There are four basic types of enteral formula: - answer✔✔1. polymeric
2. modular
3. elemental
4. specialty
Polymeric formulas - answer✔✔deliver 1 to 2 kcal/mL and require that patients can absorb
whole nutrients. They include milk-based blenderized foods and commercially prepared whole-
nutrient formulas.
Modular formulas - answer✔✔contain single macronutrients (protein, glucose, polymers, lipids)
and are not nutritionally complete. They deliver 3.8 to 4.0 kcal/mL and are used to supplement
patients' nutritional needs.
