How did cheap and dirty become delicious?
(This post owes a huge debt to “It Starts With Food” by Dallas and Melissa Hartwig – buy it for yourself, and for everyone else that you care about…)
Millions of years before food scientists existed, our ancestors developed ways of helping them distinguish, and then remember, between good sources of nutrition, and bad. Sources of quick energy tasted sweet; sources of dense calories tasted fatty; and salty tastes were a sign of foods to help hydration, or maintaining hydration.
The net result: we are ‘hard-wired’ to seek out sweet, fatty and salty foods. It’s worth mentioning that the fruit our early ancestors ate was probably a fraction as sweet as the fruit we enjoy – we’ve had hundreds of thousands of years to select the sweeter mutations and make them dominant in their species. Fat sources would have been unprocessed, and salt simply found in more sodium-rich foods.
Everything our ancestors needed to nourish themselves was available in nature.
We all know that food can elicit an emotional response, and if our brain is receiving the signals that we’re being nourished it will release dopamine and endorphins. Thus, our ancestors would not only be nourished, but would feel good too.
Fast-forward to around ten thousand years ago, and our less-distant ancestors developed agriculture – allowing for production of food by a few for many to consume, and the potential to store food for long periods (never mind, for now, that this food was less nutritionally dense than more traditional hunted/gathered food).
I only mention agriculture because it allowed for all sorts of development, not least the study of sciences. Not needing to hunt or gather, some of those ancestors of ours had the time to indulge in more lofty pursuits. So, in more than one sense, agriculture gave us food scientists.
Fast-forward again, this time to the middle of the twentieth century, and manufacturers of food products had the knowledge and facility to exploit our hard-wiring to generate masses of profit. All that was necessary was to make food products that were sweet, fatty, or salty, or (ideally) a combination – doughnuts, potato crisps…..
These food products tasted amazing, and ticked the boxes that our DNA was programmed to recognise as nutritious input.
Here’s the best part, and the answer to the opening question. Real food (animals, fish, vegetables, fruit) can be costly to come by, might require a lot of looking after, careful handling and so forth. Those crops that lend themselves to an industrial scale of production (grains, corn, rape, soy, sugar beet etc) do so because they’re much less complicated they can be mechanically harvested and require minimal care in their handling en route to processing. Therefore they’re relatively cheap, and never mind that they’re a poor source of nutrition, the food scientists have an array of additives, or means of manipulating them so that they can be turned into ‘super-normal’ (super = beyond) tasting sweet, salty or fatty foods – way beyond what nature could conceive.
What effect does that have on our emotional response to food, mentioned above? Natural/real food, with its modest level of sweetness, fattiness, or saltiness, rapidly loses the ability to get our brains excited enough to release those feel good chemicals. How could it compete with ‘super’ ‘Frankenfoods’?
Have a look at the ingredients of, say, a packet (tube?) of Kellog’s sour cream and onion Pringles:
Dehydrated potatoes, vegetable oil, vegetable fat, rice flour, wheat starch, sour cream & onion flavour(hardened vegetable fat, onion powder, sour cream powder, dextrose, flavourings, sugar, sweet whey powder, lactose, milk protein, potato starch, food acids:citric acid, lactic acid and malic acid), emulsifier:E471, maltodextrin, salt, modified rice starch
Might any of those ingredients look like food? Sugar and salt, probably; dehydrated potatoes, maybe; modified rice starch….?
Where does this stuff come from…..
“Disc centrifuge for vegetable oil refining are widely used in continuous degumming, neutralizing, dewaxing, and washing of vegetable oils, such as peanut oils, colza oil,palm oil,oliver oil,sunflower oil,cottonseed oil,corn oil etc.”
Makes for an interesting contrast with ‘first cold pressing’, no?

Mmmmm, ‘spray process’.
(It was an eye-opener having a brief search for suitable pictures, especially if one is viewing them from the ‘food’ & ‘industrial’ are two words that don’t go together perspective)
Perhaps this was my subconscious at work – I thought of Pringles as an example before I remembered their advertising strap line: “once you pop, you can’t stop”. They make a virtue of the fact that their food product is addictive…. Plus, it’s cheap to produce, dirty (in that, if shown them all individually, you probably couldn’t identify any of the ingredients, apart from sugar and salt), and (doubtless, to many) delicious.
Why would you want to eat real food ever again?
