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
Do you want to live another decade? A new study shows a plant-rich diet can add 10 years to your life.
The study, published in PLOS Medicine, examined a diet which was heavy on fruits, vegetables, beans and grains. According to the models, a 20-year-old who went all-in on the plant-based diet could add 10 years to their life. Even just making a partial change could add six years of life expectancy. And, an 80-year-old who started a plant-based diet could add three years to their life.
The study was conducted by scientists at the University of Bergen, Norway, and titled “Estimating Impact of Food Choices on Life Expectancy: A Modeling Study.
“A sustained dietary change may give substantial health gains for people of all ages both for optimized and feasible changes. Gains are predicted to be larger the earlier the dietary changes are initiated in life,” according to the study authors.
Like the Alliance for Food and Farming’s popular residue calculator, which clearly and visually shows consumers how safe their favorite fruits and vegetables are, the study authors created their own calculator, Food4HealthyLife, where users can calculate how dietary changes can impact their life expectancy.
This new study complements decades of research that verifies consumption of fruits and vegetables prevents diseases, boosts immune function, promotes better health, improves cognition and increases lifespan. It is worth noting that most of these positive health studies were conducted using conventionally grown produce.
The overwhelming nutritional benefits of a produce-rich diet and the equally impressive science showing the safety of all fruits and vegetables is why consumers should ignore efforts by certain groups who attempt to discourage consumption of popular produce items by using inaccurate and inflammatory safety claims.
With only one in 10 of Americans eating enough each day, according to a new analysis from the Centers for Disease Control, consumers should be urged to eat whatever produce they enjoy and is accessible and affordable for them. Organic and conventionally grown – both are safe and can be eaten with confidence.
Let science be your guide and don’t let anyone or any group discourage you from eating the fruits and vegetables you prefer.
Higher walnut consumption may be associated with a lower risk of death and an increase in life expectancy among older adults in the U.S., compared to those who do not consume walnuts.
A new study conducted Harvard T.H. Chan School of Public Health researchers, has been supported by the California Walnut Commission.
“What we’ve learned from this study is that even a few handfuls of walnuts per week may help promote longevity, especially among those whose diet quality isn’t great to begin with,” Yanping Li, Senior Research Scientist at the Department of Nutrition at Harvard T.H. Chan School of Public Health, and lead investigator of this research.
“It’s a practical tip that can be feasible for a number of people who are looking to improve their health, which is top of mind for many people,” Li said.
This study found five or more one-ounce servings of walnuts per week may provide the greatest benefit for mortality risk and life expectancy.
Eating five or more servings per week was associated with a 14% lower risk of death (from any cause), a 25% lower risk of dying from cardiovascular diseases, and a gain in about 1.3 years of life expectancy, compared to those who didn’t consume walnuts.
Consuming walnuts two to four times per week could have its benefits, too, with the study finding a 13% lower risk of death overall, 14% lower risk of dying from cardiovascular diseases, and a gain in about one year of life, compared to non-walnut consumers.
Participants were relatively healthy when they joined the studies and were followed for about 20 years (1998-2018).
Dietary intake was assessed every 4 years in which participants reported on their overall dietary intake – including how often they consumed walnuts, other tree nuts, and peanuts – as well as lifestyle factors like exercise and smoking status.
Based on this data, the researchers were able to identify associations between walnut consumption at varying levels and different health indicators related to longevity.
As a prospective observational study, these results do not prove cause and effect, but they do shed light on how walnuts may support an overall healthy lifestyle that promotes longevity.
Participants who consumed greater amounts of walnuts tended to be more physically active, have a healthier diet, lower alcohol consumption, and take multivitamins.
All of these factors could influence life expectancy, however, the researchers adjusted for these aspects in their analysis. In addition, it’s important to note that this data was collected before the current Covid-19 pandemic.
One ounce of walnuts is a powerhouse of important nutrients for optimum health, including protein (4g), fiber (2g), a good source of magnesium (45mg) and an excellent source of the essential omega-3 ALA (2.5g).
Bakersfield, CA based Country Sweet Produce’s Bako Sweet line of sweet potatoes are now certified by the American Heart Association’s Heart-Check Food Certification Program just in time to celebrate American Heart Month and National Sweet Potato Month this February.
As shoppers look for healthier, but still tasty ways to incorporate fresh foods into their diets this year, sweet potatoes remain top of mind. Not only are they heart-healthy, but they have also taken center stage as a gluten-free alternative thanks to Whole30 influencers who brought us sweet potato toast and Vegan influencers who made sweet potatoes the star of so many plant-based dishes. Just last month, Bako Sweet’s Organic Sweet Potato Steam Bags won the Eat This, Not That 2022 Food Award for Best Healthy Starchy Side.
To celebrate National Sweet Potato Month this month, Bako Sweet is hosting a Grown With Love giveaway on its Instagram page from Feb. 1 – 28, where people have the opportunity to win a year of free sweet potatoes, a heart-shaped Le Creuset dish, and their new “sweet potato lovers” swag. Last year the brand hosted a similar giveaway and saw more than 5,000 participants.
Bako Sweet offers a library of heart-healthy recipes that also work well for Superbowl and Valentine’s Day, including:
“Sweet potatoes are such a fun food and their nutritious benefit is hard to beat since they are rich in Vitamin C, potassium, and loaded with fiber,” said Whitney Stuart, dietitian and diabetes educator at Whitness Nutrition. “A sweet potato is the perfect high-fiber compliment to any meal since they can be used for sweet or savory dishes.”

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.”
Adolescence is a critical period for the evolution of cardiometabolic risk factors that are largely influenced by diet and lifestyle. Understanding these risk factors is essential to developing effective dietary guidance for disease prevention targeting this critical age period. Recently published research in the British Journal of Nutrition found that 9-17 year-old girls who consumed up to one cup of potatoes daily had no increased risk of becoming overweight or developing high blood pressure, dyslipidemia, or impaired fasting glucose by the end of the study in late adolescence.
According to the 2020-2025 Dietary Guidelines for Americans, girls aged 9 – 18 are encouraged to consume 1½ to 3-cup equivalents per day of vegetables, depending on their calorie needs, but most fail to meet these guidelines. In this study, the highest levels of potato consumption ranged from 1/5 to 1 cup per day and at that level, no adverse effects were observed.
“Our results show that nutrient-rich potatoes can be part of a healthy diet in young girls during this important period of growth and development,” says Lynn L. Moore, DSc, MPH, Boston University, the study’s senior author. “There is growing evidence that overall diet quality is what really matters in the preservation of heart health. Potatoes are an affordable food, with a number of valuable nutrients, and our research suggests that moderate intakes of potatoes, along with many other types of vegetables, can be a regular part of a healthy diet pattern.”
Higher intakes of all forms of potatoes (including fried) during the ‘tween’ years of nine to 11 were associated with higher intakes of potassium and dietary fiber, two nutrients of public health concern, [i] as well as vitamin C, vitamin B6 and magnesium. Black girls in this study with the highest intakes of potatoes also consumed more fruit and non-starchy vegetables and had higher diet-quality scores.
Study Design, Strengths and Limitations
The researchers analyzed data from nearly 2,000 subjects (approximately 50% Black, 50% White) from the National Growth and Health Study, a longitudinal study of the development of obesity and other cardiovascular-related outcomes in adolescent girls.
- For girls at 9-11 years of age, researchers analyzed data on total potato intake (white and sweet) as well as separate intakes of fried and non-fried potatoes.
- For girls at 9-17 years of age, researchers analyzed data for total potato intake (white and sweet).
Diet was assessed using 3-day diet records at baseline when girls were 9-10 years old, and during the follow-up years 2-5, 7, 8, and 10. The intake of potatoes (both white and sweet potatoes) was extracted from total vegetable servings. Anthropometric measures of body fat and body composition and blood pressure were measured annually. Additionally, fasting triglycerides, other lipids, and glucose were measured in later adolescence (at 18-20 years of age)
Repeated measures of a number of potential confounding variables were examined, including socioeconomic status, body mass index (BMI), changes in height, physical activity, television viewing, intakes of food groups and nutrients, as well as diet quality measured by the Healthy Eating Index (HEI)-2015. The study’s strengths include its prospective design as well as the use of multiple sets of three-day diet records, which is considered the gold standard method for dietary assessment. Researchers also took repeated measures of cardiometabolic risk factors and most potential confounders.
The investigators acknowledge limitations to the study, such as reliance on self-reported dietary intakes from adolescents who may have had difficulty accurately estimating portion sizes and reporting details. However, parents and other caregivers were actively involved in the completion of these diet records, especially during the earlier years of the study. Researchers were unable to assess the effects of very high levels of potato intakes since few girls reported consuming more than one cup equivalent of potatoes per day. They were also unable to analyze any differences between white and sweet potato consumption, given the low intakes of sweet potatoes within the study population. Finally, the researchers were unable to control for baseline values of fasting glucose or triglycerides due to missing or unreliable data at the initial exam.
This study was selected as the Nutrition Society’s Paper of the Month. Every month, the Editors-in-Chief of the Nutrition Society’s journals select one paper as being of particular interest or originality, and/or because it challenges previously conceived notions in nutritional science and public health. The research manuscript, “Potato consumption is not associated with elevated cardiometabolic risk in adolescent girls,” is published in the British Journal of Nutrition (https://doi.org/10.1017/S0007114521003445). Authors include Ioanna Yiannakou, Mengjie Yuan, R. Taylor Pickering, Martha R. Singer, and Lynn L. Moore, Boston University. In addition to funding from the National Institutes of Health, funding was provided by the Alliance for Potato Research and Education (APRE); APRE had no input on interpretation of the results or manuscript development.
Canadian company Execulytis Consulting reports growth will be largely driven by those under 25 years old increasing their purchasing power.
Likewise, Category Partners of Idaho Falls, ID notes more product availability and the narrowing price gap between organic and conventional produce items is also spurring the market. This price gap has gradually narrowed over time due to more product being available. This will continue to put downward pressure on prices in the future.
A recent Execulytics Consulting survey of 5,000 Canadian grocery shoppers found 39% of consumers under 25 (Generation Z) say organic is always their preferred choice or that they only buy organic products. This compares with 25% of those over 25 saying the same.
This survey revealed consumers under 25 have shown an interest in more specialty products including mangoes, limes and Asian vegetables, and this could provide a growth opportunity for such products. At the same time, they have purchased fewer bananas, apples, potatoes and strawberries than their older counterparts. While this younger age group is not fully in the marketplace yet, they will increase their purchasing power and thus drive growth of organic produce in the future.
During the pandemic, consumers moved toward products they perceived as providing a safer way to obtain food naturally, and this positively affected the organic market.
This perception of safety also gave a boost to packaged produce products. In the past, retailers have been focused on the number of unique items they carry, but the current labor shortage has put pressure on those offerings, which in turn has affected the number of unique organic items retailers can offer.
Carlson Produce Consulting of Chicago notes while the organic market has experienced double-digit growth in the past, that growth has slowed, saying the category is maturing.
However, the growth of indoor farming will boost the segment, and CPC reports there is significant opportunity for indoor farming to grow. The company reports the availability of product on a 52-week basis will be key to driving growth of specific items including blueberries. With this increased availability the market could get a boost from items that aren’t typically the highest drivers of sales.
Category Parnters notes unique salad blends coming out of urban greenhouse environments will drive growth as consumers are discovering those products, and they come with a higher retail price.
During the third quarter of 2021, total organic sales dollars increased by 3.4% compared with the same quarter of the previous year, according to the Organic Produce Network, Category Partners and Nielsen. This compared with a third quarter of 2020 that was influenced by pandemic-driven shopping. Conventional produce dollars increased by 1.3% in comparison. Berries, apples and packaged salads accounted for 85% of all organic fresh produce dollar growth during the third quarter. Berries specifically grew in sales dollars by 11% during the quarter.
In the future the growth of the segment will not be limited by demand but by supply. When consumers are surveyed, they indicate they believe organic produce is superior in every way, indicating a larger share of consumers will act on that preference as more options become more affordable.
Category Partners observes it is not a question of consumer demand, but supplier capabilities and grower capabilities.
During the third quarter of 2021, organic produce represented 12% of the total produce market in the U.S. and it is conceivable the organic segment could gain another 10 percentage points of growth over the next 10 years.

All-yellow flesh potatoes continue to rise above russets, reds and whites in the critical metric of retailer volume sales, an encouraging sign for grocers as growers ready for their upcoming fall harvests.
In the last 52 weeks ending June 13, 2021, retailer volume sales of all-yellow flesh potatoes are up 9.56%, far outpacing reds (up 0.82%), russets (down 3.91%) and whites (down 8.42%) according to the research firm IRI.
Over a broader timespan, 2021 retailer profits from all-yellow flesh varieties to date represent 11.3% of the potato category, up from 8.8% in 2017.
“There continues to be huge growth potential with the all-yellow flesh varieties, particularly among younger, more health-conscious millennial shoppers looking for a flavorful potato side dish,” says Andreas Trettin, director marketing for MountainKing.
Trettin adds MountainKing has witnessed similar growth trends with its popular all-yellow flesh varieties packaged as Butter Russets, presenting the look of a traditional russet; Butter Golds with their yellow and smooth skin; and its oval-shaped Butter Reds.
All three varietals, he explains, offer a creamy, smooth texture and a rich, natural buttery flavor requiring fewer ingredients and toppings.
“The feedback from consumers, across the board, is that the all-yellow flesh varieties offer a better taste when compared to regular russets and reds,” Trettin says. “What we’re seeing is really an evolution in cooking styles with the routine and conventional giving way to creativity and adventure.”
MountainKing Potatoes is one of the world’s largest growers of high-flavor potato varieties.
If you’ve dipped your toes into plant-based eating, you’re probably familiar with meat substitutes such as lentils, beans, tofu, tempeh, and seitan. They each tend to shine in different recipes — beans and lentils lend themselves well to veggie burgers, for instance, and tofu shines in stir-fries. But when you’re trying to replicate the texture of pulled pork or another shredded meat, jackfruit reigns supreme.
What Is Jackfruit?
Jackfruit is a tropical tree fruit usually grown in Asia, Africa, or South America, per the Cleveland Clinic.
As an ingredient, jackfruit can be used in both sweet and savory dishes, but people typically use it as a meat substitute. Jackfruit tends to take on the flavors of the spices and sauces you cook it with. “Its texture, similar to that of shredded meat, makes it a good meat substitute for the vegetarian and vegan population,” says Kristin Gillespie, RDN, a Virginia Beach–based nutrition support dietitian for Option Care Health and an advisor for Exercise With Style.
You can find different versions of jackfruit at the grocery store. “The ‘meat’ of the fruit is available in fresh, canned, or dried versions,” says Bonnie Taub-Dix, RDN, the New York City–based author of Read It Before You Eat It: Taking You From Label to Table.
Some Notes on Cooking With Jackfruit
Replacing meat with plants offers several health benefits. When compared to conventional diets, plant-based diets have a positive effect on weight, metabolism, and inflammation, according to a September 2019 systematic review published in the journal Translational Psychiatry. People who follow a healthy plant-based diet tend to eat higher amounts of nutrient-rich foods, including whole grains, fruits, vegetables, nuts, and legumes, according to an August 2019 research article published in the Journal of the American Heart Association. These foods are rich in potassium, magnesium, iron, vitamin A, vitamin C, and folate, and they’re lower in saturated fat and cholesterol than the foods typically found in a meat eater’s diet. Per the 2019 research article, plant-based diets have been shown to reduce the risk of cardiovascular disease, cardiovascular disease mortality, and mortality in general. They may also lower body mass index, blood pressure, HbA1C levels, and cholesterol levels, according to other past research.
Just keep in mind that jackfruit doesn’t have as much protein as meat. “Three and a half ounces of jackfruit supplies 1.7 grams (g) of protein, whereas animal protein like fish or poultry gives about 21 g for a similar portion size,” Taub-Dix says. “Unlike animal protein, however, jackfruit has no cholesterol or saturated fat.”
Jackfruit is also mainly carbohydrate-based, so keep that in mind if you’re trying to lose weight. “Since jackfruit contains nearly 40 g of carbs per cup, you’ll want to watch your portion size and the foods you pair with the fruit,” says Kelsey Lorencz, RDN, with Graciously Nourished in Saginaw, Michigan.
You might be intimidated by the look of this giant, prickly fruit, but it’s a worthy addition to your plant-based diet.
Children who eat more fruits and vegetables have better mental wellbeing, according to new research from the United Kingdom’s University of East Anglia Health and Social Care Partners.
The study shows that eating more fruit and vegetables is linked with better wellbeing among secondary school (middle to high school age) pupils in particular. What’s more, the research showed U.K. children who consumed five or more portions of fruit and vegetables a day had the highest scores for mental wellbeing.
The study was led by UEA Health and Social Care Partners in collaboration with Norfolk County Council, according to a news release.
Public health strategies and school policies should be developed to ensure that good quality nutrition is available to all children before and during school to “optimize mental wellbeing and empower children to fulfil their full potential,” researchers said.
“While the links between nutrition and physical health are well understood, until now, not much has been known about whether nutrition plays a part in children’s emotional wellbeing,” lead researcher Professor Ailsa Welch, from UEA’s Norwich Medical School, said in the release.
“So, we set out to investigate the association between dietary choices and mental wellbeing among schoolchildren.”
The research team studied 2017 data from almost 9,000 children in 50 schools across Norfolk (7,570 secondary and 1,253 primary school children) taken from the Norfolk children and Young People’s Health and Wellbeing Survey, according to the release. Children in the study self-reported their dietary choices and took part in age-appropriate tests of mental wellbeing that covered cheerfulness, relaxation, and having good interpersonal relationships, the release said.
The study found only around a quarter of secondary-school children and 28% of primary-school children reported eating the recommended five-a-day fruits and vegetables. What’s more, the study found that just under one in 10 children were not eating any fruits or vegetables.
The research team also looked at the association between nutritional factors and mental wellbeing and considered other factors that might have an impact – such as adverse childhood experiences and home situations.
“We found that eating well was associated with better mental wellbeing in children,” Richard Hayhoe, also from UEA’s Norwich Medical School, said in the release. “And that among secondary school children in particular, there was a really strong link between eating a nutritious diet, packed with fruit and vegetables, and having better mental wellbeing.”
