We need 100 g fiber a day
Finns eat less than 15 grams of fiber a day.
The hunter-gatherer of Stone Age whose intestine system we still have ate more than 100 grams. We should do the same to keep our intestine and therefore the entire body firmly healthy and resilient. Bacteria also make the immune cells that kill pathogens.
Because we are indoors animals whose physically light work happens indoors, our consumption of energy is less than half of that of the Stone Age humans. Our consumption is small and the amount of food we need is thus also small – getting a sufficient amount of fiber is not possible without choosing specifically fiber-rich foods, and fiber supplements in addition.
E.g. using leeks instead of onions, adding lentils to soups and stews, soaking seeds and grinding them in a blender with fruits and berries are good fiber supplements. Dried berry powders and psyllium seed husk are also excellent.
Ready-made brans are not recommended, since they are often more or less adversely rancid and always form a lot of acid, thus damaging the body pH.
It’s advisable to grind berries in a powerful blender, because only then will the fiber of the seeds and important nutrients become available.
A varied range of fiber in our diet helps to support a wide range of useful bacteria.
Everybody should learn the fiber content of nutrients for their diet and nutritional awareness.
Almost non-fibrous and low nutritional value carbohydrates, such as wheat and sugar, area of course absurd in a healthy diet.
A generous amount of fiber in the intestines helps the bacteria to form e.g. a lot of serotonin, the neurotransmitter of the 200-500 million nerve cells. The excess goes to the brain making us feel mentally better.
