Radioactive Smoothie

Are you ready to create your very own radioactive smoothie? It’s one of my simplest recipes. Perfect for a morning breakfast drink on the go or even as a light lunch replacement. I actually had it for lunch today! Yes – I did indeed drink some radioactive material for lunch today.

In case you’re wondering if I’ve lost all my marbles, let me quickly explain what I’m talking about. Bananas are radioactive. And if you’re a scientifically oriented person – I know you’re thinking – “Yeah Raj – so is just about everything else on this planet”. But bananas in particular are quite special in terms or radioactivity. Bananas, as you know, contain a high level of potassium including a small amount of unstable isotope potassium-40 (also known as K-40). Put simply, radioactive decay is the process by which unstable elements (specifically atoms) lose energy and eventually “stabilizes” into a stable substance. Naturally occurring unstable K-40 decays to stable Ar-40 or to stable Ca-40. Thus making bananas radioactive and slightly unstable. (Which might explain the expression – “going bananas”)

In fact – because bananas are radioactive they are even used to describe other radioactive material. There is a term known as Banana Equivalent Dose which was created to express in simple terms the severity of exposure to radiation resulting from things such as nuclear power, nuclear weapons or medical procedures.

Before you start throwing bananas out of your diet, please understand that this dose of radioactive material is really harmless. I only bring it up as a fun fact which I didn’t know about bananas until recently. 🙂 Also if you found this fact entertaining check out XKCD’s radiation dose chart with a breakdown of radiation absorbed by a person from various common sources (such as airplane rides across the US).

Radioactivity set aside, this recipe makes a great breakfast drink or even a quick lunch. Peanut butter and bananas are always a popular combination and this recipe adds to that reputation. I used to have this almost three to four times a week when I first started on the Specific Carbohydrate Diet. It contains some of the basic building blocks for that diet provided you can tolerate nuts. I have tried this recipe with both natural and roasted peanut butter – both are delicious. Just remember to use unsalted peanut butter!

Enjoy!

    Banana and peanut butter is one of my favourite combinations! What a great post – I didn’t know the meaning of “going bananas! I love learning new stuff! Excellent!

      haha.. I kinda thought up the “going bananas” bit. I have heard that saying plenty of times and basically it meant that it meant “going crazy”.. but I liked how the radioactive “instability” also tied into the saying. 🙂
