Gluten is a family of storage proteins found in various grains such as barley, rye, and wheat. Gluten is responsible for the soft and chewy texture of pastries and baked items. It also retains the moisture in bread, pasta, and cereal.
Gluten intolerance and gluten sensitivity are two terms used interchangeably to describe a condition where the body recognizes gluten as an ‘enemy’ and initiates an immune response against it.
Gluten intolerance is also known as ‘non-celiac’ gluten sensitivity.
Celiac disease is an exaggerated form of gluten intolerance. Upon consuming gluten, the immune system attacks the lining of the intestines. the symptoms are more severe, and the recovery is a lot harder.
Here, the body’s immune system, which is meant to protect it, mistakenly acts against it. This is known as an auto-immune response, which can be due to genetic reasons.
Since intestines play a big role in the absorption of essential nutrients, attacks to it over a period of time can result in poor absorption of nutrients, putting you at risk for various deficiencies. Gluten intolerance is non-celiac - the immune responses triggered do not damage the intestines but instead contribute to milder symptoms.
Gluten sensitivity symptoms are not restricted to just the digestive system.
All the fad about gluten-free diets has portrayed gluten-containing products, mainly wheat, in a bad light. While gluten is a big no-no for the gluten-sensitive, reduced consumption of whole-grains may negatively impact your health.
Whole grains like wheat, bran, and rye are rich sources of fiber. They also contain carbohydrates, proteins, and small amounts of B vitamins and minerals.
Thus, avoiding gluten in the absence of an intolerance/sensitivity can end up being detrimental to your health.
Diana Gitig, a Ph. D. graduate from Cornell University, Massachusetts, mentions that celiac disease's first reported case dates back to 100 A.D. It was diagnosed by a Greek doctor, Aretaeus. But the cause of the disease was never understood clearly.
During the Dutch famine in the 1940s, when celiac patients received very less amounts of flour (wheat) for consumption, their symptoms started improving.
When fresh supplies of bread were reintroduced, the symptoms started worsening again. This was when wheat was isolated as the cause of the intestinal symptoms.
Until the 1950s, only 1 out of 8000 were sensitive to gluten. Today, as high as 1 in every 100 individuals are gluten sensitive .
Prof. David Sanders from the University of Sheffield takes help from the concept of evolution to answer this huge rise in cases. He claims that humans started eating wheat only recently, about 10,000 years ago. This is a very brief period considering that humans have walked on the planet for more than 2 million years.
Humans initially consumed raw food, such as plants, fruits, and meat. Processed food (wheat, rye, and other grains), are relatively new in the evolutionary timeline. Prof. David acknowledges this fact and states that our body is still in the process of adapting, especially the food that contains gluten in it. With millions of years of having a gluten-free diet, it makes sense as to why gluten is considered a foreign body by our immune system.
Although a global analysis of gluten intolerance is yet to be done, a nationwide study was conducted in the United States. Over 400,000 biopsy results were examined to understand if ethnicity played a role in gluten intolerance and celiac disease. The following results were concluded after the study :
It is also worth mentioning that gender studies showed that both men and women had equal chances of being gluten-sensitive. Hence it can be inferred that gender does not play a role in this intolerance.
The Human Leukocyte Antigen (HLA) gene system plays a role in the production of the Major Histocompatibility Complex (MHC), which are proteins present on the cell surfaces. They play a role in regulating the immune system.
Two classes of the HLA gene known as HLA-DQ2 (HLA-DQ2.2 and HLA-DQ2.5) and HLA-DQ8 are linked with gluten intolerance risk.
Four types of the HLA gene, HLA DQ, HLA DQ 2.5, HLA DQ 2.2 (has three sub-types), and HLA DQ7, have been linked to gluten intolerance.
In a study conducted to assess the genetic influence on gluten intolerance, nearly all the patients with celiac disease had the risk allele in the HLA DQ2 and the HLA DQ8 genes. The absence of the same was found in 100% of people without celiac disease.In another study conducted to analyze the HLA gene types, people with the C allele in HLA DQ8, T allele in HLA DQ 2.5, the T, C and A alleles in different subtypes of HLA DQ 2.2 (M1, M2, and M3 respectively), and A allele in HLA DQ7 were shown to have an increased risk of reacting to gluten in their diets.
Some of the non-genetic causes of gluten sensitivity are:
Not all people are born with gluten sensitivity. It is possible to acquire it during the course of life. This intolerance can be triggered after surgery, childbirth, or after a period of severe stress.
Gluten sensitivity increases the risk of an adrenal hormone imbalance.
The adrenal glands pick up on the stress levels.
Unstable sugar levels and inflammation of the digestive tract resulting from gluten intolerance cause the adrenal glands to secrete cortisol.
This leads to an increase in body fat, fatigue, and irritable mood.
Fatigue is one of the most common symptoms of celiac disease and non-celiac gluten sensitivity.
In fact, fatigue and tiredness are the symptoms that last longest, even after the individual has shifted to a gluten-free diet.
Fatigue in gluten intolerant individuals occurs due to two main reasons:
Dehydration is also a major cause of fatigue and tiredness in gluten intolerant people.
Patients suffering from celiac and non-celiac forms of gluten intolerance have reported neurological symptoms such as headaches, brain fog, anxiety, depression, and peripheral neuropathy.
Gluten can also cause other disorders like insomnia, migraines, ADHD, epilepsy, schizophrenia, bipolar disorder, and in a minute number of cases, gluten ataxia (antibodies directed at gluten attacks the brain).
Many studies have shown a correlation between gluten intolerance and depression, anxiety, and other neurological syndromes.
A study conducted by Christine Zioudrou and her colleagues at the National Institute of Mental Health in 1979 found that some gluten compounds can attach to the morphine receptors in the brain.
The morphine that is produced in the body is known as endorphins. These are released in our body for various reasons, for instance, to reduce/manage pain.
Certain compounds of gluten (exorphins) mimic the structure of endorphins and attach to the receptors.
Thus, the endorphins have no place to attach to and are not activated. This can lead to mood-related disorders like depression and anxiety.
A large majority of the people who suffer from gluten-intolerance report lack of sleep and poor sleep quality.
Due to digestive symptoms, neurological symptoms, and generalized fatigue and tiredness, most people suffer from a lack of sleep or other related conditions.
[what to do to maintain healthy levels- generally for everyone and specifically for your genotype]
A gluten-free diet seems pretty straightforward - just removing gluten from your diet. But completely avoiding gluten can be challenging as many ingredients added to food like soy sauce, mayonnaise, and roasted nuts also contain gluten.
Whole grains like wheat and barley are well-known harbourers of gluten. So wheat-based bread, pasta, or baked goods should be avoided.
Gluten intolerance or non-celiac gluten sensitivity occurs when the immune system sees gluten as an invader and attacks it. Certain types of the HLA gene family that mediate immune responses in our body play a role in putting an individual at risk of developing gluten intolerance. Gluten sensitivity has also been linked with other health conditions like hormonal imbalance and mental illnesses. Therefore, people who are sensitive to gluten are advised to switch to a gluten-free diet. However, it is important to keep in mind that a gluten-free diet is not everyone’s cup of tea. Most gluten-free products available in the market today are also stripped off of other nutrients and are advantageous only to the gluten-intolerant.
[idea]Osteoporosis affects 200 million women worldwide[/idea]
Osteoporosis is a condition in which the bone mass is lowered, resulting in weak bones that are prone to fractures. This condition is often associated with people over 50 years of age, especially in women post menopause. The propensity for people with osteoporosis to fracture their bones is alarmingly high, with estimates stating that every 3 seconds there is an osteoporotic fracture that occurs across the world.
There are no symptoms associated with the condition until there is a fracture, which is a painful indicator of poor bone health. The brittleness of the bone and the higher chance of fracture forces older people to remain in their homes, worrying about possible falls that could lead to a fracture. This is a significant psychological symptom associated with the condition.
Children with osteoporosis also exhibit poor bone health which not only increases their risk for fractures but could also stunt their growth.
This World Osteoporosis Day 2016, there is a need to explore causes for this condition in order to provide effective solutions. The theme for this year’s World osteoporosis Day 2016 is “Love your bones, Protect your future”
Gluten intolerance is a condition in which the body is unable to metabolize gluten, found in wheat, barley and rye. The condition is caused due to a mutation in the gene HLA DQ and it leads to a range of gastrointestinal symptoms that include nausea, diarrhea, bloating, abdominal cramps and pain. There are certain other extra-intestinal symptoms associated with gluten intolerance that include depression, inability to focus, foggy mind and – possibly osteoporosis. In a gluten intolerant individual, the body is unable to digest the gluten in the diet and this triggers an autoimmune condition where the body’s immune cells attack the lining of the small intestine, where important nutrients like calcium are absorbed. This leads to malabsorption and the resultant lowering of bone density and osteoporosis.
[idea]Gluten intolerance found in 10% of the population[/idea]
Studies have shown that eating a gluten free diet will aid in regaining bone mass, both in children as well as in adults. The tricky part is to identify the condition before it leads to considerable loss in bone density or a fracture.
In a study on school children in Ludhiana, 6 children were identified to have gluten intolerance and none of them showed any other symptom, including gastro intestinal, except stunted growth.
It is difficult to assess intolerance in children based on symptoms as they rarely understand the enormity of the situation and will fail to acknowledge it. The process of eliminating specific food from the diet is also difficult as it can take many months before there is a clear association that is found. Instead gene testing affords a quick and cost-effective solution that detects the mutation in the HLA DQ gene, allowing dietary modification that will limit the risk of osteoporosis.
This World Osteoporosis day, get tested for gluten intolerance and safeguard bone health.
