Sodium nitrate in meat: Heart disease risk factor?

Answer Section

Sodium nitrate, a preservative that's used in some processed meats, such as bacon, jerky and luncheon meats, could increase your heart disease risk.

It's thought that sodium nitrate may damage your blood vessels, making your arteries more likely to harden and narrow, leading to heart disease. Nitrates may also affect the way your body uses sugar, making you more likely to develop diabetes.

And you already know that most processed meats are high in sodium and some are high in saturated fat, which can disrupt a heart-healthy diet.

If you eat meat, it's best to limit processed meat and instead choose lean, fresh meat and poultry, and keep serving sizes small. For greater heart health, consider going one step further and increasing the amount of seafood in your diet.
