 1.344 to 1.844 mg / person / day, whereas, the present study found that the total intake of fluonne by the Egyptian citizen in Egypt ranged 1.727 to 1. 795 mg/ person! day. Consequently, the total intake of fluorine from diet and drinking water in Egypt by the Egyptian citizen falls within the safely recommended intemationallimit. | ||||
