It's probably a translation lapse into English. Gula is close to its latin root, and concerns the very act of eating in an intemperate way: that's gluttony in English. Greed also describes excess, but is more concened with desire and acquisition. Food is but a subset target of greed - in this case describing the desire for food and its acquistion rather than the way it is consumed.

I'm not trying to teach granny to suck eggs! Just pointing out that while there is a clear distinction between the two sins in English, UK users of the language tend to conflate the notions of gluttony and greed in everyday usage. This conflation can manifest itself in the way translations from other languages are handled.

In a similar way, English users generally fail to distinguish, in language terms, between jealousy and envy - a distinction quite clear to most native speakers of Portuguese.
