This is Why Brits Have a Coffee Addiction – And It’s Not the Caffeine
As autumn settles in and the mornings turn crisp, the UK’s coffee chains will be launching their Autumn specials nationwide. With the UK consuming approximately 98 million cups of coffee daily, it’s clear that coffee isn’t just a morning ritual – it’s a national obsession. The average person in the UK drinks about two cups of coffee a day, but according to a food expert, it’s not the caffeine keeping them hooked – it’s actually sugar.
Jonathan Sitson, founder of QuickWhip Whipped Cream Chargers, explains that sweetened iced coffee triggers the brain’s reward system, creating a “pleasure hit” that keeps people reaching for more.
“It’s not just caffeine that gets you hooked,” Sitson says. “Sweetened iced coffee triggers dopamine in the brain — that pleasure hit is what keeps people coming back. If you’re trying to cut back, start slow: swap one sugary iced coffee for a black one each week.”
The problem? We gulp iced coffee down in seconds. That cold, sugary rush hits faster than a hot brew, intensifying cravings. Many popular drinks from Costa, Starbucks, or Pret can contain the equivalent of several chocolate bars’ worth of sugar — often disguised by syrups and flavours.
Why coffee shop drinks are iso addictive:
- Blended Cold drinks are consumed quickly, delivering sugar and caffeine fast.
- Sugar sparks dependency similar to other addictive substances.
- Caffeine gives temporary alertness followed by an energy dip, prompting another drink.
- Marketing has normalised iced coffee as a “daily treat” rather than an occasional indulgence.
Worst UK High Street Coffees for Sugar Content:
- Starbucks Pumpkin Spice Frappuccino – 48.4g Sugar
- Starbucks Pumpkin Spice Latte – 32.g Sugar
- Costa Coffee -CHOCOLATE FUDGE FRAPPÉ WITH COFFEE – WHOLE MILK – MEDIUM – 43.3g Sugar
Reddit users admit they know the feeling:
u/514sid: “At some point it becomes a dessert instead of a cup of coffee… makes sugar consumption very difficult to regulate.”
u/AmNotLost: “Try cutting milk and sugar bit by bit — black coffee grows on you!”
u/justinn: “That one small cup of iced coffee with those extra sugar packs and cream will have more calories than your average soda.”
Research backs it up. A 2021 CDC study found daily consumption of sugar-sweetened drinks was linked to poorer mental health — a pattern not seen with natural fruit juices, highlighting the unique impact of added sugar.
For those trying to cut back, Sitson advises gradual change:
“Black coffee or coffee with minimal sweetener is much better. Reduce sugar slowly rather than quitting cold turkey — it’s more sustainable and less of a shock to your system.”
As Autumn sets in, it might be the perfect moment to swap that iced coffee for a warmer, spiced alternative — still indulgent, but easier on your sugar intake.
