Formulating fiber-rich foods
By Jennifer Nelson, M.S., R.D. and Katherine Zeratsky, R.D.
Gritty drinks and giant pills used to be the only way to supplement the fiber in your diet. Now there are many more appealing options for getting extra fiber. Indeed, fiber seems to be in just about everything — from yogurt to white bread. Have you checked the ingredients on some of these "high-fiber" foods? If so, you've probably seen chicory root fiber — also called inulin — listed as one of the ingredients.
Inulin has health benefits similar to those of fiber in fruits, vegetables and whole grains:
- Prevents constipation
- Helps maintain healthy balance of bacteria in the colon
- Lowers blood cholesterol levels
But why is inulin added to so many foods? Because it adds fiber without adding unwanted taste or texture. Inulin also has the advantage of having a smooth, creamy feeling in our mouth like fat. So food manufacturers can use it as a fat replacement in ice creams, margarines and dressings. With these properties, it sneaks past us as undetected fiber in yogurt and other foods.
Sounds good, right? Sure, but you still need fruits, vegetables and whole grains in your diet. These whole foods offer much more than just fiber. They're rich in phytonutrients, antioxidants and other health-promoting, disease-fighting nutrients that you don't get from "extracted then added" fibers such as inulin.
What do think of food manufacturers finding ways to add fiber into any and all foods? Are these foods part of your diet? Or are you more traditional? I confess that I'm not planning on giving up my real fruit and yogurt breakfast any time soon.

I found that foods containing inulin cause severe stomach upset for me. I wish it were clearly labeled on processed food packages [as items like nuts or gluten are]. Also the amount would be helpful to know. I am of Eastern European descent and have fructose/fructan sensitivity. Because of hidden irritants like this I am buying and eating less and less processed foods.

I have had horrendous constipation in the last month or so - so much so that I though I was going to end up in the ER with them extracting it from me because I could not physically move my bowels. At the same time, I have been batteling constant stomach cramps and aweful gas. I never knew about Chicory or inulin or that they could be the cause of some of the belly pain I have had. I try to eat healthy, but can very easily fall off the wagon and lean towards the crappy food. However, I am desperate to be able to move my stool more than every 4-5 days, so I would try anything! Sorry if this is TMI...but I am very appreciative of any thoughts, ideas, perspectives that could help me out.

Inulin is a prominent ingredient in the trader joes soy milk I purchase and drink regularly. Is it added to liquid products as a thickening agent and to make the product "creamier"? I am currently researching purer brands and will probably switch back to organic milk with cream on top! Delicious and bottled in glass just like the old days when it was delivered to the front porch of my home early every morning.Purely!

Inulin is destroying colons all across America. It is a very destructive product.

Inulin nearly killed me. I've always had a problem with large quantities of onions, but didn't know why. Because of the low-carb craze, manufacturers put it in EVERYTHING. I was sick for three years without knowing why. I would bet money that the rise in IBS coincided precisely with the introduction of inulin into processed food.

As a meat and potatos person and the fact that many vegetables give me an upset stomach, I was able to lose 40 pounds with fiber products. I went from 1 gram of fiber to an average of 25 grams of fiber a day. Slamming 9 grams of a yummy Fiber One carries a price but with the anti gas products like beano etc you can reduce or stop the symtoms. For quick snacks on the go, it is way more nitritional than junk food. I add the inuit powder to foods and eat high fiber bread and cereal. I am very greatful for nutritive options in convenience foods like bread, cereal and fiber bars.

All very interesting, but I have another question. For many years I have been taking psyllium (matamucil), cinnamon, niacin and omega fish oil to keep my ldl steady at 100. I cannot tolerate statins of any form or Zetia. Several months ago I discovered the triglyceride-lowering effects of inulin, so added two teaspoons of it to my regular regimen. My recent blood panel had my ldl up to 115. Now I wonder whether the inulin is competing with the psyllium and reducing its ldl-lowering effects. Is there any supporting research on this topic? Thanks. MEL

I HAVE BEEN TAKING MIRA LAX EVERY DAY PER MY DOCTOR'S advise..It does help sometimes but now I have been having terrible stomach pains. I don;t know if it is related to the miralax or if it is something else. This is a horrible way to live. I just don;t know how people do this. It has gotten me so depressed. I have no idea where to turn. I just would like some relief.

Fiber bars with chicory root are the greatest processed food innovation since sliced bread. After 15 years of chronic constipation and loads of fiber supplements and so called high fiber foods, plus Miralax, the fiber bars did the trick by causing more bulk in my stools.

I WAS ADVISED BY MY DOCTOR TO TAKE MIRALAX EVERY MORNING FOR CONSTIPATION. AT FIRST IT WORKED GREAT, NOW AFTER SEVERAL MONTHS, MY STOOL IS SMALL. I DO NOT GO EVERY DAY AND I AM HAVING SEVERE LEG CRAMPS. I READ THAT ORAL OSMOTICS CAN LEAD TO ELECTROLYTE IMBALANCE, WHICH INCLUDE CALCIUM, MAGNESIUM, SODIUM,CHLORIDE, POTASSIUM,( I AM ALREADY TAKING A POTASSIUM PRESCRIPTION), REGULATE MUSCLE CONTRACTION, HEART RHYTHM, NERVE FUNCTION, FLUID BALANCE AND OTHER BODY FUNCTIONS, AS WELL HAS ABNORMAL HEART RHYTHMS, WEAKNESS, CONFUSION AND SEIZURES. GEE, THE DOC. SAID IT WAS SAFE!

I think that products that have added inulin or chicory root extract should carry a warning label. It may have some health benefits but it also can cause problems for some people. I bought a new kind of granola and my son ate it for a few days and had severe lower abdominal pain. He finally figured out it was caused by the granola, which we discovered contained inulin. I can eat this cereal if I am really careful to just have 1/2 cup or less. If I eat more, the same thing happens to me and it is very sharp pain that doubles you over. I can eat other high fiber foods without inulin or chicory seed extract and have no problem. My son and I are healthy. I would think that if someone with health issues had this happen to them, the effects would even be worse. So, beware. I really read labels to check for this stuff now.

I think it is great! We Americans are getting fatter & fatter. We need anything that will help us stop that. Fiber helps by filling us up, curbing appetite, keeping the bowels moving, and slowing down the digestion of sugar... or so i've read. (hard to know what to believe any more).

I am very thankful for products with Inulin for my gluten free diet. I eat very well, but it's great to have something to take with me on vacation or away from home. Especially KIND bars, they are my favorite by far!!!

Kneading dough is a very important part of making any sort of bread. Well kneaded dough will result in better bread. Adding water in small lots, knead your dough and keep going till it's soft and smooth. I never tire of poking a ball of dough, marveling at it's soft and pliable texture. Every once in a while press down on the dough with the heel of your palm and keeping the pressure firm, spread the dough by extending your hand forward. This will result in the dough getting thinly spread on to the utensil or board. iron rich foods

Why is that my stool was black after consuming 'fiber max' , a kind of powdery fiber supplement. Or is it because I had a serious problem with my intestinal organ.Thanks.

I noticed that most of the comments here are from people who already eat very healthy. Even the authors of the post note that they already eat healthy--real fruit and yogurt for breakfast. The products that are receiving added fiber are not for people who are already eating 5+ servings of fruits and veggies and only eating whole grain. They're being made for the people who don't do that. If we can help someone who only eats things that taste like candy bars get more fiber in their diet, that's awesome. If you're already ridiculously conscious about eating fruits/veggies/whole grains, why are you buying fiber-added products anyway? If you're eating lots of fiber and still having problems with constipation (due to medication, age, etc.) try adding a laxative to your routine. MiraLax taking at a fraction of the recommended dosage will help you tremendously (start at 1/4 and increase until you're happy with the results). If you're already getting enough fiber, more fiber is not the answer.

In response to Donna, I too have to be very careful with high fiber foods (lima beans,black beans,etc.) and fiber supplements (Metamucil). Very difficult to manage constipation/slow transit time.

I find that these "high fiber" products actually cause constipation for me! I tried one that I stirred into water or drinks, starting with a small amount once a day and very gradually increasing it over time. My bowels slowed more and more as the amount increased! I stopped, and it improved. Tried a yogurt product with probiotic and it helped, but gradually stopped helping so I tried the one with fiber and it was immediately worse. I am 56 and hormone changes are slowing my bowels. I eat 4 - 5 servings of fruit and vegetables a day, only whole grain, drink water lots, exercise and still way too slow. Has anyone else had these products make the situation worse? I would rather just add more whole food with nutrients, but I have to watch the calories for the day, and everything adds up.

Apple cider vinegar, about 2 teaspoons in a large glass of water, twice a day does it for me. I have had constipation for years, and this is the best solution I have found. I took Activia yogert for a while, but it was costly and seemed to be less active with time. The water may be helpful, because I don't get thursty often and have trouble drinking 10 glasses a day.

Do vitamins contribute to constipation? I take a multiple plus extra vitamin D & calcium from dr. orders. I take ginkgo for help with memory. Are these working against me?

Where are you getting your info? All of what I'm reading is that these "isolated" fibers do not provide the same health benefits as "intact" fibers. Can you point me to a scientific study that PROVES their health benefits?

As someone who has lost 40 pounds on Weight Watchers in 6 months, I love the extra fiber added to Fiber One bars and other tasty WW snacks. WW points are based on calories, with fat raising points and fiber lowering points. However, I do not depends on prepackaged, inulin-fortified foods to lose weight. It's great when I want something yummy but that isn't all that bad for you (Fiber One bars are only 2 points!). Some people do depend on them, but I love to eat (hence I am on WW) and have totally changed what kinds of foods I buy and keep around the house so I can eat more in a day. Getting nutrients as they occur naturally is great, but sometimes when it comes down to it, it can be beneficial and/ the lesser of the evils.

A lot of people (me included) get major gas from chicory root. I've been vegetarian and almost vegan (am allergic to eggs and dairy) for decades and am used to a lot more fiber than typical carnivores, and also routinely take acidophilus-type supplements. So even if eating a lot of beans, I don't usually get much gas, my body knows how to deal with it. But chicory root is just too much for some reason. They're putting it in my favorite multigrain bread now to get the fiber up to some insanely high value, so I head toward the 100% whole wheat instead (hopefully they won't mess with that, it's "low fiber" in comparison now). Some wonderful vegan "ice cream", Purely Decadent (yes, it lives up to its name), has 5 grams of fiber in 1/4 pint because of the chicory. If I pig out on that (too, too easy to do), I'll get horribly persistent and painful trapped gas for days that only slowly breaks up with a lot of help from activated charcoal capsules... I was just reading elsewhere reports by people having gas problems with the Fiber One bars, which though tasty list chicory as the first ingredient. So be cautious! Probably best to introduce chicory-containing food slowly despite the attraction of quick high fiber. Of course, adding fiber to your diet should be done gradually anyway, but my experience (as someone already used to a lot of fiber) shows that chicory is something different than usual sources of fiber.
