15 Years of Being Vegan

Screenshot from 2016-06-06 16:08:28.png

It’s official! I have been a vegan for 15 years. Looking back through the mists of time, I vaguely remembered that I wasn’t sure I’d be able to function at all for a year as a vegan, let alone eventually thrive and joggle sub-4 hours marathons. It wasn’t easy at first, but after about 6 months I got used to it and there was no turning back. My going vegan doesn’t change the fact that billions of animals are still getting slaughtered every year for meat, for fur, and in labs, but it’s my own small way to not contribute to this endless horror and hopefully help move things in the right direction.

If you are interested in going vegan, here’s some resources and advice gained from being a vegan for 15 years: First, check out Vegan 101: Planning Healthy Vegan Diets so that you’re up to speed with what you need to know to be a healthy vegan. Not sure what you’re going to eat every day? Then here’s a 21-Day Vegan Meal Plan from the PCRM. Oh She Glows also has tons of vegan recipes so that you never run out of ideas. It’s an exciting time to be a vegan, with so many options out there and growing.

When people come to me for advice on being vegan, I give them advice that is practical, easy to follow, and science-based. Practicality does not mean sacrificing nutrition or flavor, it simply means making the diet and lifestyle easy to stick to for people with busy lives. Rice and beans, pasta and vegetables, oatmeal, and peanut butter(or tahini) and jelly sandwiches are what I commonly eat. I admit I sometimes overdo it with the peanut butter. Tofu is a great source of protein and very versatile.

Whenever possible, buy food in bulk to save money, cook in bulk and don’t believe the fear-mongering about microwaves. You don’t need to buy organic. You don’t need to learn the origin of every food ingredient overnight to see if it is vegan or not, so don’t stress yourself out over this. Take your time learning about these ingredients.

Take a B-12 supplement. You may also require iron, zinc, iodine, calcium, and vitamin D which you can get from some vegan supplements or enriched foods. You can get omega 3s by eating flaxseeds and walnuts. In my experience, people who fail at veganism were probably deficient in one or more of these vital nutrients. They either weren’t supplementing or they weren’t eating enough nutritious, well-balanced meals.

A little over 10 years ago I came down with anemia for a few months, even though I regularly ate high iron plant foods. An iron supplement quickly reversed this and I was back to my regular rigorous athletic activities. Keep in mind that plant iron is much more difficult to absorb than animal derived iron and that vitamin C helps you absorb more iron. Consult a doctor or dietitian before taking anything to ensure you are getting the proper dosage from a reputable source.

Last but not least, ignore the fads. Fad diets come and go, but veganism at its essence is no fad. These overly restrictive diets make it so difficult to stick with the lifestyle that they greatly increase your chances of becoming an ex-vegan, and believe me, I know a lot of ex-vegans. What fads am I referring to? I mean rawfoodism, “clean” eating, paleo-veganism, macrobiotics, gluten-free, alkaline diet, oil-free, “detox” diets, as well as countless hybrids of these pointless distractions. Also, don’t buy into the hype about “superfoods”. My 10 Things That Aren’t Necessary For Being a Healthy Vegan goes into detail about why these diets are nonsensical and potentially harmful.

If you are eating a balanced whole food vegan diet, these fad diets do nothing to improve your diet or make you healthier. By and large, these diets, which have nothing to do with veganism, are based on pseudoscience and virtually no reputable health professionals recommend them. Ignore, or better yet, laugh at the pesky food police on social media who are quick to castigate anyone for adding olive oil to food or eating processed food or nuts in moderation. The gurus who promise perfect health are best avoided.

By following the advice offered above, and embracing science and critical thinking, you shouldn’t have any major issues adjusting to a vegan lifestyle. This is really all you need to know to get started. I hope you found this information useful. If you think I left out something important, please leave a comment. If you have any questions please post something in the comments or email me, I love to help people transition to a more cruelty-free lifestyle.

5 More Things That Aren’t Necessary For Being a Healthy Vegan

Screenshot from 2016-01-24 12:31:45

The long-awaited sequel is here! The post I did back in November of last year titled “10 Things That Aren’t Necessary For Being a Healthy Vegan” was so popular(a big thanks to everyone who shared it), I decided to do a followup. Many things were left out because I didn’t want the post to be too long, so I prioritized the most common things that I believe are problematic. Here are 5 more things you don’t need to be a healthy vegan:

1) Eat alkaline

This form of pseudoscience has a following both within the vegan/plant-based community and misguided health nuts among omnivores. It overlaps to a large extent with rawfoodism, though isn’t necessarily the same thing. The idea behind this diet is that most people eat diets that are too “acid-forming”, and that an acidic environment inside the body can lead to serious diseases, including cancer.

By eating an alkaline diet, you are helping to prevent this unhealthy acidic environment in your body and the diseases it causes. Some advocates go even further and claim it can be used to treat serious diseases. Basically, eating alkaline means consuming lots of fresh fruits and vegetables(since they are generally alkaline), which is excellent advice, though alkaline gurus recommend it for the wrong reasons. There is virtually no scientific basis to this type of diet. You can’t do much to alter your PH through diet, and your body works hard to make sure your PH stays within a very limited range to keep you healthy.

Some medical conditions can lead to a significant shift in PH, which can be dangerous; the medical conditions associated with a PH imbalance require urgent medical care. Assuming you have this type of problem, you cannot fix it through diet. There is no good reason whatsoever to embrace this fad diet and its idiotic restrictions.

2) Give up all grain including bread

One of the hallmarks of disordered eating is avoiding perfectly healthy food for irrational, pseudoscientific reasons. It’s disturbing witnessing all the over the top fear-mongering on social media concerning soy foods, olive oil, cooked food, and even staples like grain and bread. Grain-free is yet another ridiculous, unnecessary restriction that greatly increases your chances of failing at veganism. It’s no coincidence that the zealots pushing this “grain is poison” madness are very often rawfoodists, though they have allies among the paleo, high meat/protein crowd.

At its most basic, the idea behind this type of dietary restriction is that grains will ruin your health because we supposedly didn’t evolve to eat them. Grains cause obesity, heart disease, diabetes, and Adam Sandler movies. As always with pseudoscience based restrictions, there is virtually no evidence for these claims, except that in a generic sense there is a grain of truth to it. Eating too much of anything can lead to health problems, not just grain. Yes, grain isn’t perfect, it contains “toxins” like phytates, but there is no such thing as a “perfect” food or a “perfect” diet. If you had to abstain from something because it contains small quantities of “toxins” and therefore falls short of perfection, you’d have to give up everything and end up starving to death.

Now while a minority of the population are better off restricting carbs or eating high-protein, this approach doesn’t appear to benefit most people. This fad is best ignored. Grain won’t harm you when consumed in reasonable amounts; whole grains are one of the cornerstones of a healthy vegan diet.

3) Focus on super foods

The most important thing you should realize about “super foods” is that this is purely a marketing term, not a special class of food recognized and recommended by reputable health professionals. That said, there’s nothing wrong with eating them, just don’t get carried away with thinking there is something magical about them.

What you really should be focusing on is eating a wide variety of fresh fruits and vegetables. The wider the variety, the better. The criteria for deciding what is a “super food” is usually pretty arbitrary and changes with time and what is fashionable at the moment. Since antioxidants are all the rage right now, “super foods” very often have a high antioxidant content. All too often, the evidence showing some unique medicinal effect for a certain “super food” is weak or preliminary, but that doesn’t stop health guru authors, supplement pushers, and retailers from hyping them. Again, “super foods” can be part of a healthy diet, but there’s no good reason to consume them in supplement form.

Ignore the hype and just eat several servings of fruits and vegetables every day – darker, more colorful ones are generally more nutritious.

4) Go macrobiotic

The popularity of the macrobatic diet waxes and wanes. Right now, this Japanese type diet doesn’t seem all that popular, but all it would take to make it popular again is a major celebrity endorsement. Macrobiotics isn’t a vegan or vegetarian diet(it usually includes fish) but it comes close, so it is easy enough to make it vegan.

For the most part, a macrobiotic diet is pretty healthy(though it can be salty), at least when you compare it to the way most Americans eat. It emphasizes fruits and vegetables, legumes(especially soy), and whole grains. So what’s the problem?

The problem is that macrobiotics is an overly restrictive diet based on pseudoscience. Although it gets a lot of things right, it does so for the wrong reasons. An important feature of macrobiotics are these arcane, complicated food combining rules, the purpose of which is to properly balance the “yin and yang” elements of food to help you achieve optimum health. For example, perfectly healthful members of the nightshade family like potatoes, tomatoes, and eggplant are excluded from this diet because they are considered too “yin”. It really should go without saying that there is no scientific basis to “yin” or “yang”; you could be missing out on a lot of nutritious foods if you follow these nonsensical rules.

There really is nothing macrobiotics can add to an already healthy plant-based diet except unnecessary restrictions, so there’s no good reason to embrace macrobiotics.

5) Go paleo

Finally, the diet that combines the best of both worlds, with incredible health benefits reflecting this best of both worlds approach. However, does it live up to the hype?

The paleo diet, which mimics the way our caveman ancestors ate is thought by proponents to be the ideal human diet since we evolved to eat this way. Or at least that is what paleos want you to believe. In essence, the paleo diet is really just the latest iteration of high protein dieting; it’s more or less a successor to the Atkins diet.

The central idea to paleo is that if you want to be optimally healthy, eat like a caveman. That’s because cavemen ate the way nature intended us to eat, we “evolved” to eat a paleo diet. Since cavemen didn’t eat processed foods, the paleo diet excludes processed foods like refined sugars, oils, etc. This is generally a good idea, though some people get a little too carried away with this. Paleos also typically eat lots of fruits and vegetables, and don’t consume dairy, so it should be easy for vegans to go paleo, right? Only if you ignore the fact that paleos typically eat a lot of meat and generally forgo grain and legumes, and that the diet is followed purely for health reasons.

To me, there’s always been something very oxymoronic about this “paleo-vegan” phenomenon. After all, a great way to describe the paleo diet is “wholefoodism for meat-lovers”. People who think paleo and vegan are compatible or combine well are usually clueless hipsters obsessed with all things trendy. I struggle to think of two things more antithetical than veganism and paleoism.

A lot of half-truths, distortions and pseudoscience underpin the paleo philosophy, but I’m mainly concerned here with how paleo-veganism is often promoted as an improved version of veganism by paleo-vegan adherents. In a lot of ways, it’s certainly healthier than the way most Americans eat, but does it offer anything to vegans?

As far as I can tell, it doesn’t offer anything to vegans except unnecessary restrictions which puts them on a slippery slope to disordered eating. Like I said before, a small percentage of the population may benefit from minimizing grain and carbs, and eating more high protein foods, but one need not go paleo to accomplish this. If you eat a whole food vegan diet, embracing paleo is largely redundant, since you’re already excluding dairy, and eating lots of fruits and vegetables. Science doesn’t suggest that paleo-vegans are healthier than regular vegans, or that this is the best diet.

In my opinion, just ignore this fad or anyone who fancies themselves as a reborn caveman. We already knew that eating fresh fruits, vegetables, and whole foods was good for us, and that dairy isn’t necessary, well before paleo came along.

  ********

These are just 5 more things that may screw up your vegan diet, on top of the 10 from the previous post. I could have easily added several more to this list, but it starts getting repetitive. I write these lists because I am troubled by all the bad health advice that encourages disordered eating being spread on the blogosphere and social media. I run into ex-vegans all the time and I usually find they embraced a type of extreme diet based on lots of terrible advice and/or unnecessary restrictions like those on this list. Vegans shouldn’t be made to feel guilty by fellow vegans for not following some “perfect” version of a vegan diet, when there is no good reason to follow this “perfect” diet. I want veganism to be as practical and evidence-based as possible, not difficult and esoteric.

Pseudoscience and misinformation does nothing to help vegans improve their health, or for that matter, in case you’ve forgotten, live an ethical lifestyle that does not exploit animals, which is all that veganism is supposed to be about.

10 Things That Aren’t Necessary For Being a Healthy Vegan

Screenshot from 2015-11-28 17:07:50

If you are totally new to veganism, please read “The Plant Plate” first. This vegan eating guide by RD Ginny Messina will tell you all that is necessary for being a healthy vegan. That guide basically shows how I eat.

 

If there’s one thing the media can be counted on to do with regularity, it is bashing veganism by conflating it with eating disorders. Every time an ex-vegan blogger or celebrity shares their story about why they stopped being vegan, usually with horror stories about how sick they became, the media and many people jump at the chance to portray veganism as an extreme, unhealthy diet that will ruin your health.

It almost always seems the “vegan” in question was mainly motivated by health fanaticism, and had an eating disorder. Besides this, they were usually a devoted follower of one or more quack gurus who advocate a variety of unnecessary restrictions and practices that have nothing to do with veganism. The only things these restrictions do is make it harder to follow a vegan diet than it should be. They do not make it healthier.

Unfortunately, overly restrictive eating has become a little too common these days in the vegan/plant-based community due to the many gurus who advocate some or all of what is on the list below. It’s time to set the record straight about what really constitutes a healthy vegan diet/lifestyle. However, instead of “here’s what you need to do to be a healthy vegan” kind of post with health tips virtually everyone already knows, I thought I would do it from the other direction. So in the interest of making a vegan diet as easy, practical, healthful, and science-based as possible, here are 10 things that aren’t necessary for being a healthy vegan:

1) Eat only organic

Contrary to what you may have heard, organic isn’t necessarily healthier. Yet many vegans are very committed to eating mostly or nothing but organic due to the belief that conventional foods are laden with disease-causing pesticides and toxins.

The scientific evidence however doesn’t consistently show that organic is healthier. Organic foods also have pesticide residue on them, both natural and synthetic. The amount of pesticide residue is generally minuscule, and much of that can be washed off before consumption. The only thing going organic is almost certain to do is make your vegan diet/lifestyle more expensive.

As far as organic being better for the environment, that is controversial and beyond the scope of this post.

2) Go gluten-free

If you don’t have celiac disease or wheat allergy you don’t need to give up wheat or gluten-containing foods. Strangely, some vegans who don’t have celiac disease adhere to this as if gluten was a form of meat. They could be missing out on a lot of nutritious foods by going gluten-free. To make matters worse, gluten-free products are often more expensive than their gluten-containing counterparts. Save your money and ignore this fad.

3) Detox

On second thought, you actually do need to detox. Fortunately, if your liver and kidneys are functioning properly, this is being done for you automatically. As far as “detoxing” through diet goes, this ritual often seems to be the common denominator of those who become “vegan” as a result of being health-obsessed. All-too-often, I stumble upon a vegan health blog that recommends a juice fasting regimen and/or worthless supplements to help the body “detoxify”. This is pseudo-scientific garbage. It’s a great idea for most people to eat or even drink more fruits and vegetables, but they won’t help you remove “toxins”. If you believe you’ve been poisoned, skip the juice bar and seek medical help.

4) Give up soy

This is very similar to going gluten-free in which a perfectly healthy food is demonized for no good reason. Unless you have a soy allergy, there’s no good reason to avoid soy foods. The idea that eating soy foods will give men feminine traits is hooey. If you don’t have thyroid issues, it’s very unlikely that soy in moderation will interfere with your thyroid.

5) Eliminate processed food 100%

I don’t believe that eating healthy should mean completely abstaining from processed foods. Of course, “processed food” isn’t easy to define, but foods that contain a lot of sodium, added sugars, or other additives is a good approximation. Eating a mostly whole food diet is a good idea, but I don’t think that should mean you can’t occasionally eat processed food like meat analogues for convenience. Studies don’t show that eating some processed foods will ruin your health if your diet is healthy otherwise.

6) Spirulina supplements

This type of supplement, which is derived from cyanobacteria(blue-green algae), is largely marketed toward athletes, vegan and non-vegan alike as an “energy booster” or “recovery” aid. It also supposedly has a plethora of other amazing health benefits that the “ambassadors” who push these magic pills on social media will be quick to inform you of. And it’s all nothing but hot air. I often call it “The Pond Scum Scam”.

While it is true that spirulina is nutritionally dense, and that NASA has done some research on it, there’s nothing unique to it that you can’t get from other plant foods for a lot less money. There’s also the potential for contamination and vitamin B12 analogue issues with this type of supplement, not to mention the unpleasant “fishy” taste some users complain about. Even though I’ve never tried them, the pseudo-science used in the promotion of these expensive supplements always left a bad taste in my mouth. Ignore the hype and just eat plenty of fruits and vegetables, and eat trail mix or an energy bar after a vigorous workout.

7) Go 100% raw

I’ve already covered rawfoodism in “My Position on Rawfoodism“, but it deserves to be mentioned here because many of the “vegans” with eating disorders who fail at “veganism” were actually rawfoodists. It just really bothers me how much rawfoodism is intertwined with veganism these days.

As a former rawfoodist, I believe rawfoodism has little to do with health and is more about attaining some bizarre, quasi-spiritual level of “purity”. It’s difficult to find a justification for this kind of diet that isn’t based on some form of pseudo-science or the naturalistic fallacy. It’s even more difficult, in my experience, to stick to this diet. People who are drawn to this diet are often extreme perfectionists.

I keep hoping this dangerous fad will go away, but for some reason it continues to linger on as a thorn in the side of the vegan movement.

8) Give up all oil including olive oil

Already covered this here, but this also shows no sign of going away in spite of the potential for this to alienate the many millions of Mediterraneans, Hispanics and millions of others who love their olive oil. Besides this, fat helps you feel full and also helps you absorb fat-soluble nutrients. The tiny number of doctors and researchers who advocate this approach all seem to live in this bubble that is impervious to the latest scientific research which contradicts them. In moderation, fats like olive oil are healthful, and won’t ruin the health of vegans who eat a healthy diet.

9) Buying a Vitamix

The purchase of a Vitamix is often thought of as an important milestone in many a vegan’s journey. I don’t have one, or any blender for that matter, and neither do many other vegans I know, but some vegans can’t live without it.

Unlike other things on this list, there’s nothing wrong with purchasing a Vitamix or blender to make smoothies or prepare meals, it’s just that I don’t see it as being absolutely necessary. It’s great if you have one, but it’s also great if you don’t have one. I can just as easily eat my vegetables in salads, soups, sauces and pasta dishes without one.

10) Eat “clean”

“Clean eating” can loosely be thought of as combining most of what is on the list above. It can sort of be thought of as an umbrella term for eating organic, all-natural, whole food, and additive-free, often with a good helping of raw foods. Note that I didn’t say “animal food free” – “clean-eating” in essence has nothing to do with veganism or eating 100% plant-based for that matter. Granted, some health vegans may think of their diet as the ultimate “clean” diet because to them animal foods are totally “unclean”, but this ignores the fact that most “clean eaters” are not vegan.

“Clean eating” overlaps to a large degree with rawfoodism, and has similar motivations in that it’s based on an obsession with purity.”Clean eating” is also interrelated with detox pseudo-science, since if you should fail to adhere to your strict “clean eating” regimen for even one meal, all you gotta do is “detox” to reverse all the supposed negative health effects the toxic food caused. Since so many different, and mutually contradictory dietary approaches are embracing the “clean eating” trend, it can’t be rigorously or universally defined. Indeed, except to the extent that it implies a health or purity obsession, or an embrace of pseudo-science, “clean eating” is almost meaningless.

Besides all this, “clean eating” smacks of dietary elitism, and the sooner we get rid of this annoying term, the better.

*****

These are just a few of the things vegans don’t have to do to be healthy. I could have listed many more, but I didn’t want to go on forever. I chose to list these not just because of how common they are but also because of how they increase the chances of failing at veganism. To the people who continue to advocate things on this list: Please stop making veganism more complicated than it has to be!

If you think I missed any big ones, feel free to mention them in the comments.
