Pistachios take over carrots as ultimate weapon for better, sharper vision?

Carrots are often hailed as a superfood for eye health, but not everyone enjoys eating them. Fortunately, scientists have identified a nutty alternative for sharper vision: pistachios.

Researchers at Tufts University in Massachusetts, United States, found that consuming just two ounces, or 57 grammes, of pistachios daily can significantly support eye health.

These nuts are rich in an antioxidant called lutein that can boost "macular pigment optical density" (MPOD). Increased MPOD filters harmful light from screens, protects the retina, and helps combat degeneration, Daily Express reported.

Figures from the Macular Society show almost 1.5 million people in the United Kingdom are affected by macular disease, making it the nation's biggest cause of sight loss.

Dr Tammy Scott, a neuropsychologist who led the research, said: "Our study shows that pistachios aren't just a tasty snack — they may be great for your eyes.

"Eating a small amount every day can help protect your vision, especially as you get older."

According to the Daily Express, during the trial for the study, adults who were healthy except for a low lutein intake were asked to eat two ounces of pistachios a day, doubling their intake of the antioxidant.

This group saw a significant increase in their MPOD in just six weeks.

Dr Scott said: "Pistachios are a nutrient-dense snack providing essential vitamins, minerals and antioxidants."

Although lutein is available in other foods, such as broccoli and leafy greens, the pistachio's natural fats allow the antioxidant to be absorbed into the blood more easily.

The research, part-funded by American Pistachio Growers and the National Institutes of Health, was published in The Journal of Nutrition.
