Pseudoscience is essentially opinion, not any form of science. Statements like "eat more fiber" have the hallmark of pseudoscience since it is made with ignorance of how much fiber I am currently eating. There is a optimum amount of any ingredient in any one persons diet. Without knowing how much, it is only opinion.
