From the Research
Monosodium glutamate (MSG) can have adverse health effects, particularly with high doses and repeated exposure, and its consumption should be limited to minimize the risk of embryotoxicity, teratogenicity, obesity, cardiotoxicity, hepatotoxicity, kidney toxicity, neurotoxicity, endothelial dysfunction, reproductive toxicities, alteration of lipid, and glucose metabolism 1.
Key Findings
- High doses and repeated exposure to MSG have been associated with various health problems, including obesity, cardiotoxicity, and neurotoxicity 1, 2.
- MSG can also affect lipid and glucose metabolism, leading to an increased risk of metabolic disorders 1, 3.
- Some natural products, such as Calendula officinalis, Curcuma longa, and Green Tea, may have protective effects against MSG-induced toxicity 4.
Recommendations
- Limit MSG consumption to minimize the risk of adverse health effects, particularly for individuals who are sensitive to MSG or have pre-existing health conditions 1, 2.
- Consider alternative flavor enhancers, such as herbs and spices, to reduce MSG intake 1.
- Further research is needed to fully understand the effects of MSG on human health and to establish safe consumption levels 2, 3.
Important Considerations
- MSG is widely used in food products, and its consumption can be difficult to avoid entirely 1, 2.
- Individuals who are concerned about MSG sensitivity or adverse health effects should consult with a healthcare professional for personalized advice 1, 2.
- More research is needed to understand the potential benefits and risks of MSG consumption, particularly in relation to obesity and metabolic disorders 3, 5.
