I'm concerned about a friend of mine, age 60, who was told she was becoming diabetic and went on a vegan diet. For awhile, the diet was working to get her blood sugar and triglyceride levels in the near-normal range, then it stopped working. She was following the vegan diet religiously, though I know she would have things like coconut (which has high levels of saturated fats). Anyone else experience this? I think she is on some cholestero-lowering drug(s). Would it help more if she avoided almost all saturated fats, including palm oil and coconut?
