Vanilla extract, despite it having alcohol, won’t set you back too much. However, if possible use raw vanilla bean; its much stronger and doesn’t contain alcohol.
Stay away from all milk; almond milk may be a good alternative as well as hemp milk. Don’t drink soy milk because soy isn’t allowed.
If possible switch to greek yogurt and don’t have regular yogurt. I am unsure why greek yogurt is better, but I think its health benefits outweigh the consequences. I also think it may have a more pure form of milk in it. I am sorta curious about why greek yogurt is better!?
