Rasulullah menganjurkan kunyah 40 kali bagi setiap suapan. Kajian beberapa tahun lalu membuktikan kebenaran sunnah Rasulullah ini dari sudut kesihatan. Angka 40 kali ini dibuktikan oleh saintis China 2 tahun lalu sebagai jumlah yang ideal bagi memastikan kalori yang ditelan lebih rendah 12%.
Rasulullah akan mengunyah sebanyak 40 kali untuk membiarkan makanan itu betul-betul lumat agar perut kita senang memproseskan makanan itu.Sebenarnya ini menggambarkan betapa perlunya makanan itu dikunyah selumat mungkin. Kita 3 hingga 6 kali mungkin telah menelannya. Sebenarnya apabila kita mengunyah sehingga lumat, barulah nikmat makanan tersebut dirasai. Walaupun tak sampai 40 kali, tapi kunyahlah banyak kali baru telan. Ini menambahkan nikmat merasai makanan tersebut dan rasa mudah kenyang.
Ramai yang terlepas pandang bab kunyah sehingga lumat ini. Sedar tak sedar ini adalah sunnah nabi saw yang sangat penting. Maklumlah makannya terkejar-kejar sebab terlampau banyak urusan dunia yang dikejar non-stop. Sebab itu Nabi Muhammad saw sepanjang hidupnya tidak pernah sakit perut. Ini kerana kaedah pengambilan makanan dan metod serta tatacara makannya juga adalah dinamik melangkaui jangkauan ilmu sains. - rawatanislam2u
Dan dari itu, saintis dari China membentangkan di American Journal of Clinical Nutrition. Saintis itu menyebutkan bahawa orang gemuk mengunyah dengan bilangan yang paling sedikit manakala orang yang badannya normal mengunyah lebih lama berdasarkan kajiannya. Dari kajiannya juga dia mendapati mengunyah 40 kali membuatkan perut menjadi lekas kenyang dan membantu mengurangkan berat badan juga.
40 chews per bite may be key to weight loss
If you’re trying to lose weight (and aren’t we all?), here’s a study to chew on:
The more your choppers mash up each bite of food, the less food you’re likely to eat at a meal, Chinese researchers reported recently in the American Journal of Clinical Nutrition.
In other words, Mom was right again, although her advice on this subject might have stemmed more from an exaggerated fear of choking than of having to buy clothes for you in the chubby department. The new study confirms: Don’t wolf down your food. Chew it, then chew it some more.
The latest research involved 16 lean and 14 obese young men. After a 12-hour fast, the volunteers came to the laboratory to eat a typical Chinese breakfast while a video camera recorded how frequently they chewed each bite. All of the men were given the same portion and told they could ask for more.
The scientists theorized that the obese men would chew less per bite and, indeed, they were right. And while the size of their bites was similar to that of the lean men, the obese men ended up consuming more calories.
So the researchers, who were from Harbin Medical University, tried another experiment. They brought the men back to the lab and served up again for breakfast, as much as the men cared to eat. But one day they asked the men to chew each bite 15 times, while another day they asked them to chew 40 times.
Didn’t matter whether the men were obese or lean: They consumed about 12 percent fewer calories when they chewed each bite 40 times than when they chewed 15 times, and they had lower levels of ghrelin, the so-called hunger hormone produced in the stomach.
“Chewing less is a risk factor for obesity,” the scientists conclude, perhaps because increased chewing releases nutrients from food more efficiently. Encouraging people to chew more, they write, could be a valuable tool--along with diet and exercise--for helping people lose weight.
I wondered if that might be biting off more than many people could chew, so I asked Mauro Farella of New Zealand’s University of Otago how hard it would be to get folks to masticate more.
Farella was the senior author on a chewing paper posted Aug. 1 by the Journal of Dental Research. He and his coauthors had theorized that people chew at their own consistent pace, part of their unique “fingerprint of masticatory behavior.” His study didn’t find a link between the pace at which people chewed and how thoroughly they chewed.
“I have no idea about whether it would be possible to teach an individual to slow down or up the chewing pace or to change the duration of chewing before swallowing,” Farella says. In principle, though, he says it might be possible to get people to chew each bite more, because, as Mom knows, we at least have partial control over it.
