Vitamin E (dl-α-tocopherol) occurs naturally in foods of plant and animal origin. Vitamin A plays an important role in the mechanisms associated with vision and vitamin E as an antioxidant. To evaluate the ingestion of vitamins A and E by the Portuguese population, through a Total Diet Study (TDS), using the daily reference doses, 800 μg and 12 mg, respectively for vitamins A and E, for adult subjects, analytical determinations in representative samples were done. Objectives: To determine the vitamins A and E contents of 228 composite samples representative of the consumption of the Portuguese population.engVitamin AVitamin EContentPortuguese ConsumptionComposite SamplesComposição dos AlimentosPortugalconference object
