What is one example of a negative influence that could get in the way of him eating healthy foods?

A negative influence is that the parents are also not eating healthy and that kinda tells him that eating unhealthy food is not a bad thing for him.

Dis correct. the rest of the answers are definitely wrong.without the basic needs like food, shelter and love , one will remain trapped in trying to fulfil these needs first which means putting food on the table and struggling to pay bills. it is impossible to achieve self actualization when without the basic needs which is the base.
