A rant about science (alternately: All Hail Nuance and Skepticism)

· · 4 Comments

Warning: this post falls squarely into the category of “cantankerous rant about thing I should probably stop getting so worked up over.” You’ve been warned.

I’ve noticed a troubling tendency in some scientific communities (maybe I should put “scientific” in quotes…I’m lookin’ at you, Facebook) to treat science as some kind of Truth, where certain issues can no longer be questioned or examined because “science” has already had the final word. And this all while maintaining a smug, condescending, high-horse attitude towards anyone who doesn’t act the same way and believe the same things. And it’s pervasive, and often by people I love and respect, which has made me question whether it’s just me being sensitive, and it’s not actually a problem. But it’s infuriating, and I DO think it’s a problem. [Read more…] about A rant about science (alternately: All Hail Nuance and Skepticism)

What if you can’t love your body?

· · 1 Comment

Body image and self-love are hot topics in the blogosphere these days, and I don’t know how I feel about it.

Before I come off as the worst kind of person, let me just say that I’m thrilled people are learning to not be so hard on themselves for not being “perfect,” and for recognizing the beautiful things about themselves. I know I have my fair share of insecurities, and often I could do with a healthy dose of self-love.

But with almost every article I read in the continuously evolving collection of body image media, I’m left feeling not quite satisfied. Like the author has almost spoken to me, but was really speaking to a spot on the wall about a foot to the left. [Read more…] about What if you can’t love your body?

A word on raw meat, carnivory, and compassion towards animals

· · Leave a Comment

Note: this is one of my oldest posts, written when I was 19. My philosophy about food ethics has evolved considerably over the past decade – for instance, I no longer believe that the most “compassionate” diet is necessarily one devoid of any animal products, since the animals we’ve domesticated arguably have much to gain through their symbiotic relationship with humans – but in any case, most of what I wrote below still resonates deeply with me, and I’m quite proud of my past self to have realized many of these things at a relatively young age.

I’m sure you’ve all seen the recent story about this man who has eaten nothing but raw meat for the past 5 years. Chances are, you reacted in disgust, recoiling at the mere thought of eating the raw flesh of an animal (despite the fact that you have, in fact, eaten sushi on numerous occasions). I have to admit, some of the pictures definitely made my stomach turn a little bit.

I wasn’t surprised by the comments on the various news articles, calling him vile, disgusting, and mentally ill, and calling his diet a ‘weird food addiction.’ But I was surprised that even in Paleo circles, his story elicited a similarly negative reaction. I would’ve expected ancestrally-minded people to be a little more open-minded, and I don’t want to call out anyone specifically, but some of the comments were unbelievably ignorant.

I just want to bring a little perspective to the situation. The first complaint is that eating raw meat is ‘disgusting.’ I hope it’s pretty obvious to everyone that this reaction is only because we aren’t used to the idea. If you grew up in a completely vegan society, you would think that eating any meat at all is ‘disgusting,’ but because we’re so used to it, nobody bats an eye at the thought of eating a cooked chicken breast. As Americans we tend to find the idea of eating bugs revolting, even though billions of people around the world eat bugs regularly without a second thought. And if we weren’t used to consuming dairy, the thought of drinking the warm liquid from a squishy pink appendage dangerously close to the rear end of a cow would probably not be that appealing.

My nutrition studies: awesomeness and facepalms (plus cat pics)

skeptic cat
This is me every day in nutrition class. My face looks exactly like that. Just ask my nutrition TA.

This marks one month of my official nutrition studies at UNC, and it’s been surprisingly enjoyable! I absolutely feel like I’m in the right major, and I never had that feeling with Public Policy. (I do still have to be admitted to the School of Public Health though, so fingers crossed I get in!) There have been plenty of ‘facepalm’ moments, but I’ve also been impressed by some of the readings we’ve been assigned, and the overall scientific focus of the class.

Is it Possible to be Healthy on a Vegan Diet? [Part Two]

· · Leave a Comment

Note: this is one of my oldest posts, written when I was 19. I’m sure there are FAR better and more comprehensive summaries out there of the nutritional risks of a vegan diet, but this post (along with part one) do cover the high points, so I’ve left them up!

In part one, I discussed whether it’s possible to get enough vitamin D, calcium and vitamin K2 – three nutrients that are vital to bone health – on a vegan diet, without using supplements. We discovered that it is possible, but only if you get lots of sunlight, eat plenty of greens, properly prepare your nuts and seeds, and eat natto. In this post I’ll wrap it up by looking at iron, zinc, vitamin A, and vitamin B12. Then we can finally answer the question: Is it possible to be healthy on a vegan diet without the use of supplements?

Is it Possible to be Healthy on a Vegan Diet? [Part One]

· · 4 Comments

Note: this is one of my oldest posts, written when I was 19. I’m sure there are FAR better and more comprehensive summaries out there of the nutritional risks of a vegan diet, but this post (along with part two) do cover the high points, so I’ve left them up!

In my last post in this series on veganism, I looked at anthropological evidence to establish that as a species in our natural habitats, humans are omnivores, and we thrive on an omnivorous diet. But although we are still humans (most of us, anyways), we don’t quite live in our natural habitats anymore, so what applied to the natives that Weston Price studied doesn’t necessarily apply to us. In a modern-day setting with greater access to a variety of foods, can humans thrive on a vegan diet without needing to supplement? Is it biologically possible for humans to get what they need on a diet devoid of animal products?

In this two-part post, I’ll try to answer that question by looking at some of the nutrients that are hardest to come by on a vegan diet. In part one, we’ll look at three nutrients that are vital to bone health: vitamin D, calcium, and vitamin K2.

Are Humans Herbivores?

· · 7 Comments

Note: this is one of my oldest posts, written when I was 19. While this post is certainly not the “fresh take” on the natural diet of humans that I probably thought it was at the time, it still has solid information, so I decided to leave it up! 

This is part three of my series on veganism. Follow the links to read part one and part two!

One source of disagreement between vegans and meat eaters is the question of what humans are supposed to eat. Many vegans claim humans are herbivores, while meat-eaters assert that humans are omnivores. So what are we, anyways? Herbivores? Carnivores? Omnivores? Most of you probably know the answer to this already, but it doesn’t hurt to look at the evidence. To answer this question, it makes sense to start with what humans eat in their ‘natural habitat,’ when they’re completely undisturbed by modern civilization. As such, this post will look at what traditional hunter-gatherer cultures ate!

Plant-Based Diet or Plant-Based Diet?

Note: this is one of my oldest posts, written when I was 19. It’s pretty dumb, but since it’s part of a “series” and does no harm, I decided to leave it up. Enjoy 😉

This is part two of a series on vegan diets. If you haven’t read part one, you can read it here!

Before diving into the meat main part of this series, I think some clarification is necessary. Not all vegan diets are created equal, and the type of vegan diet in question is going to have a huge impact on every topic I want to discuss: nutrition, sustainability, anthropology, and ethics, to name a few. Other than the fact that all vegan diets are devoid of animal products, they can be as different and varied as the people who choose to eat them. As with anything, it’s a sliding scale, but for my purposes I’ve split them into three main categories. I’ve also tried to give them names that will make it easier for me to reference that particular type in the future (:

Veg*n is Not a Curse Word

· · 10 Comments

Note: this is one of my oldest posts, written when I was 19. Upon re-reading almost a decade later, I’m struck by my extreme naivety – but nevertheless, what I wrote back then does still resonate with me on a certain level. So, if for no other reason than to maintain a time capsule of my internet rants and raves, I decided to leave it up!

Yesterday, Alex Jamieson told the world that she is no longer a vegan. If you don’t know who she is and really don’t care, just bear with me for a minute. Alex is best known from the documentary Super Size Me, where her then-boyfriend Morgan Spurlock ate nothing but McDonalds for 30 days. Alex used a vegan approach to get Morgan’s health back on track after his 30 day McDiet, and she has since been a leading voice for health and nutrition in the vegan community. I would encourage you to read her post, but here’s the gist: Alex discovered that at this point in her life, her body needs some animal products to be healthy. Her post yesterday was the first time she’d publicly announced her decision to incorporate some animal products into her diet.
