Meet your taste buds. You have about 10,000, mostly concentrated on the top of your tongue. They can detect five basic tastes: sweet, sour and salty, bitter plus the more recently recognised umami. Your taste buds play a key role in helping you enjoy or stay away from certain foods which can be a problem when it comes to very fatty, sugary or salty foods. We've all heard of the “sweet tooth”, but some people have a “salty tooth” tooth as well. In fact, studies show that people with high blood pressure tend to have a preference for saltier foods, which is concerning as high salt intake is a known risk factor for high blood pressure and stroke. You don't have to follow your tastebuds though! You can train them to help you eat more healthily. Here's how.
