Orange juice ‘improves brain function’

Wednesday, July 12th, 2017

A small study, which saw 37 adults with an average age of 67 consume 500ml (just under a pint) of orange juice daily for eight weeks, found they had an 8% overall improvement in cognitive function compared with a group who consumed a control drink.

At the beginning and end of the eight weeks their memory, reaction time and verbal fluency was measured by carrying out eight tests.

One of the tests of verbal memory required learning a list of words to be recalled immediately, and again after a 30-minute delay.

Researchers said an 8 per cent improvement equates to remembering one more word from a shopping list of 15 items. Small improvements such as this over an eight-week period could translate into substantial improvements over the lifespan.

While the researchers are not recommending that people drink 500ml of orange juice every day, due to its high sugar content, they said their findings show that the constituents of orange juice could play an important role in providing brain-boosting nutrients as part of a healthy, balanced diet.

Co-author Dr Daniel Lamport, of the University of Reading’s School of Psychology and Clinical Language Sciences, said orange juice is a major source of a group of naturally occurring plant phytochemicals known as flavonoids, and is particularly rich in a subclass of flavonoids, known as flavanones.

Recent studies have shown that flavonoids may improve memory through the activation of signalling pathways in the hippocampus, a part of the brain that is associated with learning and memory.

He said with a rapidly ageing population and estimations that the number of persons aged 60 or over could triple by 2100, it is “imperative” that simple, cost-effective ways to improve cognitive function in old age are explored.

“Small, easily administered changes to the daily diet, such as eating more flavonoid-rich fruits and vegetables, have the potential to substantially benefit brain health,” he said.

“We know that people find it difficult to sustain big changes to their diet but simple alterations are much easier to maintain permanently.

“More research on the positive effects of flavonoids on cognition is still needed. However, this is an important discovery which strengthens the growing body of evidence that flavonoid-rich foodstuffs could play a big role in tackling cognition decline in old age.”

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.
