If not, Anjana says companies will seize on uncertainty and inconsistency in the scientific evidence to preserve the status quo. "Quantifying lifestyle factors is not always straightforward. Take the fizzy drinks survey. It did find a correlation between estimated added sugar intake and cardiovascular disease. But the groups being compared were at opposite extremes of the consumption spectrum: either heavy or light consumers. As pointed out by David Spiegelhalter, Winton Professor of the Public Understanding of Risk at Cambridge University, “the increased hazard for moderately different groups is not that great”. Cutting down on added sugar would have substantial benefits for overall public health – but the average person might not benefit that much."
