While manuka honey is celebrated for its antibacterial properties, new evidence suggests its high methylglyoxal content may carry risks. Recent research indicates that methylglyoxal could support tumour growth by helping cancer cells evade programmed cell death. This means cancer cells might survive longer, continue dividing, and potentially spread more aggressively.
“Some studies have shown that this type of honey can induce apoptosis in cancer cells, causing them to die,” explained Dr. Zev Schulhof, an oral and maxillofacial surgeon.
Bees produce manuka honey from the nectar of the manuka bush, native to New Zealand and southeastern Australia. Known for its rich flavour and health benefits, manuka honey is often used in skincare, wound dressings, and as a natural sweetener. Its antibacterial strength is measured by the unique manuka factor (UMF) rating, which is directly related to its methylglyoxal content.
However, a review in Frontiers in Oncology noted, “MGO can support tumour growth essentially through the evasion from programmed cell death and increased migration.”
As Dr Schulhof cautioned, “It’s important to note that manuka honey isn’t a substitute for treatments such as chemotherapy.” Until more is known, moderation in consumption is advisable, especially for those considering it for anti-cancer purposes.
