banana puree

Also known as: Musa spp., Banana puree, Mashed banana

Overview

Banana puree is a mashed form of ripe bananas derived from the fruit of Musa species. It serves as a natural, nutrient-rich food product and is utilized as a nutritional supplement, food thickener (particularly in infant feeding for dysphagia), and ingredient in smoothies and functional foods. It is characterized by its high content of carbohydrates (mainly sugars and fiber), potassium, vitamins (notably vitamin C and folate), and antioxidants. While research on banana puree specifically as a supplement ingredient is still emerging, there is more extensive data available on whole bananas and their nutritional benefits. The available evidence primarily consists of nutritional studies and clinical feasibility trials, with limited direct randomized controlled trials (RCTs) or meta-analyses.

Benefits

Banana puree offers several evidence-based benefits. It acts as an effective nutritional thickening agent, achieving desired consistency levels (IDDSI Levels 1-3) for infants with dysphagia, facilitating safer feeding without compromising nutrition, provided it is limited to ≤15% of feeding volume to avoid excess potassium intake. Furthermore, bananas provide potassium, fiber, folate, and antioxidants, which support cardiovascular health and blood pressure regulation. The fiber and water content in bananas also promote regular bowel movements and can aid in electrolyte replacement during diarrhea. Secondary benefits include potential mood enhancement and glycemic control due to the fiber content and nutrient profile. Infants with feeding difficulties (dysphagia) and individuals with diabetes can particularly benefit from banana puree when consumed appropriately.

How it works

The mechanism of action of banana puree is primarily attributed to its nutritional content. The potassium, fiber, and vitamins present in banana puree support various physiological functions, including electrolyte balance, cardiovascular regulation, and digestive health. It interacts with the body by supporting gastrointestinal motility, electrolyte homeostasis, and cardiovascular function. While there are no direct pharmacological targets, the effects are mediated through nutrient absorption and metabolic pathways. The nutrients in banana puree, such as potassium and fiber, are readily absorbed or utilized in the gut, contributing to its overall health benefits.

Side effects

Banana puree is generally safe when consumed in typical dietary amounts, but caution is advised in scenarios involving high potassium intake. Common side effects are rare, but excessive intake may cause gastrointestinal discomfort due to the fiber content. Uncommon side effects include the potential for mild bloating or gas in sensitive individuals. Allergic reactions are rare. The high potassium content may interact with potassium-sparing diuretics or ACE inhibitors. Patients with hyperkalemia or severe kidney impairment should limit their intake. Infants require volume control to avoid excess potassium, and diabetic individuals should monitor their carbohydrate intake. It is important to be mindful of these considerations to ensure safe consumption.

Dosage

For thickening purposes, banana puree volumes vary by milk type but should not exceed 15% of the feeding volume to maintain potassium safety. Optimal dosage ranges for supplementation have not been definitively established; dietary intake should be consistent with general banana consumption guidelines. The maximum safe dose is limited by the potassium content, as excessive intake may risk hyperkalemia. Banana puree can be administered with meals or as part of feeding formulations. The puree form is preferred for thickening and ease of digestion. No special cofactors are required for nutrient absorption, which is enhanced by normal digestion.

FAQs

Is banana puree safe for infants with feeding difficulties?

Yes, when used as a thickener within recommended volume limits (≤15% of feeding volume) to avoid excess potassium intake, it is considered safe and effective.

Can people with diabetes eat banana puree?

Yes, in moderation, considering the carbohydrate content and its potential impact on glycemic control. Monitoring blood sugar levels is advisable.

Does banana puree help with digestion?

Yes, the fiber and water content in banana puree can promote regular bowel movements and support healthy digestive function.

Are there risks of high potassium from banana puree?

Yes, excessive intake can lead to hyperkalemia, especially in vulnerable populations such as infants or individuals with kidney impairment. Moderation is key.

Research Sources

https://pubmed.ncbi.nlm.nih.gov/39508300/ – This clinical feasibility study on hospitalized infants with dysphagia found that banana puree effectively thickened infant formula and human milk to safe IDDSI levels. The study recommended limiting banana puree to 15% of feeding volume to avoid excess potassium intake. While the study was peer-reviewed, it had a small sample size and focused specifically on an infant population, lacking long-term outcome data.
https://www.medicalnewstoday.com/articles/271157 – This review article summarizes the nutritional benefits of bananas, highlighting their provision of fiber, potassium, and antioxidants that support heart health, blood pressure regulation, digestive health, and glycemic control. The review draws from multiple studies and authoritative guidelines, providing a comprehensive overview of banana's nutritional advantages. However, it generalizes from whole fruit data and is not specific to banana puree.
https://www.mdpi.com/1420-3049/27/10/3049 – This study evaluated the sensory properties of smoothies containing banana puree and found that they scored higher in sensory desirability among consumer panels. The findings support the acceptability of banana puree in functional foods. However, the study is limited by its subjective sensory data and lack of clinical outcomes.
