These Fiberful bars have no added sugar (or fake sugar, which I passionately avoid) and are made from natural ingredients (including natural dried fruit, flaxseed which is high in omega 3, and fiber). They are also super cheap! The only possible drawback of the bars is that they have added natural fiber in the form of inulin (you can read a good article I found about inulin here), which, is believed to cause gas (like most fiber) in some people when eating large quantities of it.
I also have another favorite natural "smooshed" fruit bar which I buy at Whole Foods called Fruitabu, which I'll blog about soon. Unfortunately, it is 1 WW point instead of 0 (although it is only 40 calories, it has no fiber), but is worth talking about for those of you who aren't counting points.
Enjoy your Trader Joe's Fiberful Fruit Bars!
A few other low calorie bars I've blogged about worth checking out: Gnu Foods, Clif Z Bars, Luna Tea Cakes, Fruitabu, Attune probiotic bar, Clif Z Bars, and Figamajigs.
