Some marketing or consumption activities involve the (literal)

consumption of people – voluntarily or not. In one recent controversial incident, a man in Germany advertised on the internet to find someone who wanted to be killed and eaten

(we are not making this up). He actually found a willing volunteer and did just what he promised – and was jailed for manslaughter. If a person consents to be ‘consumed’ in some way, is this still an ethical problem? What of value is being exchanged here? Would it be different if a person ate part of themselves?
