Mediterranean Diet Associated with 41% Risk Reduction for AMD

Protecting a patient’s eyes may be more heavily influenced by diet than previously thought.

A new study, which analyzed data from a pair of previous study populations, found that people aged 55 and over who maintained a Mediterranean-style diet reduced their risk of developing late-stage age-related macular degeneration (AMD) by 41%.

Investigators, led by Bénédicte MJ Merle, PhD, of the French Institute of Health and Medical Research, found their findings supported the suggestion that healthful, nutrient-rich foods including fruits, vegetables, legumes, and fish have a role in the prevention of AMD.

The study analyzed the data from 2 previous studies which followed participants in multiple regions in Europe for several years. The first was the Rotterdam study, in which patients aged 45 ayear nd older in the Netherlands were followed more than 21 years, with investigators examining patients and giving them questionnaires about their diets once every 5 years. The study began recruiting participants in 1990. Investigators collected information on a variety of health outcomes, including ophthalmologic, neurodegenerative, and cardiovascular diseases. It also asked the patients about their socio-economic status, alcohol consumption, dietary habits and more.

The second study was the Alienor study, in which patients aged 65 years and older were seen by ophthalmologists every 2 years, beginning in 2006, but only followed over a four-year period so far. Participants in the Alienor study are recruited from the Three-City study, which has been following patients in several regions of France.

Nearly 5000 (n= 4996) participants from the previous studies were included in the current study, 155 of which experienced advanced AMD. The majority of the patients, 4446 (88.96%), came from the Rotterdam study, while the other 550 came from the Aleinor study. The investigators used the MeDi, a scale designed to assess how closely a person’s diet matches the Mediterranean diet. For example, the scale will attribute a point if the person eats 4 or more tablespoons of olive oil per day. Higher scores indicate a person’s greater adherence to the diet….
