Episode 16: The Great Protein Debate - Beef or Beans?

Ep.16 Show Notes

In this Skin Flints episode, Sue, John and Paul welcomed Dr Arielle Griffiths to the platform to discuss a very topical subject - sustainable pet food.

(00:00) Introduction

Chapter 1: “Understanding the Urgency: Why Sustainable Food is Necessary for Our Pets”

(03:44)  John welcomes Arielle to the pod, who talks about her work in the industry and in setting up the Sustainable Pet Food Association. As a GP vet she became involved in nutrition and did extensive research before also becoming environmentally and sustainably focused as a result of seeing a change in the world.

(07:31) Sue asks Arielle to clarify what is meant by obesity-based diets and Arielle says this is where owners are (through love) overfeeding their pets and potentially causing arthritis, heart disease and a number of conditions relating to the excess weight. This tipped her to realise the use of plants as a base in food can really help, which was a big factor in her  becoming vegan herself.

(09:08) Sue clarifies we are talking about people feeding too much or an imbalanced diet and the carbon footprint of that diet – and that we are discussing dogs here and not cats. Arielle says that the need for palatability in foods has resulted in an excess of protein in the diet and more meat being used than needed, affecting the sustainability. She shared that wet, meat-based diets have the largest carbon footprint, including raw lean diets – with one study in Brazil demonstrating a dog on this diet matched that of a human in that country.

Chapter 2: "Exploring the Landscape: What Constitutes Sustainable Food?"

(11:49) John asks why vegetarian or vegan food is a more sustainable option and Arielle says it is proven that animal agriculture for the use in pet food accounts for 2.5 - 3% of the entire carbon footprint of the world. This comes from deforestation to provide this food and the by-products of the food as a result of the market.

(13:40) Sue clarifies this as methane production from the animals used increasing the carbon emissions along with the deforestations. Livestock accounts for over 70% of global farming land use but only produces 18% of the world’s calories and 37% of total protein - with dog and cat food being equivalent to an entire country’s worth of production. But Arielle says the health benefits are what turned her more to vegetable based foods. 

(15:29) Sue comments on the information on the human side for the health benefits, with more GPs suggesting it – she asks if there is evidence to support this on the pet side. Arielle says there is and comments on how in the 27,000 years of domestic evolution dogs have developed to require 52% of their diet to be carbohydrate due to the change in their genes over that time compared to the wolf they descended from, which only needs 1.2% carbohydrate. She also says dogs 3,000 years ago were primarily plant based.

(17:09) John asks if the theory of raw feeding being more natural for dogs is therefore unmerited and Arielle agrees, explaining that dogs obviously love eating food like this which is the success of the industry – but in terms of the environment there is significant evidence that resistant bacteria has been shown to be happening as a result of raw feeding, as well as it not being healthy for the dog. And she reiterates - a dog is not a wolf!

(19:18) John goes on to clarify Arielle is advocating a formulated dog food which is vegetable based and asks if it could be insect based. Arielle says it could and there are a number of companies for this, but she focuses on vegetable based and insects are just using another way of recycling protein and therefore whilst they are more substantiable – they are not as much so as the vegetable equivalents. She mentions how she was one of three vets speaking on the s
