Carotenoids have been linked with protective roles against diseases associated with aging, including cancer, cardiovascular disease, cataracts, and age-related macular degeneration. With data from a semiquantitative, validated FFQ, we examined carotenoid intake of 340 Puerto Ricans, 98 Dominicans, and 146 non-Hispanic whites (>60 y old) in Massachusetts. Compared with non-Hispanic white men, Hispanic men reported a higher intake of lycopene and lower intakes of alpha-carotene, lutein + zeaxanthin, beta-carotene (from diet only), and total beta-carotene (diet and supplements) (P < 0.001). Hispanic women reported higher intakes of beta-cryptoxanthin and lycopene but lower intakes of lutein + zeaxanthin (P < 0.001) than non-Hispanic white women. The frequency of consumption of fruit and vegetables was higher among Hispanic women, relative to non-Hispanic white women (P < 0.05). Plasma concentrations of alpha-carotene and lycopene were higher in Hispanic than in non-Hispanic white men and women. For both ethnic groups, higher intakes of carotenoids were associated with higher plasma concentrations of the respective carotenoids, except for lycopene (Hispanics) and lutein + zeaxanthin (non-Hispanic whites). Food sources contributing most to total intakes differed among the groups. The major sources of alpha- and beta-carotene were carrots for non-Hispanic whites and winter squash for Hispanics. The major source of lycopene was cooked tomato products for Hispanics, and pasta dishes for non-Hispanic whites. Traditional foods such as beans and plantains were also important contributors of carotenoids for Hispanics. Because of the potential importance of carotenoids as protective factors against chronic diseases, more attention to food-related practices associated with carotenoid intake in differing population groups is warranted.
类胡萝卜素与预防包括癌症、心血管疾病、白内障和年龄相关性黄斑变性在内的与衰老相关疾病具有保护作用。利用来自半定量、经过验证的食物频率问卷(FFQ)的数据,我们调查了马萨诸塞州340名波多黎各人、98名多米尼加人和146名非西班牙裔白人(年龄>60岁)的类胡萝卜素摄入量。与非西班牙裔白人男性相比,西班牙裔男性报告番茄红素摄入量较高,而α-胡萝卜素、叶黄素+玉米黄质、β-胡萝卜素(仅来自饮食)和总β-胡萝卜素(饮食和补充剂)摄入量较低(P<0.001)。与非西班牙裔白人女性相比,西班牙裔女性报告β-隐黄质和番茄红素摄入量较高,但叶黄素+玉米黄质摄入量较低(P<0.001)。相对于非西班牙裔白人女性,西班牙裔女性食用水果和蔬菜的频率更高(P<0.05)。西班牙裔男性和女性的血浆α-胡萝卜素和番茄红素浓度高于非西班牙裔白人男性和女性。对于这两个种族群体,除了番茄红素(西班牙裔)和叶黄素+玉米黄质(非西班牙裔白人)外,较高的类胡萝卜素摄入量与相应类胡萝卜素的较高血浆浓度相关。不同群体中对总摄入量贡献最大的食物来源不同。非西班牙裔白人中α-和β-胡萝卜素的主要来源是胡萝卜,而西班牙裔中是南瓜。西班牙裔中番茄红素的主要来源是煮熟的番茄制品,非西班牙裔白人中是面食。豆类和大蕉等传统食物也是西班牙裔类胡萝卜素的重要来源。由于类胡萝卜素作为慢性病保护因素的潜在重要性,有必要更多地关注不同人群中与类胡萝卜素摄入相关的饮食行为。
