As I was reading the original article, I wondered if the FDA has any regulations about this sort of stuff (&quot;What constitutes a tomato? When is something no longer a tomato?&quot;)<p>I did find a bit about naming different types of canned tomatoes[1]. I would have had no idea that there is such a difference between &quot;tomato paste&quot; and &quot;tomato puree&quot; and they even have regulations about how many seeds and peels and such can be in the can.<p>So, even reading all the ingredients and everything on the can, there may be some hidden terminology you may not know about in the way the food is named. Very interesting.<p>[1] <a href="http:&#x2F;&#x2F;www.accessdata.fda.gov&#x2F;scripts&#x2F;cdrh&#x2F;cfdocs&#x2F;cfcfr&#x2F;cfrsearch.cfm?fr=155.191" rel="nofollow">http:&#x2F;&#x2F;www.accessdata.fda.gov&#x2F;scripts&#x2F;cdrh&#x2F;cfdocs&#x2F;cfcfr&#x2F;cfrs...</a>
