Can green smoothies give you stomach issues?

Can drinking green smoothies give you issues? For some it can be an uncomfortable experience and also, at times, for the people around them. Our Nutritionist Sam answers this for you and runs through some of the potential solutions for an upset tummy as well.

So you whipped up an awesome tasting green smoothie, and chugged it down.

Next thing you know, your tummy isn’t happy.

Whether you’re feeling bloated, gassy, or if you’re going to the toilet more often than you’d like, the green smoothie might be the cause.

But that doesn’t mean that you have to give up your green smoothie!

After all, green smoothies are generally healthy, and can still be an integral part of a balanced meal plan.

Here are a few reasons why a green smoothie might give you stomach issues, and what you can do to work around the problem.

A sudden increase in fibre intake

The great thing about smoothies with plenty of greens is that they are a great source of fibre.

Greens contain insoluble fibre that add bulk to your poop, and soluble fibre that feeds the good bacteria in your gut.

But if you’re not used to eating a good amount of fibre, hitting the green smoothies hard can lead to some tummy troubles.

Both soluble and insoluble fibre can lead to bloating, discomfort and diarrhoea if the gut isn’t used to it.

So if your green smoothie has 4 different veg and a couple of serves of fruit, you sometimes might end up feeling worse for wear.

The fix?

Start slow and increase your fibre intake in increments.

If you don’t usually have fibre-rich foods, just add one serve of veg and one serve of fruit to your smoothies.

After a week or so of smoothies, add another serve of veg to this and work up from there.

Sensitivity to fructose or FODMAPs

Sometimes, you can have a sensitivity to specific carbohydrates or sugars in fruit and vegetables.

Depending on which ingredients you’re adding to your smoothie, a fructose or FODMAP intolerance might be to blame.

FODMAPs are a group of carbohydrates found in many healthy foods.

For the average person, they’re not a problem, but for some people they are difficult to digest, and can lead to digestive symptoms.

Some smoothie ingredients that are high in FODMAPs include these:

  • Apples
  • Cherries
  • Mangos
  • Nectarines
  • Peaches
  • Pears
  • Plum
  • Watermelon
  • Cauliflower
  • Dairy products
  • Soy milk
  • Honey

The fix?

If you suspect FODMAPs are a problem for you, it’s best to seek advice from a nutritionist.

They can confirm whether FODMAPs are the issue, and give you guidance about your next steps.

In the meantime, you can stick to low-FODMAP smoothie ingredients such as cucumber, kiwifruit, pineapple, grapes and almond milk.

If you can’t live without one of the listed smoothie ingredients, halve the serving size and see if that minimises your symptoms.

Sweeteners in green powders or other ingredients

It’s great to add in some supergreens like spirulina, chlorella and wheatgrass into your green smoothie.

But some green powders contain sweeteners such as sorbitol and mannitol that can irritate your digestive tract.

These sweeteners are also commonly used in quite a few other types of powder supplements such as protein powders.

The fix?

Switch your powders over to a brand that contains stevia or monkfruit, or ones that are even completely unsweetened.

If greens continue to give you issues

Remember to always be sensible when it comes to your health concerns.

If you do continue to experience digestive issues when you’re drinking green smoothies (or even when you’re not!), you should be seeking professional advice as soon as you can.

It’s better to be safe than sorry when it comes to your digestive health!
