When it comes to eye health, carrots are often the first food that comes to mind, thanks to their high vitamin A content. But a new study reveals that pistachios, a small and tasty nut, offer surprising benefits for eye health—potentially surpassing those of carrots. Pistachios are rich in lutein, an antioxidant from the carotenoid family that is crucial for protecting the retina and reducing the risk of age-related macular degeneration (AMD), a leading cause of vision loss.
The study, conducted at Tufts University, involved 36 participants aged 40–70 who were divided into two groups: half added about two handfuls of pistachios to their daily diet, while the others maintained their regular diet. After 12 weeks, results showed that the pistachio group had a significant increase in lutein levels and macular pigment in their eyes. These pigments act like internal “sunglasses,” protecting the retina from damage, especially from blue light.
The unique advantage of pistachios lies in their healthy fat content, which allows for more efficient lutein absorption in the body. While leafy greens like spinach provide higher amounts of lutein, the fat content in pistachios optimizes the absorption process, making them particularly beneficial for eye health. As a result, pistachios may serve as a great alternative or addition to traditional eye-supporting foods.
Dr. Tammy Scott, a neuropsychologist and the study’s lead researcher, explains: “These findings suggest that pistachios can be more than just a nutritious snack, but also an effective tool in maintaining healthy vision, especially among adults.” She notes that when a lutein-rich diet is maintained over time, the benefits accumulate and help reduce the risk of retinal damage.
Pistachios are therefore a valuable addition to the daily menu for anyone looking to support healthy vision, alongside a balanced diet and a healthy lifestyle.
