Portion Size, Then and Now

By: Liz Monte (View Profile)

Plates

It’s not just food portions that have increased; plate, bowl, and cup sizes have as well. In the early 1990s, the standard size of a dinner plate increased from 10 to 12 inches; cup and bowl sizes also increased. Larger eating containers can influence how much people eat. A study published in the American Journal of Preventive Medicine found that when people were given larger bowls and spoons they served themselves larger portions of ice cream and tended to eat the whole portion.

Prices

32 ounces                                            44 ounces                                 64 ounces
388 calories                                          533 calories                               776 calories
$0.99                                                   $1.09                                        $1.19 

We Americans love to get the most bang for our buck. When confronted with a 32-ounce drink for 99 cents versus a 44-ounce drink for ten cents more, the decision is easy. You’d have to be a sucker not to go big. But our ability to get the most out of our dollar doesn’t always serve us well. Value pricing, which gets us a lot more food or drink for just a little increase in price, makes sense from an economic standpoint, but is sabotage from a health standpoint. A study published in the Journal of the American Medical Association found that Americans consume around 10 percent more calories than they did in the 1970s. Given no change in physical activity, this equates to around 200 extra calories per day, or 20 pounds a year.

What is normal?

Increased portion sizes give us more calories, encourage us to eat more, distort perceptions of appropriate food quantities, and along with sedentary lifestyles, have contributed to our national bulge. Unless you’re trying to gain weight, it might help to reacquaint yourself with serving sizes. The NHLBI tells us that a serving of meat should be the size of a deck of cards while one pancake should be the size of a CD. It’s unlikely that we’ll see a scaling down of food to these sizes anytime soon, so perhaps we should all become familiar with another image: the doggy bag.

This is a good article; it will get people's gears turning. I count calories, and as ridiculous as, say, half a bagel sounds, it is quite filling when you pair it with healthier foods. The common misconception regarding calories is that x number of calories will take x number of minutes of aerobic activity to burn off. People are forgetting that we burn calories just by sitting around doing nothing. You won't need to burn it off if you stay within the range of naturally burned calories every day. So if you burn off 2000 calories a day, you can consume 2000 calories without gaining weight. This number is determined by a number of factors (e.g. activity level, BMI, metabolic rate), and a nutritionist can give you the information. Of course, being healthy isn't just about calories or amount of food, but that's for another article. :)

Yesterday on a walk to the beach, I saw a teenage girl with a mug of soda that was literally as big as my head. The excess in this country has reached such proportions that's it's no longer funny.

Re: the 8 oz coke. From the 50s and well into the 80s, the small bottle was 6 1/2 oz. (i.e., even smaller): http://www.eriessen.dds.nl/bottle_evolution.htm

Oh, and I disagree with some peoples' impressions that it's all "us". If advertisers and marketers didn't know how to get us to eat more and more of the products they are selling, then why would they spend millions marketing these foods to us?

"That's why these [influences] have such power. Almost all of us think we know what we like. We believe we're too smart to be tricked by something so silly, and that's where we really, really, really get tripped up. Because we say: "Hey, come on. Look. I'm a smart guy and no little trick is going to throw me off balance." That's the real power of these habits, and that's what makes them so ubiquitous. We deny that they ever happened to us." -Brian Wansink, author of "Mindless Eating: why we eat more than we think"
