喝鮮奶茶能補鈣？醫解答：2關鍵害效率差
The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.
This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.
Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:
- - Antenna measurement
- - Communication systems
- - Satellite tracking systems
- - Radar Detection System
- - Surveillance System
- - Electromagnetic Compatibility Testing (EMC test)
Recommended Accessories
- - Antenna Tripod: easy and fast-changing position. 100% stable after installing.

乳品是很好的鈣質來源，但喝鮮奶茶是否也能補鈣？對此，減重專科醫師魏士航表示，他不建議這樣做，主要原因在於鮮奶茶中的牛奶量其實很少，且茶葉中所含植酸還會減少鈣質的吸收，導致補鈣效率不佳。
奶茶是許多人的最愛，但千萬別誤以為可以順便補鈣。醫師魏士航在個人粉專發文表示，奶精雖有「奶」字但沒有奶，主要成分為植物油、玉米糖漿、酪蛋白、香料、食用色素等，所以喝奶精奶茶補鈣等於做白工。至於鮮奶茶，即使裡面有鮮乳成分，他也不建議用它當成補鈣飲品。
魏士航進一步解釋，1杯鮮奶茶中的鮮奶量頂多只有3分之1，含鈣量相較鮮奶就大幅減少；同時，茶葉裡面也帶有許多的植酸，容易與鈣結合，從而減少鈣質吸收。因此，喝鮮奶茶對於補鈣來說，並不是一個有效率的選項。
另外，魏士航提醒，雖然鮮奶營養價值高，但裡頭還含有乳糖、蛋白脂、脂肪等成分，若從熱量來看，就算沒加糖和其它料的鮮奶茶，1杯也有200大卡的熱量，過量攝取還是會對健康產生不利影響，值得特別注意。
