The British news media The Independent published a list of Academia Barilla's do's and don'ts of Italian eating. The list is designed to teach foreigners (in this case, anyone but Italian's) the proper ways to enjoy Italian cuisine. For a culture who doesn't like being told what to do, they sure love instructing others.
Here is an abbreviated version.
And the list explains some definite don'ts.
-Never drink cappuccino during a meal.
-Risotto and Pasta rarely accompany a meal like a vegetable. They are considered courses in themselves.
-Don't put oil in pasta water.
-Never put ketchup on pasta. (I don't think you have to be Italian to find this practice offensive.)
The list seeks to clarify some misconceptions...
-Spaghetti Bolognese isn't accurate. Tagliatelle, the larger noodles are served with Bolognese sauce.
-Caesar Salad is not Italian.
-Fettuccine Alfredo is a dish of noodles, butter and Parmigiano- Reggiano cheese, not a cream sauce.
And continues with sensible advice...
-Share food with those that you love!
