I have mitral valve stenosis and take verapamil and warfarin. I have been looking for low sodium diet books in bookshops for ages, and just by accident came across your site - it's fantastic. I can say after a week of trying your recipes I feel a lot better. I also found that the chicken breast piece I bought from the supermarket had over 500mg of sodium - what is the daily RDA for an adult female? I had thought that chicken was a healthy alternative to beef and lamb - am I wrong?
We do often have our patients with issues such as your mitral valve stenosis on a low sodium diet. Most physicians recommend a 2,000 mg per day diet in such cases but check with your doctor regarding the level he or she wants you to be at.
I am not sure why the chicken breast you purchased was labelled that way. A 4 ounce chicken breast has about 73 mg of sodium in it naturally. Possibly the one that you chose was pre-prepared with seasonings that contained salt. Check the ingredients section on the package to see if there is added salt.
It is a great idea for you to be reading food labels like you are. Becoming more knowledgeable of the foods that you are eating and how much sodium they contain is really smart. If the ingredients don't list salt (or another sodium like sodium bicarbonate) then the sodium content is naturally occurring in the food.
