Medical Conditions

Rachel can help assess, diagnose and treat your dietary or medical condition.


Low iron status can result in anaemia, which can lead you to feeling constantly tired and fatigued. Iron is an essential mineral that cannot be made by the body and therefore, it needs to be consumed in the diet. This can be challenging for some people, especially those who follow a plant-based diet or those who have variations in genes responsible for iron metabolism. 

Rachel can help you identify any genetic variations that could be putting you at risk of anaemia and improve your iron status through dietary modification which will naturally enhance your energy levels. 

The TMPRSS6, TFR2 and TF genes code for proteins involved in iron metabolism – 2 in 5 people are at risk of low iron status due to issues in transporting iron around the body. 

Bone Health

Prevention and treatment of Osteopenia and Osteoporosis is primarily diet-based and certain people may be more at risk than others. For example if you are vegan, a woman over 50 or possess a genetic variation that can put you at risk of low calcium or vitamin D deficiency. 

Prevention of weak bones is important to minimise breakages and problems with mobility in the future. Rachel will guide you through easy lifestyle changes to counteract genetic predisposition you may have and achieve optimal bone health.

People who possess certain variants of the GC and CYP2R1 genes are at higher risk of low Vitamin D and calcium status, which can potentially increase risk of Osteopenia and Osteoporosis. 


Diet is considered first line treatment for the prevention and management of Type 2 diabetes. 

Your DNA, specifically the TCF7L2 gene, can help further personalise your dietary advice for your genetic makeup – 1 in 2 people possess certain variations of this gene, which increases their risk of type 2 diabetes  which is counteracted if whole grain consumption is high. 

As a Registered Dietitian, Rachel can educate you and formulate dietary advice to ensure the food you eat will manage or even reverse your type 2 diabetes.


Digestive Issues

Food Intolerances

Digestive and health issues caused by food intolerances and sensitivities can be investigated using scientifically sound elimination and reintroduction methods as well as Nutrigenomic testing for example identifying your variant of the MCM6 gene for risk of dairy intolerance, HLA gene for risk of gluten intolerance and ADORA2A for caffeine sensitivity. 

Rachel can identify the exact foods that are triggering your issues to formulate dietary advice to keep uncomfortable symptoms at bay. 

Eliminating some foods from the diet without seeing a Registered Dietitian can cause deficiencies or other complications. Rachel uses a careful and holistic approach; these complications are well monitored and controlled. 

Coeliac Disease

Gluten is a harmless protein found in many foods however some people have a condition where gluten is damaging to their gut lining, causing nutrient deficiencies and consequential health conditions in the future.

If you have unpleasant digestive symptoms, Rachel can assist in the diagnosis and treatment of Coeliac Disease with in combination with your Doctor. Your care is best managed by a Registered Dietitian to ensure an exclusively gluten free diet that is balanced and meets all other nutrient requirements essential to health.

Are you suffering with unpleasant loose bowel movements? Diarrhoea naturally impacts on your daily life and can cause unnecessary stress for you. Rachel has completed further training in this area of digestive health and can help you with lifestyle and dietary modifications to help manage this burdening area of your life.

Diverticular Disease

Diverticular disease and diverticulitis are common digestive conditions that affect the large bowel. Dietary management is part of both prevention and treatment.

Rachel uses a dietary intervention to reduce inflammation and maintain remission, preventing unpleasant symptoms associated with the disease.

Heart Disease

High Cholesterol

Also known as Hyperlipidemia, high cholesterol is best managed through lifestyle and dietary interventions.

Rachel uses the most up-to-date scientific research to understand how you process saturated fat to support the reduction of ‘bad’ LDL cholesterol (using the APOA2 gene) and work out how best to increase ‘good’ HDL cholesterol‘ using the FADS1 gene.

This approach ensures the most effective diet and lifestyle advice to prevent heart disease and even supporting cardiac rehab.

High Blood Pressure

Also known as Hypertension, high blood pressure is a risk factor for heart disease and can lead to heart attacks and strokes in the future. What you eat plays a huge role and Rachel can assist in dietary modification to reduce your blood pressure and help reduce your risk of heart disease.

Personalised dietary advice for your individual requirements are crucial here for caffeine and salt…

The ACE gene is involved in blood pressure regulation in the body and variants in this gene can put you at risk of being more sodium sensitive, which increases your risk of higher blood pressure. 

Variants in the CYP1A2 gene means 50% of the population are doubling their risk of high blood pressure and a heart attack drinking more than 2 cups of coffee per day. The other 50% require more to protect their hearts!

Cardiac Rehab

If you have previously suffered a heart attack or stroke you are at higher risk of having another. Rachel can help you with dietary modification to help reduce your risk of another life threatening event using robust science and your DNA insights.
