Why I decided to be a vegetarian

Disclaimer:
There are many reasons why someone may choose to become a vegetarian or vegan. These are just my reasons, and shouldn't be considered to be the be-all-end-all. I don't claim to be right about everything, and I am not posting this in an attempt to try to convince others to become vegetarian. I'm just posting this so that I can convince others to think about their food and where it comes from.

I hold no judgements against those who do eat meat - in fact, I consider myself a "flexitarian", because I still eat fish a couple of times per week, and I'm willing to eat meat on occasion (e.g. I'm not going to make my mom cook a Tofurkey for Thanksgiving. That said, I will probably eat a lot less meat than in previous years and help out a lot more in making vegetarian options available). I also still eat eggs and dairy in order to ensure that I consume an adequate amount of complete protein, calcium and other nutrients, as I believe that it is better to obtain these nutrients through foods than through supplements (e.g. a calcium or iron supplement that isn't absorbed as well by the body). Call me a hypocrite if you wish, but that's just how I roll.

So here we go.

The Environment

According to PETA:
  • The United Nations reported that the greenhouse gases emitted by the meat industry (includes farming, processing, transportation, cold storage, etc) is greater than that emitted by "all of the SUVs, cars, trucks, planes and ships in the world combined".
  • It takes 300 gallons of water per day to produce a typical vegetarian diet, compared to 4000 gallons per day to produce the typical meat-eater diet.
  • Of all of the fossil fuels and raw materials used in the USA, more than 1/3 of them are used to raise animals for food.
  • The Environmental Protection Agency reported that runoff from factory farms produces more runoff into rivers and lakes than all other industrial pollution sources combined.

The EPA also reported that the world's livestock herds are also the largest source of human-induced methane production. Yikes!

Water is a very precious resource that the world has taken full advantage of. I believe that it is important to preserve out potable water supply, and reduce water usage that is harmful. It takes about 2500 gallons of water to produce one pound of beef, whereas to produce the same amount of soy takes only 250 gallons.

In addition, we have all heard about the effects of methane and greenhouse gases on the environment and their contribution to global warming. By reducing my consumption of meat, I hope to reduce the demand on the market to continue producing meat products in a way that harms the global environment. The American Journal of Clinical Nutrition reported in 2003 that the production of one calorie of animal protein requires more than 10 times the fossil fuel input of one calorie of plant-based protein.

Use of Land and Resources (other than fossil fuels)

In order to produce meat, land must be dedicated to this purpose. This often means that forests and natural green spaces are removed to make way for factory farms. The United Nations reported that an astonishing 30% of the Earth's land is now used to raise animals for food, including space for grazing and the land used to grow crops for feed. It also reported that more than 260 million acres of U.S. forests have been cleared to make way for crops used only for feed for farmed animals.

Farmed animals use an astonishing amount of grain, in a very inefficient way. Animals consume a large amount of grain, but produce a comparitively small amount of caloric content in their meat. PETA reported that more than 70% of the grains and cereals grown in the USA are used for farmed animals. SEVENTY PERCENT! If even a small portion of this grain was diverted from feed for animals into feed directly to people (particularly soy and wheat products), we could develop sustainable solutions to eradicate food insecurity and hunger issues, as well as providing more affordable food solutions.

Health Matters

People do not require meat to live. In fact, there is no nutrient that cannot be obtained through a vegetarian diet or through supplementation for a vegan diet. Meat products do not contain all of the vitamins and minerals that we need to live - indeed, meat is actually quite deficient in vitamins other than the B-complex and contains absolutely no fibre. Saturated fats only exist in meat products. These are the fats that are often linked to heart disease and stroke risk. Studies have suggested that people who consume a vegetarian or mostly plant-based diet have lower risk of many types of cancer, heart disease, and other chronic diseases (although, admittedly, many of these studies may be skewed by confounding factors, e.g. the fact that many people who are vegetarian/vegan also have healthy lifestyles complete with physical activity, not smoking and limiting alcohol).

That said, I admit, there are certain nutrients that are only found in meat products and/or are more easily absorbed by the body when consumed from meat sources. For example, B12 and cholesterol are only found in animal products. Cholesterol has a bad rap, however it is still an important part of our cellular structure. However, vegetarians who still consume dairy and/or eggs will still receive an adequate amount of these nutrients. In addition, supplements are available to help vegans obtain the nutrients they need. Iron is more easily absorbed in it's heme form, only available in animal products, but it is not impossible to receive adequate iron when vegetarian. A new vegetarian MUST do their research to determine how best to gain nutrients like this, and how one can enhance absorption (e.g. eating spinach with vitamin C-rich foods but avoiding calcium to enhance absorption).

Yes, it's true, meats contain complete proteins. However, I've posted before about the fact that it is not at all impossible to build complete proteins from plant-based foods if you have done your homework and know how to complement proteins. All plant foods contain proteins, however most (pretty much all except quinoa) are lacking in some essential amino acid that needs to be added through another food. For example, rice and beans complement each other and build a complete protein. Vegetarians are still perfectly capable of consuming an appropriate amount of protein, but it's very important to do your research to know what you're doing!

So there you have it.

Note that my reasons listed don't involve much to do with animal welfare. That's not to say that I don't care about it at all (I love a fuzzy chick or snuffly pig as much as anyone else!), however the welfare of farmed animals is not among my top priorities for reasons to become a vegetarian. I think that once farmers start focusing more on the environmental and social impacts of their farming, the welfare of the animals may improve as well.

This is also not to say that I won't ever eat an animal ever again. If these conditions change in the future, I will happily give my business back to meat producers. However, I'm choosing to avoid meat products in protest of the negative impacts of farming practices and the social impacts of using the majority of the world's grain for meat rather than feeding the hungry, and using up unreasonably large amounts of precious, non-renewable natural resources (water, fossil fuels) that are in danger on our planet already.

As mentioned earlier, I hold no judgements whatsoever on those who do choose to eat meat or those who choose to be vegan, or any variation thereof. I hope that my choices will also not be judged by others. I only want to encourage people to think about their food sources and understand where their food comes from. There are, indeed, many good reasons to eat meat as well, and many others to remove animal products from one's diet entirely!

30 Day Challenge: Vegetarian Diet and Protein

Hey everyone!

We are now more than halfway through the 30 Day Challenge! Wooooooo!

Being that this is now week 3 of the Challenge, I am still caffeine-free and alcohol-free, and have started adding vegetarian meals to my life. I'm not a very picky vegetarian though - if someone gives me rice that was cooked in chicken broth instead of veggie, I'm not going to freak out over it. I'm still eating eggs and drinking milk, just cutting out meats and fish - basically anything that bled at some point in it's life.

This week's goal was to eat full days of vegetarian meals 3x during the week, but I've already exceeded that :) Sunday, we went to my mom's place for dinner and she served tilapia (mmmm), so there was one day gone. Wednesday night Ed and I went out for sushi (also mmm). But every other day (Mon, Tues, Thurs and Fri) have been full on vegetarian dishes. Woooooo!

I've been experimenting with fun sources of protein, trying to gets lots of variety in plant proteins.

Nutrition Lesson!
There are 22 amino acids, which are the building blocks of protein. Proteins make things like muscles, enzymes, hormones and other great things your body needs. The body can piece together some proteins on it's own (non-essential), but there are 8 amino acids that the body cannot synthesize (essential amino acids). These amino acids must be obtained through food. It is very important to eat a variety of protein sources to ensure that you're getting an adequate amount of each of these essential amino acids.
Meat eaters typically don't need to worry much about this, as meat products tend to be rich in essential amino acids. For vegetarians and those who don't eat a huge variety of meat products though, you need to explore new protein sources to get the full range of essential amino acids. For example, if you eat no source other than wheat, you will be deficient in some amino acids -- lysine is found in very small quantities in wheat and rice. You need to balance it out with other sources, like legumes, seeds, beans, soy, etc. Chickpeas and beans are fantastic sources of protein, as is quinoa, which contains ALL of the essential amino acids!!!

Neat, huh???

So, here are some examples of the foods I've been gobbling this week in an effort to get lots of good plant proteins:

  • Quinoa --- I use it either as an alternative to rice when making stir-fries, or make a quinoa salad by mixing it up with veggies (tomatoes, zucchini, peppers, cucumbers, etc) and herbs (cilantro, parsley, etc).
  • Chickpeas, and other beans --- love them!!! I put them on my salads a lot, and make a lot of hummus and black bean dip to dip my veggies. They're also great in vegetarian chili!
  • Edamame and tofu --- I bought a huge bag of frozen shelled edamame, and just take a cup out, microwave it for a minute, and poof! Steamed edamame! It's great sprinkled on salads, or just lightly salted (sea salt is best) and eat as a snack. As for tofu, I haven't gotten into it yet as a dessert or in smoothies (silken tofu), but I do make a lot of stir fries. I do try to limit my tofu intake though, as there have been some reports about fermented soy products and links to breast cancer. Whether the rumours are true or not, I'd still like to experiment with other protein sources first than eat nothing but tofu all the time.
  • Lentils --- I'm addicted to lentil soup.
  • Nuts, seeds and peanut butter --- mmmmm.... nuts are dangerous territory for me. I could scarf down a whole bag of cashews like THAT *snaps fingers dramatically*. But portioned out properly, nuts can be a great protein source. I sprinkle a tablespoon of walnuts on salads, or just eat walnut halves or almonds with dried apricots as a snack. I've gotten big on pumpkin seeds lately as well (because I bought a box thinking that they looked neat, having no idea what to do with them. So I'm experimenting). Peanut butter, again, is a bit of a trigger food for me, but I eat it sparingly. One tablespoon on my toast or in my oatmeal is all I need to feel peanut buttery goodness and satisfy the craving for the day :)

So since we're talking so much about protein, let's talk about recipes that can help you get them in! I've listed here one recipe using eggs (for those of us who eat them), and one with only plant-based protein.

Southwestern Egg Salad

Giving credit where it is due, I got this recipe from the Weight Watchers website. But I made a couple of small alterations to their recipe, so hopefully I won't get sued for it or something.

3 hard boiled eggs (whole eggs - you could use 2 eggs and 2 egg whites to cut some fat/points)1/2 bell pepper, chopped finely
2 whole red bell peppers
2 tbsp onion chopped finely
1/4 tsp ground cumin
1 Tbsp salsa
1/2 jalapeno pepper, chopped finely (don't touch your eyes!!!!!!!)
1/8c reduced calorie or fat-free mayonnaise. I only had reduced-calorie in the house, so unfortunately, my points value is increased. Fat free would cut the points down :)
Salt and pepper to taste

Peel your hard boiled eggs and place in a large bowl. Mash them up with a fork.

Add all your chopped veggies into the bowl, and the mayo, salsa, cumin, salt and pepper. Mix it all together till it's well blended.

You can eat this on it's own, in a sandwich, or my preferred way, inside those 2 whole bell peppers! STUFFED EGG SALAD PEPPERS!!!!!

With my reduced-cal mayo, this worked out to 5 points per serving. You can get about a 1/2 cup per serving, so this recipe makes 2 servings (about 1.5 eggs per serving). Great for lunch!

Roasted Pepper, Feta and Lentil Salad

Giving credit again, this recipe also came from the Weight Watchers site. Except for the making your own peppers part -- that was all me :)

1.5c dry lentils, picked over to remove the gross stuff
6 cups of water
1/4c balsamic vinegar
1/2c roasted red peppers (canned in water) diced, or make your own ***
1/3 fresh chopped basil
salt and pepper to taste
2tsp olive oil
1/4 crumbled feta cheese

Place your lentils in a saucepan and pour in water. Set it over high heat to boil. When it's rolling, reduce the heat to simmer, covered, for about a 1/2 hour till the lentils are tender.

Drain the lentils and transfer to a large bowl. Add the balsamic vinegar and oil, toss it around to mix. Add your roasted peppers and basil, toss again. Season with salt and pepper.

Serve in 4 bowls, each sprinkled with about 1tbsp of feta cheese. This can be served either warm or cold, and gives about 3/4 cup per serving for 5 Points!



*** Making your own roasted red peppers

Brush the entire pepper with vegetable oil. Note, I learned the hard way (i.e. when the security guard came to make sure I hadn't set the apartment on fire) that extra virgin olive oil should be avoided. It has a very low smoke point, and it will BURN. It doesn't make the veggies taste any different, but it makes a lot of smoke, and makes for a very embarassing situation when you have to explain that your cooking set off the fire alarm.

Turn on the broiler. Put your peppers on a cookie sheet and pop 'em in on the top shelf of the oven close to the heat. Keep a close eye on them --- when you see dark splotches show up, take the sheet out, turn your peppers over (use tongs if you value your fingers, they're very hot), and put them back in.

When they start to get brown again, take them out. Put your peppers into a bowl that can stand the heat and cover with plastic wrap. The heat will move around in the bowl and steam your peppers, allowing the skin to loosen. Leave them alone for 15-20 minutes.

When the peppers are cool enough to touch, pull the stems off. Hold the pepper down and peel the skin off (should come off fairly easily). You can then squeeze out the pulp and seeds, cut them open, and voila! Roasted peppers, ready to use in your lentil salad above, or on sandwiches, salads, bruschetta, etc!

What are some of your favourite ways to get protein into your diet?
