(No, not in-game, AFAIK)
Ok, so this sent me digging through the game data about food health… And I’m outraged by my findings.
First of all, in-game vitamin pills don’t make you healthier. Their health effect is ZERO. Eating them is useless, which is kind of funny, because that’s how it really is IRL. AFAIK the majority of vitamin supplements are entirely pointless, sometimes even harmful. I said it’s “kind of funny” but I’m not laughing - I’ve been munching vitamins myself in the game religiously. Something will be punched for this outrage… but not before my character gets super healthy.
Moving on. It turns out the majority of consumables have health values of 0, -1, or +1. Quite many of the food items have a health value of 0. I saw some -2s (most hard liqour), and some +2s (orange juice, some berries/fruit/veggies, chicken noodle soup). Cheap wine was -4, atomic energy drink had -6, sewage sample -20. Yikes. Mutagens get -2 or worse.
Pine tea, pineapples and pears net you +3.
Banana, cranberry and protein shake net you +4
Purifier (!), blackberry and grapefruit net you +5
Royal jelly and royal beef: +10
At that point I stopped doing searches. In no way is that list complete. You can view the values yourself in \data\json\items, in the file called comestibles.json, which can be viewed with a text editor. Look for the line “healthy”: for each item. At least I ASSUME that’s the health value.
The most important nutrient of adult human diet, beer, was given the value 0 (some beers get -1). I could be outraged by this but I don’t personally blame anyone because the increased health effect of beer comes through its positive psychological effect, which is enjoyed only by enlightened individuals who can truly value the bubbly dark golden nectar of the gods wholeheartedly and with their entire being. Mind over matter, and beer over mind.
So, understanding that the majority is 0, -1, or +1, it’s impossible to tell what has caused your unhealthy status. I’d suggest looking at what you’ve been eating and drinking mostly. Most of what you eat probably nets you 0 or -1 healthiness per portion. Especially look at the stuff that you can eat by the dozens in one sitting.
