Summer brings an abundance of luscious and healthy fruits and vegetables. It's easy to buy more than we can eat, which sometimes results in #foodwaste.
In a guest blog post for the UC Food Observer, UC researcher Wendi Gosliner (part of the team at UC ANR's Nutrition Policy Institute, a cutting-edge unit that's using research to transform public policy) shared this observation:
“Food waste presents a major challenge in the United States. Estimates suggest that up to 40% of the food produced nationally never gets consumed, causing substantial economic and environmental harms. Wasted food utilizes vast quantities of precious land, water and human resources, yet rather than nourishing people, it feeds landfills, producing methane gasses that poison the environment. Much of the food waste (43%) occurs at the household level."
What history can teach us
Here's my take on food waste. It goes back in part to lessons I've learned from studying World War I (WWI), when the American government set food conservation goals (along with goals for local food production via Liberty – later Victory – Gardens). I'm a big proponent of both reducing food waste and producing more food in communities via school, home and community gardens. Big point: the World War I poster included in this post has advice we'd be well served to heed today.
It's an iconic poster from World War 1. Food…don't waste it. The image is regularly shared on Twitter and Facebook.
Period piece or photoshopped image?
The original was produced in 1919 by the United States Food Administration, under the direction of the newly appointed food “czar” – Herbert Hoover.
The poster was reissued during World War II. It's been revised in recent years by individuals and organizations interested in encouraging an ethos incorporating local foods and sustainability.
While I'm the UC Food Observer, I also dabble in the history of wartime poster art. I'm often asked if this is a contemporary mock-up made to look and feel vintage.
It's not a mock-up. It's the real deal, produced 95 years ago, with messages we should embrace today.
The original poster: Yes: ‘buy local foods' is rule 4
The original poster has six rules that we'd be well served to follow today. The fourth rule – buy local foods – is somewhat of a surprise to people today, because the notion of buying local seems somewhat modern. But in WWI, the U.S. government encouraged the local production and consumption of food, in part, to free trains to more effectively ship troops and war matériel.
Tackling food waste through preservation: today's Master Food Preserver Program
Many land grant institutions, including the University of California, host master food preserver programs. These programs teach best practices on food safety and preservation to volunteers. The extensive training program prepares the volunteers to work in their community educating others on the safe practices of food preservation, including pickling, drying, freezing, canning and fruit preserves.
Thinking about gardening? Do we have resources for you!
The University of California sponsors the state's Master Gardener Program, which fields more than 5,000 volunteers in communities across the state. The Master Gardener Program is a national program, housed at the land grant institution in each state, but it's also connected to the USDA. Free gardening resources are available here. Advice to grow by…just ask.
Food waste is both an ethical and environmental issue. It should concern us that we waste nearly 40% of the food we produce and purchase in this food-abundant nation.
For an interesting comparative statistic, consider this: our nation produced about 40% of the fruits and vegetables we consumed on the American home front in World War II in school, home, community and workplace gardens. That was the result of the iconic Victory Garden program (which actually got its start in WW1).
Three messages then: participate in the national effort, commit to wasting less food, and if you can, produce some food of your own.
Notes: There are many additional resources about #foodwaste.
Read: Dana Gunders of the National Resource Defense Council authored a 2012 report called Wasted that sparked much of this work. Dana also authored a book called Waste Free Kitchen Handbook: A Guide to Eating Well and Saving Money by Wasting Less Food, both of which are great reads.

9th Biennial Childhood Obesity Conference. Since it's founding 18 years ago by UC ANR Specialist Pat Crawford, it has grown from a small gathering of California researchers, educators, and health care professionals to the nation's largest gathering on the topic of pediatric obesity/overweight.
So today seems the perfect time to revisit a 2015 conversation with Rose Hayden-Smith, UC's Food Observer, and Crawford, now the Senior Director of Research at UC ANR's Nutrition Policy Institute. As Pat stated in her interview—
“Not changing is risky. The United States – along with Mexico – has the highest obesity rates in the industrialized world. With these extraordinarily high obesity rates, we are on a path toward ever-rising chronic disease rates including not just diabetes, but also heart disease and some cancers, increasing health care costs and reducing productivity.
Even more alarming, is a little known fact that 23 percent of the adolescents in this country currently have pre-diabetes or diabetes as measured by actual blood tests in our largest national study of health (NHANES). Something is seriously wrong in a society such as ours where so many children are growing up with such a high risk of preventable disease.”

Lunches served in the National School Lunch Program have higher nutritional quality than lunches brought from home, according to the largest comparison study conducted to date.
Published in the November 2016 issue of the Journal of the Academy of Nutrition and Dietetics, the study, conducted by researchers at UC's Nutrition Policy Institute, involved nearly 4,000 elementary school students in Southern California.
“This rigorous study confirms what we have long known: The school lunch program, which has served the country's students since 1946, makes an invaluable contribution to their nutritional well-being, their health and their academic performance," said Lorrene Ritchie, Ph.D., director of the Nutrition Policy Institute and a senior author of this study. "And thanks to the recent, improved nutrition standards, it will only provide stronger, more essential support for our children's success.”
School lunch consumption was associated with higher overall diet quality. School lunch eaters also consumed diets that were higher in dairy-rich foods, lower in empty calories from solid fats and added sugars, and lower in refined grains than students who ate lunches from home.
Established in 1946, the National School Lunch Program is a federal nutrition assistance program that provides nutritionally balanced, low-cost or free lunches in over 100,000 K-12 schools throughout the United States. School lunches are required to meet certain nutrition standards based on the latest Dietary Guidelines for Americans. New requirements increase the availability of fruits, vegetables and whole grains and reduce sodium and fat in school lunches. Guidelines on calorie limits are set to ensure age-appropriate sized meals for grades K-5, 6-8 and 9-12.
During the 2014-15 school year, the program served lunches to about 30.5 million children each school day. More than 21.5 million of these students qualified for free or reduced-price service. Given the program's broad reach and its targeting of low-income children, the nutritional improvements shown in this study are of considerable benefit to needy students for whom school lunch may represent roughly one-third of their daily calories.
Since the study was conducted, new and more rigorous nutritional standards have been implemented, thus increasing the likelihood that school lunches are contributing to healthy overall diets – and reversing the extremely worrisome obesity epidemic. Currently as many as one-third of U.S. youth are obese or overweight.
One in five Mexican-American children is obese, according to national statistics. While scientists agree that diet and exercise play a role in obesity, studies also suggest that children who don't get enough sleep may also be at increased risk for obesity. Does this mean that children who don't get enough sleep are more likely to become obese due to poor eating habits and being less physically active?
The National Institutes of Health has awarded $895,620 to Suzanna Martinez, Ph.D., assistant researcher for UC Nutrition Policy Institute (NPI) in the UC Division of Agriculture and Natural Resources, to try to answer that question. This will be the first pediatric study to examine health behaviors that link sleep to obesity in Mexican-American children.
Studies have shown that adults who are short on sleep may experience a change in metabolism and hormones, causing the person to eat more and to be more sedentary the following day.
To explore how sleep affects child obesity, Martinez will examine social and cultural factors that may impact Mexican-American children's sleep and, in turn, how sleep affects their diet and physical activity.
“Some researchers just focus on diet, some researchers just focus on physical activity, while other researchers say it's all about the environment so we have to improve the environment in terms of food environment and opportunities to be active,” Martinez said. “There's very little research that tries to target all three aspects of health behavior – sleep, diet and physical activity – because there are so many factors to consider. We have to know which will make the biggest impact on obesity prevention. Is it sleep, diet or physical activity or a combination of all three?” Currently, programs are heavily focused on diet and/or physical activity.
Social and cultural factors may affect sleep
Martinez is essentially combining three different studies into one to evaluate the context of sleep and how it impacts obesity. The five-year study will occur in two phases.
She'll begin by looking at the culture, environment and socioeconomic status of the Mexican American families to see which factors may relate to sleep duration.
For example, Martinez said, “If less acculturated Mexican-American parents have stricter or earlier bedtimes for their children, is that protective for getting optimal sleep, less protective or does it even matter?”
Living in crowded housing or in neighborhoods with high crime, homelessness and drugs can impact sleep for urban Latino families, Martinez learned from interviews with Latino parents for a study she published in 2015.
Sleep and physical activity and diet
The second phase of the study will involve evaluating the sleep duration of 40 Mexican American kids, ages 8 to 10, in the San Francisco Bay Area over two summers.
To record their sleep and physical activity, the participating kids will wear accelerometers during the day and while they sleep. The small, pedometer-like devices are worn on a belt around the hip.
For the first week of the three-week study, the children will be asked to get their normal sleep. During the second week, half of the children will be asked to sleep for less than 8 hours and the other half will be asked to sleep at least 10 hours. The third week, the two groups will switch over to the other sleep schedule.
Their diets will be measured using 24-hour dietary recalls. On Friday and Saturday, children will be asked what he or she ate the day before (Thursday and Friday). Starting with breakfast, the children will report what they ate and drank for meals and any snacks.
Martinez will evaluate whether healthy sleep or restricted sleep the previous night impacts the children's diet and physical activity the next day.
“With the crossover study, we will be able to see how kids compare when they get their usual sleep, healthy sleep or not enough sleep and how that impacts how much they eat and how much they move the next day,” she said.
No U.S. sleep guidelines
To maintain a healthy weight, U.S. Office of Disease Prevention and Health Promotion recommends that children get at least 30 minutes of physical activity daily and the Dietary Guidelines for America recommend that children eat a nutrient-dense and calorically balanced diet. The government office currently has no national sleep guidelines for Americans.
In a 2014 study, Martinez found that 82 percent of Mexican-American children ages 8 to 10 obtained less than the 10 to 11 hours of sleep the National Sleep Foundation recommended before 2015. Under the network of sleep researchers' new sleep recommendation of 9 to 11 hours for this age group, 20 percent of children received less than adequate sleep.
“There needs to be more research on sleep duration before we can say, ‘Sleeping this amount of time will help prevent obesity,'” Martinez said.
If her hunch is correct, promoting optimal sleep (at least 10 hours for school-age children) may be an effective way to reduce childhood obesity, and understanding the role of culture in obesity among Mexican-American children who have some of the highest rates obesity will be a key to designing effective solutions.
Research has shown that obesity contributes to numerous lifelong health problems, including heart disease, stroke, diabetes and high blood pressure. One in four overweight children become obese as an adult, and diseases like diabetes are presenting earlier than adulthood. National data show that 14 percent of white children are classified as obese, while 21 percent of Latino children are obese. With Latino children at increased risk, Martinez is committed to finding the causes of this disparity and to develop effective ways to reduce obesity among Mexican-American children.
This child obesity study is funded by a K01 Career Development Award from the National Institutes of Health National Heart, Lung and Blood Institute. Martinez has also been accepted into the K Scholars Program at UC San Francisco, which will provide her with peer support and mentorship to conduct the study.
With an eye on reducing childhood obesity and improving overall health for children, the U.S. Department of Agriculture announced the final rule for snacks at schools. The rule made final on July 21 includes requiring snacks served at school to meet nutritional standards similar to those required of school meals.
Lorrene Ritchie, director of UC ANR's Nutrition Policy Institute applauds the USDA for their recently final Smart Snacks in School rule, which complements the nutritional improvements made to school lunches and breakfasts through the Healthy, Hunger-Free Kids Act.
Creating school environments that offer more healthful foods such as fresh fruits, vegetables and whole grains can also influence the way children eat at home and away from school.
“No single setting has the potential to influence the nutrition of more children than schools,” said Ritchie.
“Research – conducted by our Nutrition Policy Institute and others – has demonstrated that the healthy school foods and beverages consumed by children have a positive impact on their overall diet quality,” she said.
USDA also now requires any food or beverage that is marketed on school campuses during the school day to meet the Smart Snacks standards. Children are a target market for many foods and beverages that contain low nutritional quality and high calories that contribute to excess weight. To be advertised on a school campus, foods and beverages must meet the same Smart Snack standards for items sold or served by a school, according to the new Local School Wellness Policy rule.
“We are starting to see a leveling of child obesity rates in some places and changes to the school food environment are essential to furthering this progress,” said Ritchie.
Providing a consistent source of nutritious food at school will help the approximately 6.2 million California K-12 students develop healthy eating habits for life.
