If you think it is "trivial" to make a bland substance taste good without substantially changing the nutritional makeup of that substance, there are a lot of diet food companies who would like to have a chat with you and make you fabulously rich. Jamba Juice would like to know the secret, too.

Most things that innately taste good -- stuff that you could drop in a blender and drink and it'd still be agreeable -- are fatty, salty, starchy, sugary, or some mix of all these. Healthy and good-tasting food requires pleasant textures and careful composition that allows a small amount of fat, salt, starch, etc. to enhance the flavor of the whole meal.
