My body needed a few weeks to adapt to Queal, so it's preferable to start slow at first and avoid eating it thrice a day. After my time of adaptation however, i no longer had any troubles with it, and even felt better than with "normal" food.
Overall, i'm very happy with my purchase and plan to stick with Queal in the future. As someone that don't have much time (and will) to cook, this is a blessing. Also, definitely healthier than the prepared food i used to eat before, i even lost a little bit of weight.
