Salt added in cooking often makes foods tougher and the taste is mostly lost. When added in very small amounts is can impart a salty flavor - but in larger amounts is can be very sour. Most health food stores carry Bragg's Liquid Aminos, a product made entirely from soy beans. It has a very salty soy sauce flavor, but has much less sodium. For soy sauce, shoyu or tamari, always use the salt- reduced versions.
Caffeine is one of the world's most popular drugs.
It is believed to be harmful to those who already have heart disease and many other health problems, but the link has not been fully evaluated. Caffeine can shorten reaction time, keep one awake temporarily and give the feeling of increased energy. As with many drugs, the body can begin to build a tolerance to caffeine. This means that a person may need increasing amounts to get the same effects. As the dosage increases, trembling, muscle tension, irritability, nervousness, depression, disorientation, lethargy and throbbing headaches can result.
