This week on the Nutshell , Daisy and Clare discuss whether paying more for organic produce pays off in terms of health benefits. There are lots of things to think about from pesticide burden to the nutrient values in the foods themselves. But with ever rising food bills, should you prioritise organic, or can we afford not to?

From fears around hormone disruption, thyroid health, breast cancer, fertility, and even feminising effects in men, soy has been surrounded by controversy for many years.

Yet at the same time, populations consuming soy regularly tend to have lower rates of chronic disease and longer life expectancy. So what does the totality of the scientific evidence actually say?

To answer that question we’re joined by Dr Mark Messina, one of the world’s leading researchers on soya foods and health.

Dr Messina is Director of Nutrition Science and Research at the Soy Nutrition Institute (SNI) Global. He has dedicated his career to studying the health effects of soya foods and has published over 125 articles and book chapters over his three decades of work in the field.

In this deep dive we will distinguish the scientific evidence from pervasive online misconceptions and examine what the current research indicates about soya's effects on cardiovascular health, cancer risk, endocrine function, and well being.

In this week's nugget, Plant-Based Health Professionals' founder, Dr Shireen Kassam takes us through two recently published papers exploring what oncologists may and may not know about diet and cancer, the reasons for this, and what they tell their patients.

This week on the podcast we speak with nutritionist, author, and retired ITU nurse, Karen Lee. Karen shares her journey of following a whole-food plant-based diet to help manage her symptoms of the autoimmune disease, multiple sclerosis. We cover the research showing how whole-food, plant-based dietary patterns may help reduce systemic inflammation, improve gut microbiome diversity, and improve symptoms relevant to many autoimmune diseases.

Clare's vegan omelette recipe:

300g silken tofu

140g firm tofu

3tbsp gram flour

2 tbsp tapioca flour

1/2 tsp turmeric

Good pinch of Kala namak (if available)

Ground pepper

Dash of plant milk if the mixture is a bit stiff

Oil of your choice for frying (optional)

Filling of your choice e.g vegan cheese, mushrooms, spring onions, kimchi!

Blend together the silken tofu, gram flour, tapioca flour, turmeric, Kala namak and pepper. Crumble in the firm tofu and give it a final mix. Heat a small amount of oil in a frying pan. Add the mixture and give the pan a wobble to level it out. Adjust the hob heat so that you can see a bit of steam coming from the pan but it shouldn't be bubbling too vigorously. It will take up to about 20 minutes for the omelette to fully set. When it is starting to look set you can add the filling to the top to start heating through, or melting if it's vegan cheese. Just before serving, fold over the omelette in the pan, then you can slide it onto a plate and decorate with fresh herbs or chopped spring onions.

In this week's nugget, we explore some of the knowns and unknowns when it comes to eating farmed animals who may carry bacteria known to cause disease in humans. The spotlight is on helicobacter pylori, campylobacter jejuni, and e.coli. You might think twice about what you store in the freezer or throw on a barbeque.

This week we are thrilled to be speaking with Dr Michael Klaper, M.D.

Dr Klaper is an experienced physician, educator, and author who has spent decades advocating for a preventive approach to healthcare grounded in healthy, whole-food, plant-based diets.

Through the non-profit organisation Moving Medicine Forward, Dr Klaper’s current work centres on integrating nutrition and lifestyle education into medical training, empowering future doctors to use diet to prevent and reverse chronic diseases, aiming for a more holistic healthcare system.

If you’re interested in the future of medicine, climate and health, preventive healthcare, or medical education reform, this episode offers a powerful and thought-provoking perspective on how clinicians can help build a healthier, more sustainable world.

This week's bonus episode completes our two-parter on psoriasis, as we hear from PBHP member, Kate Dunbar, who prior to the adoption of a whole food plant-based diet was significantly affected by the disease. She has gone on to run marathons, and is the creative master behind many of PBHP's factsheets.Her story is an inspiration to anyone suffering from an autoimmune disease who may have been told diet and lifestyle don't matter. Her experience has even been written up as a case study.

https://pubmed.ncbi.nlm.nih.gov/34366737/

Kate is always very generous with sharing her time and passion regarding the healing powers of food. You can follow her on Instagram @kate.dunbar, find her on Facebook, or email her, kate-dunbar@hotmail.com

We are so excited to be back In The Nutshell as we kick off season six with dual qualified NHS Consultant Dermatologist and nutritionist Dr Thivi Maruthappu.

We cover the inflammatory condition, psoriasis, and find out why it is considered a systemic condition, and how it links to obesity, cardiovascular disease, and metabolic health. Dr Thivi outlines the potential mechanisms through which diet and lifestyle influence systemic inflammation, immune pathways, and the gut microbiome.

We take a closer look at the APPLE study (Asking People with Psoriasis about Lifestyle and Eating), co-led by Dr Thivi and researchers at King’s College London, exploring how overall diet quality relates to psoriasis severity, and how dietary patterns rich in plant-based foods are associated with better outcomes, providing important data that lifestyle and dietary assessments have a key role to play alongside standard clinical care.
