Following is a list of some of the more important ions in the cells and fluids of our bodies: Sodium ions are the principal cations found outside cells in the body. They help regulate and control the level of body fluids. Too little leads to diarrhea, anxiety, a decrease in body fluids, and circulatory failure.
Texture-wise, macarons are a unique combination of crisp, soft, and chewy. They aren't supposed to crumble into mush, and they shouldn't be so hard that you're getting a bonafide jaw workout.
