I remember reading about this many, many years ago, so I tried to see if it was archived somewhere on this newfangled internet thingy.
After the the close of WWII and Indian independence, many Hindus opted to settle in Great Britain. They ate their traditional foods, imported from abroad. This population of Hindus began to show signs of malnutrition.
Analysis of their imported foodstuffs did not provide an answer. It was only when the same foodstuffs were analyzed back in their homeland was the riddle solved. There was so much bug contamination, it was supplementing their vegetarian diet. This contamination was absent in the British versions, due to strict import controls.
A most beloved niece is the latest victim to the New Age Dark Age Vegan fad. I've seen what Veganism does to women wanting to bear children. Like I said, Darwinism in action. Not to mention an extravagant waste of resources, environmentally. These asshats all seem to think that crops and textiles (clothing) don't exist at the price of a lot of water, land, and manipulation. Dopes -- that broccoli they and I love (Sorry, HW), that great California Pinot Noir, all those wonderful peaches, the tomatoes in my marinara sauce, etc. etc. etc. -- the production of all of it requires death of animals. It kills all the birds and snakes and lizards and foxes, etc., that used to live on the land where the crops grow now. Lack of water in certain creeks and rivers and lakes kills frogs and fish and who knows what else. Meanwhile, all those critters THRIVE in land where livestock grazes ... but that's supposed to be bad because that's mean to animals, that's meat and dairy, and Vegans think that's awful.
Bah. Dopes.
