Aiming to energize the seed industry cluster surrounding UC Davis, Seed Central, an initiative of the Seed Biotechnology Center at UC Davis and SeedQuest, recently highlighted postharvest handling and food safety at their monthly forum. Recordings of invited guest speakers, Marita Cantwell, Trevor Suslow and Roberta Cook, UC Cooperative Extension specialists with expertise in post harvest science, show the passion they feel for their respective subjects and why we're fortunate to have them on our team. Cantwell and Suslow are in the UC Davis Department of Plant Sciences; Cook is in the UC Davis Department of Agricultural and Resource Economics.
Cantwell, a postharvest physiologist, specializes in handling and storage of intact and fresh-cut vegetables. In her talk, she describes the Postharvest Technology Center itself and gives an overview of the handling challenges of many vegetable varieties.
A plant pathologist, Suslow’s program centers on studying the effects of microflora on the postharvest quality of perishable produce. With much attention to current food safety a priority, Suslow’s produce safety overview and specific case examples help us all (ahem) digest this hot topic.
Cook, an agricultural economist, focuses on fresh produce marketing and food distribution. This presentation centers on North American vegetable markets. Even if you’re not a grower, shipper or retailer, Cook's description of trends in the produce industry are fascinating — we all eat fruits and vegetables every day. She talks about things we might not ever think about.
What will be the new food frontier? An article in the Wall Street Journal with the headline “Next Stop for Food Fanatics: Africa” predicts adventurous American palates may soon be craving sub-Saharan cuisines.
Have you heard of these?
- Nakati (Solanum macrocarpon, S. aethiopicum) Also called African eggplant, some types of nakati are eaten for their leafy greens, while others are eaten for their fruit (which can look like a tomato or eggplant).
- Cowpea leaves (Vigna unguiculata) This plant produces black-eyed peas, but the greens of the plant can also be eaten as a vegetable.
- Bbuga (Amaranthus Gracecizans) You might know this plant by its common American name: pigweed.
- Doodo (Amaranthus Dubius) Like bbuga, this type of amaranth is eaten for its leaves in many parts of Africa. In North and South America, varieties of amaranth are usually used as a grain.
- Jjobyo (Gynandropsis Gynandra, Cleome gynandra) Also called spider plant.
Many of these indigenous vegetables are rich in micronutrients such as iron, vitamin A and vitamin B. When it comes to alleviating malnutrition in developing countries of eastern Africa, indigenous vegetables offer workable solutions because they are not only nutritious, but also familiar to the region’s eaters and farmers.
Recently U.S. researchers have been working with indigenous crops like these in east African countries — with funding and support from the Horticulture Collaborative Research Support Program (Horticulture CRSP), led by Beth Mitcham at UC Davis with funding from USAID. In Kenya, Tanzania and Zambia, Stephen Weller of Purdue University is leading a Horticulture CRSP research project on production practices, seed resources, postharvest handling, marketing and nutrition of varieties of amaranth, spider plant and African nightshade.
Take a look at this short video for a little more background:
Just as bok choy, an Asian vegetable, has become familiar to many American households, perhaps one day you’ll find nakati or another African leafy vegetable on your plate.
In the meantime, researchers with Horticulture CRSP are working to get more African leafy vegetables into the research agendas, fields, markets and plates of our counterparts in eastern Africa.

Only in California could arid land be converted into the nation’s salad bowl.
In the late 1800s, University of California researchers discovered how to remove salts from the soils of the Central Valley, turning it into one of the most productive agricultural regions.
UC researchers continue to play a key role in agriculture today, keeping California the nation’s leading agricultural state, from dairies in Tulare to nut farms in Newberry Springs.
A new brochure highlights the breadth of UC Agriculture and Natural Resources’ impact. UC guidelines have helped farmers boost broccoli production. UC scientists have developed sweet-tasting citrus and strawberries to meet consumer demands. UC certifies more than 95 percent of wine grapevines grown in the state, providing a reliable supply of high-quality vines for California’s multibillion-dollar wine industry. Whether it’s managing invasive pests, promoting nutrition or sustaining small farmers, ANR serves California’s communities with a focus on advising, educating and searching for solutions.

We all know that eating dark leafy greens is good for us, right? So that’s why for lunch lately I’ve been on a health kick to eat a big bowl of dark leafy greens topped with a lean protein source. I have, however, been subject to some good-natured ribbing around my office regarding my lunch selections. So I decided to research my lunch ingredients, and why I, as well as my inquisitive co-workers, already know it’s something of a power lunch, in the most nutritious of ways. First, the base of my lunch: a mix dark leafy greens (today it’s spinach, baby bok choy, and red and green chard).
The USDA describes the following general health benefits by eating your vegetables:
- Eating a diet rich in vegetables and fruits as part of an overall healthy diet may reduce risk for heart disease, including heart attack and stroke.
- Eating a diet rich in some vegetables and fruits as part of an overall healthy diet may protect against certain types of cancers.
- Diets rich in foods containing fiber, such as some vegetables and fruits, may reduce the risk of heart disease, obesity, and type 2 diabetes.
- Eating vegetables and fruits rich in potassium as part of an overall healthy diet may lower blood pressure, and may also reduce the risk of developing kidney stones and help to decrease bone loss.
- Eating foods such as vegetables that are lower in calories per cup instead of some other higher-calorie food may be useful in helping to lower calorie intake.
And specifically, dark leafy greens are nutrition-dense, with loads of vitamins (Vitamin K, C, E and B), minerals (iron, potassium, magnesium and calcium) and fiber. Additionally they contain beta-carotene, lutein and zeaxanthin, which aide in disease prevention.
Second, the toppings. I’ve left this part for the end, because those co-workers of mine thought you might not still be reading if I let you in on my super power lunch protein choice, so here it is: a can of herring.
Surprised? Yep, herring is really good (I already like herring, but I love the lemon pepper variety), and there’s no need to add dressing, just dump the whole can on your salad! Sardines, smoked oysters and tuna — all on the “Good alternative” or “Best Choice” list on the Monterey Bay Aquarium Seafood Watch — are also delicious. They’re also very convenient and relatively inexpensive, especially if you stock up when they’re on sale. Fish is a super-food of protein choices, evidenced by the USDA Dietary Guidelines for Americans 2010:
“Mean intake of seafood in the United States is approximately 3 1/2 ounces per week, and increased intake is recommended. Seafood contributes a range of nutrients, notably the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Moderate evidence shows that consumption of about 8 ounces per week of a variety of seafood, which provide an average consumption of 250 mg per day of EPA and DHA, is associated with reduced cardiac deaths among individuals with and without pre-existing cardiovascular disease.”
A recent USDA paper says fish consumption is especially beneficial to pregnant and lactating women: “increased maternal dietary intake of long chain omega-3 fatty acids, in particular DHA from at least two servings of seafood per week during pregnancy and lactation is associated with increased DHA levels in breast milk and improved infant health outcomes, such as visual acuity and cognitive development.” (See complete February 2012 article.) And, just as I was getting ready to submit my blog, an article entitled “Brainpower Tied to Omega-3 Levels” appeared in the NY Times. How’s that for timing!
All this is not to say that chicken breast, tofu or beans are to scoff at, but do you get your USDA-recommended two servings of fish a week? What about that recommended two servings of chicken breast? Or tofu? Even beans don’t get a mention of how many times a week you should eat them. And for this I get razzed by my co-workers. Hmmph—bon appetite!
Oh January 1st, how I hate you. If you’re like me you’re still recovering from the month long holiday food hangover. With three months until spring and swimsuit season on the horizon, you’re feeling the pressure to lose the winter coat! As always, you make that infamous New Year’s resolution: TO LOSE WEIGHT!
“Gym membership here I come!”
“I will not touch another carb for the rest of the year!”
“No sweets ever again… after this one!”
“I’m on a new diet, I eat nothing and when I feel like I’m going to faint I eat a cube of cheese!”
Okay the last one is my favorite quote from the Devil Wear’s Prada, but working in the health field I have found that sometimes people actually think that’s a solution. We find ourselves making resolutions that eliminate entire food groups from our diets, because we think it will help us lose weight. The thing most people don’t know or realize is that sometimes the absolutes we make can be very harmful to our health, and in the long run can actually cause us to gain the weight back plus more.
So this year, let’s make an attainable, realistic goal. Here are three tips selected from www.choosemyplate.gov, to have a healthy year!
- Put a positive spin on it – instead of saying “I can’t eat any sweets at all!” try a few “I will” statements on for size:
- I will add 1 serving of fruits and vegetables to each meal.
- I will make half of my grains whole.
- I will choose water or low-fat milk more often.
- Build a healthy snack – instead of buying the expensive processed snacks, try these healthy tips:
Combine fruit and a dairy food for the morning munchies:
- Apple and cheese
- Banana and yogurt
Combine vegetables and a protein food for a p.m. pick-me-up:
- Celery and peanut butter
- Carrots and almonds
Combining these foods will help you stay fuller longer while increasing your nutrient consumption.
- Don’t discount physical activity – being healthy isn’t about just what you eat. Adults need 30 minutes of physical activity a day and children need 60 minutes. Just because you don’t have a gym membership doesn’t mean you can’t be physically active. Remember that 30 minutes can be broken up throughout the day.
Here are some tips to increase your physical activity incrementally, without breaking the bank:
- Start a walking club with your co-workers, neighbors or friends. You’re more likely to do it if someone keeps you accountable.
- Do what you like! If you hate to run, don’t do it. There’s no use in driving yourself crazy doing something you hate. If you like to dance, then turn the radio up and have fun!
- Do stretches, exercises, or pedal a stationary bike while watching television.
Remember to always consult your physician before beginning a rigorous exercise regimen.
May your new year be full of realistic, attainable, resolutions! Keep it positive. Select healthy snacks that help you stay full longer. Get moving so you have more energy during the day. For more information and health tips visit www.choosemyplate.gov.
Wishing you all a very healthy 2012!
