Burning foods

Postby nanoscaled » Thu Feb 08, 2007 2:31 am

In biology class today, we were burning three types of foods to see how much energy (Cal) were given off.

Marshmellows, potato chips, and Pork grinds.

Which one would have the most calories and why? and also just another curious question, if I had gone on a strenuous hike, which one among the three would be the best to bring? Thanks.

you'r right. but, i think he/she already know the portion of it is the same.
then.. what is the answer?

>>>
since i do not ever try Marshmellow... i am affraid if i will give a wrong answer.. so i cannot give any comment for that.

i think the better one is pork.. than pottato chips :)
i think you all know about this. hehe..

>>but, if i'm allowed to make just a prediction/quess.. i still choose pork. :? after all.. it is from meat. haha... that's the reason.
by the way.. did you pick the low quality pork or the best one? i'm not sure if it was the low quality...

If the amount of the three types of foods is the same, the pork grinds produce the most energy compared to the another two types. This is because the pork grinds contains saturated fat which only found in animals. The saturated fat has fatty acids that without a single double bond in the hydrocarbon chain. After a strenous activities, I suggests that you can consumes marchmellows because it contains unsaturated fat which can produces energy and do not affects our health.

I think the point of the question was that you should consume the item with the most calories, namely pork grinds.

Yes, sorry about that. It is pork rinds. Anyway, thanks for all the help you guys. The actual results were up and pork rinds won over the potato chips. But don't the potato chips also contain saturated fat?

Keep in mind that the calories you're measuring are -

- not food Calories, which are 1000 times bigger.

- not a way to measure food calories, since some indigestible materials (like cellulose in your chips) will still burn. That won't matter much in these particular foods, though.

or something like that, read the potato chip packet.

actually it's 9.1 cal/g and 4.3 cal/g...
And it doesn't matter if you use food calories or energy calories, the ratios will be the same...
