It seems like there’s been quite a surge lately in the amount of “healthy” snacks like granola bars, protein bars, even cookies.
A lot of these products have added fiber, which has been proven to be heart-healthy and reduce cholesterol.
The Fiber One brand makes some great cereals with plenty of fiber that are easy to eat. I have the plain Fiber One cereal every morning with my protein powder, which only has 60 calories and almost 15 grams of fiber.
So, I expected good things from Fiber One Chewy Oat Bars.
Fiber One Bar’s Taste
When I opened the package and took a bite, I noticed how good it tasted right away – sweet, chocolatey, and not too chewy.
The oats are held together with something that tastes vaguely like honey, and there is a drizzle of milk chocolate over the top of the bar. It reminded me of other granola bars I’d had as a kid.
I couldn’t really taste the fiber – it was more like eating a candy bar.
I ended up eating all 5 of these bars in one sitting, they were so addictive – which is why there’s not a picture of them (the box got thrown out).
Something about the taste made me crave them.
The Nutrition
The nutritional information was pretty much what I expected – 140 calories, 9 grams of fiber (chicory root), but Fiber One also has 10 grams of sugar.
I guess I should have been expecting that, given how sweet it was. But then I read the ingredient list – these bars contain high fructose corn syrup, as well as hydrogenated coconut oil (trans fat)!
What’s healthy about that?
Sugar: Just like a candy bar, sugary foods spike insulin levels which often results in an energy crash shortly after. High insulin levels lead to fat storage.
Chicory: A lot of people have trouble digesting this type of fiber leading to painful gas.
Trans fat: This has been linked to heart disease, so any product with hydrogentared oils should be avoided. Even if they say zero trans fat, they could still legally have .5 grams/serving. (Fiber One has since removed all hydrogenated oils from their product.)
I see this bar as nothing but a glorified candy bar, and given the ingredients, I probably wouldn’t eat them again.
If you’re more interested in good taste and farting, Fiber One Oat Bars may be for you.
NOTE: This is NOT a paid product endorsement. In fact it’s not an endorsement at all 
That’s a joke, right?
This bar really works for me, but it does cause gas. In fact, this bar keeps me regulated to the point I don’t need laxatives. I will continue to eat these, but may cut back to one a day because of the sugar, gas, and possible bloating.
I love this bar
I’m not sure why it’s being said that there are HFCS in these bars when they include MALTOSE corn syrup. On another note, some complain of stomach aches. I eat so many of these bars and I never get stomach aches and if you don’t like gas then don’t eat a whole box. Problem el o solved. Btw, Chicory Root extract is said to taste similar to fat so that’s partly why it’s so a da tastey e.
HFCS is not safe to eat. It is addictive, causes cravings, and your body does not recognize it as “filling” so you keep eating more and more. It’s all wrong. Anyone who thinks HFCS is safe is believing the big corporation propaganda, which helps them make more money and keep America totally fat (obese) and “happy”.
HFCS is chemically the same as table sugar. There is no evidence that HFCS is any more dangerous than any of the other added sugars we use. There are millions of people who consume HFCS who are not obese.
Sorry, worst abdominal pain.
I will never eat a Fiber One bar again. I had the worse abdominal pain. Why is no taking these things off the market?
they haven’t been taken off the market because people who daily consume fiber don’t notice these abdominal cramps that people are talking about. Take it down to half a bar, get used to the fiber and then see if you’re cramping. Notice these only contain a third of the fiber the DRI suggests so imagine 100%
No Tina, it’s actually because some people don’t tollerate the type of fiber used in fiber one which is chicory.. I eat a lot of fiber, but if I have the slightest bit of chicory, it’s over.. my body never gets used to it.
