I just mean a good drink to help go low(er) sugar?
kombucha (low sugar)
coconut milk (no added sugar/low sugar)
It’s a bit of pop science to say that nutrisweet and other artificial sweeteners produce the same insulin response as sugar, but that’s not what the data indicates.
The response is consistently lower.
So my recommendation is to switch to diet soda, assuming the sugary drinks you’re drinking are sodas.
If they’re fruit juices, I would recommend relaxing them with smoothies. The fiber in a smoothie slows the absorption of the sugar, resulting in less of a blood glucose spike.
