If we’re suddenly involving TV-series, there is the Red Dwarf episode “Me2”, largely involving how Rimmer blames his stalled career on gaspazo (sp?) soup. Meaning his lack of ability to take responsibility for his own mess.
1993 movie “Alive”
I win 
Vincent and Mia’s “date” definitely works for this. Mia really is the five dollar milkshake: insanely tempting, but ultimately not worth the price.
… that has to be one of the stranger things I’ve ever said in my life.
I’d also add The Station Agent, which has some wonderful scenes involving food. Essentially, the food is how Joe manages to thaw out Fin and Olivia; it starts with the “We don’t have to talk… we can just eat” scene and grows to them actually eating and cooking and bonding with one another. Come to think of it, there’s a lot of food as connection moments in that one; Emily sharing her fries with Fin and Fin bringing Olivia groceries in an attempt to reach her. It’s a good food movie.
Leave the gun, take the cannoli
Apocalypse Now, The first meeting where he gets his mission is held over lunch. “If you eat this you will never need to prove your bravery to me again.” And the end with the sacrifice of the bull and Kurtz.
In Point of No Return, Bridget Fonda and some bastard who isn’t me eat ravioli in a rather interesting way.
I just remembered Babette’s Feast! It’s been ages since I’ve seen it, and all I can remember is that a French woman arrives and makes a big dinner. So I looked it up on IMDB:
In Antwon Fisher the title character dreamed of a family feast - a table overloaded with good food. The movie ended with his dream come true.
The dinner with a client scene in Pretty Woman.
In The Tom Hanks Movie Cast Away, crab is highly symbolic and serves as a primal symbol of food as survival and ultimately the progression of civilization and the culinary arts. He begins by sucking on raw crabs to survive at the most primal, then he “discovers” fire and you see him on the brink of starvation savoring a fine crab dinner. Finally, he returns to civilization and is greeted with a lavish banquet where there is a large platter of beautiful King Crab legs prominently displayed. He picks one of the crab legs up and contemplates it wordlessly then tosses it away in simultaneous amazement and disdain, amazed at the bounty and convenience, but with disgust, because he never wants to eat another crab again. In that one silent moment you learn a great culinary irony and truth.
Then there’s Fried Shrimp, Boiled Shrimp, Shrimp Salad, etc… Life is like a box of chocolates. But Gump doesn’t meet your criteria as there are no prominent food scenes.
In Big, I believe there are some food scenes that relate to juvenile and adult tastes and are symbolic of youth and maturity.
The main characters in Withnail and I, two penniless actors, spend a great deal of time looking for food and alcohol, talking about it, and despising the people who have it. Their attempts at getting a decent meal together are pretty far out and hilarious.

Richard E. Grant, who plays Withnail, also appears in the BBC comedy series Posh Nosh. Here he plays a snooty lord who hosts a cooking show with his common wife.

Actually, I believe the crab legs were also leftovers and likely going to be tossed, so there is another layer in this scene demonstrative of unthinkable waste and all that is taken for granted. There is another scene involving ice in a drink that is similar.
In Léon (The Professional), we see several scenes where Leon drinks milk. We would expect a cold-blooded killer like Léon to drink something a little stronger. The milk is there as a symbol of his inner innocence.
In Brokeback Mountain there is a Thanksgiving dinner scene. Jack’s father-in-law (who is also Jack’s employer) assumes the task of carving the turkey, showing that he is in charge of the family. A family fight breaks out over whether or not to leave the football game on during dinner. Jack stands up to his father-in-law and shouts him down. After the argument, Jack takes over carving the turkey.
The Blues Brothers scene in the fancy restaurant where they convince their trumpet player to give up his job and come play in the band. Followed by the scene in the diner.
My Memory is hazy on this one, but I believe there were some highly symbolic food scenes in The Witches of Eastwick. The movie was pretty racy, but I think still within your limits.
In Girl, Interrupted… the whole thing with Daisy and the chickens and then the scene in the ice cream parlor
How about Oliver! - “Food Glorious Food” and the starving boys and the fat old men with their feast.
The dinner scene in Psycho.
The Good, The Bad, and The Ugly has a couple of scenes involving food. The first prominent one has Angel Eyes talking to the man he has been sent to kill, talking to him about why he has to kill him, meanwhile treating himself to some of the food that the man’s wife had just prepared for the family.
There’s a later scene in the same movie that I can’t quite remember (I’ve only seen the whole movie once) after Tuco meets Angel Eyes at the POW camp that involves food and drink, and the band of POWs playing music outside (IIRC, someone, either Tuco or Blondie, is being beaten senseless during the song).
The Hornblower movies, starring Ioan Gruffudd, feature food prominently on a number of occasions. In The Duel, Midshipman Hornblower is introduced to “The senior officer of the Midshipman’s Mess”, Midshipman Simpson, who acts as a dictator over the other midshipmen via intimidation and abuse. The first thing he does after meeting Hornblower is to reach accross the table to help himself to Hornblower’s first meal aboard the ship, demonstrating his power by depriving Hornblower of his share of the ship’s rations.
Later on in the same movie, Hornblower finds himself in command of a captured French ship carrying a cargo of rice and wine, later discovering that, due to a hull breach below the water line from the brief battle that led to the ship’s capture, the rice is swelling inside the cargo hull, eventually tearing the entire ship apart. Hornblower finally becomes top dog, and he loses it because he had too much food under his care (and because someone previously hit the ship with a cannon, but that’s not important).
The next movie in the series, The Fire Ships, revolves around the difficulty the Royal Navy is having supplying their base at Gibraltar, and by extension, the Mediterranean Squadron, with sufficient food to feed the men. One scene features a seaman going on about how they have to eat stale ship’s biscuits, while the officers are dining on steak and wine, and the next scene shows the ship’s captain knocking a stale biscuit on his table top to get a mealworm out from inside of it before taking a bite.
I just thought of another one: the scene in Ordinary People where the son, Conrad (played by Timothy Hutton) tells his mother (played by Mary Tyler Moore) that he’s not hungry, and she responds by putting his breakfast down the garbage disposal - an act that reveals the coldness and hostility she feels toward him.
Ain’t ever seen Tom Jones and I’d say I understood the Flashdance scene well enough, thanks.
Alternative interpretations of the milk in Léon: he has ulcers; he doesn’t drink alcohol in order to keep a clear head.
While You Were Sleeping - Dinner scene involving “creamy mashed potatoes”–comfort food. Also, a scene where hot dogs are ordered from a street vendor who remembers one person’s “usual” order but not another. A scene where the heroine dips her oreo in her cat’s bowl of milk.
Crocodile Dundee - The scene where Mick provides food scavenged from the “bush”–“It tastes like shit, but you can live on it” and then opens a can of beans. Contrast with later scene in New York with street vendor.
Pride and Prejudice - Dinner scene where Mrs. Bennett is appalled that Mr. Collins would think her daughters helped with preparation.
Galaxy Quest - Food synthesizer provides “actor-alien” with live bugs to eat.
Home Alone - Kevin’s brothers eat all of the cheese pizza that was ordered for Kevin.
The Santa Clause - the TV sequence about a perfect Christmas dinner, followed by the reality of the burned turkey and then the trip to Denny’s.
Krippendorf’s Tribe - A number of scenes involving food, but my favorite is the one where he drinks milk directly from the carton, it’s sour, and he says “March 10–what good does that do, I need a year.”
Animal House - The food fight scene.
I’m not sure if these fit your definitions. But I think the analyses would be interesting.
Two more:
Fifty First Dates The repeated breakfast scene involving waffles. The symbolism of her “waffling,” etc.
Overboard - Quite a few scenes–I like the one(s) where school lunches are being packed and then the table is vacuumed; there’s also one where a pie plate is superglued to someone’s hands.
