You are mis-using the term "cause".
We already know what causes TB. It's called mycobacterium tuberculosis. That some immune systems are capable of fighting & killing it (or, instead, succumbing to it) is a function of the vitality of a given immune system.
AV did not say "cooked green vegetables are involved". He said cooked veggies cause TB. That is a claim I can easily dismiss. As to cooked foods, or veggies, or cooked veggies being involved - well, that is another matter. We already know that many things (including cooking food - especially when one burns it) can compromise an immune system, so that cooking is possible involved is not an assertion with which I dispute.
AV is a bright guy and certainly a ground-breaker, but he needs to be careful of how he uses words like "cause".
It is very rare for a disease to have only one cause. There are usually multiple causes. What one considers to be the primary cause is often a matter of philosophy. The philosophy of conventional medicine, is to blame infectious diseases on microbes/viruses, and degenerative diseases on genetics. The philosophy of naturopathic medicine, is to blame all diseases on toxins, diet, and lifestyle.
For example, T2 diabetes is caused by genetics, diet, and lifstyle. Conventional medicine considers genetics to be the primary cause, and spends billions of dollars on genetics research to find "diabetes genes", while dismissing the dietary component. When a conventional doctor diagnoses someone with diabetes, he might say "you got diabetes because of your genes -- your father had it, your grandfather had it, etc" without saying anything about diet or lifestyle. A naturopath, on the other hand, will tell someone to cut out sugary and starchy food, and not say anything about genetics.
Now, back to tuberculosis. We should be careful to distinguish between facts/observations, and explanations of these facts.
The facts are:
A. If we clinically examine patients with symptoms that we call "tuberculosis", we find damaged lung tissue, and a certain kind of bacterium in that tissue, which we call "mycobacterium tuberculosis".
B. Most mycobacterium tuberculosis infections in humans result in an asymptomatic, latent infection, and about one in ten latent infections eventually progresses to active disease.
Fact (B) implies that mycobacterium tuberculosis, in and of itself, does not cause tuberculosis.
There are two possible explanations/theories/philosophies:
1. The bacteria was floating around in the air, and the person breathed it in. The immune system wasn't able to fight it off, so the bacteria started multiplying, established itself in the lungs, started damaging the tissue, and the person became sick. In a nutshell, the bacteria is the primary cause, and environmental toxins don't play a big role.
2. The person was exposed to toxic substances (cigarette smoke, car exhaust, asbestos, etc.) which damaged the lungs. Some time later, when the body had enough strength and nutrient reserves, it decided to detoxify this damage. It created and/or activated "mycobacterium tuberculosis" to consume the damaged tissue. In a nutshell, the toxin caused the problem, and the body used bacteria as a tool to solve the problem.
(1) is the Koch-Pasteur theory, which has been adopted by modern medicine.
(2) is AV's theory, whose origins go back to Bechamp.
