How Can You Prevent High Blood Pressure?
These rules are also recommended for treating high blood pressure, although medicine is often added as part of the treatment. It is far better to keep your blood pressure from getting high in the first place. Another important measure for your health is to not smoke: while cigarette smoking is not directly related to high blood pressure, it increases your risk of heart attack and stroke. Click here for information on quitting smoking. Let's look more closely at the four rules to prevent high blood pressure and for keeping a healthy heart: 1. Maintain a healthy weight, lose weight if you are overweight. As your body weight increases, your blood pressure rises. In fact, being overweight can make you two to six times more likely to develop high blood pressure than if you are at your desirable weight. Keeping your weight in the desirable range is not only important to prevent high blood pressure but also for your overall health and well being. It's not just how much you weigh that's important: it also matters where your body stores extra fat. Your shape is inherited from your parents just like the color of your eyes or hair. Some people tend to gain weight around their belly; others, around the hips and thighs. "Apple-shaped" people who have a pot belly (that is, extra fat at the waist) appear to have higher health risks than "pear-shaped" people with heavy hips and thighs. No matter where the extra weight is, you can reduce your risk of high blood pressure by losing weight. Even small amounts of weight loss can make a big difference in helping to prevent high blood pressure. Losing weight, if you are overweight and already have high blood pressure, can also help lower your pressure. To lose weight, you need to eat fewer calories than you burn. But don't go on a crash diet to see how quickly you can lose those pounds. The healthiest and longest-lasting weight loss happens when you do it slowly, losing 1/2 to 1 pound a week. By cutting back by 500 calories a day by eating less and being more physically active, you can lose about 1 pound (which equals 3,500 calories) in a week. Losing weight and keeping it off involves a new way of eating and increasing physical activity for life. Here's how to eat and get on your way to a lower weight:
Choose foods high in starch and fiber. Foods high in starch and fiber are excellent substitutes for foods high in fat. They are lower in calories than foods high in fat. These foods are also good sources of vitamins and minerals. Eat more fruits, vegetables, whole-grain cereals, pasta and rice, whole-grain breads, dry peas and beans. Note: Use the food label to choose breads and cereals lower in sodium. Limit serving sizes. To lose weight, it's not just the type of foods you eat that's important, but also the amount. To take in fewer calories, you need to limit your portion sizes. Try especially to take smaller helpings of high calorie foods like high fat meats and cheeses. And try not to go back for seconds. Here's a good tip to help you control or change your eating habits: keep track of what you eat, when you eat, and why, by writing it down. Note whether you snack on high fat foods in front of the television, or if you skip breakfast and then eat a large lunch. Once you see your habits, you can set goals for yourself: cut back on TV snacks and, when you do snack, have fresh fruit, unsalted air-popped popcorn, or unsalted pretzels. If there's no time for breakfast at home, take a low fat muffin, bagel (skip the cream cheese), or cereal with you to eat at work. Changing your behavior will help you change your weight for the better. Increase physical activity. There's more to weight loss than just eating less. Another important ingredient is increasing physical activity, which burns calories. Cutting down on fat and calories combined with regular physical activity can help you lose more weight and keep it off longer than either way by itself.

2. Be More Physically Active. Besides losing weight, there are other reasons to be more active: being physically active can reduce your risk for heart disease, help lower your total cholesterol level and raise HDL-cholesterol (the "good" cholesterol that does not build up in the arteries), and help lower high blood pressure. And people who are physically active have a lower risk of getting high blood pressure - 20 to 50 percent lower - than people who are not active. You don't have to be a marathon runner to benefit from physical activity. Even light activities, if done daily, can help lower your risk of heart disease. So you can fit physical activity into your daily routine in small but important ways. More vigorous exercise has added benefits. It helps improve the fitness of the heart and lungs. And that in turn protects you more against heart disease. Activities like swimming, brisk walking, running, and jumping rope are called "aerobic." This means that the body uses oxygen to make the energy it needs for the activity. Aerobic activities can condition your heart and lungs if done at the right intensity for at least 30 minutes, three to four times a week. But if you don't have 30 minutes for a break, try to find two 15-minute periods or even three 10-minute periods. Try to do some type of aerobic activity in the course of a week. Most people don't need to see a doctor before they start exercising, since a gradual, sensible exercise program has few health risks. But if you have a health problem like high blood pressure; if you have pains or pressure in the chest or shoulder area; if you tend to feel dizzy or faint; if you get very breathless after a mild workout; or are middle-age or older and have not been active, and you are planning a vigorous exercise program, you should check with your doctor first. Otherwise, get out, get active, and get fit--and help prevent high blood pressure. Click here for HOOAH 4 Health Fitness Tools.
Americans eat more salt (sodium chloride) and other forms of sodium than they need. And guess what? They also have higher rates of high blood pressure than people in other countries who eat less salt. Often, if people with high blood pressure cut back on salt and sodium, their blood pressure falls. Cutting back on salt and sodium also prevents blood pressure from rising. Some people like African-Americans and the elderly are more affected by sodium than others. Since there's really no practical way to predict exactly who will be affected by sodium, it makes sense to limit intake of salt and sodium to help prevent high blood pressure. All Americans, especially people with high blood pressure, should eat no more than about 6 grams of salt a day, which equals about 2,400 milligrams of sodium. That's about 1 teaspoon of table salt. But remember to keep track of ALL salt eaten--including that in processed foods and added during cooking or at the table. Americans eat 4,000 to 6,000 milligrams of sodium a day, so most people need to cut back on salt and sodium. You can teach your taste buds to enjoy less salty foods. Here are a few tips:
4. If You Drink Alcoholic Beverages, Do So In Moderation. Drinking too much alcohol can raise your blood pressure. It may also lead to the development of high blood pressure. So to help prevent high blood pressure, if you drink alcohol, limit how much you drink to no more than 2 drinks a day. The "Dietary Guidelines for Americans" recommend that for overall health women should limit their alcohol to no more than 1 drink a day. This is what counts as a drink: 1-1/2 ounces of 80-proof or 1 ounce of 100-proof whiskey, You may have heard that some alcohol is good for your heart health. Some news reports suggest that people who consume a drink or two a day have lower blood pressure and live longer than those who consume excessive amounts of alcohol. Others note that wine raises the "good" blood cholesterol that prevents the build up of fats in the arteries. While these news stories may be correct they don't tell the whole story: too much alcohol contributes to a host of other health problems, such as motor vehicle accidents, diseases of the liver and pancreas, damage to the brain and heart, an increased risk of many cancers, and fetal alcohol syndrome. Alcohol is also high in calories. So you should limit how much you drink. What Else Might Prevent High Blood Pressure? Other things also may help prevent blood pressure. Here's a roundup of what's being said about them-and whether it's true or false.
Dietary Supplements--Potassium, Calcium, Magnesium, Fish Oils.
Calcium.
Magnesium.
Fish oils.
Other Factors Fats, Carbohydrates, and Protein. Varying the amount and type of fats, carbohydrates, and protein in the diet has little, if any, effect on blood pressure. But for overall heart health, it is crucial to limit the amount of fat in your diet, especially the saturated fat found in foods like fatty meats and whole milk dairy foods. Saturated fats raise your blood cholesterol level, and a high blood cholesterol level is another risk factor for heart disease. Foods high in fat are also high in calories. Remember, foods high in complex carbohydrate (starch and fiber) are low in fat and calories - so eating these foods in moderate amounts instead of high fat foods can help you to lose weight if you are overweight or to prevent you from gaining weight. Caffeine. The caffeine in drinks like coffee, tea, and sodas may cause blood pressure to go up, but only temporarily. In a short time your blood pressure will go back down. Unless you are sensitive to caffeine and your blood pressure does not go down, you do not have to limit caffeine to prevent developing high blood pressure. Garlic or Onions. Increased amount of garlic and onions have not been found to affect blood pressure. Of course, they are tasty substitutes for salty seasonings and can be used often. Stress Management. Stress can make blood pressure go up for a while and over time may contribute to the cause of high blood pressure. So it's natural to think that stress management techniques like biofeedback, meditation, and relaxation would help prevent high blood pressure. But this doesn't seem to be the case: the few studies that have looked at this have not shown that stress management helps to prevent high blood pressure. Of course, stress management techniques are helpful if they help you feel better or stick to a weight-loss and/or exercise program. Here's a Recap After going through all the things that may affect blood pressure, it's worth noting again the things that are sure to help you prevent high blood pressure:
By following these guidelines, you can help reduce or prevent high blood pressure for life--and, in turn, lower your risk for heart disease and stroke.

Everyone - regardless of race, age, sex, or heredity - can help lower their chance of developing high blood pressure. Here's how:
Choose foods low in calories and fat. Naturally, choosing low-calorie foods cuts calories. But did you know that choosing foods low in fat also cuts calories? Fat is a concentrated source of calories, so eating fewer fatty foods will reduce calorie intake. Some examples of fatty foods to cut down on are: butter, margarine, regular salad dressings, fatty meats, skin of poultry, whole milk dairy foods like cheese, fried foods, and many cookies, cakes, pastries and snacks.
3. Choose Foods Lower in Salt and Sodium.
