Hard foods become soft when cooked because the heat breaks down the tough fibers and connective tissues, making them easier to chew and digest. On the other hand, soft foods can become hard when they are exposed to high heat or long cooking times, causing the moisture to evaporate and the sugars to caramelize, resulting in a firmer texture. The changes in texture that occur during cooking are due to the denaturation of proteins and the breakdown of starches and other molecules in the food. **

Testing out different options and finding the right balance of comfort and support is key to getting a good night's sleep. **
