USDA's nutrition advice doesn't align with spending

According to the USDA's dietary recommendations - which are represented in the MyPlate infographic - half the food Americans eat should be fruit and vegetables. However, the same agency allocates under one-half of 1 percent of agency funds to specialty crops like fruits and vegetables, reported Helene Bottemiller Evich in Politico.

For the story, Evich spoke to Glenda Humiston, vice president of UC Agriculture and Natural Resources (UC ANR), the research and outreach arm of the University of California. UC ANR extends science-based agricultural production and nutrition information to California farmers and communities. Humiston said California agricultural industry leaders have made it clear that they don't want traditional subsidies, like price supports.

"They want help with the infrastructure to do their jobs better," she said, including more funding for research labs and data collection that can help industry solve problems.

It isn't clear whether subsidies would reduce the cost of fruits and vegetables, nor does the potential of lower-cost healthy food ensure that people will eat it, the article said.

Many consumers also lack the time or the skills to prepare and cook their perishables. And some don't care for the flavor of healthful produce like kale, kohlrabi and rapini, to name a few.

The top fruits and vegetables consumed by Americans are potatoes (french fries) and tomatoes (primarily driven by ketchup). Only 14 percent of Americans consume 1.5 to 2 fruits and veggies per day, according to State of the Plate, a 2015 study on Americas' consumption of fruit and vegetables. (See below.) The USDA's dietary guidelines recommend 9 to 13 servings of fruit and veggies per day.

 

Protecting California’s parsley crop

When most people think about parsley, they likely think of it as an inedible garnish a chef places on their plate. But parsley is widely used in dried spice mixes, soups and other prepared foods as well as in salads and other recipes. Currently, California produces almost 2,600 acres of parsley at a value of $18 million a year, with Monterey and Ventura counties accounting for 49 percent of the state's parsley production.

California parsley is produced typically in high volumes and with high quality. However in the past few years, growers began to observe unfamiliar disease issues in their parsley fields. Leaf spots, blighted foliage and yellowed plants contributed to loss of quality and reduced yields. Steven Koike and Oleg Daugovish, UC Cooperative Extension advisors in Monterey and Ventura counties respectively, stepped in to investigate the new parsley problems. They collaborated with farmers and pest control advisers to understand the extent of the problems and to obtain samples of the diseased crops. 

The UC Cooperative Extension plant pathology diagnostic lab in Salinas was successful in isolating and identifying several pathogens that were responsible for causing the disease symptoms. Working with USDA, they found that three new diseases were present in California parsley crops: bacterial leaf spot, Stemphylium leaf spot, and Apium virus Y disease.

Two of these problems are seedborne, so future management will include the use of pathogen-free seeds. The Apium virus Y pathogen is found in weeds, so growers will need to remove poison hemlock, among others.

Previous to this research, some growers were spraying symptomatic fields because they believed that a disease called late blight was responsible for the disease symptoms. Growers have now ceased making these sprays, eliminating the use of unnecessary chemicals and saving costs.

When weeds make good eats

Last week, NPR offered up a novel weed control solution for all those yellow dandelions dotting your lawn: just eat 'em. The article includes a chef's recipe for dandelion flower fritters.

The idea that weeds can be edible pops up periodically, with articles suggesting one person's weeds are another person's salad bar, highlighting chefs who “have a way with weeds,” discussing ways medieval gardeners encouraged weeds, and even suggesting ways to eat away at invasive species. But is this something we should take seriously?

“We call these plants weeds because of the way we interact with them. They're in our gardens, they're in our lawns, and they're competing with plants that we prefer to eat,” said Lynn Sosnoskie, a weed scientist at UC Davis. “But a lot of the plants that are weeds here in the United States were brought here purposefully—to be eaten.”

Sosnoskie's doctoral thesis was on just such a plant, with the tasty name of “garlic mustard.” She has also worked at length on Palmer amaranth, a pernicious weed found in cotton fields that can be glyphosate-resistant. In response to one Georgia farmer asking in exasperation if he should just eat the plant taking over his fields, she did some preliminary research into eating Palmer amaranth.

“It's probably not feasible to eat our way out of a serious weed problem,” she said. “But I certainly feel like we can investigate them as other potential food sources.”

In fact, the Horticulture Innovation Lab at UC Davis has a project that is researching three “indigenous vegetables” in Africa, two of which — amaranth and black nightshade — are considered weeds in the United States. The vegetables can be nutritious and profitable options for small-scale farmers in Kenya, Tanzania, Zambia and elsewhere.

“I think some of these weeds have a lot of potential and are underutilized,” said Stephen Weller, horticulture professor at Purdue University, who leads the indigenous vegetables project. “In eastern Africa, these vegetables are very popular. And I really think that as we get more immigrants here from that region, there is going to be a market for some of these vegetables here.”

Though he holds a Ph.D. in weed science, Weller is now figuring out the best ways to cultivate amaranth and black nightshade — instead of to eliminate them. Before he started working with these plants, common assumptions held that they should be easy to grow because, well, they “grow like weeds.”

“But we found out that growing them is more intensive than we were initially led to believe — similar to growing any other vegetable,” Weller said. “They need water, they need fertilizer, and pests are a problem.”

Caveat emptor: Though weedy plants can indeed be a source of food, both scientists cautioned against thinking of weeds as a “free-for-all forage buffet.” Some plants may be toxic, and weeds in farm fields may have been sprayed recently. It is important to be knowledgeable of the plants and how they've been grown before trying to eat one.

Why growing fruits and vegetables matters

From broccoli to watermelon, California farmers grow more than 400 agricultural commodities. In 2011, California was the primary producer of almonds, artichokes, dates, figs, raisins, kiwi, olives, cling peaches, pistachios, dried plums, pomegranates and walnuts— accounting for nearly 100 percent of each of these crops grown in the United States.

When Americans think of “agriculture,” California may not be the first state to come to mind. But the Golden State — just this one state — produced nearly half of all fruits, nuts and vegetables grown in the U.S. in 2011 (source).

In this land of abundance, UC Agriculture and Natural Resources is asking researchers and the general public to discuss, “How do we sustainably feed 8 billion people by 2025?” at the Global Food Systems Forum, April 9. National and international panelists will share insights along the local-global continuum of “California Roots, Global Reach.”

What can Californians add to this conversation that hasn’t already been said? What are we uniquely positioned to address or to share? May I suggest: fruits and vegetables.

Of course, I’m not the first one to suggest this.

According to the Global Horticulture Assessment*, published by UC Davis with input from stakeholders around the world:

“Horticultural crops play a valuable role in food systems by diversifying diets and fostering increased dietary consumption of micronutrients and other plant products known to benefit human health (fiber, antioxidants, etc.).

"Changes in production systems over the past 40 years favor an increase in cereal-based diets. The emphasis on staples has resulted in reduced dietary diversity and the displacement of traditional crops that were important sources of micronutrients such as iron, vitamin A, B-12 and zinc.”

A lack of dietary diversity can signify a serious issue in developing countries where daily eating patterns are centered on starchy staple foods — with very few fruits, vegetables or animal-based products. Reduced dietary diversity can point to micronutrient deficiencies, which could be addressed through fruit and vegetable consumption.

Growing fruits and vegetables — to be eaten and sold — has the potential to improve diets while also boosting incomes.

*The "Global Horticulture Assessment" called for the creation of the Horticulture Collaborative Research Support Program, and serves as a guiding document for the program. With funding from USAID, Horticulture CRSP is led by UC Davis and builds international partnerships for fruit and vegetable research that improves livelihoods in developing countries.

UCCE makes Southeast Asian vegetables easy to eat

Most Americans gravitate toward the familiar in supermarket produce aisles. But some creative shopping unveils a tremendous diversity of edible vegetables that can turn an ordinary menu into a much more interesting cuisine.

At certain roadside stands, at farmers markets that cater to diverse clientele and in small Asian supermarkets, adventurous Californians can buy vegetables like bitter melon, Chinese long beans, opo and luffa. Finding them is the first step, knowing how to prepare them is another matter. UC Cooperative Extension has made these less familiar vegetables more accessible by creating a collection of easy-to-cook and nutritious Southeast Asian vegetable recipes.

The recipes were developed by UCCE nutrition educators in Fresno and the statewide UC Expanded Food and Nutrition Education Program team with Richard Molinar, a UCCE advisor in Fresno County. Connie Schneider, director of the UC Youth, Families and Communities Program, and Molinar started by researching the traditional usage of Asian vegetables. They modified some ingredients and procedures in the recipes to simplify preparation and improve the nutritional profile.

“We minimized the number of ingredients in each recipe, added clear measurements and tested the dishes,” Schneider said. “They are delicious.”

For the last 18 years, Molinar has worked with small-scale farmers in Fresno County, which boasts the largest concentration of Hmong farmers in the U.S.  Fresno County is also home to farmers of other ethnicities from Laos, China and Vietnam. Molinar and his assistant, Michael Yang, have introduced Southeast Asian immigrant farmers to the latest farming technologies, helped them develop plans to ensure the safety of the food they grow, and worked with them to find new marketing opportunities. Many of these farmers have begun growing vegetables common in California, and most have also kept some space on the farm for the vegetables of their homelands.

The UCCE educators recognized that the rich culinary traditions of local Southeast Asian immigrants could be adapted and used by people of all cultures to increase their consumption of vegetables. Besides, encouraging consumption of Southeast Asian vegetables adds new marketing opportunities for the farmers.

“This has been a unique opportunity to bring UCCE’s farm advisors and nutrition educators together to assist farmers and the public,” Molinar said. “These recipes will encourage more people to buy these nutritious vegetables, expanding the market for the growers.”

The 12 recipes are printed on cards, each with photos of the fresh vegetable and background information. For example, the recipe card for “bitter melon stir fry” notes that the crinkly skinned vegetable is native to India and is eaten when young and green, as bitterness increases with age. The recipe is accompanied by a photo of the prepared dish and complete nutrition facts per serving.

Most people are familiar with luffa after it has dried into a natural scrubby. It is often found near beauty products in stores and purchased to exfoliate the skin. However, the UCCE recipe card for “luffa and prawns” notes that fresh green luffa has a similar but sweeter flavor than zucchini summer squash when stir fried. Either the smooth or angled varieties of luffa can be used in the recipe. 

"I grew up with zucchini," Molinar said, "but I prefer the flavor and texture of angled luffa."

The printed cards will be distributed at farmers markets where Southeast Asian vegetables are sold, and they are available on the Fresno County UC Cooperative Extension website. Farmers who sell Asian vegetables at farmers markets may pick up 10 packets of recipes for free at the UC Cooperative Extension in Fresno, 1720 S. Maple Ave., Fresno.
