Читать книгу The Food Intolerance Bible: A nutritionist's plan to beat food cravings, fatigue, mood swings, bloating, headaches and IBS - Antoinette Savill, Antoinette Savill - Страница 8

As mentioned, food intolerance is the name for reactions mediated by immunoglobulin G (IgG). These reactions can manifest up to 72 hours after exposure, making the trigger food or substance much more difficult to identify. However, it is worth noting that some food intolerance reactions are not typically mediated by immune reactivity.

While people who suffer from IgG reactions rarely need immediate medical attention, the symptoms can certainly reduce their quality of life and cause longterm illness. The proportion of the population who suffer from at least one food intolerance is as much as 45 per cent (and that may be a conservative estimate), making it a significant issue in the nation’s health.

Evidence shows that the prevalence of food intolerance is escalating, but because the methodology used to analyse food intolerance is more recent than that for IgE allergy, there are no hard-and-fast figures to compare with the prevalence of decades ago.
