A wife has told of her frustration as her health-obsessed husband refuses to eat any processed food, including supermarket ready meals.
Dinah van Tulleken ordered husband Chris to "make the bloody dinner yourself" when he snubbed the pre-prepared lasagne she had bought from Aldi.
But Dr Chris van Tulleken, an infectious diseases doctor who's become known for his healthy eating campaigning, told his partner he'd rather go without than eat something he wouldn't call food - and said their young daughters shouldn't have it either.
But while Dinah is proud of Chris' work in tackling the nation's growing obesity crisis, she admitted it has taken her "a while to be won over".
"I'm married to the man who will apparently 'change the way we think about what we eat forever,'" Dinah said.
But Chris, 44, whose book Ultra-Processed People was released last month, found a large proportion of Britain's food is not only fatty, sugary and salty, but is also industrially processed.
It's meant he has changed his diet and Dinah has found it tough to feed their family.
She continued: "I'm incredibly proud of what he has achieved and delighted he's trying to improve the nation's health. But I will confess it has taken me a while to be won over.
"It's also fair to say that living with someone fired with the zeal of a new convert has its own challenges.
"First, I was OK with not changing the way I thought about food. With a full-time job as this newspaper's fashion editor and two small children — Lyra, five; and Sasha, two — I had enough going on my life."
Writing for the Daily Mail, the mother explained she often would look for ways to make "life easier" after a busy day at work and these approaches often happened at mealtimes.
But now Chris, born and raised in London with his identical twin, also a doctor, finds ultra-processed food (UPF) "repulsive" and "won't touch it".
He's even ditched Alpen, dodged a particular brand of peanut butter, and chucked Eat Natural snack bars.
The doctor found Pret's Mature Cheddar & Pret Pickle sandwich contains an emulsifier used in McDonald's Big Mac buns, Mail reports.
The couple have also changed their daughters' diets following Chris' research.
Dinah added: "I'm spending a large percentage of my monthly wage on freshly baked sourdough from a deli, and Sunday afternoons are reserved for batch cooking.
"To be fair, Chris does most of this, but it's family fun and the girls get stuck in licking bowls and generally making a mess as we whip up vats of bolognese, chilli and chicken curry."
