High Protein Banana & Rhubarb Loaf

High Protein Banana & Rhubarb Loaf

Protein powders are often used by individuals who are trying to ‘bulk up’, however they aren’t essential. When protein powders are taken at the right time i.e. before or after a resistance work-out, they can help gym go-ers to increase their absorption of amino acids (the break down of protein) and ultimately achieve their required daily intake of protein, which can be as high as 1.7-2g of protein/Kg body weight – this is much higher than what is recommended for the general population: 0.8-1g/Kg body weight.

This super tasty protein loaf can be enjoyed as a part of your lunch or as a snack between meals. It’s low GI (glycaemic index) and with added protein it helps to boost satiety (fullness) too! Oh, and you DON’T have to like rhubarb to like this recipe!! – honestly!

    This is such a gorgeous loaf cake! Very easy to make and tasted great warmed up with greek yoghurt, a drizzle of honey and crushed walnuts as a desert 🙂 love how healthy it is as well.

      That’s great to know thanks Tony! I would be worried that it would be a little dry but clearly not – don’t worry though if you don’t like rhubarb (I don’t!), as you can’t taste it in the final recipe! Thanks for commenting 🙂 x

    Beautifully moist loaf. Tasty, fruity, nutty, love it! I actually substituted the rhubarb for tinned pumpkin (200g) and added a handful of chopped dates instead of sweetner, and because I’m a sucker for dates! Absolutely delicious. Thanks Nic 🙂

    I am allergic to bananas so decided to make an apple and sultana loaf… I stewed some apples with a stick of cinnamon and a tablespoon of agave, then added some Ella’s kitchen apple purée and some sultanas to the mixture. It is delish!! Nice and sweet too 🙂 will use less wet ingredients next time as it was a bit sticky. Definitely a favourite tho!
