🌿 Overview
MSG (monosodium glutamate) is a chemical flavor enhancer added to many processed foods and used widely in Chinese and Japanese restaurants. It is also sold as a meat tenderizer under the brand name Accent. MSG is increasingly added to many processed foods under other names — often without being clearly identified on the label. Hidden MSG names include: hydrolyzed vegetable protein, autolyzed yeast, calcium caseinate, sodium caseinate, whey, vegetable broth, malt extract, smoke flavoring, textured vegetable protein. MSG manufacturers admit that it creates dependency (addicts consumers to foods). A lack of vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → B6 increases sensitivity to MSG.
Common signs
- Headache, flushing of the face, tingling and burning sensations, weakness, sweating, chest discomfort or tightness.
- Usually appears 15–30 minutes after eating MSG-containing food.
- Also called 'Chinese Restaurant Syndrome' when occurring after Chinese restaurant meals.

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Whole, unprocessed foods. No packaged or processed foods with ambiguous ingredient lists. Cook at home using fresh ingredients. Supplement B6 (50 mg daily).
⚖️ Good to know
- Pregnant and lactating women should not exceed 100 mg total of B6 daily.
- MSG is not the only excitotoxin — aspartame (NutraSweet/Equal), hydrolyzed vegetable protein, and certain other additives act similarly.
- Those with severe reactions should carry information about their sensitivity and read all food labels carefully.
