I was just researching Grape Nuts Cereal. I may buy some when I go shopping this week. I love this cereal and I've got some interesting recipes I'd like to try that include it.
Ingredients: WHOLE GRAIN WHEAT FLOUR, WHEAT FLOUR, MALTED BARLEY FLOUR, SALT, DRIED YEAST, SOY LECITHIN. VITAMINS AND MINERALS: REDUCED IRON, NIACINAMIDE, ZINC OXIDE (SOURCE OF ZINC), VITAMIN B6, VITAMIN A PALMITATE, RIBOFLAVIN (VITAMIN B2), THIAMIN MONONITRATE (VITAMIN B1), FOLIC ACID, VITAMIN B12, VITAMIN D.
From the FAQ section, referencing cereal:
Cold - 30 grams/1 ounce/3/4 cup. Varieties with 3.0 - 4.9 grams are “good” sources of fiber. “High” fiber cereals have 5.0 grams of fiber or more per serving. Choose a cereal with enough fiber to be at least on the upper end of “good,” and make sure it has less than 8 grams of sugar per serving.
From the Kraft website, 1 serving is 7 grams fiber, 4 grams sugar, however that is for a 58 gram serving, 200 calories. So it looks like a 30 gram serving would just make the 3.0 gram cutoff for a good amount of fiber and is okay for sugar. Not sure about that second ingredient though "Wheat Flour". Does anyone eat this regularly? Any issues? Cereal ain't cheap, plus if I buy it, I will want to eat it, so thought I'd consult the chicks first.

First of all, even though the first ingredient is "whole grain wheat flour", that doesn't mean that it's 100% whole grain. And wheat flour is just a fancy name for white flour with a little whole wheat mixed in. 
I was thinking the exact same thing!
