Humans are designed to eat mostly fruit. We’re frugivores, just like monkeys and chimps. Fruitarian Humans We are the most biologically advanced species on Earth. Fruit is the most advanced part of a plant. It has to be, since it’s responsibilities relies solely on the progeny of the plant itself.
Fruit, in its strict botanical sense, is the fleshy and ripened ovary of a plant, enclosing the seeds. Have you ever met someone who doesn’t like fruit? We’re told that it’s high in sugar so we should limit our intake, however fruit doesn’t really contain any sugar, at least not our conception of it. We’ve mistakenly equated man-made sugar with God-made sugar.
It’s not the same stuff, not even close. Put a strawberry and a cheeseburger in front of a baby and see which she goes for. Fruit is sweet, and it’s sweet for a reason. This is a clue for humans, so they know to eat it. This first clue would be it’s appealing color, which immediately grabs our attention. The second would be it’s appealing aroma.
All species have instructions in their DNA to tell them what to eat and how to live, and humans are no exception. Andrew Smith of the University of Stirling in Scotland believes that trichromacy provides an important advantage for fruit eating species. Humans have so-called trichromatic, or three-color, vision. So do Old World species such as chimpanzees, gorillas and orangutans. Fruit’, the fruit of the plant. The fruit contains the seed of the plant, it’s only hope for progeny and survival.
Because of this, the fruit is biologically designed to be the most advanced part of the plant, and extremely appealing to frugivorous onlookers who will hopefully spread its seeds far and wide. Frugivory is thought to have evolved as a mutualism to facilitate seed dispersal in plants. In general, an animal benefits by receiving sustenance from the plant by consuming the fruit. Fruit is the easiest food to digest, which should right there, tip us off that we are biologically designed to eat it. Just because we are able to digest other foods, does not make us fit for their consumption. Omnivores are designed to eat everything.
Humans can eat meat, but they are not designed to, which means they are not true carnivores or omnivores. Flesh eaters have very short intestines for the rapid expulsion of decomposing flesh. Vegetarians and Fruitarians, including man, have very long intestines, for the slow digestion of fruit and vegetables. Imagine you’re the only person on Earth, there is no infrastructure, there are no restaurants, only you and the wilderness. What are you going to eat? There are animals running around everywhere, so you could kill one and cook it over a fire. But time is of the essence and you need something to eat now, not later.
