For any regular consumer, we would assume that all these 3 brands just contain coconut juice water. However, only one of the brands in the photo is 100% coconut juice, The other two contains additional water and cane sugar. So inadvertently the consumer may be taking in additional sugar with those drinks.
I am not saying that the level of sugar is that much or harmful to health, of course. Neither am I saying that any one of them are lying, since they never claim to be only all coconut juice. At the end of the day, consumers needs to be educated by reading the ingredients list to know what they are buying into.
By the way, its the brand of the left of the photo, it only contains coconut juice,
