香蕉有趣的事實

Bananas are always curved due to negative geotropism

Once a banana develops, it no longer grows toward the ground, but toward the sun. The fruit continues to grow under the influence of gravity, giving the banana its familiar curved shape.

Bananas are the best fruit source of vitamin B6

Vitamin B6 helps in the formation of red blood cells and certain brain chemicals. It affects brain processes and development, immune function, and steroid hormone activity.

Although bananas are hard, they are 75% water

This is even more than the 60% of the human body which is water.

Bananas are over 10,000 years old and are the oldest fruit in the world

This is about five times older than the Colosseum in Italy or the Parthenon in Greece. It has a history of about 2000 years ago!

Banana is both a fruit and not a fruit

Although the banana plant is colloquially known as the banana tree, it is actually an herbaceous plant that is distantly related to ginger, as the plant has a succulent trunk rather than a woody one. That yellow thing you peel and eat is actually a fruit because it contains the seeds of the plant. Although since bananas were grown commercially, the plants are sterile and the seeds have gradually shrunk to small sizes.

Much more variety than you think

Bananas are grown in more than 150 countries, and it is generally accepted that there are more than 1,000 species of bananas in the world, divided into 50 groups. The most common is Cavendish, the one most commonly produced for the export market.

banana peel

The health of the banana is often associated with its nutritional value, but less attention is paid to its peel, which contains a cocktail of acids, oils and enzymes that have some powerful off-label uses.

You can rub a banana peel against your skin to remove ink stains or soothe insect bites. You can also use the peel to polish your shoes, dust your plants, and even whiten your teeth.

Banana peels are also used in water purification, ethanol production and fertilizer – and they are often part of feed for cattle, goats, pigs and poultry.

So go ahead and use banana peels for everything. Just make sure you don't slip.

小朋友叫唔應?可能唔係無禮貌,而係科學:專注時真係聽唔到你

小朋友一睇YouTube、打機、畫畫,突然叫佢,佢完全聽唔到。係咪扮聾?係咪發展遲緩?抑或專注力問題? 研究顯示,大部分情況完全正常,與腦部的「選擇性注意力(Selective Attention)」同「過度專注(Hyperfocus)」有關,不代表有疾病。 什麼是「選擇性注意力」?(Sele...

為何肺癌早期大多沒有症狀?科學原理、風險因素與早期發現方法全解析

肺癌一直是全球最常見、死亡率最高的癌症之一。令人憂心的是,大部分肺癌患者在早期(第一、二期)都沒有明顯症狀,往往直到腫瘤擴散、壓迫周邊結構或影響呼吸功能後才被發現。本文以科學角度深入講解:為何肺癌早期「靜悄悄」、身體不察覺?身體內部究竟發生了甚麼? 亦會加入實際的自我檢查策略與醫學建議。 一...
