Do you do most of the shopping and cooking in your household? Do you eat many of your meals at home and do food preparation yourself, or do you bring in prepared foods? Johns Hopkins cardiologist Seth Martin says these are questions you need to ask yourself if you’re planning on substituting potassium chloride for sodium chloride in your diet to improve cardiovascular health.

Martin: I think we should talk a little bit about the total amount of salt and the sources it comes in, in our diets. Particularly here in the US and how this plays into that picture because the benefits here really seem to depend on using the salt substitute and the general way you would do that is in your food preservation or cooking. So you have to be someone who has some level of engagement in that for this to be relevant to you.  :27

Martin says choosing to eat at home more and cook food yourself can be a big win for your health all around. At Johns Hopkins, I’m Elizabeth Tracey.
