What is the Natural Human Diet?


Every animal on our planet is anatomically designed to eat a certain narrow set of foods. It is understood that the foods most easily accessible and readily available for any particular organism, are in fact the foods that incur the smallest possible burden on the organism. Take for example the sea otter. While many of them learn to smash rocks against clam shells to break them open, this is a process that costs more energy than it produces. The sea otter’s natural food source then is not clams, but the small fish that occupy the same waters as the otters, and of which they can easily obtain nutrition without over-exerting themselves.

Humans are classified as frugivores. Our natural diet is fruits, tender leafy greens, tender vegetables, nuts, and seeds, with fruits being predominant. Our natural diet is easy to digest and assimilate, which avoids overworking our cells and organs and creating excess waste.

Fruits provide everything that humans and all frugivore species require to survive and thrive. Proteins, in their usable form of amino acids, fats (fatty acids), vitamins (co-enzymes), minerals, various trace chemicals, and most importantly SUGAR and WATER.

The human body runs on carbohydrates (sugars). Sugar is the fuel for every one of our cells, including our brain cells. It is vital to make the distinction between simple sugars (monosaccharides), like fructose on which we can thrive, and complex sugars, such as Disaccharides – sucrose, lactose (milk sugar), maltose, or polysaccharides – starches, dextrin, Glycogen (stored in the liver) or cellulose.

Fruits match our anatomy and physiology. We see vivid colors allowing us to spot colorful fruits in green leaves. Carnivores and omnivores have a limited color range. Human sight is anatomically designed to be attracted to the bright, pleasing colors of ripe fruit.

We have long slender fingers with a delicate sense of touch to reach into trees and bushes and find the delicate fruits and pluck them from the tree.

We have a weak sense of smell because fruits have strong, pungent, pleasing aromas when they are ripe. We do not need to have a strong sense of smell. Conversely, carnivores and omnivores have a strong sense of smell because prey foods do not have strong smells. Humans can only smell rotting carcasses and their smell is repulsive to us.

Humans have a “sweet tooth”. Our taste buds are tuned to allow us to sense when our natural food is ripe and ready to be eaten. Our senses also warn us of poisons. Bitter tells us that the fruit is unripe or the food is toxic. Sour tells us the fruit is overripe and no longer suitable – rotten food is sour. Fruits contain a little bit of salty flavor, but overly salty foods burn and cause discomfort to our senses. Spicy plants burn our tongues. They also make us sweat and our noses run to warn us that they are toxic. But sweet tastes tell us that our natural food is perfectly ripe and ready to provide us with the essential sugars our body needs to run every cell.

Taste buds are not for emotional highs, they are for survival. They are the messages which tell us what is our food and what is poison. They also tell us when our foods are ready to be eaten for peak nutrition.

We crave sugary desserts after heavy meals because our cells are desperately seeking energy. Sugar is energy. When we properly feed our bodies on fruits those intense cravings for ice cream, cakes, and cookies disappear.

We are attracted to the sweet taste of fruits. They appeal to us and delight our senses. The sight and smell of blood and gore, on the other hand, repulses us. We cook animal tissues and coat them in fruit-based sauces (orange chicken, barbeque sauce, etc) to make them palatable to our senses. We cannot stomach the flavors or smells of raw unadulterated animal tissues. We do not salivate at the sight of blood. We do not relish eating the intestines or bones or organs of a warm body. But a carnivore and an omnivore do.

All carnivores and omnivores eat the bones, feet, fur, and feathers of their prey. These are all essential parts of the diet. On a side note, did you know you can kill a dog by feeding them meat without bone? But they can survive and thrive on bones with just tiny meat scraps attached. All meat-eating species require bones to survive on their diet of flesh foods.

Carnivores and omnivores all have sharp fangs and claws to facilitate ripping through the skin and breaking through the skull bones of their prey. Humans have weak nails perfect for scoring the skin of fruit but useless for ripping the flesh off of a chicken or a cow. Humans have weak teeth and incisors for breaking the skin of an apple or a pear and taking chunks out of fruits. Chewing on bones would break and wear down our delicate teeth.

These are just a few of the anatomical features that humans have based upon our natural diet of juicy, water-rich, easy-to-digest, sugar-filled fruits!

    1. Most people would love to see these types of studies but the problem is that is not how studies work. The pharmaceutical industry pays for studies for the benefit of the pharmaceutical industry. They don’t pay for studies that put them out of business. They will only pay for a clinical study if the study can result in a patentable product they can sell. Marketing teams love clinical studies, news media loves clinical studies so they can keep the public confused and buying the drugs their advertisers sell, but generally speaking, people looking for health don’t look to studies except to confirm what we already know. Luckily for us we have actual science that can teach us how our cells work, how disease is created, how it is reversed, we can know the natural human diet, we know the effects of each type of food and how the body breaks them down, assimilates and eliminates, in other words, without a single clinical study funded by the pharma industry we can know everything we need to know through unbiased sources that make no profit off us.

  1. Hi Lauren,
    I truly appreciate your sharing this valuable information!!
    I wanted to print the dog diet so I can read it as I go to prepare for my 3 little dogs, but the pretty pictures and font takes up a lot of ink and paper.

    Can I find a copy of it in just plain typeset ?

    Thank you so much for your help!,
    Debbie, Whisper, Murphy and BabyGirl (my adopted Maltese furbabies)

  2. my dogs are seniors and have no teeth ,they are use to cooked meat and will not eat anything else, not even interested in fruit and veggie forget it they pick it out of the meat, any suggestions for them?, they are so very set in there ways one is a 4 pound yorkerthe other is a 4 pound havernese, for the meat i give then quail and or cornish hens i trim the fat and dont let them have the bones as with no teeth and being its cooked i dont want them to choke, my yorker has hypo thyroid and the havernese is always itchy, i love my babies and want to do the best for them, anything as advice i appreciate

    1. Hi Diane, Dogs must have bone to eat meat. It is essential. It cannot be omitted. You can kill a dog or any omnivore or carnivore quickly by feeding them meat without bone. The bone is the alkaline element that allows the body to manage all the acids from the protein. Without that the body will quickly run out of alkaline minerals to maintain its Ph levels. All of my dogs except 2 are seniors. I only rescue seniors. Many without teeth. If they still have any teeth I always let them eat the bones whole because that is the safest and healthiest option, but if they have no teeth at all or they don’t have enough teeth to break the bones (they need at least 2 molars that line up top and bottom) then I will grind the bones with the meat. The grinder that I recommend is listed on this page – https://www.therawkey.com/recommended-products-and-tools/ under food preparation. I have a video here that shows how to prepare the meat for grinding. The grinding section starts about 8 minutes in – https://youtu.be/NxoulehYZwk

      All dogs will eat fruit. I have had more than 125 foster dogs and not one has refused to eat their natural foods but some have been more stubborn than others. If you join our Facebook group here: https://www.facebook.com/groups/700078481585631/ we have lots of posts discussing how to get the picky eaters to eat their fruit. I will also be putting an article together very soon on how to get a picky eater to eat their fruit so I will link that here as soon as it is published.

  3. Hi,

    nice article as always, thanks a lot Lauren.
    But i spotted a mistake, you mentioned that glucose was a complex sugar in your text along with starches…

    1. Thank you! It looks like there were a few issues in that paragraph, something must have gotten deleted during editing accidentally. I rewrote the whole paragraph, hopefully it is more clear now.

  4. You mention fruit for human.
    Why. What about that diabetic or the person with hyperinsulinemia? The insulin is high…
    Pcos ladies are told stop the Insulin spike also told as we age we need more complete proteins so muscles are wasting .
    Pls help on these manner

    1. Diabetes II is a disease of fat toxicity. Diabetics thrive on a fruit diet for 3 reasons. 1. It is our natural diet and any time the body is already in distress we need to even more so be providing for its natural needs. 2. It is the fat in our body and the fat in our diet which blocks the sugar from entering the cell. High blood sugar is a result of the body not being able to efficiently move the sugar we consume from the blood stream into the cell.

      Sugar is essential to the functions of every single cell in the body. So restricting the intake of fruit sugar is counter to health. It alone will create conditions of disease, so we cannot expect to eliminate an essential requirement of health and return the body to a state of health. Since fruit is low in fat the body that is fed the natural diet rapidly reverses diabetes and other blood sugar issues because the body is able to eliminate the excess fat quickly.

      The sugar itself was never the problem but just the red flag warning you of the fat issue. When we try to restrict sugar the only option is to eat more fat which then causes more fat to clog the cells. But when we put the conditions of health into place then the body can eliminate the underlying cause and health can be restored.

      So in the medical model they are essentially shooting the messenger, stopping the intake of the red flag warning, the sugar, but never addressing the cause, the fat. In the health model we address the cause by eliminating the fat.

      If you or anyone you know suffers from diabetes I highly recommend the book Mastering Diabetes by Robby Barbaro. You can get a copy here – https://amzn.to/4bFIhXd

      Here is a video that explains about blood sugar issues and fat toxicity – https://nutritionfacts.org/video/diabetes-as-a-disease-of-fat-toxicity/

      PCOS is also easy to fix when we return to our natural foods. The body will not retain disease conditions if we provide the conditions of health. The body is always trying to move itself back to a state of pristine health, so as long as we stop inputting the causes of disease the body will automatically correct all disease conditions. Disease conditions require work to maintain and grow them. But health only requires that we stop the input of the causes of disease.
