Manuka honey, a unique type of honey produced in New Zealand by bees that pollinate the manuka bush (Leptospermum scoparium), has gained global recognition for its potential health benefits. These benefits are attributed to its high concentration of methylglyoxal (MGO), a compound known for its antibacterial properties. While many people can safely enjoy manuka honey and experience its potential advantages, it’s crucial to understand that it’s not suitable for everyone. This article will explore the specific groups of individuals who should avoid or exercise caution when consuming manuka honey.
Understanding Manuka Honey and Its Potency
Manuka honey differs significantly from regular honey. Its unique properties stem from the presence of MGO, along with other compounds like leptosperin and dihydroxyacetone (DHA). The UMF (Unique Manuka Factor) grading system helps consumers identify the potency of manuka honey, with higher UMF values indicating a greater concentration of these beneficial compounds. This potency, while advantageous for some, can pose risks for others.
The Role of Methylglyoxal (MGO)
MGO is the key ingredient that differentiates manuka honey. It is formed from DHA, which is naturally present in the nectar of the manuka flower. MGO is responsible for most of manuka honey’s non-peroxide antibacterial activity. However, its high concentration can also be problematic in certain individuals. The higher the MGO rating, the more potent the antibacterial effect, and the greater the potential for adverse reactions in susceptible individuals.
Individuals with Diabetes or Insulin Resistance
One of the primary groups who should exercise extreme caution with manuka honey is individuals with diabetes or insulin resistance. Honey, in general, is a concentrated form of sugar, primarily glucose and fructose. Manuka honey, despite its health benefits, is no exception.
The Impact on Blood Sugar Levels
Consuming manuka honey can lead to a rapid spike in blood sugar levels. This is because the sugars are quickly absorbed into the bloodstream. For individuals with diabetes, who have difficulty regulating blood sugar, this can be particularly dangerous. Uncontrolled blood sugar can lead to a range of complications, including nerve damage, kidney damage, and cardiovascular problems.
Interactions with Diabetes Medications
Furthermore, the sugar content of manuka honey can interfere with the effectiveness of diabetes medications, such as insulin and oral hypoglycemic agents. It can make it more challenging to maintain stable blood sugar levels, potentially requiring adjustments to medication dosages. Anyone with diabetes considering using manuka honey should first consult with their healthcare provider to discuss the potential risks and benefits.
Glycemic Index and Glycemic Load
It’s important to consider the glycemic index (GI) and glycemic load (GL) of manuka honey. While the exact GI and GL can vary depending on the specific batch and composition, honey generally has a moderate to high GI and GL. This means it can cause a relatively rapid rise in blood sugar levels compared to other carbohydrates. People with diabetes need to carefully monitor their carbohydrate intake, and manuka honey should be factored into their calculations.
Individuals with Honey Allergies
Individuals with known allergies to honey, pollen, or bees should avoid manuka honey. Allergic reactions to honey can range from mild to severe, and in some cases, can be life-threatening.
Understanding Honey Allergies
Honey allergies are often triggered by the presence of pollen from various plants. Because manuka honey is derived from the manuka bush, it can contain pollen from this plant, as well as other pollens that bees may have collected. The proteins in the honey can also trigger an allergic response.
Symptoms of Allergic Reactions
Symptoms of a honey allergy can include hives, itching, swelling of the face, lips, or tongue, difficulty breathing, wheezing, nausea, vomiting, diarrhea, and dizziness. In severe cases, anaphylaxis can occur, which requires immediate medical attention. Anaphylaxis is a severe allergic reaction that can cause a sudden drop in blood pressure, difficulty breathing, and loss of consciousness.
Cross-Reactivity
Individuals with allergies to bee venom or other bee products may also be at an increased risk of being allergic to manuka honey due to cross-reactivity. This means that the proteins in bee venom or bee products are similar enough to the proteins in honey that the immune system can recognize them as the same, triggering an allergic reaction.
Infants Under One Year Old
Infants under one year of age should never be given manuka honey or any other type of honey due to the risk of infant botulism. Infant botulism is a rare but serious illness caused by spores of the bacterium Clostridium botulinum, which can be found in honey.
The Risk of Infant Botulism
Infants have immature digestive systems that are not yet capable of inhibiting the growth of Clostridium botulinum bacteria. If an infant ingests honey containing these spores, the bacteria can multiply in their intestines and produce a toxin that can cause paralysis.
Symptoms of Infant Botulism
Symptoms of infant botulism can include constipation, weak cry, poor feeding, lethargy, and muscle weakness. In severe cases, it can lead to respiratory failure and death.
Prevention is Key
The Centers for Disease Control and Prevention (CDC) and other health organizations strongly advise against giving honey to infants under one year of age to prevent infant botulism. The risk is minimal in older children and adults because their digestive systems are more mature and can inhibit the growth of the bacteria.
Individuals with Certain Medical Conditions
Certain medical conditions may make manuka honey consumption inadvisable. Consultation with a healthcare professional is paramount before incorporating it into the diet.
Compromised Immune Systems
Individuals with compromised immune systems, such as those undergoing chemotherapy or those with HIV/AIDS, should exercise caution when consuming manuka honey. While manuka honey has antibacterial properties, it is still a food product and can potentially contain bacteria or other microorganisms that could cause infection in individuals with weakened immune systems.
Gastrointestinal Issues
Manuka honey may not be suitable for individuals with certain gastrointestinal issues, such as irritable bowel syndrome (IBS) or small intestinal bacterial overgrowth (SIBO). The high sugar content of honey can exacerbate symptoms such as bloating, gas, and diarrhea.
Weight Management Concerns
Because manuka honey is high in calories and sugar, individuals who are trying to lose weight or manage their weight should consume it in moderation or avoid it altogether. The excess calories from honey can contribute to weight gain.
People Taking Certain Medications
Manuka honey, due to its bioactive components, may interact with certain medications. Consulting a healthcare provider or pharmacist is essential to assess potential risks.

Chemotherapy Drugs
Some studies suggest that manuka honey may interact with certain chemotherapy drugs. While some research indicates potential benefits, such as reducing side effects, it’s crucial to discuss the use of manuka honey with an oncologist before incorporating it into the diet during chemotherapy.
Medications Metabolized by the Liver
Because the liver metabolizes many drugs, and manuka honey contains compounds that can affect liver enzymes, there is a potential for interaction with medications processed by the liver. Individuals taking such medications should consult with their healthcare provider.
Pre- and Post-Surgical Patients
Given its potential effects on blood sugar and blood clotting, manuka honey consumption should be carefully considered before and after surgical procedures.
Pre-Surgical Considerations
It is generally recommended to avoid consuming manuka honey in the days or weeks leading up to surgery. This is because of its potential to affect blood sugar levels and blood clotting. Maintaining stable blood sugar levels is important during surgery, and the potential anticoagulant properties of manuka honey could increase the risk of bleeding.
Post-Surgical Considerations
After surgery, it’s also important to be cautious about consuming manuka honey. The body is in a healing state, and controlling blood sugar and preventing infection are critical. While the antibacterial properties of manuka honey may be beneficial for wound healing, it’s essential to consult with a surgeon or healthcare provider before using it.
The Importance of Moderation and Consultation
Even for individuals who can safely consume manuka honey, moderation is key. Excessive consumption can lead to unwanted side effects, such as weight gain and elevated blood sugar levels.
Consulting with a Healthcare Professional
Before incorporating manuka honey into your diet, especially if you have any underlying health conditions or are taking medications, it’s essential to consult with a healthcare professional. They can help you assess the potential risks and benefits and determine if manuka honey is right for you.
