If i had to choose from adequate nutrition that was unbalanced or inadequate nutrition that was balanced, which would be more harmful to my health?

Very hard to say: First of all, i'm not sure what you mean by "adequate" nutrition. If you mean sufficient calories in a diet, then the choice would be between sufficient calories but lack of proper nutrients vs. Insufficient number of calories but correct balance of nutrients. Both situations would have harmful consequences. Good health requires the right amount and composition of nutrients!
