Fact check: Msg (ajinomoto) is harmful

1. Summary of the results

The claim that MSG (ajinomoto) is harmful is not supported by scientific evidence. Multiple authoritative sources, including the FDA, have classified MSG as "generally recognized as safe" ^[1]. Scientific research has consistently shown that MSG is safe for all life-cycle stages, with the human body naturally metabolizing glutamate ^[2]. Double-blind studies have failed to find consistent adverse reactions ^[2].

2. Missing context/alternative viewpoints

Several important contextual points need to be considered:

• MSG is made from naturally occurring substances like glutamic acid, which is found in many common foods ^[1]
• While excessive use can be problematic, MSG itself cannot induce heart attacks or cause terminal illness ^[1]
• A small subset of people may experience what's called "MSG symptom complex," but these reactions are typically mild and short-lived, occurring only with very large doses ^[3]
• The substance has been "studied intensively for many years" under scientific scrutiny ^[4]

3. Potential misinformation/bias in the original statement

The widespread belief in MSG's harmfulness appears to have concerning origins:

• The anti-MSG sentiment largely originated from racial prejudice rather than scientific evidence ^[3]
• The controversy can be traced back to a 1968 letter speculating about symptoms, not rigorous scientific research ^[3]
• The topic remains "controversial" with arguments for and against its use, despite the lack of definitive evidence supporting harmful effects ^[4]

This case demonstrates how cultural biases and historical misconceptions can persist despite contradicting scientific evidence. Those who benefit from anti-MSG sentiment might include:

• Alternative food additive manufacturers
• "Clean eating" lifestyle brands
• Authors and influencers promoting MSG-free diets
