Sugar-sweetened beverages and risk of metabolic syndrome and type 2 diabetes — a meta-analysis
In plain English
The first quantitative synthesis of the link between sugary drinks and metabolic disease, pooling 11 prospective studies and more than 300,000 adults. People drinking one to two sugar-sweetened beverages a day had a 26% higher risk of developing type 2 diabetes and a 20% higher risk of metabolic syndrome than those drinking less than one a month. The effect was larger than the added calories alone would predict, implicating rapid blood-sugar spikes and liver fat.
Why it matters
One to two sugary drinks a day raised type 2 diabetes risk 26%.

Caveats
Observational; heavy soda drinkers tend to differ in weight, activity and overall diet. Some included studies adjusted for body weight — which may lie on the causal pathway — making the 'independent' sugar effect hard to isolate cleanly.
