The way educated women spend their time in the United States and other rich countries has changed radically over the past half a century. Women in the US now spend around 45 minutes per day in total on cooking and cleaning up; that is still much more than men, who spend just 15 minutes a day. But it is a vast shift from the four hours a day which was common in the 1960s. We know all this from time-use surveys conducted around the world. And we know the reasons for the shift. One of the most important of those is a radical change in the way food is prepared.
