LONDON, Aug. 23 (UPI) -- A U.S. study purports women are better grocery shoppers than men because evolution has honed their ability to find nourishing food.

The report by researchers from the University of California, Santa Barbara and Yale University, published in Britain's Proceedings of the Royal Society: Biological Sciences, said women call on their navigational skills when there is food to be found -- a skill probably honed on the African savanna, The Telegraph reported Wednesday.

Experiments conducted at a large farmers’ market suggest the more nutritious the food, the more accurately it is remembered.

Researchers said memory for high-calorie foods such as honey and avocados was as much as four times as accurate as memory for low-calorie foods such as cucumber and lettuce, the British newspaper reported.
