Milk,etc
regular fiber intake is usually recommended for those, who have problems with constipation, on the other side, it is not recommended to drink/eat milk products. Is it ok to eat yogurt and drink probiotic drinks like kefir in this case?
Katherine Hobson: Great question, and one I'll try to answer in a future On Fitness blog post!
fiber in the diet
What are the most effective sources of dietary fiber for those who are on gluten free and lactose free diets?
Katherine Hobson: Great question. Look for an upcoming On Fitness blog on this very topic.
Prebiotics
It is great to see prebiotics beginning to gain coverage and mention in the mainstream media! Thank you for helping make more people aware of this significant element in a healthy diet.
However, every medical authority, research study and solid peer-reviewed analysis I've ever seen would say you have it exactly backward regarding prebiotics.
Inulin is quite clearly a true prebiotic and meets the accepted 1995 definition propounded by Marcel Roberfroid. It doesn't merely have "prebiotic effects." In fact, the vast majority of research demonstrating all the great benefits of prebiotics has been performed using Oligofructose and Inulin precisely because they are clearly and unarguably prebiotics.
Starch derivatives, conversely, may have some 'prebiotic' type effects but would not likely be considered a true prebiotic by a scientific authority - that is, they are not a substance selectively fermented by desirable gut bacteria but not by undesirable bugs.
While I do not wish to try and make this a "plug" for my company, I will point out that we have collected a ealth of authoritative third-party research on prebiotics summarized at http://www.jacksongi.com/content/research.aspx.
