火龍果為什麼是健康的?

What is dragon fruit?

The dragon fruit looks like a pink oval with green scales. Inside there is white pulp and tiny black seeds.

This is a tropical fruit that comes from the prickly pear cactus and is found all over the world, but it is native to Mexico and South America.

Dragon fruit season is from summer to early autumn. It comes in many shapes and colors:

  • Pink skin, white flesh. This is the most famous one, but the least sweet.
  • Pink skin, red or pink flesh. This variety is larger and sweeter than its white-fleshed cousin.
  • Pink skin, purple flesh.
  • The skin is yellow and the flesh is white. Yellow dragon fruit is the hardest to find, but also the sweetest.

Dragon fruit nutrition

Is dragon fruit healthy? According to the United States Department of Agriculture (USDA), 1 cup of dragon fruit contains:

  • 103 calories.
  • 0 grams fat.
  • 5.6 grams of fiber.
  • 27.4 grams of carbohydrates.

Health Benefits of Dragon Fruit

The pulp of dragon fruit is low in calories and contains no fat. Dragon fruit benefits also include:

It is a good source of fiber

Dragon fruit is an excellent source of fiber. The recommended daily fiber intake for adults is at least 25 grams, and dragon fruit contains 5.6 grams of fiber per 1 cup.

Fiber may benefit gastrointestinal and cardiovascular health, and fiber also has a filling effect, which is helpful if you're trying to lose weight. People who eat whole foods rich in fiber are more likely to maintain a healthy weight.

It may improve your gut health

Healthy bacteria in your gut may aid digestion and even reduce colorectal cancer risk. Dragon fruit is a prebiotic that promotes the growth of the probiotic bacteria Lactobacillus and Bifidobacterium.

Some studies seem to suggest that dragon fruit promotes the growth of healthy gut bacteria, which may have a positive impact on the gut microbiome (the good bacteria in our guts).

It is rich in antioxidants

Dragon fruit contains several different types of antioxidants that neutralize free radicals. These free radicals can damage cells and cause inflammation, which can lead to chronic diseases such as cardiovascular disease, diabetes and even cancer.

Vitamin C is an antioxidant that helps your body absorb iron and promotes a healthy immune system. Carotenoids may reduce cancer risk. Lycopene is a carotenoid that may improve heart health and reduce cancer risk.

    當我哋講「鐵質」時,唔止係話有冇攝取足夠,而係講緊鐵喺人體內唔同形態(尤其係三價鐵 Fe³⁺ 同二價鐵 Fe²⁺)點樣被吸收、轉化、運輸同儲存,呢啲都深深影響生物可利用率

    全面解構低鐵原因、病理機制及影響

    低鐵唔止係營養問題,仲可能係身體慢性警號

    鐵質(iron)係人體不可或缺嘅微量元素,主要負責攜帶氧氣嘅血紅素(hemoglobin)製造、能量代謝、免疫調節等。當鐵質長期攝取不足、吸收差、或失去過多,就會導致「低鐵」(iron deficiency)甚至發展成「缺鐵性貧血」(iron deficiency anemia)。本文將從臨床醫學與分子生理角度,深入探討低鐵嘅成因、病理機制、生物轉化過程,以及其對人體造成嘅連鎖影響。

    唔凍都會打冷震?

    打冷震(shivering)唔一定因為天氣凍,喺情緒波動、發燒初期、焦慮、緊張等情況下都可以出現。打冷震係一種由大腦下視丘控制嘅「非意識性肌肉收縮」,目的係維持或調節核心體溫或應對突發壓力。了解打冷震背後嘅神經與體溫調節原理,可以幫我哋區分「正常生理反應」同「潛在疾病警號」。 打冷震係乜回事...

    一緊張就流手汗?

    手掌汗腺主要受交感神經系統控制。當人面對壓力、驚訝、社交場合等刺激時,大腦會啟動「戰鬥或逃跑反應」,促使手掌、腳底等部位產生明顯出汗。這種情況屬於精神性出汗,與溫度無直接關係,係身體對外在壓力的自然反應。
