Salting is a sub category of the drying method. The main difference here is that salt is added to products, mainly meat and fish, to draw out moisture. This lowers the bacteria content and makes food adaptable for later use. Adding salt to animal protein turns it a bit leathery.
Diseases and conditions that may cause edema include: 1  Congestive heart failure. 2  When one or both of your heart's lower chambers lose their ability to pump blood effectively â as happens in congestive heart failure â the blood can back up in your legs, ankles and feet, causing edema.
For swollen ankles and feet caused by pregnancy, elevate your legs and avoid lying on your back to help improve blood flow and decrease swelling. If you have mild leg edema caused by venous insufficiency, elevate your legs periodically and wear support (compression) stockings.
