Many people are afraid to use salt for fear of high blood pressure. It turns out a minority of people experience blood pressure issues directly due to salt consumption.
I am certainly not recommending eating processed foods with high salt content, but I do recommend using salt on your meats, fish and vegetables to assist your body with digestion, nutrient transport, and body function.
I recommend Sea Salt. It is not chemically treated & it contains many valuable trace minerals. Real Salt brand is widely available in groceries. Most table salt also contains dextrose (sugar) as a flavor additive after the valuable minerals are stripped away.
