I ordered a gut health microbiome test through Nutrition Diets. They analysed my test and have helped treat my digestive symptoms with personalised nutrition and lifestyle medicine. I'm really happy with the results and feeling great again. Would definitely recommend for anyone looking to improve their gut health!

What a wonderful, kind and caring woman Carmen is! So after going back and forth to many NHS doctors with them basically telling me I had IBS and I would just have to manage. I was broken inside with terrible gut issues every single day and was honestly so confused and scared as I had no idea what was happening to me or where to begin to get rid of it. But then I started to go out of my way to find a different kind of help as I knew I could get better from this, and then I found the lovely Carmen and have been working with her since February, we had our first phone call and I already felt a massive weight lifted off my shoulders and after that I knew things were going to be okay and I was going to get better! Over time, with Carmen’s amazing help, I really started to believe I could regain my health back. We ran a stool test which identified pathogenic bacteria overgrowth in my system and even though that sounds awful, it was just a relief to actually get to the bottom of what was going wrong with me in order to fix it. Carmen has helped me get over my awful anxiety about this all with her care and knowledge and has really helped me include some amazing foods in my diet with her nutritional advice. Carmen is so patient, real and genuine and I’m over the moon to have found her, what an angel! I’m still on my gut healing journey, but I don’t know where I’d be without Carmen! I have come so far in such a short space of time, I have got my life back and that’s all thanks to Carmen helping me!

Working with a functional medicine nutritionist has really helped me understand where I was going wrong with my diet and taught me how to make better food and lifestyle choices. Huge thanks to Carmen and Nutrition Diets for all their support and getting me back on track.

I have been having telephone consultations with Carmen now for just over 1 year now. If I never found Carmen I don’t think I would be where I am now, which in my opinion is very good as you can never get appointments with your own doctor, especially being diagnosed with Mcas (mast cell activation syndrome). Carmen is very knowledgeable and a lovely functional medicine nutritionist who as helped me to overcome my illness, which is very complexed. She does Skype also so you are actually getting a face to face appointment. Carmen puts her patients first always and is very understanding, I would recommend Carmen 100% as she is very passionate in what she does, and she will do her best to help you in anyway. So I would like to say Carmen a BIG Thank you for helping me get to where I am today, if it wasn’t, for you I just don’t think I could of managed this illness on my own. You are one amazing women.

After assessing my diet and taking a gut microbiome test, Carmen designed a personalised health plan to restore my gut health. Her ongoing support and expertise have been invaluable and following her advice my symptoms have finally gone. Fantastic service. Highly recommend trying Nutrition Diets.

Carmen has been fantastic. She's really helped me understand what I eat by keeping a long-term food diary. You can clearly see trends and how stress affects the gut, which then affects everything else. She is knowledgable, loving but also very candid when she needs to be, which is exactly what you want from a professional who is trying to help you. Brilliant service, highly recommend.

Nothing but good things to say about Nutrition Diets who have been supporting me with skin issues and mild hair loss.
The whole process has been online which has been really convenient and I can't emphasise enough how reassuring it's been to finally understand the causes of what's been bothering me in a way that my own doctor wasn't able to provide.
Carmen recommended the DUTCH test which I took at home. That was easy and once the lab processed the test, she analysed the results and designed a treatment plan aimed at supporting my hormonal health which involves a combination of diet, lifestyle changes and supplements.
I've now had 3 sessions with Carmen since starting 3 months ago and I can already see a big improvement. 5 stars!

Thanks to functional testing and nutritional therapy I've finally been able to understand what has been causing my stomach issues and do something about it. After my initial chat with Carmen I felt confident I was in good hands as she specialises in gut health. I followed her advice and took a stool test in which she identified SIBO in my system.
Since then I've been following the diet and lifestyle plan she made to target my condition and the results have been brilliant. After two months, my symptoms have already improved significantly. I now know what foods to avoid, and what my triggers are. The whole process has been online/from home and has been really simple. I would not hesitate to recommend anyone with digestive issues.

I visited Carmen about 6 months ago for my eczema as I was struggling with severe dry, red, inflamed skin.
During those 6 months Carmen explained the potential root cause of my problem and suggested to run some functional tests. I did a stool test followed by a food sensitivity test as I noticed that I was reacting to certain foods with my skin getting worse again.
The results from stool tests showed that I was low in an immune marker making me more sensitive to infections as well as low in digestive enzyme hence I was not absorbing my food well. This finding was reflected also on my blood test results. Besides, the stool test showed low in commensal bacteria which Carmen explained is a typical scenario seen in patients with eczema. The low diversity of my gut bacteria was contributing to high inflammation and consequently my skin was not healing.
Besides the functional testing, she requested a blood test through my GP. We analysed my blood results and went through everything that was low. Carmen likes to work with food first so I introduced foods rich in vitamins and minerals and more fibre as these lacking in my diet followed by specific supplements to bring those deficiencies back to a normal level and speed up the healing process.
I changed my diet and lifestyle accordingly after the tests results with Carmen’s support. I stopped eating what ever my body was not accepting such as sugar, fast foods and especially gluten.
My skin was on and off to start with. Some days would be better and some days would be bad but I had a strong feeling my gut was healing slowly but surely so I persevered. With time, I started to sleep better and for longer hours, waking up energetic but most importantly my skin would always be clear !
Now 6 months later with hard work, I can finally sleep at nighttime without scratching, I can also see my skin is not longer inflamed. I could not have done this without the help and support of Carmen. All my love to her and what she does for her patients, I cannot recommend her enough ! 🌸💙💜🌸💙💜

I am so grateful and thankful to Carmen for being there and keeping me healthy. My nutritionist for 4 years, guiding me through and out the other side of tricky health issues. She came highly recommended to me in 2019 when I was diagnosed with a hiatus hernia and acid reflux (following years of gastritis flare ups). Carmen has also been helping me with hormonal imbalances and inflamation in the body (through diet, superb supplements, liver detox programme and gut analysis). She has helped me through difficult times again recently when I had to undergo hospital operations, and of course it was Carmen who I reached for afterwards. I feel safe in the knowledge that she sees and looks at the whole picture, and I have been able to heal my body with her support, guidance and knowledge. I continue to see Carmen and cannot recommend her highly enough.
Having consulted with many doctors over the years regarding my digestive issues, they all seemed to contradict each other and/or ultimately not help or get to the root cause of the problem. After finding Carmen she instantly stood out as being the most interested and caring person I have yet consulted with. She knew much more about digestive issues than any doctor or gastroenterologist I have yet come across and gave me great information on how I could cure my issues getting to the root cause. I would highly recommend her to anyone wanting to heal their gut or who has suffered with digestive distress. Passion and commitment is clearly something Carmen has and it is shows through her work. 10/10
I enjoyed my session with Carmen as my dietitian a lot and really appreciate the knowledge she has and the help she gave me to look at things in a healthy way. She also made me realise that mils don't need to be complicated and difficult, it really can be fast and easy. Thanks so much for your help 🙏 Carmen.
A couple of years ago I caught what I thought was a typical cold but when the symptoms persisted for over a month I went to see a doctor who prescribed me antibiotics. A few days later I became so ill I was admitted into hospital where I was diagnosed with a very rare and serious neurological autoimmune condition known as ADEM.
As part of my rehabilitation, I researched various forms of therapy and asked my consultant to refer me to a nutritionist. Carmen’s knowledge and guidance has taught me what the right foods are for increased cognitive functioning and she has designed a special supplement plan for my brain and nervous system to support my ongoing recovery.

After 9 months of seeing Carmen I am witnessing an amazing improvement on my exzema prone skin.
I first met Carmen several years ago when I visited a clinic of Natural Therapies, her gentle and supportive manner was always in my memory, so I was so pleased to see her name come up when looking for some nutritional advice. I am perimenopausal and have always had problematic skin. After my initial consultation, Carmen devised a realistic plan to follow and little by little dietary adjustments and supplements to support my immune system have pretty much cleared my skin, also my general health and energy levels have increased and I realise my body hasn't felt this good for a very long time. Her support throughout has been fantastic, her knowledge is admirable and I feel so fortunate to be guided by her.

Carmen went through my microbiomes tests and helped me understand what I needed to do to improve my gut health.
She's also a very friendly and nice person to speak with.
Carmen has been my nutritional therapist for over a year now. Our first interaction was after fibroid surgery. Since then Carmen and I have been working very closely to improve my overall health and now on my fertility journey. What I love about working with Carmen, is that she treats me as the invidual that I am. She helps me to find the right solutions based on my lifestyle and my budget. After years of seeking this kind to f approach, I'm really glad to have found Carmen. I wouldn't trust anyone else.
Working with Carmen has been the best decision of my life.
If you are looking to feel energised, be healthier feel healthier and don’t just want to treat the symptoms but also the root cause I highly recommend Carmen, she completely changed my understanding and relationship with the foods I eat.
Carmen takes the time to get to know you, your diet, she analysed and assessed all the information and came up with a plan that works for me.
Thanks to her I was able to identify that part of my health issues was the fact I am allergic to gluten etc.
I was also suffering with the effects of an under active thyroid such as cold feet and hands, very low mood and oh god the bloating lol.
Her vibrancy at all times is always a plus and she never makes you feel like you’re the problem or whatever the condition Carmen is very knowledgeable I’ve learnt so much from speaking with her.
If you are looking for a practitioner that inspires change, not only knows what they are talking about but is very passionate about it then Carmen is the who you’re looking for!!
Thanks to your help and advice regarding changes to my life style, diet and supplements, I feel better. When I first spoke to you I was having difficulty with my sleep, weight, and hormones, and feeling very low. Your advice and the changes you suggested I found to be very beneficial, both physically and mentally. Furthermore, having followed your advice and taken up some form of exercise, I have found since I started swimming that my sleep has improved, I feel more energised, and my weight is now under control. I would like to come back to you for a review in the next few months. Thank you for helping and encouraging me.
I first started seeing Carmen over 7 years ago. She is professional, knowledgeable, friendly and always very supportive. Carmen was able to convince my then teenage daughter to improve her diet and her health and continues to treat her from time to time. Carmen has always offered practical advice, useful explanations and nourishing food tips. Under her guidance I recently completed a 14-day detox, a great cleanser which I probably would not have completed without her continued support and encouragement. Highly recommended.
The clean liver detox programme that Carmen recommended to me is a commitment but the benefits are worth it. The supplements and shake detoxify your system and liver pathways and it’s good knowing that you are doing something positive for your body and total health. I last did it in Feb/ March 2021 as I was feeling in need of a cleanse after a year of being at home and too much sugar, I felt that my system was sluggish and needed to be refreshed. I’ve done the detox around 3-4 times now at different points in the past and always enjoy it.
My advice would be to do it when you know you can be calm and enjoy it, not when you have deadlines at work and lots happening. Following the programme whilst working from home is easier but I have done it when commuting to an office also. Spend a good few days reading through everything and buying the relevant food shopping so that you are prepared to start. There are some delicious meals on the menu and you don’t need to restrict yourself to quantities. 14 days does seem like a long time but it’s separated into three sections which makes it more manageable. The first time I did the detox I had a headache for the first few days which is a sign that my body was getting rid of unwanted toxins but subsequently haven’t. My skin was glowing and my eyes were brighter. I definitely felt better avoiding all the inflammatory foods and stimulants. Carmen always makes herself available if you have any questions or issues.
I highly recommend it.
