I don't want to be that guy again (I've been heavily downvoted in every nutrition threads I contributed in HN), please understand that I'm trying to learn and improve myself. But I'm curious how did you come up with a plant-based diet that's not high in sugar. As far as I know pretty much all (except very few) plant based food are very high in sugar. Especially most fruits have exorbitant amounts of fructose. I usually eat high fiber veggies (like broccoli, brussel sprouts, soybeans etc...) but it doesn't give much variety. Remember that most animal based food (eggs, most cheese, chicken, turkey, red meat, fish etc) are 0 sugar. Also, nuts are low carb, high fat but they're very high in Omega 6 (except walnut and some seeds like flaxseed) and there is some research indicating synergy between sugar and Omega 6 for inflammation (I can find the link if you want, but I'm too tired right now). I'm all for veganism but I can never find a suitable vegan cookbook. People say veganism is easy, as far as I'm concerned this is simply not true. If you go full vegan you have absolutely no choice other than soybeans to get adequate amount of protein. Any other protein source such as beans are very high in carbs (e.g. 600 cal of black beans have only 40g of protein (which is only 1/3 of my daily need as a bodybuilder) but have 116g of carbs only 30g of which fiber, in my book a very unhealthy food). And since you cannot supplement your diet with seafood, you have very few choices of Omega 3 sources (various seeds, acai berry, walnut come to mind).
To make myself clear: I think vegan diet is efficient, sustainable and ethical. But there is simply no easy way to go full vegan and get enough macro nutrients (in particular protein, and fats) without getting a lot of sugar. I have a lot of problem with inflammation and even 5g of sugar is too much for me, so it seems like the only plant based food I can eat are soybeans and broccoli. Maybe I'm missing something. Care to help?
