Keeping blood pressure in check can help adults over the age of 60 live longer and healthier, according to a large, long-term study done by well-known Cochrane researchers.

Researchers involved with the study say that hypertension was previously regarded as a natural part of aging and that some health care providers were fearful of treating it.

"There are data on people under 60 that treatment of hypertension is effective and when properly utilized reduces the rate of stroke, heart attack and death. The majority of cases of hypertension, and especially new cases, are probably being diagnosed in those over 60," said Dr. Scott Wright, a professor of medicine with the Mayo Clinic.

Researchers say treating high blood pressure in the elderly can reduce deaths due to stroke as well as myocardial infarction or sudden cardiac death.

According to the Mayo Clinic, lifestyle changes can help prevent and treat hypertension at any age. They include maintaining a healthy weight, eating a proper diet, reducing stress and decreasing salt intake.

Among the nutritional supplements believed to decrease blood pressure are alpha-linolenic acid (ALA), blond psyllium, calcium, cocoa, cod liver oil, coenzyme Q-10, omega-3 fatty acids and garlic.
