More than 25% of people aged between 18 and 24 regularly choose not to have bacon on their full English, according to a survey by Glotech Repairs.
Anna Daniels, dietician and spokesperson for the British Dietetic Association, said: "With the growing emergence of social media, teens and adolescents are becoming increasingly aware of their eating habits.
"There is a worry that this can be taken to the extreme as a little bacon in a full English occasionally as part of a balanced diet would be perfectly harmless."
Last November, the World Health Organisation published a report linking consumption of processed meats such as bacon, hot dogs and sausages to increased chances of developing colorectal cancer.
Following a 17% slump following the report, the Agriculture and Horticulture Development Board said bacon sales had largely recovered.
However, they had still dropped by 4% since the report was released to the public.
Cereal was found by the survey to be the most popular breakfast among young Brits, with almost two thirds of those asked saying they typically ate it for breakfast followed by toast (just over 50%), porridge (roughly 35%) and eggs (22.6%).
Additionally, scrambled eggs are overtaking fried eggs among young people, the report said.
Ursula Philpot, of Leeds Beckett University, said: "There is a link between meats like bacon, which are cured and wrapped, and bowel cancer, which is why we ask people to avoid and reduce their consumption when possible."
