Rule changes around food.

Food has always been a easily passed over part of most role playing systems with exception of those where it is a tightly controlled survival resource. The goal is not to turn D&D into a survival game but to provide benefits for role playing and to alleviate some of the early game lack of options when magic is rare.

The basic premise is that an adventurer can have a meal effect and an extra effect active at a time, both last until the next meal, until they have a long rest, or if the effect is expendable. These can range from attribute save advantage to bonus health regained when healed. The game will still play fine without taking advantage of the Meal system, but it is designed to add little advantages to those who plan ahead.
