Sweetened iced teas, though lesser known, have sugar content equivalent to that of soft drinks. Most store-bought iced teas are full of added sugars, which will cause the release of insulin and ultimately the storage of fat in the liver. Studies show that frequent drinking of such sweet tea may result in the same negative impact as it does with soda and commercial juices. The “natural” or “healthy” headline on the drinks tends to be quite misleading; thus, frequent consumption of these drinks is a serious threat to liver health.
Therefore, sugary drinks, be it fruit juice, iced tea or energy drinks,all worsen fatty liver disease
Keeping these drinks to an absolute minimum or avoiding them might reduce fat accumulation in the liver, lessen inflammation, and impede progression toward more severe liver conditions. For metabolic balance in general, it is advisable to drink water, unsweetened tea varieties, and plain coffee.
