In a Nutshell: The Plant-Based Health Professionals UK Podcast

Oat milk has enjoyed growing popularity in recent years. Despite a flurry of questions around its healthfulness, this is a plant milk generally accepted for its taste, and which is widely available. It's also often calcium fortified to the same level as dairy. Nevertheless, concerns remain  regarding the swap from cow's milk. Perhaps you've even been persuaded to wear a continuous glucose monitor whilst drinking your latte?
So, for those of you for whom no other plant milk will do, podcast hosts Daisy and Clare explore the good and bad of the nation's most popular plant milk.

In this episode we are joined by Dr. David Jenkins, MD, PhD, DSc, a globally recognised leader in nutrition science, research and metabolic health.

Dr Jenkins is best known for developing both the Portfolio diet and the Gycaemic Index. His work has shaped how we understand the relationship between carbohydrates and blood sugar, lipids and heart health, and continues to influence how clinicians and researchers approach nutrition science.

In this episode we explore the cholesterol-lowering foods which make up the Portfolio diet, a dietary pattern that can have a powerful effect on lowering LDL cholesterol and reducing cardiovascular risk.

We break down the science behind the diet, how it works in real life, and why it’s gaining attention as a practical dietary strategy for improving heart health.

This week the hosts of In a Nutshell ask an important question. Can you get enough calcium on a plant-based diet without fortified foods? And even if you can, do you have to have a degree in nutrition to do the planning? Daisy and Clare provide a lively listen helping us to understand the role of calcium in the diet, and how to make sure you have a good intake as a plant-based eater without obsessing about which green vegetable comes with the mushroom pie.If you'd like to support our work and be part of a growing community of like-minded people working towards creating a healthier and more sustainable future please join the Plant-Based Health Professionals UK following the link below:https://plantbasedhealthprofessionals.com/membership

In episode 8 of this season we discuss the food industry's role in green washing, health washing, and welfare washing.  

Nicola Wilks from Adfree Cities describes how advertising seeks to influence our eating habits and planetary health choices, and why we'd probably be better off making choices without adverts. 

We also hear how cities in the Netherlands want to promote plant-based diets, and on this basis have recently taken steps to level the food industry playing field with a ban on outdoor advertisements for meat.

This week a listener question has prompted us to discuss iron absorption and the effect of anti-nutrients. In particular, do phytates and oxalates in plant foods put us at risk of iron deficiency? Daisy and Clare conclude the answer as ever may be to focus on eating a diverse range of plant foods and not to go too much into the weeds (unless of course they are dandelions- an important source of iron we forgot to mention!)
