A food intolerance is not the same as a food allergy.

A food intolerance occurs when you have difficulty digesting a particular food, leading to gastrointestinal symptoms such as abdominal pain, intestinal gas, diarrhea, and bloating. A food allergy, on the other hand, can be defined as an adverse immunologic response to a dietary protein.

Food allergies are more fatal in nature and can severely impact your health, whereas food intolerances are less severe in nature and mostly confined to digestive problems. Reactions to certain foods are fairly common, mostly caused by food intolerances rather than food allergies.

Say, if you’re lactose intolerant (lactase deficiency in the small intestine), you may still be able to drink lactose-free milk or consume lactose enzyme supplements in order to aid your digestion.

Still, these borderline rules can’t be generalised in the context of how human genealogy has evolved over the years, and how, based on that, the DNA-based treatment protocols and dietary recommendations have so far influenced the scientific outlook for the betterment of your informed health decisions.

How food intolerance impacts your weight loss goals

Speaking of weight loss, food intolerances can cause excessive gas production in the gastrointestinal tract, can slow down your metabolic rate and can directly impact your weight loss goals.

Food intolerances can also cause inflammation and weight gain due to cortisol constantly stimulating high levels of insulin, which keeps the body in fat storage mode.

The reason linking food intolerance to weight gain is that chronic inflammation caused by the immune system can impair your brain’s ability to receive appetite suppression messages from leptins, preventing you from feeling full, and as a result, you overeat!

Delayed food intolerance (caused by IgG antibodies, also called type 3 allergies) can cause chronic inflammatory responses in the body. Food intolerance caused by IgG antibodies can lead to low grade inflammation in obese people, preventing weight loss.

Causes and symptoms of food intolerances

Now, let’s see some of the probable causes of food intolerances in individuals as follows:

  • Celiac disease (gluten intolerance): Celiac disease is an autoimmune disorder triggered as a result of eating gluten, which is essentially a protein found in wheat, barley, rye and other grains
  • Irritable bowel syndrome ( Coffee, carbonated drinks, processed foods and alcohol related): Irritable bowel syndrome is a condition that affects the digestive system (the large intestine). It can cause abdominal cramps, bloating, diarrhoea, constipation and a change in bowel habits.
  • Enzyme deficiencies (Mostly lactose intolerance related): Enzymes are essential for digestion and for the proper functioning of the liver. Enzyme deficiencies are inherited defects, which result in an inability to produce primary bile acids. Most people with inherited metabolic disorders have a defective gene that results in an enzyme deficiency. Lactose intolerance is a classic example.

Some of the common symptoms of food intolerance are:

  • Abdominal pain
  • Headaches
  • Runny nose
  • Diarrhea
  • Rashes
  • Fatigue
  • Bloating
  • Nausea
  • Anemia
  • Joint pain

Why are DNA-based diagnosis and DNA-based dietary recommendations good for you

Food intolerances can be difficult to diagnose, their causes difficult to narrow down, and as a consequence, difficulty to treat. Food intolerances can be partially diagnosed by elimination diets, but without the scope of finding more optimal and lasting solutions.

While a clinical diagnosis might greatly help in the elimination of all that cause the food intolerances in you, you must remember that they don’t always point in the right direction.

Your own genetic factors contributing to your food intolerances can be clinically tested, mapped, thoroughly studied and dietary recommendations prescribed, according to what your genetic predisposition predicates and what your genetic markers point to.

Your prescription to optimal health and healthy lifestyle can very well be found in DNA-based approaches and DNA-based dietary recommendations, given the fact that these hands-on solutions backed by vast research and clinical data are more to sure to help you than the off-the-shelf dietary recommendations.
