One 12 ounce bottle of soda contains about 40 grams of fructose, one of the leading high blood pressure risk factors in North America. Consuming 74 or more grams of fructose per day increases your risk of high blood pressure by 77 percent. For people who are accustomed to drinking a can or two of soda daily, cutting the pop can have a dramatic effect on blood pressure, even eliminating the problem altogether.
Track your sodium levels. Many American diets include up to 5000 milligrams (5g) of sodium daily, which nearly all medical professionals consider extremely unhealthy. While you usually can't, and don't want to, cut out all sodium, it's important to try to get to below 2 g (2000 mg) per day. To do this, track your total daily intake of salt/sodium, and make sure you are avoiding as much sodium as you can.[5]
Magnesium: Magnesium, which is present in nuts, seeds, avocado, and green leafy vegetables, has also been proposed as a natural way to reduce blood pressure. Supplements are also available in pill form. Studies show that higher levels of magnesium are associated with lower blood pressure, but it is still not completely clear whether there is a cause-and-effect relationship. 
1. Isometric handgrip exercises. An American Heart Association study found that squeezing a spring-loaded handgrip for two minutes, over a period of 12 to 15 minutes three times a week, can help lower blood pressure. Why? The study found that blood flow returns to your hands after the isometric exercise, improving blood vessel function. Another study reported in the journal Hypertension found this exercise produced a 10% drop in both systolic (top number) and diastolic (bottom number) readings when practiced six times a day, five days a week for four weeks.
