New study indicates avocado consumption may be associated with better diet quality

Positive health indicators also associated with avocado consumption

IRVINE, Calif. (February 20, 2013) & New analysis of data from the National Health and Nutrition Examination Survey (NHANES) , a program of the Centers for Disease Control and Prevention (CDC), indicates that consuming avocados may be associated with better diet quality and nutrient intake level, lower intake of added sugars, lower body weight, BMI and waist circumferences, higher "good cholesterol" levels and lower metabolic syndrome risk. These results were published in the January 2013 issue of Nutrition Journal.

Specifically, the survey data (NHANES 2001-2008, 17,567 U.S. adults ages 19 years and older) revealed that the 347 adults (50% female) who consumed avocados in any amount during a 24-hour dietary recording period had several significantly better nutrient intake levels and more positive health indicators than those who did not consume avocados. Among the avocado consumers, average daily consumption was about one half (70.1 /- 5.4 g/day) of a medium sized avocado, somewhat higher in male avocado consumers (75.3 /-6.3 g/day) than females (66.7 /- 7.3 g/day).

Overall Diet Quality, Energy and Nutrient Intakes

  • According to the study, Avocado consumers more closely adhered to the Dietary Guidelines for Americans than those who did not eat avocados, as measured by the Healthy Eating Index (HEI).
  • Avocado consumers had significantly higher intakes of certain important nutrients including 36% more dietary fiber, 23% more vitamin E, 13% more magnesium, 16% more potassium and 48% more vitamin K than non-consumers.
  • Avocado consumers also had significantly higher intakes of "good" fats (18% more monounsaturated and 12% more polyunsaturated) and total fats (11% more) than non-consumers, although average caloric intake of both groups was the same.
  • Avocado consumers and non-consumers had similar intakes of sodium.

Physiological Health Measures 

  • Avocado consumers had significantly lower BMI values than non-consumers.
  • Avocado consumers had significantly smaller waist circumference measures than non-consumers (an average of 4 cm smaller).
  • Avocado consumers weighed significantly less than non-consumers (an average of 7.5 pounds less).
  • Avocado consumers had significantly higher HDL ("good") cholesterol levels.

Metabolic Syndrome Risk

The study found that Avocado consumers had a 50% lower odds ratio for metabolic syndrome compared to non-consumers. Metabolic syndrome is a name given to a group of risk factors which, when they occur together, increase the risk for coronary artery disease, stroke and type-2 diabetes.

As with most analyses of NHANES data, research findings were based on cross-sectional data from a single 24-hour dietary recall (which may be inaccurate and biased due to misreporting and memory lapses) and cannot provide cause and effect evidence between avocado consumption and improvements in diet quality. "These findings suggest an interesting association between the consumption of avocados and better nutrient intakes and other positive outcomes," said study primary investigator Victor Fulgoni, PhD. "These observations were derived from population survey data, they provide important clues to better understanding the relationships between diet and health, and give direction to future research endeavors."

"To this end, the Hass Avocado Board is funding additional clinical studies to investigate the relationship between fresh avocado consumption and risk factors for cardiovascular disease, avocados' potential positive role in weight management and diabetes, and avocados' ability to enhance nutrient absorption," said Hass Avocado Board Executive Director Emiliano Escobedo.

New avocado research makes superfruit even more desirable

New Zealand researchers have discovered thatNew Zealand-grown avocados have unique nutritional qualities, with double the amount of vitamin B6 and 20 percent more folate than those grown in other countries. Demand for avocados is already surging in New Zealand and this nutrient packed superfruit is fast becoming a staple ingredient in the diets of high-performance athletes, busy parents and the elderly. The findings were announced at the New Zealand Avocado 2017-18 season launch held at Eden Park’s Centenary lounge  on Wednesday 9 August. The launch drew celebrities and included presentations from head international rugby strength and conditioning coach, ironman and avocado grower Nic Gill, and chef, author and avocado enthusiast Nadia Lim. New Zealand Avocado Chief Executive Jen Scoular says the new research is huge news for the nation. “We always knew avocados were good for us. It’s wonderful that we have now confirmed our locally grown fruit is especially healthy.” New Zealand avocados have a folate measurement of 81.6 ug* per 75g serving, providing 41 percent of the recommended daily intake.  They have a vitamin B6 measurement of 0.47mg per 75g serving, providing 30 percent of the recommended daily intake. Folate contributes to normal growth and development in children, and to good tissue growth in pregnancy. Vitamin B6 contributes to normal immune system function and helps reduce fatigue. But that’s not all - the superfruit is fullof healthy mono-unsaturated fats that help keep appetites under control, is low in sugar and sodium, a good source of dietary fibre, and is packed with a range of essential vitamins and minerals. These vitamins are particularly beneficial for athletes, mums, busy families and young professionals. Nic Gill, who is also an associate professor of Sport and Recreation at AUT, addressed the guests on achieving optimal performance.  Gill is credited by the likes of Jeff Wilson and Steve Hansen as being the key architect behind the best-conditioned team in the world. Avocados are “the Ferrari of fruit.” “Many athletes and high performing individuals eat avocados throughout the day, due to the nutrient dense and quality fuel they provide,” says Gill Celebrity chef and co-founder of My Food Bag, Nadia Lim, demonstrated healthy ways of using avocados at the launch, and spoke about the need to innovate for a healthier New Zealand. “Avocados are simply one of the best everyday simple, healthy delicious foods and Kiwis love learning new ways to enjoy them.” Nadia prepared for guests two salads; roast pumpkin, pear, avocado salad with blue cheese and raspberry balsamic dressing and harissa chicken, pumpkin and avocado salad with mint yoghurt dressing.  Launch guests included Art Green and Matilda Rice, Laura McGoldrick, Mikki Williden, Zac Franich and Viarni Bright who were served five different avocado dishes to enjoy. The latest research was conducted by the Phytochemical and Health team at Plant & Food Research throughout the 2015-16 season. New Zealand avocados were analysed in accredited laboratories in New Zealand following the protocols required by the New Zealand Food Composition Database, NZFCD. NZFCD is an independent validated source for the nutritional composition information for the foods consumed by New Zealanders. ug* is the correct symbol for the metric measurement microgram which is one millionth of a gram or one thousandth of a milligram.

Biosecurity preparedness for the avocado industry

Biosecurity preparedness for the avocado industry NZ Avocado is seeking industry feedback on the intention to sign the Brown Marmorated Stink Bug (BMSB) Operational Agreement (OA).  Just like the Fruit Fly OA, this is a threat specific arrangement under the Government Industry Agreement (GIA) biosecurity partnership. All horticulture groups were asked to undertake research to determine if they will be impacted by the arrival of BMSB into New Zealand. NZ Avocado has now completed this assessment and believes that we would be a minor beneficiary for the collective readiness and response activities that industries and MPI will undertake. Although the threat to avocados is believed to be minimal there remains a number of unknowns as BMSB has not yet invaded some of the major avocado producing areas of California so the investigation into the bugs potential to impact avocados continues.  The conclusion of the NZAGA Executive is that we should be part of the BMSB Operational Agreement. However, as the impact to avocados is minimal we have negotiated a very lowimpact rating and proportionate cost share (0.2%) with a well-defined fiscal cap. This ability to fix an industry’s financial liability through the Operational Agreement process is one of the main advantages of joining GIA.  With over 150 BMSB interception events in the 2016-17 risk period (September to April), this invasive bug has a high potential of invading NZ in the coming years. Through the GIA partnership we would want to help mitigate the impact of BMSB as they will also be a significant household nuisance for growers.

On The Way To Meet Audacious Goals - Growers Rewarded With Record New Zealand Avocado Season

The New Zealand avocado industry has just reported its highest value ever with avocados sales reaching $198 million, an increase of $64 million on last season and $62 million higher than the previous record of $136 million in 2013-14. Volume too was a record 7.7 million trays in the 2016-17 season - an 84% increase on last season. The season saw significant increases in demand across all markets, with Australia remaining the industry’s largest market with an almost insatiable consumer demand. Over 70% of New Zealand avocados are exported with the remaining avocados sold in New Zealand. New Zealanders too are finding more and tastier ways to use avocados, and starting to add them regularly to their shopping basket. Jen Scoular, Chief Executive of NZ Avocado, says the industry’s Primary Growth Partnership programme: NZ Avocados Go Global, has provided a major boost to the sector. "We are part of an industry that has gone from $70 million in value in 2013 to an impressive $200 million in 2017. The Go Global programme gave us the platform as an industry to develop a strategy with audacious goals of quadrupling sales and trebling productivity in ten years. That strategy, and Crown investment has been implemented and resulted in fantastic growth in value right across the supply chain” says Scoular. "The independent review of the NZ Avocados Go Global programme said the five-year programme had made a major contribution to the New Zealand avocado industry,” says Scoular. "The review noted that we’ve achieved a step change in the way the industry operates and it’s now a much more trusting, collaborative, cohesive, communicative and co-ordinated industry, with a correspondingly greater public profile.” Alistair Petrie, Chair of the Avocado Exporter Council said, "We saw a superb increase in demand that was matched by excellent planning and supply from harvest through to delivery to customers in market. Versatility, health benefits and the amazing taste of avocados are the key drivers for that demand.” Ashby Whitehead, Chair of NZ Avocado, says the industry is in the best state it has been for many years. "With the huge increase in value from avocados and much higher visibility of the global opportunities, we are seeing strong growth throughout the industry. Demand for new trees has resulted in a near trebling of production at nurseries, large commercial investors in Northland are converting dairy farms to avocado orchards and smaller orchards are maximising the productivity of their orchards. Growers will be very happy with their returns and are looking at further investment. It’s a very exciting time to be in the New Zealand avocado industry.”
