My wife and I don't know how to grocery shop anymore.

We used to.

We brought home food, cooked it, and the kids ate it usually.

Even though we only see the kids on weekends or breaks from college, they do stop by to fill their bellies.

Except it's getting harder for them to get filled up at our house.

It's not that we are doing anything differently, but Claire and Alek have changed their eating habits.

Not sure where we went wrong, but they have become health conscious. They are extremely particular about what they put in their bodies.

My wife and I will make meals, and sometimes they will make their own.

Or we ask what they want to eat and make that, which is usually healthier than what we would have cooked.

It's not unusual for Alek to come home, look through the cupboards and refrigerators several times before finding something that suits his diet.

He is trying to gain weight. Wish I had that problem. His diet is made up of a lot of protein: meat, fish, cheese, eggs, things like that.

He has turned his attention from baseball to weight lifting, which has resulted in him changing his major again, this time to exercise science, with an eye on becoming a nutritionist and possibly owning his own business that specializes in nutrition and supplements. Think GNC.

Claire, the runner, has always been a finicky eater.

When she was in high school, she could become a vegetarian in an instant, depending on what we were having for supper that night.

Now she, too, is particular about what she puts in her body.

Fruits, vegetables, eggs, pasta and a lot of salads are her favorites.

Occasionally, she will crave chocolate, like last weekend.

She made chocolate chip cookies, ate a couple and then left the rest to the two people who don't need to be eating them but we did.

It was Claire who got me to give up pop, and now she is trying to whip me into shape.

Maybe I should hire her as my personal chef.

It is something to watch your kids grow up and make the decisions they make.

It's not like we live in a fit country.

Now there is a report that a child's weight issue could be decided by the time they are 5, meaning by the time they enter school it may be too late to shape their eating habits.

Reports like that are scary because there will be some who decide a healthy lifestyle is predetermined at an early age, and there's no use trying to live healthy.

Claire and Alek learned later the benefits of being healthy. It's never too late.

It's a case of the kids setting a good example for the parents.
