Healthy Bacteria??

So the other day, my stomach hurt and I was told to eat some yogurt. Supposedly yogurt helps with issues like stomach aches and misbehaving chihuahuas due to their helpful bacteria. Now at this point I thought why would I want to eat something with bacteria in it; the word bacteria pretty much just turns off my hunger sensor. So I was thinking why don't they just invent a new word for helpful bacteria or cultures, as the yogurt commercials call it? Something more appealing.... I have no ideas on this word but, I'm sure they could invent something and definitely sell more yogurt. It's kind of like the MRI's at the hospital. In my chemistry class, I learned that NMR is the same thing as MRI. Why the name change? Well NMR stands for Nuclear Magnetic Resonance and the medical population seemed to think that their patients would refuse to have this procedure done if they knew it includes the word nuclear. Politics are everywhere.
