TBH, when it comes to digestion, I always think of a vegan I know whose farts could be used as biological warfare. I couldn’t eat vegan food only because I tend to go low on B12, iron and vitamin D anyway and those are all things that vegan normally need supplements for, especially the first two ones. Whenever I am low on iron, I know it’s time for more red meat etc., not nut roasts and beetroot salads.
I feel so much better than I did 2 years ago. Maybe it’s the 90 extra lb’s that I’ve lost when switching to plant based eating. Maybe people should eat food without labels. Maybe people should use meat as a spice! Maybe the worst drug in the world is sugar!
Interesting…I too have had several vegan friends who stopped because of unpleasant symptoms (poor circulation, being chronically cold, fertility issues). When I was pregnant I noticed a need for meat and only meat (not even eggs or dairy) would take away this stomach pain I otherwise had.
The longest lived populations tend to be plant-based, whole-foods omnivores, not pure vegans. (See “Blue Zones.”) The concept of veganism is less than 150 years old, and my knowledge there are no indigenous vegan tribes, so there is really scarce epidemiological evidence pro or con. That said, I personally know several thriving vegans, and I’d prefer it any day of the week over SAD (“Standard American Diet.”)
Although plant foods contain minerals in similar amounts to meat, they have very poor bioavailability, meaning that they are not well absorbed. Plants contain phytate, which binds to minerals and prevents absorption. That is why vegetarians (and vegans) are at risk of low levels of iron, zinc and calcium, and need to supplement these along with B12 and the fatty acid DHA.
