The FODMAP Diet: Some Common Sense

 

As with any restrictive diet, caution must be used to avoid nutritional deficiencies.  That is why it is important to pay attention to a registered dietitian when embarking on any diet that restricts certain food groups. If a dietitian is not available, seek out the advice found in the following article from an expert on the FODMAP  diet. The best advice is if this diet approach does not produce any positive results, it may not be for you.

The Complexities of Food Sensitivities

Most people when confronted with a negative reaction to certain foods simply say “I’m allergic to” (fill in the blank). Self-diagnoses and treatments are common and result in the development of unnecessary restrictive diets and disordered eating.

The following article aptly attempts to wade through  the confusion and complexities of food allergies, intolerances or sensitivities in order to increase some understanding of what to do about these poorly defined and understood afflictions. Even many physicians fail to differentiate the confusion surrounding the problems.  We now have food labels that support a long list of “NO’s) – gluten, wheat, lactose, soy, nuts, high fructose corn syrup, antibiotics, hormones, preservatives, etc. etc.  No wonder people are challenged even when going to the supermarket.

Food allergies can be life-threatening, so it is important to identify which food(s) are the culprits. Keeping a food and symptom diary or beginning an elimination diet with oral challenges should not be attempted without professional help like your physician, physician assistant, or registered dietitan/nutritionist (RDN) who specializes in food intolerances.

The article is a long read, but if you think you may have any food sensitivity, it may be worth the time spent before any self diagnosis or treatment is undertaken. Search this blogsite for information on food alleriges, intolerances, FODMAPs and gluten or wheat intolerance disorders.

Processed Foods and Health

BIG FOOD

When discussing healthy diets, the advice is often to stay away from processed foods. Actually, this is almost impossible since most foods undergo some form of processing to ensure food safety of perishable foods. I think that a better message would be that we should attempt to avoid ultra-processed foods, many of which have high levels of sodium, fat or sugar. At a glance, these foods are easily identified by their extremely long ingredient lists. A recent report from the University of North Carolina (Chapel Hill) found that more than 60% of the food purchased annually in the U.S. is highly processed, This trend will continue as long as consumers buy these boxed and bagged products that fill our landfills and detract from environmental responsibility.

The highly processed foods are those found in the center aisles of the supermarket and include frozen and ready-made meals, cereals, snacks, cheese spreads, and other packaged items. These foods are commonly filled with additives or preservatives to improve flavor, texture and extend shelf life.

What effects can these foods have on our health and why?

Obesity, Metabolic Syndrome, Diabetes, Cardiovascular Disea  

Obesity has been associated with our excessive intake of sugar and linked to a plethora of adverse health issues that include metabolic syndrome, diabetes type 2, and cardiovascular disease. If you look at the ingredient lists, you may find on some products sugar listed by many names. Sugar means sucrose but is contained in brown sugar, granulated, raw or powdered sugars. However, your sugar vocabulary should include high fructose corn syrup, invert sugar, dextrose, glucose, maltose, lactose and fructose. There is also corn syrup, honey, molasses, malt syrup, sugar syrup, and fruit juice concentrate. Some research suggests that sugar triggers the same sense of pleasure and cravings within the brain that also triggers drug addiction.

Inflammatory Bowel Disease (IBD)

Inflammatory bowel disease encompasses two major diseases: ulcerative colitis and Crohn’s disease. The blame may go to additives called emulsifiers. They are found in many processed foods like breads, peanut butter, cake mixes, salad dressings, sauces, yogurt, pudding, processed cheese, and ice cream. Emulsifiers function to keep water and oil mixed in food products that contain ingredients that would normally separate.

Emulsifiers used in processed foods function in the same way as those found in household soaps or detergents.  When mice were fed diets high in common food emulsifiers, they developed diseases similar to ones already discussed (obesity and metabolic syndrome, as well as IBD. The conclusions of the authors were that bacteria in the microbiome  affected the mucus protective layer that separates them from the intestinal wall, similarly to how a detergent works to remove dirt in industrial applications. It is thought by some that this process causes an inflammatory reaction that may contribute to the incidence of these diseases.

Autoimmune Diseases

Autoimmune diseases are characterized by when the body attacks its own cells. At last count, there are about 100 of these diseases and the more common ones include; diabetes type 1, multiple sclerosis, rheumatoid arthritis, Crohn’s disease, and Hashimoto’s thyroiditis.

The intestine is lined with epithelial cells that function to serve as a protective membrane to prevent  toxins, harmful bacteria, or other substances called antigens that could cross this barrier and cause an immune reaction in the body.  Intestinal permeability is a term describing the control of material passing from inside the gastrointestinal tract through the cells lining the gut wall, into the rest of the body. (Wikipedia). The media refers to intestinal permeability  as “leaky gut syndrome,” but is debunked by many in the medical profession, due to a lack of quality research to support it. Nevertheless, the possibility of emulsifiers and other processed food additives conceivably could damage or affect intestinal permeability leading to an autoimmune disease. Other additives that could affect this permeability in addition to emulsifiers are glucose, salt, organic solvents, and gluten and all are used in processed food products.  (WebMD, Digestive disorders/leaky gut syndrome).

Colorectal Cancer

Colorectal cancer has been associated with processed meats like hot dogs, sausage, deli meats or any other meat product chemically treated with preservatives. This also can include red meat consumed daily. The chemicals used have been linked to have carcinogenic properties.

The link between sodium nitrites and cancer may be the culprit. Processed meats are manufactured using sodium nitrite. During the process of cooking certain meats, sodium nitrites combine with naturally present amines in the meat to form carcinogenic N-nitroso compounds.

Eating a diet of primarily whole foods rather than reliance on highly processed foods may help prevent some of the common diseases of our culture from food intolerance to cancer prevention. Processed foods may have subtle effects on our bodies that are difficult to assess or determine. Listen to your brain-gut reactions that may help you identify some of the effects that some unknown additive may have on your health. Digestive distress can be an indication that your body is sensitive to a certain ingredient and can be simply alleviated by consuming fewer ultra processed foods.

Gluten-Free?

 

The recent gluten-free food fad has some nutritionists concerned. When people eat gluten-free foods, they may be missing some important nutrients. It is generally recommended that if you do not have celiac disease, you do not need to avoid gluten. However, some people have given up wheat and other grains due to a real or perceived benefit. Many report that their digestive symptoms improve or “they just feel better.” Non-celiac gluten sensitivity or gluten intolerance has been suggested but as yet there is no definitive test for its diagnosis.

Research has shown that avoiding FODMAPS can help people with irritable bowel syndrome (IBS). Wheat and other grains (rye, barley) (containing gluten) are sources of fructans that aggravate symptoms of IBS. So it is advised to eliminate these grains for a time from the diet to see if symptoms improve. See a previous post HERE.

If you choose gluten-free foods, you should definitely read the Nutrition Facts Panel as well as the ingredient lists.

Sourdough Bread?

If you are avoiding wheat due to real or perceived intolerance to gluten, you may give sourdough bread a try. It is not recommended if you have been diagnosed with celiac disease, since it still contains gluten.

Avoid commercial sourdough since most will not be authentic. Try local bakeries and ask for a list of ingredients. Or you can make your own (with some patience and time) from a recipe found HERE.

Is Gluten-Free Merely a Fad?

Gluten

Going gluten-free is becoming more mainstream.  There appears to be more people avoiding gluten without having a celiac disease diagnosis. Gluten-free is appearing on restaurant menus and on food labels in supermarket products. Why is this occurring? The following article addresses this issue and gives us the facts.
