A refreshing, immune-boosting Winter smoothie

I created this immune boosting smoothie because I much prefer to prevent illnesses than have to deal with being sick and everything it entails. Especially during cold and flu season.

Just the thought of cold & flu tablets and antibiotics makes me cringe. Antibiotics really mess with our health by killing off a lot of our good gut bacteria. And a lot of cold and flu medicines are pretty much just glorified sweets.

Drinking this immune boosting smoothie 2 or 3 times a week will help you keep those Winter bugs at bay. Keep your defences up by eating a diet full of fresh fruit & vegetables, whole grains and healthy fats.

Check out my list of immune boosting foods in this post about NATURAL COLD & FLU REMEDIES and give this smoothie a try.

I also drink lots of green tea, and Rooibos tea for their anti oxidant properties. Read about all of the benefits of drinking Rooibos here: WHY SHOULD YOU BE DRINKING ROOIBOS TEA?

How to make the immune booster smoothie

This smoothie is made with just five ingredients: spinach, orange, grapefruit, pear and ginger.

Remove the peel from the orange and grapefruit, roughly chop the fruit and veggies, and blend until smooth.

Use any variety of pear or grapefruit. I usually use a William pear and a ruby grapefruit.

If you prefer a sweeter tasting smoothie, add another orange, or just use half the grapefruit.

This recipe makes 2 serves, and you can keep it overnight, in a sealed container in the fridge.
