The GAPS diet is anti-starch, claiming it's more difficult to digest than monosaccharides. However, I've seen Paul Jaminet describe white rice (pure starch) as perhaps the most readily digestible carb source.
Many in the paleo community are anti-fructose, and there seems to be evidence that it uniquely feeds pathogenic bacteria.
VLC and LC diets notwithstanding, what carb source would you prefer for maximizing gut health? Ripe bananas seem like a good option for reconciling the two positions. My problem with bananas is that, for me, they have a poor (high) reward/satiety ratio.
This question is somewhat academic- for practical purposes I usually vary my carb sources. Just curious to hear thoughts from you all.
