My dad (62) just had big heart attack in January. 100% blockage in a vein covering 60%+ of his heart. The surgeon who put his stent in called his EKG “impressive”. He’s never eaten very well or exercised much, and the Mediterranean diet was one of the ones they recommended. My mom (always reading health books) decided to go for an extreme no fat, no oil(!) diet instead, which is difficult in practice. His labs six weeks later showed a greater than 100pt drop in his cholesterol and 30lbs+ of weight loss. He’s able to come off of his previous blood pressure medication, is sleeping better than ever and adding distance to his daily mile walk. Anyway, if you or someone you know is at high risk, turnarounds are absolutely possible with diet, and it might be worth further examining oils and “good fats” if your body doesn’t process cholesterol well.
