Whole Food Formulas Through a Food Pump: Tips for Both ENFit & Non-ENFit Users

With an increasingly large variety of formula available to the tube fed population today (whether they use legacy or ENFit connectors), caregivers now have more options than ever when working with their child’s doctor and/or dietitian to find a solution that meets their nutritional needs in a way that everyone can feel good about.

One option that has grown in popularity is whole food formula – a solution that focuses on using all whole food to deliver a variety of nutrients to tube fed individuals.  And while delivering whole food formulas using a food pump is not recommended by pump manufacturers, we understand that this may be what your child tolerates best, or what simply fits your day to day life.

If you use whole food formulas and this is the method you prefer, we have some tips to share that may make this method of feeding easier. Keep in mind, you can use whole food formulas with both legacy and ENFit connections.

  • Add water: Check with your child’s health care provider to determine the daily free water goal. Use some of that free water to thin out the whole food formula.
  • Strain the formula: Whole food formulas may contain intact food chunks. These chunks clog the food pump tubing and cause food pump alarms. Pour the formula through a clean strainer to remove any chunks. If you have access to a high-quality blender, being able to run your formulas through several times will increase the likelihood of a successful delivery.
  • Be mindful of hang times:
    Whole food formula with nothing added to it, not even water, can be open and unrefrigerated for up to eight hours. The formula, though, may thicken as it sits at room temperature. To thin the formula, run the container under warm water before each feeding. NEVER boil or microwave the formula. Doing so creates a major safety concern and could change the formula content and the availability of its nutrients. If you do not use a whole food formula and instead blend your own food or add blended food to a formula, the hang time is 2 hours.
    • NOTE: Hang times vary by product. Follow the formula manufacturer’s product-specific hang times.
  • Replace the feeding bag: A dirty feeding bag or a defective new feeding bag can cause a food pump alarm. Throw away a feeding bag if it looks dirty after a thorough cleaning. If a brand-new bag causes an alarm, try another bag to see if that fixes the problem.

Alternative Feeding Methods 

Still having issues with delivering whole food formulas using a food pump?

  • Discuss other feeding methods or alternate formulas with your child’s provider.
  • Syringe bolus feeding may be a less frustrating method for delivering whole food formulas. If you would like to explore this method, first discuss it with your child’s provider.

Partial whole food formulas contain only some ingredients that are whole foods. Food pumps have fewer issues delivering partial whole food formulas. If you’re interested in a formula change, discuss it with your child’s provider or dietitian. Either can make sure you have a plan that meets your child’s nutrition needs.
