This is so true. I've tried to go vegan or vegetarian numerous times....going 6 to 8 months was the longest, but I had to give it up because of health issues. My body began to fight against me and I look horrible and became quite ill.<quoted text>
Not everyone can go vegan, some people can't metabolize the nutrients and vitamins from a purely vegan diet - some can't even be true vegetarians.
I knew someone who was vegan for years, no probs. Then one day they started getting problems with their brain. After months of neurology and psychiatry they worked out that their purely vegan diet wasn't allowing some chemical actions in their brain to work. They went back - under protest but wanting to live again - to an omnivorous diet and were fine within months. They were actually suicidal when they were committed.
Fact is, different humans have different genetic predispositions based on heritage and culture. A lot of humans have a pretty omnivorous diet from their culture and heritage, so they are brought into being with a wide range of foodstuffs. Some folks are brought up entirely vegetarian from birth and can't really stomach animal products.
People like the Inuit can subsist solely on seal/walrus/whale blubber for months - sometimes it is stored and almost rancid - but it is a diet that would probably make you or I ill within days.
Today we know more about food than ever and we now know that some people are severely allergic to simple things like peanuts and flour. Decades ago these people would probably just have died and we would have never had known why.
I was talking to a girl the other day that was allergic to sesame seeds - she works at a McDonald's SMDH
I've tried time and time again, only to finally give in because of health issues. Unfortunately, everyone can't be vegetarian. I wish I could, but I can't.
