Why do my stomac reacts to green juice more than the whole plant?

I really eat a big plate of greens and colors every day, with fats in form of avocado emulsified with olive oil, seeds like pumkins or cañamo + cider vinegar.
I can make nice sauces with avocado, a sort of green mayonaise, that I can do with or without egg yolk.

I was juicing a little, and mixing the juice with the sauce.
Those who juice know how strong can be a green juice!
Sick...

Even with avocado etc, I cannot finish the amount I would eat readily without the juice.
Sick...
Stomac growling, bubbleling...
Then I have gone to mixing. That is thin, so easy to eat, and I put vinegar also.
Better but not satisfying.

And now I can eat happily what I thought harder to swallow: the whole stuff.
I just gather everything on the cutting board, and cut very thin with a knife.
I am almost sure I eat less, but I feel great, not sick as with the juice.

I know the problem of juicing fruits, because of sugar.
There is no such problem with veggies.
So what is the problem?
Does it happen to other persons?

I can feel this is a real physical reaction, and that my digestion is affected. If I could know why...

I know that people advise to go slowly for increasing intake of the green juice, or that they cover the strong tastes with celery, cucumber and even apple....
So I wander if the problem I feel comes from the juice form or from the strong taste.

I'm not sure I understand exactly what you were doing, and which things made you sick, but it sounds like maybe it's not good to be too extreme on eating greens and juices. I mean, greens are wonderful and I love them, but I don't think we should eat nothing but green veg. Maybe some people can do that and feel great, but if it makes you feel sick, maybe you're being too extreme... maybe you should reduce it and be more moderate and diverse in your food?

Or maybe I didn't understand what you were doing.

Hey Xisca,
Health practitioners generally advice using juices from the weaker greens to start. Celery, romaine, anything really watery. Stuff like Kale can even turn a frequent juicers stomach sour. Also. you mention much about combinations. Take juices on their own. What I often do is have some wheatgrass juice after some water in the mornings. Then I'll do some intense exercise and have a breakfast. Wheatgrass/barely grass are the best things to juice for numerous reasons. If you want more green stuff add spirulina by nutrex to your diet- you will be amazed. I usually use between 1/2 tbsp-3tbsp in a protein shake.
It is hard to over do it with greens. You are over doing it when things don't taste amazing anymore. We must remember the most common flavor in nature is bitter. Do you think the native were hopped up on sandwiches while tending to there land?
Let me know if you would like further advice.

To be more precise:
- I was doing little
I don't WANT greens, I have them and use them.
- I want to use what is growing on its own, not sprouting on purpose. When I sprout (buckwheat, I am gluten sensitive) I eat all.
- I do not drink nor eat fast, because this would be a difference with chewing a salad.

- The mix was especially with avocado
I can mix salad with avocado, meat, cheese, eggs, olive oil, sprouts...
So I should be able to mix the same with veggies juice, shouldn't I?

I just want to know what is the difference between liquid juice and the solid pre-crushed plant, or crushed in mouth with teeths...
I feel it is different and would like to know why.

Is it just a reaction to the taste? This is my best guess at the moment.
Is it the lack of fiber and the concentration?

It's definitely the combo and concentration. I can't give the specific science, but I there are nutrient inhibitors in many greens. Too, it could be due to a very high concentration of minerals. Many greens are high in Iron, which we don't need too much and is easy to over do for a organic veggie lover in america. So on its own, taking in 450% of your daily requirement of Iron through juice may be ok- because that is all the digestive system is putting energy towards, but when you have a variety of others things in there the digestive system is producing enzymes and other stuff for the proteins, fats, carbohydrates. I do remember reading something about fermentation in the gut when combining juice with solids. They say the same thing about mixing fruit with regular meals.
Even though some people may be totally cool with downing a potent juice with a meal, it seems at this point in your life it's not wise.
We all function somewhat differently.
Dr. Mercola has a intro to juicing on his website which is pretty informative.
Some people will mix fats like coconut, flax, hemp, or coconut milk with their juices.
When we mix fat with things the nutrients become more bio-available.
Also, I'm no juicing expert. Though, wheat grass juice is incredible for me.
I use it almost daily as a part of balancing blood sugar issues. - and it has many other incredible benefits.
Any other questions I may help you with? Did I address your questions well?
Don't be afraid to admit you want greens.
Imagine how your creator would react if you yelled, "lord I do not want your greens. They're just kind of here."
Also, it seems large quantities of probiotics for a few months may serve you well. I recommend "Primal defense ultra." above all other probiotics.
That may actually address the issue. Last year I could see myself with the same issue you are experiencing, but now I can mix juices with other stuff with no problem. I also had an intollerance to gluten among many things, and now I have no digestive issues (besides blood sugar) due to that particular probiotic. No other brand was effective- when I started with that things changed dramatically.

Many plants have anti nutritional properties, particularly when eaten raw. You may be overdosing on oxalates or something else that should be taken in moderation. Plants come to us in a slow release form. By juicing, you are forcing your gut to deal with food on an unnatural time scale. Just as fruit juices can cause a sugar spike, those with oxalates etc. may cause a spike in those compounds.

You know how people say "don't eat processed food?" Liquid juice is processed food. When you chew whole food in your mouth signals are sent to your body ( hey, incoming food, sending out the proper chemicals to the stomach & intestines...) When you don't chew celery for example, I'm not convinced the body can digest the juice the same way because I think different chemicals are sent out to the body. I'm jut speculating here but it's the reason I don't juice.

I actually posted this before Xixca, but here it is again (switch "who would consume this quantity of sugar" with whatever green you're juicing)

I personally think you're better off eating the whole fruit or veggie otherwise you're just drinking sugary water which is barely above soda in my book! It reminds me of this quote from The Saccharine Disease

Obesity stems from the appetite being deceived by the unnatural concentration present in white flour and in sugar, so that a person eats too much. For example, the average consumption of sugar today is about 5 oz. per head per day (against less than 1 oz. about a century ago). This 5 oz. is contained in nearly 3 lb. of sugar-beet or in up to a score of ordinary apples. Who would consume this quantity of sugar in its natural, dilute form? The same argument applies to white bread, and other articles containing white flour, as compared with unrefined wholemeal bread.

By following Rule 2, above, the natural fibre (roughage) is restored to the diet, and the natural dilution is restored also. As a result the appetite can again be allowed to regulate the amount to be eaten, as it is designed to do, and we can ignore any question of calories, just as all creatures in the wild state ignore them (and they never suffer from overweight).

Thanks for all your inputs!
We might never know the exact why, but some of it...
I stoped juicing though I might do it again, and I eat my salads.
Actually, a piece of the screw is missing, so it does not work well, this is a hand-powered one, so it is not heating the juice.
Dunno about iron, I thought that greens were especially good for magnesium...

Joshua, I am not afraid to admit I want greens, I do not "Want", I want what I have, I mean I do not focus on greens, it is just that I have a lot, especially now with the rain coming. They give me no work to produce!
I also have taste for bitter, so I love chicory and dendelion.
Then parsley and coriander leaves are so yummy...!

Yes I do eat fat food with it.
If I juice, I chew some pumkin seeds or other, so that I do not swallow the stuff like water!
I hate swallow cold, so I warm up first in my mouth.
So I am sure there is plenty of saliva.

I do know mercola's site and like the information!

I have a probiotic, and a lot of boxes, suposed to be good, will look what it is to tell.
Might try the one you mention if needed...
And sauerkraut would be the best.
