Rita, thank you for posting this. Really interesting topic. Excellent interview with lots of good, practical information. The discussion of why you need salt and how much to use is important to understand especially when you consider how it works synergistically with other minerals.
Dr. Hyman mentioned he had several different kinds of salt in his pantry. I've used the Redmond Real Salt which is mined in Utah from an ancient sea and it is very good. Sometimes it is hard to find in stores. Himalayan (pink) and Hawaiian (red) salts are excellent as well. All of these unrefined natural salts add beneficial trace minerals to your diet and enhance the flavor of the food you are eating. Refined table salt is harsh in comparison and you can really taste the difference. The cost might be a bit more upfront, but this last a long time and your food tastes so much better you will never want to use the refined stuff again.
