There is absolutely no reason to fear saturated fat. That myth is dead. Well, it is dying, and it'll die hard and slow. Polyunsaturated fats, consumed in large quantities today, are another story. I will never knowingly touch another 'vegetable oil' - corn, soy, rapeseed/canola, safflower, sunflower, cottonseed, and haven't for over two years. The fruit oils - avocado, coconut and olive - are not so bad. Be sure to find olive oil that is not adulterated, cut with cheaper oils. I'd suggest California olive oils. But if you can get by with no processed oils - do it. Just eat natural fats - eggs, butter, cheeses, meats, fatty fish, cream - like folks did back when (pre-1920 or so) heart disease was a rarity, obesity was not epidemic, type II diabetes was not rampant. Cut three things out of your diet - processed oils, sugars/starches and grains (this would preclude you from eating any processed foods whatsoever) - and you'll be on the road to improved health. Very simple. But not easy. I went cold-turkey on the evening of March 7, 2019, cleared out the fridge and pantry, threw away several hundred dollars worth of groceries, started fresh. Cutting that stuff out is a challenge, because it is everywhere in everything and some of it is rather addictive. When you do cut it out, you'll be left eating meats, fish, eggs, greens, cheeses, high-fat dairy, a few nuts, berries... It is not a diet - you eat all you want, to satiety, with no intentional calorie restriction - just a different way of eating. An antiquated way of eating. A completely natural way of eating. Delicious, satisfying foods, but a big and fundamental change. But don't take my word for it. Youtube is a tremendously valuable resource, and there are plenty of free-thinking and bright physicians and researchers from around the world sharing valuable info there for your consideration.
