I didn't know that vegans don't consume sugar.
Some of the most harmful things a person can ingest are embraced as "vegan". Plant based "milk", fruit smoothies, energy bars, fruit yogurt, coconut sugar, brown rice syrup, plant-based margarine, rice cakes, dried raisins, sports drinks, and breakfast cereal will make you obese where meat will not. I've seen vegan salads with 1,400 calories per serving.
The topic was veganism versus eating meat. Sugar wasn't a part of the conversation.
