Pre 70s, we used to naturally consume collagen all the time. This generation prepared food by boiling, roasting and boiling some more, sometimes for hours and sometimes for days. This is exactly how you extract collagen. Not one jot was wasted and if you didn’t clean your plate, you were done for. A swift clip round the ear from granny or mother and you would wipe that plate clean as if your life depended on it. Well, here’s to them, I say, because they were doing us a massive nutritional favour!
People used the whole animal, from the meat, to the innards, to the carcass to make nutrient dense bone broth, a nutrient powerhouse. Everybody ate local and everybody ate meat. Back in the day, ‘Vegetarianism’ was a dirty word and offal was a staple part of your diet. Nothing was processed and it wasn’t until the end of the decade that ready meals were on the menu. This was when it all went wrong! Until then, diabetes, dementia, heart disease and other chronic illnesses were nowhere near the levels they are now. There wasn't a mental health epidemic, and obesity was rare.
