Multivitamins Urged for All Pregnant Women
A recent study in Tanzania found that whenpregnant women took vitamins every day, fewer babies were born too small.Babies that weigh less than two and one-half kilograms at birth have a greaterrisk of dying. Those that survive are more likely to experience problems with theirdevelopment. And experts say that as adults they have a higher risk of diseasesincluding heart disease and diabetes. The World Health Organization estimatesthat every year twenty million babies are born with low birth weight. Nine outof ten of them are born in developing countries.
The new study took place in Dar es Salaam.4,200 pregnant women received multivitamins. The pills contained all of thevitamins in the B group along with vitamins C and E. They also containedseveral times more iron and folate than the levels advised for women indeveloped nations. Pregnant women especially in poor countries may find itdifficult to get enough vitamins and minerals from the foods in their diet.
The scientists com#pared the findings withresults from a group of 4,000 women who did not receive the vitamins. A reportby the scientists, from the United States and Tanzania, appeared in the New England Journal of Medicine. WafaieFawzi of the Harvard University School of Public Health led the study. None ofthe women in the study had HIV, the virus that causes AIDS. The scientistsreported earlier that daily multivitamins were a low-cost way to reduce fetaldeaths in pregnant women infected with HIV. The earlier work in Tanzania alsofound improvement in the mothers in their number of blood cells known aslymphocytes. Lymphocytes increase the body’s immunity against infection.
The new study in pregnant women who werenot infected with the AIDS virus found that multivitamins reduced the risk oflow birth weight. Just under eight percent of the babies born to women who tookthe multivitamins weighed less than 2,500 grams. The rate was almost nine andone-half percent in the group of women who received a placebo, an inactivepill, instead of the vitamins. But the vitamins did not do much to reduce therates of babies being born too early or dying while still a fetus. Still, theresearchers say multivitamins should be considered for all pregnant women indeveloping countries.
US Signs GlobalTobacco Treaty
1 The UnitedStates has taken the first step toward approving a global tobacco treaty thatpromises to help control the deadly effects of tobacco use throughout theworld. Health and Human Services Secretary Tommy Thompson signed the FrameworkConvention on Tobacco Control (FCTC) this week at the United Nations. (46)_____

(48)_____It also requires banson tobacco advertising, though there are some exceptions for countries like theUnited States, where the Constitution prohibits such an outright ban.
4 (49)_____ TheWorld Health Organization estimates that tobacco use kills nearly 5 millionpeople worldwide every year. In the US alone, about 440,000 people die eachyear from tobacco-related illnesses; about one-third of all cancers in the USare caused by tobacco use.

“Clean your plate!” and “Be a member of theclean-plate club!” Just about every kid in the US has heard this from a parentor grandparent. Often, it’s accom#panied by an appeal: ”Just think about thosestarving orphans in Africa!“ Sure, we should be grateful for every bite offood. Unfortunately, many people in the US take too many bites. Instead ofstaying “clean the plate”, perhaps we should save some food for tomorrow.
According to news reports, US restaurantsare partly to blame for the growing bellies. A waiter puts a plate of food infront of each customer, with two to four times the amount recom#mended by thegovernment, according to a USA Today story. Americans traditionally associate quantity with value and mostrestaurants try to give them that. They prefer to have customers com#plain abouttoo much food rather than too little.
Barbara Rolls, a nutrition professor atPennsylvania State University, told USA Today that restaurant portion sizesbegan to grow in the 1970s, the same time that the American waistline began toexpand.
Health experts have tried to get manyrestaurants to serve smaller portions. Now, apparently, some customers arecalling for this too. The restaurant industry trade magazine QSR reported lastmonth that 57 percent of more than 4,000 people surveyed believe restaurantsserve portions that are too large; 23 percent had no opinion; 20 percentdisagreed. But a closer look at the survey indicates that many Americans whocan’t afford fine dining still prefer large portions. Seventy percent of thoseearning at least $150,000 per year prefer smaller portions; but only 45 percentof those earning less than $25,000 want smaller.
It’s not that working class Americans don’twant to eat healthy. It’s just that, after long hours at low-paying jobs,getting less on their plate hardly seems like a good deal. They live frompaycheck to paycheck, happy to save a little money for next year’s Christmas presents.
