The reality is\u00a0<strong>far from fancy<\/strong>, though.<\/p>\n<p><strong>Hair analysis<\/strong>\u00a0\u2013 a lock of hair is sent to a laboratory and the energy fields in the hair are scanned to \u2018determine\u2019 food intolerances. The companies claim to\u00a0<strong>fix everything<\/strong>\u00a0under the sun and propose that the energy signals can pinpoint what is putting stress on your immune system.<\/p>\n<p>Hair analysis is<strong>\u00a0complete pseudoscience<\/strong>. Therefore, it\u2019s safe to say this method is, quite simply,\u00a0<strong>quackery<\/strong>!<\/p>\n<p><strong>VEGA tests \u2013\u00a0<\/strong>Also known as an electrodermal test, this claims to measure the body\u2019s energy levels. The patient holds an electrode in one hand and the practitioner then uses a probe on the foot or other hand. If a trigger food is detected, there will be a dip in the electromagnetic conductivity.<\/p>\n<p>This method is\u00a0<strong>no better than chance<\/strong>, sorry to say!<\/p>\n<p><strong>Are the answers in your heart?<\/strong><\/p>\n<p><strong>Pulse tests \u2013\u00a0<\/strong>You may have also heard of pulse tests as a method for detecting a food intolerance. The pulse is taken before eating a suspect food and measured 15 minutes after consumption. An increase in heartrate claims to indicate food intolerance. Again, this holds\u00a0<strong>no basis in science<\/strong>\u00a0and there is no correlation between heart rate and food intolerance.<\/p>\n<p><strong>Are the answers in your blood?<\/strong><\/p>\n<p><strong>\u201cLive\u201d blood testing\u00a0<\/strong>\u2013 This is where blood is mixed with the suspected food. It is then monitored to see if the white blood cells \u2018change\u2019 under the microscope. If they do change, this \u2018indicates\u2019 a problem food. This is an\u00a0<strong>unproven method<\/strong>\u00a0and holds no scientific basis.<\/p>\n<p><strong>IgG blood tests<\/strong>\u00a0\u2013 This blood test looks at the IgG antibodies in blood. An increase in the levels of IgG can indicate an intolerance to a specific ingredient. There\u2019s a\u00a0<strong>large, and growing, body of scientific evidenc<\/strong>e that supports giving people choices about what they eat based on the results of a food specific IgG blood test.<\/p>\n<p>The main tests you\u2019ll find online are hair tests and IgG blood tests.
