What Gorilla said...
With me I think I would say timing, quantity, and combination, are the most important factors.
If I eat a huge meal sometimes it will take me quite some hours till it's all gone, but I wouldn't say it's really hard
to digest exactly. Also, if I eat a lot of peanut butter I know it's gonna take some time to make its way down into my guts.. but I don't have any difficulty getting it down there really if I give it time. However, if in the event I try to eat something before it's done digesting, especially something that wants quick passage like fruit, then I may have some digestive discomfort.
I find it interesting what Shelby wrote..
A lot of the time, it's the opposite for me: some processed foods are easier for me to digest than raw foods. I don't do fast-food or anything really sugary/unhealthy, but when I cook foods or buy certain pre-packaged stuff (certain mock-meats, soycrisps, bean pasta, protein bars, etc...), I can digest these better than raw carrots, broccoli, salads, etc....
I'd rather it be the other way around!
I feel like the perceived trouble digesting those raw veggies and salad items may have something to do with all of the dietary insoluble fiber in them. You don't actually digest that fiber but it does take some time to empty out of your stomach. This could seem like digestive problems but it may just really be some good cleansing fiber action doin it's thing. Just my two cents.
Cool thread by the way Robert, quite interesting.[/quote]
