Volume 8

Hello CSA Members,

We are now more than half way through our 2008 CSA season.  Thank you all for your partnership, as well as for your feed-back.

This continues to be a very trying year due to the extreme amount of torrential rains. Right now we have a beautiful planting of Italian Red Dandelion that we can’t get to because that part of the field is sitting in 6-8 inches of water.

We are very conscious of providing a decent variety mix for all of our tastes.  Please consider your share and what you perceived it would be, and then picture it, as it has really been.  The essence of CSA membership is shared bounty and/or loss, organic and sustainable as opposed to many pesticide/herbicide/fungicide applications with large amounts of chemical crop residue.

Our season is only successful as we receive communication from our members.  From 2 different sources this past week, both 2 year members, they spoke of being grateful for the variety and quality of what they received.  Because they have been multiple year members their observations are based on a wider range of experience.  That does not negate the feed-back from 1st year CSA members or invalidate by any means, the positive affirmation or criticism sent to us by any member. 

We also have a beautiful white corn for this week.  Interestingly enough, corn color has a regional bias that appears to us as quite comical.  Here in New England, only butter and sugar corn for most would suffice.  As you get to NY city, and south into New Jersey, yellow corn is all the rage, where as in Western Pa and Ohio white corn rules supreme.  I say, they are all great!  Try the white corn, you’ll love it!

From the Farm,

Ashley & Ethel

 

 

 

 

 

Unique Tomatoes Tops In Disease-fighting Antioxidants

. A new study,  suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use.

Researchers found that eating spaghetti covered in sauce made from these orange tomatoes, called Tangerine tomatoes, caused a noticeable boost in this form of lycopene in participants' blood.

“While red tomatoes contain far more lycopene than orange tomatoes, most of it is in a form that the body doesn't absorb well,” said Steven Schwartz, the study's lead author and a professor of food science and technology at Ohio State University.

“The people in the study actually consumed less lycopene when they ate sauce made from the orange tomatoes, but they absorbed far more lycopene than they would have if it had come from red tomatoes,” he said. “That's what is so dramatic about it.”

Lycopene belongs to a family of antioxidants called the carotenoids, which give certain fruits and vegetables their distinctive colors. Carotenoids are thought to have a number of health benefits, such as reducing the risk of developing cancer, cardiovascular disease and macular degeneration.

“The tomato is a wonderful biosynthetic factory for carotenoids, and scientists are working on ways to enhance the fruit's antioxidant content and composition,” Schwartz continued.

The findings appear in a recent issue of the Journal of Agricultural and Food Chemistry.

Lycopene is a carotenoid that contains a variety of related compounds called isomers. Isomers share the same chemical formula, yet differ in chemical structure. In the case of tomatoes, the different lycopene isomers play a part in determining the color of the fruit.

Several years ago, Schwartz and his colleagues discovered the abundance of several of these isomers, called cis- lycopenes, in human blood. But most of the tomatoes and tomato-based products we currently consume are rich in all-trans­-lycopene.

“We don't know why our bodies seem to transform lycopene into cis-isomers, or if some isomers are more beneficial than others,” Schwartz said.

The researchers don't know if tomatoes rich in cis-lycopene would provide greater health benefits to humans, but the study's results suggest that tomatoes can be used to increase both the intake and absorption of the health-beneficial compounds.

The researchers made spaghetti sauce from two tomato varieties – tangerine tomatoes, which get their name from their orange skin and are high in cis-lycopene, and a tomato variety chosen for its rich beta carotene content.

The tomatoes were grown at an Ohio State-affiliated agricultural research station in northwestern Ohio. Following harvest, both tomato varieties were immediately processed into canned tomato juice and concentrated. Italian seasoning was added for taste.

The 12 adults participating in the study ate two spaghetti test meals – one included sauce made from tangerine tomatoes, while the other featured sauce made from the tomatoes high in beta carotene. The participants were asked to avoid tomato and beta carotene-rich foods for 13 days before eating each test meal.

Researchers drew blood right before each participant ate and again every hour or two up to 10 hours after the meal. They analyzed the blood samples for lycopene and beta carotene content.

Lycopene absorption from the tangerine tomatoes was 2.5 times higher than that absorbed from the beta carotene-rich tomatoes and, Schwartz said, from typical red tomato varieties. Cis-lycopene levels spiked around five hours after eating the tangerine tomato sauce, and at this point during absorption the levels were some 200 times greater than those of trans-lycopene, which were nearly non-existent. While cis-lycopene is by far the most abundant isomer in these tomatoes, they do contain trace amounts of trans-lycopene.

The participants' bodies also readily absorbed beta carotene from the beta carotene-rich tomatoes.

“Right now, only carrots and sweet potatoes are a more readily available, richer source of beta carotene,” Schwartz said. “And this carotenoid is a major source of vitamin A for a large proportion of the world's population. Its deficiency is a serious health problem in many developing countries.

“Our study showed that a tomato can also increase beta carotene levels in the blood,” Schwartz said. While these special tomatoes were grown just for this study, the researchers have pre-commercial lines of both varieties available.

He conducted the study with Ohio State colleagues David Francis, an associate professor of horticulture and crop science; Steven Clinton, an associate professor of hematology and oncology and human nutrition; Nuray Unlu, a former postdoctoral researcher in food science; and Torsten Bohn, a former postdoctoral fellow in food science at Ohio State.

Funding for this work was provided by the Ohio Agricultural and Development Research Center in Wooster; the U.S. Department of Agriculture's IFAFS program; the National Center of Research Resources of the National Institutes of Health; and the National Cancer Institute.

Kale…

Health Benefits
Considered a "nonheading" cabbage because the central leaves don't form a ball, this verdant beauty grows in both warm and cool climates, and some types even grow in frost and snow. Common varieties include the tightly curled Scotch Vates and the red- to purple-veined Red Russian. The latter is sweet enough to eat raw, as is Lacinato, or "dinosaur," kale, an Italian heirloom variety.

Flavor aside, kale holds its own among fellow members of the Brassica family, including broccoli, brussel sprouts, and kohlrabi. The low-calorie green provides an excellent source of both vitamins A (as beta-carotene) and C, along with a decent amount of fiber.

Kale also delivers vitamin B6, which helps maintain healthy nervous and immune systems, as well as iron and calcium. In fact, our bodies can better absorb the calcium in kale than in spinach, as it has less oxalic acid, a substance that can disrupt the nutrient's absorption. Kale's vitamin K content, essential for proper blood clotting, far surpasses that of broccoli, spinach, and Swiss chard.

Perhaps most impressive, this versatile green contains especially high amounts of the carotenoids lutein and zeaxanthin, two powerful phytochemicals that may help safeguard the eyes from macular degeneration and cataracts.

Like many Brassicas, kale also delivers a hearty dose of sulforaphanes. These anticancer, antimicrobial compounds may suppress tumor growth by raising the body's levels of cancer-fighting enzymes.
