The beating heart of all meal replacement shakes is the ingredients, and as such the biggest differences tend to be found in the choices made here. You can see this as there are only a few shared ingredients between the two:
Rootana’s formula is a blend of oat flour powder, pea protein isolate, golden milled flaxseed, sunflower seed oil, sunflower lecithin, coconut sugar and then some minor ingredients such as potassium chloride, magnesium phosphate, guar gum, xantham gum, and salt.
Yfood has some different options, but we’ll be comparing its vegan powder today. This formula contains vegetable proteins (soy, pea, sunflower) vegetable oils (sunflower, rapeseed), rice flour, soluble corn fibre, modified starch, waxy corn starch, quinoa flour, gluten-free oat fibre, tapioca starch, acerola powder, blueberry powder, maltodextrin, colour carotenes; salt, sweetener sucralose.
First of all, you can see that there are a lot more ingredients in Yfood, which may intuitively feel like a better deal but is more often than not a sign that the formula is a bit unfocused. Rootana manages to hit all of its macros well with just 11 carefully selected ingredients and doesn’t have to rely on anything artificial to do so.
The use of maltodextrin can be an issue for some, as it has a higher GI score than table sugar. This means that the powder can cause a spike in your blood sugar, making you more likely to experience a sugar crash and all of the lethargy that is associated with this. Repeated spikes in your blood sugar can cause heart problems, kidney problems, and problems with your eyesight [1] and over time will increase insulin resistance [2].
