Food Allergy occurs when the body has chemical reaction to eating a particular food & drink. The symptoms for mild to moderate food allergy or intolerance may sometimes be similar, but food intolerance does not involve the immune system and does not cause severe allergic reactions (Anaphylaxis)

A Food Allergy occurs when the immune system reacts to harmless food. Learn to read food labels so you can avoid foods that cause allergic reactions.

Food Allergy & Food Intolerance

Symptoms of food intolerance occasionally resemble those of food allergy so food intolerance is commonly confused with food allergy. Food intolerance does not involve the immune system and does not cause severe allergic reactions (know as anaphylaxis). Food intolerance also does not show on allergy testing. Food intolerance can be a difficult concept to understand and is poorly understood by doctors as well. Sometimes, substances within foods can increase the frequency and severity of migraine, headaches, rashes (such as hives) or stomach upset such as irritable bowel.

Professional diagnosis and confirmation of allergies is important. In Australia, about one in 10 infants, one in 20 children up to 5 years of age, and two in 100 adults have food allergies.

Food Allergies has been Increasing

Allergies in general are on the increase worldwide and food allergies have also become more common, particularly PEANUT ALLERGY in preschool children. About 60 per cent of allergies appear during the first year of life. Cow’s milk allergy is one of the most common in early childhood. Most children grow out of it before they start school.

Inherited Allergy

Children who have one family member with allergy disease (including asthma or eczema) have a 20-40 percent higher risk of developing allergy. If there are two or more family members with allergy disease, the risk increase to 50 to 80 percent.

Most of the time, children with food allergy do not have parents with food allergy. However, if a family has one child with food allergy, their brothers or sisters are at a slightly higher risk of having food allergy themselves, although that risk is still relatively low.

Allergy is an Immune Response

Allergies are an overreaction of the body’s immune system to a protein. These proteins may be from foods, pollens, house dust, animal hair or mould. They are call ALLERGENS. The word allergy means that the immune system has responded to a harmless substance as if it was toxic.

Food Intolerance is a Chemical Reaction

  • Food Intolerance is a chemical reaction that some people have after eating or drinking some foods: It is not an immune response. 
  • Food Intolerance also does not show on allergy testing.
  • Food Intolerance can be a difficult concept for doctors as well. Sometimes substances within foods can increase the frequent severity of migraine headaches, rashes (such as Hives) or stomach upset.
  • Food Intolerance has been associated with Asthma, Chronic Fatigue and Irritable Bowel Syndrome (IBS).
  • Professional diagnosis and confirmation of allergies is important in Australia, about one in 10 infants, or in 20 children up to 5 years of age and two in 100 adults have food allergies.

Therapy

The preferable approach to the nutritional management of immunological food reactions or food hypersensitivities consists of dietary avoidance and the treatment of symptoms resulting  from inadvertent exposure. Nutritional supplements are needed when major food groups are being avoided.  This will ensure the optimum nutritional intakes are maintained. Digestive enzymes example: Dr MH zyame should be taken by individuals who seems to be sensitive to many foods. Bicarbonate of soda , Dr MH Proflora A, taken one hour after meals can improve symptoms. By improving digestion the allergenic load may be destroyed or digested more thoroughly.

Troubled Disc

By Dr. Tan Boon Cheong

Long hours of sitting in front of computer on your desk. Lack of exercise due to busy schedule. Then one fine day, you decided to bend forward to pick up something from the floor or you decided to lift some heavy stuff. As you get up from the position, you suddenly feel an intense pain on your lower back which sometimes radiated down to one or both your lower limbs. This is one of the many scenerios for someone who may experience troubled disc .

Not all this back pain is due to prolapsed intervertebral disc (slip disc). Most of the time, this pain is due to a sudden cramp of the lower back muscles. But if the pain is radiating in nature then the likelihood of slip disc will be higher. Sometimes, this pain may be associated with a numbness on parts of the lower limb. In worse cases, this pain may be accompanied by weakness of the lower limbs, urinary and bowel incontinence.

A consultation with an orthopaedic or spine surgeon is necessary. A good history and clinical examination is good enough to decide if this is a possible disc prolapse. A simple plain X-ray may not be enough to confirm the diagnosis of prolapsed disc. Thus a MRI of the lumbar spine will give a better picture to confirm the diagnosis, the level involve ( usually L4/L5 or L5/S1), the severity of the prolapsed disc and nerve compression.

Not all prolapsed disc need to go under the knife, unless there is neurological deficit as mentioned above. Most of the time, conservative treatment with medication, ice compression, proper resting and physiotherapy or chirotherapy will do the job. Good back care is a must as part of the treatment and also prevention of recurrence. Surgical intervention such as epiduralysis and nerve root injection for pain management or open surgery namely discectomy ( to remove the herniated disc) will be needed if conservative management fail.

ALLERGY & FOOD INTOLERANCE :

It is well known that deficient intake of protein, calories, vitamins, or minerals leads to a variety of nutritional disorders.  It is known that food contaminated with toxic materials or bacteria may cause illness if consumed.  It is also known that certain foods contain non-nutrient poisonous substances that may cause illness and in some cases death.  Nevertheless, it is not generally realised that the nutrient components of foods, in themselves may be toxic for certain people, causing illness or aggravating pre-existing illness.

THEORETICAL CONSIDERATIONS :

Food Intolerance may be defined as any illness or biochemical or metabolic abnormality that is causally connected to the ingestion of any food or dietary component. An illness that is causally connected to non-nutritive dietary component may be referred to as food poisoning or food toxicity. The term food intolerance is usually applied to illness resulting from the ingestion of substances that have nutritive value such as carbohydrate, fat, proteins and amino acids, and accessory factors such as purines (purines are responsible for gout in some sensitive individuals).

There may be an obvious connection between food ingestion and the production of acute illness or a less obvious connection so that a patient may fail to recognise the relationship between his disease and the offending dietary component.

Under special circumstances certain combinations or amounts of food substances may cause illness in otherwise healthy individuals.

For example, fasting followed by refeeding may result in stomach and intestinal distress or fluid retention.  Another example is in illnesses that cause anorexia where feeding may be associated with nausea and vomiting.  This type of Food Intolerance may be considered to be secondary type since the food is non toxic but illness or fasting has so altered the normal physiology that the patient becomes intolerant to many types of food.


REVIEWING SOME COMMON NUTRIENT FOOD INTOLERANCES :

Carbohydrate Induced Food Intolerances

  • Lactose Intolerance is the most common. Most people around the world are deficient in the intestinal enzyme lactase and thus have an inability to digest lactose-containing foods (eg. milk). Symptoms associated with lactase deficiency are bloatedness, wind and diarrhea. Lactose Intolerance may occur of various ages, it may occur at birth or at a latter age to different people. Treatment requires the avoidance of lactose by restricting dietary milk and milk-containing products. Lactose Intolerance should not be confused with milk allergy which is related to milk proteins.
  • High refined carbohydrate diet, in general, may be related to a number of medical problems. For example-low blood sugar (hypoglycaemia) which associated with variety of symptoms including fatigue, weakness, irritability, headaches and sugar craving may classified as diabetic.
  • For the sake of complete example of carbohydrate induced food intolerance are as listed: Glucose-galactose intolerance, sucrose-starch intolerance, sucrose-fruit intolerance, fructose-glycerol intolerance, lactose intolerance, pyruvate dehydrogenase deficiency.
  • All intolerances are due to lack of specific enzymes required for the metabolism of the particular sugar.

Protein Induced Food Intolerance

  • Coeliac disease results from a sensitivity to the protein, gluten, contained in wheat, rye, oats and barley. The disease manifests in most individuals as gastro-intestinal discomfort, wind and diarrhoea. However gastrointestinal symptoms need not be present and the disease may manifest as eczema, or arthritis. Strict avoidance of gluten is necessary in the treatment of this disease.
  • Cow’s milk (casein) allergy or more particular allergy or intolerance to a protein component of milk. It is associated with vomiting, chronic diarrhoea, eczema and failure to thrive.
  • Other common food sensitivities are to egg protein, soy protein and shell fish. Symptoms may vary from hives to gastrointestinal symptoms, asthma to neurological disturbances (poor concentration, irritability, behaviour disturbances). Avoidance of these food results in remission of symptoms.
  • Individuals suffering from liver failure, cirrhosis of liver, kidney failure or pancreatic insufficiency all show intolerance to most proteins. The intolerance is due to the ailing body’s inability to either digest, metabolise or excrete proteins, amino acids or their waste products. So limiting the intake of protein until the body recovers its health or reduce symptoms.

Lipid Or Fat Induced Food Intolerance

  • Symptoms of diarrhoea (Steatorrhoea) wind, fatty motions occurs whenever fat is malabsorbed.  Steatorrhoe represents an intolerance to dietary fat or lipid. Fat malabsorption occurs in pancreatic insufficiency, various disease of the small bowel (cystic fibrosis, coeliac disease, liver disease, gall bladder disease and diabetes. Obviously a restriction of dietary fats or supplementation with digestive enzymes must be incorporated in the treatment of the above diseases.
  • Very high blood fat concentration due to a deficiency in lipoprotein lipase is associated with severe fasting, pronounced elevation in plasma triglyceride, eruptive xanthomas (fatty nodules in the skin) and recurrent episodes of abdominal pain due to pancreatitis. A low fat diet can control the disease process.
  • High blood cholesterol and altered lipoprotein profile can be viewed as a fat intolerant disease. Treatment in most cases requires the introduction of a low fat diet or supplementation with chromium and essential fatty acids.
