Diet, cardiovascular disease and oral health Promoting health and reducing risk Riva Touger-Decker, PhD, RD, FADA
ardiovascular disease (CVD) is one of the leading causes of death in the United States and globally.1,2 Although mortality resulting from CVD has declined during the past decade, its prevalence and the incidence of risk factors associated with CVD remain high.3,4 Approximately one American dies every 37 seconds of CVD.2 Investigators have outlined roles for oral health care professionals (OHCPs) in primary prevention of CVD through screening in the dental office.5-7 Although CVD risk screening is a valuable preventive approach to detect those at risk of developing disease and refer them accordingly, another preventive strategy is through education, encouragement and reinforcement of healthful lifestyle behaviors such as diet.8-12 The 2000 surgeon general’s report on oral health in America recommended dietary prevention strategies and supported the concept that “oral health is integral to general health.”13 More recently, Lamster and colleagues14 stated that “dentists can become advocates for a general health promotion and disease prevention message.” U.S. inventor Thomas Edison said, “The

ABSTRACT Background. Primary prevention of cardiovascular disease includes screening as well as education and riskreduction efforts. Methods. The author reviewed diet and nutritional risk factors for cardiovascular disease (CVD), as well as dietary approaches to reduce the risk of developing CVD. The author also presented applications for use in dental practice. Conclusions. The multifaceted relationship between diet/nutrition, CVD and oral health supports the role of CVD risk-reduction strategies in dental practice. Clinical Implications. Reinforcement of healthful lifestyle principles may help reduce patients’ risk of developing CVD and improve their systemic and oral health. Key Words.

doctor of the future will give no medication, but will interest his patients in the care of the human frame, diet and in the cause and prevention of disease.”15 Can OHCPs foster this interest among patients to prevent CVD by caring for the human frame with a healthful diet and lifestyle? I will focus on risk-reduction strategies that OHCPs can introduce into their practice settings through promotion of dietary guidelines and healthful behaviors to reduce the risk of developing CVD. DIET AND NUTRITIONAL RISK FACTORS
Among the primary modifiable risk factors for CVD are overweight, obesity (in particular, abdominal obesity), high serum cholesterol levels, type 2 diabetes mellitus and poor diet (Box 11,8-10). Overweight and obesity (as assessed by body mass index [BMI] or waist circumference) also are independent risk factors for type 2 diabetes mellitus and hypertension. Even small amounts of weight loss without a return to ideal body weight can reduce the risk of developing CVD and these comorbid conditions. A total cholesterol level of greater than 200 milligrams per deciliter, a lowdensity lipoprotein cholesterol level of greater than 100 mg/dL and/or a high-density lipoprotein cholesterol level of less than 40 mg/dL reflect dyslipidemia, which can increase a person’s risk of developing CVD. Dietary risk factors include a diet high in total fat (> 30 percent of calories), saturated fats or trans fats; dietary cholesterol (> 300 mg/day); sodium; and calories in excess of needs. Waist circumference, as a more accurate estimate of abdominal obesity than BMI or weight alone, is assessed by using a tape measure at the midpoint between the lowest rib and the iliac crest.16,17 Values greater than 40 inches in men and greater than 35 inches in women reflect a high risk of developing CVD.

Hague and Touger-Decker18 addressed weight screening by OHCPs, and Greenberg and colleagues5 addressed CVD screening. If OHCPs do screen patients for CVD risk, their discussion of the results can be a teachable moment for patients regarding risk-reduction strategies. Beyond screening, OHCPs can integrate approaches to helping patients reduce modifiable risk factors for CVD in the dental office. DIET AND NUTRITIONAL RISK-REDUCTION STRATEGIES
The 12th-century philosopher Maimonides said, “No disease that can be treated by diet should be treated with any other means.”19 Recently, some have suggested charging higher health insurance premiums to people with a certain BMI20 to curb the obesity epidemic, and many states are considering imposing large taxes on sugared beverages.21 However, taxing select foods and people on the basis of their weight will not solve either the obesity or the CVD epidemic. Educating consumers about healthful lifestyle habits can lead to improved diets and lifestyle behaviors. Through education, OHCPs, like other health care professionals, can play a role in primary prevention of CVD. Diet and physical activity.

Likewise, the American Heart Association (AHA) guidelines on adult nutrition and lifestyle goals for CVD risk reduction9,10,12 support diet as the first line of defense in lessening the risk of developing, as well as treating, CVD and include similar suggestions for limiting intake of total and saturated fat. However, in contrast to the TLC diet’s focus on nutrients and energy, the AHA recommendations for CVD risk reduction9 include specific food group suggestions. These recommendations encourage a balance in energy intake and physical activity to achieve and maintain a healthful weight; a diet rich in fruits, vegetables, whole grains and other high-fiber foods; consumption of fish two or more times a week; intake of less than 300 mg of cholesterol daily with minimal consumption of trans fats and partially hydrogenated fats; consumption of foods with reduced or no salt; and minimal intake of foods and fluids with added sugars. The recommendations also encourage consumers to select lean meats and vegetable protein alternatives and consume fatfree and low-fat dairy products. If people consume alcohol, they should do so in moderation. Reducing added sugars. In 2009, the AHA

issued a scientific statement recommending a reduction in intake of added sugar to no more than 50 percent of discretionary calorie consumption per day in an effort to attain and maintain a healthful body weight and to reduce the risk of developing CVD.22 One can calculate discretionary calories by subtracting calories needed to meet daily nutrient needs from total estimated energy (calorie) needs to maintain weight. This recommendation refers only to sugars (as solids, syrups or other liquids) added to foods in processing, preparation or service. Both the AHA and TLC approaches recommend weight loss for overweight people through diet and physical activity. Removing the word “diet,” with its negative connotations, from our vocabulary and replacing it with “healthful eating” is a positive first step in adopting new lifestyle behaviors.

an approach to CVD risk reduction in the dental office. OHCPs can place AHA and TLC consumer education materials in office waiting areas to help educate patients about healthful lifestyles, CVD risk reduction and the associations between oral and systemic health. Box 4 lists online sources of CVD screening tools and other resources for consumers and health care professionals. Clinicians and patients can use the U.S. Department of Agriculture’s MyPyramid tracker as a self-assessment tool to analyze diet quality and plan a diet consistent with the CVD dietary risk-reduction strategies reviewed in this report. KEY MESSAGES
As the obesity and CVD epidemics continue, it is incumbent on all health care professionals to integrate strategies to ameliorate these diseases. As advocates for oral and systemic health, OHCPs— along with other health care professionals—can integrate primary prevention and risk-reduction strategies into their practices. Box 3 provides key talking points that OHCPs can use with patients. In addition, clinicians can reinforce dietary goals (Box 2) during initial and periodic examinations. CONCLUSION
OHCPs have the unique opportunity to help mitigate the CVD epidemic with risk-reduction approaches in the dental care setting. For example, it may be helpful to place signs in the waiting area that state, “As a service to patients, this office provides health promotion screening and education.” In addition, OHCPs can pose global questions to patients about diet quality in five minutes or less and educate them via suggested statements (Box 3). Working as integral members of the health care team, OHCPs can contribute to health promotion and primary prevention of CVD. ■ Disclosure. Dr. Touger-Decker did not report any disclosures.
