Multicenter Study
Fatty acids, diet, and body indices of type II diabetic American whites and blacks and Ghanaians.
This research was designed to study the diet, lipid profile, and metabolic and body indices of type II diabetic and non-diabetic subjects among American white and black and Ghanaian populations. ⋯ The data showed a higher metabolism of carbohydrate for energy in the Ghanaian group than in the other groups. In addition, fat metabolism may differ between Americans and Ghanaians. For many variables, black Americans were more similar to white Americans than to Ghanaians. These observations imply that cultural factors may contribute more than ethnic origin to the etiology of diabetes.

Multicenter Study
Is olestra consumption associated with changes in dietary intake, serum lipids, and body weight?
There is considerable controversy regarding the effects of fat substitutes (such as the non-caloric fat substitute, olestra) on Americans' diet and health. This report gives associations of olestra consumption (in savory snacks) with changes in nutrient intake, serum lipid concentrations, and body weight 1 y after these snacks became available nationally in the United States. ⋯ This study found very modest changes in total diet, but no changes in serum lipids or body weight, associated with consumption of olestra-containing savory snacks. However, the low use of olestra by the study sample limited the ability of this study to detect significant effects.
