Eat pistachios for better eyes: How a handful of nuts can improve vision

While green leafy vegetables are good for eyes, the natural fat content in pistachios help the body to absorb lutein more effectively.

With age, eyesight starts to take a hit. However, a recent study explains how having a serving of pistachios on a daily basis can help improve vision and protect us from age-related vision problems. The study, led by Dr Tammy Scott, Tufts University, observed that adults with a diet inclusion of two ounces of pistachios daily for 12 weeks showed better improvements in eye health than the adults who consumed a regular diet.

The study focused on analysing special protective pigments in the retina, also known as macular pigments. These pigments act as internal sunglasses that help in filtering out the harmful blue light. It also helps in protecting the retina from age-related macular degeneration.

Results of the study

The study was conducted on 36 healthy adults between the ages of 40 and 70 with a diet consisting of low amounts of lutein-rich foods. The participants were divided into two groups – one group was asked to add two ounces of unsalted pistachios to their diet, while the other group continued having their normal diet.

After six weeks, it was observed that the group that consumed pistachios regularly showed significant improvement in their eye health with increased macular pigment levels, while the other control group showed no changes.
