v Reduce sodium — The main source of sodium in the diet is the salt contained in
packaged and processed foods and in foods from restaurants. Reducing the amount
of sodium you consume can lower blood pressure if you have high or borderline
high blood pressure.
v The body requires a small amount of sodium in the diet. However,
most people consume more sodium than they need. A low-sodium diet contains
fewer than 2 grams (2,000 milligrams) of sodium each day.
v Reduce alcohol — Drinking an excessive amount of alcohol increases your risk of
developing high blood pressure. People who have more than two drinks per day
have an increased risk of high blood pressure compared to nondrinkers; the risk
is greatest when you drink more than five drinks per day.
v On the other hand, drinking one (for women) or two (for men)
alcoholic beverages per day appears to benefit the heart in people greater than
40 years old. This protective effect applies to people with preexisting high
blood pressure.
v Eat more fruits and vegetables — Eating a vegetarian diet may reduce high blood pressure and protect
against developing high blood pressure. A strict vegetarian diet may not be
necessary; eating more fruits and vegetables and low-fat dairy products may
also lower blood pressure.
v Eat more fiber — Eating an increased amount of fiber may decrease blood pressure. The
recommended amount of dietary fiber is 20 to 35 grams of fiber per day. Many
breakfast cereals are excellent sources of dietary fiber. More information
about increasing fiber is available separately.
v Eat more fish — Eating more fish may help to lower blood pressure, especially when
combined with weight loss.
v Caffeine — Caffeine may cause a
small rise in blood pressure, although this effect is usually temporary.
Drinking a moderate amount of caffeine (less than 2 cups of coffee per day)
does not increase the risk of high blood pressure in most people.
