How
Can You Prevent High Blood Pressure?
Everyone--regardless
of race, age, sex, or heredity--can help lower their chance of
developing high blood pressure. Here's how:
1) Maintain a healthy weight, lose
weight if you are overweight,
2)
Be more physically active,
3)
Choose foods lower in salt and sodium, and
4)
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.
|
FOODS
HIGH IN STARCH AND/OR FIBER
|
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. Check the table below to see how many calories
you can burn during different activities.
