>Supplements show no meaningful health benefits




Vitamin, mineral and multivitamin supplements aren’t likely to protect you from cancer, heart disease or overall mortality, according to updated guidelines released in the journal JAMA. 美国预防医学工作组近期发表在《美国医学会杂志》上的新指南中写道,维生素、矿物质和复合维生素补充剂无法保护你不患癌症、心脏病,也不能帮你延长寿命。

“Rather than focusing money, time, and attention on supplements, it would be better to emphasize lower-risk, higher-benefit activities … following a healthful diet, getting exercise, maintaining a healthy weight and avoiding smoking,” Dr. Jeffrey Linder, chief of general internal medicine at Northwestern University, wrote in the guidelines.


There are some populations who do need certain vitamins — some seniors may need additional supplementation of vitamins B12 and B6 as absorption of those vitamins from food fades as we age — but levels should be checked by a doctor.

但某些人群确实需要服用特定维生素,比如一些老年人可能需要补充维生素B12和维生素B6,因为随着年龄增大,他们从食物中吸收的这些维生素会减少, 但是用量必须遵医嘱。

The number of dead migrants found in a truck in Texas rose to 53 on Wednesday, according to the Bexar county medical examiner’s office. 据得州贝克萨县法医办公室29日消息,在美国得克萨斯州一辆卡车上发现的移民死亡人数上升至53人。

The suspected driver and an accused conspirator were charged in U.S. federal court with human trafficking offenses.


The migrants died inside a tractor-trailer in San Antonio, where temperatures swelled to a high of 39.4 degrees Celsius.


> Seville to name, classify heat waves to protect public

The southern Spanish city of Seville will become the first in the world to name and classify heat waves – much in the way tropical storms or hurricanes are named – in an effort to better shield residents as periods of excessively hot weather become more frequent. 西班牙南部城市塞维利亚将成为世界上首个给热浪命名和分级的城市,命名方式和热带风暴飓风类似,目的是在酷热天气愈发频繁的现状下更好地保护居民安全。

The initiative is part of a broader set of measures, from emissions reductions to decarbonization, aimed at countering climate change, said the city’s mayor, Antonio Mu?oz.


The pioneering program comes days after Spain sweltered through one of its earliest heat waves on record and a May that ranked as the hottest in 58 years.
