Fibers and intestinal health
The Stone Age man ate fiber approx. 10 times more than we usually eat. Now the recommendation is 50 g fiber / 1000 kcal.
That amount of fiber equals 700 g - 1100 g feces per day, and the speed of the intestinal flow is less than 30 hours. Fiber means a lot to eat for the good bacteria (it’s their only food), which enables them to produce protective cells for the immunity system, and some vitamins. It is good if the sources of fiber are different, because thus the spectrum of bacterial species is greater and their protective effects are better.
A speedy flow guarantees that there is no time for the old intestinal contents to produce harmful chemicals. Thus the bowel wall (Epiderm) and the intestinal villus and follicles remain healthy and absorb nutrients well.
A leaking bowel is chemically and mechanically consumed by the bacteria and intestinal content, and it is of course inflamed, and leaks harmful substances into the abdominal cavity. The inflammation of intestinal nerve cells has a direct connection to brain health.
Inflammatory bowel syndrome (IBS) is a result of poor intestinal health, where the lack of the correct fiber and subsequent inflammation can also easily cause cancer. Crohn's disease is a corresponding disease in the small intestine.
A good intestinal health is obviously a powerful brain health and mood enhancer that prevents memory diseases.
All these are purely lifestyle diseases. All are also completely curable by the right diet even if the pharmaceutical industry is trying to make us believe otherwise. There is a lot of evidence.
A patient that is cured from IBS is a bad customer for drug industry.
The best sources of fiber are seeds, nuts, berries, vegetables, beans and lentils in particular, and raw cocoa. Fruits are the weakest source. Oats are good and also the whole grain fiber, if it otherwise is suitable – that is an obstacle for many. Bran are not good because they acidify the body.
Grain gluten, respectively, impairs intestinal health, as do also additives and anti-inflammatory drugs.
