According to new research from Tufts University, eating pistachios daily may serve as a preventative measure against blindness in old age. The study found that consuming two ounces of pistachios daily for 12 days significantly improved macular pigment optical density (MPOD), a crucial indicator of eye health. This discovery could be pivotal in reducing the risk of age-related macular degeneration (AMD), the leading cause of blindness among older adults.
Macular degeneration is a significant cause of vision loss for individuals over 60 years old. The study highlighted that pistachios, a nutrient-dense snack rich in essential vitamins, minerals, and antioxidants, correlated with a substantial increase in MPOD. Participants in the study experienced increased lutein levels after just six weeks, which doubled by the study’s conclusion. Lutein plays an essential role in protecting eyes from blue light damage and oxidative stress.
AMD exists in two forms: dry and wet. Dry macular degeneration is characterized by the formation of drusen deposits in the macula, leading to atrophy, while wet macular degeneration involves the accumulation of retinal metabolism byproducts that weaken a barrier preventing blood vessel growth into the retina. Although new medications are available for treating dry macular degeneration, they remain under evaluation in real-world settings.

The research underscores the potential benefits of pistachios as a dietary inclusion for maintaining eye health and preventing AMD. By improving MPOD health, pistachios offer a natural option that aligns with broader dietary approaches aimed at enhancing vision health.
