That article describes it fairly well. Please read it.
This also goes into it:

It boils down to pressure to publish, and journals only wanting to publish sensational stuff. It puts the pressure on the researchers to fudge the numbers to get the result they want. It is very widespread. I have no data to back this but I would guess as much as 50 to 60% of research done on any topic is flawed in some major way due to pressure from industry, or pressure to publish (fame route). Both ultimately tie back to money.
People who blindly accept research studies clearly haven't followed the history of research much. Most get disproven, discarded, or corrected over time. Very few stand the test of time.
As to your request for proof, several people over the course of this thread have read your studies and pointed out the flaws in those studies. Minute sample sizes for one seem to be common. I wonder how many studies were done where a researchers said cell towers cause cancer. They then get cancer figures around 100 cell towers and go from data set to data set until they find that one tower that happened to have a disproportionate amount of cancer deaths. They will ignore all the other data that does not agree with them, gloss over that it was multiple types of unrelated cancers, and publish. This is just how the world works.
The part that amuses me is how you seem to think I am a fool for being trusting, yet your trust in a narrow set of questionable research far eclipses my own. What was that phrase you kept using, head in the sand? I don't think so, you however seem a little gullible to me in your absolute trust of anyone who questions a mainstream institution.
You have already said you don't like GMO, would you care to indicate which of the following you agree and disagree with:

2) Homeopathy doesn't work (Also chiropractice, chinese medicine, acupuncture, etc.)
3) Spanking your children doesn't instil any more discipline in them (and is actually abuse)
4) Vaccines are generally safe and do not cause Autism (or any other toxic responses)
5) GMO's are not toxic and do not cause mutation
6) The 9/11 attacks were carried out by terrorists using planes and the buildings fell because of weakened steel beams
7) Man has landed on the Moon
8) There is no such thing as Electro-Magnetic Hypersensitivity and wifi won't harm you
9) Evolution is real and is the best explanation we have of the origin of the species
10) The Earth is round and so are all the planets and stars
11) Planes give off Con-trails at certain altitudes and temperatures. This is just water vapour.
12) There are no secret societies or wealthy families controlling the Governments or Financial systems of the world.
13) The Holocaust really took place and can be proven with evidence and testimony
14) Mass Shootings in the USA occasionally take place and these are not false flag operations
15) The fluoride in our water is not toxic but is beneficial
16) There is no science behind water divining
