Diabetes but some how insulin resistance may happen ,although this is not linked so far with type 1 diabetes.. Consumptions of very & all time outside junk including sugary ,spicy,salty may prone to diabetes. It may cause more complications like cavities, tooth decay, Here is studies for you : - "One study that followed 51,603 women between 1991 and 1999 found an increased risk of diabetes among those who consumed more sugar-sweetened beverages - that's soda, sweetened ice tea, energy drinks, etc. And a massive review of previous research involving 310,819 participants supported this result, concluding that drinking lots of soda was associated not just with weight gain but with the development of type 2 diabetes." but this is not exactly sweets what your husband like the most.
