As we age, our eyesight often declines. However, a study reveals that including pistachios in our daily diet can help improve vision and protect against age-related eye issues.
Led by Dr. Tammy Scott from Tufts University, the study found that adults who ate two ounces of pistachios daily for 12 weeks experienced greater improvements in eye health compared to those on a regular diet.
The study focused on analyzing 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.
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.
How pistachios help in improving eyesight
Pistachios are an important source of lutein, a beneficial compound that helps in the formation of macular pigments in the retina. Usually, green leafy vegetables are the go-to food source for lutein, pistachios offer a distinct advantage over the others. Pistachios contain a natural fat content that helps the body absorb lutein more effectively.
Dr. Tammy Scott, a research and clinical neuropsychologist and lead author of the study, in a media release, stated that as people age and face issues of vision impairment, it is important to consume pistachios daily for better eyes and vision.
