objective: to assess the characteristics of patients with wet amd and low intake of lutein and zeaxanthin in our population. methods: a prospective, observational, cross-sectional study was conducted on patients with active wet amd. a full blood count, a lipid and liver profile, a dietary interview (24-hour recall), and an anthropometric study were performed. lutein-zeaxanthin (lz) intake results split the patents in two groups. group 1 ("sufficient" intake): patients with > 1,400mg/day intake in women and 1,700mg/day in men (2/3 of the average daily intake in a normal population). group 2: patients with daily intakes below that of group 1. a descriptive and comparative statistical study was performed. results: fifty-two patients with a mean age of 78.9 years. group 1: eleven patients (21% of the sample). group 2: forty-one patients. the subjects with adequate intake of lz had higher a body mass index and waist circumference. between 70-80% of patients in group 1 had inadequate intake of vitamin a, c and e and zinc. conclusions: seventy-nine per cent of the patients with wet amd have a deficient daily intake in lutein-zeaxanthin. the population with adequate intake is associated with an increased body mass index and waist circumference, and in addition, most of them have an insufficient intake of vitamin a, c, e and zinc.
