Hey I found a site that has a pdf that addresses
sea salt: It's under item # 12 and says...
The USDA (US Dept of Ag Food Guide) recommends that people consume 2,300 mg (approx 1 tsp) of salt/day. That quantity is often exceeded by the mere presence of the bulk of industrial foods consumed each and every day in North America, including breads, pastas, and cheeses, all saturated with salt. That's why most doctors tell their patients to stay away from salt, generally speaking. With all that salt, you don't need to add more salt to your food.
The IP weight loss method has none of these industrial foods, and even if choices of the IP envelopes are salted, you need to add sea salt to your diet: (talks about how to use salt) to ensure that your body has all the sodium it needs to function properly.
Fun fact: Salt is called Sodium Chloride, now here's why our bodies need SODIUM: Sodium helps maintain the fluid in our blood cells and is used to transmit information in our nerves and muscles. It is also used in the uptake of certain nutrients from our small intestines. The body cannot make sodium and so we are reliant on food to ensure that we get the required intake.
CHLORIDE: Chloride, too, is essential to good health. It preserves acid-base balance in the body, aids potassium absorption, supplies the essence of digestive stomach acid, and enhances the ability of the blood to carry carbon dioxide from respiring tissues to the lungs.
