That doesn't mean it isn't a fad. And to be accurate, no it didn't actually happened. The cows you are eating did not exist. Neither did any of the fruits or vegetables. Almost everything you eat is much more modern than the grains you eat. Humans have been consuming grains for at least 100,000 years. There is no evidence to support the notion that grains are bad for us in any way.
Wheat is thought to be only be around 10,000 years old or so. If they were eating grains 100,000 years ago, it certainly wasn't what we are used to eating today.
Additionally, beer is considered by many to be the first significantly consumed product of grain. I don't think you could say modern day beer is completely free of any health side-effects. It gets the blame for quite a number of ailments.
>Wheat is thought to be only be around 10,000 years old or so.
Which is older than all of the vegetables that exist today, and older than cattle or chicken. "This food has evolved over time" is not support for a claim that the food is unhealthy or dangerous.
>It gets the blame for quite a number of ailments.
No, it doesn't? Alcohol does, but that's neither unique to beer nor does it have anything to do with grain.
