I think that the more specific, the better. This question is different from any career Q I have answered that mostly ask for short/long career goals. There is probably a reason for this...
But not too specific. There's a balance.
Saying that you want to be a analyst focused on blue-dye sublimination techniques at Goldman Sachs in their Midtown NYC office will come off as short-sighted. Saying you want to be a analyst focused in "CPGs" with an investment bank or private wealth management firm, will sound focused, but broad enough that your goals are achievable. Similarly saying you want to be an investment banker is too broad.
In your case, I'd suggest talking about the food and beverage industry (and be SURE to explain WHY this is an area you want to be in) - not just international marketing.
For instance: I want to be a brand manager with a CPG firm focused on the low-caloire food and beverage industry, or with ad agency in the same space. I want to do this because of.........
Which brings me to my last and equally boring point: if you have more than one goal, make sure they are reasonably related - i.e. brand manager at a CPG firm, or an advertising manager at an ad agency. Don't say "either an investment banker" or "management consultant" - for these are two entirely different paths, and anyway, only one of them is a good idea anyhow.
