Thank you! I think what you experience is actually intended, though somewhat poorly communicated: Food can only be picked up if it is on the right "side" of the strip, i.e. in front of the grid. There's actually a color difference between the frontside and the backside of food, but I admit it is extremely subtle when post-processing is enabled. Anyway, if you travel along the strip for a while, you'll find a version of the food that you can pick up.
