The *topic* of these questions are largely in scope, but these types of questions themselves are generally very poor. There's nothing new here. Just refer back to:

**"Guidelines for Great Subjective Questions"** from [**Good Subjective, Bad Subjective**](http://area51.stackexchange.com/proposals/29912/system-administrators).

Asking "How Bad is Soda for You?" is no different (i.e. no better) than asking "Is the Canon SX220 a good camera?" on the Photography Stack Exchange.

For a question to be useful Q&A, there has to be a specific problem someone is trying to solve? This isn't about chit-chat and starting conversations. Food and nutrition questions are on topic if there's an actual, specific question about Physical Fitness involved.

The only one that came close was the *peanut butter* question. But the rest like  *"What's the deal with aspartame?"* — That not *Good Subjective* and certainly goes against the sentiments of: [Please avoid very broad, beginners' questions during the beta](http://meta.fitness.stackexchange.com/questions/6/please-avoid-very-broad-beginners-questions-during-the-beta).

But when closing questions asked in good faith, please take the extra time to leave comments *politely* explaining why those questions are not useful here. It's not always obvious that Stack Exchange is trying to rise above many of these discussions which are common among other forums. Let's not greet new users with contempt. Link to the above discussions, if that helps.
