Researchers found a "significant link" between eating breakfast and performing above average on teacher assessment scores.
There was also a strong link between eating a healthy breakfast - such as cereal, bread, dairy or fruit - and doing well at school.
Andy Stockinger runs a breakfast club at St John's Church in Peasedown St John and told Premier's News Hour it's a "great way for the church to get involved in the community".
He said: "Through the club we've actually had parents come to church, so it's a wonderful opportunity for the church to get involved, to be a service to the community."
The study on around 5,000 pupils from more than 100 primary schools was led by a team at Cardiff University.
It involved asking pupils aged nine to 11 what they ate for breakfast and during the rest of the day, and following their educational progress six to 18 months later.
The team found that a good breakfast was strongly linked to performing above average on Key Stage 2 teacher assessments, while there was also a link for those pupils who carried on eating fruit and veg at other times of day.
Mr Stockinger added: "We take on some children that are not in a fortune enough position to have breakfast and it makes a big difference to their lives to be able to have something to eat and concentrate on their work rather than their stomach".
Dr Graham Moore, who worked on the study, said: "We analysed links between whether young people were eating breakfast and the quality of that breakfast.
"There's a significant association between eating breakfast and doing well, but there is also a link between a healthy breakfast and doing well.
"The odds of achieving an above average teacher assessment score were up to twice as high for those pupils who ate breakfast.
"The odds of scoring above average was between 50% and 100% higher if any breakfast was eaten."
