Stainless steel with some basic seasoning every once in a while (oil, high heat, it’s easy to do) has done me well for a long time. I do keep a non stick around just for eggs though, hard to beat.
I really love eggs, but they’re really high in cholesterol. It’s better to skip them, sadly. I wouldn’t normally offer unsolicited advice like this, but this is a thread about optimizing for health/safety. If you’re going to avoid teflon, you should probably avoid eggs too.
1) Dietary (exogenous) cholesterol has been shown to have a lesser affect to the total cholesterol levels in the blood (70-80% of all the cholesterol in your body is produced by your body endogenously by your liver and other tissues).
2) Eggs are an affordable source of various fats and proteins that are essential to metabolic health.
3) There are a group of people who assert that correcting hypercholesterolemia is best done by understanding the root cause of the overproduction of endogenous cholesterol.
4) We are beginning to understand that not all cholesterol is the same, and that high total cholesterol alone isn't a sufficient biomarker for predicting heart disease. Advanced lipoprotein fractionation tests looking for the ratio of small dense LDL to normal LDL, and HDL cholesterol is a better test; small dense LDL is bad and is a biomarker for inflammation and artery calcification, which can lead to heart disease.
