Vaping May Damage the Heart as Much as Smoking, Experts Say

It’s no secret that smoking is toxic. E-cigarettes seemed to be the safe alternative, avoiding harmful chemicals and salvaging good health. But researchers are now saying that e-cigarettes have plenty of health risks of their own – including damaging effects to the heart. In a study presented at the European Society for Cardiology congress in Rome, the world’s largest cardiology conference, researchers found that vaping may have the same negative impact on heart health as smoking. E-cigarettes have been discovered to have adverse effects on the main artery of the heart. Researchers studied the hearts of 24 smokers while they puffed on ... Read More

Worker exposure to diacetyl is much more widespread than initially thought

Bronchiolitis obliterans, an irreversible lung disease, first attracted attention 16 years ago when it was diagnosed in a handful of workers at a microwave popcorn processing plant in rural Missouri. The disease, now referred to as “popcorn lung,” has been linked to diacetyl exposure. The disease happens when the smallest airways of the lung become scarred and restricted. The only treatment is lung transplant. David Egilman, a doctor and clinical professor of family medicine at Brown University in Providence, R.I., said of the disease, “It’s like you’re drowning all the time.” Diacetyl and its substitute, 2,3-pentanedione, is a flavoring agent that is used in many products ...

Study: Flavored E-Cigarettes are More Toxic Than Regular E-Cigarettes

All e-cigarettes have been found to contain many potentially harmful chemical compounds, as well as carcinogens. However, a new study indicates flavored e-cigarettes may be more harmful than non-flavored, and one flavor is reportedly the most toxic of all. Formaldehyde, acrolein, acetoin, propylene glycol, glycerin, diacetyl and 2,3 pentanedione have all been detected in e-cigarette liquids and their vapors. The risk level of exposure depends on how old the e-cigarette is, how many coils it has, temperature, voltage, flavor and brand. A study published in Tobacco Control, a division of BMJ Online Magazine, discovered that, out of all flavors tested, strawberry may be the ... Read More

Keeping Your Lungs Healthy During Healthy Lung Month

Although most people associate October with Breast Cancer Awareness Month, it is also known as Healthy Lung Month. The American Lung Association is publishing material all month with tips and education about how to take care of your lungs. First on the list of encouraging healthy lungs is not smoking. Cigarette smoke is a known cause of lung cancer and chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. Cigarette smoke also destroys lung tissue and can cause chronic inflammation of the lungs. E-cigarettes and other electronic nicotine delivery systems (ENDS) now have the same FDA regulation as regular cigarettes because of dangers ... Read More

‘Popcorn Lung’ Can Return After Lung Transplant

Bronchiolitis obliterans is a serious lung disease that is commonly known as “popcorn lung.” The disease got its nickname for the five microwave popcorn plant workers that developed the disease in 2000 after long-term exposure to diacetyl, a chemical used as a flavoring that mimics the creamy taste of butter. Diacetyl is a naturally occurring chemical in the coffee bean roasting process, and is often added to foods and drinks that are enhanced by a buttery flavor, such as cooking oil, cooking sprays, baking mixes, beer and flavored coffee. It has also been found in e-cigarette liquids, which raises concerns about the ... Read More

Diacetyl, Acetoin and 2,3-Pentanedione Found in 92 percent of E-Cigarettes

In the early 2000s, several workers of a popcorn plant became ill with bronchiolitis obliterans – or “popcorn lung” – after they endured long-term exposure to diacetyl, a chemical used in flavorings to mimic the creamy taste of butter. Although many major popcorn manufacturers have since taken the chemical out of their microwave popcorn, people are still at risk for exposure. Diacetyl can be found in baking mixes, candy, alcohol, flavored yogurt, snack foods, cheese, and coffee. According to the FDA, diacetyl is safe when consumed in trace amounts. But when it is inhaled, the person is at risk for developing serious lung diseases ... Read More

Vaping Community Unhappy with Harvard Study Showing Diacetyl in Majority of Flavors Tested

When a Harvard study was conducted of e-cigarette flavorings, it confirmed that 47 of the 51 flavors tested contained one of three closely related chemicals: diacetyl, 2,3 pentanedione and acetoin. The chemicals are used as flavoring agents. The study was published in Environmental Health Perspectives, a peer-reviewed journal published by the National Institutes of Health (NIH). Diacetyl and its close cousins, 2,3 pentanedione and acetoin, have been under scrutiny in recent years because of their links to serious lung diseases such as bronchiolitis obliterans, better known as “popcorn lung” because of the popcorn flavoring factory workers that were diagnosed with the disease. It’s only treatable by lung transplant, so ... Read More

NIOSH Recommends Ongoing Assessments of Hazards Associated with Diacetyl Exposure

The food flavoring industry and flavoring chemicals have been under the scrutiny of National Institute for Occupational Safety and Health (NIOSH) for the last decade. Of particular interest is the use of diacetyl, or its substitute, 2,3 pentanedione, a flavoring that produces a buttery or creamy taste, put in a wide variety of products from bakery products, microwave popcorn, and coffee to e-cigarettes. NIOSH has even published a set of “best practices” guidelines for the chemical exposure. The concern has been the potential respiratory damage linked to exposure to the chemicals. They are naturally produced during the coffee-roasting process, but it’s the grinding of the ... Read More

Texas Retail Popcorn Shop Worker Files Lawsuit Following ‘Popcorn Lung’ Diagnosis

Mary Harris worked at a popcorn shop in a Texas mall for 17 years. When she was diagnosed with an incurable lung disease called bronchiolitis obliterans, she filed a lawsuit against 54 defendants, 10 of which are related companies, all of which produce or distribute flavorings that contain diacetyl. Diacetyl is used as a flavoring agent in products such as microwave popcorn, flavored coffee, cake mixes, prepackaged frosting, and many other types of foods and is used to mimic the creamy flavor of butter. It has been linked to bronchiolitis obliterans, better known as “popcorn lung” for the five microwave popcorn plant workers that ... Read More

Texas Woman Diagnosed with Severe Lung Disease After Years of Occupational Diacetyl Exposure

Julysabel Cerda is only 35 years old and had worked at a coffee roasting plant in Texas since 2007. Part of her everyday routine was climbing the ladder to the mezzanine at the top of a grinder where coffee beans were processed. She would stir the beans, inhaling aromas that are suspected of destroying her lungs. Only a year after working there, she began to notice being increasingly winded after climbing the same ladder every day. She was fit, healthy and active otherwise. She suspected something must be wrong. A cough persisted, her throat constantly felt dry, and she couldn’t figure out why ... Read More
