Food Sensitivity Testing Vancouver

This may surprise you, but eight common foods – milk, eggs, peanuts, tree nuts, fish, soy, wheat and shellfish – cause 90 percent of all food allergies. Chances are, half of those items make common appearances in your daily diet. They could, however, be elevating up your cortisol, decreasing your immune strength, and keeping you from achieving your wellness (and weight loss!) goals.

Allergies versus Food Sensitivities

While the cause of true food allergies – the kind that produce severe or anaphylactic reactions — involve IgE antibodies in the immune system, food intolerances or sensitivities can arise when we consume the same foods day after day with little variety. This dietary stagnation causes the body to become “sensitized” to the food. In common parlance, the terms “allergy,” “sensitivity” and “food intolerance” are often used interchangeably, but sensitivities and intolerances are not true IgE allergies.

Food sensitivities or intolerances usually involve a different set of immune system antibodies called IgG antibodies. Symptoms are less intense and typically do not appear immediately, but rather within 12–72 hours, after eating the offending foodstuff. Heartburn, headaches, difficulty getting out of bed in the morning, looking tired even after sufficient sleep, an inability to lose weight, bloating and relentless water retention can all be related to food sensitivities or intolerances.

Because the connection between the symptom and a specific food can be difficult to pinpoint, those who suffer these discomforts often go on feeling worse and worse as their immune system takes a constant beating.

Many of us with food sensitivities don’t even realize how bad we feel until the problematic foods are removed from our diet. Then suddenly getting out of bed becomes easier, our energy, mood and concentration improve and joint pain, headaches and sinus congestion disappear. Here’s a handy chart on common symptoms associated with food sensitivities. You may be nodding your head to more than a few of these side effects:
