I’ve had pretty significant health gains once I totally gave up dairy. I’m now in the process of eliminating all refined sugars and processed foods, which is a bit harder to do. The urges are very strong though. It’s fascinating to me how much we’re poisoning ourselves.
IIRC there is a consensus forming that small amounts of white cheese (Mediterranean style feta) is allegedly substantially better for you than other cheeses, regular milk or butter consumption. Perhaps someone with a medical background can weigh in.
