Parasites, such as ectoparasites, helminths, and protozoans, are microorganisms that need a host to survive and multiply. Parasites are present in some foods, contaminated water, feces, soil, and the environment. Taking precautions to reduce the risk of parasitic infections is highly beneficial, as about one-fourth of the world population is likely infected with intestinal parasites.
Some claims state that bananas help eliminate parasites. This article explores the evidence-based abilities of natural remedies, including bananas and their components, to kill parasites within the body.

Understanding Parasitic Infections
Parasites are tiny worms or other organisms that can live and multiply inside the human digestive tract. They may enter the body in numerous ways, including through exposure to feces, water contaminated with parasites, and foods containing parasites.
Examples of parasites include protozoa (single-celled parasites), helminths (parasitic worms), and ectoparasites (spider-like bugs that burrow in the skin).
Symptoms of a Parasitic Infection
Symptoms of parasitic infections in humans include:
- Nausea
- Vomiting
- Diarrhea
- Muscle aches
- Gas
- Bloating
- Unexplained weight loss
- Abdominal pain
- Chills
- Fever
- Increased appetite
- Insomnia
- Skin rash
- Weakness
- Fatigue
These or similar symptoms may not appear immediately but develop after parasite exposure.
Risk Factors
Sources of parasites that may cause an infection include:
- Consuming undercooked or raw fish or meat
- Eating unwashed vegetables and fruits
- Consuming raw watercress or other raw aquatic plants
- Drinking unpasteurized juices or milk
- Exposure to contaminated water, food, blood, feces, or soil
- Sexual contact
- Contaminated bug bites
- Weakened immune system
- Poor hand washing before drinking or eating
- Infrequent bathing or showering
- Living in tropical, subtropical, or other warm, humid climates
Complications that may result from parasitic infections include dehydration, organ damage, malnutrition, anemia, pancreatitis, appendicitis, and gastrointestinal (GI) problems. For example, organ damage might develop if a tapeworm travels to the heart, brain, eyes, lungs, or liver.
The Claim: Bananas as a Remedy for Parasites
Do bananas kill parasites? Some nutritious foods have been shown to help eliminate harmful parasites from the digestive tract. Examples of foods and supplements that may reduce intestinal parasites include:
- Pumpkin seeds
- Raw garlic
- Pomegranate
- Papaya seeds
- Carrots
- Beets
- Pure honey
- Avocados
- Soybeans
- Fiber
- Digestive enzymes
- Probiotics
- Zinc
- Vitamin C
- Anise
- Oregon grape
- Wormwood
- Black walnuts
- Curled mint
- Barberry
- Goldenseal
- Turmeric
- Aqueous leaf extracts
- Oregano oil
- Cloves
- Extracts from banana stems, leaves, and peels
One reason bananas might help kill parasites is due to the fiber, prebiotic, and micronutrient content of these nutrient-dense fruits and extracts sourced from their non-edible parts.
Nutritional Profile of Bananas
The nutritional profile of one medium banana is as follows:
- Calories: 105
- Protein: 1 gram
- Carbohydrates: 27 grams
- Fiber: 3 grams
- Dietary fat: 0 grams
- Magnesium
- Manganese
- Vitamin C
- Phosphorus
- Potassium
- Folate
- Vitamin B6
The potential health benefits associated with bananas are abundant and include:
- Chronic disease prevention
- Improved digestive health due to prebiotics
- Enhanced immunity
- Sleep and appetite regulation
- Improved metabolism
- Lower blood pressure
- Enhanced organ health
Because bananas are a source of prebiotics, they help support probiotics (healthy gut bacteria) production.
Scientific Evidence on Bananas and Parasites
Research shows that probiotics have antiparasitic properties. While bananas typically are not on the list of foods that kill parasites, one study showed that ground banana plant leaf and pseudostem extracts contain antimicrobial activity against food-borne pathogens and infections.
Findings from another study confirmed that banana leaf and stem extracts have antimicrobial properties.
Animal studies have shown similar results, suggesting that banana extracts help reduce gastrointestinal parasites, but more research is needed.
Researchers studying the effects of banana peels found that tannins in banana peel extract possess antimicrobial activity, which may inhibit gram-positive bacteria and the growth of food-poisoning bacteria.
However, further research shows that bananas, mangos, tomatoes, green peppers, and other vegetables may be sources of parasitic contamination. This is particularly true in regions that use natural fertilizers. Nearly 4% of bananas analyzed in a separate study showed contamination with at least one type of parasite. This emphasizes the importance of thoroughly washing fruits and vegetables before consumption.
Bottom line: Comprehensive human studies regarding bananas' ability to kill parasites are limited. More research is needed to determine if bananas can kill parasites and help treat parasitic infections. However, the prebiotics in bananas appear to provide antiparasitic benefits, and the leaves, peels, and stems may offer additional antimicrobial advantages.
Comparative Analysis with Other Antiparasitic Foods
Compared to bananas, more extensive research exists in support of these antiparasitic foods:
- Garlic and onions: Studies show that these two foods and their extracts have known antiparasitic and antimicrobial properties.
- Papaya seeds: Researchers found that the fatty acids in papaya seeds can reduce parasites.
- Pumpkin seeds: Studies show that pumpkin seed extract helps manage gastrointestinal nematode infections.
- Barberry: Researchers suggest that barberry root is helpful for treating parasitic infections.
- Parasite-cleansing natural supplements: Antiparasitic supplements to consider include black walnut, wormwood, clove, garlic, and oregano oil.
- Other foods and supplements: Researchers found antiparasitic activity associated with turmeric, avocados, soybeans, aqueous leaf extracts, and more. Beets, carrots, pure honey, probiotics, and pomegranate also show promising potential.
While these foods are not necessarily more effective at killing parasites than bananas, more research supports the use of the above antiparasitic foods.
Because no specific guidelines and dosages exist for natural remedies to treat parasitic infections, individuals should consult with their healthcare provider for a personalized care plan and routine monitoring to determine the effectiveness of natural antiparasitic remedies.
Medical Treatments for Parasitic Infections
In addition to foods and supplement use for eliminating gastrointestinal parasites, conventional antiparasitic treatments are also available, including:
- Antiparasitics
- Antifungal medications
- Antibiotics
Medications can effectively eliminate parasites by stopping parasite growth, paralyzing them, or killing them or their eggs.
Homeopathic medicine options for intestinal parasites include:
- Podophyllum
- Spigelia
- Cuprum oxydatum nigrum
- Sabadilla
- Indigo
- Teucrium
- Cina
- Stanum
Some individuals benefit from combining various medications or supplements to cure parasitic infections.
Providers should tailor treatment plans to match an individual’s specific diagnosis and unique situation. They might first try natural remedies to prevent or treat parasites and move on to medications as needed.
Lab Testing for Parasites
Common laboratory tests used to diagnose parasitic infections include:
Stool Tests
- Comprehensive Stool Analysis by Access Med Labs
- Comprehensive Stool Analysis by Mosaic Diagnostics (formerly Great Plains)
- GI Effects® Comprehensive Profile - 3 day by Genova Diagnostics
- Comprehensive Stool Analysis + Parasitology - 3 Day by Doctor's Data
- GI-MAP by Diagnostic Solutions
Blood Testing
- Blood Parasite Smear by Access Med Labs
Other Diagnostic Tools
Individuals may need multiple tests for a healthcare provider to interpret the results effectively, make an accurate diagnosis, and customize a highly effective treatment plan.
Integrating Natural Remedies with Conventional Treatments
Combining natural remedies with conventional medicines may be a helpful solution for treating intestinal parasites. Natural remedies can also help prevent parasitic infections.
However, some parasite-reducing dietary supplements interact with certain medicines. Therefore, it is important for individuals to consult with a healthcare provider before trying natural remedies. They should do so only under medical supervision along with routine lab testing, particularly if they have another medical diagnosis or take prescription medications.
