“The cows ignored all other feeds apart from the zinc, before going back to the other feeds. They had got into a vicious cycle. Their food lacked zinc, so they started eating more mixed feed, which did contain a little zinc, but also calcium. Calcium interferes with zinc absorption, so the more they ate, the less they got. Just like the cows, we may be eating more to compensate for a deficiency in micronutrients.

“My two daughters are the only people in these acknowledgements who have taken no interest whatsoever in this book. They are both avid consumers of UPF and, aside from being unsurprisingly willing participants in many eating trials, their contribution has been exclusively negative.”

“Almost every other animal finds sour tastes aversive – experiments done in other primates show that they spit it out.8 But for humans the taste may be useful. Sourness is, after all, a sign of fermentation rather than putrefaction. When bacteria ferment food, they produce acids that preserve it. Lactobacilli in milk digest the lactose into lactic acid making yoghurt, which keeps up to ten times longer.“

“In fact, taste receptors are found throughout the body in the larynx, the testes and in the gut.”
T-testes?

“It may be that the same molecules may be perceived differently when sniffed compared with when they travel from the mouth to the nose. Barry explained: ‘A stinky cheese can smell disgusting – orthonsal olfaction – and pretty much like socks. But it can have a delicious flavour when those odours come from the mouth to the nose – retronasal olfaction.”
Fascinating.

“There’s a lot of literature showing humans’ sense of smell is similar to or more sensitive than dogs, mice or rabbits for odorants in fruit. Mice are good at detecting the molecules found in the urine of mouse predators (although we aren’t bad), and we are better than mice at detecting the smell of human blood”

“the olfactory nerves – the smell nerves – poke through the bone into the soft mucus-covered skin to touch inhaled air. The olfactory system is the only example of the brain sending its own neurons out like a probe. These nerves are covered in hundreds of different receptors – proteins with little pockets on them.”.

“flavours out of context may be messing up the body’s ability to make the correct associations between a nutrient and a food”:
you’re deficient in vit-A so you crave Vit-A rich foods. If (and I’ve not seen enough proof here to say that it is) the flavorings that are based off Vit-A are put into UPF, this vit-A “tag” (flavor) tricks you into eating more while not delivering the deficient nutrient.

“These sort of complex mineral and vitamin interactions are seen in nutritional supplements too, which may be why supplements are generally linked to health problems, including early death. If you take large quantities of calcium, you won't be able to absorb iron. If you take large quantities of iron, you won't be able to absorb zinc. If you take vitamin C, you'll reduce your copper level.”

“According to Ponzter’s data, we burn around 2,500 calories per day at desk jobs, same number of calories as if we were walking a long distance. Since we’re not spending that energy on walking, we spend it elsewhere, on things like being stressed. The hypothesis says that office workers will likely have increased levels of adrenaline, cortisol and white blood cells, all of which make us anxious and inflamed.

“These findings challenge everything about our understanding of how the body uses calories. It seems that people burn the same amount of energy each day whether they walk ten miles or sit at a desk.”
“But it turns out that, if we are active, our bodies compensate by using less energy on other things, so that our overall energy expenditure stays the same.”
