Reduce Hypertension by Avoiding Salt and Salty Food:

You can reduce high blood pressure by seriously cutting down on salt and salty food. Especially if you would prefer to avoid taking drugs, then I do urge you to cut down on salt/sodium and salty food. - And I don't just mean sprinkle less onto your meal or use less in cooking; I mean try to eat fresh food, instead of processed food, takeaways and ready meals, because these processed foodstuffs have usually had a lot of salt added to them by the manufacturers. If you feel you have to buy some processed food, then look carefully at the labels to choose a pack/tin with lower salt/sodium level.
