Perlukah Minum Vitamin C ?

Kita dapat menjumpai banyak vitamin c dalam kehidupan sehari-hari baik di swalayan-swalayan atau di toko-toko, disana vitamin c dijual dengan harga yang cukup murah. Banyak sediaan yang ditawarkan, mulai dari kadarnya ada yang 500 mg ada juga yang 1000 mg, ada yang rasa jeruk, atau rasa anggur, melon, strawbery,dll. Bentuknya ada bermacam-macam pula ada yang berupa tablet murni, ada yang berupa tablet effervescent ( harus diendam air dulu, setelah itu airnya bisa diminum ) sampai yang berupa sirup dengan berbagai macam rasa yang siap diteguk. Apakah perlu kita mengkonsumsinya ?

Sebenarnya yang dimaksud vit c adalah asam ascorbat, vitamin ini mempunyai sifat yang larut dalam air, karena sifatnya yang larut air ini maka tubuh kita tidak bisa lama-lama menyimpannya, karena itu kita membutuhkan suplai vitamin c yang cukup setiap hari. Sebenarnya apabila kita makan sehari-hari mengikuti pola makan yang seimbang, pasti kita tidak akan kekurangan vitamin c, karena banyak bahan makanan yang kaya akan kandungan vitamin c contohnya jeruk, pepaya, lada merah dan lada kuning, anggur, mangga, brokoli dan masih banyak lagi yang lain. Sedangkan kebutuhan vit c sehari hanya sekitar kurang lebih 45 mg sehari.

Trus apakah boleh kita minum vit c tambahan ?

Boleh-boleh aja kok, mengingat fungsi vitamin c yang sangat banyak antara lain sebagai antioksidan, berperan dalam pembentukan kolagen ( kolagen ini adalah protein yang turut membantu dalam pembentukan tulang, tulang rawan, otot dan pembuluh darah ). Selain itu fungsi vitamin c yang lain adalah membantu penyerapan zat besi, juga memelihara pembuluh darah kapiler, tulang serta gigi kita.

Seberapa banyak kita minum vitamin c ini, khan yang dijual ada yang sampai 1000 mg, apakah boleh yang ini ?, boleh aja tetapi harus diingat batas tertinggi yang masih bisa ditoleransi oleh tubuh adalah 2000 mg perhari.

Pilates Benefits

By Kimberly Dawn Neumann

The limb-elongating aspect of Pilates is only one reason why dancers and models often favor this workout. The goal with Pilates is to always feel length throughout the entire body, even while performing moves that work specific body parts. There is also an ever-present mind-body element which makes it appealing to people looking to develop that connection. The exercises can be performed both on a regular exercise mat (known as Pilates mat workouts) and on spring-based machines developed by Mr. Pilates referred to by names such as "The Reformer," "The Cadillac," and "The Chair."

The benefits of Pilates are innumerable. According to Rael Isacowitz, author of 'Pilates' (Human Kinetics, April, 2006) and a master of the Pilates method, a Pilates regimen develops strength, flexibility, coordination, speed, agility, endurance, balance, and correct posture. Plus, most of the moves are non-impact, making it a great fitness activity for , aging individuals or athletes recovering from injuries.

With Pilates mat classes, students will work to increase the strength and mobility of the spine, according to Kimberly and Katherine Corps, founders of New York City's Pilates on Fifth and the Cardiolates � workout. "Plus Pilates encourages you to keep your belly button pulled to the front wall of your spine at all times -- instead of pushing it out -- so your stomach gets super flat," says Kimberly.

Pilates equipment work uses spring resistance to challenge muscles in both phases of the contraction -- concentric and eccentric. "Thus the entire muscle is targeted so the result is the appearance of lengthened muscle instead of bulk concentrated at the belly of it," says Katherine.

To the novice, the Pilates exercise equipment can look daunting, but rest assured that each piece was developed as a tool to help students learn proper body mechanics. Because it can be intimidating, learning proper technique, which can best be done privately with an instructor, is essential. For the floor exercises, all that's needed is a cushioned mat. Technique is still important, but can be learned in a class or by watching a good DVD.
