How much nutritional value is in carrots and other produce grown today?

Dear EarthTalk: What’s the nutritional difference between the carrot I ate in 1970 and one I eat today? I’ve heard that that there’s very little nutrition left. Is that true?Esther G.Newark, N.J.It would be overkill to say that the carrot you eat today has very little nutrition in it — especially compared to some of the other less healthy foods you likely also eat — but it is true that fruits and vegetables grown decades ago were much richer in vitamins and minerals than the varieties most of us get today. The main culprit in this disturbing nutritional trend is soil depletion: Modern intensive agricultural methods have stripped increasing amounts of nutrients from the soil in which the food we eat grows. Sadly, each successive generation of fast-growing, pest-resistant carrot is truly less good for you than the one before.A landmark study on the topic by Donald Davis and his team of researchers from the University of Texas (UT) at Austin’s Department of Chemistry and Biochemistry was published in December 2004 in the Journal of the American College of Nutrition. They studied U.S. Department of Agriculture nutritional data from both 1950 and 1999 for 43 different vegetables and fruits, finding “reliable declines” in the amount of protein, calcium, phosphorus, iron, riboflavin (vitamin B-2) and vitamin C over the past half-century. Davis and his colleagues chalk up this declining nutritional content to the preponderance of agricultural practices designed to improve traits (size, growth rate, pest resistance) other than nutrition.“Efforts to breed new varieties of crops that provide greater yield, pest resistance and climate adaptability have allowed crops to grow bigger and more rapidly,” reported Davis, “but their ability to manufacture or uptake nutrients has not kept pace with their rapid growth.” There have likely been declines in other nutrients, too, he said, such as magnesium, zinc and vitamins B-6 and E, but they were not studied in 1950 and more research is needed to find out how much less we are getting of these key vitamins and minerals.The Organic Consumers Association cites several other studies with similar findings: A Kushi Institute analysis of nutrient data from 1975 to 1997 found that average calcium levels in 12 fresh vegetables dropped 27 percent; iron levels 37 percent; vitamin A levels 21 percent and vitamin C levels 30 percent. A similar study of British nutrient data from 1930 to 1980, published in the British Food Journal, found that in 20 vegetables the average calcium content had declined 19 percent; iron 22 percent; and potassium 14 percent. Yet another study concluded that one would have to eat eight oranges today to derive the same amount of Vitamin A as our grandparents would have gotten from one.What can be done? The key to healthier produce is healthier soil. Alternating fields between growing seasons to give land time to restore would be one important step. Also, foregoing pesticides and fertilizers in favor of organic growing methods is good for the soil, the produce and its consumers. Those who want to get the most nutritious fruits and vegetables should buy regularly from local organic farmers.UT’s Davis warns that just because fruits and vegetables aren’t as healthy as they used to be doesn’t mean we should avoid them. “Vegetables are extraordinarily rich in nutrients and beneficial phytochemicals,” he reported. “They are still there, and vegetables and fruits are our best sources for these.”

A life reshaped by clay in “Matin”

On Monday, Oct. 26, a group of students, teachers and local residents gathered at the Hotchkiss School in Lakeville for a screening of the new short documentary “Matin.” The film tells the story of Matin Malikzada, a seventh-generation Afghani potter making a new life in New Milford, Connecticut. The film was made by local filmmaker Yonah Sadeh, creator of the Video Wall at the David M. Hunt Library, and Berkshires-based potter Hannah Wheeler, who were both present for the screening, along with Malikzada himself.

As a member of the seventh generation of his family to master the art of pottery, Malikzada had done things the way his family had for over a century. Istalif, the village where his family has lived for generations, was known throughout Afghanistan for its pottery, with wares sent across the country for use as everyday cups, bowls, plates and other vessels. The pottery-making families of Istalif gathered clay from the same mountain, about 30 to 45 minutes away by donkey. Every July, they would head north toward the Uzbekistan border to gather ishkar, a plant they processed by hand to make their signature glazes.

When Meg Sher came to Falls Village in 2006 from Old Lyme, Connecticut, where she grew up, she never imagined she’d someday be the executive director of the David M. Hunt Library.

Although, in hindsight, perhaps it makes sense.

Crescendo’s 23rd season speaks to the heart and mind

Christine Gevert, founding artistic director of Crescendo, conducts the audience at a performance.

Steve Potter

For Christine Gevert, founding artistic director of Crescendo, music from centuries past is anything but a relic. It is a living, breathing art form, full of drama, emotional complexity and, occasionally, surprises. As the regional choral and period-instrument ensemble launches its 23rd season, Gevert is once again bringing forgotten masterpieces into the present.

“Early Music has been my lifelong passion and the focus of my specialization in Europe and South America,” Gevert said. “Bringing this repertoire to our audiences in a nuanced way that does justice to its incredible depth, intensity, and beauty is deeply important to me.”

Shinbone Alley brings spooky songs to Spencertown

Seeing isn’t always believing. Sometimes it’s the lack of a defined picture that can be the most compelling. And when Alex Harvey of Shinbone Alley sings his supernaturally charged sea shanties and street ballads, the unseen will be downright scary. On Oct. 30, the historically inclined storyteller and performer will create a spooky evening of forbidden tales and yarns through a carefully chosen series of songs at Spencertown Academy of Arts.

The repertoire for the performance is a bit fraught. Over the years, Shinbone Alley has explored the world of folklore through music. Though the group usually features two musicians, Harvey, a multi-instrumentalist and singer, will be performing solo. That is, of course, unless you include the spirits.
