Normandy
King Henry I of England loved eating lampreys, ignored his doctor's advice, consumed a large amount in Normandy in 1135, suffered food poisoning, and died shortly after.
Infact verdict: Mixed (51/100).
The claims about King Henry I's love for lampreys and his subsequent death are based on historical accounts, but the exact cause of his death remains uncertain. While it is documented that he enjoyed lampreys and ignored medical advice, the notion that he died from eating them is debated. Some sources suggest alternative medical causes for his death, such as a Listeria infection. The evidence supports the historical context but does not definitively prove the cause of death was lampreys.
