With the arrival of winter, the days become shorter and the temperature drops, which means cold and flu are on the horizon, often leading to frequent doctor visits. So, what should we eat to boost and improve our immunity to combat flu and cold this winter? Dry fruits and seeds, honey, hot beverages (tea, soup, and broth), protein-rich diets (eggs, meat, chicken, and fish), leafy vegetables, and seasonal fruits are the frequently consumed options to protect against seasonal illnesses. Among these options, juicy, sweet, and tangy oranges stand out as a superb choice. They are rich in Vitamin C, a powerful antioxidant, and are also considered the KING OF IMMUNITY BOOSTERS because they can reduce the duration of illness, enhance iron absorption, and increase white blood cell production and function, all of which help in fighting infections.
NUTRITIONAL VALUE OF ORANGES
Oranges provide a wide range of nutrients, including thiamine, folate, Vitamin A, Vitamin C, potassium, fibers, calcium, magnesium, carbohydrates, protein, sugar, no sodium, and a small amount of fat.
Thanks to this impressive mix of nutrients, oranges are uniquely equipped to help the body fight infections and stay healthy during winter. Let’s check out,
ORANGES AS IMMUNITY BOOSTER
Nature has produced delicious oranges in winter specifically to boost immunity and fight infections, thanks to the presence of superstar nutrients like Vitamin C, flavonoids, and carotenoids.
ORANGES’ IMPACT ON FLU AND COLD
To understand their effects more clearly, let’s explore the impact of oranges on flu, cold, and sore throat by answering some frequently asked questions.
DAILY INTAKE OF ORANGES WILL SOMEONE FROM GETTING FLU AND COLD? IS IT FACT OR FICTION?
With regular intake of oranges, the risk of catching flu and cold becomes lower. However, it is important to note that it will not assure complete prevention.
TANGY ORANGES WORSEN THE FLU AND COLD? IS IT TRUE?
Contrary to some beliefs, oranges strengthen the immune system because of their high Vitamin C content and other health-promoting nutrients. In fact, they support recovery from cold and flu by reducing the duration of illness and alleviating the severity of symptoms.
AND WHAT ABOUT SORE THROAT?
However, acidic fruits such as citrus fruits (oranges are less acidic compared to lemons and limes in the citrus family), due to their citric acid content, can further irritate an already inflamed throat lining. Therefore, for sore throats, less acidic fruits are the best option.
WHICH IS BETTER FOR IMMUNITY ORANGES AS A WHOLE FRUIT OR AS JUICE?
Because of added sugar, orange juice is not a healthy option for improving immunity, as sugar suppresses the immune system. Consequently, it is better to enjoy whole oranges as a fruit this winter to gain maximum health benefits, thanks to their natural fiber content and lack of added sugar.
OTHER HEALTH BENEFITS OF ORANGES
Magical, health-supporting oranges may play a critical role in overall well-being by enhancing or boosting the immune system. Beyond flu and cold prevention, let’s explore their other remarkable benefits.
• SUPPORT HEART HEALTH
Oranges support heart health due to the following reasons:
1. High potassium content and low sodium in oranges are beneficial in lowering blood pressure and supporting heart health.
2. Vitamin C, the star nutrient for immunity and antioxidant protection, reduces oxidative stress and inflammation, promoting vascular health by preventing atherosclerosis (through protecting LDL from damage that may lead to plaque formation).
3. Hesperidin and naringenin are bioflavonoids that reduce the risk of coronary artery disease and stroke.
4. High water content in oranges improves blood circulation by maintaining blood volume and viscosity (thickness of blood).
5. Fiber in oranges helps reduce blood cholesterol levels.
Taken together, these benefits show why oranges are more than just an immunity booster they actively support cardiovascular health.
• PROMOTE EYE HEALTH
How can oranges improve eye health? What magical nutrients do they contain?
An orange a day may help keep age-related macular degeneration (AMD) away. Here’s how:
1. Vitamin C is required for collagen production and maintenance of the cornea.
2. High water content in oranges prevents eye dryness.
3. Vitamin C supports blood vessels in the cornea for good vision. By reducing oxidative stress, inflammation, and free radical formation, it subsequently improves vision.
4. Vitamin C lowers the risk of age-related eye diseases such as macular degeneration and cataracts.
5. Flavonoids in oranges also support eye health by improving blood circulation in the tiny blood vessels of the eye.
In fact, according to a study published in the American Journal of Clinical Nutrition, one serving of oranges per day could lower the risk of late-stage AMD (15 years later) by more than 60%.
• ORANGES FOR DIGESTIVE HEALTH
How are oranges beneficial for optimal digestive health? The answer lies in their composition:
Oranges support digestive health due to the presence of soluble and insoluble fiber and high-water content. These factors help relieve constipation by softening and adding bulk to stool. Insoluble fiber promotes healthy gut microbes, which also positively impact brain health. Soluble fibers reduce cholesterol absorption from the intestine and help lower blood cholesterol levels.
• BRAIN HEALTH
Age-related cognitive decline and memory loss are significant health issues. Interestingly, diets rich in fruits and vegetables have been linked to improved brain health. Let’s check out how oranges contribute:
1. Vitamin C, a powerful antioxidant and anti-inflammatory nutrient, reduces oxidative stress and inflammation, protects brain cells from damage, and provides neuroprotection against cognitive decline and neurodegenerative diseases such as Alzheimer’s.
2. Flavonoids (phytochemicals) in oranges improve blood flow, support signaling pathways, and enhance memory and learning.
3. Thiamine and folate further boost brain health chemistry.
Overall, several studies support the positive link between oranges and brain health, showing improvements in cognitive function, alertness, memory, and learning.
• IMPACT OF ORANGES ON SKIN HEALTH
Oranges support skin health due to Vitamin C, which is essential for collagen production. Vitamin C and flavonoids fight free radicals, protect the skin from damage, reduce age-related wrinkles, and maintain skin elasticity. Oranges also help skin glow by hydrating it and exfoliating dead skin cells, brightening the complexion, and minimizing acne risk.
• INFLAMMATION AND ORANGES
Thanks to antioxidative and anti-inflammatory nutrients like Vitamin C, flavonoids, and carotenoids, oranges help combat chronic inflammation, which is a major risk factor for diabetes, cancer, arthritis, and cardiovascular disease.
• AID IN IRON ABSORPTION
As discussed in previous articles, Vitamin C enhances iron absorption. Therefore, apple juice with one or two oranges can be a superb drink against iron-deficiency anemia.
• SUPPORT BONE HEALTH
The bone-supporting nutritional profile of oranges including Vitamin C, potassium, magnesium, and calcium may assist in improving overall bone health.
THE BOTTOM LINE
In conclusion, enjoy delicious, juicy, and tangy oranges this winter to overcome flu and cold while reaping numerous health benefits. Nature has produced oranges in the winter to support our well-being and good health.
FAQs ABOUT ORANGES AND IMMUNITY
