This is our traffic light system for a whole foods, plant-based diet. It describes a diet based on whole grains, legumes, vegetables and fruits with small amounts of nuts and seeds. It is consistent with the disease healing diets of Drs McDougall and Esselstyn as well as the Mastering Diabetes approach to reversing insulin resistance. We do not consider the low-fat approach to be controversial or outdated, it’s simply what has been shown to work and is what we observe in clinical practice.

You may notice that flour products, even 100% wholemeal, is now in the yellow light section. Please read Jeff Novick’s ‘Clarifying Carbohydrates’ piece which discusses the levels of processing of carbohydrates, especially whole grains. Our improved understanding of the gut microbiome has given us more reason to choose less refined grain products – the processing and milling of grains leads to greater absorption in the small intestine, thereby reducing the ‘resistant starch’ that makes it through to the colon. The short chain fatty acids that gut microbiome produce from resistant starch and other forms of dietary fibre support health throughout the body. Whole grains, legumes and/or starchy vegetables are key ingredients of a whole foods, plant-based diet.

The traffic light system provides flexibility for individual needs. If you are lean and healthy and have high energy needs, you may wish to eat more foods from the yellow light section. But if you are trying to lose weight, reverse chronic disease or reverse insulin resistance then you might minimise foods from this section. For optimal health, most of your food choices should come from the green light column.

You will find our traffic light image on our ‘What is a Whole Foods Plant Based Diet?’ page, along with a link to Jeff Novick’s article - www.wholefoodsplantbasedhealth.com.au/going-plant-strong/what-is-wfpb-diet/
