Food Intolerance Treatment
Personalised food intolerance nutrition therapy that targets chronic bloating, abdominal pain, constipation cycles and unpredictable food‑triggered digestive reactivity.
Food Intolerance Subtypes
Clinical nutrition therapy for enzyme‑related, immune‑mediated and dose‑dependent food intolerances with tailored strategies.
Nutrition Therapy
Expert‑guided food intolerance nutrition therapy that identifies the real drivers of your symptoms. Evidence‑based protocols that improve tolerance, and support long‑term digestive stability.
Food Trigger Identification
Systematic identification of food intolerance triggers including FODMAPs, additives, and dose‑related reactions. A structured approach that clarifies what your gut can tolerate and expands over time.
Chronic Intolerance Patterns
Support for long‑standing food intolerance patterns with persistent bloating, pain and bowel irregularity. Personalised nutrition therapy that restores digestive rhythm and improves daily quality of life.
Symptom Mapping
Comprehensive assessment to map your food intolerance symptoms and uncover the patterns driving flare cycles. Targeted nutrition therapy that builds stability and supports long‑term digestive regulation.
The gut microbiome influences immune function, mental health, hormonal regulation, weight management, skin health and energy, yet food intolerances often leave people managing symptoms for years rather than resolving the underlying cause.
Jake’s clinical approach starts with a thorough intake including current symptoms, health history, recent investigations, diet and lifestyle and builds a plan specific to your food intolerances, not a generic protocol pulled from the internet.
Whether you are newly reactive, have tried everything or simply know something is off, this is the level of food intolerance care that actually moves the needle.
70%

15%

95%
Serotonin is produced in the gut, the gut-brain axis directly shapes mood and cognition
Chronic bloating
Daily bloating that does not resolve with dietary changes signals increased intestinal permeability.
Abdominal pain
Recurrent pain or cramping that disrupts meals, sleep or daily function indicates active leaky gut patterns.
Constipation cycles
Slow, incomplete or infrequent bowel movements that cycle unpredictably reflect impaired gut motility.
Explosive diarrhoea
Sudden, urgent or watery stools point to gut lining irritation, increased intestinal permeability.
Post‑meal discomfort
Pain within minutes of eating suggests irritation of the gut lining and heightened sensitivity associated with active leaky gut.
Food intolerance expansion
A growing list of foods causing symptoms indicates worsening gut barrier permeability.
Unpredictable flare cycles
Symptoms that spike without clear triggers show unstable gut regulation driven by gut lining irritation.
Self-management failure
When supplements, diet changes or online protocols fail, it reflects deeper gut‑lining dysfunction.

No, you do not need a formal food intolerance diagnosis to book. Many clients come in with bloating, abdominal discomfort, irregular bowel habits or unresolved digestive symptoms without a clear label. Jake will conduct a thorough intake, review any existing investigations and may recommend further testing where appropriate. A diagnosis helps, but it is not required to get started.
A gastroenterologist manages the medical and diagnostic aspects of gut health, while Jake builds a personalised nutrition strategy that restores gut function, reduces inflammation and stabilises daily food intolerance symptoms.
They work differently, and many clients choose to work with both for the most complete care.
No, you will not be placed on a highly restricted diet.
Jake’s approach is structured, personalised and clinically guided, but it is designed to be sustainable and flexible.
The goal is to support gut function, calm inflammation and stabilise food intolerance symptoms while keeping your diet as broad and enjoyable as possible.
Most clients actually gain more dietary freedom over time, not less.
Most clients begin noticing meaningful changes within the first few weeks.
Improvements often include better energy, more stable digestion, reduced bloating and clearer structure around what their gut needs.
Gut healing itself evolves over time, but the behaviours that support gut‑lining repair, calm inflammation and relieve leaky gut symptoms begin shifting almost immediately.
Jake monitors your progress closely and adjusts your plan so you continue moving forward with confidence.
Yes, Jake can work alongside your GP or Gastroenterologist.
A GP provides broad medical oversight and a Gastroenterologist manages diagnostic, structural and medical aspects of gut health, while Jake focuses on the nutritional, metabolic and behavioural drivers that influence your digestive symptoms.
Jake combines world class expertise as a food intolerance nutritionist with extensive experience supporting both younger clients with emerging food trigger symptoms and adults already managing chronic food intolerance patterns. His approach gives clients a clear clinical advantage built on precision, science and measurable results.
