Maja Zayeri covers heart health and cardiovascular risk for HealthCoachJP, including blood pressure, cholesterol, sodium and prevention. She works from AHA, CDC and NHLBI guidance and cites the source behind every number, including the sodium limits used across the site's nutrition pages. She is a health writer, not a cardiologist, and nothing she writes should be used to start, stop or change treatment. Talk to your doctor first.
