Sarah mentioned yesterday that there are some healthy foods that work as mood elevators, but those foods aren't necessarily what people turn to when they're feeling low. A new study calculated that people who are sad "eat larger amounts of foods they consider tasty, but unhealthy."

The trial was put on by researchers at the University of Mississippi, who invited participants to watch either a tearful romance, Love Story, or a romantic comedy, Sweet Home Alabama, and monitored the amount of buttered, salted popcorn they ate. Unhappy viewers, those watching Love Story, are 28 percent more than their Reese Witherspoon-watching counterparts. A second experiment drove the point even further home by demonstrating that students reading about a tragedy (accidental deaths caused by a fire, not the Greek sort) were 4 times more likely to reach for M&Ms than raisins when both were set out as options.

It is certainly something to keep in mind the next time you're heading to the theater and are wondering whether to get popcorn and candy or skip the snack bar altogether.

For years, binge-eating has been thought to be an almost entirely secretive, private habit, but some new research by Dr. Gayle Timmerman of the University of Texas at Austin's School of Nursing shows that binge eating may be more likely to occur in restaurants, especially for women. Binge eating is overeating compulsively and in a restaurant that can translate to ordering an appetizer and a dessert when you might only otherwise have been hungry enough for one main course. Women tended to take in an extra 200-300 calories and about 15 grams of fat when they ate out.

The frequency with which the study participants, as well as people in general, eat out is one of the biggest causes for concern. The participants went to a restaurant or got take out on half of all the days they were in the study and when meals out get that frequent, they are no longer "special occasions" calling for indulgence, though that is the mindset than many still have. Another problem is portion size which, when combined with restaurants' "ample delicious food cues," can cause even a disciplined eater to press on with eating when they should have stopped.

This Halloween, parents across the country might try to limit their kids' intake of candy from their Halloween haul, forcing them to limit themselves to one or two pieces a day. But does this teach children the wrong lesson about food? Some experts say that it does. This practice raises up the candies above the level of normal foods and they become something special, something coveted, something to sneak pieces of and hide the evidence. Such habits can set a precedence that will last for the rest of kids' lives and lead to problems with compulsive eating in the future.

Instead of making candy into this exotic and much-desired item, some parents let their kids eat as much candy as they want on holidays like Halloween. They eat fairly balanced meals the rest of the time, but on those few special occasions the kids can go all-out if they want to. This teaches kids to regulate their own intake (especially if they accidentally eat themselves sick once) because they know that indulgence isn't something to constantly be sought out. The kids aren't focused for the whole day on that one piece they will be permitted after dinner and are much less likely to binge eat when they actually do have free-access to treats.

In the Krystal Square Off III World Hamburger Eating Contest in Chattanooga, Tennessee this past weekend, Takeru Kobayashi brought home another championship title by eating 97 hamburgers in 8 minutes. Joey Chestnut came in second, finishing with 91 hamburgers, followed by Patrick Bertoletti in third with 76. All the numbers are up hugely from last year's contest, in which Kobayashi narrowly beat Chestnut with a final total of 67-62 burgers. One other big change from previous years was that the contest was televised on ESPN2, which gives the sport a much wider audience and much more publicity than it enjoyed before.

The contest is known as the "square off" because the burgers that the competitors wolf down are square, but Krystal's burgers hosts the contest because they have been holding eating contests at their stores since the first one opened in 1932. According to company legend, the tradition was set when the second customer challenged the first customer to a head-to-head hamburger showdown.

The book Mindless Eating is about the fact that we encounter a variety of subtle cues in our daily lives that prompt us to eat. For example, we have heard that food porn might encourage overeating, and the size of the plate you use determines your portion size - and larger portions make you eat more. Dieters often speak of "trigger foods," that they just can't seem to stop eating and must pass up altogether to stick with their healthy eating plans, but everyone has food or situation that gives them the same problem.

Once we become aware of these problems we can sometimes control them, though this is a very hard thing to do. It requires an almost constant awareness of what we're eating, which is why food journals can be effective at quashing bad habits. It is also helpful to take a serving at put the rest of the food away, out of sight.

Do you have a "trigger" or some sort? Have you ever almost not realized that you were eating something until it was gone, even if it was just a bowl of berries, and not a plate of nachos? How do you cope with it?

The more food that is put in front of you, the better the odds are that you will overeat or, at least, eat more than you might otherwise. Generally, this is common knowledge, but some researchers put it to the test by giving people both good and bad tasting foods. Specifically, while one group of participants got varying sizes of freshly popped popcorn, another group was given 2-week old stale popcorn (described as "perfectly safe, just a bit funky"). The results proved the theory, when fresh popcorn eaters ate 43% more popcorn when it was served in a large container and stale popcorn eaters ate 34% more.

If the taste of a food isn't enough to stop people from eating it, it's best to control the size of the container that it's in. So do yourself a favor and use smaller plates and bowls, especially for snacking. Or fill up a bowl with healthy fruits and veggies for munching.

Exact portion size can be difficult to determine without measuring (which is an option), but there's too much variation in all those guidelines that compare portion sizes to, for example, the size of a fist. When in doubt, just take a little less that you think you should. At the very least, you'll be eating one less bite at a time - and over time, even a small change like will add up.

Previous studies about the tempting nature of foods have always assumed that the brain functions the same way in all people, but it turns out that some people are more affected by images of food than other people are. When someone's "reward center" was over-activated by temptations - say, a picture of a delicious chocolate cake - they were more likely to give in to those temptations. The study noted that such a reaction could make people more susceptible to forms of marketing and product advertisement, as well as even to other addictions, like drug use or alcoholism.

I know that I prefer to see images of tempting foods in cookbooks and on blogs, but I think it gives me a greater appreciation for the food, not necessarily tempting me to overeat. Indeed, something that is perfectly presented might make me less likely to tuck in, not wanting to disturb the art-like arrangement on my place.  Have you ever been driven to overeat by a picture? Does this mean that we need to add a disclaimer to our Food Porn category?
