Put it into perspective. If you're a multimillionaire or a famous film persona, which Woody Allen is both, then you have so many greater rewards that life can offer than a frankfurter. Sure he can give into one of these pleasures, but perhaps, at the cost of a shortened life where he can experience so many more rewards. I respect him for watching out for his diet and health because there are so many other people in similar positions that always make me wonder why they don't take better care of themselves (now that they've "made it") so they can better enjoy what they've been blessed with. To many people this is all obvious.

Many of which are unhealthy or dangerous. Also, I can assure you that after not eating something enjoyable for a long time, the experience is incredible. I was a strict vegetarian for 7 years. When I decided to change that, I walked into a McDonald's (of all places) and ate 10 cheeseburgers. Biting into the first one caused a sensation much like when you realize you're shortly going to sleep with that hot new girl you've been seeing for a while.
IOW, I feel sorry for Woody Allen - he must really miss Frankfurters. Unless he's winding us up and doesn't really think they're enjoyable (it's normally pork too, not kosher, I don't know if he cares). Perhaps he's neurotic enough to fear unhealthy food.

"Taking care" could mean living a bland, boring, ascetic life or exercising, investing time and energy in extending one's life. Either seems unfitting for the lifestyle of people who worked hard to live their dreams and know they will die anyway. They can afford the best medical treatment anyway.
