Yogurt: 4 Things to Love (and 5 Things to Hate)

What's your problem, Crabby? Everyone Loves Yogurt!

Sure, I know yogurt is good for you, and you can get it in convenient little single-serving containers, and the taste is not unpleasant, but is anyone else starting to find yogurt just a little bit... annoying?

Okay, maybe it's just me. I do eat yogurt, even if it sometimes pisses me off. So I'll make sure to say some good things about it before I put on my crankypants and go all whiny and negative.

Four Reasons To Love Yogurt!

1. If you can do dairy, it's really healthy

If you can tolerate milk products, it's hard not to notice that plain lowfat or nonfat yogurt is absurdly good for you. And many people who are otherwise lactose intolerant seem to handle fermented dairy, like yogurt and kefir, better than they can tolerate regular milk.

So what's so impressive about the health benefits of yogurt?

Yogurt has lots of calcium and protein, and a bunch of other helpful nutrients like potassium and B vitamins. (Greek yogurt has a LOT of protein; but regular yogurt is better on calcium). And yogurt has something called lactoferrin, which is supposed to make it even better than regular milk at helping you build strong bones.

At the "World's Healthiest Foods" they've compiled a bunch of the studies showing yogurt's potential health benefits. And while the jury may still be out on some of these benefits (not enough studies yet), there are still enough encouraging reports so that you can feel pretty darn smug about eating it. Medical issues yogurt might be helpful for include the usual digestive stuff, but also arthritis, ulcers, cholesterol levels, colon cancer, and weight loss, as well as just generally boosting the immune system and increasing longevity.

One of coolest health aspects about yogurt? If you buy a good brand with lots of active cultures, then you get the magical benefits of probiotics. Probiotics are bacteria, but they're the "good" kind of bacteria. They won't go around giving you plague or eating up your flesh or otherwise behaving rudely like bad bacteria do.

Some of the health benefits of probiotics, even according to the fairly conservative Mayo Clinic folks are: treating diarrhea, yeast infections, urinary tract infections, irritable bowel syndrome; as well as reducing bladder cancer recurrence, preventing eczema and boosting the immune system.

(And Melting Mama notes that for folks who've had gastric bypass surgery, research indicates probiotics can help with quicker weight loss, as well as with avoiding Vitamin B deficiencies).

But all strains of probiotics are not created equal. If you want to know a lot more about probiotics, check out Probiotics--Love That Bug, where you can get the details about which strains are best for your particular health concern, whether it's irritable bowel or hay fever or ulcers or whatever.

2. It Tastes Good

We tend to think of yogurt as a sweet fruity treat, and it does make a nutritious substitute for more decadent indulgences like pudding or ice cream. But yogurt can also shine as part of a creamy condiment (like Kayln's "World's Best Tzatziki Sauce,") or as a main dish ingredient, like in Simply Recipe's Spicy Turkey Soup With Yogurt, Chickpeas and Mint or in The Perfect Pantry's Chicken Tikka Recipe.

3. It's Convenient

Well, it's not convenient if you want to get all fancy like the folks at Chocolate and Zucchini and you decide to make gourmet Frozen Sheep's Milk Yogurt. But yogurt is not exactly hard to find, and it comes in all sizes of containers, and you can get any flavor you can imagine. It's a quick way to get a snack with both carbs and protein, and it requires no preparation other than rounding up some sort of spoon. And even the spoon is optional if you're really hungry.

4. It's Relatively Cheap

Of course you can spend a fortune for some brands, particularly if you like to patronize trendy frozen yogurt emporiums in upscale neighborhoods. But your basic grocery store brand is usually pretty cheap. (My personal favorite brand, Fage, is on the pricey end, especially if I'm nowhere near a Trader Joe's, but I'm awfully fond of it).

However, the cool thing about yogurt is that you can also make your own, and people swear it's not even hard. There's A Year of Slow Cooking's crockpot yogurt recipe, and Charlotte at the The Great Fitness Experiment makes her own with no special equipment at all.

So, with all these wonderful virtues, what is it about yogurt that gets me cranky? Well, enough weird things that I had to resort to making up my own words.

Five Irritating Things About Yogurt

1. Dessertification

Have you perused the yogurt section at the grocery store aisle lately? You can barely find any plain yogurt because there are 7,000 "flavors" of yogurt, all passing themselves off gourmet desserts. Even regular fruit flavors aren't "desserty" enough for most buyers; who wants lemon or lime yogurt when you could be eating "Lemon Cheesecake" or "Key Lime Pie?"

And it's not just the absurd proliferation of exotic flavors, it's that most of the stuff tastes unnecessarily oversweetened. Why do they need to add SO MUCH sugar and/or artificial sweeteners? It seems impractical to use up so much of your daily allotment on one little serving of dairy product, when you might as well be eating a big fat slice of chocolate cake. In my mind, yogurt ceases to be a health food when it's got more sugar than an ice cream sundae or is pumped up with enough aspartame to kill several large lab rats.

I've learned to just buy plain yogurt and flavor it myself.

2. Pharmification

While live active cultures are a good thing, the relentless health promotion around yogurt as "medicine" is getting irritating. Especially when big corporate yogurts start throwing in "healthy" additives, like extra vitamins and fiber, that don't occur in there naturally.

3. Feminization

My all-time favorite Sarah Haskins video explores this weird phenomenon: what's with the single-sex marketing of yogurt?

Are guys simply not allowed to eat yogurt? Are women required to eat yogurt? Have you ever seen a bunch of men in a commercial talking about yogurt?

Hmm... Maybe it's some sort of a conspiracy. Because doesn't it seem suspicious that it's nearly the same thing with Yoga? It's also marketed as "healthy" and targeted strongly at women. Yoga and Yogurt: For Women Only! Oh wait, but Yogi Bear was a boy, and not known for healthy habits, so I'm not sure the conspiracy is very well organized yet.

4. Packagification

Long ago, back in the olden days, you used to have a couple of sizes of yogurt. There was the Big-Ass economy sized yogurt, if you were willing to eat a lot of the same flavor, or a smaller size if you wanted variety. But I swear the small size was more like 10 or 12 ounces. Then that went down to 8, then many yogurts shrunk even further to 6, and now you see these itty bitty containers that have maybe two tablespoons of yogurt in them, they come welded to other itty bitty micro-yogurt containers. So you still have to spend a bunch of money, but instead of getting a whole massive amount of yogurt you get a little bit of yogurt and a whole heck of a lot of packaging.

Progress... ain't it great?

5. Proliferation

Yogurt is immensely popular, and so the major brands are taking more and more space in the coveted refrigerator section of your grocery store. And because it's so important to stock all those pre-sweetened yogurt varieties the public demands, your average chain spares little room for other healthy products that could be sitting there. The more natural yogurts made by the little guys? The non-dairy options? You often have to go to a health food or other specialty store to find them.

My own personal grudge: I like kefir. It's another cultured dairy product that tastes a lot like liquid yogurt, and has even more probiotic strains in it. From what I can tell, it might be even more awesome for you than yogurt is, but it's not as popular so there are even fewer studies on it. I love to add it to smoothies. Yet the chain grocery store nearest me doesn't stock kefir because they apparently need room for each and every one of those 7,000 yogurt flavors. (I'm thinking of trying to round up some kefir grains and start making my own. It's supposed to be fairly easy. However, the problem is the hippie-era distribution system, which seems to rely on knowing someone who knows someone who has extra. But enough about my Kefir Madness.)

So do you eat yogurt? Do you love everything about it or do you have any gripes?

Obesity, Probiotics, and Pregnancy

Photo credit: mahalie


Good news for pregnant yogurt-lovers! Scientists in Finland looked into the effects of probiotic consumption during pregnancy. And they found that probiotics helped reduce post-pregnancy obesity levels.

Probiotics, as you may recall, are those "good" bugs that live in cultured foods like yogurt and kefir. (As opposed to the "bad" bugs you get when you drop your food on the kitchen floor and, if no-one's looking, decide to invoke the "five second rule" and eat it anyway.)


Nachos: Sadly, not a great candidate for the 5 second rule.
Unless you're really, really, hungry.

So, you might wonder, what if you're not pregnant--can you eat a bunch of yogurt or takes some capsules and lose some quick belly fat?


Well, I wondered that too. And I am still wondering that. There doesn't seem to be a whole lot of research yet. But in the meantime, there are lots of reasons you might benefit from eating probiotics anyway.


But First, The Pregnancy Study

The researchers assigned 256 pregnant women randomly into one of three groups. The first group (we'll call it the "Lucky" group) got capsules with lactobacillus and bifidobacterium as well as dietary counseling. The second group (the "Dummies") got dietary counseling and placebo "dummy" pills with no good bugs in them. The third group (the "Loser" group) got bupkus--no dietary counseling and no real capsules, just the placebos.

The women took the capsules starting in their first trimester of pregnancy, and continued until "the women stopped exclusive breastfeeding, after up to six months." (Presumably they meant after the baby stopped exclusive breastfeeding--unless there are some very odd diets new moms are trying out these days).

The researchers were particular interested in "central obesity," which is worse for your health than the big-butt kind of obesity. Central obesity was defined as "a body mass index (BMI) of 30 or more or a waist circumference over 80 centimetres." (Or for those of us who live in the United States where we're too damn lazy to just suck it up and switch to the metric system like the rest of the world--80 centimetres is about 31 and a half inches.)

(Picky, boring research side note: Here's where I thought the methodology got kinda funky. How accurate are stomach measurements during pregnancy at capturing actual fat gain? Probably not very. Because one woman might be carrying twin sumo wrestlers, while another woman may be pregnant with a tiny future ballerina. So the researchers didn't gather initial waist measurements, even though central obesity is what they were mostly interested in. Apparently they couldn't go back in time and get them pre-pregnancy. Instead it looks like they just used post-partum averages to compare the groups, which would mean a lot of noise in the data).

Anyway, turns out only 25 per cent of the women who had been given the probiotics as well as diet advice fell into the "central obesity" category, compared to 43 per cent of the women who got dietary counseling alone, and 40 per cent of the women who got neither diet advice nor probiotics. The average body fat differences were less dramatic, but I'm assuming they were statistically significant: 28 per cent, 29 per cent, and 30 per cent respectively.

Blah blah blah. You lost me at 256 pregnant women. Get to the point, willya?


Oh, hi there! Yeah, so it seems like there's at least something interesting going on with probiotics perhaps helping fight post-pregnancy obesity. Keep an eye out for further studies.

(And does anyone else find it interesting how little impact dietary counseling had compared to the probiotic pills? Sounds like either most women pretty much blew off the advice, or that the standard nutritional advice doesn't do squat towards preventing obesity.)


Why Did They Just Study Pregant Women?


One might wonder why the researchers chose to study the probiotic/obesity connection in pregnant women since pregnant women are so hard to measure and all?

Well, it turns out one of the reasons was that the researchers wanted to keep following the women and their babies to see whether the pre-natal probiotics will influence the babies' health.

“Particularly during pregnancy, the impacts of obesity can be immense, with the effects seen both in the mother and the child. Bacteria are passed from mother to child through the birth canal, as well as through breast milk, and research indicates that early nutrition may influence the risk of obesity later in life. There is growing evidence that this approach might open a new angle on the fight against obesity, either through prevention or treatment.”

Dang it. Cute babies... they win every time!




So Should We All Start Eating Yogurt For Weight Management?

Alas, I couldn't find much other non-pregnancy research on probiotics fighting obesity, other than the "scientists are looking in to it" kind of thing. But it's possible that my hours and hours of scholarly research 3 minutes on google might have missed something useful.

However, you can bet if it turns out there's any connection, scientists and product marketers will be all over this one.


But There Are Other Great Reasons to Get "Cultured" Too!

Mayo Clinic has a brief run-down on some of the medical benefits of probiotics. Like they can:

  • Treat diarrhea, especially the kind you get after taking antibiotics
  • Prevent and treat vaginal yeast infections and urinary tract infections
  • Treat irritable bowel syndrome (IBS)
  • Reduce bladder cancer recurrence
  • Shorten the duration of intestinal infections
  • Prevent and treat inflammation following colon surgery (pouchitis)
  • Prevent eczema in children
  • Aid in general health

Which Bugs for Which Problems?

While the supplements in the pregnancy study were the commonly seen lactobacillus and bifidobacterium, there are lots of other different probiotics strains out there. Some work better than others for specific medical conditions.

For a helpful guide to probiotics you may want to check out Love That Bug (Old-timer Cranky Fitness readers may recognize that as that the site of our friend Dawn Rotarangi of The Flightless Writer). There are lots of specifics there, whether you're dealing with hay fever, IBS, "women' stuff," or a bunch of other medical issues.

And speaking of "women's stuff"...


Why Women MUST Eat Yogurt!

I probably ran this video already, since it's a year old and I thought it was hilarious when I first saw it. Anyway, here it is again:





So do you folks make an effort to get some good bugs in your diet? Would you eat more if it turned out it discouraged extra fat around your waist?
