The Reference Daily Intake (RDI), food nutrients


Thanks for all your work and all the inspiration!
I’m on my sixth week of only fruits. It’s fantastic! A few questions have come up..
The RDI – is it valid? To what degree?
Iron seems to be tricky to get from fruits, is this where seeds come in, pumpkin seeds? Parsley, eventhough it’s a herb?
When I talk to other people about species specific food and humans being frugivores I have come across arguments like chimpanzees, which I presume also are frugivores, have been known to hunt, kill and eat other smaller monkeys – any thoughts on that? Are these chimpanzees just as confused as we are?


Terrain answer:

RDI takes approximate levels found in the population and then rounds up for a “level of safety”. For as much as science knows about our nutrient needs, we are finding new nutrients constantly and the more we appear to know on this subject the more something new is discovered.
In reality, deficiencies are extremely rare and it is far more likely that the issues is an issue of imbalance, or excess of one nutrient created by ingestion of unnatural substances which depletes another nutrient.
What we do needs is whole foods in their whole form which are suited to our physiology.
Iron is found in sesame seeds, figs, peaches, green leafy vegetables, apricots, lettuces, raisins, Walnuts, Almonds, Berries, Dates, Cherries, broccoli in larger quantities and trace amounts of iron are found in nearly every fruit.
If we are not damaging our digestive tracts ability to absorb and assimilate then we would not be “deficient” in any nutrients following our natural diet. However, eating cooked foods, spices and salt all create scar tissue, mucoid plaques and other issues which can lead to poor absorption of nutrients. Eliminating those harmful substances from our diet leads to better absorption and a rapid correction of most perceived deficiencies.
Nuts and seeds are suitable foods, herbs are less suitable as they contain irritating oils which damage the digestive tract.


As for the Chimpanzee issue, these claims appear to be based upon stool samples tested for DNA and many experts feel that the results are inaccurate and that the DNA is present due to reasons other than ingestion, like other animals urinating on the stool samples or sticking their fingers in the stool in search of undigested bits of fruit. I have yet to see any claims that are backed with actual evidence of the consumption/ingestion. They might exist in rare cases, but there is as far as I am aware, an absence of reliable evidence.
