About Yvonne

Hello I’m, Yvonne Duffy O' Shaughnessy

Nutrition Therapist and Medical herbalist, as seen on The Today Show, with Maura & Daithi, RSVP Live and RSVP Magazine (where I write a regular Colum)

I specialize in Food Intolerance Testing, Hormone Health and Gut Health through Nutrition, Iridology, Herbal Remedies and everything to do with eating healthy, not dieting! My philosophy is….Don’t Eat Less Just Eat Right.

If you are ready to take charge of your health and make changes to your diet you are in the right place. As a nutritional therapist, my passion is education & information. My goal is to help guide you to improve your nutrition through strategic eating (not dieting) and without expensive supplements, shakes or counting calories because when you know better, you can feel better.

Also specialising in female hormonal balance, I can assist you with fertility, PMT/PMS, pre-conception, PCOS, endometriosis, thyroid, menopause, low energy, low libido, weight loss and more. I apply the latest testing methods to eradicate guesswork and uncover any underlying roadblocks to optimal health. As a wife and mother I understand the daily pressures that women face and the importance of a mind-body approach for women to achieve their full health potential without all the hormonal chaos.

I look forward to working with you soon. Thank you for visiting!

Food Intolerances

How do Food Intolerances Develop?

Food intolerances begin when the digestive system is no longer able to process foods as they pass down the digestive tract. These undigested foods basically go off and putrefy within the intestines. Toxic gut bacteria feed off this undigested food. This creates a toxic gut environment. Bloating, indigestion, acid reflux, constipation, diarrhoea and general gut irritability is the result. Left untreated, these gut toxins begin to seep into the blood stream. There they trigger the immune system into over-response mode (autoimmunity) causing all manner of chronic inflammatory disease. These conditions include Anxiety, Eczema, Fibromyalgia, Arthritis, Gastritis, Asthma, Headaches, Inflammatory Bowel Disease, Insomnia, Irritable Bowel Syndrome (IBS), Skin problems, Chronic Fatigue Syndrome, Constipation, Bloating, Migraines, Sinus, Diarrhoea, Water retention and Weight gain.

Hormone Health

What happens during a Hormone Health consultation?

Your hormones include adrenaline, insulin and cortisol and the thyroid hormones, as well as the sex hormones oestrogen, progesterone and testosterone. Hormones are secreted by various glands around the body including your pituitary, thyroid and adrenal glands, and travel through the bloodstream to reach their target organ.



Did you knew Iridology is Window To Your Health ?

Iridology is the study of the iris – the coloured part of the eye – and how it shows psychological health risks and physiological conditions, challenges and strengths of different organs.

I went to Yvonne approx 6 months ago, overweight, very tired and thinning hair, which I was so worried about. Yvonne did the food allergy test on me and also the Iridology to see what imbalances were in my body. All I can say is this is the best thing I've ever done! I was so tired all the time I did not know where to go next, I had been to my GP and all blood tests were fine! Then I went to Yvonne, She put me on an eating plan, told me what to avoid and what to juice. after 2 weeks I started to feel a bit better, but now 6 months later I feel fantastic. Yvonne helped me out so much and was always there to give me motivation and support. My hair has started to grow again so I am very happy. Thank you Yvonne, your a star! p.s everyone is telling me I look great with the weight gone! Just in time for the wedding!

Sandra Dunne

I had a consultation with Yvonne and was shocked at how much information she could tell me about my health from the Iridology test.
She explained everything to me and has advised me what to do to correct the issues found.
Very informative and easy to talk to, looking forward to seeing an improvement in my health!
Highly recommend

A huge thank you to Yvonne and her team at The Health and Nutrition Coach for helping me through my pregnancy journey.
I first went to Yvonne after I was finding it hard to conceive following a miscarriage. Yvonne put me on her Fertility program, it was daunting at first with a total overhaul of my diet,
regular reflexology sessions and a big bottle of herbs!!!! After a few weeks my energy, mood and weight changed. I couldn't believe it when I realised I was pregnant before the end of the 8 week program. I truly believe that the balancing of my hormones through Yvonne's program made this happen.
So with a heart and a half I thank you Yvonne for all your help, support and friendship throughout my journey". From Tanya, and little Miss Henri xxxxx
