Here I am with another link. This one explains soluble and insoluble fiber and gives examples of foods containing each one.
I have recently been eating lentils and they contain both. I bought some canned lentil soup, but since I am not much of a soup eater, I wasn't eating it often. Now I have been draining and rinsing the soup and using the lentils separately. Today, I put some in my cabbage/kale/onion concoction. I was thinking I could have a small cup of lentil soup before dinner each day, too. Right now I have a batch of vegetable soup in the refrigerator, and I think I will add some lentils to my bowl when I eat the soup. Can't add it to the whole batch because that would not please DH.
When we went to my sisters funeral DH could BARELY button the pants from his good suit, so I think he will be cutting back. LOL
