The ZOE personalized nutrition program scores hundreds of thousands of products (you can scan barcodes with the app). If you have poor glucose and fat control, you're not going to find many high-scoring pre-prepackaged snacks because, well, they tend to represent all the things we don't want to eat: they're extremely processed, often high in sugar and/or the hydrogenated fats, and very salty. And one of things ZOE emphasizes is that you eat a diversity of gut-healing plants. You even get a plant score every day!
That said, you won't eat this way for very long if you feel deprived. So, when I do find snack-like things that feel like a treat and add some crunch, I keep a record! I'm sharing my finds here so that you know they exist. (Disclosure: Some of the links on this page are affiliate links.

First, Choc Zero has two products that are gifts to those of us unable to eat sugary things. This is how their delicious hazelnut spread compares with traditional Nutella: 
If you love Nutella, the good news is that you can eat it, as long as you combine it with the right things. The ZOE app helps you do figure that out—nothing is off limits when you eat this way. But when you want smooth, chocolatey deliciousness, the Choc Zero Keto Spread is your friend and it comes in four flavors - the dark chocolate is my favorite.  

If you're a nut-butter and jam person, then get excited about Choc Zero jam, available in strawberry, raspberry, and marmalade. It's delicious and this is how it scores: 


It scores like berries, but tastes like really good jam. 
Last item on the sweet list are these delicious candied pecans by Trader Joes! And again, the ZOE score will make you do a happy dance: 
You should obviously NOT live on sugary things and these nuts are sugary. But they're a perfect partner for a handful of blackberries, especially as dessert. Another thing you start to learn using this app is that eating sweet treats after a meal is a much better idea than having them on their own as a snack. 
If you're on the go and really need a snack between meals, Trader Joe's Teriyaki Seaweed is a great option. Here's how ZOE scores it: 
This snack is also a great way to add sea greens to your diet. The goal is "diversity of plants" and for most people in the US, seaweed doesn't pop up often in regular meals. With my poor blood fat control, it's better to eat this in combination with a meal. But in pinch, I'll eat it on its own.

If you're craving something savory and crunchy, then most parmesan crisps score decently:

But not great for my blood fat so again, I'm definitely not going to eat a whole bag of these. Instead, I love to eat them as part of a meal, like with avocado toast: 
Here's how the whole meal scores ... again, combining foods in the right way makes all the difference:
