Understanding the in’s and out’s of fiber

Overly-processed white breads do not contain fiber naturally. So where is this fiber coming from?
Many consumers are buying foods that are fortified with synthetic fiber additives. Food manufacturers, faced with demands to reduce calories, fat, and sodium, while increasing fiber and flavor, are increasingly turning to products like inulin.
Manufacturers have discovered they can chemically manipulate the chemical structure of inulin (a natural source of fiber found in asparagus, chicory root, onion, and garlic) to mimic the tastes and textures consumers want in food. These additives are then used to promote "high fiber" in processed foods. But over consumption of these highly processed additives are actually causing more gastrointestinal problems and sensitivities, causing an array of side effects.
While the food industry is using processed inulin and the "three gram" fiber guidelines as a way to increase their sales of grain-based products, it is important to understand where one can find natural fiber sources.
So, how much fiber does a person need? The American Heart Association Eating Plan suggests eating a variety of food fiber sources with total dietary fiber intake around 25 to 30 grams a day from food.
Dietary fibers are found naturally in plants as well as whole grains.
â€¢ Slows down digestion by delaying the emptying of the stomach
â€¢ Sources include: oat cereal, lentils, apples, beans, and nuts
â€¢ Considered gut-healthy fiber and remains intact when passing through the gastrointestinal tract
â€¢ Mainly found in whole grains and vegetables
The majority of research promoting dietary fibers comes from studies that utilized fiber rich fruits and vegetables. However, controlled intervention trials have shown no proven protective effects of the dietary supplement of wheat-bran fiber as is used and promoted by the food industry.
In fact, many studies demonstrate that excess intake of fiber may actually be harmful, particularly for gut health. Excess insoluble fiber can bind to minerals such as zinc, magnesium, calcium, and iron, preventing the absorption of these vital nutrients, leading to inadequate proteindigestion and reduced pancreatic activity. Thus "the addition of insoluble and soluble fibers to processed foods may actually cause these foods to be even less nutritious than if they were not enriched with any fiber at all!"
It is important to note that natural sources of inulin (asparagus, chicory root, onion, garlic, etc) do have beneficial effects on the body as it promotes healthy guy flora. However, the altered version found in processed foods is not gut friendly.
Byproducts created during the fermentation process of these foods can cause symptoms of gas, bloating, diarrhea, and nausea. The process is very similar by which cornstarch is converted to high fructose corn syrup. Though processing methods can differ among manufacturers, most commercial products use genetically modified enzymes and an intense chemical process.
Supporting the good bacteria in one’s digestive system is important because 80 percent of the immune system is located there and is the body’s first line of defense in terms of immunity.
Supporting healthy gut flora with prebiotics and probiotics can help prevent and/or treat symptoms such as diarrhea, yeast infections, irritable bowel, and indigestion.
Highly processed inulin is not the only culprit of the additive family that can cause stomach pains. With more foods available now that are processed to ensure a longer-lasting shelf life, we as consumers, need to be aware of what these additives are and how excess consumption can affect us.
Reading the labels is one step that can help educate consumers about ingredients added to processed foods.
Chemically-processed foods can wreak havoc on a digestive tract. Get started in the right direction toward making steps to correct and improve digestive health by getting a comprehensive blood test and tissue mineral analysis. By determining deficiencies and toxicities based on blood chemistry, supplemental guidelines and dietary improvements can correct the balance of gut flora and help improve digestive health for the proper breakdown of nutrients.
