I would imagine that it is a little bit harder to keep the grains and sugars low for vegans, but your triglycerides are likely the telling factor. Carbohydrate-rich diets can raise your trigs - even if you are eating whole grains, which are not probably as healthy as we are led to believe - especially in for certain groups of people. And there are a small population of people than can eat whatever the heck they want, never have any negative medical issues, and never gain any weight. Life is funny that way and hardly seems fair. If you are amenable to making some small dietary tweaks, I think you may see a lowering of your trigs and your cholesterol numbers as well. Maybe ask your doc for a 3 month extension, make some tweaks and then repeat your cholesterol/trigs test to see what happens.

If Janie sees this thread, hopefully she can chime in with her personal experience. I know that she was using a blood glucose monitor to see how different foods/meal types were impacting her glucose levels. I think that it was very helpful when she was crafting her diet.
