Does the excess carbon dioxide in the produce cause diarrhea in people like me who are sensitive to toxins? I can eat melon, lettuce, celery, cucumber, zucchini, sweet pepper and fennel if they are grown outdoors in a field or a garden. The same produce, if grown in a commercial greenhouse, causes me to suffer nausea and diarrhea.
I asked a greenhouse growers association and a government regulator about this. They both claim that plants do not retain carbon dioxide. I asked them what else could cause my symptoms. They said that there is nothing in a greenhouse that is not in the natural environment. What about the quantity of the nutrients fed to the plants? Too much of a good thing can be bad for our health. Nutrients in the right quantity are good for our health -- excess nutrients are toxic. The greenhouse growers have yet to find the right balance between enough and too much nutrients. Until they sort that out, I eat only field-grown produce.
