7. Garlic and herbs
Like beetroot, garlic contains nitric oxide that helps promote widening of the arteries, otherwise known as vasodilatation. This can bring down blood pressure, and make food more flavorful to boot. Certain herbs are known to benefit hypertension as well.
Basil, cinnamon, cardamom, ginger, and celery seed are all great examples. Introducing more herbs and spices into your diet can also help to reduce the amount of sodium you need to enjoy meals.
