Children are manifesting increased rates of adult diseases like hypertension or high triglycerides. And they are getting diseases that used to be unheard of in children, like Type 2 diabetes and fatty liver disease.
So why is this happening?
Everyone assumes this is the result of the obesity epidemic – too many calories in, too few out. Children and adults are getting fat, so they’re getting sick. And it is generally assumed that no one specific food causes it, because “a calorie is a calorie”.
I’ve been studying the role that sugar plays in contributing to chronic disease for years, and my research group at the University of California, San Francisco has just published research in the journal Obesity that challenges this assumption. If calories come from sugar, they just aren’t the same.

Diabetes is increasing faster than obesity.
It’s clear that the cause of rising rates of health conditions like Type 2 diabetes isn’t as simple as people just eating too many calories.
Obesity is increasing globally at one per cent per year, while diabetes is increasing globally at four per cent per year. If diabetes were just a subset of obesity, how can you explain its more rapid increase?
And certain countries are obese without being diabetic (such as Iceland, Mongolia and Micronesia), while other countries are diabetic without being obese (India, Pakistan and China, for instance). Twelve per cent of people in China have diabetes, but the obesity rate is much lower. The US is the fattest nation on Earth and our diabetes prevalence is 9.3 per cent.
