> The answer is that, despite the dietary claims that are made for all kinds of foods, actually substantiating how eating influences human health is notoriously difficult. This. Have you noticed how recommendations change over years? Nutritionists don't have much of a clue, but press usually takes them by the face value and makes a new truth out of their words.

We actually know a lot about nutrition, but if something are good for A and bad for B and you only learn about this stuff through several intermediaries. Then it's going to come across in a very odd miss mash of conflicting reports. Diabetes, heart disease, and Crohn's are just a few examples where diets can make a huge difference. Don't beleve me? Feel free to avoid vitamin C. Wait, no that’s a bad idea. PS: Now if you’re in the search for optimum heath then yea that's a huge unknown. But, if you ever talk to a nutritionist they can actually back up their advice.

  I don't think Crohn's fits your pattern here. My expertise/bias is that I've had it for about 35 years. The topic here is controlling body systems based on the chemistry of what's being consumed. A Crohn's diet has two important factors, which don't really look at the chemicals introduced into the body very much at all. Most important is a purely mechanical component: because scar tissue and adhesions can cause strictures, areas of limited diameter and stretch in the intestines, it's necessary to avoid stuff that might get stuck, like popcorn and other seeds. A second issue, possibly more important but only very poorly understood, is the environment presented to intestinal flora. There's chemistry to that (like carb mix) but, not with respect to the parent organism.

    Most people with Chron's disease should avoid spicy food due to chemical irritation and sure the mechanical issues are also important. However, a nutritionist will suggest a heathy low fiber diet when dealing with a partial obstruction etc. Eggs vs red meat might seem like a simple change, but once a range of dietary restrictions show up a heathy diet becomes a lot more difficult. Anyway my point was there is a lot of practical diet research out there. PS: Chrones also frequently causes issues with nutrient absorption and a high protein diet is useful for healing. So, there are some classically nutrition based changes.

  Did you mean coeliac not crohns?

One of the major issues is that the way to collect info on dietary intake is really hard. It is typically a food diary or a food recall, both of which are flush with issues, all of which are well known to academic researchers, but are passed over by journalists.
