Did I tell you to get 20g a day? Was it 30? Hmmm....
It's okay to argue with people in positions of authority as long as people are respectful. That's how intelligent discussion comes about. Most of the time it comes off as being a dickface if the post is inflammatory or aggressive vs. "I think I disagree because this, what do you think?" Then again, most people these days take "I disagree" as "I think you're a moron", so you might just be onto something....
Anyway, no 60g isn't "better" than 20g...I think both are a little off. 35-55g is usually my range give or take and while I don't mind supplementing a little bit here and there, I think that misses the point of eating a "high fiber" diet. Vegetables are fine sources. 50g of carbs from greens is approx 25g of fiber....seems okay to me.
Anyway, corn bran kind of sucks at doing what fiber is good at doing, e.g. improving sugar metabolism, decreasing LDL, etc. Plus it's not really well tolerated either...
