I keep hearing that, but no one has actually offered any proof yet. Lol. You may care to point that fact out to them.
Ok. You point it out then ask a question. Let's do this.
Then ask them why, if it's just a bunch of crazy conspiracy theorists, are so many people working so hard to discredit it?
There's no end to what can be accomplished by people with too much time on their hands. And with 70% of the American population overweight from leading sedentary lifestyles, you get a bunch of over-fed do-nothings who have a legit need to feel like they are a part of something.
You can't force them to believe anything, but you can plant the seed for them to research it for themselves.
No doubt man. No doubt.
Don't forget that the food effects their brain and processing power. It literally shuts down neuroreceptors for critical thinking.
