How do we taste sweetness?
Sweetness comes from special molecules, like sugar, that fit into sweet taste receptors on our tongue. These receptors send a message to our brain saying, “This is sweet!” Foods like candy, fruit, and honey are sweet because they contain natural or added sugars. Even some plants, like stevia, can taste sweet without sugar because their molecules still trigger those same sweet receptors. Sweet tastes often tell our brain that a food contains energy.
How do we taste sourness?
Sourness happens when something has acids in it, like lemons, vinegar, or certain berries. Acids release hydrogen ions, and these tiny charged particles interact with sour taste receptors on our tongue. The stronger the acid, the more sour the taste. Sourness often warns us that a food is unripe or spoiled, but in small amounts, it can be refreshing and enjoyable, like a cool glass of lemonade on a hot day.
