Hypothesis + Experiment + Conclusion = Science

1) Hypothesis: You should chew your food thirty times before swallowing.
Experiment:
Split a bottle of sink de-clogger between 4 glasses, and cut a steak into bite sized chunks and split between 4 bags.
i) Empty 1 bag into a glass.
ii) Hit 1 bag with a tenderiser 10 times before emptying it into a glass.
iii) Hit 1 bag with a tenderiser 30 times before emptying it into a glass.
vi) Hit 1 bag with a tenderiser 50 times before emptying it into a glass.
After 4 hours sieve and weigh the remaining solids.
Expected Results:
i) Lots left.
ii) Some left.
iii) Little left.
iv) Not too different from iii)

2) Hypothesis: People can't divine for metal.
Experiment:
Stolen from Dawkins.
Experimenter 1 places a metal object under a small fraction of a number of buckets, records this, and leaves.
Experimenter 2, without meeting Experimenter 1 leads the diviner into the room, and lets them test each bucket with divining sticks, and records the result.
The experimenters results are compared.
Expected results:
The number of buckets whose contents are correctly identified is not significantly higher than would be expected if the selection was at random (this number to be determined before the experiment starts).

Solids in the stomach

Speaking as someone who works on a gastric pathogen in a GI lab... yes and no.

The retention of a particular structure (the afore-deleted sweetcorn being a perfect example) after both mastication and gastric processing doesn't mean that it's not of any further nutritional benefit. Depending on what microflora you have in your lower GI tract, you may be extracting more nutrients as the bacteria take a whack at it, especially through the large intestine.

And re: a more digestive-juice-like mixture, can you purchase powdered meat tenderizer any more? That's usually a mixture of digestive enzymes (papain, calpain, collagenase) purified up from sundry sources (papaya, pineapple, some bacteria, some intestines, and so on).

Hrmm, there's an interesting idea for a public experiment. Take some of the more exotic fruits, juice them fresh, and test them for protease/collagenase abilities.

The "thirty times" bit dates from a time when food was a lot less processed than today, and had a lot less fat in it.
