Lets agree that modern man has been around for 25,000 years, give or take a few thousand
Grain agriculture has been around for what, 2-3 thousand years, probably less . . .
At least 10,000 years but probably more.
There is evidence of corn being eaten in mesoamerica 20,000 years ago.
So for the MAJORITY of our existance, mankind has sufficed without harvested grains, bread, etc. What did you think primitive hunters ate? Fucking wheat thins? Fish, meat, berries, nuts and that was about it. Disease, particularly colon, became prominent once manufactured grains became the primary energy source.
And you know this how? By comparing 5000 year old colons to 25,000 year old colons?
Bones.
Vitamin d- deficiency f.E.
Vitamin D is produced when the skin absorbs sunlight and is also present in fish but not in any other type of meat. I am not sure how deficiency shows problems with people that eat grains.
And yet rickets is rare in pre-agricultural societies…
I think you are missing the point completely. Rickets is not caused by agricultural. Rickets is caused by lack of nutrients in the diet.
We all know man cannot live on bread alone but that does not mean bread is bad for you.
I totally get the point.
Since the neolithic revolution did indeed lead to an increase of rickets and rickets is likely caused by a lack of calcium (meaning in most cases a lack of vitamin D that helps absorb calcium) a shift in the nutritional behavior of the first city dwellers did indeed cause it.

One straightforward example of what paleopathologists have learned from
skeletons concerns historical changes in height. Skeletons from Greece and Turkey show
that the average height of hunter-gatherers toward the end of the ice ages was a
generous 5’9" for men, 5’5" for women. With the adoption of agriculture, height
crashed, and by 3000 B.C. had reached a low of 5’3" for men ,5’ for women. By classical
times heights were very slowly on the rise again, but modern Greeks and Turks have still
not regained the average height of their distant ancestors.
Another example of paleopathology at work is the study of Indian skeletons from
burial mounds in the lllinois and Ohio river valleys. At Dickson Mounds, located near the
confluence of the Spoon and lllinois rivers, archaeologists have excavated some 800
skeletons that paint a picture of the health changes that occurred when a hunter-gatherer
culture gave way to intensive maize farming around A.D. 1150. Studies by George
Armelagos and his colleagues then at the University of Massachusetts show these
early farmers paid a price for their new-found livelihood. Compared to the huntergatherers
who preceded them, the farmers had a nearly fifty percent increase in enamel
defects indicative of malnutrition, a fourfold increase in iron-deficiency anemia
(evidenced by a bone condition called porotic hyperostosis), a threefold rise in bone
lesions reflecting infectious disease in general, and an increase in degenerative conditions
of the spine, probably reflecting a lot of hard physical labor. “Life expectancy at birth in
the preagricultural community was about twenty-six years,” says Armelagos, “but in the
postagricultural community it was nineteen years. So these episodes of nutritional stress
and infectious disease were seriously affecting their ability to survive.”
So yes, bread probably was bad for them, as bad as it is for the Inuit and the Aborigine now.
To some people carbs are worse than alcohol or cigarettes healthwise and that qualifies as bad in my book.

Why do you assume it was the inclusion of grains rather than a LACK of key things they were getting from the hunter-gatherer diet that caused the problems? The Inuit and Aborgines don’t so much eat whole grains and fruit now as Doritos and Little Debbies. It’s not a fair comparison.
