What’s the best meal to focus on with nutrition when starting running?

I’ve been struggling with a disease that has caused a lot of malnutrition in my life which has made sports very difficult for me (even though I love to move).
I’ve been out of the hospital for 4 years and I’m starting to regain my strength. I’ve started rock climbing and built up endurance on the elliptical but now I want to really get on the road and run. Recently, I went for a run on the treadmill and my legs went numb, they didn’t hurt but I was afraid to twist the wrong way. I had a recent check-up and my heart/blood flow is normal if not excellent but I’ve always struggled with proper nutrition because of my disease that makes me very ill. My doctor suggested taking multivitamins but I’d like to have some kind of diet to focus on (even if it’s one meal) without relying on popping pills.
My disease causes deficiencies in vitamin D(all), B12, calcium, magnesium, riboflavin, and sometimes fiber/iron/protein.
I also have to stay away from foods such as pork, kiwi, bananas, raw potatoes, avocados, chestnuts, tomatoes, carrots, apples, buckwheat, all wheat derivatives, walnuts, and castor beans.
I’ve taken nutrition before but most of my professors and doctors suggest taking pills because of how “difficult” my illness is to deal with and I can’t afford a nutrition.
Does anyone have any suggestions on books with exact recipes that accommodate this predicament or know of even one meal that can capture what I need accommodating what I can’t eat?
It seems that whenever I get close to a recipe, it involves ingredients I can’t eat.

Thank you!!

What is a decathlon?

Can you help me understand what a decathlon actually is? I’ve heard a lot about it from my friends, but I, myself really don’t know what it is. It would be a big help if you can give me an insight about it. Thanks in advance.
