Food Sensitivity Testing Guide: An Evidence-Based Approach to Identifying and Managing Reactions to Food

Feeling unwell after eating is distressing, and the world of food sensitivity testing is one of the most confusing corners of modern health advice — full of expensive commercial tests that sound scientific but aren't backed by good evidence, alongside genuinely useful medical tests that are.

Food Sensitivity Testing Guide cuts through this confusion. It clearly explains the crucial differences between food allergy, food intolerance, coeliac disease, and the less precisely defined idea of "food sensitivity," then reviews the evidence behind popular tests — including IgG antibody testing, hair analysis, and kinesiology — against current NHS, NICE, and British Dietetic Association guidance.

Rather than promoting another unproven test, this book offers the approach genuinely recommended by UK professional bodies: structured food and symptom diaries, supervised elimination diets, and systematic reintroduction, ideally alongside a registered dietitian. It covers common conditions including lactose intolerance, coeliac disease, histamine intolerance, and IBS/FODMAPs, addresses food sensitivities in children, and includes an important chapter on protecting your relationship with food throughout the process.

Written for UK readers and grounded in current clinical guidance, this is a practical, honest guide for anyone who wants real answers — not just a confident-sounding test result.
