“You know I see too that there's a lot of free apps out there right now. Um, there's like Seed Oil Scout, Um and Trash Panda where you can scan everything. So people can go and scan everything in the grocery store. And it's called Trash Panda. That's actually kind of a cool name. I know. It's such a cute name. I love it. That's catchy. Trash Panda. Great job. And so you scan the QR code on any food label. Exactly. And it'll tell you and then it'll tell you it rates it and then they tell you all the ingredients that are red flag why they're red flags and then it'll it'll give you um alternative options.”
