A cross-sectional study was conducted within the Spanish cohort of the European Prospective Investigation in Cancer and Nutrition to assess the principal food sources of vitamin C, vitamin E, alpha-carotene, beta-carotene, lycopene, lutein, beta-cryptoxanthin and zeaxanthin in an adult Spanish population. The study included 41446 healthy volunteers (25812 women and 15634 men), aged 29-69 years, from three Spanish regions in the north (Asturias, Navarra and Guipuzcoa) and two in the south (Murcia and Granada). Usual food intake was estimated by personal interview through a computerized version of a dietary history questionnaire. Foods that provided at least two-thirds of the studied nutrients were: fruits (mainly oranges) (51%) and fruiting vegetables (mainly tomato and sweet pepper) (20%) for vitamin C; vegetable oils (sunflower and olive) (40%), non-citrus fruits (10%), and nuts and seeds (8%) for vitamin E; root vegetables (carrots) (82%) for alpha-carotene; green leafy (28%), root (24%) and fruiting vegetables (20%) for beta-carotene; fruiting vegetables (fresh tomato) (72%) for lycopene; green leafy vegetables (64 %) for lutein; citrus fruits (68 %) for beta-cryptoxanthin; citrus fruits (43%) and green leafy vegetables (20%) for zeaxanthin. In conclusion, the main food sources of nutrients with redox properties have been identified in a Mediterranean country. This could provide an insight into the interpretation of epidemiological studies investigating the role of diet in health and disease.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-52046","resume","type-resume","status-publish","hentry"],"acf":{"auteurs":null,"adresse":null,"numero":null,"page":null,"mois":null,"annee":null,"mots-cles":null,"sources":null},"yoast_head":"\n
