:::Dear , happy new year and thanks for your input.  has said everything better than I would have. Just to explain to you my point of view: There's not much doubt that a diet rich in fruits and vegetables is good for coronary artery disease; medical societies and well-known textbooks do say it, and it's included in the article. Mentioning specific diets is OK too, as long as it is supported by good sources. And by good sources one means mostly secondary ones; please read Wikipedia:Identifying reliable sources (medicine), and especially Wikipedia:Identifying reliable sources (medicine):Respect secondary sources. As you already see, Mediterranean and vegeterian diets are already mentioned. I did not think it is justified to mention veganism too (which is a different thing from "eating fruits and vegetables"; as far as I could search it is not adequately supported by the sources. And giving undue wight means that if we do mention it, we'll be somewhat partial unless we include every other dietary intervention that has a couple of studies in favor of it; however, this is not the job of an encyclopedia, but of a (very big) review article.  

 :::Citation no. 45, to the Mayo Clinic website, was removed because the specific URL did not contain info on diet and CAD; and because this very website has been discussed in Wikipedia talk: MEDRS and is not considered a reliable source. The fact that the other studies were written by the same person is not adequate reason to get them deleted, but it does show that their point of view was not very broad. Why don't you also read the editorial from the very journal one of the articles was published? 

 :::Just a question though: what do you mean by: "And the last Part is simply wrong"?  

 :::I'm not saying that the current information on CAD in the article (or the whole article indeed) is at the level that it should be. Why don't you give a hand? You can use the European guidelines on prevention of cardiovascular disease, which is a respected secondary source (though it does not include secondary prevention). 

 :::And a question to everyone, including . Harrison's does mention them in its treatment of CAD section, but is it really appropriate to include lifestyle modifications, which are really secondary prevention, in our treatment section? Isn't Coronary_artery_disease#Secondary prevention best, and enough?
