There are probably some benefits to chicken soup that our grandmothers knew about. It also works well when promoting a series of self-help books. Trying to extrapolate these qualities to hypertension seems like a stretch to me. The USA Today came out with this headline:"Chicken soup may lower blood pressure, study finds" but the study has NOTHING to do with chicken soup. Instead, researchers in the Journal of Agricultural and Food Chemistry found that when they fed certain chicken proteins to rats that replicated a human model of hypertension, there was a significant drop in blood pressure. No mention of chicken soup. And has anyone ever eaten chicken soup without the salt? You would need to in order to negate the salt's innate quality to raise blood pressure. I think the biggest question that needs to be answered is why are rats eating chicken anyway? I never thought of them as big carnivores. You learn something new every day.
