Recently researcher say sun cuts  prostate cancer risk. It involve with our body manufacture of vitamin D after sun exposure. Meanwhile, they say more exposure will developing skin cancer. It seems a dilemma. Thus, they suggest us increasing vitamin D from food and supplements might be the safest solution to achieve the right levels.

綠茶中的「兒茶素」具有抗氧化作用，動物實驗研究進一步發現，它可減少油煙導致的肺部傷害。研究人員認為，家庭主婦或廚師經常得暴露在油煙下煮食三餐，適度喝綠茶，可以「顧肺」，另外也最好戴口罩，減少油煙暴露的時間

台大醫院醫學研究部副教授鄭劍廷長期研究綠茶中萃取出的兒茶素效果，最近的動物實驗發現，兒茶素的抗氧化作用，對於預防油煙造成的肺部傷害也有幫助。另外，水溶性纖維，如植物種子提煉出的豆膠，或果膠、植物膠等，也有抗氧化作用。從動物實驗中推論，飲食中添加兒茶素與水溶性纖維，能提高抗氧化的表現。

鄭劍廷指出，女性罹患肺癌主因，一般認為是油煙，其次是二手菸。油煙的化學物質侵入肺部，產生自由基、活性氧族群，會造成肺部細胞傷害。在實驗中，他讓大鼠暴露在油煙環境下，發現30分鐘就會增加大鼠體內活性氧族群的數量，顯示油煙對肺部殺傷力實在不小。

研究人員在大鼠飲水添加兒茶素，再讓大鼠暴露油煙中，與沒有飲用兒茶素的另一組大鼠比較，發現飲用組的大鼠，持續飲用兩週以上，血液中和肺洗出液的活性氧族群數量都較少。

台大醫院營養部副主任鄭金寶說，動物實驗的結果是否適用於人體還有一段距離，不過在養生防癌的概念中，綠茶的確有益健康，但胃不好的人不要空腹飲用。

另外，鄭劍廷說，水溶性纖維的抗氧化能力，可減少動脈硬化。實驗先以餵食高脂食物的方式，誘使大鼠血漿中總膽固醇與低密度脂蛋白膽固醇的數值增加，產生動脈硬化，再測試水溶性纖維效果。研究人員灌食大鼠水溶性纖維，發現可降低血漿總膽固醇和低密度脂蛋白膽固醇，也可延長血栓形成的時間。

鄭金寶表示，纖維分成水溶性和非水溶性，非水溶性例如芹菜，可促進排便，水溶性例如水果中的果膠、木耳、洋菜等，有降血脂、膽固醇效果。

Cold swims may make you hungry (越冷越餓呀！)

Taking a chilly dip increases appetite, study finds
Updated: 6:25 p.m. ET May 4, 2005 from REUTERS

WASHINGTON - Taking a swim in cold water may be invigorating, but it could increase appetite enough to cause weight gain, U.S. researchers said Wednesday.

The study may help explain why it is more difficult for some people to lose weight by swimming as opposed to other forms of exercise.

The University of Florida team tested how many calories were burned by 11 volunteers while exercising in warm water and in cold water. They ate 44 percent more calories after exercise in cold water than in warm water, the researchers found.

“It’s possible that individuals who exercise in cooler water may have an exaggerated energy intake following exercise, which may be a reason why they don’t lose as much weight,” said Lesley White of the College of Health and Human Performance, who led the study.

“So it may not be the exercise itself that causes the problem because you can match the exercise energy expenditure; rather it’s the increased eating after the exercise is over.”

That is not to say exercising in water is a bad thing.

“Water exercise is an excellent activity for many people, particularly those with joint disorders, thermal regulatory problems and balance or coordination difficulties,” she said in a statement.

“However, an earlier study reported that women who swam did not lose as much weight as those who jogged or cycled.”

Writing in the International Journal of Sport Nutrition and Exercise Metabolism, White and colleagues said they had their student volunteers exercise on a stationary bicycle submerged in water for 45 minutes, in either cold water at 68 degrees F  or warm water at 91.4 degrees F

They used, on average, 517 calories cycling in the cold water and 505 in the warm water, compared to 123 calories while resting.

The students were then put into a room with food.

“We found that during the recovery period, when the subjects had access to an assortment of foods, that significantly more calories were eaten after exercise in cold water compared to exercise in warm water or at rest,” White said. Body temperature might also affect appetite, she added.

Who's the Weaker Sex?  (男人別再找藉口了)

By Karen Springen
Newsweek

May 9 issue - Men may earn more than women, run faster and buy more widescreen TVs. But when it comes to health, they trail the opposite sex in nearly every category. Stroke, cancer, diabetes, heart disease and the six other leading causes of death kill men at a higher rate than they do women. Yet men are half as likely to see a doctor regularly. "They're busy with work, and they always make excuses," says Rep. Randy (Duke) Cunningham of California, a prostate-cancer survivor who is pushing to open an Office of Men's Health at the Department of Health and Human Services. Whatever Congress decides, here are some steps men can take to live longer, healthier lives.

18 to 35. Focus on prevention. See your doctor every two years for routine tests, including blood pressure, cholesterol and sugar screens. Ryan Cooper, 28, saw his dad die of a heart attack at 40 and now visits the physician regularly. After a recent checkup showed his triglycerides (a kind of fat) were twice the normal level, he hit the gym, cut back on burgers and pizza and now has a clean bill of health. Also, perform regular self-exams for testicular cancer, the most common form of cancer among men ages 20 to 35. (See urologyhealth.org.)

35 to 50. Pay particular attention to diabetes, hypertension and heart disease. If you have a family history of colon cancer, get a colonoscopy, says Dr. Gary Martin, vice chair of the department of medicine at Northwestern University. And if you have a family history of prostate cancer, you may want to begin prostate screening. (Otherwise, start both at 50.) At 45, talk to your doctor about whether you should take an aspirin a day to help prevent a heart attack or stroke.

50s and 60s. If you have a history of high blood pressure or diabetes, ask about an ultrasound of the carotid arteries in your neck to check for blockages that could lead to a stroke. If you haven't already done so, get a colonoscopy. Have a dermatologist screen you for skin cancer and get your hearing checked every three years (see asha.org).

70s, 80s and above. If you were a smoker, ask your doctor about a sonogram to check for weak spots or bulges in your aorta, the body's largest blood vessel. And get a bone-density scan to test for osteoporosis, which affects men 10 to 15 years later than women. The bottom line: it pays to care for your health at every age.

Recently a team at University College London announced with fMRI (functional magnetic resonance imaging) they could tell what a person was thinking deep down.

It could potentially be used to find out people's latent attitudes and beliefs that they are not aware of.

"You could use it to detect people's prejudices, intuition and things that are hidden and influence our behaviour."

調查發現：香港男士陰莖不遜西方人
一般人認為西方男士的陰莖較亞洲人長和大，但香港一家醫院進行的一項調查卻發現，香港男士陰莖軟狀態長度平均為八點四六厘米，不遜於身材普遍較高大的西方人。

香港仁安醫院在去年十月至今年二月，為一百四十八名平均年齡為六十一歲的男士進行體格檢查及量度陰莖長短大小。

調查結果發現，他們的陰莖軟狀態長度平均為八點四六厘米，即使跟參與者平均年齡較低的美國（八點八厘米）、德國（八點六厘米）及以色列（八點三厘米）比較，分別不大。

軟狀態陰莖中段圓周平均為八點二六厘米，稍勝於參與者較年輕的菲律賓（八點二二厘米）及以色列（八點一厘米）；陰莖伸展長度平均為十點五五厘米，位列中間。調查也發現，年齡愈大、陰莖愈長；體重愈高，陰莖愈短，但未有醫學解釋。

仁安醫院泌尿中心總監陳龍威二十日在記者會上表示，結果反映港男陰莖大小及長短絕不遜於西方人。他以此調查為基礎，為港男「正常」陰莖大小長短下定義：軟狀態陰莖長度平均約八點五厘米，軟狀態時陰莖中段圓周平均為八點三厘米。如果陰莖長度短於五厘米，則屬短小；陰莖圓周大於六厘米，則屬正常。

陳龍威強調，即使陰莖長短大小「不達標準」，如沒有影響性生活，則不用求醫或接受治療，因陰莖大小、長短與性能力完全無關。

You and I will not deny that happy is better for our body. Recently at University College London teams published about happier people face stress had low levels of a chemical with increases the risk of heart diesase. Meanwhile, this month Time(時代解讀)  magazine topic is "mind & body happiness". Althought I have no time to read it, I think we should to know what is happiness and how to looking for. Well, whatever we meet some trouble look positive and optimistic mind is significant and help us to get through this. Less angry more happy.

This research from Hong Kong. They found dim sum(點心) contains high in fat and sodium and excessive consumption will increase the risk of obesity. Here is some essay that "Researchers analyzed 75 popular dim sum snacks for carbohydrates, protein, total fat, saturated fat, cholesterol, dietary fiber, sugar, sodium and calcium. Results showed that total fat, saturated fat and sodium were generally high while calcium and dietary fiber were low." To conclude it, if eat too much this will increase the risk of obesity. They suggest that we should order more steamed buns and fewer pan-fried and deep-fried items. Next time, go to tea-houses beware this.

When talking about obesity it seems a criminal. I had heard England authorities will make a low to againest it. Recentlly I feel body too fat need more exercise. I had set a long-term schedule like swimming, running and walking. We all know Rome wasn't built in a day. Juest be patience.

這是一篇很有趣的Business報告，刊登在MSNBC裏，研究指出，長得帥、好看、苗條的人，因為自信及其它而比別人得到更多的Pay，雖然不是一定論，但多少也有參考價，文中就舉例提到 “That is one of the reasons movie stars are attractive. That’s who people want to go see. Those stars are more bankable.”

也許真的是如此喔！不過好看帥的人，當然也同時要提升自己的內函特質，我相信內在也會影響外表的。
