That's a myth. Fiber slows down an absorption but doesn't prevent it. Eat as much fiber as you wish
Webmd states that:
"Excess fiber can bind to iron, zinc, calcium, and magnesium and decrease their absorption. And studies have shown that fibers such as pectin and guar gum can reduce absorption of carotenoids, beta-carotein, lycopene, and lutein when consumed at the same time as a meal".
"When taken at the same time as medications, fiber supplements can affect the absorption of certain drugs:
Psyllium has the potential to reduce absorption of digoxin, Coumadin, lithium, and carbamazepine. Guar gum may slow the absorption of digoxin, acetaminophen, and bumetranide and decrease the absorption of metformin, penicillin, and more. Pectin may decrease the absorption of lovastatin".
Now I will admit that Webmd may have it wrong, so I'd like you to provide links to some studies backing up the idea that consuming large amounts of fiber have no deleterious effects.
