- Nutrition science researcher, Babajide Ojo at Oklahoma State University, was selected by the American Society for Nutrition (ASN) as one of five finalists to present his research at the 2016 ASN Young Minority Investigator Oral Competition. Ojo’s study investigated the effects of supplementing mangos (in the form of freeze-dried mango pulp) in mice fed a high fat diet on body composition, glucose homeostasis and gut inflammatory markers: tinyurl.com/zyz6dpc.
- Chuo Fang, PhD, of the department of Nutrition and Food Science at Texas A&M University investigated the potential role of mango and its microbial metabolites in regulating lipid metabolism and adipogenesis via the activation of AMPK in differentiated 3T3-L1 adipocytes: tinyurl.com/zwe78kq.
- Researcher Matt Nemec, of the Interdisciplinary Program of Toxicology at Texas A&M University, studied the anti-proliferative activities of pyrogallol, an intestinal microbial metabolite of gallotannin, a mango polyphenol, on mice with ductal carcinoma in situ breast cancer (DCIS): tinyurl.com/ze3y5kx.
- Vinicius Paula Venancio, of the Department of Nutrition and Food Science at Texas A&M University, studied the consumption of 300 grams of mango compared to an equivalent amount of fiber (1 teaspoon of a fiber supplement) and its effect on abdominal distention and constipation in otherwise healthy human volunteers: tinyurl.com/h6pvwnn.
Numerous compounds including vitamin C and beta carotene, as well as several polyphenolic compounds including gallic acid and their larger polymers gallotannins are contained within mangoes that have been linked to anti-cancer and anti-inflammatory activities.
The absorption, metabolism, and excretion of mango galloyl derivatives have not previously been investigated in humans. In a human pilot trial published in the journal of Molecular Nutrition & Food Research, 11 healthy volunteers between the ages of 21 and 38 years old consumed 400g/day of mango-pulp for 10 days, with blood and urine samples taken on days one and 10 of the study following mango consumption.
Participants refrained from consuming dietary supplements and foods which could be sources of gallic acid such as berries, grapes, and tea for one week prior to the beginning of the study and during the 10 days of mango consumption.
It was first necessary to study how these compounds are metabolized in the body to determine if these polyphenolic compounds have potential benefits to human health at realistic food consumption amounts.
Following 10 days of mango consumption, seven metabolites of gallic acid were identified in the urine of healthy volunteers, and of those two microbial metabolites were found to be significantly more excreted. The presence of gallic acid and pyrogallol metabolites in human urine after the consumption of 400gms of mango indicates the absorption, metabolism, and excretion of mango galloyl derivative and confirms the bioavailability of these mango-derived metabolites.
The research shows that mangoes have the potential to enhance the diet as a source of gallic acid and gallotannins, which may possess anti-inflammatory and anti-carcinogenic properties.
The National Mango Board (NMB) conducts ongoing consumer research to explore consumer awareness, knowledge about mangos, buying habits, barriers to purchase and many other factors of consumer attitudes relative to mangos. Understanding consumer purchasing behavior is key to increasing mango consumption in the U.S.
In 2013, the NMB conducted an in-depth consumer attitude and usage study to better understand consumer purchasing behaviors. The overall goal was to measure consumer awareness and usage practices as they relate to mangos, and importantly, determine the extent to which shifts have taken place over time. In addition to tracking and updating who mango consumers are, why they buy the fruit, and what might encourage future purchases, the study also investigated health awareness and health perceptions toward mangos. Results highlight that overall, providing more information and education about mangos and keeping them in front of consumers at point-of-sale (POS) and in the media would help increase mango sales. Basic education is most needed by consumers since the research reflects not knowing how to choose and select a “good” mango, as well as what to do with it after purchase.
In 2014, the NMB conducted Qualitative Exploration Research, also known as focus groups, with small groups of mango buyers and non-buyers to provide direction on effective mango messaging. The study included discussions of mango associations, usage, likes and dislikes, and the buying or eating experience and then progressed through a series of messaging statements. The statements covered general, education, nutrition and sustainability messaging. Key findings include the overall positive mango associations with tropical and sweet; with nutrition being one of the strongest messages for consumers. Top interest was paid to “100% of daily Vitamin C in a single cup,” “20 vitamins and minerals” and “100 calories a cup.” Other opportunities for mango messaging include the lack of familiarity, not knowing what to do with a whole mango, and selection and cutting.
“Consumer research is vital to focusing our marketing strategies around the obstacles and opportunities that mangos present to consumers,” stated Megan McKenna, NMB Director of Marketing. “Armed with these findings, the mango industry can move forward with its outreach regarding mango selection, ripening, cutting, and usage since they continue to be the barriers to purchase.
About National Mango Board
The National Mango Board is an agriculture promotion group, which is supported by assessments from both domestic and imported mangos. The board was designed to drive awareness and consumption of fresh mangos in the U.S. The superfruit mango contains 100 calories, an excellent source of vitamins A and C, a good source of fiber and an amazing source of tropical flavor.
Mango availability per capita has increased 53 percent since 2005 to an estimated 2.87 pounds per year in 2013. Mango import volume for 2013 was 935 million pounds.
