It may be possible to feed on fruits; while cells there are still alive, they are about to die soon without any prospects of future surviving. If you really do not want to harm the plant in any way, take the seed from the fruit and plant it somewhere. Fruits are for seed propagation only and the plant should really not have any pretensions to you afterwards. ...

No. It is possible but extraordinarily impractical to nourish yourself without killing animals, plants or even bacteria, as many have explained in detail. However, your immune system constantly kills pathogens that infect your body. What's worse, the macrophages literally catch and eat these bacteria alive, so you are very much "consuming" them. You could ...

Well, technically if you are eating something from a plant or animal without killing that plant or animal, then technically you would not be "consuming life" as nothing as been killed. Fruits, for example, can be removed from the tree without harming it and in fact are meant to be removed as that is how the tree reproduces. Ditto with berries, melons, ...

Even on a purely synthetic diet, your body would still use living cells as an energy source. Our bodies contain more bacterial cells than human, mostly contained in our gut. These microbes process any nutrients we ingest and when they die, we absorb their cellular components as nutrition. The lining of the gut is the most rapidly dividing population of ...

Your question is phrased somewhat ambiguously as to whether you're asking about the theoretical possibility, the feasibility, or the practical ability in everyday life. 1) Theoretically, yes. It is chemically possible to produce all substances that humans need to survive without the use of living organisms in the process. In the end, biological systems use ...

Question: Is it possible for humans to live healthy long lives without eating any type of life, i.e no animals, no plants? First, according to a definition of a living organism(biology-online), milk is not live, because it does not have an ability to reproduce itself, among other... My claim: If you consider milk and honey non-live (no DNA), then, yes, ...

It is entirely possible to live without consuming life using only current technology. In fact, there is a company called Soylent which has developed a food substituent designed to replace all eating, entirely. The philosophy of that company is that – food is just a collection of chemicals for the body to process, and that as long as the body gets all ...

The answer to your question is yes it is certainly possible. At one time it was thought that there was something special about "organic" chemicals which meant that they could not be artificially synthesised out of fundamental elements. In 1828 Frederick Wöhler synthesised urea (CO(NH2)2) which is often taken as the first demonstration that the organic v ...

Depends on how you define "life"? Is unfertilized chicken eggs alive? What about cow milk? Well there are bacteria in it. What if you get rid of that bacteria? Then some people would not be able to utilize lactose... Also as Bez mentioned rice grains are quiescent, meaning they are in a dormant state and not really "alive" but again depends on how you ...

It may be feasible to live without consuming anything that was alive, but it would be incredible difficult. For example, all humans need to consume glucose to survive. Glucose is the only food source used by cells in the brain. Plants are the easiest source of food source for glucose. If we can't get glucose from plants, then we would need to synthesize it ...

Living organisms can be divided into hetrotrophs and autotrophs. Autotrophs like plants and algae are able to produce complex organic compounds from relatively simple inorganic components. They are satisfied with sunlight, water and other abiotic stuff and do not need to consume "life". We -- along with all other animals -- are not autotrophs, but ...

The main minerals in tap water are calcium and magnesium, which determine the hardness of water. The main minerals in mineral waters are calcium, magnesium, sodium, chloride, carbonate and sulfate. Tap water from different regions and various brands of mineral water can contain very different amounts of minerals, so it is impossible to make a general ...

Cattles actually hate shrubs which are very tough to break and tasteless(for a cow). Some plants they won't touch are: Lantana urticoides (West Indian shrub verbena), Malvaviscus arboreus var.drummondii (wax mallow) Rhus copallinum (winged sumac) Viburnum acerifolium (mapleleaf viburnum). Morella cerifera (wax myrtle) Ilex vomitoria (yaupon). Source: ...
