I usually practice great hygiene (I won't go a few minutes without washing or sanitizing), and I like to take Vitamin C. Yeah, the part about eating is totally untrue, since my family loves eating out a lot and we do all the time in Winter (we've never even gotten a stomach ache from anytime that we've eaten out) In fact, the one and only time that my mom got true fp* was when she was cooking bad chicken (it was completely her mistake). So, eat out all you want! Just sanitize/wash your hands before you eat. Have a great Winter!
