Why Jackfruit is Bad for Humans: Risks and Side Effects You Need to Know

If you’re like most health conscious eaters, you’ve probably heard that jackfruit is a superfood. It’s been touted as an important source of protein, a good source of fiber, and a tasty, versatile meat alternative. However, what most people don’t know is that jackfruit can be quite harmful to your health. That’s right – despite its status as a trendy “superfruit,” jackfruit can actually be bad for you.

Jackfruit is often used as a meat alternative in vegan and vegetarian diets because of its texture and flavor. However, consuming too much of it can lead to several health problems. Despite being high in fiber and vitamins, jackfruit can lead to digestive issues like bloating, gas, and diarrhea. Additionally, consuming overripe jackfruit can cause hypoglycemia, which can lead to dizziness, confusion, and even seizures. So, while it may seem like a healthy option, it’s important to be mindful of how much jackfruit you’re consuming, and to pay attention to any adverse reactions your body might be having.

While it’s true that jackfruit has some potential health benefits, it’s important to remember that everything should be consumed in moderation. Overconsumption of jackfruit can lead to serious health problems, so it’s essential to be aware of the risks. In the end, it’s up to each individual to decide whether or not jackfruit is worth adding to their diet, but it’s important to weigh the pros and cons before making any decisions.

Is Jackfruit Harmful to Humans?

Jackfruit has been a staple food in many cultures for centuries. However, there are concerns about its safety for human consumption. Here, we’ll look at some of the reasons why jackfruit might not be the best food choice.

Potential Allergies

  • Jackfruit is a member of the mulberry family, which means it contains similar proteins to other fruits like kiwi, figs, and papayas.
  • Individuals with allergies to these fruits may experience a range of symptoms including hives, swelling, and, in rare cases, anaphylaxis.
  • It’s important to note that jackfruit allergies are rare, and in many cases, those with fruit allergies can still consume it safely.

Blood Sugar Concerns

Jackfruit is a relatively high-carbohydrate fruit and contains naturally occurring sugars. This can pose a problem for individuals with diabetes or those trying to manage blood sugar levels.

One cup of jackfruit contains around 40 grams of carbohydrates, and while it’s a good source of fiber, it’s still essential to monitor overall carbohydrate intake. People with diabetes may need to limit or avoid jackfruit to maintain healthy blood sugar levels.

Possible Digestive Issues

In some cases, jackfruit may cause digestive issues such as gas, bloating, and diarrhea. This can be due to the high fiber content of the fruit, which can be difficult for some people to digest.

It’s important to note that these symptoms aren’t common, and most people can eat jackfruit without experiencing any adverse effects. Nevertheless, if you’re new to eating jackfruit, it’s best to start with small amounts and gradually increase your intake.

Nutrient Profile

While there are some concerns about eating jackfruit, it’s still a nutrient-dense food that can provide many health benefits. It’s an excellent source of vitamin C, potassium, and dietary fiber. Jackfruit also contains antioxidants that can help protect against cell damage and disease.

Nutrient Amount per Cup (165 grams)
Calories 157
Carbohydrates 40 grams
Dietary Fiber 6 grams
Protein 2.8 grams
Fat 0.6 grams
Potassium 739mg

Overall, jackfruit can be a healthy and delicious addition to your diet. However, it’s important to be aware of potential allergies, blood sugar concerns, and digestion issues before consuming it in large amounts.

Allergic Reactions and Jackfruit Consumption

While jackfruit has gained popularity as a vegan meat alternative due to its meat-like texture, it may not be suitable for everyone. In fact, some individuals may experience adverse reactions after consuming jackfruit. Allergic reactions, in particular, are a cause for concern when it comes to jackfruit consumption.

  • Allergy to latex: If you have a latex allergy, you may want to steer clear of jackfruit. The fruit contains latex, which can trigger an allergic reaction in sensitive individuals. Symptoms of a latex allergy can range from mild to severe and may include hives, itching, swelling, difficulty breathing, and anaphylaxis. If you experience any of these symptoms after consuming jackfruit, seek medical attention immediately.
  • Cross-reactivity: Some people who are allergic to certain foods may also experience cross-reactivity with jackfruit, meaning their body may mistake the proteins in jackfruit for the proteins in other foods they are allergic to. For example, individuals with a birch pollen allergy may experience cross-reactivity with jackfruit due to the fruit’s similarity to other birch pollen-related foods like apples and kiwis. Symptoms of cross-reactivity can vary but may include itching, swelling, and respiratory problems.
  • Intolerance: While not a true allergy, some individuals may experience digestive issues after consuming jackfruit, including bloating, gas, and diarrhea. This may be due to the high fiber content of jackfruit, which can be difficult for some people to digest.

Overall, if you have a latex allergy or are allergic to specific foods, it’s best to exercise caution when it comes to jackfruit consumption. If you experience any adverse reactions after consuming jackfruit, stop eating it immediately and seek medical attention if necessary.


Despite its many health benefits and versatility in cooking, jackfruit may not be the best choice for everyone. Those with latex allergies or cross-reactivity to specific foods should be cautious when consuming jackfruit to avoid potential allergic reactions. Additionally, some individuals may experience digestive issues due to the fruit’s high fiber content. However, for those who can tolerate it, jackfruit can be a delicious and nutritious addition to a plant-based diet.

The Effect of Jackfruit on Blood Glucose Levels

Jackfruit is a tropical fruit that has been gaining popularity in recent years due to its unique texture and flavor. However, some people claim that jackfruit may not be so good for human health. One of the concerns that have been raised is the effect of jackfruit on blood glucose levels.

  • Jackfruit is high in carbohydrates, with 23 grams per 100 grams of edible flesh. Carbohydrates are broken down into glucose in the body, which can cause a spike in blood sugar levels.
  • One study found that consuming jackfruit increased blood glucose levels in healthy adults. The participants consumed 300 grams of jackfruit, and their blood glucose levels increased by 5.8 mmol/L two hours after consumption.
  • Another study, conducted on rats, found that jackfruit extract reduced blood glucose levels. However, it is important to note that animal studies cannot always be directly applied to humans.

Overall, while some studies suggest that jackfruit may have a negative effect on blood glucose levels, more research is needed to fully understand the impact of jackfruit on human health.

Study Participants Findings
One study Healthy adults Increased blood glucose levels after consuming 300 grams of jackfruit.
Another study Rats Reduced blood glucose levels with jackfruit extract.

If you have diabetes or are watching your blood sugar levels, it is best to consume jackfruit in moderation and monitor your glucose levels after consumption.

Potential Digestive Discomfort from Jackfruit Consumption

While jackfruit is a nutritious and delicious fruit, consuming it can come with some potential digestive discomforts that are worth noting, especially for those with digestive issues or sensitivities. Here are some of the common digestive issues that can arise from jackfruit consumption:

  • Flatulence: Jackfruit is high in fiber, which can be difficult for some people to digest, leading to flatulence or bloating.
  • Diarrhea: Eating too much jackfruit can cause diarrhea in some people, especially those with digestive issues such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD).
  • Abdominal Pain: The high fiber content in jackfruit can be hard on the digestive system, leading to abdominal pain and discomfort in some individuals.

If you are new to eating jackfruit, it is best to start with small quantities and gradually increase as your body gets used to it. Additionally, it is important to drink plenty of water and eat a balanced diet when consuming jackfruit to help ease any potential digestive discomfort.

Digestive Issue Possible Cause
Flatulence High fiber content
Diarrhea Overconsumption or digestive issues
Abdominal Pain High fiber content

Overall, while jackfruit is a nutritious and tasty fruit, consuming it can lead to potential digestive discomforts. If you have digestive issues or sensitivities, it is important to consume jackfruit in moderation and consult with your healthcare provider if you experience any adverse symptoms.

Jackfruit as a Possible Foodborne Illness Carrier

Jackfruit is a popular fruit known for its numerous health benefits. However, it is essential to be cautious while consuming jackfruit as it is a possible foodborne illness carrier.

Foodborne illnesses are caused by consuming food contaminated by bacteria, viruses, parasites, or toxins. The factors that make jackfruit a possible carrier of foodborne illnesses are:

  • External Contamination: Jackfruit’s thick and rough skin is known to harbor pathogens such as Salmonella and E. coli. These bacteria can contaminate the fruit during handling and transport.
  • Cross-Contamination: Cross-contamination occurs when pathogens from one food item come into contact with another. Jackfruit can cross-contaminate other foods either directly or indirectly. Direct contamination can occur when juices from jackfruit come into contact with other foods, and indirect contamination can occur when pathogens transfer through hands, surfaces, or utensils.
  • Inadequate Cooking: Jackfruit is mostly consumed in its raw or unripe form, and this can pose a significant risk of foodborne illnesses. The fruit should be cooked adequately to kill all the bacteria and viruses that may be present.

Additionally, infected jackfruit can cause severe gastrointestinal issues such as diarrhea, cramping, and vomiting.

It is crucial to follow proper food safety practices while handling and consuming jackfruit. Some of these practices include washing hands thoroughly before and after handling the fruit and cooking it adequately, especially if it is consumed raw or unripe.

In conclusion, while jackfruit has numerous health benefits, it can still pose a risk to humans as a possible foodborne illness carrier. It is necessary to be aware of this and take necessary precautions to prevent any health risks associated with consuming the fruit.

Foodborne Pathogen Symptoms
Salmonella Fever, diarrhea, abdominal cramps, vomiting
E. coli Diarrhea, abdominal cramps, blood in the stool
Staphylococcus Aureus Nausea, vomiting, abdominal cramps, diarrhea

Note: The table shows some of the common foodborne pathogens that can contaminate jackfruit and their associated symptoms.

Jackfruit Consumption and Diabetes Risk

While jackfruit may be a popular vegan meat alternative, its consumption may not be suitable for everyone. In particular, individuals with diabetes should be cautious when consuming this fruit due to its high glycemic index.

  • The glycemic index (GI) is a measure of how quickly carbohydrates in food are absorbed and raise blood sugar levels.
  • Foods with a high GI value (above 70) are quickly absorbed and cause blood sugar levels to spike, which is problematic for individuals with diabetes.
  • Jackfruit has a GI value of around 75, making it a high GI food.

This means that consuming jackfruit can cause a rapid increase in blood sugar levels, which can be dangerous for individuals with diabetes. In fact, a study published in the Journal of the Academy of Nutrition and Dietetics found that consuming jackfruit significantly increased blood sugar levels in individuals with type 2 diabetes.

However, this does not mean that jackfruit is completely off-limits for individuals with diabetes. Consuming the fruit in moderation and in combination with other low GI foods can help mitigate the spike in blood sugar levels.

Low GI foods High GI foods
Green leafy vegetables Potatoes
Berries Bananas
Whole grains White bread

In addition, it is important for individuals with diabetes to monitor their blood sugar levels regularly and consult with a healthcare professional before consuming jackfruit or any other high GI foods.
