Even if you don’t keep a salt shaker on the table, you may have too much sodium in your diet. Processed foods -- especially canned soups, salad dressings, snack mixes, and fast food -- are a large contributor of sodium to your diet. Read food labels and choose low-sodium options when possible. Aim to consume less than 2,300 milligrams per day, and less than 1,500 milligrams if you’ve already been diagnosed with hypertension.
You can lower your systolic blood pressure (the top number) by switching to the DASH diet. The DASH diet is based on 2,000 calories a day. It's rich in fruits, vegetables, and low-fat dairy products. It's also low in saturated fat, cholesterol, and total fat. According to studies, adopting a DASH diet can reduce systolic blood pressure by eight to 14 points. The goal is to keep you blood pressure goal is less than 120/80.  
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.
First, keep in mind that drugs have limited success. Most studies on diuretics and other blood pressure-lowering drugs suggest they lower the risk of cardiovascular events among those with blood pressure between 140/90 and 159/99 by 15 to 20%.3 The problem is, with this range of blood pressure, the risk of cardiovascular-related deaths has increased by 300 to 400% compared to people with normal blood pressure.
2. Take the right nutrients. Talk with your chiropractor or other healthcare professional about the wide range of well-studied nutrients that, along with dietary and lifestyle modifications, can help normalize your blood pressure. One meta-analysis found magnesium supplements could lower blood pressure. Likewise, researchers find a small but significant decline in blood pressure for people with hypertension who use fish oil.
