생각보다 건강에 위험한 음식들 -충격

 

 

소고기
아마도 여러분이 가장 많이 접한 유기농 고기는 "유기농 닭고기"일 것이다. 그러나, 진짜로 유기농으로 구입해야 하는 고기는 다름이 아니라 소고기다. 왜냐면 소에게 주입되는 호르몬이 인간에게 미치는 영향이 좋지 않다는 연구 결과가 있기 때문이다. 특히, 소에게 주입되는 약물 중에는 에스트로겐(여성 호르몬)과 비슷한 작용을 하는 물질이 있어서 유방암을 유발할 수도 있다고.

물론 당국에서 소고기에 주입되는 약물의 양과 종류를 통제하고 있긴 하지만, 모든 소고기 식품들이 이런 규정을 따르고 있다고 보긴 어렵다. 이미 여러 차례의 연구 결과, 소고기 식품에서 호르몬 잔유물이 발견된 바도 있다. 호르몬은 비록 소량이라고 하지만, 소들에 투여되는 항생제의 잔류물은 더욱 무시하기 어렵다.


딸기
딸기는 몸에 가장 좋은 과일 중 하나이지만, 이 과일에는 13종류나 되는 다량의 살충제가 뿌려지는 것으로 유명하다. 게다가 딸기의 표면은 작은 씨앗들로 촘촘히 박혀 있기 때문에 살충제가 잘 닦이지 않게 되고, 결국 다량의 살충제를 그대로 먹을 위험이 높다는 것이다.

딸기와 함께 사과, 복숭아, 블루베리, 체리 역시 많은 종류의 살충제가 투여되는 과일들이다.


조리 기구
냄비와 프라이팬은 사실 음식보다도 더 건강에 큰 위협이 될 수 있다. 불행히도 대부분의 눌어붙지 않는 요리 기구들에는 PTFE라 불리는 불소화학물이 함유돼 있다. 이 화학물질은 과열되면 독성 연기를 뿜는다. 이 독성 연기는 폐 안쪽에 눌어 붙어 알러지 비슷한 증상을 일으킬 수 있다.

이를 피하려면 눌어붙지 않는 조리 기구 대신, 스테인레스, 세라믹 등으로 만들어진 도구를 사용하는 것이 바람직하다.


물병/플라스틱 용기
상당수의 플라스틱 물병과 플라스틱 용기들이 아직 bisphenol A(BPA)를 포함안 성분으로 만들어지고 있다. BPA는 여성의 유방암 위험을 높일 뿐 아니라 남성의 정자 수를 감소시키는 부작용을 부를 수 있다. BPA 물병에 물을 담아 놓는 것만으로도 이 물질이 새어 나올 수 있으니 주의가 필요하다.


우유
연구에 따르면 우리가 음식으로 섭취하는 에스트로겐의 60-70%가 우유에서 섭취되는 것으로 나타났다. 즉, 우리들은 우유를 통해 원치 않는 호르몬을 다량 복용하고 있다는 사실이다. 이는 소에게 우유를 짜내기 위해 주입되는 엄청난 양의 호르몬이 우유를 통해서도 어느 정도 빠져 나온다는 것이다. 우유 목장의 소들의 17%가 우유를 생산하기 위해 rBST(rBGH) 호르몬을 주입받고 있는데, 이로 인해 암 발생률이 높아질 수 있다.

이미 유럽과 캐나다에서는 rBST의 사용을 금지시켰다. 앞으로 우유를 구입할 때는 rBGH(rBGH)가 들어있지 않은 것을 고르는 것이 좋다. rBGH-free라고 씌여진 우유는 인공 호르몬을 주입하지 않은 소로부터 생산된 우유이기 때문이다.


셀러리
전문가들이 식용 채소와 과일 중 가장 오염도가 심한 것들을 조사해 봤더니 그중 1위가 바로 셀러리였다. 문제는 셀러리 줄기에 작은 구멍이 매우 많다는 점이다. 이곳으로 살충제가 흘러들어가 씻어도 빠져 나오지 않는다는 것이다. 셀러리 외에도, 피망, 시금치, 감자 역시 농약을 많이 함유한 채소류로 꼽히고 있다.

By now, we all know there’s a benefit to buying some stuff organic. But these days you’re faced with the option of getting everything organic—from fruits and veggies to mattresses and clothing. You want to do right by your body, for sure, but going the all-natural route en masse can be pricey.

So we wondered: What’s really essential for our health? That’s why we came up with this definitive list. Here's what should be in your cart—and what you don’t have to worry about.

Beef
You’ve probably read plenty of stories about the risks of eating chicken. But the most important protein to buy organic may well be beef. "Research suggests a strong connection between some of the hormones given to cattle and cancer in humans, particularly breast cancer," says Samuel Epstein, MD, professor emeritus of environmental and occupational medicine at the University of Illinois at Chicago School of Public Health. Specifically, the concern is that the estrogen-like agents used on cattle could increase your cancer risk, adds Ted Schettler, MD, science director at the Science and Environmental Health Network.

Though there are strong regulations about the use of hormones in cattle, "not all beef producers are following those regulations strictly, and some studies continue to find hormone residue in cattle," Dr. Schettler says. When you buy beef that’s been certified organic by the United States Department of Agriculture (USDA), you’re not only cutting out those hormones, you’re also avoiding the massive doses of antibiotics cows typically receive, which the USDA says may lead to the development of antibiotic-resistant bacteria in people.

Strawberries
Strawberries may be a superfood—but they pose a potential risk unless you go organic. In addition to having up to 13 pesticides detected on the fruit, according to an Environmental Working Group (EWG) analysis, conventional "strawberries have a large surface area and all those tiny bumps, which makes the pesticides hard to wash off, so you’re ingesting more of those chemicals," explains Marion Nestle, PhD, a professor of nutrition and public health at New York University and author of What to Eat.

If you can, also skip conventional peaches, apples, blueberries, and cherries, which are typically treated with multiple pesticides and usually eaten skins-on.

Cookware
Your pots and pans are just as crucial to upgrade as the food you cook in them: "Most nonstick cookware contains a fluorochemical called PTFE that breaks down to form toxic fumes when overheated," says Olga Naidenko, PhD, a senior scientist at the EWG. "Those fumes can coat the inside of the lungs and cause allergy-like symptoms."

Tests commissioned by the EWG showed that in just two to five minutes on a conventional stove top, cookware coated with nonstick surfaces could exceed temperatures at which the coating emits toxic gases. Switch to stainless steel, ceramic, or cast iron cookware.

Popcorn
The linings of microwave-popcorn bags may contain a toxic chemical called perfluorooctanoic acid, or PFOA, which is used to prevent the food from sticking to the paper. According to the Environmental Protection Agency (EPA), PFOA is a likely carcinogen. "We don’t know all of the hazardous effects of PFOA yet, but we have some evidence of a link to cancer, as well as to effects on the immune, nervous, and endocrine systems," says David Carpenter, MD, director of the Institute for Health and the Environment at the University at Albany.

Pick up an air-popper or make your popcorn in a pan on the stove top.

Yard pesticides
Some lawn and garden pesticides contain suspected carcinogens, according to EPA data. Long-term pesticide exposure may be related to changes in the brain and nervous system, the Fred Hutchinson Cancer Research Center reports. "Not only are you breathing the chemicals in, but you bring them indoors and onto carpets via your shoes," says McKay Jenkins, PhD, a journalism professor at the University of Delaware and author of What’s Gotten Into Us?

Healthier brands like BurnOut and EcoClear are made from vinegar and lemon juice, and are effective weed-killers.


All-purpose home cleaners
Time for spring-cleaning? Using common household cleaners may expose you to potentially harmful chemicals. Ammonia and chlorine bleach can irritate the skin, eyes, and respiratory tract. And some cleaners contain phthalates, some of which are endocrine disruptors, meaning they interfere with normal hormone activity, says EWG senior scientist Becky Sutton, PhD.

Although there’s no definitive proof that phthalates cause problems in humans, "the greatest concern is how early-life exposure will affect male [reproductive] development," Dr. Carpenter says. There’s weaker evidence, he adds, that phthalates affect the nervous and immune systems. Go natural with the cleaner you use the most frequently and in the most places, such as kitchen-counter spray—look for brands approved by Green Seal or EcoLogo, two organizations that identify products that have met environmental label guidelines.


Water bottles
You’ve probably heard that many hard, reusable plastic water bottles could be bad for you because they may contain BPA, or bisphenol A, another endocrine disruptor according to the National Institute of Environmental Health Sciences.

"For adults, the biggest concern with BPA is that it may increase the risk of breast cancer in women and reduce sperm counts in men," says Dr. Carpenter, who explains that BPA can leach out into the water in the bottle. To be safe, sip from an unlined stainless steel or BPA-free plastic bottle.

Food-storage containers
BPA strikes again: Many food-storage containers are made of the hard, clear polycarbonate plastic that may contain BPA. As is the case with water bottles, the BPA can leach out of the plastic in these containers and seep into your leftovers.


"The leaching is increased during heating, but it also leaches to a smaller degree even when cold foods are stored," Dr. Carpenter explains. Glass containers are your safest—not to mention planet-friendly—bet. Both Rubbermaid (at left) and Pyrex make glass ones with BPA-free plastic lids.

Milk
The milk you’re drinking may not be doing your body good: Dairy products account for a reported 60 to 70 percent of the estrogens we consume through our food. If that seems like a shockingly large number, it’s mainly because milk naturally contains hormones passed along from cows. What worries some experts is that about 17% of dairy cows are treated with the hormone rBST (or rBGH), which stimulates milk production by increasing circulating levels of another hormone called insulin-like growth factor (IGF-1).

"Elevated levels of IGF-1 in people are associated with an increased risk of cancer, including breast cancer," Dr. Schettler explains. In fact, the use of rBGH is banned in Europe and Canada. Although research has yet to definitively conclude whether drinking rBGH-treated milk increases your IGF-1 levels high enough to cause concern, Dr. Schettler says it’s advisable to buy milk that hasn’t been treated with it. So pick up milk that’s labeled rBGH-free, rBST-free, or is produced without artificial hormones.

Celery
When researchers at the EWG analyzed 89,000 produce-pesticide tests to determine the most contaminated fruits and vegetables, celery topped the chart. "In terms of the sheer number of chemicals, it was the worst," says Sonya Lunder, senior analyst at the EWG. Celery stalks are very porous, so they retain the pesticides they’re sprayed with—up to 13 of them, according to the EWG analysis. Lunder also advises buying organic bell peppers, spinach and potatoes because they scored high for pesticides, as well.

Tomato sauce
When picking up tomato sauce or paste, choose the glass jar or box over the can. "The lining on the inside of food cans that’s used to protect against corrosion and bacteria may contain BPA," explains Cheryl Lyn Walker, PhD, a professor of carcinogenesis at MD Anderson Cancer Center and past president of the Society of Toxicology.

In 2009, Consumer Reports tested BPA levels in a variety of canned foods and found it in nearly all of the brands tested, suggesting that the chemical leaked in. "What can happen is that BPA in the lining can leach into the food," Walker explains.
