McDonald's Fries Secret: MSG Boosts Consumption by 40%
McDonald's fries have long been a topic of debate about their addictive nature. A study on rats found that they eat up to 40% more when MSG is present in their food, and this ingredient is also linked to reduced feelings of fullness.
The 'natural beef flavor' in McDonald's fries consists mainly of hydrolyzed wheat and hydrolyzed milk, which produces MSG. This means that even though there is no actual meat in the fries, they still contain a compound that can make people crave them more.
The study on rats suggests that this addictive quality is not just due to the taste or freshness of the fries, but rather the effects of MSG on our brains and stomachs.
