Background: The health benefits arising from the antioxidant vitamin E is well recognized and its recommended dietary intake for the general population have been established. However, there is still a need for assessing antioxidant vitamin intake in different population groups. Objective: To assess intake of antioxidant vitamin E and to identify its major sources in the diets of healthy premenopausal women from Extremadura. Material and methods: The study group consisted of 123 premenopausal women from Spanish population. Antioxidant vitamin dietary intake was assessed by individual 7-day records. Data was analyzed using updated “Spanish Food Composition Tables”. Results: The average daily intake of antioxidant vitamin E was: 2.58±0.85 mg/day.  Dietary vitamin E was around 76.54% lower than that recommended. Diets that were deficient in vitamin E were recorded in the 100% of the interviewed premenopausal women from Extremadura. Conclusions: The average intake of antioxidant vitamin E was not found to be in recommended range, no significant differences were observed between the lowest and the highest intake. They were no differences in the consumption of food products recognized as major sources of vitamin E in the study population. It is therefore necessary to increase the consumption of foods that provide a valuable dietary source for this vitamin.

This study aimed to compare calculated nutrient intakes from two different food composition databases using data from the European prospective investigation into cancer and nutrition (EPIC) cohort. Dietary intake data of the EPIC cohort was recently matched to 150 food components from the U.S. nutrient database (USNDB). Twenty-eight of these nutrients were already included in the EPIC nutrient database (ENDB—based upon country specific food composition tables), and used for comparison. Paired sample t-tests, Pearson’s correlations (r), weighted kappa’s (κ) and Bland-Altman plots were used to compare the dietary intake of 28 nutrients estimated by the USNDB and the ENDB for 476,768 participants. Small but significant differences were shown between the USNDB and the ENDB for energy and macronutrient intakes. Moderate to very strong correlations (r = 0.60–1.00) were found for all macro- and micronutrients. A strong agreement (κ > 0.80) was found for energy, water, total fat, carbohydrates, sugar, alcohol, potassium and vitamin C, whereas a weak agreement (κ < 0.60) was found for starch, vitamin D and vitamin E. Dietary intakes estimated via the USNDB compare adequately with those obtained via the ENDB for most macro- and micronutrients, although the agreement was weak for starch, vitamin D and vitamin E. The USNDB will allow exposure assessments for 150 nutrients to investigate associations with disease outcomes within the EPIC cohort.

Dietary fiber has been defined as the part of material in foods impervious to the degradative enzymes of the human digestive tract. The dietary fiber of plants is comprised of carbohydrate compounds including cellulose, hemicellulose, pectin, gums, mucilages, and a noncarbohydrate substance, lignin. These substances, which form the structure of plants, are present in the cell walls of all parts including the leaf, stern, root, and seed.1 Animal tissue also contains indigestible substances. Crude fiber and dietary fiber are not the same thing. Crude fiber refers to the residue left after strong acid and base hydrolysis of plant material. This process dissolves the pectin, gums, mucilages, and most of the hemicellulose and mainly is a measure of the cellulose and lignin content. Clearly, this method tends to underestimate the total amount of fiber in the food.1 Most food composition tables give only crude fiber values. Current interest in fiber was stimulated by the suggestion that it might help to prevent certain diseases common in the United States, namely diverticular disease, cancer of the colon, irritable bowel syndrome, obesity, and coronary heart disease.2-4 African blacks in rural areas where the fiber intake was high rarely had these diseases; however, during the past 20 years as this population moved to the cities and adopted Western habits (including a Western diet), they began to suffer from the same "Western-type" diseases. A high-fiber diet increases fecal bulk, produces softer, more frequent stools, and decreases transit time through the intestine.5 These factors may be responsible for the supposed beneficial effects of fiber.
