VRG Testifies for the 2010 Dietary Guidelines
The Vegetarian Resource Group Gave Oral and Longer Written Testimony Concerning Revisions for the 2010 Dietary Guidelines
This was presented to the Center for Nutrition Policy and Promotion at the U.S. Department of Agriculture. Thank you to Suzanne Havala Hobbs and Reed Mangels, who worked on the testimony for VRG. Sue gave the oral testimony, which began:
"My name is Suzanne Havala Hobbs. I am a registered dietitian and faculty member in the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill. I am also a Nutrition Advisor for The Vegetarian Resource Group, a nonprofit educational organization that works with individuals, food companies, professional associations, and others to disseminate accurate information to the public about vegetarian diets."
With some modifications Sue gave exerpts from the longer written testimony. Some excerpts from the written testimony (which differed slightly from the oral testimony, mostly in length) included the following:
The Vegetarian Resource Group is a nonprofit educational organization that works with individuals, consumer groups, food companies, professional associations, government agencies, academic institutions, and other relevant constituencies to disseminate accurate information and sound advice to the public concerning vegetarian diets.
We appreciate the opportunity to share our ideas for the 2010 Dietary Guidelines for Americans. As advocates for people who choose to follow a vegetarian diet, we believe that the Dietary Guidelines should include information about vegetarian diets. This has been done somewhat in the past with suggestions for alternatives to meat products, but information is limited. We also recommend increasing the emphasis on plant-based diets for all Americans.
More than 5 million adults and close to 1.6 million children (under age 18) in the United States have chosen to follow a vegetarian diet. A recent report by the Centers for Disease Control found that, when asked if their child followed a vegetarian diet for health reasons, close to half a million parents/ guardians responded affirmatively; approximately 3.3 million adults reported following a vegetarian diet for health reasons. Reviews by professional organizations such as the American Dietetic Association have concluded that a well-planned vegetarian diet can be nutritionally adequate and provide health benefits. Adding recommendations in the guidelines that will address the nutritional needs of these vegetarians and vegans would strengthen the Dietary Guidelines. For example, non-meat sources of iron and zinc and non-dairy calcium sources could be included.
Addressing nutritional needs of vegetarians would also benefit those who follow near-vegetarian eating plans or who eat several meatless meals each week. As the demographic profile of the United States changes, there is an increase in the number of population groups with eating patterns that do not conform to previous standard U.S. patterns. Many traditional diets are plant-based and may include calcium sources other than dairy products. For example, dairy products are not typically a part of traditional Asian or African diets. Our surveys suggest that the prevalence of vegetarian diets in Hispanic adults in the United States is as high, if not higher, than in white (non-Hispanic) adults. As these population groups become a larger proportion of Americans, their unique dietary features should be considered in the Dietary Guidelines.
We also encourage the Dietary Guidelines Advisory Committee to consider increasing the emphasis on choosing a plant-based diet in the 2010 Dietary Guidelines. A plant-based diet can be defined as an eating pattern characterized by a focus on whole grains, dried beans, fruits, vegetables, and nuts and seeds. These foods are all nutrient-dense and offer significant health benefits in the prevention of cardiovascular disease, hypertension, obesity, cancer, and type 2 diabetes.
The majority of research on health effects of plant-based diets has been conducted on people following vegetarian diets. A vegetarian diet is defined as one that does not contain any meat, poultry, or fish. Studies of vegetarians can provide important insights into the health effects of plant-based diets. Key results include:
- Research in the U.S. and the UK found that vegetarians had a lower death rate from ischemic heart disease than non-vegetarians. The American Dietetic Association's Evidence Analysis Library has concluded that there is good evidence that a vegetarian diet is associated with a lower risk of death from ischemic heart disease.
- Vegetarians had lower blood pressure and a lower rate of hypertension than non-vegetarians. Vegans (vegetarians who avoid all animal products) had the lowest blood pressure and the lowest rate of hypertension compared to lacto-ovo vegetarians, fish-eaters, and meat-eaters.
- In a Seventh-day Adventist population with a generally healthy lifestyle, type 2 diabetes was twice as common in non-vegetarians when compared to vegetarians.
- A study in the UK found that overweight or obesity was twice as common in non-vegetarian men and 1.5 times as common in non-vegetarian women when compared to vegetarians.
- Vegetarian diets with an emphasis on plantbased foods have been used successfully to treat cardiovascular disease, type 2 diabetes, hypertension, and obesity.
In addition to more explicit support of a plantbased diet in the 2010 Dietary Guidelines, we urge the committee to clearly present health concerns with excess consumption of red meat and processed meats. For example, the American Institute for Cancer Research and the World Cancer Research Fund recently concluded that there is convincing evidence that red meat and processed meat increase the risk of cancer of the colon and rectum. There is limited evidence but a suggestion of an association between red meat intake and risk of cancer of the esophagus, lung, pancreas, and endometrium, while limited evidence suggests an association between processed meat and increased risk of cancer of the esophagus, lung, stomach, and prostate. Beef consumption has also been linked to an increased risk of death from ischemic heart disease, while processed meat has been linked to increased incidence of diabetes. The World Cancer Research Fund/American Institute for Cancer Research recommends that red meat intake be limited to an average consumption of no more than 300 grams a week, very little - if any - of which should be processed. A similar recommendation should be incorporated in the revised Dietary Guidelines.
We appreciate the committee's work on Dietary Guidelines 2010 and its solicitation of these public comments.
