Abstract:

 

Frequent consumption of nuts is associated with decreased risk of

cardiovascular disease.

 

We investigated the effect of pecans rich in monounsaturated fat as

an

alternative to the Step I diet in modifying serum lipids and

lipoproteins in men and women with normal to moderately high serum

cholesterol.

 

In a single-blind, randomized, controlled, crossover feeding study,

we assigned 23 subjects (mean age: 38 y; 9 women, 14 men) to follow

two diets, each for 4 wk:

a Step I diet and a pecan-enriched diet

(accomplished by proportionately reducing all food items in a Step I

diet by one fifth for a 20% isoenergetic replacement with pecans).

 

The percentage of energy from fat in the two diets was 28.3 and

39.6%, respectively.

 

Both diets improved the lipid profile; however, the pecan-enriched

diet decreased both serum total and LDL cholesterol by 0.32 mmol/L

(6.7 and 10.4%, respectively) and triglyceride by 0.14 mmol/L

(11.1%) beyond the Step I diet,

 

while increasing HDL cholesterol by 0.06 mmol/L (2.5 mg/dL).

 

 

Serum apolipoprotein B and lipoprotein(a) decreased by 11.6 and

11.1%, respectively, and apolipoprotein A1 increased by 2.2% when

subjects

consumed the pecan compared with the Step I diet.

 

These differences were all significant (P < 0.05). A 20%

isoenergetic replacement of a Step I diet with pecans favorably

altered the serum lipid profile beyond the Step I diet,

 

without increasing body weight.

 

Nuts such as pecans that are rich in monounsaturated fat may

therefore be recommended as part of a

prescribed cholesterol-lowering diet of patients or habitual diet of

healthy individuals.
