研究顯示每日步數達7000步可降低癌症風險約11%,9000步降幅達16%

Quick Look

營養師老辜引用英國《British Journal of Sports Medicine》大型前瞻性研究指出,相較於幾乎不動的人,每日活動量最高者13種特定癌症風險降低約26%;相較於每日走5000步者,走7000步降低約11%,走9000步降低約16%,且步行速度與癌症風險無明顯關係,顯示總活動量可能比速度更重要。

Why It Matters

文章引用一項發表於《British Journal of Sports Medicine》的大型前瞻性研究,追蹤英國超過8萬人,透過手腕加速度計客觀記錄每日活動量,並追蹤平均5.8年的癌症發生情形。

〔健康頻道/綜合報導〕每天一定得走到1萬步、甚至走到氣喘吁吁,才能帶來健康效益?營養師老辜分享一項大型研究指出,相較於幾乎不太動的人,每天動得最多的人,13種特定癌症發生風險降低約26%。至於相較於每天走5000步者,能走到7000步的人,癌症發生風險降低大約11%;走到9000步則下降約16%,且走路速度快慢未見明顯差異,顯示每天累積多少活動量,可能比走得多快更重要。

老辜於臉書粉專發文表示,1項發表於《British Journal of Sports Medicine》的大型前瞻性研究,追蹤英國超過8萬人,透過手腕加速度計客觀記錄每天活動量,再追蹤平均5.8年的癌症發生情形。

請繼續往下閱讀...

研究指出,相較於幾乎不太動的人相比,每天動得最多的人,他們的13種特定癌症發生風險低了約26%。此外,研究也發現,低強度身體活動(LIPA)與中高強度活動(MVPA),都與較低的癌症發生風險相關。也就是說,日常生活多散步、主動做家務、開心購物等,這些低強度活動,其實都是每天累積身體活動量的重要來源。

老辜進一步提及,研究並指出,若從步數來看,相較於每天走5000步,走得更多對於癌症風險下降狀況也更好。每天走7000步者,風險下降11%,9000步則低約16%,不過,約9000步後,風險下降幅度開始趨緩。研究也發現,在每天步數差不多的情況下,走路速度快慢與癌症風險沒有明顯關係。因此,對於降低癌症風險這件事,每天累積多少活動量,可能比走得多快更重要。

老辜強調,規律進行有氧及阻力運動當然有益健康,但增加每日總活動量,對於降低癌症風險也非常重要。建議平時不妨多走一段路、飯後散步、善用爬樓梯、主動做家事,甚至吃飽去逛街,把零碎活動累積起來,均有助於增加每天的總活動量。

A cluster of imported dengue fever families occurred in Changhua County, and a couple was diagnosed after traveling in Vietnam

A couple in their 50s from Changhua County traveled to Phu Quoc Island in Vietnam in mid-September. After returning home, they developed symptoms such as fever and muscle pain. After rapid screening, they were diagnosed with imported dengue fever. The CDC stated that the 21 people in the group were distributed in Taichung, Tainan, Hsinchu, Nantou and other counties and cities. Health tracking has been conducted to rule out local infection. It called on Chinese people to go to dengue fever-endemic areas to prevent mosquito bites, seek medical treatment if they feel unwell within two weeks after returning home, and inform their travel history.

Changhua County promotes rapid pesticide inspection on fruits and vegetables. About 140 out of 1,286 items failed. County councilors call for strengthening publicity

The Changhua County Government and Tunghai University have cooperated to launch 15 free pesticide rapid inspection services for high-risk crops. Results will be available on the same day as soon as farmers submit them for inspection. About 140 of the 1,286 rapid inspections were unqualified, with a failure rate of 11%. County councilor Wu Weida pointed out that the county government should explain whether all unqualified agricultural products are intercepted before they are put on the market. Agriculture Director Guo Zhishan explained that unqualified products will be required to be delayed in harvesting and re-inspected before they can be sold, and will strengthen drug safety propaganda and set up collection points.

Nutritionist’s analysis: It is usually fine for healthy adults to eat 1 to 3 eggs a day. For those with high cholesterol, 1 egg is recommended.

Nutritionist Sun Yukuo pointed out that generally healthy adults consuming 1 to 3 eggs per day will not significantly affect blood cholesterol, but for those with high cholesterol or abnormal blood lipids, only one egg per day is recommended, and emphasized the importance of cooking methods and overall dietary structure.
