Changes in nutrient intake of hypertensives during a behavioral weight-control program.
To evaluate the nutritional adequacy of the diets selected by hypertensive patients participating in a behavioral weight-control program, 26 patients were asked to complete 3-day food records at the start and end of the 8-week program. These records were analyzed using the United States Department of Agriculture (USDA) Handbook 456 data base. Patients decreased their overall caloric intake by 39% during the course of the program and decreased consumption of all nutrients, but only calcium intake decreased to unacceptable levels. There was, however, a significant increase in the number of individuals consuming less than two thirds of the Recommended Dietary Allowances (RDA) for thiamin, niacin, calcium, and iron, and a significant increase in the number of patients who were deficient in three or more nutrients. Thus, although average intake in the behavioral weight-control program was adequate, there was a sizeable number of individuals who were consuming poor diets. Inadequate intake occurred primarily in patients eating less than 1000 calories a day. The simple behavior change of adding a cup of skim milk to the unstructured calorie-counting diet would help restore calcium, thiamin, and niacin to adequate levels.
