I think he is confused with Mexicans, who indulge in lard. Italians eat moderately first of all, which is very important. Although Italians eat pork, it is not the main part of their diet. They eat large quantities of olives, olive oil, raw milk cheese, fresh garden vegetables in the rich Italian soils, rich wines, luscious fruits. I think Americans and Germans are greater pork/lard eaters than the Italians, not to mention they are also greater alcoholics. Italian culture focuses on modesty and moderation in cuisine.
People don't realize how ideal the growing environment and landscape is in Italy for crops. It really is as close to paradise as you can get, especially with the mild winters, nice warm sunny summers and a plentiful amount of rain in the right seasons. Italy has a very rich and diverse agricultural sector. The Slow Organic Foods movement was started in Italy and the Italian farmers are very strict in their standards, contrary to Americans who will just douse their fields full of chemical fertilizers, herbicides, GMO junk, pesticides, hormones and steriods (in the animals). Italia is more traditionale in its way of agriculture. They do things probably closer to the way the Jews did back in the biblical days, focusing on keeping things natural. However, as said in the video, American Italians these days have adopted more of the American American way of doing things and have lost touch with their heritage. THis may be one reason we picture going to an Italian Pizzeria in New York with being unhealthy, because of the Americanization of the establishment.
THese are part of the reasons why Sardegna (Sardinia) has more 100+ year old people than any other place on the earth. I read a great article about this, I will try to find it again.
