Vegan Diet: Being a Healthy Herbivore

Posted: 09/02/11 08:00 AM ET

When I announced I was making the change over from vegetarian to vegan I got a lot of questions about my diet: Where will you get your protein? What about your iron? And B12? As with any dietary choice, whether omnivore or vegan, you need to be aware of your nutrient intake. So all of this started me thinking, where might I get these nutrients?

Where do you get your protein?

The plant world is full of a wide variety of nutritious and complete proteins! Here are some of my favorites:

• Hemp seeds -- Two tablespoons of hemp seeds can contain roughly 10 grams of high-quality plant-based protein. In addition to the protein, I believe hemp is a source of Omega 6 and Omega 3 fatty acids. Hemp protein is great in smoothies and hulled hemp seeds can be sprinkled on any salad or pasta dish.

• Chia Seeds -- I think Chia seeds are small but mighty! Chia seeds can contain complete proteins and Omega fatty acids. Chia seeds can be added to smoothies and they also make great pudding! (http://thehealthyherbivore.com/2011/07/08/raw-chocolate-chia-hemp-pudding/)

• Quinoa -- This nutty grain contains protein and can be used in a variety of ways. You can eat it for breakfast in place of oatmeal, use it as a base for stir-fry and you can even puff it and eat it like popcorn.

These foods, among others, can increase your protein intake. What about iron?

• Spinach -- I think spinach is a powerhouse when it comes to iron. One cup of spinach can contain around 6.4 mg of iron. I believe two cups of spinach is a good addition to a salad.

• Pumpkin seeds -- This small but nutritious seed can contain roughly 4.2 mg of iron per 1 ounce. Try pumpkin seed butter on toast with some cinnamon and agave. Pumpkin seed butter is a flavorful thickening agent for sauces as well. In this recipe simply replace almond butter with pumpkin seed butter and viola!

• Lentils -- Lentils are an extremely versatile bean and contain 7.5 mg of iron per cup. I like to cook a batch of lentils and store in the fridge to toss with salads or wild rice pasta.

Now what about B12?

• Nutritional yeast -- Nutritional yeast has a cheesy flavor and can be added to any sauce, pasta dish, or side of veggies. It's also a great topper for popcorn! Two rounded teaspoons of high-quality nutritional yeast can provide 2.4 micrograms of B12.

• Cultured and fermented foods -- I believe foods such as tempeh and miso are good sources of B12. Not sure what to do with your tempeh? Try this recipe for tempeh crusted steaks!

• Dulse -- Dulse is a red seaweed that grows on rocks. Dulse is one of the few sea vegetables that contains what I believe to be the proper bioavailable analogue of B12. Three grams of dulse can contain .39 micrograms of B12. There are a few ways to get dulse into your diet. I like to buy it in flake form and add it to smoothies and sauces. It is also great in vegan Ceasar salad dressing!

The foods I've listed are some of the sources for these nutrients however there is protein, iron, and B12 in many other foods in a plant based diet as well. By eating a wide variety of foods, and including the ones listed above, you can be a happy, healthy herbivore!

I can get two of those items where I live. I can get only one year-round. So, accurate or not, this article is really only useful for people in large cities or who want to live off mail-order.

The one item is spinach, but kale (which I grow alongside chard) has a higher nutritional value.

Most stores carry nutritional yeast.

And I've never been in a store that didn't carry lentils.

Yes you're right I forgot lentils. Nutritional yeast, no. Baking yeast yes. I really like nutritional yeast on popcorn,

iherb.com is REALLY cheap when it comes to delivery. Hell, I order from them all the way to Asia, and shipping is usually between 7 and 20 dollars (depending on weight) and I get packages within a week. Give it a try.

Candice - I'm sure you have the best intentions, and I'm not accusing you of purposely misleading anyone, but spreading misinformation, such as that bioavailable B12 is present in tempeh, miso, etc., has the potential to harm a lot of people.

The foods you mention, as well as nutritional yeast that hasn't been artificially fortified with B12, may in some cases contain B12 analogues, but that's not the same as containing B12 in a form which the human body can actually utilize. B12 deficiency is NOT, I repeat NOT, something you want to play around with.

If you're going to be vegan, you need to do one or more of the following:

1) Supplement with B12 in pill or liquid form;
2) Eat B12-supplemented foods, like fortified cereal or fortified dairy alternatives;
3) Take B12-supplemented nutritional yeast, such as Red Star's "Vegetarian Formula".

Even vegan organizations acknowledge the need for vegans to supplement with B12:

Thank you for your comment and I am certainly not trying to mislead anyone. I concur that supplementation may be necessary for B12 but I think firstly it should be attained from food sources, if possible. I am fully aware of the effects of B12 deficiency and it's not something I would "play around with". The sources I have listed I have researched extensively! There are many foods that claim to contain B12 but don't, I know this, and have kept them out of this article.
In retrospect I should have noted that your Nutritional Yeast needs to be fortified and eating fortified foods is necessary. My apologies and thank you for the info!
Cheers!

Your source actually says the opposite of what you claim regarding tempeh, etc.:

"The only plant foods which have been tested for B12 activity using the gold standard of lowering MMA levels in humans are dried and raw nori from Japan. Dried nori made MMA status worse, indicating that it can reduce B12 status and can possibly harm people who are B12-deficient. Raw nori kept MMA levels about the same, indicating that it didn't harm B12 status, but it did not help either.

. . . [O]nly tempeh in Indonesia or Thailand, dulse, Chlorella, raw nori, Aphanizomenon flos-aquae, and coccolithophorid algae warrant much further attention for providing B12. Unless these foods are shown consistently to correct B12 deficiency, VEGANS SHOULD NOT RELY ON THEM AS A B12 SOURCE [emphasis added]".

Additionally, despite claims that unwashed organic produce can contain B12 from surface bacterial activity, the article goes on to state: "Unless uncleaned, organic produce is shown to lower MMA levels, it is unjustified to claim that B12 can be obtained in such a manner, or to claim with certainty that humans have ever relied on it as a source of B12".

And, as the article astutely notes, "The vegan movement is typically not aiming for a world where there are enough cows to produce a significant amount of manure for fertilizer".

When you cite sources to back up your claims, it's a good idea to make sure that they actually agree with what you're saying!
08:58 AM on 09/03/2011
By the way, I'm not trying to be cantankerous or anything, and I appreciate your willingness to be open to correction. It's just that I'm worried that people are going to come across your article and think to themselves, "hey, all I have to do as a vegan is to make sure to eat tempeh, miso, and dulse, and my B12 needs are taken care of". Maybe you could edit your article to clear up that misconception?

As a side note, I like tempeh. I like to crisp up some tempeh and use it as a topping on salads, and I like to throw a teaspoon of hacho miso paste into soups, stews, etc.

I just don't kid myself that I'm getting bioavailable B12 from any of these items.

(Disclaimer: I'm not a vegan, so I get my B12 from animal products. But I have friends who are (vegan, that is, not animal products LOL!!), and I want them to live long and healthy lives, too.)

Candice... You need to do some more research. Nutritional yeast only contains B12 if it's been fortified. Read the labels. And none of those other foods contain B12.

Also, not only is the non-heme iron found in plants harder to absorb, leafy green vegetables, lentils and grains actually interfere with the absorption of iron and other minerals.
06:45 AM on 09/03/2011
Thank you for your comment! I realize Nutritional Yeast has to be fortified but the fact remains that it's still a source of B12 for Vegans.

I also realize non heme iron is harder to assimilate which is why Vegans need to make sure they are eating an abundance of Iron containing foods along with foods that make it easily absorbable such as foods high in Vitamin C and avoid foods that are contain Phytates (like the ones you have listed there). As with any dietary choice, omnivore or vegan, you just have to be aware of your nutrients.
Cheers!

Then you should have pointed out that unfortified nutritional yeast has no B12. Also, the oxalates in spinach and other leafy green vegetables will interfere with the absorption of iron, calcium, zinc and other minerals. To be on the safe side, I recommend that you take a daily supplement that includes vitamins and minerals. Or even better, do a little more research before you make the leap.

The problem with plant based protein is that they are incomplete and need to be mixed, often with high sugar carbs, leaving vegetarians with weight problems. Yeast is not very palatable to a lot of people. It can all be done but it is actually a lot simpler and equally healthy to eat a balanced nutritional program.
The point is, to be vegetarian is a philosophical choice, not a scientific one.

It is true that vegetarians can have weight problems if they focus on carbs, but it is not true that you can't get complete proteins without eating an overbalance of carbs. I don't understand your claim that being a vegetarian is not "scientific". There are lots of plant-based diet cultures that would disagree with your statement here.

It is very possible (and "scientific") to eat a healthy, balanced vegan or vegetarian diet, but it takes some effort to read up on foods, buy fresh produce in season, and prepare it- more effort than stopping for a cheeseburger supersize meal, but not more effort than eating a healthy animal-based diet. Those of us who choose to eat this way usually find that effort worth it.
08:37 PM on 09/02/2011
Thank you for your comment unfortunately I have to disagree. A source of complete protein by definition is something that contains all 9 essential amino acids. There are many plant based sources of complete protein, some I have listed above. I believe you are referring to 'protein combining' such as combining rice, which has a limited amino acid of lysine, with beans which are the compliment to make the meal contain a complete protein. While most people become vegetarian or vegan for ethical, and I suppose what you are referring to as philosophical reasons, there is an abundance of supporting scientific evidence to prove that a vegetarian and vegan diet is ideal for everyone.
12:04 AM on 09/03/2011
Sorry sis, it isn't that easy. The human body is not a lab bench. While there may be analytical data about plant based nutrient value, the fact is that our digestive systems aren't equipped to get them from these sources in close to the healthy amounts. Not to mention some of the metal leaching qualities of protein sources such as legumes. Making the statement "there is an abundance of supporting scientific evidence to prove that a vegetarian and vegan diet is ideal for everyone." only makes you seem disconnected from reality. This type of eating may work for you for a while, but over the long term you will suffer some physiological effects of ignoring your bodies need for some animal products. Eating a plant only based diet also harms the environment in the long term. We're down to the last 4 inches of fertile topsoil because of current ag practices. Animals, insects and microbes are required to return nutrients to the soil, so it isn't all rainbows and unicorns for everyone if you choose to eat in a manner that thumbs it's nose at what we have evolved eating and is detrimental to our planet. Find out about CSAs and add some balance to your diet by keeping an open mind regarding nutrition. Please!

"I believe foods such as tempeh and miso are good sources of B12"
"I believe hemp is a source of Omega 6 and Omega 3 fatty acids"
"I think spinach is a powerhouse when it comes to iron"

So... do you "believe" and "think" these things are healthy, or did you read the research and "know" these things to be true?
07:34 PM on 09/02/2011
Ok so, editorial error. This was my first post on Huffington and was submitted without references so all claims had to be changed of course. If you want here are my sources:
http://www.whfoods.com/
The Encyclopaedia of Healing Foods (Michael Murray, ND)
Nutrition: Concepts & Controversies (Sizer FS, Whitney E, Piche LA. 2009)
Principles of Biochemistry (Horton, 4th Edition)
Role of essential fatty acids in the function of the developing nervous system (Uauy R, Peirano P, Hoffman D, Mena P, Birch D, Birch E.)

Sorry for the confusion. I can assure you any information given is backed with research.
Cheers!

Let's not get into my personal opinion about veganism. But wherever you have written "I believe" you should replace the words with "according to...". It hurts the credibility of the article because it makes it appear your writing is based on something you heard someplace a while back, rather than real sources.
06:13 PM on 09/06/2011
It was a great first article, keep up the good work. And congrats on being newly vegan! Have you tried any of the vegan cheeses? One thing I always tell to new vegans is to avoid vegan cheeses for a few months. Otherwise you'll have the taste of cheese fresh in your mind and when you try the vegan stuff you'll be disappointed. Many of my omnivore friends are totally OK with Daiya, though. One of them even thinks the cheddar is better than the real stuff.

The iron in spinach is not particularly nutritionally available. You have to eat a lot of it to get the same amount of iron in a good, range-raised, steak.

Eating fruits or veggies that contain vitamin C improves the availability of the non-heme iron and let us not forget the numbers of meat eaters who suffer from anemia so this is not exclusively a vegan problem.
