Americans still not eating enough fruits and vegetables, according to two recent studies

March 19, 2007

"Eat your vegetables" has been heard at the dinner tables of America for a long time. Has the message gotten through? Since 1990 the Dietary Guidelines for Americans has recommended consuming at least two servings of fruits and three servings of vegetables daily. However, two studies published in the April issue of the American Journal of Preventive Medicine clearly show that Americans are not meeting the mark. This is a serious public health concern because consuming a diet high in fruits and vegetables is associated with decreased risk of obesity and certain chronic diseases, such as cardiovascular disease, diabetes and some cancers.

Researchers from the Johns Hopkins School of Public Health and the Welch Center for Prevention, Epidemiology, and Clinical Research in Baltimore analyzed NHANES data (National Health and Nutrition Examination Surveys) to determine trends over time for fruit and vegetable consumption among American adults. The answers are not encouraging. Despite campaigns and slogans, Americans have not increased their consumption, with 28% and 32% meeting USDA guidelines for fruits and vegetables, respectively, and less than 11% meeting the current USDA guidelines for both fruits and vegetables.

The study included 14,997 adults ( ≥18 years) from 1988 to 1994 and 8,910 adults from 1999 to 2002 with complete demographic and dietary data. Approximately 62% did not consume any whole fruit servings and 25% of participants reported eating no daily vegetable servings. There was no improvement in Americans' fruit consumption during this period and there was a small decrease in vegetable intake.

In the article, Tiffany Gary, PhD, states, "Low fruit and vegetable consumption with no indication of improvement between 1988 and 2002 as well as consumption disparities across ethnic, income, and educational groups should alarm public health officials and professionals. With two thirds of the U.S. adult population overweight or obese, the implications of a diet low in fruits and vegetables are extensive... New strategies, in addition to the 5-A-Day Campaign, are necessary to help Americans make desirable behavioral changes to consume a healthy diet that includes a variety of fruits and vegetables."

Previous studies have shown a disparity in the diets of blacks and whites, as well as a more serious disparity in the incidence of heart disease, cancer and stroke. A second article published in the April issue of the American Journal of Preventive Medicine examined whether the diets of non-Hispanic blacks have improved relative to the diets of whites.

Also working with the data from the National Health and Nutrition Examination Surveys (NHANES) I (1971-75); II (1976-1980); III (1988-1994); 1999-2000; and 2001-2002, researchers found that little progress has been made in closing the gap between blacks and whites. In fact, the authors point out that the results are remarkable for similarity of trajectories in all race-gender groups. The quantity of food, total energy intake, energy from carbohydrate, and energy density increased, and energy from total and saturated fat and cholesterol intake decreased across the board. These results suggest a population-wide shift in intake of energy and macronutrients over the 3-decade span of the four surveys and may reflect changes in diet that were adopted by all race-gender groups.

Dr. Ashima Kant, PhD, Queens College of the City University of New York, concludes, "Dietary intake trends in blacks and whites over the past several decades appear to be similar - suggesting that previously identified dietary risk factors that differentially affect black Americans have not improved in a relative sense. The differences observed need to be confirmed with biomarkers, but would seem sufficiently strong to warrant intensified study and action to better understand the sociocultural or environmental factors that anchor these persistent differentials and identify approaches to effect change while building on strengths of current dietary patterns where possible."

Emphasizing the need to encourage proper diet, Linda C Nebeling, PhD, MD, RD, FADA, of the National Cancer Institute, NIH, states in a commentary in the same issue, "The majority of U.S. adults continue to consume fewer than five servings of fruits and vegetables daily. Increases in public awareness of the importance of and recommendations for fruit and vegetable consumption are yet to be accompanied by increased intake, demonstrating the need for a reinvigorated effort to promote fruit and vegetable consumption. On March 19, 2007 'Fruits & Veggies-More Matters' will be launched. This effort will build on the strong public-private partnership begun in 1991 by the 5-A-Day for Better Health Program."

Dietary vegetable oil consumption on glucose levels, in diabetic mice

Dietary vegetable oil consumption on glucose levels, in diabetic mice
by Robert Amadu Ngala (Author), Isaac Ampong (Author)


Increasing evidence implicates dietary fat composition in the development of insulin resistance, including impaired fasting glycaemia and Type 2 diabetes mellitus. Most patients with type 2 diabetes are obese and have elevated plasma free fatty acids concentrations and these have been shown to inhibit insulin-stimulated glucose uptake. The Randle glucose-fatty acid cycle has been used to explain insulin resistance in skeletal muscle of patients with type 2 diabetes or obesity. Here we show that some plant vegetable oils: Groundnut (Arachishypogaea) oil, Red palm (Elaeisguineensis) oil and coconut (Cocosnucifera) oil rather stimulate glucose uptake in type 2 diabetic mice fed on 10% by weight of these vegetable oil in rodent chow. The oils did not impair glibenclamide effect on diabetes...

Fruit and Vegetable Consumption and Risk of Epithelial Ovarian Cancer: A Comparative Analysis of the Impact of Calibration of Dietary Data in a Multi-Center Study

Fruit and Vegetable Consumption and Risk of Epithelial Ovarian Cancer: A Comparative Analysis of the Impact of Calibration of Dietary Data in a Multi-Center Study
by Mandy Schulz (Author)


From a prospective point of view, the association between fruit and vegetable consumption and risk of ovarian cancer remains unclear. Therefore, the present study was to investigate the association between consumption of fruits and vegetables and risk of the development of epithelial ovarian cancer in a multi-center large scale cohort study. Special attention was paid to the evaluation of the impact of calibrating multi-center dietary data. High consumption of fruits and vegetables did not reduce the risk of developing ovarian cancer. There was suggestive indication for a positive association with risk of ovarian cancer among very low fruit and vegetable consumers. Also, data indicated an inverse association between a high consumption of garlic and onion vegetables and ovarian cancer...

Fruit and Vegetable Consumption by School Lunch Participants: Implications for the Success of New Nutrition Standards
by Constance Newman (Author)


Following the Healthy, Hunger-Free Kids Act of 2010, USDA instituted many changes to the National School Lunch Program (NSLP). School lunches have had to meet new nutrition standards since the fall of 2012. Using data collected as part of the 2005 School Nutrition and Dietary Assessment III, this report examines whether students who attended schools serving more fruits and vegetables, in amounts that would meet the new standards, actually ate more of them than students at schools that did not. Student consumption data were matched by date to lunch menu records for the same day. Tobit models were used to estimate consumption of fruits and vegetables in school lunches by NSLP participants, controlling for other characteristics of students and school food operations. Students in schools that...

Fruit and Vegetable Consumption by Low-Income Americans: Would a Price Reduction Make a Difference?: Economic Research Report Number 70

Fruit and Vegetable Consumption by Low-Income Americans: Would a Price Reduction Make a Difference?: Economic Research Report Number 70


Americans’ diets, particularly those of low-income households, fall short of Government recommendations in the quantity of fruits and vegetables consumed. Some proposals suggest that a price subsidy for those products would encourage low-income Americans to consume more of them. This study estimated that a 10-percent subsidy would encourage low-income Americans to increase their consumption of fruits by 2.1-5.2 percent and vegetables by 2.1-4.9 percent. The annual cost of such a subsidy for low income Americans would be about $310 million for fruits and $270 million for vegetables. And most would still not meet Federal dietary recommendations.
