Another major study has found that childhood obesity worldwide has multiplied 10 times in 40 years.
124 million 5 to 19 year olds were obese in 2016, compared with 11 million in 1975. Another 213 million were overweight in 2016.
Obesity now affects 6% of girls and 8% of boys. Yet there are also 75 million girls and 117 million boys who are underweight.
Adult obesity over the same period has increased from 100 million to 671 million, with a further 1,300 million overweight.
The World Health Organisation analysis attributes the causes of increased obesity to food marketing, higher pricing of healthy food and government polices.
I have long argued that government policies are lacking. I also accept that food innovation and marketing has been effective. But I disagree that healthy food is any more or less affordable than other food.
