True, margarine was never a good option over butter. I've eaten eggs almost daily for decades, and daily since moving here. I just stay away from dairy besides cheese and yogurt, as I was, and likely am still , allergic to milk.I've eaten 4-5 times a day for 50 years, high carbs, and low fat. My blood pressure is always around 115-54 and pulse 58, Blood sugar 88 so it worked for me. Only problem was H Pylori I got living here which hurt my gut, which I'm still recovering from. Yes, who really knows? I just try to emulate the Blue Zone as much as I can here, and will totally when we move back to Texas, besides the pizza and burgers, BBQ and steaks. They aren't going to be tossed aside. I love sauerkraut but only found it on Lazada, Bavarian style, at $9 a bottle.
