Pecan-supplemented diets were studied in 17 hyperlipidemic individuals who were randomly assigned to pecan (6 women, 2 men, age 46±6 years [mean ±SD]) or control (7 women, 2 men, age 53±10 years). The pecan group consumed 68g of pecans/day for 8 weeks. Total fat, monounsaturated fat, and polyunsaturated fat intakes were significantly higher in the pecan group. LDL cholesterol was lowered in the pecan group from 152±21 mg/dL at entrance to 136±22 at Week 4 but was 153±33 by Week 8. LDL cholesterol was significantly lower in the pecan group than controls at Week 4 (136±22 mg/dL versus 173±60). Total cholesterol in the pecan group was 233±19 mg/dL at entrance and 221±18 by Week 4 but was 232±35 by Week 8. Total cholesterol was significantly lower in the pecan group (221±18 mg/dL) than controls (257±60) at Week 4. Pecans in diets of hyperlipidemic individuals did not have sustained serum lipid lowering.
