Sometimes, friends ask me, "If we are already vegan (in other words, we don't consume any animal products), what is the advantage of diligently removing processed foods from our diet?"
Dr McDougall

(2008) The Fat Vegan (2008) by Dr McDougall offers a perspective.

(2002) Are You a Sickly Vegetarian (Vegan)?

Veganism & AICR Guidelines

In his webinar on Cancer & Fasting, Dr Greger compared how well various diets stack up against 10 Recommendations by AICR (American Institute for Cancer Research). Turns out that Veganism is excellent for one recommendation: 'Limit Consumption of Red and Processed Meat'. However, Veganism fares poorly as far as four other recommendations are concerned: (a) refined grains, (b) alcohol, (c) sugar sweetened beverages, and (d) fast foods and other processed foods (high in fats, starches or sugars). Additionally, it says nothing about (e) exercise and (f) achieving and maintaining a healthy weight.

Dr Greger

In Dining by Traffic Light: Green Is for Go, Red Is for Stop (2018), Dr Greger says:

That’s why, from a medical standpoint, I don’t like the terms vegetarian and vegan, because they are only defined by what you don’t eat. When I taught at Cornell, I had vegan students who appeared to be living off of French fries and beer. Vegan, perhaps, but not terribly health-promoting. That’s why I prefer the term whole food plant-based nutrition. In general, the dividing line between health-promoting and disease-promoting foods may be less plant- versus animal-sourced foods, and more whole plant foods versus most everything else.

In this short podclip, Dr Greger says:

"A vegan diet is defined as not eating animal products, and often times also has other stipulations like 'not wearing animal products'. But from strictly dietary point of view, 'no animal products!'. But that means you can live off of french fries and beer and cotton candy, and have a strictly vegan diet, and have a horrible diet!"

(2020) Is Vegan Food Always Healthy?

(5 mins) Is Vegan Food Always Healthy? explains that in addition to 'no animal products' guideline followed by vegans, adherence to 'no processed foods' guideline would boost health significantly. Towards the end, he explains this point with respect to diabetes risk.

(2020) Vegetarians and Stroke Risk Factors — Vegan Junk Food?

(8 mins) Transcript. Dr Greger's summary: "Just because you're eating vegetarian or vegan doesn't mean you're eating healthy."

(2015) Do Flexitarians Live Longer?

(4 mins) Transcript. This video explains that the simple guideline of 'eat more plant foods' is effective in promoting health. The more behaviour patterns we adopt for boosting (health, non-processed) plant food consumption, the more the impact to our health.

(2015) Stool pH & Colon Cancer

(5 mins) Transcript. The main point of this video is that high clonic pH (reflected in stool pH) is associated with high colorectal cancer risk. At offset 4:03, Dr Greger explains, "Remember these two groups? Dramatically different stool pH, yet both groups were vegetarian. But the high risk group was eating mostly refined grains, very little fiber, whereas the low risk group was eating whole grains and beans, packed with fiber for our fiber-friendly flora to munch on."

An amazing lecture by Dr Greger in which he explains how becoming 'vegan' may not reduce our risk for heart disease and stroke. What to do? This is a great video for adopting a 'healthy vegan diet' aka Whole Food Plant-Based guidelines, with special emphasis on the role of omega-3 vs omega-6 ratio, flax seeds, arachidonic acid, and so on.

Dr Klaper
(9 mins, 2020) Vegan vs Whole Food Plant-Based

I love this video for an interesting viewpoint! Through adoption of veganism, we help myriad animals avoid suffering. But with the rise of veganism, the processed food industry has responded with a panoply of processed vegan foods (which are counterparts of processed non-vegan foods): vegan pastries & pizzas, vegan candies & ice-creams, and so on. All this is wonderful from a vegan standpoint as it avoids the suffering of many animals. But there is one animal that continues to suffer: humans! [I smiled when Dr Klaper said that] To alleviate that animal's suffering (human suffering from modern chronic lifestyle diseases), we need to adopt Whole Food Plant-Based guidelines.

Dr Heather Shenkman

In the article That Time I Stented A Vegan (2018), Dr Heather Shenkman describes a man in his 50s who had been inspired to go vegan after watching Forks Over Knives. However, his heart showed abnormalities, necessitating a stent. The man then adopted Esselstyn-style strict Whole Food Plant-Based guidelines. An excerpt from the article:

So what happened, why did a vegan have an unstable angina event? He had risk factors for heart disease, which included a family history, high blood pressure and abnormal cholesterol. Also, while he was a vegan at the time of his event, he had spent most of his life on a standard American diet, and his vegan diet probably wasn't the healthiest. Remember, Oreos, potato chips, Twizzlers, and Pepsi are all vegan, but they're certainly not health foods.

Kate Dunbar's Story

Case Report: Managing Psoriatic Arthritis With a Whole Food Plant-Based Diet: A Case Study by Marta Lewandowska, Kate Dunbar and Shireen Kassam, Am J of Lifestyle Medicine, Feb 2021.

Abstract: A 40-year-old female teacher presented to the rheumatology clinic in 2003 with nonspecific back, knees, and right ankle pain. She was subsequently diagnosed with psoriatic arthritis and was taking methotrexate to control her disease. Over the years, her symptoms were mostly under control. However, in 2018, after adopting a whole food plant-based diet free of added salt, oil, and sugar, she was able to stop taking methotrexate. She was discharged from the rheumatology clinic and has remained symptom-free since. The available literature on managing psoriatic arthritis with diet shows that less than 2% of patients with psoriatic arthritis are able to discontinue medication as a result of disease remission. This case report adds to support and encourages further research in the field of managing inflammatory polyarthropathies with diet and lifestyle.

The case report above (published in Am J of Lifestyle Medicine, Feb 2021) is actually co-authored by Kate Dunbar herself. She turned vegan about 13 years ago — it helped her psoriasis but not entirely. In 2018, she turned Whole Food Plant-Based, SOS-Free (ForksOverKnives diet + no-salt) to say goodbye to psoriatic arthritis!

Kate Dunbar shares her personal story in a blog entry too: Reversal of psoriatic arthritis with a whole food plant-based diet (2019), hosted by Plant Based Health Professionals UK. What was the difference betweeen her Vegan [Before] diet and her WFPB-SOS [After] diet?

Source: Managing Psoriatic Arthritis With a Whole Food Plant-Based Diet: A Case Study by Marta Lewandowska, Kate Dunbar and Shireen Kassam, Am J of Lifestyle Medicine, Feb 2021.

Kate Dunbar's personal story is a rare case report published in medical literature in which the shift in meals was from a Vegan to WFPB SOS-Free diet.

  • Kate's Vegan [Before] diet had lots of processed foods (with "oil, textured vegetable protein, vegan cheese, vegan sausages, soy cream, vegan mayonnaise, soy margarine, pastries, cakes, biscuits, ice cream, hummus, sugar"), refined grains (white flour, white rice), very few beans, veggies and fruits, no nuts and seeds.
  • Kate's WFPB SOS-Free [After] diet reduced processed foods to only soy milk, sauerkraut and occasional use of soy sauce and miso. Nuts and seeds were introduced (1+ servings). Serving sizes of veggies, fruits and beans (pulses) were boosted. Grains were exclusively whole grains (no refined grains). An SOS-Free diet has no Salt, Oil or Sugar.
