Correct me if I am wrong, but I have an issue with "liquid" food.

My concern with products like Soylent and Huel is whether the nutruients they claim to provide are actually absorbed by your body.

Solid food that has been liquidised is not the same as solid food: nutrient absorbption is affected by rate of digestion - more solid food, especially if it is fibrous, gives our bodies more time to absorb nutrients.

It's the same way a fruit smoothie is actually worse for you than just eating the solid contents (disregarding the insane sugar content you would consume).
