My experience has been very different, especially within the past several days, by coincidence. I am finding that certain supplements are providing me with dramatic benefits beyond what raw Paleo has. I'm trying not to get my hopes up so early, but it's exciting. Thank goodness I didn't let the frequent trashing of supplements cause me to not experiment more with them.
Please don't get me wrong, I'm hoping that some day I won't need supplements any more. I just haven't reached that point yet and I appear to be more in need of them than I realized, if the early indications are accurate.
When I've tested boiled and baked potatoes they haven't spiked my blood sugar particularly--less than some raw fruits and raw honey--and I've read many coctivores report that their blood sugar actually went down after adding plentiful potatoes to their diet. IIRC, even the guy who ate almost nothing but potatoes for around a month reported that his blood sugar went down. For me, potatoes give me other problems, but not blood sugar issues. Potatoes, particularly thoroughly fried or high-heat roasted, actually give me more problems than some raw foods that spike my BG much more, which is rather puzzling.
It's interesting that so many raw vegans claim that cooked potatoes are superior to raw avocados. That matches my own experience to a certain extent, though both have negative effects for me, with potatoes just being somewhat less negative, rather than beneficial. I've never noticed any internal benefits from consuming plant fats, not even centrifuged coconut oil (aside from "oil pulling" for helping clean my teeth) or raw coconut meat or water. All the noticeable benefits from fatty foods for me have come from animal fats. I haven't tried fresh durian, though, and I suspect the lack of benefit for me from plant fats has more to do with SAD damage to me than the raw plants themselves, as traditional peoples tend to have a high opinion of fatty plant foods.
Freelea and Durianrider have often condemned eating any animal foods (which includes eggs and fish as well as red meats, poultry and other animal foods) as evil murder, so it will probably take severe health problems before they'll consider eating any animal foods, but I suspect that day will eventually come, and I hope so for their sakes and especially for the sakes of the people they've led down an unhealthy path. It's mildly encouraging that they've publicly acknowledged that 100% raw purity is no guarantee of success and can actually be worse than certain mixed diets. Paul Nison, Matt Monarch and Don Matesz's wife also acknowledged this.
