Use of an expanded-whole-wheat product in the reduction of body weight and serum lipids in obese females.

To achieve weight reduction and alter serum lipid profiles, an air-expanded whole-wheat protein product (SNW) was used by moderately obese women as a meal substitute for 12 wk. Results were compared with those from a standard low-calorie diet (LCD). The SNW group lost 3.9 kg (means) over the first 6 wk and a further 1.6 kg between weeks 6 and 12. In contrast, the LCD group lost 2.8 kg during the initial 6 wk but failed to achieve weight loss during the second 6 wk. Consequently, the SNW group lost nearly twice as much weight over the 12-wk period as did LCD participants. A beneficial effect of SNW on serum cholesterol and triglycerides was noted; both measures declined in conjunction with the weight loss. Such alterations were greater in the SNW group than in LCD participants. Both schemes proved safe. SNW is safe and effective in weight reduction and serum lipid modification in moderately obese women.

The cross-cultural study of U.S. and Greek adolescents: blood pressure data.

Blood pressures (BP) were determined in 1409 boys aged 8-16 years at three one-year intervals in New York City (NYC) and in Greece, areas of high and low incidence of coronary heart disease (CHD), respectively. Non-Greek American boys had significantly lower systolic and diastolic BP than all the Greek boys from NYC and from Greece. The boys residing in Crete and in Athens had higher BP than all other cohorts. After covariance adjustment for height, ponderal index and age, significant differences among the cohorts showed the non-Greek American cohort to have the lowest and the Cretan cohorts the highest BP levels. The Cretans lead a lifestyle noted for the absence of other risk factors for CHD. Thus, while the incremental increase in blood pressure might have a corresponding increase in CHD risk among individuals, there are fewer individuals in Crete at elevated risk overall based on the CHD experience of the U.S. and Greece.
