Abstract

Vitamin E status of agricultural migrant workers representing low socioeconomic population of Southern Brazil was evaluated by determining dietary intake and plasma levels of vitamin E. The mean plasma vitamin E level of 85 female and 39 male subjects was 1.14 ± 0.33 mg/100 ml or 2.27 ± 0.53 mg/g of total lipids in plasma. The difference between the plasma vitamin E values of male and female subjects was insignificant. Using various criteria for the assessment of plasma vitamin E levels, it was established that plasma vitamin E expressed in terms of plasma total lipids is a better indicator of vitamin E status. The actual mean α-tocopherol intake of this population was 5.51 ±3.30 mg/person from a typical diet supplying about 1500 kcal/day. On a 2500 kcal basis, the estimated mean α-tocopherol intake would be about 9 mg/day which compares favorably with the intake values reported for well-nourished populations. The main dietary source of vitamin E in this population is the traditional rice and beans diet with increased use of soybean oil and vegetable oil products in recent years. On the whole the vitamin E status of this Brazilian population is quite satisfactory despite inadequacies in their intake of dietary calories and other essential nutrients. The plasma vitamin E status of these subjects supports the dietary data for the intake of vitamin E in this population.
