I’m 84 and when I was 62, I was told that my cholesterol levels would kill me in a few years.
My RN wife and superb home chef/cook got me off the, then recommended high carb diets and focused on basically copying the Mediterranean diet.
Interestingly, I only recently tried extra virgin olive oil in place of butter on eggs and select veggies I always enjoyed with butter, and it tastes really good!
So we are using less butter, and I'm enjoying the new flavors.
