After the completion of a health questionnaire (bring your reading glasses if you need them) and a series of health related questions, the test is conducted. The testing method is simple. You hold a small brass cylinder in one hand and a probe (looks like a pen) is placed on a point on you finger and your reactions to over one hundred foods and drinks are measured and your vitamin and mineral status is also recorded.
At the end of the screening your results will be explained to you, you will be given a personalised recommendation plan of action regarding dietary changes and supplement intakes and you will be given colour printouts of your results to take home. In most cases you are advised to return for a follow –up screening to assess your improvements six weeks later.
If you are pregnant or have a pace maker fitted you will not be able to take the test. The test is useful for children over 5 years. Generally under 5’s cannot take the test as they find it difficult to keep still long enough.
Food intolerance is usually difficult to detect, often involving common foods, and is an important factor in ill health. Unlike food allergy, where reaction to food can happen within minutes, food intolerances still involve the immune system but generally produce a slow response to the problem food. The symptoms may appear several hours after eating or at any point up to 48 hours after consumption. Because the food (or foods) in question is being eaten so frequently, often there is no obvious link between the food and the symptoms.
Food intolerance is thought to be a result of a failure of normal absorption. The ‘culprit’ food can aggravate the mast cells in the gut’s lining, causing the gut to leak. Particles of partially digested food then get into the blood stream, causing the immune system to react, giving rise to symptoms such as fatigue, weight gain, arthritis, headaches, skin problems, IBS, asthma and many others. By avoiding all the foods you are intolerant to at once the immune system has a chance to recuperate and actually forgets what you were intolerant to. Most of the foods can then be re-introduced without ill-effects.
BEST stands for bio-energetic stress testing and it is a computerised electro- dermal screening device. The probe (looks like a pen) is pressed onto an acupuncture point, gives off a small electronic signal and this consists of the electro-magnetic signature of the item being tested (every substance, food and vitamin and mineral emits its own electro-magnetic (EM) signal and this is encoded into the system). The reading from the point on the finger changes if the item is causing a reaction and a galvanometer attached to the probe records the reaction and display the results on the computer screen. The results are measured on a scale of 100. Acceptable foods (those to which the patient is not intolerant) will score between 48 and 55. Foods which are lower indicate intolerance.
