With the advent of treatment with ezetimibe, dietary therapy may not be needed.

If dietary therapy is indicated, a diet with the lowest possible amounts of plant sterols is advised. Guidelines are as follows:

  • Eliminate all sources of vegetable fats.

  • Avoid all plant foods high in fat, such as olives and avocados.

  • Eliminate vegetable oils, shortening, and margarine.

  • Eliminate nuts, seeds, and chocolate.

  • Avoid shellfish.

  • Cereal products without germ are allowed.

  • Food derived from animal sources with cholesterol as the dominant sterol is allowed.

Diet is quite restrictive, but references for acceptable commercial products, possible menus, and recipes are available. [29, 30]
