Lulu,
Please don't worry yourself too much over what one person says. You will soon learn there is no "one" right way. Instead there are all sorts of variations and exceptions to what we as individuals can tolerate. All you can do is read about what works for different people, and test new foods and ideas, and then see what works for you. Then you will have all the power to decide what works for you and what doesn't!!
Everyone is just out there giving it their best shot, and sharing what works for them!!!
I quickly glanced at the link you provided regarding the almond flour and I hope you noticed this author said the same thing, "You may feel more energy or have less pain and inflammation. You may not. We’re all unique, so you have to experiment and discover what best fuels your body."
And when I first when grain free years ago, I way overdid it on almond flour goodies, and I am sure that is what she is getting at, as too many almond flour pancakes, cookies, and baked almond flour breads is not the best idea. Keeping this limited diet as varied as possible is our true challenge.
I'm now a KICK AS (and Kick IBD) success story!! After going low starch Paleo to heal my gut, I can now eat nearly all starches, grains & foods without inflammation, flare-ups, or pain. I used a modified SCD diet approach (minus dairy! plus cacao ♥). Cheers to healing & thriving again! I blog at
