I tried this gum after Trident cinnamon became hard to find a couple of years ago.  (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.)  I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back.  It does last a long, long, long, time.  Unfortunatley, as other reviewers noted, it has become very hard to find in stores.  Trident cinnamon is everywhere but now I don't want it.  Amazon saves the day again.

I have a confession to make:  I had one of these bars and a cup of coffee for breakfast, and it was actually not bad.  But the Amazon stars say "I love it" for 5 stars, "I like it" for 4 stars and "It's okay" for 3 stars.  So, I give it 3 stars.  I personally felt the coconut flavor was stronger than the chocolate flavor and I'm not a big coconut fan, but I am a chocolate fan.  It wasn't terribly sweet and I rather think I would have liked it a little better if it had been sweeter (but not too sweet - I'm kind of picky that way).  I liked the oats and the "gluten free"-ness of it.  I don't eat gluten, so that makes bread/bagels pretty expensive.  These worked out best for breakfast, although I think I used it as a going to bed snack a couple of times.  So, just for fun, I got some nutritional information from 1) Pamela's Oat Chocolate Chip bars 2) some unsalted, dry roasted peanuts and 3) some non-gluten gingersnaps.  1) 1, 1.41 oz bar  -had 9g fat, 15 mg cholesterol, 130 mg sodium and 2g of protein. 2) 1 oz (40 nuts)  -had 14g fat, 0mg cholesterol, 0mg sodium and 7g protein. 3) 5 cookies (30g or 1.06 oz)  -had 6g fat, 0mg cholesterol, 85 mg sodium and 2g protein.  I think that each of these snacks might serve at one point or another.  If you are looking for high protein, then neither the cookies or the Pamela's bars would do the trick, confirming that the Pamela's bars would be more of a snack than a meal.  So don't eat one of these with coffee for breakfast.  Ever.

These are better than the usual canned fish filets, tastier, and not dry.  There are no bones or skins.  I worried about Mackerel but they are much nicer than, say, kippered herring filets or sardines in oil.  It's easy to pour off the olive oil if that is a worry, but you'd be losing something that is also tasty.
