Health Benefits of Freshly Squeezed Orange Juice

Nature has generously enriched oranges with valuable vitamins and minerals for the human body. Thanks to its composition, citrus has diverse therapeutic properties:

• Activates metabolism;
• Supports proper functioning of internal organs and systems;
• Protects against infections;
• Absorbs fats and toxins in the intestines;
• Serves as a preventive measure against cancer.

In folk medicine, fresh juice is used as a general tonic, pain reliever, diuretic, anti-inflammatory, antibacterial, and anti-edema remedy.

Orange juice is also popular in cosmetology. In homemade face masks, it gently cares for the skin: refreshes, tones, brightens, slows aging, and in scrubs and wraps — reduces cellulite. Orange juice is also used for seborrhea, hair loss, and to promote hair growth and health.

For Women

The previously listed benefits of orange juice apply to both men and women.

Specific benefits for the female body:

• Stimulates steroid hormone production, normalizes hormonal balance;
• Delays the onset of menopause;
• Supports reproductive system functions;
• Alleviates menopausal symptoms — such as headaches, irritability, weakness, excessive sweating, and hot flashes;
• Boosts immune defense;
• Prevents premature aging;
• Improves blood circulation in the pelvic organs;
• Enhances libido.

During Pregnancy

During pregnancy, orange juice is recommended as an additional source of micro- and macroelements, vitamins essential for the health of both mother and baby. The presence of folic acid is particularly valuable. This vitamin is crucial for fetal development. Its deficiency can lead to neural tube defects in the child or spontaneous abortion.

Orange juice also provides vitamin B2, which contributes to the physiological formation of fetal tissues and organs, and vitamin E — regulating placental development according to the baby’s needs.

While Breastfeeding

A nursing mother’s diet should be optimal for the child and balanced in nutrients. Orange juice contains a complex of micro- and macroelements, minerals, amino acids, and omega-3s necessary for the baby’s growth and development, as well as the mother’s health.

However, since citrus is an allergen, it should be introduced gradually. Excessive consumption may cause bloating, colic, or jaundice in newborns, especially in the first 2–3 months.

For Men

Men often follow healthy eating principles less strictly, consuming fewer fruits and vegetables, which can lead to health issues. Nutritionists advise regular orange juice consumption for men of all ages. It saturates the body with vitamins, minerals, amino acids, polyphenols, and other beneficial compounds that support immune, nervous, endocrine, urinary, cardiovascular, and digestive health.

Specific benefits for men’s health:

• Prevents urological diseases, prostatitis, or eases their course, reducing complications.
• Thiamine, along with vitamins A and C, improves pelvic blood flow, minimizes prostate congestion, and supports natural erectile function.
• Zinc and selenium stimulate testosterone production, crucial for sexual health, libido, and muscle development.
• The vitamin-mineral complex strengthens immunity and nervous system function, as chronic stress and infections impact reproductive health.
• Acts as a powerful aphrodisiac, enhancing sexual desire and attractiveness.

For Children

Orange juice benefits children of all ages, especially during active growth. It is a natural source of calcium, essential for bone development and tooth mineralization. The fruit also contains proteins vital for cellular function and muscle tone.

B vitamins enhance brain activity, regulate growth hormone, and improve metabolism. Vitamin PP, along with other components, strengthens immunity, protecting against flu and respiratory infections.

Orange juice supports vision, accelerates wound healing, aids skin and hair health, and promotes nail strength.

For the Elderly

With age, cardiovascular risks increase. Preventive measures include a healthy diet rich in fruits and vegetables. People over 30–40 should include fresh orange juice in their diet.

Vitamin C plays a key role:

• Strengthens immunity;
• Supports thyroid and pancreatic function;
• Stimulates bile production;
• Maintains capillary integrity;
• Lowers cholesterol, preventing atherosclerosis;
• Stabilizes high blood pressure.

Other components also benefit seniors: retinol slows aging, calcium maintains bone density, and B vitamins reduce dementia risk and stress effects.

Applications of Fresh Orange Juice

Thanks to its rich vitamin-mineral profile, orange juice benefits both men and women at any age. It aids in weight loss, disease prevention, and protection against infections. For best results, combine juice therapy with a balanced diet and healthy lifestyle.

Note: Freshly squeezed orange juice is far more beneficial than whole fruit, as it absorbs quickly (within 10–20 minutes) with minimal digestive strain, and its energy is fully utilized for tissue repair.

In Cosmetology

Orange juice enhances attractiveness by improving skin health:

• Tones and hydrates;
• Promotes even skin tone;
• Reduces pigmentation;
• Prevents wrinkles;
• Stimulates hair growth;
• Reduces cellulite by improving circulation.

For Weight Loss

Orange juice aids weight loss due to its low caloric value (40 kcal per 100 ml) and high nutrient content.

Key benefits for weight management:

• Polyphenols suppress appetite and prolong satiety.
• Pectin detoxifies, improves digestion, and accelerates fat breakdown.
• Vitamins C, K, PP regulate metabolism.
• Retinol boosts endurance, encouraging fat burn.
• Citrus stabilizes blood sugar, easing pancreatic load.

Its diuretic and choleretic effects further support weight loss by reducing bloating and constipation.

Note: Orange juice enhances any diet when paired with proper nutrition and exercise.

In Folk Medicine

Traditional uses of orange juice include:

1. Cardiovascular health: Strengthens vessels, prevents atherosclerosis, and regulates blood pressure.
2. Anemia treatment: Iron and vitamin C improve hemoglobin levels.
3. Brain function: B vitamins enhance cognition and reduce stress.
4. Detoxification: Cleanses liver and intestines.
5. Kidney support: Acts as a diuretic, reducing edema.
6. Antioxidant effects: Lowers cancer risk by neutralizing free radicals.
7. Bone health: Eases arthritis and osteoporosis symptoms.
8. Immunity boost: Protects against seasonal illnesses.

Potential Harm and Contraindications

Orange juice contains acids that may irritate the digestive tract. It is contraindicated for people with gastrointestinal disorders, gastritis, or ulcers. Those with high stomach acidity, citrus allergies, or sensitive tooth enamel should consume it cautiously.

Oranges are strong allergens. Overconsumption may trigger skin reactions. If symptoms appear, discontinue use and consult an allergist.

How to Drink Orange Juice Properly

General guidelines:

1. Dilute concentrated juice with water or another juice (1:1).
2. Use room-temperature distilled water.
3. Drink immediately (within 20 minutes) or store in a sterilized glass jar in the fridge for up to a day.
4. Avoid metal utensils when juicing to prevent acid reactions.
5. Use a straw to protect tooth enamel, then rinse your mouth.

Daily Intake

For detox and health benefits, adults should drink at least 600 ml daily. To avoid overloading the liver and kidneys, limit intake to 1 liter per day.

Can You Drink It on an Empty Stomach?

Never drink orange juice on an empty stomach. It disrupts gut flora and may cause digestive discomfort. Those with GI conditions may experience worsened symptoms. Always consume it after meals.

Tip: To protect your stomach lining, take 1 tbsp of olive oil before drinking juice.

Conclusion

The benefits and harms of orange juice depend on the fruit variety, cultivation methods, and preparation. Choose freshly squeezed juice over pasteurized commercial versions for maximum nutrients. Regular consumption supports overall health, prevents diseases, and aids recovery.
