A new paper by lead author Robert Lustig (MD, MSL UCSF Benioff Children’s Hospital San Francisco) and Jean-Marc Schwarz (PhD  College of Osteopathic Medicine at Touro University California) hints at the massive improvements to children’s health with just 10 days of cutting sugar from their diets.

This paper (still in preprint) has been discussed before at a conference in San Diego as well as being released in Feb 2016 in Obesity magazine, yet the findings of it are massive.

EDIT: The preprint edition of the paper is here (PDF). __Lustig, R. H., Mulligan, K., Noworolski, S. M., Tai, V. W., Wen, M. J., Erkin-Cakmak, A., Gugliucci, A. and Schwarz, J.-M. (2015), Isocaloric fructose restriction and metabolic improvement in children with obesity and metabolic syndrome. Obesity. doi: 10.1002/oby.21371. The study was funded directly by the National Institutes of Health.

Reducing consumption of sugar for even 10 days , even without reducing weight or calories, has the power to reverse a series of chronic diseases (including high cholesterol and blood pressure) in children.

This is massive because it does not talk about reducing fat intake or oil or saturated fat (none of which are relevant anyway… as past I have written in the past) . In fact, Robert Lustig mentions “This internally controlled intervention study is a solid indication that sugar contributes to metabolic syndrome, and is the strongest evidence to date that the negative effects of sugar are not because of calories or obesity“.

Caveat: Participants were identified through the Weight Assessment for Teen and Child Health Clinic (WATCH) at UCSF Benioff Children’s Hospital San Francisco, an interdisciplinary obesity clinic dedicated to targeting metabolic dysfunction rather than weight loss. Recruitment was limited to Latino and African-American youth because of their higher risk for certain conditions associated with metabolic syndrome.

This was not a survey, but a controlled trial – 43 children between the ages of 9 and 18 who were obese were given nine days of food with restricted sugar, but were carefully given diets to maintain the same fat/protein/carbohydrate  plus calorie levels as their previously reported diets. Very interestingly – they did add other carbohydrates such as bagels, cereal and pasta ! In fact, just taking out the sugar meant the kids felt more full.

And in just 9 days, every aspect of the kids’ metabolic health improved.

The released paper will have more details on this subject – but the information is clear: cut down on sugar (even those in fruit juices) to improve kids health. Leave those egg yolks and butter alone.
