A method for reducing the likelihood of developing liver cancer in an individual diagnosed with non-alcoholic fatty liver disease that involves providing an individual with an effective amount of a composition of bacteria modified using a Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-associated system (CRISPR-Cas) or Clustered Regularly Interspaced Short Palindromic Repeats from Prevotella and Francisella 1 (CRISPR/Cpf1) system so that the bacteria is able to produce a therapeutically effective amount of anti-bodies to oxidized low density lipoprotein, with the modified bacteria preferably being from the Lactobacillus, Bifidobacterium, and Streptococcus species; and most preferably including L. reuteri bacteria modified using CRISPR-Cas and/or Cpf1 systems so that it is able to survive the conditions in the duodenum and jejunum of the small intestine of a human.
