My friend Katy is on a diet (The Perfect 10 Diet) which cuts out refined sugars and grains. I don't know all of the details, but I have another friend who has done the same thing and it has been really wonderful for her family. She said it took her a year to really cut it all out, but it was worth it.

We are exploring the idea of getting rid of sugar in our home. It's a big undertaking. Pray for us to be wise.
