OK, you felt sick, after you had an energy bar, 30 minutes into a ride. That's not a lot for breakfast and maybe my question should have included: "What did you have for dinner the night before?"
"And I rode fine the morning I ate those meals."
What meals? The bacon, egg, etc?
"I had a banana or breakfast that day."
I'm sorry, I'm a little confused. How does the banana figure in?
If you're getting the bonk - typically that means you become suddenly weak on your ride - it means you're out of energy. If you didn't have enough food the night before (and only a Clif bar in the morning), then yes, your issue is diet or perhaps even hydration related.
As for your very low blood pressure reading - this is starting to sound like an episode from House - didn't the nurse take it a second time to validate the numbers? Dehydration could suggest why you feel sick, and your low blood pressure. Maybe the question should be "How much do you drink?" not about what you eat or don't eat.
