The winner of food abuse shall remain 1.7.10 berries until further notice.
* you can eat even when full, and fill your saturation abr
* The producing plant grows to make more producing plants, so once you get started you never run out
* While there is a "benefit" to having three of the 4 types, you get the real benefit from only one -- the berry medly bowl doesn't give you any benefit over just spamming one berry
All your food needs from a single inventory slot. Fill it up to 64 before you leave, and off you go. On the road, each berry heals two damage if you can hole up (one for the saturation boost, one for the main food), and another 20 or so for completeness will fill up the saturation bar so you don't even notice your food situation until you've gone through a lot more damage.
I don't think I've ever run out of food from a single inventory slot of the things while out exploring/caving/fighting.
How do they differ from watermelon slices (vanilla)? They can max out the saturation bar. With water melon, you keep filling up the main bar, run out of saturation, have to repeat. With these things? You can heal something like 1 and a 1/2 full health bars of damage before you need to eat, that's as good as a pair of steaks/porkchops.
