Some are based in fact and presented in a nonbiased way, whereas others are very biased and filled with personal stories and accounts.

Save yourself from the hours of streaming that I did, and take a look at this list of the best vegan documentaries and worst plant based diet documentaries.

Overarching Messages From These Plant Based Diet Documentaries
Many of these documentaries are issuing a similar message just in a different way. Here's a quick summary of the benefits of a plant based diet.
A vegan diet, centered on whole, plant-based foods like fruits, vegetables, legumes, whole grains, and nuts, offers a surprising range of benefits. Studies like the China Study suggest the health benefits of a plant-based diet can include weight management, lower blood pressure, and reduced risk of heart disease and type 2 diabetes. Vegan meals are often rich in fiber, vitamins, and antioxidants, promoting overall well-being. Despite what critics say, you can achieve all of your dietary needs through plant-based nutrition.
Beyond personal health, veganism has a significant positive impact on animal agriculture and the environment. Modern day livestock cultivation is inhumane, cruel, and dangerous to it's workers and neighboring communities. Factory farms, which raise a vast majority of our meat and dairy, contribute heavily to greenhouse gas emissions, deforestation, and water pollution. By choosing vegan, you reduce your reliance on this system, lessening its environmental footprint.
What they don't tell you is that going vegan or going plant based is a huge lifestyle change that takes an extraordinary amount of commitment. By simply opting for plant based foods, you won't have an optimal diet. There are a lot of nutrition experts in these documentaries who offer valuable advice if you decide to make the transition to a plant-based lifestyle. Always speak to your doctor or health care provider for advice on if this diet is right for you.

Worst Plant Based Diet Documentary Shortlist
These plant-based diet documentaries didn't make the cut for a number of reasons. Mostly because they weren't rooted in facts, substantiated by data, or were simply too one-sided.
What the Health (2017)

The 2017 film, “What the Health” is a plant based diet documentary that investigates the links between diet and health. What the Health challenges conventional dietary advice and advocates for plant-based eating.
What puts this on the worst list is that “What the Health” promotes a plant-based diet as the cure-all for a variety of chronic diseases, presenting dramatic personal anecdotes alongside interviews with some health professionals.

A newer film, “You Are What You Eat: A Twin Experiment” came out in 2024. It explores the impact of diet through identical twins switching to vegan and omnivore diets. As a twin, this documentary intrigued and resonated with me. It's different than other plant based documentaries because it takes a comprehensive view of the role of genetics and lifestyles in nutrition. It did demonstrate some positive effects in the space of inflammation for the twins who ate a plant-based diet.
However, the documentary has been criticized for its bias towards veganism, focusing primarily on its benefits and neglecting a more balanced view of both dietary approaches. While the concept was interesting, many of the subjects in the documentary admitted they did not stick to the diet.
