Salt may sound like a strange ingredient for a smoothie, a food that is usually sweet rather than savory. But, there are several good reasons to add a dash of salt to your next concoction, not least of which is flavor. Salt is a flavor-enhancer. A little bit makes any food taste better, even sweet foods.
The next reason is even better. If you choose the right salt you can add a nutritional boost to your smoothie. While typical, refined table salt is detrimental to your health, rock and sea salts can add important nutrients to your diet and actually improve your health.
