Step aside, kale—there’s a new superfood on the scene. Agriculture and nutrition experts have recently identified the healthiest vegetable on Earth.
The CDC assigns nutrition density scores to produce based on their concentration of essential vitamins and minerals. Usual suspects like spinach, chard, and beet greens all have scores ranging in the 80s. But the only vegetable to earn a perfect score of 100 is watercress.
“What’s watercress?” you may ask. This leafy green is part of the Brassicaceae family and grows in bodies of fresh water, like streams and ponds. It’s closely related to cabbage, kale, radishes, and mustard. Its scientific name, Nasturtium officinale, translates from Latin as “nose twister.” And if you’ve ever taken a bite of the mature leaves, you know why.
The “Eat Healthy and Live Green” campaign launched recently by
The Peruvian Avocado Commission, aims to inspire consumers to embrace a healthier lifestyle that’s good for them and the planet.
The commission is promoting the myriad health benefits of avocados, believing it is important to driving demand.
McDaniel Fruit Company of Fallbrook, CA strongly supports the work of the Peruvian Avocado Commission’s marketing strategy focusing on the health benefits of avocados. It notes these efforts, in tandem with the Hass Avocado Board’s Avocado Nutrition Center research, help elevate the category for all avocado growers, packers and shippers and pave the path for continued growth in the category.
In addition to the trend in healthier eating, the Vancouver, B.C.-based Oppy of Vancouver, B.C. sees the versatility of avocados fueling demand.
The company sees awareness growing about the different ways to consume avocados, and this boost in demand will require supply from its current regions and beyond.
One big question is with rising food inflation, will consumers continue to purchase as many avocados?
Oppy admits it is hard to tell, admitting there’s absolutely a correlation between price and demand.
Since avocados are recommended as an item in the produce aisle with some of the most nutritional benefits, many view it as an important ingredient in their daily diet. This is why Oppy doesn’t see avocados being affected by inflation that much. So, while they may not be recession-proof, they are likely to be less price sensitive.
Watermelon is a unique fruit with compounds that may have health effects throughout the body, supporting normal cardiovascular and metabolic health, a new study has found.
According to a new comprehensive review of the scientific literature on watermelon, eating watermelon regularly may help promote health. This research paper, authored by Britt Burton-Freeman, Ph.D., and colleagues from Illinois Institute of Technology was recently published in the journal Current Atherosclerosis Reports.
“Research is unveiling the health-promoting potential of watermelon. The current literature review provides evidence that watermelon intake and citrulline supplementation lower blood pressure in human trials. Although more research is needed, favorable effects on lipids/lipoprotein metabolism are emerging based on the data we reviewed and reported in preclinical models,” said lead author Burton-Freeman.
According to the research, watermelon contains essential vitamins, minerals, antioxidants and amino acids. It also contains the amino acids citrulline and arginine, which both act as a precursor to nitric oxide, a molecule that plays a role in blood pressure regulation, lipid reduction and glucose control. Polyphenols and carotenoids, particularly lycopene, are also abundant in watermelon.
The nitric oxide benefits of citrulline and arginine coupled with the bioactivity of polyphenols and carotenoids found in watermelon suggests that this fruit may support normal cardio-metabolic health.
Burton-Freeman and colleagues reviewed the preclinical and clinical trial evidence published from 2000 to 2020 to assess watermelon intake and citrulline (a signature compound found in watermelon) on cardiovascular and metabolic outcomes, and to identify future directions important for establishing dietary guidance and recommendations.
They explored studies related to the whole fruit as well as citrulline supplementation, focusing on key cardio-metabolic risk factors. More research is needed to confirm findings of the studies identified in this literature review.
The investigators concluded that watermelon provides a combination of nutrients and phytochemicals working across multiple mechanisms to induce biological effects. Citrulline and arginine are central to these cardio-metabolic effects, and polyphenols, lycopene, potassium and magnesium contribute as well.
Continued research is needed to determine the level of sufficient intake for clinical outcomes and will also need to be studied in a variety of populations. Research on the whole fruit and its products (i.e., juice) is also needed to help determine the level of sufficient intake.
The research identified additional potential benefits from watermelon consumption that warrant further research, such as body weight control (possibly through satiety mechanisms), glucose control, and brain and gut health.
Low fruit intake is one of three dietary factors associated with death from cardiovascular disease (CVD) and type 2 diabetes (T2DM), as are high salt intake and low whole-grain intake. These dietary factors affect people regardless of age, sex and other socio-demographic variables.1 Recent research also shows that eating a variety of fruit helps reduce the risk of T2DM2, while the amount of fruit and the type of fruit selected provide cardiovascular benefits

Fresno, CA – A new clinical study published in the scientific journal Nutrients found that consuming grapes significantly increased the diversity of bacteria in the gut which is considered essential to good health overall. Additionally, consuming grapes significantly decreased cholesterol levels, as well as bile acids which play an integral role in cholesterol metabolism. The findings suggest a promising new role for grapes in gut health and reinforce the benefits of grapes on heart health.
In the intervention study[1], conducted at the University of California, Los Angeles, and led by principal investigator Zhaoping Li, M.D., Ph.D., healthy subjects consumed the equivalent of 1.5 cups of grapes[2] per day – for four weeks. The subjects consumed a low fiber/low polyphenol diet throughout the study. After four weeks of grape consumption there was an increase in microbial diversity as measured by the Shannon index, a commonly used tool for measuring diversity of species. Among the beneficial bacteria that increased was Akkermansia, a bacteria of keen interest for its beneficial effect on glucose and lipid metabolism, as well as on the integrity of the intestinal lining. Additionally, a decrease in blood cholesterols was observed including total cholesterol by 6.1% and LDL cholesterol by 5.9%. Bile acids, which are linked to cholesterol metabolism, were decreased by 40.9%.
“We found that grapes have a beneficial effect on gut bacteria, which is great news, since a healthy gut is critical to good health,” said Dr. Li. “This study deepens our knowledge and expands the range of health benefits for grapes, even as the study reinforces the heart health benefits of grapes with lowered cholesterol.”

The recently released Harvard study on the health benefits of eating nuts just confirmed what health conscious consumers already know, that nuts are good for you, reports The NPD Group, a leading global information company. NPD’s food market research finds that nuts rank among the top 10 snack-oriented convenience foods for U.S. consumers motivated by health and weight needs.
Nuts are a popular snack for breakfast and morning snack but are eaten throughout the day by health and weight conscious consumers who want a nutritious, natural, better-for-you snack, according to NPD’s Snacking in America report, which examines long-term attitudes and behaviors about snacking as well as snack selection drivers. Consumers who are motivated to choose nuts and other better-for-you snacks based on health and weight needs tend to be seniors and empty nesters, adult females, and higher income households.
The consumption of nuts is not limited to the health and weight conscious. Seventy-seven percent of U.S. households have nuts or seeds on-hand and 19 percent of individuals eat nuts at least once in a two week period, finds NPD. Nuts are consumed primarily as an in-home snack but are often incorporated into morning, lunch, and dinner meals. In addition to its choice as a healthier snack, nuts are also popular among consumers looking for a filling or a quick, convenient snack.
“Whether to meet the needs of the health and weight conscious or as an easy grab-and-go snack, nuts are a popular choice among snackers,” says Darren Seifer, food and beverage industry analyst. “Food manufacturers and retailers have a variety of options and audiences for marketing nuts.”
A frequently expressed concern in the ongoing public health debate is the lack of affordability of fresh vegetables, especially those that are nutrient dense. A new study, “Vegetable Cost Metrics Show That Potatoes and Beans Provide Most Nutrients Per Penny,” published in the journal PLOS ONE, shows that potatoes are one of the best nutritional values in the produce aisle, providing one of the better nutritional values per penny than most other raw vegetables and delivering one of the most affordable source of potassium of the more frequently consumed vegetables, second only to beans.
Dr. Adam Drewnowski and colleagues from the University of Washington used a combination of nutrient profiling methods and national food prices data to create an “affordability index,” which was then used to examine the nutrients per unit cost of 98 individual vegetables as well as five vegetable subgroups including dark green, orange/red, starchy, legumes (beans and peas) and “other” vegetables.
The results indicated while dark green vegetables had the highest nutrient density scores, after accounting for cost, starchy vegetables (including potatoes) and beans provided better nutritional value for the money. Potatoes, in particular, provide one of the lowest cost options for four key nutrients including potassium, fiber, vitamin C and magnesium. Among the most frequently consumed vegetables, potatoes and beans were the lowest-cost sources of potassium and fiber—nutrients of concern, as identified by the 2010 USDA Dietary Guidelines.
“The ability to identify affordable, nutrient dense vegetables is important to families focused on stretching their food dollar as well as government policy makers looking to balance nutrition and economics for food programs such as the school lunch program and WIC,” said lead researcher Adam Drewnowski, PhD. “And, when it comes to affordable nutrition, it’s hard to beat potatoes.”
The study was funded by the United States Potato Board and adds to the growing database of nutrition science that supports potatoes in a healthful diet. In addition, one medium-size (5.3 ounce) skin-on potato contains just 110 calories per serving, boasts more potassium (620g) than a banana (450g), provides almost half the daily value of vitamin C (45 percent), and contains no fat, sodium or cholesterol.

Field trials and genetic studies have shown that a new variety of broccoli reliably yields higher levels of a health-promoting compound.
Broccoli contains a compound called glucoraphanin, which has been shown to promote health by maintaining cardiovascular health and a reduction in the risk of cancer. A long term breeding program to increase glucoraphanin levels has resulted in the commercial release of Beneforté broccoli. Beneforté was developed by crossing standard broccoli with a wild relative derived from Sicily.
Publicly funded research to develop Beneforté broccoli was led by two of the UK’s world-leading biological research institutes: the Institute of Food Research and the John Innes Centre, on the Norwich Research Park. They both receive strategic funding from the Biotechnology and Biological Sciences Research Council (BBSRC).
Three years of field trials at over 50 different sites in Europe and the United States have shown that Beneforté broccoli consistently produces 2-3 times the amount of glucoraphanin than other leading varieties of broccoli, without affecting yield, quality or the levels of other nutrients.

- “The Ambrosia apple variety has a creamy flesh and wonderful taste …right up there with Royal Gala and Braeburn. This apple doesn’t oxidize or turn brown quickly so it’s a nice ingredient for your favourite fruit salad!” says Pete Luckett, host of the Food Network’s show The Food Hunter.
- Although Ambrosia is a sweet apple, official taste comparisons have proved that even the most ardent fans of tart apples will be won over by its juiciness and crunchy texture.
Ambrosia is a low-acid apple, which makes it easier for kids and older people to digest.
- Once you have purchased Ambrosia apples, you should store them in the refrigerator crisper to ensure that they retain their flavor and texture.
- Three medium Ambrosia apples equal about 450g (1lb). One medium apple yields about 175ml (3/4 cup) of sliced apples.
- In an article written for the Vancouver Province newspaper, Stephen Wong, a leading Vancouver food consultant and chef, rated the Ambrosia 9 out of 10 for texture, juiciness, flavour, and general attributes.
- Ambrosia apples are now being grown by farmers in North America, Europe, Chile and New Zealand, and are available to purchase in stores around the world.
- In order to extend their availability beyond harvest time, Ambrosia apples are “put to sleep” in Controlled Atmosphere (CA) storage. CA storage takes cold storage a step further by lowering the temperature and the oxygen levels, so fruit can be stored for six months or more and remain harvest fresh.
- Ambrosias, like other apples, are loaded with health giving properties such as pectin, a cholesterol-lowering soluble fibre, and anti-oxidants, which are good for preventing heart disease.
- The original Ambrosia apple tree was grown from a chance seedling. Commercially viable chance seedlings are extremely rare; less than a dozen of these chance seedlings have found their way to market in the past 50 years.
- Ambrosia means “food of the gods” as depicted in ancient Greek mythology. The name was chosen by Wilfrid Mennell, who, with his wife Sally, discovered the original Ambrosia apple tree in their orchard in the Similkameen Valley of British Columbia.
- When first introduced to the public at the annual Apple Festival in Vancouver, British Columbia, Ambrosia met with instant acclaim and has been a favourite of the Festival ever since.
Besides being one of the better priced items in your produce deparment this year, a new study touts the benefits of eating kiwifrut..
Kiwifruit have long thought to be a nutritional powerhouse. But a new nutritional analysis published in the peer reviewed journal Nutrition Today further verifies that fact. The author of the paper, Dr. Keith Singletary, Professor Emeritus of Nutrition at the University of Illinois, found that in addition to its antioxidant benefits, kiwi fruit can also help the digestive tract and even your skin.
“Potential benefits include a rich source of antioxidants, improvement in gastrointestinal laxation, lowering of blood lipids, and alleviation of skin disorders,” as stated in the published paper titled, “Kiwifruit: Overview of Potential Health Benefits.”
The Nutrition Today paper stated that kiwifruit is also a rich source of vitamin C as well as folate, potassium and dietary fiber. The paper cited ongoing, preliminary research that is investigating other possible health benefits associated with kiwi consumption. “The fruit’s content of nutrients and biologically active phytochemicals has stimulated investigations into its antioxidant and anti-inflammatory actions that might then help prevent cardiovascular disease, cancer and other degenerative disorders.”
The California kiwifruit growers, as a member of the International Kiwifruit Organization (IKO), partnered with other kiwifruit growers around the world in conducting the research that further affirms these known potential nutritional benefits of consuming kiwifruit.
California represents 98% of U.S. kiwifruit production or about one-third of all the fresh kiwifruit supplies in the United States during the season. California farmers produce up to eight million trays of the nutritious fruit from September to May with its primary production in October and November. As domestic production from California has increased, kiwifruit has become an increasingly popular fruit for Americans.
The 2012/13 crop is well on its way into the growing season and the mild summer weather California has experienced thus far is sure to promote good size and great flavor.
