Spring allergies affect a huge percentage of the UK population and airborne pollen is one of the most common causes of seasonal allergies, also known as hay fever or allergic rhinitis. An estimated 80% of your immune system is located in your gut so supporting digestive health is essential to supporting your immune system; this being your primary defense system against all disease, including allergies, sinusitis, rhinitis and asthma.
Processed food, synthetic food additives and genetically modified ingredients all encourage 'leaky gut' (a whole other subject!) and decimate the beneficial bacteria in your gut, having a negative effect on your immune system. Many medicines such as antibiotics also deplete your beneficial bacteria and therefore lower your immune system. Ideally, avoid processed foods and focus on locally-grown (ideally pesticide free) foods and include fermented foods in your diet to optimise your good bacteria, i.e. Sauerkraut, Kefir, Kombucha, Miso or alternatively think of supplementing with a broad spectrum probiotic.

Occasionally people become sick from eating a particular food, because they cannot properly process or digest the food, or because they have a true allergic (immune) reaction to the food. A food allergy and food intolerance (or sensitivity) are sometimes confused with each other, but they are quite different in terms of their origin, symptoms and treatment.
A food allergy can be defined as any adverse, and often immediate reaction to food in which the immune system is involved. In brief, an acute reaction that never reaches the gut. Symptoms include swollen lips, mouth and tongue, urticaria (rash) and vomiting. These will occur very soon after eating an allergenic food. Shellfish, some berries and peanuts, are the common foods that induce an allergic reaction. With an allergy, the immune system mistakes a food for a 'parasite' and goes into overdrive to repel it. Allergies are very specific and affects Immunoglobulin E (IgE). The only reliable tests for allergic reactions are the Prick or RAST (Radio-immunodiffusion Test).
Food intolerance, on the other hand, the symptoms differ in that they often appear many hours, even days after eating the offending food. In the case of an intolerance, partially digested food enters the blood stream and triggers a normal immune system reaction by aggravating the immune system’s mast cells in the gut’s mucous membrane. This reaction is very different to an allergic reaction and tends to lead to long term problems such as anxiety, mouth ulcers, aching joints and muscles, fatigue, headaches/migraine, sinus and mucus problems, digestive disturbances (indigestion, bloating and gas, often all under the umbrella of 'IBS'), hyperactivity and weight gain. The most common food intolerances are wheat gluten and dairy products and stimulants like coffee, sugar and chocolate. Food intolerances are very common and can be reversed. Affects Immunoglobulin G (IgG) and/or other mechanisms such as prostaglandins, leukotrienes, and hence immunity in the gut.
