This morning, I read 6 Rules of Good Nutrition on http://eatthis.menshealth.com/slide/beware-portion-distortion. I felt it was so important.

Snack portions aren’t the only things that have increased wildly in size. Since 1977, hamburgers have increased by 97 calories, French fries by 68 calories, and Mexican foods by 133 calories, according to analysis of the Nationwide Food Consumption Survey.

A study published in the American Journal of Preventive Medicine looked at 63,380 individuals’ drinking habits over a span of 19 years. The results show that for children ages 2 to 18, portions of sweetened beverages increased from 13.1 ounces in 1977 to 18.9 ounces in 1996.

One easy way to short-circuit this growing trend? Buy smaller bowls and cups. A recent study at the Children’s Nutrition Research Center in Houston, Texas, shows that 5- and 6-year-old children will consume a third more calories when presented with a larger portion. The findings are based on a sample of 53 children who were served either 1- or 2-cup portions of macaroni and cheese.
