哈哈，赞一下你求真的精神！我同意ChatGPT关于MGO的大部分看法。MGO不是一个好东西，但少吃无妨。至于MGO到底是致癌还是抗癌，我觉得这个观点更准确：High MGO levels cause growth arrest in several types of cancer. Conversely, a lower increase in MGO concentrations can promote cancer growth。

謝謝博主的信息。我正好最近開始吃麥盧卡蜂蜜，趕緊去問了ChatGpt.這是問答：
Is methylglyoxal in Manuka honey with GMO 600+ high enough to be cytotoxic and carcinogenic？
Methylglyoxal in MGO 600+ Manuka Honey: A Look at the Science
The concentration of methylglyoxal (MGO) in Manuka honey with a rating of MGO 600+ is significant, indicating at least 600 mg of MGO per kg of honey. While MGO is a potent antibacterial compound and the key contributor to Manuka honey's unique therapeutic properties, concerns about its potential cytotoxicity (harm to cells) and carcinogenicity (cancer-causing potential) at high levels are valid. However, current scientific understanding suggests that the consumption of MGO 600+ Manuka honey as part of a normal diet is unlikely to be cytotoxic or carcinogenic.
Here's a breakdown of the key factors to consider:
MGO Concentration and its Dual Role:
An MGO 600+ rating signifies a high concentration of methylglyoxal. This compound is indeed cytotoxic to bacteria, which is the primary reason for Manuka honey's effectiveness against infections. In laboratory studies, high concentrations of MGO have been shown to be damaging to various cell types.
However, the effect of MGO is dose-dependent. Research indicates that MGO can have a dual role, acting as both a pro- and anti-cancer agent depending on its concentration and the cellular context. While extremely high, isolated doses of MGO can be harmful, the levels found in Manuka honey are consumed in small amounts as part of a complex food matrix.
The Body's Defense Mechanisms:
The human body has natural defense mechanisms to detoxify reactive compounds like MGO. The glyoxalase system, present in cells, plays a crucial role in converting MGO into a less harmful substance, D-lactate. This system helps to prevent the accumulation of MGO to levels that would be broadly cytotoxic or carcinogenic from dietary sources like Manuka honey.
Context of Consumption:
It is important to consider the typical amount of Manuka honey consumed. A standard serving is one to two teaspoons (about 7-14 grams). In a single serving of MGO 600+ honey, the amount of ingested MGO would be in the range of 4.2 to 8.4 mg. This is a small fraction of the total dietary intake of MGO, which is also found in other foods and is produced endogenously in the body as a byproduct of metabolism.
In conclusion, while methylglyoxal is a reactive compound with cytotoxic potential at high concentrations in laboratory settings, the amount present in MGO 600+ Manuka honey is not considered to be at a level that would be harmful when consumed as part of a balanced diet. The body's natural detoxification processes and the small serving sizes typically ingested mitigate the potential risks. As with any food product, moderation is key.
So overall the benefit of Manuka honey with high MGO far outweighs the potential health concerns if I take one teaspoon daily?
Based on current scientific understanding, for the vast majority of healthy adults, the well-documented benefits of taking one teaspoon of high-MGO Manuka honey daily are generally considered to outweigh the potential health concerns.
