VIT C MIX - dietary options

Hey All,
I'm glad this forum exists. Thanks in advance!
I'm on the Vit C treatment - about to do it tomorrow.
I normally eat meat, fish, fruit, and veggies - mostly if not all cooked. I don't eat processed food except for a gummy worm here and there. Seriously. My diet is very simple these days.
Can i eat boiled sweet potatoes during the Vit C 25 hours? Are there any other veggies that I can eat if they're well-cooked enough? I thought Vit C goes away when heated long enough... Let me know what you know. Thank you! Tweet
