‘Potassium-rich food helps reduce stroke in postmenopausal women’—PCRM

Data released by the Department of Health in 2013 cited that 25 percent of Filipino adults, or about 14 million, suffer from hypertension (high blood pressure), a major risk factor for heart disease and stroke.

Heart disease and stroke remain two of the top killers of Filipinos and comprise 35 percent of total deaths.

Philippine Health Statistics data show that in 2009 about 167,000 Filipinos died from heart disease and stroke. Half of these deaths were likely related to high blood pressure. An analysis done by the Philippine Institute for Development Studies (PIDS) further reveals that 34 percent of all cardiovascular deaths are happening prematurely or at ages below 60.

Means of prevention

Though the statistical realities of hypertension, stroke and heart disease have been divulged at length, little has been actually discussed on diet as a means of prevention, much less the potentials of a mineral such as potassium in significantly reducing the risk of stroke.

A recent Physicians Committee for Responsible Medicine’s Sept. 5 Breaking Medical News noted that a diet rich in potassium reduces the risk of stroke for postmenopausal women. It shared a study published online in the American Heart Association journal Stroke.

Reduction in risk

PCRM noted that researchers analyzed the potassium intake of 90,137 postmenopausal women as part of the Women’s Health Initiative Observational Study. Women who consumed the most potassium reduced their risk of all stroke types by 12 percent and lowered their risk of ischemic stroke (stroke due to clot formation) by 16 percent, compared with those who consumed the least amount.

PCRM noted that “the reduction in risk was even greater among women who had normal blood pressure, compared with those who had high blood pressure. High potassium intake was also associated with a reduced risk from death by all causes, compared with the lowest intake, during the 11 years of follow up.”

“This study suggests that all women should consume more potassium from foods like sweet potatoes, bananas and white beans to meet or exceed daily recommendations,” it said.

Like PCRM, preventive healthcare expert Neil Nedley, MD, has long advocated for vegan food (devoid of all forms of animal products, including dairy products) and high potassium foods to help reduce blood pressure.

Nedley said: “There are many foods that can be freely eaten without concern about their sodium content,” he said in his book “Proof Positive,” where he cited food groups low in sodium such as fresh fruits, grains and cereals, unsalted nuts, vegetables and shredded wheat.

Double benefit

“Fruits provide a double benefit in that they are also high in potassium, which tends to reduce blood pressure even further. This is partially why a natural diet high in fruits, vegetables and grains is the answer to the blood pressure problem,” Nedley said, adding that, however, “any food that is low in sodium can be made high by shaking the salt dispenser over it.”

Foods high in calcium content can also significantly lower blood pressure. Green leafy vegetables are good sources of calcium. A report on the research at the American Heart Association in 1992 warned against taking large amounts of calcium supplements. “Instead,” said Prof. James Dwyer who reported on that research, “people should get calcium through their diets … green leafy vegetables are good sources of calcium.”

A common breakfast food, oatmeal, has been found to reduce blood pressure. In one study, 850 people were categorized for the amount of oatmeal they consumed. One bowl per day consumers had lower blood pressure and lower cholesterol.

Managing blood pressure

Nedley suggested the following for people who would want to manage their blood pressure:

• Avoid low fiber foods such as meat (pork, beef, chicken and other livestock products) and dairy products (cow’s milk, cheese).

• Eat plenty of fruits, vegetables, grains and unsalted nuts in moderation, and other low-sodium foods.

• Avoid foods such as dill pickles, cured ham, Chinese rice, bouillon and other high-sodium foods. Read the labels.

• Eliminate coffee, cola drinks and alcohol from the diet.

• Stop smoking.

• Give the salt shaker a rest.

• Bring your weight down to the recommended level for your height and build.

• Adopt an aerobic exercise routine, such as brisk walking.

• Learn to cope with stress.
