    Modifying USDA food menus for a cholesterol-lowering diet resulted in a slight cost increase at the low-cost level and a small decrease at the moderate-cost level. These cost differences were not statistically significant.

    Area of Science:

    • Nutrition Science
    • Dietary Economics

    Background:

    • Dietary cholesterol intake is a significant public health concern.
    • The United States Department of Agriculture (USDA) provides food plans at various cost levels.
    • Cholesterol-lowering diets often require specific food choices that may impact cost.

    Purpose of the Study:

    • To compare the cost of cholesterol-lowering diets based on USDA food plans.
    • To determine if modifying USDA "moderate-cost" and "thrifty" menus to meet cholesterol guidelines affects their price.

    Main Methods:

    • USDA "moderate-cost" and "thrifty" weekly menus were adapted for a cholesterol-lowering diet.
    • Prices for individual food items were collected from two major supermarkets.
    • Average prices were calculated for both the original and modified menus.

    Main Results:

    • The modified moderate-cost, cholesterol-lowering diet was $1.37 cheaper than the original USDA moderate-cost menu.
    • The modified thrifty, cholesterol-lowering diet was $0.22 more expensive than the original USDA thrifty menu.
    • Statistical analysis (t-test) indicated no significant cost difference for either modified menu compared to the original USDA menus.

    Conclusions:

    • Adapting USDA food plans for cholesterol reduction can lead to minor cost variations.
    • The economic impact of cholesterol-lowering diets based on USDA plans is not substantial.
    • Further research could explore a wider range of dietary patterns and cost factors.
