Call to Action for Nutrition Professionals: Use the Pyramid, Don't Blame it for Obesity

Rising concern over the problem of obesity has led to misguided criticism of the USDA Food Guide Pyramid, but the more pressing concern is the gap between nutrition knowledge and action, reports an article in the July issue of the Journal of the American Dietetic Association.

While the Pyramid is being held accountable by some for expanding waistlines, people are overweight despite their knowledge of the Pyramid and perhaps because they do not adhere to its guidelines, the article contends. The authors point out that those who follow the Pyramid have lower body mass indexes (BMI).

The article, by Jeanne Goldberg, PhD, and colleagues, summarizes the history of the Food Guide Pyramid, noting that it was introduced in 1992 after extensive market research and designed to translate several of the recommendations contained within the USDA Dietary Guidelines for Americans. The much-maligned graphic was actually found to be the best at conveying the three core principles of a healthy diet which are still relevant today-variety, proportionality and moderation-but was never meant to be used as a stand-alone document.

In recapping recent research on the diets of Americans, Goldberg, director of the Center on Nutrition Communication at the Friedman School of Nutrition Science and Policy at Tufts University, notes that adults and children alike are falling short of the recommended number of serving from several food groups in the Pyramid.

Notably, many are also failing to consume the minimum Recommended Daily Allowances for several micronutrients, such as iron, zinc, thiamin and vitamin B-12. According to the authors, research is needed to determine how the Pyramid, and other nutrition education tools, can best be used to combat not only obesity but also micronutrient deficiencies.

"Abandoning the USDA Food Guide Pyramid in favor of an alternate representation is probably not the answer to the country's obesity or nutrition problems, especially as we have no data that show that Americans will recognize another graphic or respond to the information more appropriately," said Jeanne Goldberg, lead author of the article. "The better question is why so many people are more influenced by taste, convenience and cost than by health and how we can change that to create healthier lives."

Goldberg and the other authors on the paper called for dietetics professionals to continue to use the Pyramid to help consumers understand how the complex foods they eat, such as Pad Thai, or beef stew, translate into the a balanced diet. Research is needed, they say, to address which types of interventions are most likely to help consumers recognize and adopt healthful behaviors. Lastly, the authors note that nutrition professionals can capitalize on the widespread recognition of the Pyramid to find new ways to improve public health.

Is too much soy bad for men?

While soy may be beneficial to women in a variety of ways, research in monkeys suggests that it could have an adverse effect on the behavior of men, according to researchers from Wake Forest University Baptist Medical Center. Reporting in the current issue of the scientific journal Hormones and Behavior, the researchers found that in male monkeys, "long-term consumption of a diet rich in soy isoflavones can have marked influences on patterns of aggression and social behavior." Isoflavones are a naturally occurring plant estrogen in soy protein. "Although considerable attention has been directed at the potentially beneficial effects of isoflavones in reducing the risk of various cancers, osteoporosis, cardiovascular disease and postmenopausal symptoms, less effort has been invested in characterizing neurobehavioral effects," according to the study.

Myths stop women breastfeeding their babies

A survey published today by The UK Department of Health for National Breastfeeding Awareness Week (9 - 15 May) shows that serious misunderstandings may be stopping women, particularly young women, from breastfeeding. (1) Although the benefits of breastfeeding are well known (2), the UK has one of the lowest breastfeeding rates in Europe. Almost a third of women (29%) in England and Wales (3) never try to breastfeed compared to 2% in Sweden.(4) Younger women in particular are less likely to breastfeed with over 40% of mothers under 24 never trying. (3) The new survey of 1000 women shows: Myth: Over a third (34%) of women believe that modern infant formula milks are very similar or the same as breast milk Fact: Infant formula milk does not contain the antibodies, living cells, enzymes or hormones present in breastmilk. Breastmilk is designed for each individual baby and changes over time whereas infant formula milk is designed for every baby. -- Myth: A fifth (20%) of young women ...

Too Fat, Too Thin: Weight-Control Behaviors among Girls and Boys The future health of our country's children may rest in the foods they choose and their physical activity patterns. Often children are not eating the recommended servings from the Food Guide Pyramid. Their intake of milk is declining, while soft drink intake and overall food portion sizes appear to be increasing. To examine links between healthful and unhealthful weigh-control behaviors, researchers from the University of Minnesota studied dietary intake patterns of 4,144 middle and high school students. Healthful weight-control behaviors were defined as increasing fruits and vegetables and decreasing foods high in fats and sugars in moderation. Unhealthful weight-control behaviors were defined as skipping meals, fasting, using food substitutes and smoking. Among other findings, the researchers discovered: Girls using unhealthful weight-control behaviors had poorer overall dietary intakes than girls reportin...
