High blood pressure affects millions of people. According to the CDC up to a third of those who have it do not even know it. Once you do find out the problem you may need to make some changes.
Weight Issues : According to heart.org dropping is few as five to ten pounds could lower blood pressure. That's great, but losing weight is not easy without knowledge and change.
The best method I've found is to use a calorie calculator. Caleriesperhour.com has the best one I've ever seen. It helps calculate everything you eat (including fast food) and everything you do. At the end of the day if you've burned more than you've eaten you are on your way to weight loss.
What to Avoid : There are things that can cause blood pressure to go up no matter how much you weigh. Sodium and caffeine are two of the worst offenders. Cutting sodium intake to 1200 mgs or less can make a big difference. Getting rid of caffeine is also wise. If you do take in a lot of it, do not go cold turkey. The withdrawal head is not pleasant.
Enjoying Food : Over the last nine years I've been working out ways to have good food that does not threaten blood pressure levels. Increasing the use of herbs and spices is one route. Using unsalted stock (or better still, make your own) is good. Even if I have to start from scratch (read the label on canned tomato sauce or canned pasta sauce and you'll see why), it can be done, tasty and healthy.
Nutritionists : Not everyone has the time or inclining to do a lot of from scratch cooking. A nutritionist can help you through the minefield of prepackaged foods and easy to prepare meals that stay within your diet budget. Your doctor can refer you and some insurance plans cover it.
