Last week (Jan. 31, 2011) the U.S. Department of Agriculture released its revised 2010 Dietary Guidelines for Americans. They are “the federal government's evidence-based nutritional guidance to promote health, reduce the risk of chronic diseases, and reduce the prevalence of overweight and obesity through improved nutrition and physical activity,” according to the press release.
I scanned the press release for news that cookies have been designated an essential food group. No luck. I confess, I didn’t read the entire 95-page pdf, but surely any such rocking revelations would have been reported in the press release.
Because more than one-third of children and more than two-thirds of adults in the United States are overweight or obese, the guidelines emphasize eating less and moving more.
I wasn’t surprised to see among its 23 key recommendations the advice to drink more water instead of sugary drinks, eat a variety of healthy foods and reduce salt. I expected the recommendation to eat more fruits and vegetables, but now it’s more explicit.
They say half of my plate should be covered in fruits and veggies. And mix it up – eat a variety of vegetables and protein sources. (I used to eat broccoli beef almost every day for lunch, until the day I found an insect in it.)
Many people think they have to spend more for nutritious meals, that fresh produce and meat are expensive. However, UC’s Expanded Food and Nutrition Education Program, or EFNEP, gives tips on how to make healthful food choices when you’re on a limited income. (Unless your name is Mark Zuckerberg, whose income isn’t limited?)
Chapter 6 of the Dietary Guidelines acknowledges that our environment – composed of school, workplace, social groups, culture and so on – influences our food and exercise choices. However, our communities don’t excuse our behavior because ultimately we make our own choices, it essentially says. We may have more access to healthy foods and opportunities to engage in physical activity than we realize. Connie Schneider, EFNEP Council chair, sees EFNEP as a vehicle to help families navigate their complicated food environments.
“Our educators facilitate group discussions to resolve food issues from shopping on a budget to getting their children to eat healthier foods,” said Schneider, who is also a UC Cooperative Extension nutrition advisor.
The EFNEP staff meets with families and children in a variety of community settings, including schools, shelters and transitional housing. Nutrition educators teach them how they can stretch their food dollars and still enjoy a healthy diet. They share recipes for nutritious meals that are simple to prepare as well as inexpensive. I love to eat, but have little patience for cooking. Watching a nutrition educator demonstrate how to make chili, I found myself thinking, “That’s so quick and easy, even I would do that.”
Sometimes a new way of preparing a familiar vegetable encourages me to eat more veggies.
The EFNEP website spotlights a Fresh Pick of the Month, such as cauliflower. The site gives the nutritional benefits of cauliflower, serving tips and recommendations for handling and storing the vegetable. It also provides a recipe for cauliflower soup.
The nutrition educators also publish monthly newsletters, in English and Spanish, featuring a recipe and healthful suggestions, such as walking to the restaurant and sharing entrees when you go out to eat. Although the nutrition program is designed to assist families and children whose resources are limited, we can all use the suggestions to improve our health and save some money.
I was struck the other day, when hearing about the world-wide soaring cost of foods, that we are incredibly lucky to live in California where food is so readily available to us. I was listening to this news on the radio as I was returning from my weekly trek to the grocery store and farmers market loaded with wonderful local whole fruits and vegetables of really high quality. I felt so fortunate and thankful at that moment that I could buy everything I wanted or pick what I wanted from my winter garden or my fruit laden citrus trees.
You can increase your own food security by planting food in your own garden . . . and you can start by planting a fruit tree now. February is the time that you can plant what are known as “bare-root” fruit trees, grapevines and berries. Fruit trees are now widely available at local nurseries or through mail order websites and catalogs.
Pick a tree fruit variety that you really love and something that you can’t purchase easily from the market. For me, this would be some of the more fragile freestone peaches such as Rio Oso Gem, or JH Hale. Or, you might pick a space saving self-pollenating variety of cherry such as Stella.
I always think great apricots are difficult to purchase in the markets so planting an apricot makes sense . . . they are relatively pest free, mostly self-fruitful and make beautiful landscape trees. My favorite apricot varieties include Patterson, Tilton and Harcot.
Just a note though, not all fruit varieties will grow in all climate zones. If you live in the San Joaquin or Sacramento valleys, then you are in luck because these are the primary stone fruit growing zones of California. If you live in the inland valleys of the coastal range, or in the foothill regions of the Sierras, you can grow most fruit varieties as well. If you are, however, on the coast or in Southern California, you may want to pick varieties that are "low chill." For information on the best varieties for your climate zone go UC's California Backyard Orchard website.
By keeping the fruit tree short, it is easier to harvest, deal with pest issues and cover with nets if you have a squirrel problem. For more information on how to prune a fruit bush or other fruit tree training systems, the UC Cooperative Extension Office in Sacramento County has an excellent horticulture note.
If you are unsure of how to choose, plant or care for your fruit trees, grapevines or berry bushes, there is a UC Master Gardener nearby who can answer your questions. Click here to find your local Master Gardener program.
I’m slow on the artisan EVOO wave. In December, after proofreading the new issue of California Agriculture - Growing Bigger, Better: Artisan Olive Oil Comes of Age, I purchased a bottle for my partner and the next day heard a TV comedian joke about people buying $60 bottles of olive oil for holidays gifts. (Then I felt cheap — I hadn’t spent that much!)
But the tall thin black bottle of December’s New Oil from Katz and Company, near Napa, was so fabulous I decided to start learning the extra virgin olive oil (EVOO) lexicon. Did I know for sure whether it was grassy, buttery, peppery or pungent? It certainly was green. Albert Katz this week told me why: “That’s the chlorophyll in the oil; it’s at its height in olio nuovo,” he said.
When the earliest still-green olives are crushed in November, a strong odor of fresh green fills the mill, he explained. The crush smells like fresh artichoke, even parsley, but most predominantly like grass. Katz has been in the business so long that when he catches a whiff of mown grass he looks around to see whether someone is crushing olives nearby.
Darn it, though, Katz sells their olio nuovo only in December, so it’s over. The limited production and short window of sales for olio nuovo, celebrating the first crush, is a tradition in all the major olive-growing regions of the world, including northern Italy, where the name originates. The oil is always unfiltered, cloudy, and as bold as it’s ever going to be. Katz calls it “the pungency of youth.”
This week sees the very end of the season. McEvoy Ranch has bottles of their olio nuovo for sale at their San Francisco Ferry Building store and online through this weekend (February 6). The McEvoy olio nuovo is green, robust, and peppery — peppery means it has a little burn in the throat, which is a desirable quality. (Bitter is a different matter; it’s tasted on the tongue.) Like all olio nuovo, the McEvoy new oil has sediment in the bottom of the bottle, and it has an unctuous quality, a little pleasantly thick and earthy in the mouth.
With the end of the olio nuovo season comes the release of the oils that have been stored for two months; they are already changing — more mellow, more golden — and the sediment will stay in the storage tanks. As they age through spring and summer, they’ll taste more buttery.
Climate affects the taste of oil. “Terroir” is what the environmental factors are called, explain Paul Vossen and Alexandra Kicenik Devarenne in the California Agriculture article on sensory qualities of olive oils. Katz tastes some roundness and softness in his oil this year, from the cool summer and late harvest.
Different varieties of olive trees produce markedly different aroma compounds. Tuscan varieties, grown by both Katz and McEvoy Ranch, have robust aroma profiles (full-bodied, pungent, complex). A few stores down from McEvoy at the San Francisco Ferry Building, Stonehouse sells its milder EVOO, pressed from Spanish olive oil varieties Mission, Manzanillo, Sevillano, Ascolano and Arbequina. The Stonehouse oil isn’t spicy; it doesn’t burn the throat.
Last week, Katz released its main oils for 2011: Chef’s Pick Organic Extra Virgin and Rock Hill Ranch Extra Virgin. Rock Hill doesn’t taste like the olio nuovo, because a significant proportion of the olives in it are Taggiasca, and they weren’t harvested until after the olio nuovo was made. Chef’s Pick, though, has the same profile, Katz says. Now I know a little of the language, I think I’m going to investigate further and buy a bottle before it sells out. If I wait until summer, I’m told the green will be gone and the grassiness turned more herbal.

A new UC Riverside citrus hybrid - combining the best traits of pummelo, mandarin and blood orange - could eventually become an ideal and healthful Valentine's Day present.
Valentine pummelo hybrid merges the large size and low acidity of Siamese Sweet pummelo, complex floral taste from Dancy mandarin and juicy red pulp from Ruby blood orange.
The fact that the fruit matures in mid-February, near Valentine's Day, isn't the only reason it was given the nickname 'Valentine.' Cutting the fruit lengthwise and turning it upside-down reveals flesh that looks a little like a vibrant red heart.
The new Valentine hybrid is also an excellent eating fruit.
"It has a complex flavor that is different from the most common pummelo, Chandler," said Tracy Kahn, senior museum scientist with the UC Riverside Citrus Variety Collection. "It is sweeter and floral and the bright red streaking pigmentation adds to the experience."
The fruit is unique in being grapefruit sized and containing anthocyanin pigmentation. Anthocyanin, an antioxident that gives the fruit its deep red color, may diminish the risk of heart disease, some types of cancer and LDL cholesterol accumulation.
Budwood for the new hybrid was released by UC Riverside to nurseries in 2009. A few retail nurseries will have a small quantity of Valentine trees this year; more are coming in the future.
"Valentine will be a specialty crop, for sure, and will probably be sold for restaurants, in farmers markets and specialty grocery stories once a year, at the peak of its season, around Valentine's Day," Kahn said.
How to eat this new fruit cocktail? Kahn suggests cutting off the top and bottom of the fruit, sliding off the rind, peeling off the pith and cutting out the sections inside the membranes with a knife.
There is a wide schism between the sleek mechanical harvesting machines that briskly traverse California’s fertile croplands versus the field worker with a machete and head-basket, or possibly a donkey laden with woven baskets, that is still most commonly found in many nations.
Produce loss continues to be a significant problem. Worldwide, it is estimated that as much as one-third of the produce grown is never consumed by humans (Kader, 2005). Many logistical challenges contribute to this loss, including: ineffective or absent cooling systems, slow and rough transportation, physical damage from rough handling, and poor sanitation conditions.
In 2010, one of the most popular free titles available on the Postharvest Technology Center’s website was “Small-Scale Postharvest Handling Practices: A Manual for Horticultural Crops.” Written by Lisa Kitinoja and Adel Kader, and currently translated into 10 languages, this title was downloaded by over 22,000 readers last year. While this useful resource is very popular in the United States among small-scale farmers, over 8,000 readers benefitted from the useful content translated into Indonesian, 4,000 from the Vietnamese translation, and over 3,000 from the Arabic translation. Readers learned information about the curing of tuber crops, designing picking poles and catching sacks to gently harvest fruit, and efficient designs for packinghouse layout. (Link to all ten translations are found under the section “Small-Scale Postharvest Practices” at: http://postharvest.ucdavis.edu/Pubs/publications.shtml.)
“Many simple practices have successfully been used to reduce losses and maintain produce quality of horticultural crops in various parts of the world for many years,” asserted Lisa Kitinoja of Extension Systems International. “You don’t necessarily need costly handling machinery and high-tech postharvest treatments to be able to deliver quality produce to the marketplace. However, effective management during the postharvest period is key to reaching the desired objective.”
While most California produce shoppers are grateful for the quality and variety available in our markets, it’s nice to know that an effort is being made to improve the produce available to others not quite as fortunate as we.
