Got the Blues? Eat More Kale
Harvard researchers find a link between optimism and carotenoid levels in blood.

By Tom Philpott | Fri Jan. 25, 2013 9:55 AM PST

Humans have long turned to substances—from beer [1] to Prozac—to improve their outlook on life. But there's another possible remedy to the rigors of existence that doesn't get nearly as much attention: the green stuff that grows in the field, and I don't mean marijuana (though, hey, that might help, too). A new study (abstract [2]) from Harvard researchers found a strong association between adults' levels of optimism and the amount of carotenoid antioxidants in their blood. Carotenoids are found in richly colored green and orange vegetables, including [3] kale, sweet potatoes, carrots, and collard greens. The more servings of carotenoid-containing vegetables you eat, the results suggest, the brighter your outlook.

Of course, the researchers can't be sure that the association means a cause-and-effect relationship: It may just be that optimists are more likely to eat their veggies than pessimists, they emphasize. But unlike, say, Prozac, veggies' side effects are positive—for example, eating them improves life for the millions of beneficial microorganisms that live in our guts and keep us healthy [4].

If you're able to get your hands on some good product this weekend, here's a recipe for raw kale salad [5]that may or may not brighten your outlook, but will taste really good.

Try a little fresh squeezed lime or lemon; a sprinkling of sea salt and add a dash of cloves and ginger.

i had to check the dictionary for "kale"-never heard the word. I love it, actually eat quite often all sorts being a typical winter veggie. Not raw (love different salads) but I eat it cooked. Thx JL, interesting. ( "..that may or may not brighten your outlook"-hahaha)

For people who don't think they will like kale- if you cut it into thin strips and add it to some veggie chili or minestrone soup and cook it until soft, you will get plenty of nutrients but you will hardly even notice the kale!

When you read only the abstract, you have no way of knowing what methodology they used to make any conlusion. Abstracts don't tell you the controls and HOW they measured/determined against the control at various stages.

You really have to read the entire study/experiment to determine if their conclusion is sound and valid. The methodolgy used and sample size are absolutely critical for making this determination. Otherwise it could be completely bogus(as many unpublished studies are-supplement promotion).

A correlation between two groups is the absolute WEAKEST scientific analysis unless the sample size is extraordinarily large and over a long time frame. If the sample size of the group IS sufficiently large, there still MAY NOT be an exact conclusion drawn. Only an inferrence.

The sad part Research papers used to be free. All of them on the internet. Now, you have to either subscribe, or pay for them. The only free ones, the ones I read are Government funded-taxpayers paid for it, so its free to read to taxpayers.

But you really have to be educated enough to understand the language used in Experiment Design and Analysis.

It is not in common english terms.

Excellent explanation about some of the cautions and limits to pay attention to with research, especially pilot studies Heidi: You cannot currently send a star to Heidi because you have done so within the last week.
So glad you do if it's this healthy for us Carrie! You cannot currently send a star to Carrie because you have done so within the last week.

Cold-hardy and resilient, kale is an easy member of the cabbage family to grow. You can set out plants quite early in spring as long as you protect the young plants from severe cold winds with a cover. They will grow steadily for months until the weather gets too warm. You’ll get a second chance to plant kale in the fall, when cool weather brings out a wonderfully sweet, nutty flavor that is unique to these cold-natured plants. Fall is the best time to plant in areas where winter doesn’t dip below the teens, or in a cold frame farther north, because the leaves are sweeter when they mature in cooler weather.
Cheyenne: sounds like it could be grown in Norway.
You're welcome Lindsay and Ro

There probably was a time when eating any kind of vegetable like this would make me blue, but now I see the great health benefits and so neat to read about this. Thank you for bringing this study to our community.

I work on an organic CSA farm and have been eating the best kale lately... scraps gathered that were not "A" quality, but so tender and mild! I don't think it's the organic kale that is improving my mood though...RAVENS are Superbowl bound!!!
