A report in the US linking soft drinks with obesity has been criticised for missing "the commonsense point."

The Center for Consumer Freedom yesterday (10 August) queried the findings of a report published earlier this week in the American Journal of Clinical Nutrition. The report, conducted by the Harvard School of Public Health, warned that an extra can of non-diet CSD a day can cause 15 pounds of weight gain a year.

The Center pointed out that the review "entirely misses the point that 150 extra calories of anything will cause people to gain weight".

"It doesn't take a Harvard Ph.D., let alone a high school diploma to realise that the more calories we eat, the more weight we'll gain," said senior research analyst J. Justin Wilson. "It's a basic law of nutrition. Whether it's an extra bowl of lima beans, shredded wheat or can of soda, eating more calories than you burn will always lead to weight gain."

"This report completely ignores the other side of the obesity equation: energy expenditure," Wilson continued. "From moving sidewalks in airports to electric staplers, Americans have engineered exercise out of their lives. This study does a disservice by providing a feel-good distraction that places the blame on a single food, but does little to address the fundamental changes in how we live."

Earlier this year, the Center released a report which distanced CSDs from obesity. The report suggested that inactivity is more to blame for weight gain that soft drinks.
