ira byock and barbara coombs lee. thank you both. >> thank you. >> ifill: next, what makes food taste salty or bitter? what makes you want to eat more? scientists are trying to digest the secrets of flavor. hari sreenivasan has this report from minnesota. >> sreenivasan: when people go out to eat at restaurants like this neighborhood bistro in st. paul, they might be mindful of how much they're eating, or how much butter is used, or possibly calories. but most don't focus on a key component of the meal that they all share in common: salt. the center's for disease control say we eat twice as much salt as we should. three recent studies say that too much salt can lead to high blood pressure and heart disease. health officials recommend eating less, but consumers complain about the taste. enter professor devon peterson, an expert in food chemistry and analysis, he has made it his mission to revolutionize the processed food business by creating low salt products that taste good. to help with that goal he created the flavo
