While there’s nothing to stop you drinking green juice everyday, it can be problematic if you do so to replace a lot of meals.
Green juice is very healthy, but there’s one thing it doesn’t contain which we need to consume every day: fibre.
If you rely on green juices as a complete replacement for fruits and vegetables, then you will be missing out on a lot of fibre intake, which can lead to digestion issues and other health-related issues.
If you drink green juice as a supplement to eating fruit and vegetables, or find another way to increase your fibre intake, then you should be fine to do so everyday.
Make sure you regulate the quantity of green juice you drink each though, since too much oxalic acid - which green vegetables have in abundance - can harm your body in the long run.
