This weekend, I was moonlighting at a small town hospital. The people in the area are for the most part simple folks; many live on farms, or have been in that community for generations.
I admitted an 83 year-old man who'd had a stroke. He hadn't seen a doctor in probably ten years, so in addition to treating his stroke I diagnosed him with hypertension and hyperlipidemia. He asked what he should be eating.
When I give diet advice, usually I don't use the word vegetarian, let alone vegan. "Lots of fruits and vegetables and whole grains. Stay away from animal products, like meat, eggs, or dairy."
His response: "Oh, vegetarian! My daughter is a vegetarian!"
"Yes," I said. "You should definitely have her help you out."
Never in a million years would I think this man or his family would have any concept of what a vegetarian is. I was pleasantly surprised.
