@lindisfel My diet is hugely dairy and it's not hurting me.
My old numbers for decades when I didn't exercise:
total 6.6, LDL 4.4, HDL 1.8, TG 1.1; BMI 19.5
Now that I exercise:
5.2-5.7, 2.5, 2.5, 1.0; 20.0
The old concern with LDL total lipoprotein was misplaced. Certainly, when health indicators (BMI, blood pressure, etc.) are good overall, then LDL of 3.0 and total of 6.0 are OK.
I eat yogurt with fruit, high fat cheeses (eg cheddar), ice cream, cottage cheese, sour cream, some meat, fruit. No milk. Being lactose intolerant, I need lactase tablets for the cottage cheese and ice cream. A portion of one tablet suffices. One $8 box lasts me many months. A minority of people who eat eggs will see large rises in HDL and LDL. The rise in HDL removes any cause for concern about the rise in LDL. I have avoided white flour products almost entirely since the distant past. I will eat a couple of cookies a week. I lost interest in spaghetti.
Omega 6's. I just read the package label and don't eat omega 6's, except I suppose for the cookies. Potato crisps are fried in sunflower, safflower, or canola oil. When I found out about omega 6 oils a couple of years ago, I was disappointed and I gave up potato crisps almost entirely. They were the only regular part of my diet that contained vegetable oils.
