Several food items in this mod give level two versions of their status effects instead of level one effects. Most of these effects are ones that do not change with effect levels, so giving level two versions of them is inconsistent both with vanilla and with other mods, and makes your mod look visibly buggy when I see, for example, Fire Resistance II on my inventory screen after eating a lily chicken plate. Comfort, Nourishment, Glowing, Nausea and Fire Resistance are the effects in question.
Looking at your source code, it seems like you tried to set the amplifier for these effects to 1 to get a level one effect, but this actually gives a level two effect. Setting amplifier to 0 yields a level one effect.
In addition, the food items with the above erroneous effects also have level II versions of all of their other effects that do scale with levels, as if you made the same mistake for all of the effects on those food items.

Looking at your source code, here are all of the affected food items:
[Glow Stew] Comfort II for 1200, Glowing II for 200
[Glow Venison Rib with Pasta] Nourishment II for 6000, Glowing II for 200
[Thousand Plant Stew] Nausea II for 300, Health Boost II for 600
[Grilled Ghast] Nourishment II for 6000
[Plate of Lily Chicken] Fire Resistance II for 6000, Nourishment II for 6000
[Plate of Fiery Snakes] Nourishment II for 12000, Comfort II for 6000, Strength II for 6000, Regeneration II for 400
[Thorn Rose Tea] Regeneration II for 100
[Twilight Spring] Resistance II for 600
