I prefer frozen foods to canned foods but we need to keep canned foods in case of emergency. If the electricity is off for a long time, the frozen foods will melt and spoil.
My hubby is on low salt diet, so I don't add salt to any food he eats. I can taste the too salty foods now that we have had to cut back on so much. He is on heart cardiac and diabetes diet, too.
I don't have high blood pressure or diabetes, but I have been mostly vegetarian since 1995.
