RE: [100% veg*n ] Live food debate

[Guest guest]

Specific heat of water 4186 J/KG/C.

Assumptions water from 10 degrees C to 50 degrees C (Change of 40 C)

Energy required to heat 0.5 litre of water (approx 0.5 kilo).

 

4186*40*.5 = 83 KJ

 

Not much in the scheme of things. Especially considering the body wastes

that amount of heat anyhow.

 

IMO food benefits from light cooking, and not over cooking. Perhaps the raw

foodist here overcook their food?

Ok John, here's what I am thinking.

 

You can't realistically compare the energy used to heat food by a

kettle or stove, with the energy needed to do the same work with in a

human body. The human body is designed to consume food (although

which kind of food is another issue), and is there for much more

efficient at doing this.

 

I can speak also 'unscientifically' from personal experience that

when I do consume live food I have more energy to carry out my normal

activities (my days are usually rather active, I have a little

toddler to keep me on my toes, and we cycle daily, since we don't own

a car). If I eat cooked food I feel more sluggish and tired. I think

its more of an enzyme issue, otherwize I'd be exhausted when I ate

raw food spending all my energy raising it to body temperature

(instead of feeling full of energy, like I do). If the enzymes in

cooked food are destroyed, then surely the body has to work harder

for the body to digest it. In live food the enzymes are ready and

waiting to assist the body with digestion.

 

I am not sure about this energy to heat food in your body issue, and

can only speak from my experience.

 

We are the only animal on the planet that cook food. That tells a

story in itself don't you think? Food for thought!

I couldn't agree more, especially since the whole organic farming

thing is supposed to be about 'the whole cycle'. The amount of energy

consumed in bringing food to our plate must be astronomical!
