Low-fat diet with lots of fruits, veggies, and grains

CONCLUSIONS: Over a mean of 8.1 years, a dietary intervention that reduced total fat intake and increased intakes of vegetables, fruits, and grains did not significantly reduce the risk of [Coronary Heart Disease], stroke, or [Cardio-Vascular Disease] in postmenopausal women and achieved only modest effects on CVD risk factors, suggesting that more focused diet and lifestyle interventions may be needed to improve risk factors and reduce CVD risk.

"More focused"?  What does that mean?  Shouldn't they recognize that this approach simply does not work? 

Trying the same thing repeatedly and expecting a different outcome is a definition of insanity...
