  • USDA Launches TRUMP Mission to Vietnam to Expand Market Access for American Farmer

    The U.S. Department of Agriculture launched a Trade Reciprocity for U.S. Manufacturers and Producers (TRUMP) Mission to Vietnam this week to open new markets, strengthen export opportunities, and secure fair, reciprocal trade for American farmers, ranchers and producers.

    Under Secretary for Trade and Foreign Agricultural Affairs Luke J. Lindberg is leading a delegation representing a cross-section of American agriculture that stands to benefit from expanded access to one of Asia’s fastest-growing markets.

    “American farmers, ranchers and producers thrive when they have strong, reliable markets for their high-quality products,” said Under Secretary Lindberg. “By strengthening our trade relationship with Vietnam, we’re opening doors for U.S. agriculture, ensuring they have a fair chance to compete and succeed, and that they can bring the benefits of that success to communities here at home.”

    Vietnam has become a top destination for U.S. agricultural products. In 2025 alone, agriculture, fishery and forest products exports surged by 45% to a record $5.6 billion, making Vietnam the United States’ eighth-largest market. This mission will build on that momentum by expanding market access, connecting suppliers with new buyers, and advancing negotiations under President Trump’s strategy to deliver fair, enforceable trade for American farmers and ranchers.

    During the visit, USDA’s Foreign Agricultural Service will lead industry tours, host business meetings, and engage with Vietnamese officials to advance U.S. trade priorities and support U.S. producers. The delegation includes:

    1. California Fresh Fruit Association – Fresno, Calif.
    2. California Prune Board – Roseville, Calif.
    3. Potatoes USA – Denver, Colo.
    4. USA Poultry & Egg Export Council – Tucker, Ga.
    5. U.S. Dairy Export Council – Arlington, Va.
    6. U.S. Grains and Bioproducts Council – Washington, D.C.
    7. U.S. Meat Export Federation – Denver, Colo.
    8. U.S. Soybean Export Council – Chesterfield, Mo.
    9. U.S. Wheat Associates – Arlington, Va.
    10. Washington Apple Commission – Wenatchee, Wash.

    This is USDA’s third TRUMP mission of 2026. Later this year, USDA will return to Vietnam with a broader agribusiness trade mission to continue expanding opportunities for U.S. food and agricultural exports.

  • Mechanical Pruning Trial in ‘French’ Prune – Through Year Three

    Work continues at the mechanical pruning trial site in Red Bluff. The trial, funded by the California Prune Board and led by Dr. Rich Rosecrance at Chico State, was initiated in 2019 and aims to identify lower cost pruning alternatives for growers without compromising yield or fruit quality. The study site is an orchard planted in 2011 at a spacing of 15’ x 18’ on Myrobalan seedling rootstock and irrigated with buried drip. This is a vigorous, well managed orchard with a history of producing 4-5 dry ton/acre. The study treatments are:

    1. Fall: Grower standard — ladders and loppers pruning, no topping (i.e. ‘control’).

    2. Spring: Topping and hedging both ways — cutting 5 sides of the canopy, with the tree row and across the tree row, plus topping (i.e. ‘boxed’).

    3. Fall: Topping and hedging both ways — cutting 5 sides of the canopy, with the tree row and across the tree row, plus topping (i.e. ‘boxed’).

    4. Spring: Hedging both sides of the tree row, no cross hedging — cutting 2 sides of the canopy, no topping (i.e. ‘hedged’). 

    5. Fall: Hedging both sides of the tree row, no cross hedging — cutting 2 sides of the canopy, no topping (i.e. ‘hedged’).

    Several measurements are collected annually to assess the effects of the pruning treatments. Highlights of 2021 results and planned 2022 measurements include:

    • –  Canopy volume was measured in May 2021. Trees boxed in spring were significantly smaller than the hand-pruned control. Trees boxed in fall or hedged in fall or spring did not differ significantly from the control.

    • –  A bark canker pathogen survey (Cytospora, Botryosphaeria, etc.) was conducted to establish a baseline of pathogens present in the field. Several canker pathogens were found, and the control treatment had the shortest canker length. A more thorough evaluation of disease presence and severity will be performed in 2022.

    • –  In 2021, a difference in severity of sunburn damage after extreme heat events was observed. The boxed treatments both had significantly less blue prune drop due to sunburn damage than the control or hedged treatments. This was surprising – fruit is typically exposed to higher light environments in the boxed trees. Though there is no definitive cause at the moment, it may be possible that bowing branches in the hedged treatments or reduced water stress in boxed trees due to smaller canopy size may have contributed. We will continue to assess these differences.

    • –  2021 treatment yields ranged between 3.0 and 4.3 dry ton marketable (A+B screens) yield per acre and no significant differences were found among the treatments in 2021 nor in cumulative yields (Table 1). Large fruit (A + B screens) comprised between 92% and 100% of the four-pound sample from all the treatments (Table 1). The spring hedged treatment did have significantly lower percentage of marketable (A+B screen) fruit than the control and fall boxed treatments.

  • California Prune Board Honors Women Across Industry

    In celebration of International Women’s Day on March 8, the California Prune Board reflected on the various women throughout the prune industry who drive continuous growth and improvement for the organization and the consumption of prunes. In critical roles including Growers, Chief Executive Officers, Researchers, and Directors, women across the prune business are shaping the decisions that define an industry.

    “Demand for California Prunes has steadily increased in the past two years and historically women have been the primary purchasers of prunes,” said Kiaran Locy, Director of Brand & Industry Communications. “The truth is prunes are enjoyed by everyone and the women in our industry are tenacious and their insights and expertise are keeping us relevant and moving us forward.”

    These 5 industry leaders within the California Prune industry, provide valuable direction and insight across a variety of professions:

    • LindaKay Abdulian is the President and CEO at National Raisin Company and has worked in the prune business for over 10 years.

    “Agriculture is a tough industry. The people involved are trenchant and as a woman in a dominant man’s world, you prepare for every encounter. The prune industry is no exception. The players are the best in the business, man, or women. You come prepared and you will succeed.”

    • Sandie Mitchell is a California Prune Grower who has been growing prunes for 44 years. She is also an Executive Committee Member for the California Prune Board

    “Women are very quality oriented. When it comes to our families, we only want the best. As a California Prune grower, we have dedicated our farming operation throughout the years to growing a premium product for the consumer.”

    • Sarah Bradley Castro is a Staff Research Associate at UC Davis and has led the prune breeding program since 2008.

     

    “I continue to be inspired by the growing number of women in agriculture and agricultural research. In my working with UC Davis, California Women in Agriculture, and the Prune Board it is clear the innovation and energy women bring to the industry will carry us forward to a successful future.”

    • Natalie Mariani Kling is the Marketing Manager for Mariani premium dried fruit and a Certified Clinical Nutritionist. As a 4th Generation Mariani, she has been working in the prune business since she could walk steadily through the orchards.

    “Working with real, whole food is an honor and a responsibility. Mother Nature is no joke, and we rely on the great women (and men) in our industry who sow their time, expertise, and commitment into growing food that families around the world can enjoy. As a nutritionist, prunes have a special place in my heart. They may be one of superfood’s best kept secrets. Watch out world!”

    • Esther Ritson-Elliott is the Director of International Marketing & Communications with the California Prune Board. She has worked with the organization for over 30 years.

    “Agriculture itself is often perceived as a ‘male’ career, yet figures published in 2017 reveal that more than one third of U.S. farmers are women, and over half of all farms have at least one female decision maker. That equates to 1.2 million female producers making a significant contribution to U.S. agricultural sales, including those working in the prune industry. I make it my mission to share the fruits of their labor, promoting the commitment, passion and contribution of our prune growers and championing their work – male and female alike.”

    Building awareness that drives consumption for California Prunes starts with a premium product and strategic approach. The California Prune industry invests in nutrition and crop research as well as building global markets for the promotion of prunes. California is the world’s largest producer of prunes and supplies over 90% of the prunes in the U.S. and 40% of the world’s production.

    The California Prune Board recognizes the extensive contributions of every woman across the industry and acknowledges the value each of them brings through their individual experiences and perspectives. These leading women in the prune industry will be featured on social media @CaliforniaPrunes on Instagram, Facebook, and Twitter and on the organization’s U.S. LinkedIn profile and European LinkedIn profile reaching consumers and the trade in honor of International Women’s Day this March.

  • CA Prune Board Advances Study of Prunes and Bone Health

    The California Prune Board (CPB) is leading the way in investigating a connection between prunes and favorable bone through a growing body of evidence spanning two decades. Building on this remarkable and extensive research, the organization is announcing recently published scientific data supporting the role prunes may play in optimal bone health, while previewing a pipeline of clinical trials currently underway.

    “The science has shown us that something unique is going on with prunes, as we’ve uncovered some remarkable connections to bone health,” said Donn Zea, Executive Director, California Prune Board. “With every study we learn something more compelling further piquing our curiosity. Our research program has more to explore, and we’re excited to see where this takes us in terms of learning more about the benefits of prunes for bone health.”

    RECENTLY PUBLISHED HIGHLIGHTS

    In a recent review paper published in Advances in Nutrition titled, “The Role of Prunes in Modulating Inflammatory Pathways to Improve Bone Health in Postmenopausal Women,” researchers from Pennsylvania State University examined the relationship between prune consumption, oxidative stress, inflammation, and favorable bone health outcomes, summarizing the results of preclinical and clinical trials. They reported that the bone-protective effects of prunes found in postmenopausal women appear to be connected to the antioxidant and anti-inflammatory activity that prunes stimulate within the body. Moreover, the authors also suggested that prunes’ favorable effect on bone may be partially explained by changes in the gut microbiota that can come from regular prune consumption.

    Additionally, in a USDA-funded clinical trial recently published in Nutrients, titled “The Short-term Effects of Prunes in Improving Bone in Men,” investigators from Florida State University sought to test the effect of daily prune consumption on bone metabolism in 35 men over the age of 50 who had some bone loss. The early findings showed a reduction in osteocalcin, a biomarker of bone turnover, and an increase in what’s known as the OPG:RANKL ratio, indicating prunes may have a positive effect on bone status after just three months of eating this whole fruit daily. These preliminary findings are a subset of a larger study with results that have not yet been published but are anticipated in the next 12-18 months.

    “As a researcher it’s exciting to see a positive change in bone turnover in these men from prune consumption after a relatively short period of time. We anticipate even more favorable results in bone status once the men have completed a full year of eating prunes every day,” said Principal Investigator Bahram Arjmandi, PhD, RDN, Professor and Director, Center for Advancing Exercise and Nutrition Research on Aging, Florida State University.

    RESEARCH UNDERWAY

    In addition to this recently published data, the following nutrition studies from highly credentialed research institutions are currently in progress and working toward completion or journal publication:

    Randomized Controlled Trial of Dietary Supplementation with Prunes on Bone Density, Bone Geometry, and Bone Strength in Postmenopausal Women

    Principal Investigator: Mary Jane De Souza, PhD – Pennsylvania State University

    With a cohort of over 200 postmenopausal women, this is the largest clinical trial to date to investigate the effect of prunes on bone status as a non-pharmaceutical plant-based strategy to combat bone breakdown.

    The Effects of 12-months of Prune Consumption on Bone Mineral Density and Bone Turnover Markers in Korean Postmenopausal Women with Osteopenia

    Principal Investigator: Peter Clifton, PhD – University of South Australia

    Co- Principal Investigator: Yoona Kim, PhD, RD, Gyeongsang National University, Korea

    This clinical trial in South Korea is the first study outside of the United States to investigate the bone protective benefits of daily consumption of prunes in Korean osteopenic postmenopausal women.

    The Impact of Consuming California Prunes on Bone Health of Young Women Using Hormonal Contraceptives

    Principal Investigator: Shirin Hooshmand, PhD, RD – San Diego State University

    The study is investigating the impact of prune consumption on bone formation and in preventing or slowing bone loss in young women 18-25 years old taking hormonal contraceptives.

    “Bone health, whether optimizing bone formation early in life or preventing bone loss in adulthood, is critical at all life stages given that the human skeleton is dynamic, undergoing a continuous cycle of building and breaking down bone,” said Andrea N. Giancoli, MPH, RD, Nutrition Advisor, California Prune Board. “We are aiming to better understand the role of prunes in this cycle that is strongly correlated to gut health, inflammation, and oxidative states within the body.”

    While it remains unclear what bioactive compounds in prunes are responsible for the beneficial effects on bone, the prune-positive bone health story may be partially due to the array of vitamins and minerals in California Prunes known to influence bone status, namely boron, potassium, copper and vitamin K. Prunes are also rich in phenolic compounds, which research suggests may inhibit bone breakdown and stimulate bone formation. Key future directions to bridge the gap in the areas of bone and the gut-bone axis are on the research horizon.

    CREATING A VISION FOR THE FUTURE 

    Advancing bone-focused nutrition research and expanding the connection to the gut-bone axis, while also exploring clinical trials in various life stages and international populations is at the heart of the California Prune Board’s strategic vision for continued research into the next decade.

    The integrity of the California Prune Board’s nutrition research program is demonstrated by the renowned research and academic institutions with whom it has partnered and the rigorous process that ensures credible research decisions.

    A top-caliber nutrition research advisory panel, led by Mary Jo Feeney, MS, RDN, FADA, FAND, helps to guide these California Prune nutrition research efforts. The panel is comprised of highly experienced researchers and nutrition experts from academic institutions, including Tufts University, Cleveland Clinic, Pennsylvania State University, University of Minnesota, and San Diego State University. This independent advisory panel provides vision and oversight of the nutrition research program and ensures scientific rigor for every project that explores the nutritional and health benefits of California Prunes.

    The California Prune Board is deeply committed to the scientific rigor of nutrition research. For more details on previously published research, visit: https://californiaprunes.org/healthy-living/benefits-of-prunes/additional-research/
