Sure, I understand. I was just parsing it as 'you should eat once a year' (not zero times) - which then didn't seem to tally up with the mentioned risk.

I'd think a small amount every other month or so might be safer - you don't want to look forward to that annual treat and go too crazy!

I see what you are saying. I think the advice was enjoy that one steak dinner a year on a special occasion. Yeah you could also break it up into smaller amounts over the year. I'm largely indifferent to beef but it was a surprising bit of advice from a respected source.
