I wonder, sometimes, how we come to like some foods and dislike others. There are avoid foods that I naturally dislike. I think, "It's my body telling me that cucumbers are not good for me." But there are also avoid foods that I love, and turn away from only with the greatest degree of self discipline. I don't understand it.

I have noticed, that the longer I eat like an O, the more I seem to like the foods that are beneficial for me.

For most of my life I have not liked onions. I eventually learned to eat cooked onions, and since starting the BTD, grilled onions have become one of my favorite foods. But I still didn't like raw onion. If by mistake I crunched into a bit of chopped onion, I would gag. Many times I simply could not swallow it.

But I am changing. There are two Mexican restaurants near the school where my Darling Daughter and I can get a quick taco salad. One of them serves black beans - that's a big plus. Unfortunately, that restaurant also tops their salad with raw onions. Even if I ask them to leave off the onions, a few pieces always escape.

Last year I picked through the salad, looking for stray onions. A missed piece would greatly distract from my enjoyment of the meal. When school started this year, I noticed a peculiar thing. If I crunched an onion in the salad, nothing happened. I chewed it and swallowed it as if it were a piece of lettuce or carrot. Was I - after 54 years - learning to like raw onion?

Tonight we had a Middle School basketball game and an Elementary Christmas music concert to photograph, so we stayed late at school. DD went to pick up salads, and forgot to tell them no onions. As I began to eat, I was aware that there were lots of onions. But they didn't make me wince or gag. I ate them along with everything else.

I guess my tastes are changing. I can't think of a single Type O beneficial food that I flat out refuse to eat. I have gradually come to like the foods that are beneficial for me - even the ones I had disliked for 40 years.

Now, if I could just get DD to give mushrooms a fair trial…
