Lawson is of Jewish heritage. Both of Lawson’s parents are Jewish and her upbringing was non-observant. Lawson is an atheist.[132][13][133]
All the Jews I know eat pork. And if you see a cook on the Food Channel who is Jewish, they all seem to cook and eat pork. My wife and I once had breakfast with the owner of the company where I work. He and his wife and son are Jewish, and they all had bacon.
