"What goes in, must ALWAYS come out" - It just may come with unexpected troubles

Author's Claims

1) Roach believes that tasting, has nothing to do with actually tasting.

"Eighty to ninety percent of sensory experience of eating is Olfaction", or in other words, comes from the ability to smell.

2) She claims that by chewing your food more, you are able to absorb more nutrients.

"By delivering heaps of poorly chewed food, to the intestine, we overtax the gut and pollute cells with the by-product of 'Putrid bacterial decomposition'".

3) Changing people's bacteria is a more effective way for treatment of disease than changing their diet.

"bacterial demographics are likely to influence their day to day behavior"

"Depending on what is living in your gut, you may or may not benefit from what you eat."

Relevant to Our Lives

1) The concept that not all of our taste receptors are useful is relevant to us, because, "only the tongue's receptors report to the brain."

2) The concept that digestion is chemical is relevant because for the human body, "protein is easier to digest than vegetables." This is because the cellulose fiber in the vegetables are what make them harder to digest. Humans lack the enzyme necessary to digest it.
