Researchers at the Bristol University found a link between child’s diet before the age of three and his IQ.

Children eating junk food when they were three years old had a lower IQ in tests when they were eight.

The researchers could not change the tendency even after they tried to develop a special diet for children who got used to junk food, eurosmi website reported. The research was conducted among 14,000 children born around 20-15 years ago.  

The experts said they were not surprised to see such results.
