Answer:
Oranges, lemons, and grapefruits are called "super fruits" because they offer numerous benefits. They are rich in nutrients, have a cooling effect, and effectively help the body regulate temperature. They should be included in your daily diet. All three fruits contain high levels of water, abundant vitamin C, antioxidants, flavonoids, and essential minerals. These nutrients help quench thirst, boost the immune system, support recovery after illness, improve resistance, and protect the skin from aging.
Additionally, oranges, lemons, and grapefruits can be easily processed into refreshing drinks like smoothies and juices. Daily consumption aids digestion thanks to their fiber content, balances electrolytes, and reduces fatigue.
In traditional medicine, oranges are known for their sweet and slightly sour taste, cooling properties, and ability to clear heat, resolve phlegm, and cleanse the lungs. An average orange provides about 70-90 mg of vitamin C, boosting immunity and providing strong antioxidant effects. Oranges are also rich in potassium, folate, and flavonoids, which support cardiovascular health, lower bad cholesterol, and combat inflammation.
Orange juice is an ideal choice for summer days. It can be mixed with carrot or apple juice, or a pinch of salt can be added to make it easier on the stomach. However, limit consumption to 200 ml/day to avoid excess acid. Pregnant women can drink more but should divide the intake throughout the day, while children should only consume half an orange daily. People with gastric or duodenal ulcers, pancreatitis, or kidney disease should avoid oranges. Additionally, avoid eating oranges on an empty stomach, immediately after a full meal, or close to the time of drinking milk to prevent indigestion.
Grapefruits are notable for their rich vitamin C content – just half a fruit meets 50% of the daily requirement – along with high levels of vitamin A and fiber. These nutrients help boost immunity, promote quick recovery from colds and flu, and protect the body from free radicals. Grapefruit also aids in weight loss due to its low calorie count and fiber that provides a feeling of fullness.
Eating grapefruit directly or juicing it offers refreshment, and adding honey can enhance the flavor.
Lemons have a high vitamin C content (about 30-50 mg/fruit), which helps boost resistance, supports digestion, reduces bloating, and balances stomach acid. They're also rich in antioxidants, helping maintain skin moisture, reduce fatigue, and replenish electrolytes on hot days. Diluted fresh lemon juice with warm water is an inexpensive and easy-to-make drink, ideal for cooling down.
