High Salt Intake Independent Risk Factor for Obesity?

"High salt intake is the major cause of raised blood pressure and accordingly leads to cardiovascular diseases. Recently, it has been shown that high salt intake is associated with an increased risk of obesity through sugar-sweetened beverage consumption. Increasing evidence also suggests a direct link. Our study aimed to determine whether there was a direct association between salt intake and obesity independent of energy intake. We analyzed the data from the rolling cross-sectional study–the UK National Diet and Nutrition Survey 2008/2009 to 2011/2012. We included 458 children (52% boys; age, 10±4 years) and 785 adults (47% men; age, 49±17 years) who had complete 24-hour urine collections. Energy intake was calculated from 4-day diary and misreporting was assessed by Goldberg method. The results showed that salt intake as measured by 24-hour urinary sodium was higher in overweight and obese individuals. A 1-g/d increase in salt intake was associated with an increase in the risk of obesity by 28% (odds ratio, 1.28; 95% confidence interval, 1.12–1.45; P=0.0002) in children and 26% (odds ratio, 1.26; 95% confidence interval, 1.16–1.37; P<0.0001) in adults, after adjusting for age, sex, ethnic group, household income, physical activity, energy intake, and diet misreporting, and in adults with additional adjustment for education, smoking, and alcohol consumption. Higher salt intake was also significantly related to higher body fat mass in both children (P=0.001) and adults (P=0.001) after adjusting for age, sex, ethnic group, and energy intake. These results suggest that salt intake is a potential risk factor for obesity independent of energy intake."

It's the salt, nothing to do with the "sugar-sweetened beverage consumption" don't make me laugh.

Hat tip to Zoe Harcombe  for finding that piece of nonsense.

There is a direct relationship. Salt is added to drive thirst and additional sugar is added to cover the taste of the salt. When sat is added, the subject will drink more, and thereby consume more, driving up profits. Those that consume more salt will piss more salt. This study proves the obvious, I think.

I agree with you 100% Fred, the viscous circle, all part of the big con. The more you drink, the more you want to drink.

So many who drink these drinks are not aware that salt is added.

The shame of it is does anyone need this type of drink.
Whatever happened to good old water, and not necessarily the bottled type.

Obesity is on the rise due to the huge increase in recent decades of people eating too much highly processed foods, too much hidden sugar, and the drink industry play their part in this.

Something else that came true, Fred Pohl (and Cyril Kornbluth?) back in the fifties or so had a future society where the population was fed a salty snack which made them thirsty for a drink which made them crave a cigarette which made them hungry . . .
