We do have way more cancers, a big reason we know about is our food choices. We don't even know the impact of hard things to measure yet, like the impact of all these things on our gut biology. It's not a new discovery that eating a lot of sugary foods leads to greatly increased diabetes, and now we are learning more about how artificial sugars have their own impact. So basically, it's increasingly obvious that artificial sugar drinks are not good for you too, maybe in different ways than "natural sugars".
