Vegan Mofo #4: The Health Reasons for Going (And Staying!) Vegan

Posted Oct 06 2011 7:41pm

Hi friends,

This is a post that I wrote earlier this summer for the Vegan 101 series on the excellent blog JL Goes Vegan . Even though it’s not completely food-related, I’ve decided to post it here for Vegan Mofo . I hope you enjoy it!

Vegan 101 – The Health Reasons for Going Vegan

As a career-changer to the field of nutrition. I have spent the past several years immersed in all things food and nutrition-related. It was only after I educated myself on the realities of factory farming that I started considering veganism. At that point, I could no longer deny the realities of animal suffering and an omnivorous diet. Finally, on September 16th, 2010, I made the commitment to go vegan.

As a graduate student in public health, I naturally had an interest in the health effects of a plant-based diet as well. I began reviewing the scientific literature on the subject and was shocked by the credible evidence that concludes that well-planned vegan diets are not only appropriate for all stages of life, but can prevent chronic diseases including cancer, heart disease and diabetes (1).

Other conclusions from the research include:

  • Vegans have lower rates of blood pressure than meat-eaters, likely due to lower body mass indexes (2).
  • One study showed an association between beef consumption and fatal ischemic heart disease, as well as showing that cancers of the colon and prostate were significantly more likely in nonvegetarians than vegetarians or vegans (3).
  • Vegetarians have lower rates of coronary heart disease, diabetes and obesity. In addition, vegetarians have lower rates of cancer overall and greater life expectancies than nonvegetarians in the same communities (4).
  • A low-fat, vegan diet has been shown to increase dietary factors that could reduce the risk of chronic diseases including cancer, cardiovascular disease, diabetes and macular degeneration (5).

One book that does a great job in consolidating the evidence as well as reviewing primary research on the associations between diet and disease is The China Study by T. Colin Campbell, Ph.D. (6). This ground-breaking epidemiological study examined the health effects of a plant-based diets on more than 6,500 adults in rural China.

By controlling for location and diet, Dr. Campbell and his team were able to develop statistically significant associations between lifestyle, diet and disease variables. His research boiled down to the assertion that “the same low-fat, plant-based diet that helps prevent obesity also allows people to reach their full growth potential while working other wonders as well. It better regulates blood cholesterol and reduces heart disease and a variety of other cancers.”

Another book that is a great read on the health benefits of a whole foods diet is Eat to Live by Joel Fuhrman, M.D. (7). Dr. Fuhrman has extensively reviewed the literature on a plant-based diet and has put it into practice with thousands of patients.

In Eat to Live, Dr. Fuhrman discusses how heart disease, diabetes, autoimmune disease, heachaces and depression can all be improved, reversed or prevented by our choice of foods. While so many prescription drugs have unwanted side effects, the answer to our health problems may be found in our pantries and refrigerators.

 It was Dr. Fuhrman’s message that gave me hope that by changing my diet to one that was whole foods, plant-based, and low in added sugar, salt and fat, I could possibly decrease my migraine frequency. I cleaned up my diet even more to include a higher number of daily servings of fruits and vegetables. I discovered new and creative ways to enjoy these healthful food items including adding raw greens to my breakfast smoothie , incorporating vegetable juice into my daily routine and making a delicious cashew cream sauce to serve over blanched cruciferous vegetables .

Within a matter of weeks, my migraines diminished in frequency. At this point, I can say that migraines are a very rare occurrence in my life and I cannot express how grateful I am for this positive change. In this way, veganism has given me my life and health back.

In conclusion, I am incredibly grateful for the books, blogs, researchers, medical professionals and advocates who have publicized the important link between a vegan diet and health. There was a time when I realized that I could no longer live life feeling sick and out of control. It wasn’t until I reviewed the evidence that I could heal myself that I made the necessary changes on a daily basis.

If you are yet convinced that a plant-based diet is the answer to many of the health problems that plague us, then I urge you to review the evidence for yourself. Better yet, make the commitment to small changes that include more plant-based foods and fewer or no animal products. The sweet irony is that by choosing to save the lives of animals, we may be choosing to save our own lives as well.
