How Can You Prevent High Blood Pressure?

May is National High Blood Pressure Education Month

Everyone--regardless of race, age, sex, or heredity--can help lower their chance of developing high blood pressure. Here's how:

Maintain a healthy weight, lose weight if you are overweight,
Be more physically active,
Choose foods lower in salt and sodium, and
If you drink alcoholic beverages, do so in moderation.

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.

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 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. See the table below for low fat foods that you can enjoy instead.

TRY THESE LOW FAT FOODS

Baked, broiled or poached: chicken and turkey (without the skin); fish; lean cuts of meat (like round or sirloin).
Skim, 1%, or evaporated skim milk and lower-fat, low-sodium cheeses.
Fresh, frozen, or canned fruit.
Fresh, frozen, or canned (no salt added) vegetables (without cream or cheese sauces).
Plain rice and pasta, English muffins, bagels, sandwich breads and rolls, and soft tortillas.
Cold (ready-to-eat) cereals, lower in sodium and cooked hot cereals (not instant since they are higher in sodium).

Note: When choosing cheeses, breads, and cereals, use the food label to choose those lower in fat and sodium.

Choose foods high in starch and fiber. Foods high in starch and fiber, like those shown in the table, 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. 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.

2) Be more physically active.

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.

BE MORE ACTIVE EVERYDAY

Use the stairs instead of the elevator.
Get off the bus one or two stops early and walk the rest of the way.
Park farther away from the store or office.
Ride a bike.
Work in the yard or garden.
Go dancing.

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.

3) Choose Foods Lower in Salt and Sodium.

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:

Check food labels for the amount of sodium in foods. Choose those lower in sodium most of the time. Look for products that say "sodium free," "very low sodium," "low sodium," "light in sodium," "reduced or less sodium," or "unsalted," especially on cans, boxes, bottles, and bags.

Buy fresh, plain frozen, or canned with "no salt added" vegetables. Use fresh poultry, fish and lean meat, rather than canned or processed types.

Use herbs, spices, and salt-free seasoning blends in cooking and at the table instead of salt.

Cook rice, pasta, and hot cereals without salt. Cut back on instant or flavored rice, pasta, and cereal mixes because they usually have added salt.

Choose "convenience" foods that are lower in sodium. Cut back on frozen dinners, mixed dishes like pizza, packaged mixes, canned soups or broths, and salad dressings which often have a lot of sodium.

When available, buy low-or reduced-sodium, or "no-salt-added" versions of foods like these:

Canned soup, dried soup mixes, bouillon
Canned vegetables and vegetable juices
Cheeses, lower in fat
Margarine
Condiments like catsup, soy sauce
Crackers and baked goods
Processed lean meats
Snack foods like chips, pretzels, nuts

Rinse canned foods like tuna to remove some sodium.

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,

5 ounces of wine, or

12 ounces of beer (regular or light).

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.
