 Can tuna is on your yes list, but does it matter if they're water packed or oil packed? Well, if they're packed in olive oil, they're perfectly fine, but water is just fine. Try to avoid the ones that are packed in soybean oil or canola oil, which are absolutely no-no's. The reason in general can tuna is on the list and you don't see tuna on the list, can tuna is generally small tuna and they have very little mercury. In fact, there's a couple companies that there is no mercury in their canned tuna. Bigger tuna, shashimi grade has a lot of mercury in it and you should approach shashimi grade tuna cautiously. It should be a special treat. I have unfortunately a number of sushi eaters who do it on a regular basis that have high mercury levels that we have to get down. Why is prosciutto on the yes list, but salami is on the no list? Good question. Prosciutto by law, prosciutto di parma is from especially raised pigs. They're actually fed parmesan cheese rounds and they're aged appropriately. Prosciutto from the United States isn't treated that way. Prosciutto from other countries is not treated that way. Salami as a general rule is probably fairly safe if you know who raised the pig. But we don't in general know the pig. There's no control over that process, hearing the United States and other countries. So prosciutto, di parma that actually comes from that part of Italy has exact standards on what the pigs are fed. I was just in Italy a few weeks ago and had a prosciutto that was raised in Tuscany outside the city of Montalcino by the Ferragamo family. And these pigs were fed acorns, exactly like 5J ham in Spain. And this prosciutto is actually good for you because the fat is actually pure omega-3 fat. And same way with 5J ham. You can find 5J ham on the internet. It's wildly expensive. So try some. It's an amazing treat. But the pigs are fed acorns. So another good source of prosciutto.
