Nutritional Therapy

What Is Nutritional Therapy?  


Nutritional Therapy is an evidence-based approach to maximising one’s health potential though individually formulated nutritional and lifestyle changes.

It promotes the benefits of good, wholesome, unprocessed foods for optimal well being, as well as the therapeutic effects of particular foods for specific health conditions.

Nutritional Therapy treats the body as a whole while seeking the root source of health concerns, rather than simply treating the symptoms.

It works on the basis that we are each individual in our make-up and therefore, ‘one size fits all’ models of eating (often based on outdated research) simply don’t work well for a lot of people.

What is a Nutritional Therapist?

A qualified Nutritional Therapist is someone who holds a 3 year diploma in Nutritional Therapy and is trained in basic biochemistry, physiology and pathology as well as supervised clinical practice. As such, a Nutritional Therapist is qualified to work in private practice and see clients on a one to one or group basis.
A Nutritional Therapist offers personalised diet & lifestyle advice which is tailored to your individual health needs and goals. This includes carefully chosen dietary recommendations, practical meal suggestions and recipes as well as tips on how to incorporate the changes into your lifestyle.

How can Nutritional Therapy benefit me?

Nutritional Therapy is suitable for everyone, young and old, for those who would like to alleviate specific symptoms, as well as those who would just like to improve their overall health and wellbeing. In a nutshell, Nutritional Therapy helps you to identify the foods that make you look and feel your best.

What health concerns will benefit from Nutritional Therapy?

 Digestive Problems (Constipation, Diarrhoea, bloating, IBS, Reflux, Food allergies/Intolerances, diverticulitis)
• Weight problems (Weight gain/inability to lose weight, sugar cravings, blood sugar imbalances, diabetes)
• Cardio-Vascular Health (Raised cholesterol, high blood pressure, Metabolic Syndrome)
 Hormonal Imbalances/Women’s Health (infertility, PMS, PCOS, Endometriosis, Menopause symptoms, Recurring Thrush, Cystitis.)
• Skin Conditions (Acne, Eczema, Psoriasis, Rosacea)
• Mental health & General Wellbeing (Low mood, Anxiety, Fatigue, Poor Concentration)
• Autoimmune conditions ( such as Fibromyalgia, Chronic fatigue syndrome, Lupus, Rheumatoid arthritis, that often do not respond to conventional medicine)

What kind of diet & lifestyle advice can I expect to receive from a Nutritional Therapist?

As part of the consultation process, a nutritional therapist will go through the client’s medical history and assess current health status. The clients personal health symptoms, needs and goals will be discussed and a personalised nutrition plan will be devised on this basis.

Nutritional Therapy focuses on natural unprocessed whole foods which heal the body and boost overall health. A Nutritional Therapist will work with the client to devise a meal plan that is nutritionally balanced, practical, enjoyable and sustainable. If any foods need to be reduced or eliminated for a period of time, viable alternatives will be suggested that will maintain nutritional needs.

Where necessary, a Nutritional Therapist may also prescribe natural supplements in safe doses e.g. probiotics, vitamins & minerals to help alleviate certain symptoms or optimise nutritional status. However, natural foods are always the first line of treatment.

Nutritional Therapy is not intended to replace conventional medicines but to complement them, and, where necessary, dietary changes can be made under the supervision of a Medical Doctor.

Oonagh Peters 

Naturopathic Nutritional Therapist & Wellness Consultant
Dip. Nut. CNM, mBANT, mNTOI, mANP.

I am a registered and qualified nutritional therapist, and wellness consultant.   I have a diploma in Naturopathic Nutritional Therapy from The College of Naturopathic Medicine in London. I am a member of ‘Nutritional Therapists of Ireland’, ‘British Association of Applied Nutrition and Nutritional Therapy’ and ‘Association of Naturopathic Practitioners’.

I focus my work in the fascinating area of women’s health and have a special interest in menstrual conditions, optimising fertility naturally, IVF support and pre-conception care.

I recognise that many women suffer needlessly with health conditions that are not always externally visible. We often just “get on with it”. There is so much that can be improved with good nutritional support and lifestyle improvements.

I have successfully helped clients with PCOS, endometriosis, PMS, heavy / painful / irregular periods, thyroid conditions, low libido, acne, rheumatoid arthritis, hashimotos, psoriasis, digestive issues, IBS, reflux, perimenopause / menopause symptoms, weight gain, weight loss, type 2 diabetes, blood sugar dysregulation, high blood pressure, high cholesterol, mood changes, emotional eating, depression, anxiety, chronic fatigue, recurrent infections, gut conditions (infections, food poisoning, parasites, candida), low energy and more…

To me, being ‘healthy’, means being happy and having the energy and confidence to enjoy your life.

We are all biochemically individual and there is not a “One Size Fits All” prescription when it comes to finding true health.

I work with clients to find the root cause(s) to their health complications. Identifying the triggers and drivers, and then working closely with them to improve over time, to re-establish health and vitality. My approach is very personal and supportive. During the consultations, we discuss everything from birth up to the current day, as well gathering details about your family history and their health.

A typical plan includes:

Foods to increase, food swaps, handouts / fact sheets, shopping advice, tips for reading labels, meal preparation tips and recipes, meal ideas, exercise suggestions, relaxation techniques, sleep advice, environmental tips, resources: books / websites / videos, tests to request from your doctor e.g. blood tests, items to discuss with your doctor, private test recommendations e.g. hormone, genetics, nutrient profile, supplements.

Before becoming a Nutritional Therapist, I worked in IT Services for 15 years. For the majority of my career, I worked as a Service Manager for a team of IT customer service agents. That role enabled me to become skilled many areas that are relevant to me today; goal setting, working with different personalities, finding solutions to challenging circumstances, understanding stressors, understanding corporate demands, being supportive and conducting productive one-to-one meetings.

I strongly believe in evidence based nutritional therapy.  As part of my Continuing Professional Development, I regularly participate in webinars, attend conferences and seminars.
