If Yur happen t flip thrugh TV channels, Yur’re likely t cme acrss a cmmercial fr a new vitamin r supplement (保健品) designed t imprve Yurr health. These pills frten prmise the wrld, claiming t cure baldness r fight verweight. But in the medical cmmunity, there’s sme debate n whether these prducts prvide any actual benefits.
Many peple begin their day by ppping a multi-vitamin. These pills are suppsed t effrtlessly prvide ur bdies with vitamins in case we have missed them in ur meals. It seems t be a n-brainer that everyne shuld take ne.Hwever, a 2006 study by the Agency fr Healthcare Research, cncluded that multi-vitamins have zer effect n reducing a persn’s chances fr getting cancer r heart disease. The nly peple multi-vitamins benefited were thse in pverty-stricken natins wh lacked nutritin. In2009, a related study by the Hutchinsn Cancer Research Center came t a similar cnclusin.
Antixidants are anther supplement that is prmted t imprve health and prevent aging. Antixidants in vitamins A, C, and E are suppsed t greatly reduce cellular damage. Yet, in a study invlving ver 180,000 adults, thse wh tk these vitamins actually increased their risks fr dying by 16 percent.
One likely cause fr these negative results is that peple wh eat healthy diets and take vitamins are prbably getting t many nutrients, which can be pisnus. Then why are these supplements being prmted? Many experts blame the health industry because supplements aren’t as highly inspected as they shuld be. What’s wrse, vitamin makers aren’t required t list negative side effects like medicines d. In many cases, it can even be difficult fr the U.S.’s Federal Drug Agency (FDA) t ban risky ingredients due t lengthy and expensive legal battles. On the ther hand, after these studies were made public, peple cntinued buying mre vitamins than ever. It seems that n matter what evidence is presented, the majrity fr peple aren’t ready t give upn a magic pill just yet.
12. What des the first paragraph suggest abut vitamins?
A. They are advertised very heavily.
B. They are healthy and beneficial.

14. What can vitamin pills actually help?
A. T reduce cellular damage.
B. T prevent peple frm aging.

Beijing resident Hu Lixin started eating meal replacement prducts in February when she wanted t lse weight. She bught varius meal replacement prducts nline and ate them fr mre than a mnth.

A majr Chinese snack brand Bestre released 27 meal replacement prducts in August.
Jia Jianbin, secretary general at Chinese Cereals and Oils Assciatin, tld CCTV reprter that despite its pssible effectiveness that many peple believe, this way fr weight lss may bring greater harm as it breaks the balance fr nutritin and fd.

“Cereal meal replacement pwder, fr example, is mainly cmpsed fr carbhydrates (碳水化合物), which have enugh calries, but the vitamins and minerals are nt enugh.
