*Kinetic energy

There are limits to the temperatures that the human body can endure for long periods. Humans make their own heat but unless it is caught in someway by appropriate shelter or clothing, they’ll need ambient temperatures in a suitable range.

*Water in diet

You don’t need to drink water to live, and you can generate some of the water you need from the fats, proteins, and carbohydrates in your diet, but you will need to have some H2O in your food or beverages to survive.

*Radiation

You can live without sunlight (UV) if you receive enough Vitamin D in your diet. This could be considered a conditional necessity.
There is some evidence that a certain level of high energy radiation is required for optimal health but this remains controversial. You’ll live without it.

*Essential fatty acids in diet

There are only two, for humans: omega-3 and omega-6.
Some others are considered beneficial, or may play a crucial role in specific circumstances.

*Essential amino acids in diet

There are nine of these, for humans: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine.
Some others are considered beneficial, or may play a crucial role in specific circumstances.

*Insoluble fibre in diet

A lack of insoluble fibre leads to increase chance of illness and death for various reasons.

*Dietary energy

Humans need a certain amount of dietary energy intake to cover their metabolic needs and activity. This could come from fats, proteins or carbohydrates, or to a lesser extent from some compounds that don’t fall in any of those categories.

*Vitamins in diet

There are 12 compounds that fit the strict definition of vitamin for humans: vitamins A, C, E, K, B1, B2, B3, B5, B6, B7, B9, B12.

Vitamin D is often included in lists of vitamins, but a well-sunned human will produce enough D to survive. It is a conditional necessity.

*Elements in diet

Humans need H, N, C, O for many specialised reasons but If your diet contains enough water to cover your basic hydration then it will cover any other needs for H and O, if it contains enough C-compounds to cover your energy needs then it will cover your other needs for C, and if it contains enough amino acids, then it will cover your other needs for N and S. So CNOHS is not normally included in this list…

This list contains K, Na, Ca, Mg, F, Cl, Br, I, S, Se, P, Mn, Fe, Co, Ni, Cu, Zn, Mo.
It may contain others including As, B, V.
It should be noted that particularly for the transition metals, humans may require the metal ions to be chelated in specific ways in order to be able to digest them. Eating a spoon of iron filings will not be an efficient way of introducing iron into your body.

it’s the one thing

• Sufficient nutrients to survive (eg. clean: water, air, food)

• Sufficient shelter to survive (eg. clothes, cave, hut)

• Sufficient companionship to survive (eg. friend, lover)

Composition
http://en.wikipedia.org/wiki/Composition_of_the_human_body

Main article: Composition of the human body
The main elements that compose the human body are shown from most abundant to least abundant.

The average adult body contains between 5 and 5½ litres of blood and approximately 10 litres of interstitial fluid.

The composition of the human body can be referred to in terms of its water content, elements content, tissue types or material types. The adult human body contains approximately 60% water, and so makes up a significant proportion of the body, both in terms of weight and volume. Water content can vary from a high 75% in a newborn infant to a lower 45% in an obese person. (These figures are necessarily statistical averages).

The vast majority of cells in the human body are not human at all; rather they are of bacteria, archaea, and methanogens such as Methanobrevibacter smithii. The largest proportion of these form the gut flora. The whole population of microbiota include microorganisms of the skin and other body parts and this altogether is termed as the human microbiome.

The proportions of the elements of the body can be referred to in terms of the main elements, minor ones and trace elements. Material type may also be referred to as including water, protein, connective tissue, fats, carbohydrates and bone.

Although the composition is interesting, note that the body contains scores of elements that are definitely not required, including gold, caesium, bismuth and lead.

yes, some elements are not required

yes, some elements are not required

Only 23 are required, with question marks around another half dozen, and some of the unneeded ones are more common than the needed ones.

e.g. The rarest element by human body composition that IS required by humans is cobalt, which makes up about 20 parts per billion. The commonest that is probably NOT required is rubidium, about five parts per million.

So they pretend their diet of salt pork and rum is actually hen & sherry.

Not bad luck to mention it twice, though.

“Atlantic seamen in the West Indies had a bizarre superstition related to swine. Pigs themselves were held at great respect because they possessed cloven hooves just like the devil and the pig was the signature animal for the Great Earth Goddess who controlled the winds. As a result, these fishermen never spoke the word “pig” out loud, instead referring to the animal by such safe nicknames as Curly-Tail and Turf-Rooter. It was believed that mentioning the word “pig” would result in strong winds. Actually killing a pig on board the ship would result in a full scale storm.”

So obviously there are beverages that don’t contain h20.

Well I suppose at a pinch honey could be considered a beverage.

He hasn’t peeped in for a few weeks. I was hoping he’d see the thread about enhancing human memory, since he was suffering from a lot of short term memory problems. Might have cheered him up.

I suppose you could have a sip of vegetable oil but I wouldn’t recommend it.

In any case, what I said did NOT imply the existence of anhydrous beverages.

Re: Vit D.

Do places such as Norway have fortified foods containing vit D? Australia does and we’re the sunny country, so I would assume that having six months of darkness would also necessitate vit D added to foods.

morning, back to a much more pleasant temp of 11 degrees with a top of 23. Norway has fortified milk and bread, but it’s not mandatory so you’d have to specifically select those foods for vit d.

A quick Google suggests non-Western people in Norway are more at risk of rickets, especially the Pakistani population.
