With a population of more than 10 million residents, Los Angeles County faces enormous challenges related to poverty and hunger. Over a million L.A. County residents face hunger or food insecurity every day, according to the Los Angeles Regional Food Bank. A Sept. 6 Los Angeles Times article detailed the problems faced by local food pantries, as they struggle to cope with a demand for food that’s risen by 48 percent in just two years. At the same time, with cheap fast food, and limited access to affordable healthy food, childhood obesity is an increasingly critical problem. Forty percent of middle-school age children in Los Angeles County are now classified as overweight or obese.
Local elected officials are embarking on an effort to more systematically address these issues. Last fall, Los Angeles Mayor Antonio Villaraigosa convened a group of experts, bringing together community organizers, restauranteurs, public health experts, employers, farmers, urban gardeners and others to form the Los Angeles Food Policy Task Force. This was a short-term effort to gather information and make recommendations to the mayor and decision makers. The task force recently released a report, “The Good Food for All Agenda: Creating a New Regional Food System for Los Angeles,” outlining an ambitious plan for improving access to healthy food in Los Angeles.
The task force defined “good food” as food that is healthy, affordable, fair (meaning that all participants in the food supply chain receive fair compensation) and produced sustainably, using principles of environmental stewardship.
Some of the task force's recommendations were:
- Develop a regional food hub, which can coordinate supply and demand for local, sustainable food. (Farms in several counties were included in the definition of “local” for the Los Angeles area).
- Encourage school districts to procure sustainable, local food and provide children with higher quality lunches.
- Promote and improve participation in the Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program.
- Facilitate neighborhood food production by streamlining permits for community gardens, and expanding joint use agreements where schools offer their land for community gardens.
- Start an ongoing regional food policy council, which will include both city and county decision makers and community leaders.
While Los Angeles is just one of a number of major metropolitan areas to form a task force of this nature, it’s exciting to see the state (and nation’s) most populous county addressing food policy issues. Although Los Angeles County has a relatively small number of farms, neighboring counties, including Ventura, still have significant commercial agriculture. Policies like those recommended by the L.A. Task Force not only improve choices and healthy options for consumers, they can also lead to new markets for local farmers.
UC ANR programs, such as UC Cooperative Extension in Los Angeles County, offer research-based expertise in urban gardening, nutrition education, sustainable food production and more, and serve as a resource for local policymakers and residents working to improve food access.

Improving access to local produce is part of the "Good Food For All" Agenda.
While numerous studies have shown that organically grown foods contain fewer pesticide residues, there has been little convincing scientific evidence that organic crops taste better or are more nutritious.
Now a two-year evaluation of California strawberries has found that organic strawberries, while lower in phosphorus and potassium, had significantly higher “antioxidant activity and concentrations of ascorbic acid [vitamin C] and phenolic compounds, longer shelf life, greater dry matter, and for ‘Diamante’, better taste and appearance” than conventionally grown berries.
Published in the September 2010 issue of PLoS ONE, an open-access, peer-reviewed journal, the study looked at 13 pairs of commercial organic and conventional strawberry agroecosystems. The fields were all in the Watsonville area, where 40 percent of California strawberries are produced. All of the paired farms had been in production at least five years and had comparable soil types. The researchers collected multiple samples in 2004 and 2005, and evaluated the strawberries for minerals, shelf life and phytochemicals. A sensory panel compared the organoleptic properties of three different varieties of fruit.
Regarding post-harvest durability, the organic berries — despite no fungicide applications — had significantly less gray mold and significantly less loss of fresh weight two days after harvest than conventional berries.
“These results indicated that the organic strawberries have a longer shelf life than conventional strawberries because of slower rotting and dehydration, perhaps due to augmentation of cuticle and epidermal cell walls,” the authors wrote.
Mark Bolda, UC Cooperative Extension farm advisor for strawberries in Santa Cruz County, said there are a number of variables that could account for a reduction in gray mold infestation.
“For example, organic plants are smaller in size, have a smaller canopy and consequently are drier because of more air circulation,” Bolda said. “Flowers and fruit subsequently present a drier and less appealing host for this fungus.”
Not surprisingly, the study found that “soils on the organic farms had significantly more carbon and nitrogen, greater microbial biomass and function, and great functional gene abundance and diversity.” The authors attributed this to the fact that the conventional sites were fumigated with methyl bromide and treated with synthetic pesticides, while the organic sites were not and received double the amounts of compost.
The researchers were affiliated with Washington State University, Pullman; Utah State University, Logan; Oak Ridge National Laboratory, Oak Ridge, Tennessee; and University of Oklahoma, Norman.
U.S. consumers continue to clamor for organic foods, sales of which have increased nearly six-fold since 1997 to $21.8 billion in 2008 (3 percent of total U.S. food sales). California produces 87 percent of the nation’s strawberries, of which nearly 5 percent are organically grown.
Every August, I pack up my saddle, cowboy bedroll, chef’s knife and my vacation hours and head to a pack station high in the eastern Sierra Nevada between Mammoth and Bishop. A couple days later I’m out on trail, usually riding somewhere in the national parks of Kings Canyon, Sequoia or Mt. Whitney, with strings of pack mules in front of me.
The author heading to work
The packers—cowboys who load and manage the mules—and I take paying guests, their gear and our supplies into the back country for days, even weeks at a time. The guests hike or ride with us to each camp, where the packers unload the patient mules and I set up my kitchen. That’s when my real work begins.
Pack mules headed up a steep trail
The food for each trip is kept in large, lockable, bear-proof boxes with heavy leather straps that hook onto the pack saddles. Perishables are kept in soft coolers in the bear boxes; cans and bottles are padded with other items in cardboard so they don’t break or rattle together and worry the mules. At night I cover the bear boxes with a tarp, then a bear-alarm system of stacked pans.
During the day, when we’re in camp, the bear boxes are kept covered in the shade of pine trees or granite boulders. Our cowboy menus are practical and reflect what food must be eaten soonest: the first dinner is always burgers, the second, chicken. I remove produce from plastic bags, which hasten spoilage, and keep it in brown bags or wrapped in clean dish towels.
A tidy kitchen at midday. The bear box in the sun holds garbage, the wooden box holds cooking utensils.
After 6 years, I have discovered some secrets of back country cooking: people are always very, very hungry from exercising in the high elevations, which are often above 10,000 feet. But even hungry they still appreciate good, well-prepared and well-seasoned food. The difference between a packaged, instant pudding and a slowly steamed, stovetop apple crisp are obvious. Pancakes cooked with thin layers of ripe peaches are tastier than plain ones. And under no circumstances do you overcook the steaks, even when you’re negotiating damp and uncooperative firewood.
The pack station outfitter supplies delicious meat; the thick bacon alone is worth the trip. I grill chops, simmer stews and roast thick cuts of meat that have been deep frozen for days. The hearty meat dishes are not just for tradition; the packers rise well before first light to wrangle the grazing animals, and protein fuels their long days. But our guests are health conscious and like produce as well.
The lettuce that best survives the days of jostling in the bear-proof boxes is iceberg, but salads of iceberg, tomatoes and cucumbers with packaged dressing get downright dull. Instead we serve a popular broccoli salad or my improvised cole slaw, which varies with every trip depending on what I have in my bear boxes. If there is any left over, I put it out when guests are making their sandwiches for lunch the next morning. Although coleslaw in a sandwich is a mess to eat—believe me, I have done so, leaning over my horse’s mane—its crunch and flavors makes the sandwiches zing.

1 head broccoli
1 small red onion
½ cup dry roasted sunflower seeds
Dressing: mayonnaise, apple cider vinegar, dry thyme, salt and pepper
Trim the broccoli into very small florets. Put dressing ingredients in bowl and whisk. The dressing should be thin enough to coat broccoli nicely but not so it puddles in bottom of bowl. Toss dressing over salad. Sprinkle sunflower seeds generously over the top.
Serves 8-10 as a side dish; exact amounts are not critical
red cabbage, if available
2 zucchini, green skins primarily
slivered or sliced toasted almonds
green or red pepper
Optional: a can sliced water chestnuts or crushed pineapple
Dressing: Mayonnaise, apple cider vinegar and white wine vinegar (I use both), celery seed (important), salt and pepper to taste. Add mayo and vinegar so dressing is creamy, not gloppy.
With a sharp chef’s knife, thinly slice the cabbage. Pick through and remove any thick white ribs, then dice cabbage as finely as you have patience to do. Grate carrots and zucchini skins (I feed the soft zucchini centers to the mules). Finely dice green pepper and red onion. Toss vegetables together and add cranberries and nearly all the almonds. Look at the balance of the salad: you want a cranberry and a few almonds in nearly every bite. Whisk dressing together and pour over slaw, tossing to coat. Set aside in a cool place and just before serving, sprinkle with remaining almonds.
Remember that snow on the foothills back in May? That cold spell delayed the apple harvest in El Dorado County about 10 days, but the ranches of the Apple Hill Growers Association are now open for visitors. Gravensteins are already ripe and the first crisp and juicy Galas are ready to pick, with Jonagolds close behind. September is the perfect month to visit the ranches, pick your own apples and maybe stop for a glass of wine or a slice of fresh apple pie.
More than 50 Apple Hill Association member ranches welcome the public onto their small foothill farms every fall with fruit stands, U-pick opportunities, wineries, apple pressing, bake shops, and attractions including live music, old-time steam engines, craft fairs, apple-head carving classes and pie-eating contests. The association hosts a website to help visitors find farmstands, where to pick their own fruit or what events are scheduled.
Apple Hill was born of hard times. In the 1960s, pears were the chief source of income for the area. But a disease known as "pear decline" was ravishing the trees. A small group of local farmers met with the UC Cooperative Extension farm advisor and the county agricultural commissioner to discuss how to save the farms. Since most of the farms had a few apple trees on the land, they decided to try inviting people from the Sacramento Valley up the hill to buy some apples and a fresh-baked pie or two as a stop-gap measure until they could figure out a solution. The apple and pie event was instantly successful, the growers formed their association and planted more apple trees, and Sacramento Valley families have made a tradition of the short drive to Apple Hill every fall for the past 50 years.
All over California, apple growers are harvesting now. California is fifth in the United States in apple production, and many of California's growers have organized together to share their harvest season directly with visitors. In San Bernardino County, about 90 minutes from Los Angeles, The Oak Glen Apple Growers Association offers U-pick apples, U-press cider, hayrides, farm animals, tours and history. In Sonoma County, you can check the Sonoma County Farm Trails to find an apple ranch to visit. To find other apple ranches, check the California Apple Commission's site.
When you do pick your own apples at one of the many ranches open to the public, you may be pleasantly surprised to learn that you don't have to climb any ladders. In fact, due to liability concerns, most U-pick operations now make sure that you keep both feet firmly on the ground by planting dwarf varieties of fruit trees for visitors' picking.
Just picked, crisp sweet apples can't be beat for good eating. They are also good for you; an apple a day just might help keep the doctor away. apples are very low in saturated fat, cholesterol and sodium, and are a good source of dietary fiber and vitamin C.
Apples will keep for three or four months, or even longer if stored properly. When harvesting, do not remove the stems from apples that will be stored. Be sure to store only apples without bruises, insect or disease damage, cracks splits or mechanical injury. Store apples at around 40 degrees F for best results. You may also want to wrap each apple in newspaper to keep them from touching each other.
Apples are also great for cooking. Here's an apple crisp recipe from www.momswhothink.com:

Fishing has resumed in the Gulf of Mexico, but the Deepwater Horizon/BP oil spill that began in April has dampened consumer appetites for seafood. Consumers have concerns about the effect of the oil spill on gulf seafood, and some are eating less seafood now.
In a June 2010 telephone survey of 1,076 consumers conducted by University of Minnesota’s Food Industry Center, Louisiana State University AgCenter and the National Center for Food Protection and Defense, 89 percent said they are concerned about the spill’s effects on gulf seafood, and 50 percent are “extremely concerned.” When asked about their own eating habits, 54 percent of respondents said the oil spill has affected their seafood consumption somewhat, 44 percent said they will not eat gulf seafood, and 31 percent said they will eat less seafood regardless of its origin.
The gulf produces blue crabs, crawfish, oysters, shrimp and about 86 species of fish including albacore, channel catfish, red snapper and tilapia. Consumers are worried about crude oil and dispersants contaminating the food, but experts say gulf seafood is safe to eat.
“There has been no evidence of tainted seafood entering the marketplace,” says Pamela Tom, California Sea Grant advisor. “Seafood from the gulf has never been as highly inspected as it has been now. Harvest waters are re-opened only after extensive government testing proves that the seafood has not been tainted by oil from the spill.”
The US Food and Drug Administration (FDA), National Oceanographic Atmospheric Administration (NOAA), and the Gulf Coast states cooperate in unison on a protocol to determine when closed federal harvest waters can be re-opened.
Federal inspectors routinely do sensory evaluations or “sniff test,” a rapid method of testing seafood. Highly trained regulatory inspectors can detect oil taint within seconds. More time-consuming, sophisticated chemical analyses of the seafood are also used. Recently, the California Animal Health and Food Safety Laboratory, operated by the UC Davis School of Veterinary Medicine for the State of California, was selected by the FDA to conduct chemical analyses in monitoring seafood from the Gulf of Mexico for toxins related to the oil spill.
To help prevent oil-tainted seafood from reaching consumers during the oil spill, Tom joined a national team to disseminate information on seafood safety steps and monitoring for contaminants in seafood shipments and harvests from unapproved waters. She worked with the FDA, the NOAA Seafood Inspection Program, Louisiana State University and the University of Florida to assemble an oil spill website with resources for gulf fish growers, harvesters, processors and seafood buyers.
So how can consumers tell if seafood is good to eat?
“Buy from reputable dealers,” Tom advises. “Smell it. If seafood smells a little fishy, it could be past its prime, but may still be safe to eat.”
At home, consumers also need to practice sanitation and proper temperature cooking and holding controls. Mixing raw seafood products with cooked product is a formula for disaster, she says. Cooked foods should be kept separate from raw foods, which may have natural bacteria present. Spoilage bacteria compete with pathogenic bacteria, but proper cooking of raw fish at 145 degrees F for 15 seconds destroys the bacteria. If pathogens are re-introduced after the seafood is cooked, under the right conditions pathogenic bacteria can grow and may lead to foodborne illness.
“Some pathogens will grow in your body, while other pathogens may create toxins in food,” Tom says. “Some toxins are heat stable and some are not. Food safety is a very complex situation and some consumers are more susceptible to foodborne illness than others.”
Safe cooking and holding practices at home include placing seafood on ice or in the refrigerator or freezer soon after buying it. The temperature holding range should be below 40 degrees F or above 140 degrees F. Bacteria that can cause foodborne illness can grow quickly at warm temperatures between 40 degrees F and 140 degrees F.
