I have recently discovered the joy of Coursera, a wonderful resource for anyone with a passionate love affair with learning. In short, by making an account, you can sign up for free courses made by Ivy League schools and other very highly rated universities. Some are able to be completed for credit. Almost all of them are interesting if you just like learning new things and having a set-out curriculum.
Anyway, I found this lovely site and signed up for 3 courses (The Fiction of Relationship, The Social Context of Mental Health and Illness, and Nutrition for Health Promotion and Disease Prevention, if you're curious). All of them have been wonderful, but the third course has unfortunately been driving me crazy, for reasons entirely unrelated to the teacher (who has been doing a very good job).
Let me say this flat-out. I am not vegan for health reasons and do not advocate it as the perfect health diet. I partake in health research simply because I like to see what science is discovering about how to eat well, and because I have an uncommon diet for which precautions are occasionally necessary. I like to eat a lot of greens, and I don't like to eat things from a box or a TV dinner, but I am by no means an expert, a guru or even a health nut. I am also not qualified to tell you what to do or what to eat.
However, far too many people in this course have the slightly disconcerting idea that they know everything about the perfect diet in the world, and it is their job not to watch lectures and complete assignments, whilst learning about what mainstream science has to say, but to search for pointed counter-studies to everything that the professor alleges and push their biased agenda. It's all too common and has made the discussion forums of the course, where I love to go in my other two courses to share ideas and learn new things, a place for bickering and superiority. It goes something like this:
"Hi, I'm joining this course because I'm a vegetarian and I want to hear the professor say why vegetarianism is the healthiest thing on the planet!"
"That's idiotic. Paleo diets are the best. Anyone who eats grains is going to gain ridiculous amounts of weight and suffer from numerous vitamin deficiencies. Also, nothing anyone says will convince me otherwise."
Some people who believe in other diets are speaking too, but it's mainly an argument between veg*ns and paleos. I don't like it at all. Why?
Because first of all, veg*nism is an ideological diet; in other words, its founding principle is ethics and assuming that science and nutrition naturally line up with these ethics is biased and hence a bad idea unless you have some very strong evidence. While nutritional needs can be met on a vegan diet (and many people do thrive on the diet, myself included) it does NOT mean there is not some healthier or equally healthy mix out there.
Furthermore, a paleo diet may have merit (and of course does, for lots of people) but it lacks the backing of significant research and professional attention that a diet purported in a widely distributed nutrition course would have. Doesn't mean it is absolutely not a good diet, but the jury is still out.
So, in short, the problem is that neither party, veg*n or paleo, has any right to claim that they know the answers. Each one has some research in favor, and some research against. Both are armed with anecdotal stories. Neither are armed with something definitive.
This issue is easily summed up by an old saying: If you meet the Buddha on the road, kill him.
"Buddha", in this turn of phrase, indicates anyone who claims to know everything or have all the answers. They claim to be a god, with prophecies that are unquestionably true. The philosophy is that if anyone is not constantly seeking truth and questioning everything, then they are not following an honest path and are leading you astray from the road to real enlightenment. Someone who supports the scientific method will undoubtedly find worth in this philosophy; after all, the foundation of science is to repeatedly test one's observations to ensure they stand the test of time.
As a vegan, it is tempting to claim that the diet is ideal. However, my ethical choices do not make it so. Only research can indicate whether it is a good idea for health reasons. For now, vegans, vegetarians, etc. must understand that in the pursuit of truth, we must be willing to accept what appears. Even the idea of veg*nism may become outdated due to future ethical discoveries or an even better way to care for the world around us; let us not let our traditions and preconceived notions lead us away from the pursuit of understanding.
