what other uni choices should i add? (population health)

my current grades are ABB which is the grade requirement for the 2 UCL courses I am interested in - Population Health Data sciences and Business and Health. But so far, these are my only 2 courses I have added to my ucas choices but i dont know what else to add, especially because I want to stick to London Universities only and i only want to add courses that are somewhat or either business/health related. Population Health Data Sciences is my first choice though as the data science part really interests me and I think it will be somewhat useful in the future (my PS is also tailored to it). Any suggestions/help/advice would be greatly apprecuated!
