1943 USDA nutrition chart
2011 USDA's MyPlate
With the reveal of the new food plate from the USDA, nutrition has been in the news lately. An article on NPR’s Morning Edition recently discussed “Washington’s long tradition of trying to guide the American diet”. From turn of the century agricultural expeditions to “the Poison Squad”, a group of young volunteers who explored the effects of contaminated food in the basement of the Department of Agriculture, this report chronicles the relationship of government and nutrition.
If you’re in DC this year, a new exhibit, “What’s cooking, Uncle Sam? The Government’s Effect on the American Diet” at the National Archives details America’s food history.

Every March the American Dietetic Association sponsors National Nutrition Month. One fun feature of their website is a fad diet timeline; I don’t think I would have wanted to try Lord Byron‘s vinegar & water diet (1820) or the sleeping beauty diet (1976) which featured heavy sedation for several days.

“The average American gains five pounds over the holiday season.”
It’s a common assertion over the holiday season, but where is the evidence?
“A Prospective Study of Holiday Weight Gain” from the New England Journal of Medicine (published March 23, 2000) investigated this claim and found that Americans experience a net 0.48-kg weight gain in the fall and winter. “Since this gain is not reversed during the spring or summer months,” the study found, “[the weight gained] probably contributes to the increase in body weight that frequently occurs during adulthood.”
Two more recent studies also investigate the 5 pound phenomena.
“The effect of the Thanksgiving holiday on weight gain.” from the Nutrition Journal (published 21 November 2006) and “The effect of the holiday season on body weight and composition in college students” from Nutrition and Metabolism (published December 2006) assessed potential changes that occur in body weight during the Thanksgiving holiday break in college students and found participants gained a significant amount of BW (0.5 kg) during the Thanksgiving holiday. “While an increase in BW of half a kilogram may not be cause for alarm,” the authors noted, “the increase could have potential long-term health consequences if participants retained this weight gain throughout the college year.” In fact, although average body weight remained relatively unchanged from pre-Thanksgiving to post-New Year’s, a significant positive relationship existed between the change in BMI and percent fat, total fat mass, total fat free mass, and trunk fat mass for the pre-Thanksgiving and post-New Year’s visits.
So what is to be done about it?
A study from the International Journal of Obesity (London) looked at “The role of conjugated linoleic acid in reducing body fat and preventing holiday weight gain.” Conjugated linoleic acid (CLA), is a naturally occurring dietary fatty acid shown to reduce body fat in animals. In a randomized, double-blind, placebo-controlled study among overweight adults, 3.2 g/day CLA significantly reduced body fat over 6 months and prevented weight gain during the holiday season. “Although no adverse effects were seen,” the study reports, “additional studies should evaluate the effect of prolonged use of CLA.”
