Q & A: Green Smoothies on the Go AKA How Long Will My Green Smoothie Last?

Ever since participating in Green July last year (wow time flies!), I've made it my mission to continue having at least one green smoothie per day. Usually I have enough time in the morning to blend up a little green concoction and drink it for breakfast in the comfort of my own home- no weird looks or funny faces from anyone 😛

However on busy days or days that I start work early it can be challenging trying to fit in time to prep, blend and drink the daily green good stuff. Now I know I'm not the only one who suffers from this little dilemma and thanks to a email from a lovely Wellness WA reader I've got some answers for all your green smoothie on the go questions!

How long will a green smoothie stay fresh for after I make it?
Most green smoothies will stay fresh in the refrigerator for up to 24 hours, but you will lose some nutrients as it sits in the fridge. If you're rushed for time in the morning, making the smoothie before bed and storing it in an airtight bottle (glass is best) should see it stay fresh for breakfast the next morning. Another option would be to prep all the ingredients and put them in a zip lock bag, which can then be stored in the freezer overnight. That way in the morning all you have to do is add water or milk, blend and go!

Can it be kept in the fridge at work and drunk at lunchtime?

Drinking green smoothies fresh in the morning is best, but if you want to drink it around lunchtime at work that's totally fine too! Again just make sure it is properly stored in an airtight bottle. If water separation occurs, just shake it around a little first before you drink!

What fruits are best to use in a smoothie that won't be consumed immediately?

Smoothies containing bananas should be consumed immediately as bananas degrade more quickly than any other fruit (you may notice a weird change in the color and taste of your smoothie!). Other fruits and ingredients that are often included in green smoothies should stay fresh for the whole day. Berries are best!

    What are the healthiest greens to put in a green smoothie? I’ve seen the recipes so please don’t link me to that.

  2. Kavisha says:

    Hi Nicky

    Any greens that you put into your smoothie are going to be highly nutritious. My favs would have to be spinach and kale. Both extremely good for you.

    Other highly nutritious greens include rocket, swiss chard and chinese greens such as bok choy. These have a stronger flavour though so may take a little getting use to 🙂

    If you were to make a large batch of green smoothies at the beginning of the week, freeze them, and move one serve from the freezer to the fridge each night for breakfast the next day, do you think they would lose much nutritional value?

  4. Kavisha says:

    Hi Tobie

    Great question!

    As soon as fruit and vegetables are blended they oxidise and they start to lose a lot of their nutrition so it’s probably best to drink them as soon as you can. I would recommend chopping all the ingredients up and putting each serving in a ziplock bag in the freezer (so you’ll have 7). Then in the morning all you have to do is add the frozen mix to water/milk, blend and go. A lot quicker and saves nutritional value 🙂

    Have you got any recommendations for a good blender (that leaves no lumpy bits behind! can make things a bit … chewy haha!)? Thank you!

    Hi Rhiannon,

    I use the Breville Optiva and it’s pretty good!!! You want something with strong steel blades, this one is about $80 and i recommend it.

    Another tip is to blend your greens before you add and blend the berries / banana / other fruits and bits and pieces. Add the greens and some liquid then blend that up, results in a much smoother consistency.

    Hope that helps! X
