PMI® Purified TestDiet®: Carbohydrate Series (using Basal Diet 5755)

Fat (Lipid) Modifications to Purified Diets

We can alter the fat concentration of any purified diet; diets with high and low fat concentrations are possible. Fat levels are usually adjusted by making adjustments to the carbohydrate level or, sometimes, to the protein level of the diet. These formulas can be "calorie-balanced" or "quantity-balanced." (For more information see About Diet Formulas.)

Typically the fat in purified diets is obtained primarily from lard, although virtually always there will be some vegetable fat in order to proved essential fatty acids (EFA). Occasionally other sources of fat will be used in addition to or in place of lard: oils such as soy, corn, coconut, cottonseed, peanut, sunflower, safflower, olive; and other fats such as beef tallow, butter (anhydrous milk solids), and hydrogenated vegetable fat ("Crisco").

Many examples of calorie-balanced fat-adjusted diets can be found at the Diet-Induced Obesity page and in the chart below.

As another example, TestDiet^® #5755 Basal Diet has been modified to create a low EFA diet and two high-fat diets.
