Lower Heart Attack Risk: Low-fat, high-fibre diet and exercise are key

UCLA scientists report that a diet low in fat and high in fruits, vegetables and whole grains, augmented with daily exercise, significantly reduced C-reactive protein levels in study participants. High levels of C-reactive protein (CRP) in the blood indicate inflammation in blood vessel walls.

Scientists now suspect that coronary artery inflammation plays a key role in making fatty deposits in the artery vulnerable to rupture, a leading cause of heart attacks. In fact, high CRP levels may be a better predictor of heart attacks than cholesterol levels, according to new research.

In the new study, the UCLA team, lead by Dr James Barnard, measured β€œentry and exit” blood values of 20 women, ages 51 to 79 years, attending a two-week program at the Pritikin Longevity Center. All had multiple risk factors for heart disease, including obesity, hypertension and diabetes. The women exercised daily and ate a diet focused on high-fibre carbohydrates such as fruits, vegetables and whole grains. Their diet also included lean, calcium-rich foods and lean servings of seafood, poultry and red meat.

The researchers found that in just two weeks, CRP levels plunged, on average, 45%. There were also major reductions in LDL cholesterol (19%), total cholesterol (17%), insulin (26%), glucose (11%), and triglycerides (15%).

Concludes Dr. Barnard: β€œWe know that inflammation is a key problem, a leading cause of heart disease, and now we’re learning that diet and exercise plans like the Pritikin Program may be a safe, smart solution.”
