There are many afctors that an influence a person's "ideal" nutritional habits. What you're saying is that a marathon runner living in Nigeria has the same nutritional needs as a Hindu living on sri Lanka has the same nutritional needs as an accountant living in New York City. That's obviously not true, for a variety of reasons.
As for sugared sodas, it's a matter of a person's other habits. You're making it sound like a healthy person can't drink soda and remain healthy. Our body is designed to deal with a lot of things; if you're fairly active, your body can take in many calories of sugar and use them as fuel instead of converting them to lipids. You don't really know what GT's lifestyle is like, so it's really hard for you to make absolute statements about his diet. Do you think a nutritional counselor (a good one, anyway) would give everyone the same advice because "When it comes to general physiology and health, humans are pretty much the same the world over"? Their jobs would be pretty pointless, wouldn't they!
