When you sweat, your body undergoes a series of processes that allow for the release of toxins and an increase in metabolism. Sweat is made up mostly of water but also contains minerals, urea, lactic acid, ammonia and sugar. Sweating is your bodies way of regulating its temperature.
There are two main kinds of tofu: silken and regular. Silken tofu, also called soft, silk or Japanese-style tofu has a softer consistency than regular tofu and will fall apart if not handled carefully.
Packaged tofu should feature expiration dates, which you can use as a guideline for how long of a shelf life it will have. Tofu varies in texture from soft to firm to extra-firm. Soft tofu has a smoother texture and is therefore better suited for salad dressings, sauces, and desserts.
