This datapack rewards players who eat different types of food. It also adds small bonus effects on certain foods.

The complete meal: I have divided almost all the food into 3 categories:
1) Meats and fishs (they must be cooked)
2) Fruits and vegetables
3) Starchy foods : Bread, Potato, cookies and cake

A player who eats at least one type of each food during his adventure is rewarded with a
passive effect that slightly raises his hunger bar for 16 minutes!

( A total of 11 food points are given to him over the duration )
A green particle effect appears on the cursor when the player gets this buff.
After that, the player can get this bonus again if he continues to eat varied food. The buff is'nt cumulative, its duration is simply reset.

The buff is not overpowering, but its duration of 16 minutes is interesting. So it is not necessary to eat a variety of foods, but it becomes much more valuable this way.

Digestion : When a player has a full hp bar, he still regenerates his hearts but gains the hunger malus and will fall back to 9.5 of food
(yes, this is a good Nerf to the saturation in vannila minecraft )

Special effects :
Some foods gain some peculiarities, like honey which removes the poisonous effect:
- Carrot removes a blinding effect
- The golden carrot provides immunity to blindness for one minute
- Dried kelp removes a slowing effect (and is eaten very quickly)
- Cooked salmon : immune to slowness for one minute.
- Porkchop immunizes against the effect of hunger
- Cookies give a small bonus of 20% speed for 6 seconds
- Mushroom soup confers immunity to fire for 6 seconds
- The beetroot gives a regeneration of 1 hp (1 half-heart)
- beetroot soup gives a regeneration of 1 hp and removes the wither effect.
- Rabbit stew consists of a meat, a vegetable and a starchy substance, it counts alone as a complete meal

(Pumpkin pie are made from a food source that is easily obtained from 100% automated farms, so it does not count to have complete meal. )

This datapack makes it globally easier for players to survive, to compensate a bit, having your hunger bar completely emptied applies a 15% speed malus on top of the usual HP loss.
