Reasonably tasty, not too bad nutritionally and not too sweet
I'll be honest with you, I'm not really sure what these things are. I didn't know what they were when I bought them, and I don't know what they are after having eaten a bunch over the last week. This is like some kind of next-wave breakfast treat stuff happening right here.
What are they? Well, you eat them for breakfast. According to the Nabisco website, Belvita Breakfast Biscuits "are specially baked to release energy regularly and continuously in your body." Which is either some creepy food science, or a bunch of marketing BS. Which one, I leave it to the reader to decide.
One thing I can answer: these are "biscuits" in the British sense. Meaning, cookies. Not a very cookie-like cookie, to be sure. Their closest relation is probably the animal cracker. They share a similar taste and crispy, crumbly texture. Imagine an animal cracker crossed with a graham cracker, and you're getting pretty close.
I bought the Golden Oat flavor, which meant that as you eat it, whole oats kind of get stuck in your teeth. But oats are good for you, so it's okay to eat cookies for breakfast, right?
Nabisco touts the portability of these cookies, and I will hand it to them: these are one of the easiest breakfast foods to transport and eat. A lot of breakfast options are either greasy or sticky, neither of which is something you want to have to deal with during your morning commute. These cookies are dry - perhaps a little bland - but I'm not one of those people who likes a very sweet and flavorful and exciting breakfast. Frankly, every day for breakfast for the last two years I have eaten a bowl of quick oatmeal (whole oats; microwave two minutes).
Nutritionally, these aren't too bad. A pack of four cookies clocks in at 230 calories, 8 grams of fat, and 4 grams of protein. That's comparable to the next closest breakfast food, a Nutrigrain bar, which averages 240 calories, 3 grams of fat, and 2 grams of protein per two-bar pack. And Belvita crackers are not super sweet, the way that Nutrigrain bars are, with their jammy middles.
I mean, there are probably better options for breakfast, nutritionally speaking. But you gotta eat breakfast, and these are easy to tuck in your pocket on your way out the door. As far as breakfast options during the work week goes, these aren't as bad as some, they have little potential mess, and they don't require cutlery (like yogurt does).
