The American Heart Association recommends eating one to two servings, or 5.5 ounces, of protein daily
Eating a balanced diet including protein from a greater variety of sources may help adults lower the risk of developing high blood pressure, according to new research published in Hypertension, a peer-reviewed journal of the American Heart Association.
Nearly half of the US population has hypertension, or high blood pressure, one of the leading contributors to cardiovascular disease. When left untreated, high blood pressure damages the circulatory system and is a significant contributing factor to heart attack, stroke and other health conditions.
Participants were given a protein “variety score” based on the number of different sources of protein eaten out of 8 reported: whole grains, refined grains, processed red meat, unprocessed red meat, poultry, fish, egg and legumes. One point was given for each source of protein, with a maximum variety score of 8. The researchers then evaluated the association for new onset hypertension in relation to the protein variety score.
Compared to participants with the lowest variety score for protein intake (less than 2), those with the highest variety score (4 or higher) had a 66% lower risk of developing high blood pressure.
