Gula Darah Itu Apa? Begini Penjelasannya?

gula darahGula darah adalah mengacu pada gula yang mengalir melalui aliran darah tubuh kita guna memasok energi untuk semua sel dalam tubuh kita.

Gula ini terbuat dari makanan yang kita makan. Tubuh manusia mengatur kadar glukosa darah sehingga membuat tidak terlalu tinggi atau terlalu rendah untuk menjaga kondisi stabilitas atau keseimbangan di dalam darah tubuh kita (homeostasis) dan sangat diperlukan dan berfungsi bagi tubuh kita.

Keliru pada penggunaan kata “gula” di “gula darah” adalah istilah sehari-hari. Glukosa merupakan salah satu jenis gula. Gula sangat sederhana bentuknya seperti butiran kristal.

Tubuh kita mencerna karbohidrat menjadi glukosa, gula dala darah yang dapat dengan mudah mengkonversi menjadi energi. Rumus kimia untuk glukosa adalah C 6H 12 O 6 .

Sistem pencernaan manusia memecah karbohidrat dari makanan menjadi berbagai molekul gula salah satunya adalah glukosa, sumber utama energi tubuh. Glukosa akan langsung dari sistem pencernaan ke dalam aliran darah setelah makanan dikonsumsi dan dicerna.

Glukosa hanya dapat memasuki sel jika ada insulin dalam aliran darah. Tanpa insulin sel-sel akan “kelaparan”. Setelah makan, konsentrasi gula darah meningkat, pankreas melepaskan insulin secara otomatis sehingga glukosa memasuki sel, karena semakin banyak sel menerima glukosa, kadar gula darah turun menjadi normal lagi.

Glukosa berlebih disimpan sebagai glikogen dalam hati dan otot. Setelah makan kadar glukosa meningkat, insulin dilepaskan dari pankreas ke dalam aliran darah, kadar gula darah turun kembali, Jika Anda belum makan untuk sementara dan darah glukosa konsentrasi tetap turun, pankreas melepaskan hormon lain yang disebut glukagon. Glukagon memicu pemecahan glikogen menjadi glukosa, sehingga mendorong kadar glukosa darah kembali ke normal.

Kita harus sadar terhadap kesehatan gula darah sejak dini. Inilah awal dari sumber penyakit hebat seperti diabetes. Diabetes penyakit berbahaya di dunia dan bukan penyakit instan, namun penyakit yang tertanam di dalam tubuh kita akibat pola hidup sehat yang salah.

Makanan menjadi faktor penting meningkatnya gula darah, sebisa mungkin harus mengatur pola makan yang sehat pula.

  1. Large-scare program of plastic extruders can reduce creation fees.
    In the cross over or perhaps soften step, the main width within the attach heightens even though the peak on the flight journey
    will reduce. This heated plastic is also kept moving rapidly to prevent any
    premature hardening or deformities on the finished product.

  2. The other day, while I was at work, my cousin stole my apple ipad and
    tested to see if it can survive a 30 foot drop, just so she can be a youtube sensation. My
    iPad is now destroyed and she has 83 views. I know
    this is entirely off topic but I had to share it with someone!

  3. This is the perfect website for everyone who wishes to

  9. Currently the soften goes to the metering component, where the screw height
    remains consistent. This mess which is used so that you can propel the
    liquid plastic resin right out the kick the bucket may be the crucial part of your bang extruder.
    This heated plastic is also kept moving rapidly to prevent any premature hardening or deformities on the finished product.

  10. To understand the process that plastic extrusion companies use to manufacture
    their own products, you have to have some knowledge of chemistry and
    an understanding of the complex machines that are used in the manufacturing process.
    The length-to-diameter ratio, pitch, length of each zone and helix
    angles of a screw must all be matched to the plastic type being used.

    The barrier screw in designed to counter this problem.

  11. Compared to other heaters they are very economical, dependable and efficient.
    This mess which is used so that you can propel the liquid plastic resin right out
    the kick the bucket may be the crucial part of your bang extruder.
    The ceramic heaters that have got no fans in them can be used for small areas only.
