We don't sense acids in our food to make us look for sweet food. We sense acids because acidic food can damage our teeth, our mouths, our stomachs, etc (when eaten in excess). From the article: > "You can eat a berry and then bite into a lemon," says Harvey. "It becomes not only sweeter, but it will be the best lemon you've tasted in your life." If you eat a miracle berry and then snack on a whole bunch of lemon slices, they may not taste sour, but you will regret it in all kinds of ways. Also... miracle berry + lemon doesn't actually taste particularly good. There are "sweet lemons" and "sweet limes" (low acid varieties), and they're not popular because they're bland.
