By what mechanisms?
Human stomachs contain hydrochloric acid, plus this wheat is processed and cooked before ingestion.How does the wheat gene survive the processing, the cooking and the stomach acid? After that miracle, how does the wheat gene influence human genes at the cellular level?
Don’t confuse the issue with actual facts or science...
Without being too graphic, check your stool after eating a couple ears of corn. You will see whole kernels that survived intact.
There is no mechanism.
These so called scientists are today’s Luddites.
DDT bad
GM food bad
Hydrocarbons bad
No matter the innovation if it helps people, or people enjoy it, it’s bad.
How many years now have they been telling us that coffee is bad for us? Thousands of studies later there are only benefits.
Cleaning your butt with corn cobs.
Gene’s survive the same way vitamins do... some get broken down, others make it through the stomach/instestine blood barrier for direct absorption.
Asking your question ...think about how medicine works etc. Why are we influenced by hormones etc.
Why do we take some things orally and other intraveneous? That is where your answer rests.
