A high-carb diet may explain why Okinawans live so long 沖繩人長壽秘訣:與高碳水化合物飲食有關?

地瓜是主食......

So could the “Okinawan Ratio” – 10:1 carbohydrate to protein – instead be the secret to a long and healthy life? Although it would still be far too early to suggest any lifestyle changes based on these observations, the very latest evidence – from human longitudinal studies and animal trials – suggest the hypothesis is worth serious attention. According to these findings, a low protein, high carbohydrate diet sets off various physiological responses that protect us from various age-related illnesses – including cancer, cardiovascular disease and Alzheimer’s disease. And the Okinawan Ratio may achieve the optimal dietary balance to achieve those effects.

纖維的好處“It’s pretty well impossible” to get enough fibre from fruit and vegetables alone.

攝入食品的纖維質,量要高,才可防心臟病,所以只吃水果、蔬菜是不夠的。



纖維——它算不上世界上最誘人的東西,但是有一項重大研究弄清楚我們到底需要攝入多少纖維,同時還發現,它對健康有巨大的益處。
「現在證據已經很充分,這是一個轉折點,人們必須要開始採取一些行動了,」參與研究的專家之一約翰·庫明斯教授(Prof John Cummings)向BBC表示。
眾所周知的是,它能夠阻止便秘,但事實上,它對健康的好處遠不止於此。

我們需要多少纖維?

參與研究的新西蘭奧塔哥大學(University of Otago)和英國鄧迪大學(University of Dundee)學者表示,人每天應該至少吃25克的纖維。
不過,他們說這只是為了讓身體更加健康的「恰當」攝入量。如果努力將攝入量增加到30克(1盎司)的話,將會有更多的好處。

聽起來也不多?

好吧,一根香蕉本身大約重120克,但是它並非完全是纖維。減去其他所有東西,比如天然糖分和水,你就大概剩下3克左右的纖維。
全世界大部分人每天的纖維攝入量都少於20克。
在英國,10個成年人裏面只有不到一個能夠每天吃30克纖維。
平均而言,女士每天攝入約17克纖維,男士則是21克。

哪些食物含有更高纖維?

富含纖維的食物包括水果、蔬菜,其中一些使用全麥的穀類早餐、麵包和意粉,扁豆或鷹嘴豆等豆類,以及各種堅果和種子等等。

30克到底是多少?

奧克蘭科技大學(Auckland University of Technology)的營養學教授艾琳·拉什(Elaine Rush)舉出以下例子,說明如何能夠達到25-30克的纖維攝入量:
  • 半杯燕麥片=9克纖維|兩塊維多麥(Weetabix)=3克纖維|一塊厚的棕色麵包=2克纖維|一杯煮熟的扁豆=4克纖維|一個連皮煮熟的土豆=2克纖維|半杯莙薘菜=1克纖維|一根胡蘿蔔=3克纖維|一個連皮的蘋果=4克纖維
不過,她表示:「在飲食中增加纖維的攝入並不容易。」

Image caption在日常食物中,30克的纖維是什麼概念?
庫明斯教授對此表示同意。「這對人們來說是一個大改變,」他說,「這是有難度的。」

有沒有簡單快捷的竅門?

英國國民保健署(National Health Service)有一整個頁面在介紹這些方法。
當中包括:
  • 土豆要連皮煮|麵包、意粉和米都選擇全麥的類別|選擇高纖維的穀物早餐,比如燕麥粥|在咖喱或者沙拉里加點鷹嘴豆、大豆或者扁豆|用堅果或者新鮮水果做甜品|每天至少吃五份水果或者蔬菜

纖維的好處有哪些?

在分析了185項研究和58次臨牀試驗之後,研究結果發表在了醫學期刊《刺絡針》(Lancet,另譯《柳葉刀》)上。
報告顯示,如果將1000人從低纖飲食(少於15克/日)轉向高纖飲食(25-29克),這一千人當中將會少13宗死亡和6次心臟病。
那還只是計算了這些研究進行期間的數據,即在跟蹤這些對象的十至二十年內。
研究還顯示,2型糖尿病和腸癌的風險也會減少,而體重、血壓和膽固醇也會更低。
而且,纖維吃得越多,健康就會越好。












如果你有意進行「低碳飲食」,這篇文章或許能給你更多發現。

Liquid paraffin, Paraffin Wax


Injection of Paraffin (Parapin chusha) from Ehagaki sekai
Japanese Late Meiji era 1908

Paraffin oil injection in the body: an obsolete and destructive procedure.

Abstract

Injection of foreign materials, such as paraffin oil, is an old and obsolete procedure. The authors describe previous uses for this procedure that had been used since the 19th century and the treatment of patients affected by such a disease.





Paraffin Wax

Today, doctors use Botox and collagen to rejuvenate faces. Back in the 19th century, some doctors used injections of paraffin to smooth out wrinkles.

Paraffin was also injected into women's breasts, in an early attempt at breast augmentation. But the practice fell out of favor - and for good reason. It caused formation of hard, painful lumps known as paraffinomas.

    Liquid paraffin, also known as paraffinum liquidum, is a very highly refined mineral oilused in cosmetics and for medical purposes. This is a UK definition (British Pharmacopoeia) and the term may have different uses in other countries. The cosmetic or medicinal liquid paraffin should not be confused with the paraffin (or kerosene) used as a fuel.
    The term paraffinum perliquidum is sometimes used to denote light liquid paraffin. Conversely, the term paraffinum subliquidum is sometimes used to denote a thicker mineral oil.

    Usage and side effects orally as laxative[edit]

    Liquid paraffin is considered to have a limited usefulness as an occasional laxative, but is unsuitable for regular use as it can seep from the anus and cause irritation.[citation needed]
    Efficacy of liquid paraffin is suggested by 2016 Cochrane review.[1]
    It might interfere with the absorption of fat-soluble vitamins, though evidences seem low.[2]
    It can be absorbed into the intestinal wall[citation needed], and may cause foreign-body granulomatous reactions in some rat species but not in others and that reaction might not occur with human.[3]
    There are evidences suggesting the lack of carcinogenicity.[4]
    If it enters the lungs, it can cause lipoid pneumonia.[5]
    Liquid paraffin is also used in combination with magnesium as an osmotic laxative, sold under the trade name Mil-Par (among others).[6]

    Side effects if injected[edit]

    Causes granulomatous reactions if injected.[7]
