🍽️ Food Guide: Safe & Problematic Lists

🧠 Key Principles for Your Diet

Freshness is everything — Histamine and glutamate levels increase as food ages. Buy fresh, cook fresh, freeze leftovers immediately.
Isolate and test — Introduce new foods one at a time in small quantities to observe your reaction.
Avoid the "whammy" combination — Be especially careful not to combine multiple triggers (e.g., yogurt + beets + beet greens).
Trust your n=1 data — This list is a guide. Your body's feedback is the final authority.
