Eating lots of spinach, washed with orange juice, is said to help reduce the risk of early memory loss in men.
Those who mock the green leaves that gave the cartoon sailor Popeye super force, fell to 34 percent, says a study.
Orange drinking is also protected against "bad thinking skills," which reduces risk by up to 49 percent, according to a survey of 28,000 men over 20 years of Harvard University.
Leading researcher Dr. Changzheng Yuan said: "Our studies provide additional evidence that choosing diets may be important for maintaining brain health.
"One of the most important factors in this study is that we were able to investigate and track such a large group of men over 20 years."
Participants have eaten different quantities of leafy vegetables such as spinach, red and orange vegetables and fruits.
