I don't agree it's unquantifiable in this instance -- the diet is intended to meet the standards outlined by the UK Food Standards organization [1]. Whether or not you agree with the standards is a valid point, but a separate issue.

His point is that while the government can write into law what they believe the definition of healthy to be, that doesn't necessarily make it biologically accurate.

I see your point, though, you're not going to get drawn into a debate on that definition since your project isn't about the "true definition" of healthy but rather it assumes that the nutrition guide is adequate.

"Healthy" is a subjective descriptor, it cannot be quantified. There's a reason it differs from person to person, nation to nation, health organization to health organization.

It can be quantified, and it was. You are just arguing for the sake of arguing. You not liking the definition of healthy that she specified does not mean it can not be specified.
