The many health benefits of orange juice

Tuesday, September 1st, 2015

Orange juice is the excellent source of vitamin C and fulfills the entire day requirement of vitamin C in just one serving. It is tasty and delicious with full of medicinal as well as health benefits. Orange juice is known for many minerals such as magnesium, potassium, Vitamin B6, beta carotene, calcium, folic acid, and having low fats and no cholesterol.

Folic acid in orange juice is highly beneficial for brain development and spinal cord. In a recent study, it has been found that orange juice is good for weight loss. Orange juice has other important health advantages like cardiovascular problems, diabetes, cancer and gastrointestinal disorders. The juice boosts your immunity due to the presence of vitamin C. Orange juice has the highest nutrients value among all the citrus fruits.

What are some other health benefits of orange juice? Read on.

Prevents inflammation

The modern day faulty lifestyle along with paradox in dietary pattern leads to inflammatory reactions in the body, which causes lifestyle related disorders such as diabetes, heart diseases, arthritis, asthma, depression, etc. Drinking of orange juice helps to minimize the impact of type II diabetes and atherosclerosis. The flavonoids like hesperidin, and naringenin are acting as anti-inflammatory products and good for arthritis, rheumatoid arthritis, and asthma.

Helps keep your BP in check

Orange juice is good in the management and prevention of cardiovascular disease. Orange juice contain a plant pigment called ‘hesperidin’ that is beneficial for overall the smooth functioning of  blood vessels thereby helps in balancing of blood pressure and good for cardiovascular diseases.  Drinking of orange juice decreases bad cholesterol or low density lipoprotein in the body. Bad cholesterol accounted for cardiovascular problems. The adequate amount of magnesium is good in normalizing blood pressure.

Radiant, glowing skin

Drinking orange juice is said to bring a radiant glow to your skin and provide other skin benefits as well. Drinking OJ will help to hydrate skin and keep it firm. Using this juice as a topical treatment does wonders for the skin as well. It cleans out and tightens clogged pores and is believed to prevent wrinkles and fine lines. Orange juice is also a great natural remedy for treating sunburns.

Orange juice prevent birth defects

Birth defects like low birth weight and neural tube defects can be overcome by drinking orange. The pregnant mother is suggested to take half cup of orange juice daily to fulfill the deficiency of folate, which leads to many birth related problems.

Lowers risk of heart disease

An apple a day is said to keep the doctor away, but orange juice may be good at the job, too.

An antioxidant in orange juice called hesperidin improves blood vessel function and helps lower a person’s risk of heart disease, researchers report.

Hesperidin is a plant-based compound called a flavonoid. (Grapes, red wine, green and black teas, and chocolate also contain flavonoids.) A growing body of evidence suggests that flavonoids can improve the health of the delicate cells that line blood vessels. The way these cells work is referred to as “endothelial function.” Problems with these cells can lead to the development of clogged arteries, a major risk factor for heart attacks and strokes.

For the study, 24 healthy men at risk for cardiovascular disease each drank either 500 milliliters of orange juice each day, a “dummy” drink that contained the same calories as orange juice, or a dummy drink fortified with 292 milligrams of hesperidin. A 500 milliliter glass of orange juice naturally contains 292 milligrams of hesperidin. Over the course of the study, every man drank every beverage for one month straight.

The researchers found that when the men drank the daily orange juice or the hesperidin-fortified drink, they had better endothelial function and lower diastolic blood pressure (the bottom number of a blood pressure reading) than when they drank the non-hesperidin beverage. In addition, gene expression profiles (as related to cardiovascular disease development) were improved.

Orange juice is a cancer fighter

In a recent scientific research, it has been found that orange juice contains a bio-chemical substance called ‘D-limonene’, which is effective in preventing of skin cancer, breast cancer, mouth cancer, lung cancer and colon cancer. The adequate amount of vitamin C is also good in prevention of cancer.

Orange juice treats anemia

Orange juice is one of the best sources of vitamin C that helps in the absorption of iron into the blood stream. Anemia is a disease where there is a severe deficiency of iron. Regular intake of orange juice helps the patients in this regards.

Aids in strong teeth and bones

Calcium in oranges ensures strong teeth and bone. It is also supports to maintain a healthy blood pressure level. Calcium in oranges also assists for a healthy muscle function. Carotenoids in oranges act as powerful antioxidants against harmful radicals that can damage cells. A daily glass of orange juice can help prevent the reappearance of kidney stones better than other citrus fruit juices such as lemonade.

7 Health Benefits of Drinking Organic Orange Juice

Tuesday, April 28th, 2015

You grew up drinking orange juice every morning at breakfast, but did you ever ask why? What’s so special about orange juice that makes it a staple around the world?

There are so many health benefits to drinking organic orange juice that no one could possibly name all of them. With high concentrations of vitamin C and other nutrients that are not only healthful but necessary, the orange is a super-fruit that most of us take for granted. Even if you aren’t a fan of peeling and eating sticky, juicy oranges, you can still get many of the same benefits out of a glass for breakfast each morning. If you need an extra push to start putting a jug of orange juice in your cart as you pass by the organic section on your next grocery run, check out these seven reasons to not let another day go by without adding orange juice to your diet.

1. Healing Phytonutrients: Oranges have particularly high levels of certain phytonutrients that are thought to be helpful for reducing inflammation, lowering blood pressure and balancing cholesterol! Adding a glass of organic orange juice per day to your diet can provide enough of these phytonutrients to contribute to an improvement in your overall health.

2. Daily Value of Vitamin C: We all know that we can’t function well without at least some vitamin C in our diets. It does everything from promoting strong and healthy bones and clear skin to strengthening your immune system to fight off infections and viruses. You could always take a supplement, but why do that when a delicious glass of organic orange juice provides more nutrients than vitamin C supplements with added health benefits?

3. Consuming Citrus Lowers Risk of Certain Diseases: Oranges contain many of the elements that are thought to reduce the risk of heart disease and cardiac arrhythmias, and some studies have even shown a slight reduction in the occurrence of many types of mouth, throat, esophageal, stomach and liver cancers in people who have a lot of citrus fruits in their diets.

4. Lower Cholesterol: Certain compounds in oranges are being studied as possible means to lower cholesterol. These compounds may interact in such a way with the body that they reduce its ability to produce LDL cholesterol. Lowered cholesterol then translates into a reduced risk for many types of health issues from heart disease to stroke.

5. Prevents Ulcers: Some studies have shown that people with a higher blood level of vitamin C are at less of a risk of developing peptic ulcers—a condition which can lead to stomach cancer. How do you get your vitamin C levels up? Orange juice, of course!

6. Prevents Kidney Stones: If you want to reduce your risk of developing calcium oxalate kidney stones, you may be pleasantly surprised to know that simply drinking a couple of glasses of orange juice or other citrus juice per day increases your citric acid excretion preventing kidney stones from forming.

7. Healthy Carbohydrates: For diabetics or those who are watching carb intake, you’ll be happy to know that you can still drink orange juice! Like any food, it’s important to be aware of how much you are drinking, but orange juice only has a glycemic index of 40. This means that, since it is under 55, you can drink orange juice in limited quantities to benefit from all of its nutrients—and great flavor—without having it spike your blood sugar or cause problems with weight gain.

Are you convinced? Whether you are simply looking for a healthy, nutritious alternative to a 500 calorie morning latte, or you are looking for natural ways to help reduce your risk of certain health problems, organic orange juice may be just what you need to add to your daily diet.

10 good reasons to eat an orange a day

Thursday, September 18th, 2014

Sweet and juicy to taste, orange is one of the most popular fruits in India as well as the world. Belonging to a group of citrus fruits called hesperedium, oranges have more health benefits than one. Here are the top 10 health benefits of the fruit.

1. Boosts your immunity

A single orange can meet more than 100% of your daily requirement of Vitamin C. This vital nutrient helps improve your immunity, keeping you free from diseases and infections. Here are some more immunity boosting foods.

2. Good for your skin

As we grow older, our skin along with other body parts suffers from free radical damage. This process is similar to how metals rust after exposure to air.  Even though it is inevitable, oranges are packed with antioxidants and Vitamin C which slows down the process and makes you look younger than your age! Besides oranges, you can eat these fruits and vegetables for glowing skin!

3. Great for your eyes

Along with our skin, our eyes too suffers from damage as we grow older. Oranges are rich in nutrients like Vitamin A, Vitamin C and potassium which are great for your eyes. So, if you want your vision to be just as good as it is now, eat an orange every day!

4. Prevents heart disease

One of the reasons why people get heart disease is because their arteries are blocked due to unhealthy lifestyles and consumption of junk food. Oranges have flavonoids like hesperidin which reduces cholesterol and prevents your arteries from getting blocked. This, in turn protects you from heart attack and various other cardiovascular diseases. Alternatively, you could try these 8 natural cholesterol busters.

5. Helps in brain development

Folate and folic acid present in oranges promote brain development and keep the vital organ in mint condition. In fact, these nutrients also make orange a healthy fruit for pregnant woman as it prevents the baby from having neurological disorders later.

6. Prevents cancer

Having cancer can be a tough and harrowing experience for both the patient and the caregiver. Research has shown that a compound called D – limonene present in oranges can prevent various types of cancer like lung cancer, breast cancer, skin cancer, etc. Additionally, the antioxidants and Vitamin C help promote the body’s immunity which helps in fighting cancer cells. Here are some food habits to keep cancer at bay.

7. Keeps you free from stomach ulcers

Oranges are a very good source of fiber which helps keep your stomach and intestines healthy. A diet rich in fiber will ensure that you are not affected with ailments like stomach ulcers and constipation.

8. Protects your vision

Oranges also contain very good levels of vitamin A, and other flavonoid antioxidants such as alpha and beta-carotenes, beta-cryptoxanthin, zea-xanthin and lutein. These compounds are known to have antioxidant properties. Vitamin A is also required for maintaining healthy mucus membranes and skin and is essential for vision. Consumption of natural fruits rich in flavonoids helps the body to protect from lung and oral cavity cancers.

9. Great for diabetics

People who have diabetes are unable to absorb glucose since the beta-cells present in their pancreas either fail to produce insulin or the body’s cells are unable to respond to the insulin produced. Oranges are high in fibre and have a high glycaemic index which makes it a good food option for diabetics. Also worth mentioning is that good oranges have a sweet taste, and since diabetics aren’t allowed to eat sweets or other sugary foods, they can eat oranges to tingle their taste buds.

10. Prevents hair loss

Orange has high Vitamin C content which is required for producing collagen which, in turn, is responsible for keeping the tissues in your hair together. Nobody likes bald patches on their head, and eating oranges can ensure that you do not have to part with your lovely hair as you grow older.

The Florida Department of Citrus responds to NPR story

Wednesday, September 3rd, 2014

Note: We are posting this Florida Department of Citrus rebuttal on our blog because we feel it addresses some very important issues in the “fruit juice and health” debate.

We were happy to have our voice included in yesterday’s story on NPR that described how citrus growers are managing through citrus greening and other market trends in today’s challenging environment. However, it is disappointing that the report included misinformation from Dr. Barry Popkin, a professor at the University of North Carolina, about 100% juice and health. His statement that “every study that followed people for more than a day has shown an adverse effect on cardiovascular health from fruit juice…” is simply wrong.

In reality, a considerable body of clinical and observational scientific evidence exists that supports a beneficial role for 100 percent juice – particularly orange juice – on some health or nutritional indicators, including those related to cardiovascular disease.1-5 In addition, consumption of 100% orange juice has not been associated with detrimental effects on markers of glucose or insulin metabolism, including risk for metabolic syndrome, in clinical2,6 or observational4 studies, or a recent meta-analysis7. Further, with respect to 100% fruit juice intake and weight measures:

  • Clinical studies in adults report no adverse effects on body weight or body mass index (BMI) when 100% orange juice is included as part of the diet.1,2,8
  • A systematic review of the association between 100% fruit juice intake and weight in children and adolescents reported that after assessing 21 cross-sectional and longitudinal studies, more than two-thirds of the studies found no association between 100% juice intake and adiposity – even when juice was consumed in amounts exceeding current recommendations.9
  • Epidemiological studies report no association between 100% orange or citrus juice intake and body weight, BMI, or changes in BMI over time in children or adolescents.4,10,11
  • Epidemiological studies report that 100% orange juice or 100% fruit juice consumption by adults was associated with lower body weight or BMI, or lower risk for overweight/obesity compared to no consumption.3,12
  • A comprehensive analysis published in 2014 by the Academy of Nutrition and Dietetics’ Evidence Analysis Library concluded that the evidence does not support an association between 100% fruit juice intake and weight status or adiposity in children.13

The bottom line is that these and other supportive research clearly report nutritional and other benefits of 100 percent orange juice consumption.

The health benefits of citrus

Tuesday, March 4th, 2014

Loaded with vitamins and minerals.

The vitamin C in citrus fruits acts as an antioxidant to protect cells from free radical damage. Vitamin C also improves the absorption of non-heme iron (iron from plant foods like beans and nuts). Citrus fruits supply the B vitamin, folate, which plays a role in energy production, growth and development, and may help protect against heart disease. These fruits are also a source of potassium, which is important for muscle function, and fluid and electrolyte balance.

Unique phytonutrients.

Citrus flavanones have been linked to a reduced risk of stroke in women and a reduced risk for cardiovascular disease. Liminoids in citrus fruits have been found to inhibit tumor growth. More research is needed to understand how these phytonutrients work to improve health and protect against disease. Many are found in the peel and inner white portions of the fruit, so eating whole fruits and using zest and peels as flavorings for cooking will help you get the most benefit.

Super easy snack.

There are few foods easier to grab on the go than a piece of citrus fruit. Oranges, mandarins, tangerines, and many cross-varieties are easy to pack, peel, and section for a snack. Peeling also slows you down and contributes to more mindful eating. Just remember that some citrus, such as grapefruit, can interact with prescription medications. Be sure to check with your doctor if you take medications, especially those to fight infections or treat high blood pressure, high blood cholesterol, or heart conditions.

Multiple uses.

Not only is citrus delicious by itself, but the whole fruit can be used in many meals and snacks. Homemade juices are more refreshing with fresh oranges, grapefruits, lemons, and lime. Fruit sections can be blended into smoothies. Lean meats and roasted vegetables are delicious with a splash of fresh juice and citrus zest. Dry the peels of oranges, lemons, or tangerines and add it to loose leaf tea before steeping.

Long storage.

Unlike many fruits that spoil quickly, citrus fruits have a long storage life so you can stock up when they are on sale and enjoy them throughout the season. When refrigerated, oranges and mandarins stay fresh about two weeks, lemons keep for four weeks or more, and grapefruits and limes keep even longer, often five to six weeks.

A Day in the Life of an Organic Citrus Grower

Groves, Growing, and What I Hope to Leave My Grandchildren

By Benny McLean

What’s it like to be an organic citrus grower? We sat down with Benny McLean, production manager at Uncle Matt’s Organic and Uncle Matt’s father, to find out. Benny has been a part of the citrus industry for almost 50 years, and has been an organic citrus grower for nearly a decade and a half.  Here’s what this farmer had to say about life in the groves…

A GROWER’S MORNING ROUTINE

I live in a citrus grove and I have grapefruit trees planted there. When I leave my house in the morning, I always drive through my favorite grapefruit grove.  I’ll look at the trees and ask myself questions like, “Do I have a good bloom?” “Do I have leaf drop?” “Do I see any bugs in there that could cause a problem?” It’s a daily habit for me, like getting up in the morning and eating breakfast. And the answers are out there: in the grove. All I have to do is ride the grove and the grove will tell me if there’s a problem. My dad used to say that the rising sun has the highest amount of beneficial rays for anything that grows in the soil, so if you’re going to find a problem, you’ll find it then.

FERTILIZING, FUNGUS, AND FLYERS

As an organic grower, I don’t use synthetic pesticides or fertilizers in our farm program, so observation becomes that much more important. For example, if a grove is in need of fertilizer, it will tell you by the color of the leaf.  I look for discoloration in the old flush [leaves] and discoloration in the new flush. When a tree is off-color, it might be because the trees are running low on potassium or nitrogen. Under that scenario, I’ll pull leaf samples to be analyzed and compare the lab results with what I observe. Weather patterns and leaf analysis will determine when to apply our organic fertilizer program.

In springtime, my day will also include assessing the fungus situation in the grove and its effect on the trees and fruit. At this time of year, we’re mainly concerned with Scab, Alternaria, and Melanose.  While harmless, these three conditions can prove unsightly and can knock our fruit out of grade at the packing house.  In order to boost revenue from a grove, you need a high pack-out per acre. If we find these conditions in our groves, we’ll apply organic fungicides, like beneficial bacteria, to help remedy the situation.

Pests don’t really become a problem for us until May or June.  We do have a little pest called a “rust mite.” It’s very small, but it will put a scar on the peel that will cause the graders down at the packing house to reject it. It has nothing to do with the flavor or nutritional quality of the fruit, but the rust mite scars the fruit’s appearance.

WEEDS GOING WILD

During the summer months, rain patterns in Florida really help things grow –– including weeds.  We get a lot of questions from other growers about how we control weeds since we don’t use synthetic herbicides. Honestly, we don’t obsess over weeds.  Granted, we don’t want them growing too close to the irrigation microjet emitters, so in all our groves, we’ll use weed-eaters and in-and-out mowers for weed control, as well as good, old-fashioned hand labor.  Growing up, harvesting labor crews would have come in with hoes, and saws, and clippers and they’d cut the vines and hoe up the bad weeds and all of that. They’d work through the hot, Florida summer. Yet, some of today’s farmers don’t even know what a hoe is. Their only reaction is to spray weeds with herbicides.

My father always told me you have to look at it two ways. He said if you got an orange tree growing in your yard and you have beautiful St. Augustine grass growing under the orange tree, you could say, “Oh my, that orange tree is getting all the fertilizer and water from my beautiful grass, so I’ve got to do something about that orange tree.” The next guy comes by and says, “Oh my, that grass is taking all the fertilizer and water away from the orange tree. I’ve got to do something about that grass.” My dad would say, “You know what? They’re compatible. They exist with each other. They get along.” The exception would be what we call a “reset,” such as a small one-year old tree. It’s then that the weeds are a major problem. But a mature tree actually produces shade that doesn’t allow for weeds to grow well under its canopy anyway.

FRUIT PICKIN’ TIME

In late fall, when harvest is right around the corner, I begin to look for signs of fruit maturity. There are state-mandated maturity guidelines for harvesting based on minimum levels of brix [fruit sugar], juice, and ratio. Until the fruit meets all three of these criteria, we can’t pick it. Every variety has its own standards. After meeting the maturity levels, we’ll look at size because there are minimum size requirements as well. So, you’ll find us out in the groves with our calipers measuring fruit size as harvest time (November through May for various varieties), gets closer.

What’s funny is that it’s the buyer who decides what the right size is. The fruit falls into five different categories, with one being too small and the other, too large. So, it’s the middle three sizes that a buyer typically wants. The homemaker doesn’t have a choice when going to the supermarket. When I give grove tours, many women will see some of my biggest grapefruit and ask why they can’t buy that in the store. Well, now you know!

BEING A DIE-HARD ORGANIC FARMER

At the end of the day, I love growing organically. I have eleven beautiful grandkids and I know I am creating something worthwhile for their longtime health if they are going to eat citrus.  I believe I am educating them on how to read the label, so to speak. They can make intelligent food choices based on the knowledge of how a food was grown, how it was processed and how it was stored. I know what it is to be a conventional farmer, and I know the difference eating organic can make in your health. As long as I have a choice, I’ll never go back with all that I’ve learned and observed over the past 14 years of being an organic farmer. I believe that organic is the better choice.

A Quick Q&A with “Papaw” McLean

UM: What’s your favorite citrus variety?

Papaw: Ruby Red Grapefruit

UM: What’s your favorite tractor?

Papaw: A big green one with citrus implements

UM: How do you like your grapefruit eaten?

Papaw: “Sectionized.”

UM: Favorite breakfast?

Papaw: Fresh organic grapefruit from my grove, 4 ounces of cottage cheese, and a handful of raw organic almonds

UM: What legacy do you want to leave your grandkids?

Papaw: I want them to understand that it’s the three L’s. #1: You got to love life. #2 You’ve got to love the land. #3 You’ve got to love the Lord. And if you can understand those three principles, you’ll carry this legacy onto the next generation.

UM: In your opinion, what’s the best reason for someone to try organic for the first time?

Papaw: I know that organic is a healthier source of citrus juice –– orange, tangerine, grapefruit. I know that it has a higher antioxidant level than any of the other juices. If you’re going to drink orange juice because it’s healthy, then choose the healthiest one.

Uncle Matt’s Juices: Just What the Doctor Ordered!

Friday, January 25th, 2013

With this decade’s worst cold and flu season in full swing, it’s good to know that Mother Nature provides natural ways to fight back. Adequate vitamin C intake is key to shortening the duration of sickness, and juices high in vitamin C will help get you there fast. In fact, the right 100% fruit juices should be an essential part of your diet when you have a cold to shorten its duration and get you back to full health.

And we’re happy to announce that Uncle Matt’s Organic orange and grapefruit juice make the list for “Best Cold-Fighting Juices.”  They are both excellent naturally-derived sources of vitamin C. And what’s more, all of Uncle Matt’s juices are U.S.A.-grown without the use of synthetic pesticides and herbicides.

One 8 oz. serving of orange juice provides 154% of the daily-recommended intake of vitamin C, while 8 ounces of grapefruit juice provides 134%. Both juices supply 1% of zinc, an essential mineral proven to boost immunity.

So besides stocking up on Uncle Matt’s orange and grapefruit juices during your next bout with the flu, consider this healthy fact: drinking plenty of cold liquids, like grapefruit and orange juice, can also help relieve a runny nose, according to Joanne Larsen, MS, RD, LD.

100% Orange juice consumption is associated with better diet quality, improved nutrient adequacy, decreased risk for obesity, and improved biomarkers of health in adults

Thursday, January 24th, 2013

Consumption of 100% orange juice (OJ) has been positively associated with nutrient adequacy and diet quality, with no increased risk of overweight/obesity in children; however, no one has examined these factors in adults. The purpose of this study was to examine the association of 100% OJ consumption with nutrient adequacy, diet quality, and risk factors for metabolic syndrome (MetS) in a nationally representative sample of adults.

One Hundred Percent Orange Juice May Play an Important Role in Supporting Intake of Certain Underconsumed Nutrients

BARTOW, Fla., Oct. 25, 2011 /PRNewswire via COMTEX/ — Orange juice may do more for children’s diet and overall health than you think, according to results of a recently published study in Nutrition Research.

Data from this study suggest children (ages 2-18 years) who drink 100 percent orange juice tend to have improved nutrient adequacy and diet quality, as well as certain diet and health parameters.(1) Additionally, the research suggested that consumption of 100 percent orange juice was not associated with overweight or obesity in children.

As part of the study, researchers analyzed data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) and found that children who regularly consume 100 percent orange juice tended to have significantly higher intakes of vitamin C, potassium, vitamin B6, folate, dietary fiber and magnesium than non-consumers. None of the children who consumed 100 percent orange juice were below the Estimated Average Requirement (EAR) for vitamin C, while nearly 30 percent of non-consumers were below the EAR. Furthermore, diet quality (as measured by the Healthy Eating Index (HEI-2005)) was significantly higher in those children consuming 100 percent orange juice than in non-consumers, as was intake of total fruit, fruit juice and whole fruit.

“A growing body of research has painted a clear picture that enhanced nutrient intake and better diet quality are associated with drinking 100 percent orange juice in children,” said study co-author Carol E. O’Neil, PhD, MPH, LDN, RD, School of Human Ecology, Louisiana State University Agricultural Center. “Our research adds further support to the association between drinking 100 percent orange juice and higher intakes of five important nutrients–vitamin C, folate, magnesium, dietary fiber and potassium–which are generally underconsumed by the U.S. population.”(2)

This is the first study that has examined the usual intake of 100 percent orange juice in a nationally representative population, and these data add support to previous studies that found no association between 100 percent fruit juice consumption and increased risk for overweight and obesity in children and adolescents. Furthermore, children who consumed 100 percent orange juice had significantly lower mean LDL cholesterol levels than those who did not consume 100 percent orange juice.

“These findings are consistent with the Dietary Guidelines for Americans, 2010, which conclude that ‘for most children and adolescents, intake of 100 percent fruit juice is not associated with body weight,'”(2) said Gail Rampersaud, MS, RD, LDN, Associate in Nutrition Research and Education, University of Florida. “It’s encouraging that the overall body of research provides evidence to support children enjoying all of the taste, nutritional and health benefits that 100 percent orange juice offers.”

Relation to Dietary Guidelines for Americans, 2010

According to the Dietary Guidelines for Americans, 2010, the “total diet” should consist of nutrient-dense foods that provide essential nutrients and health benefits.

“People can feel good about enjoying one hundred percent orange juice daily because it fits many of the key recommendations outlined in the Dietary Guidelines,” said Rampersaud. “For example, 100 percent orange juice is more nutrient-dense than many commonly-consumed 100 percent fruit juices, and one 8-ounce serving is a good source of potassium and folate, as well as an excellent source of vitamin C.”(3)

Editor’s Note: The National Health and Nutrition Examination Survey (NHANES) is an ongoing series of surveys, implemented by the Centers for Disease Control and Prevention, that are designed to assess the health and nutritional status of children and adults in the United States. The NHANES surveys are conducted and analyzed in a way to be representative of the U.S. population. The analysis published in Nutrition Research used 2003-2006 data from more than 7,200 children and adolescents.

Decrease of Blood Pressure with Regular Consumption of Orange Juice

Tuesday, August 30th, 2011
Source: American Journal of Clinical Nutrition

Blood pressure is the amount of force required for the heart to circulate blood through the body. Systolic blood pressure represents the maximal blood pressure during systole, and diastolic blood pressure the minimum pressure at the end of ventricular diastole. Arterial blood pressure can be defined hemodynamically as the product of cardiac output and total peripheral resistance. Cardiac output is the main determinant of systolic pressure while peripheral resistance largely determines the level of diastolic pressure. Hypertension is a cardiovascular disease characterized by elevation of blood pressure above arbitrary values considered normal for people of similar racial and environmental background. Hypertension affects the vasculature of all major organs (heart, brain, kidneys), and myocardial infarction and congestive heart failure account for the majority of deaths secondary to hypertension.

A study published in the American Journal of Clinical Nutrition investigated the effect of orange juice and its major flavonoid, hesperidin, on blood pressure and cardiovascular risk biomarkers. The study included 24 healthy, moderately overweight men who were randomized to consume either 500 mL orange juice, or 500 mL hesperidin or 500 mL placebo drink for four weeks. The results revealed that diastolic blood pressure was significantly lowered after four weeks consumption of orange juice or a hesperidin drink when compared to the placebo drink. It was also determined that orange juice and hesperidin significantly improved post-meal blood vessel reactivity compared with placebo. These results appear to suggest hesperidin may contribute to the beneficial effects of orange juice, which may reduce diastolic blood pressure and increase post-meal blood vessel reactivity.1
