An average Jane on health and nutrition

GMO (genetically modified organisms) is a term we’re hearing a lot about lately. Consumer advocate groups are pushing for mandatory GMO labeling, while companies like Monsanto fight against it. As of right now, Maine and Connecticut have passed regulations regarding labeling, but they hinge on other states following suit. Connecticut’s, for example, only goes into effect if at least two additional states also adopt such policies, and at least one of those states must be a neighboring state. (So, Massachusetts, Rhode Island, or New York.) Connecticut is a little state, and I imagine the thought behind that is safety in numbers. It’s harder for Monsanto (or anyone) to apply pressure to an entire region than it is to a single state, though that hasn’t stopped them from threatening lawsuits.

Advocates and opponents of GMOs seem to be in agreement (at least for the moment) that genetically modified crops [probably] aren’t harmful to our health. Why, then, the opposition? Many argue it’s simply a case of transparency: that people deserve to know where their food comes from/how it has been grown.

For the purposes of the article I’m going to discuss, there are two types of genetically modified crops. There are crops that are modified to be resistant to pesticides or herbicides, meaning farmers can apply the chemicals that will kill weeds and bugs but not damage the crop; and there are crops that themselves exude a pesticide/herbicide. The goal in both cases is to defeat weeds and bugs, keeping the crops free from such pests. And it’s worked, for awhile.

But if the flu virus has taught us anything, it’s that nature changes. A lot. And sometimes rapidly. Enter “superpests.”

That’s right. Weeds and bugs are adapting to the pesticides and herbicides, and finding ways to feast on the crops anyway. They’re growing stronger.

Okay, maybe not stronger, but certainly immune-r.

So, what to do? Apply more pesticide. 10 times more, in fact, if they’re using the popular Monsanto herbicide Roundup on corn/soy/cotton. (From Grist, link below.) Additionally, even stronger chemicals are awaiting approval, though delayed over concerns for water contamination, higher levels of chemical residue in food, etc.

Is there any other option? Perhaps.. from the same article:

“But there’s an alternative to better living through chemistry: Farmers can simply stop planting corn year after year and learn to love oats and alfalfa. As one crop consultant told NPR, the simplest, cheapest, safest solution is just to switch to another crop for a bit. Rotating crops, i.e. growing different crops in sequence on the same plot of land, is an old technique for foiling pests. Very often, a bug that eats one crop won’t eat a different one.”

So, there’s the option to return to a more diverse method of farming. Outsmart the bugs and weeds simply by making their food source unavailable some years. Will it affect profitability, etc? “Recent research into crop rotations indicated that farmers won’t necessarily lose money since they’ll be spending a lot less on high-priced GMO seeds, chemicals, and even fertilizer.”


Well that’s great!  
“Even the USDA gets this. The agency has started to promote the adoption of what it calls “multi-cropping” for improved pest management and climate resilience. The problem is that the agency is also encouraging biotech companies to keep the herbicide-tolerant seeds coming.”

Oh. Well that’s less great.

With Monsanto execs having recently won the World Food Prize, I doubt we’ll see major shifts away from GMO and increased herb-/pesticides in favor of crop rotation soon, but maybe in the future.

I think the thing that gets me most is that we’re like “nature keeps adapting and finding better ways to beat our chemicals.. so let’s make STRONGER CHEMICALS!!” not “hmm.. maybe this system isn’t working, and we need a new (or reverting to an older) system, instead of tinkering with what isn’t working and bandaging it unendingly.”

Until then, fortunately I live somewhere with lots of small local farms and farmer’s markets. Not everyone is so lucky, and we shouldn’t be encouraging the introduction of yet more chemicals and altered food, especially when we’re not sure of longterm effects.


So, first things first, I’m extremely excited to say that part of why I’ve been a bit quiet here the last few weeks is that I’ve been interviewing for and securing a new job! As of next week, I will be a writer for a public health communication firm. I’m stoked for the new challenge in a field that I’ve been wanting to get in to, and for a great company whose goals align well with mine. It’s all about clear, accessible communication on a variety of health, medicine, and wellness topics. Writing is my specialty, health and wellness my interest, so this is a thrilling opportunity for me to positively influence public health in my own small ways.

In addition to the interesting, challenging projects, I’m excited for the company culture. They are open to workplace wellness initiatives (like group stretch breaks! Warms my yoga-loving, anti-computer-hunching heart) and I’ll be close enough to bike to work again sometimes, something I’ve sorely missed doing. It’s really energizing to start the day off by hitting the bike. The movement, the fresh air. A great way to wake up. (And, by the time I get home, I’ve already done a good workout for the day, without taking too much extra time!)

So yeah. Really happy about this.

But, I signed in with the intention of making a ‘real’ post.. SUPERWEEDS. Stay tuned.

IDoF: the documentary

Just found out that Michael Pollan’s In Defense of Food is the basis for a documentary of the same name, to be aired on PBS sometime next year.


Quite interested to see it. If you haven’t read the book, I highly recommend it.

Every year in a nearby city, there’s a 5k in December called the Hot Chocolate Run. This year, my good friend Ashley wants me to run it with her.

I’ve never done a 5k, and I’m the kind of person who often laments that I don’t like running for the sake of running. I’m really more of a cyclist. Running for soccer, sure. Running to escape serial killers, yes. Running.. because..running? It’s just never been my thing. But perhaps that’s been because I haven’t really been in “runner” shape. Where I can bike 35+ miles, for some reason running 1 is a challenge. Perhaps trying to do too much too fast, or whatnot. But Ashley would like some company. The conversation was short, and went like this:

Ashley: You should do the hot chocolate 5k with me this year.

Me: I dunno… running in December sounds like it would suck. Like I would try to breathe and the air would be so cold that my lungs feel like they’re on fire and miserable.

Ashley: Yup, that happens.


Ashley: So, what d’ya think?!

The run is a bit over 2 months away, which is, conveniently, about the amount of time required in the infamous Couch-to-5k running plan. So, I guess I’m tentatively committing to this. In the hopes of staying motivated (and perhaps introducing some accountability) I’m making this post. I have also thrown an invite out to two of my runner cousins who both go to college nearby. The more the merrier, right?

And hot chocolate at the end.



Have you run a 5k? What do I need to know for my first one? What do you wish someone had told you when you got into running?

Nutrition class, no

Turns out, “intro to nutrition” was just a bit too intro for where I am at this point in my nutritional understanding. I dropped the class today.

I was a little bummed about that, because I’d been looking forward to doing something more nutritionally-focused in an academic way, and then I had a better idea. Look into those open course MIT things.

Has anyone ever done them? Apparently, there are a bunch of classes that MIT posts lecture notes/videos, reading assignments, homework topics, etc. for, and if you want to do the work, go for it. It’s free, it’s not really being “taught” to you, but it puts the tools in place, along with a full, complete professor-delineated curriculum. Which, as someone who is interested in things, but can get lost in the sheer amount of information available, I very much appreciate.

There’s a *whole class* on cholesterol, and its role in our cells. Call me a dork all you want, that sounds fascinating.

What I’m likely to do is go through the writing about food class first. Set up a recurring time each week to read through the lecture notes, do the homework on a regular basis, complete the four required essays. Treat it like an in-person class. Just, not.. in person.

We’ll see how that goes. If nothing else, academic writing. Learning new things. Using my mind a little more than is currently sometimes required by my work-life circumstances. (Although I have to say, I have some truly incredible people in my life, and one in particular, who challenge me in the best intellectual ways constantly. Complex, interesting debates on a range of topics. Really gets those synapses firing.)

There are some other really interesting sounding classes.. history of the immune system, synthesizing protein. If anyone’s interested, I’d love a study-buddy. 🙂

Whatdya say, we’ll ‘take’ the class together!

food health ratings and NuVal

Recently, a discussion came up with a friend about the concept of health ratings on food. It was suggested that, in the future, supermarket receipts could include a health rating for the food we purchase.
I bristled a bit, because such a system would depend on being able to say, with reasonable correctness, what is “healthy.” Yes, we could say “carrot” is healthier than “potato chip” but do we know enough about nutrition to craft such a scale beyond broad distinctions? Could we say with certainty whether an apple should have a higher score than an orange, or that low-fat cheese is absolutely better for you than full-fat?
Of course, there already are rating systems in place, and my friend’s point was that nutrition science hasn’t stopped just because we’ve created them. We continue to experiment and learn, and, as necessary, update such rating systems. The fact that we don’t know everything doesn’t mean that we shouldn’t publish the information that we do know.
Here in the Northeast, there’s a grocery chain that uses the NuVal system. Short for “nutritional value,” it was developed by a panel of scientists and academics from a variety of discplines, including biochemistry, endocrinology, and more. The system ranks items in the grocery store on a scale of 1 – 100, with 1 being the least healthy and 100 the most healthy. The score is displayed on the shelf label. But what exactly is this score?

The team worked for two years, referring to the most comprehensive science available, to develop the Overall Nutritional Quality Index (ONQI™), a patent-pending algorithm which converts complex nutritional information into a single, easy-to-use score. The ONQI™ algorithm is now the scientific engine behind the NuVal System, and together they are helping people make faster, easier, and better decisions about the foods they buy.

That is to say, the NuVal system seeks to apply a mathematical formula to food, in order to provide a quick gauge of healthfulness at the point of purchase and, hopefully, encourage better food choices. The score is the result of that formula. The effort should be lauded, as the translation of complex information into easily understandable terms is of the utmost importance when referring to food, medicine, and health. However, I have reservations about the actual process of this particular system.
At the very basest level, the scale works by taking a score of “good” nutrients (among them such things as fiber, potassium, calcium omega-3s, iron, vitamins, etc.) to use as numerator, and a score of “bad” nutrients (saturated fat, trans fat, cholesterol, sugar, sodium) as a denominator, dividing to achieve the score. While the nutrients are weighted differently, potential pitfalls exist nevertheless. One question springs to mind immediately: Does the scale differentiate between naturally occurring sugar and added sugar?
Presently on food labels, there is no requirement to state the amount of natural sugar and the amount of added sugar as separate numbers. In the case of fruits, this is not a problem (at least, I hope we’re not getting added sugar in our apples…) but with something like dairy, it’s a much bigger issue. A container of yogurt that has no added sugar can still have several grams of it naturally occurring, and thus cannot be directly compared to a yogurt that has sugar added. My assumption is that it is not distinguished for the purposes of the NuVal scale or the “bad” denominator, and sugar is sugar, lowering the score whether it’s an apple or a piece of candy.
And therein lies the problem. Leaving aside my hesitance to label foods and their components as categorically ‘good’ or ‘bad,’ such as the scale seeks to do, we’re once again trying to reduce foods to delivery systems for these nutrients. We’re once again ignoring the possible synergistic ability of the nutrients to create, as Michael Pollan might say, a food that is more than the sum of its nutrient parts. A scale such as NuVal tells us that nutrients cannot exist in any type of grey area. They are either good for us, or bad for us. As we’ve learned in recent history, this is not always the case. We’ve uncovered distinctions in types of cholesterol, and no longer can speak of it as solely a “bad” thing. We’ve learned after years of demonizing fat that it, too, has its place as a positive nutrient for the human body, depending on the type of fat. We’re beginning to understand that food and the food needs of the human body are far more complex than simply saying X is bad and Y is good.
For NuVal, the most interesting example comes in the case of fish. The concerns about mercury in our diets are acknowledged by the scale’s creators, but are subsequently ignored due to the belief that fish have more benefit than risk:
Regarding mercury content in certain seafood, the scientific literature shows that the net effect of eating fish regularly is a health benefit, in spite of the associated toxins. Consequently, the NuVal Scores provide reliable guidance to the role fish should play in the diet.
The NuVal score does not take into account “toxins” in food, stating that there is currently no standard for measuring toxins. While this is true, the fact that the creators specifically acknowledge that toxins cannot be gauged and are therefore ignored suggests to me a flaw in trying to create this scale in the first place. While fish are widely considered healthy, to not include their most detrimental factor in a scale measuring healthfulness artificially inflates their health score. Ignoring a known facet related to healthfulness hinders the integrity of attempting to use a mathematical formula, which should be immune to the whims of the people using it. If we are ignoring the mercury in fish in order to not lower its NuVal score, can we not also choose to ignore the cholesterol in egg yolks, because that’s where the vitamins are? Can we not ignore the sugar in fruit? The saturated fat in peanut butter? Perhaps the answer is not to ignore the toxins, but to first seek to create a standard for measuring them that could then be included in the score calculation.
This and many other issues suggest that food science still has a lot to learn. Science is never-ending, and that’s a good thing. All forward motion counts, and, as my friend pointed out, we should be sharing the most up-to-date breakthroughs. But we could perhaps find a way to impart the scientific information we have at the time more clearly, with greater weight given to accuracy of the science and the journalism than to snappy headlines that overpromise health benefits.
My friend asked, pragmatically, what I suggest, then, for a population that needs the information, but likely isn’t going to take the time to do a lot of in-depth analysis. A good question. The problem is that different things will work well for different people and their bodies. So really, the answer is, “Do what works for you.” But it’s hard to sell that, journalistically, when we crave specific advice. The answer, then, perhaps, is to make the information we have clear and understandable in a way that engages the reader and encourages continued interaction with health materials. If science is ongoing, so, too, must be the reading and understanding of that science by as many people as possible.
One day, maybe we’ll get to the point scientifically that we can say we’ve discovered the optimal diet, with the optimal amount of x, y, z nutrients. But I think we’re far away from that. Until we’re closer, I’m hesitant to rely on any type of scale that quantifies food by good/bad nutrients. I’m hesitant to rely on a scale that tells me skim milk is healthier than whole, because of that demonic fat.
If we must create a scale, perhaps we could consider one that ranks the amount of processing of a particular food: No processing for fresh fruits/veggies, some processing for flours, rices, and items with small lists of ingredients, all the way up to “there’s not really any actual food in here.” (Looking at you, Cheez-Wiz.)
I’m guessing we’re not going to see that any time soon, though. So for now, for me, it’s common sense. It’s fresh fruits and veggies in abundance and foods that are minimally processed. It’s cooking. NuVal may provide a guide, but for me, it’s a guide taken with a grain of salt.
Do you agree, disagree? Is there a rating system for foods at your grocery store and does it have any effect on your purchasing decisions when you shop?

back from vacation

I’ve been quiet for a little while because I’ve been spending time with family and the water and the great outdoors up in New Hampshire.

So peaceful.



Vacation is time for board games and grilling and sleeping in. And for fun activities. The cottage we stayed at had a pedal boat, canoe, and kayak for our use. I got in some good kayaking, and, here, taking out the canoe with my mom in the early morning.



It’s not often that I get to take multi-day vacations, and this was very welcome. It’s unfortunate that the way our society is set up, vacations, even just staying home and doing something you enjoy, aren’t really something we encourage. But they are so so necessary. I feel much more refreshed. Ready to tackle work, to tackle life.

Vacation was pretty late into August, and its conclusion really felt like winding down the summer. September 1st is always the end of summer in my head, so coupling it with vacation ending so close to that really makes me feel like this season has come to an end.

But, in other exciting news, next week I start an intro nutrition class, as potential preparation for my Master’s degree. I’m looking forward to getting more formal education on nutrition, though I rather expect to find some interesting dichotomies between the current accepted “nutrition think” and the backlash to Big Food, etc.

I also just miss academia. So that will be fun.

I have a post partly finished about Mark Bittmann’s TED talk on “What’s Wrong With the Food We Eat” but it needs a little more honing. Look for it soon! 🙂

Happy end of summer, everyone.
