Liking that 'salty taste' begins at birth

Are you a fan of salty foods? Most of us are I would suspect -- as sodium is in so many foods these days (and large amounts of it). But, why do we all crave sodium and salt so much?

A new study suggests that some people that are salt cravers may have been born with that in them. With high salt intake being considered a marker for the risk of obesity, reducing the overconsumption of it is probably a good dietary decision for many.
