Foods to Avoid If You Have High Blood Pressure

63. "Healthy" Protein Bars and Shakes: A Salt and Sugar Mix-up

You grab a protein bar for a quick energy boost, but these can be a hidden source of both salt and sugar. Many commercial protein bars and shakes use large amounts of sodium to improve flavor and preserve ingredients. Some bars contain over 400mg of sodium per serving, which can contribute to fluid retention and high blood pressure. Smart swap: Opt for whole-food sources of protein like nuts, Greek yogurt, or a piece of grilled chicken. If you must have a bar, look for brands with minimal ingredients and a low sodium and sugar count.

64. Licorice (The Adrenal Connection)

An extremely unique and often missed dietary contributor to hypertension is the regular consumption of natural black licorice. This isn't due to sodium, but a compound called glycyrrhizin found in the licorice root. Glycyrrhizin mimics the effects of aldosterone, a hormone produced by the adrenal glands that is responsible for regulating salt and water balance. By interfering with an enzyme that breaks down cortisol, it effectively increases mineralocorticoid activity. This leads to the retention of sodium and water while causing a loss of potassium, dramatically increasing blood volume and causing a significant, dose-dependent rise in blood pressure.
