Does our body’s have to get used to digesting outside survival foods like chamomile flowers, plantain, clovers, ect. ?

You do need to get used to eating a lot of raw food especially mustards in my case. Even raw broccoli causes me quite a lot of pain. There is toxin in even cabbage that is dangerous if you eat enough raw. Apparently I have some pain nerves in my stomach sensitive to that toxin. I could probably get used to even that if I had to but it is a good idea to start eating some new food very slowly until you see how it affects you. Some raw vegetables feel great in the stomach like lettuce, minors lettuce and purslane and then there are others that need to be cooked or not eaten. In survival situations you probably don't want to try to eat a lot of some food you aren't used to. It is liable to make you feel nauseous or worse. Clean water is far more important. It would be very hard to get enough calories unless you were a skillful hunter and probably not fussy about what you eat. As pot herbs, sow thistles don't bother me. I could eat as much of them as I pleased. Plantain is kind of hard to eat more than a handful and the same with clovers. Sweat clovers and probably some other clovers can be toxic by the way. It might be some fungus that makes sweat clover hay dangerous. I just remember something makes me cautious about clovers. I do like the look alikes, the oxalis or sorrels. Some of them taste wonderful. You have to be careful an not eat much of them or eat them often because of oxalic acid that makes them tangy. Many of the wild foods have mild but potentially dangerous toxins that prevent them from being more popular. With dandelions it just makes them really bitter as far as I know. Most others start to have some serious side effects if you eat a whole lot of them. Our bodies are better suited to removing small amounts of toxins from various plants. It is why chimps eat a few hundred types of plants. No one plants toxins are going to rise to significant levels if you vary the diet. The point is the natural diet would be eating hundreds of wild foods. A person new to the environment would concentrate on single species and would be more likely to have toxic reaction especially raw plants. I think it would take a long time to get used to most survival foods. Your body would probably be fine digesting the food. It might take you a while to find wild food that is feels good in the stomach or how to prepare them.

You aren't used to eating any plant types found in the outdoors, so you would need to know what you are eating. Some poisonous plants looks very similar to other plants, and there isn't much nutritional value in eating most wild growing plants. No fats, proteins, etc. in most plants like you named. That's why plant eating animals need to eat copious amounts of plants evert day. Mushrooms ( in season ), can be especially dangerous because it's difficult to tell a safe mushroom from a poisonous mushroom unless you know what you're doing. So do a lot of studying and seek the assistance of someone who is "at home" in the outdoors as far as "living off of the land". You can learn how to use various plants to stay alive, and how to use plants to supplement your daily nutritional needs in a survival situation. You won't be able to survive for an extended time outdoors, unless you can supplement the plants you can get, with some type of meat or fish as well.

Yes it does your body is not going to like eating survival Foods at first but I want to bring to your attention that you can always do what a cow does you can take safe green things put it in a big container and ferment it well and strain out the vegetation matter and warm it up enough to drive off the alcohol alcohol provides no nutrition what you have left is a brew which is nourishing and taste like beer

No, our "body's doesn't".
