Does A Healthy Diet Cause Distress?

I don't think it should. 

"Too Many Vegetables? How To Prevent Gas and Digestive Problems Caused By Healthy Eating":

"The number of questions I get from people about bloating, gas and other digestive problems is not small, and since it is a sensitive subject I’m sure the questions I get represent just a fraction of those of you with concerns."

One of the real joys of adopting a "paleo-style" diet has been a great reduction in gas and digestive upset.  "Elimination" is a better way to put it, in fact.  (I originally wrote "near-elimination", but that is not correct, in my experience.) So my inclination is that if you're suffering, that's prima facie evidence that you're not eating a healthy diet.

Ms. Pino has a number of good suggestions, but I think the best one would be to follow a program like the Primal Blueprint or the Perfect Health Diet for 30 days, and see if you can't just eliminate your digestive upset entirely.  It worked for me and for my family.

In my experience, grains, vegetable oils, beans, and starch are the main offenders, in that order.  (Vegetable oils are typically produced from grains or beans, so that's not too surprising.)  Another note: "lactose intolerance" is a typical side-effect of wheat poisoning, and often goes away once wheat is eliminated.  I consider "lactose intolerance" to be a symptom of wheat poisoning, in fact.

So skip the Beano, and skip the beans.  You just might feel a whole lot better.

Ms. Pino's of a similar opinion.
