Alternative fat-restricted diets for hypercholesterolemia and combined hyperlipidemia: feasibility, design, subject recruitment, and baseline characteristics of the dietary alternatives study.

Abstract

Recruiting a large cohort of HC and CHL subjects from an industrial workforce is feasible in a restricted time frame. CHL subjects demonstrate features of the insulin resistance/hypertension syndrome, differing from HC subjects. CHL is sufficiently common relative to HC (2:3) to permit a comparison of dietary responses between the two conditions. Finally, the randomization of HC and CHL subjects to the diets yielded statistically indistinguishable groups, permitting a test of the efficacy of the alternative diets within each hyperlipidemic (HL) category.
