On the other hand, humans who consider themselves not gullible i.e. health-conscious - have to constantly look out for undesirable elements sneaking into their food in the form of unhealthy fats, sugars and the relatively unknown genetically modified food.
To sort out myths, half-truths and the truth is also a challenge. Many MLM companies do a good job in keeping the old story of autointoxication pretty much alive.
How could I not mention a party called "opposing view" that is, in opposition to mainstream medical concept, even denying the usefulness of dietary fiber in relieving constipation with ultra-sophisticated reasoning?
The saddest irrefutable fact is that constipation is a part of our mortality. The most advanced medical achievement to date is still unable to completely eradicate constipation as a side effect of medications especially for patients who could not help being grievously ill or injured.
On the brighter side, countless inexpensive and even free natural constipation remedies do exist under the sun. Some aspects of traditional wisdom from different cultures I think is worth looking into if we are willing to view their strengths and weaknesses objectively.
