I probably wouldn't wash the pills down with your SHFV smoothies just in case as there are probably a lot of sugars and acids in them. Sof/Led and also Sof/Dac can be taken with or without food depending on preference. If you have either with food I would suggest a light, reasonably bland meal to get them absorbed into your bloodstream as quickly as possible. I take my Sof/Dac with a couple of sips of water in the morning then go for a 45 min walk to the shop to pick up milk and paper. So when I sit down to breakfast the drugs are pretty much absorbed already. But some find they need to have them with a bit of food.
You may want to have a look in the Experts Corner area of the site where there is a bit of info about vegetarian diets etc if you are on one.
However, I should warn that many of us find that once on treatment our careful, healthy diets go out the window! We can't help ourselves and start eating things we haven't had for years. I suspect part of this is that our bodies go into repair mode and we need extra protein and healthy fats to support that. Listen to your body and give it what it wants in moderation.....seems like a reasonable excuse to me?
