How can I trust a doctor like Ornish who doesn't admit that a low or better no fat diet is unhealthy, even more when studies and researches demonstrate that the countries with the lowest heart disease are France and Italy? The Mediterranean diet has a normal percentage of healthy fats, like the ones in olive oil and fish.What does he say about fish? "You might say, well, why not eat fish, because then you can get the fish oil directly from the fish. And you can. The problem is that the fish with the highest amount of omega 3 fatty acids are also the highest in fat and cholesterol"....so.....his answer is to take pills instead of eating healthy fish 3 times a week with a big salad!!! And I can't understand how a doctor like Oz who suggests to eat fish for Omega 3 had decided to collaborate with somebody suggesting exactly the opposite.
