The natural decline in lung function over a 10-year period was slower among former smokers with a diet high in tomatoes and fruits, especially apples, according to a study from the Johns Hopkins Bloomberg School of Public Health, suggesting certain components in these foods might help restore lung damage caused by smoking.
The researchers found that adults who on average ate more than two tomatoes or more than three portions of fresh fruit a day had a slower decline in lung function compared to those who ate less than one tomato or less than one portion of fruit a day, respectively. The researchers inquired about other dietary sources such as dishes and processed foods containing fruits and vegetables—such as tomato sauce—but the protective effect was only observed in fresh fruit and vegetables.
The paper, which is part of the Ageing Lungs in European Cohorts study funded by the European Commission and led by Imperial College London, also found a slower decline in lung function among all adults with the highest tomato consumption, including those who had never smoked or had stopped smoking. The findings appear in the December issue of the European Respiratory Journal.
"This study shows that diet might help repair lung damage in people who have stopped smoking. It also suggests that a diet rich in fruits can slow down the lung's natural aging process even if you have never smoked," says Vanessa Garcia-Larsen, assistant professor in the Bloomberg School's Department of International Health and the study's lead author. "The findings support the need for dietary recommendations, especially for people at risk of developing respiratory diseases such as COPD."
For the study, the research team assessed the diet and lung function of more than 650 adults in 2002, then repeated lung function tests on the same group of participants 10 years later. Participants from three European countries—Germany, Norway, and the United Kingdom—completed questionnaires assessing their diets and overall nutritional intake. They also underwent spirometry, a procedure that measures the capacity of lungs to take in oxygen.
The test collects two standard measurements of lung function: Forced Exhaled Volume in one second, which measures how much air a person can expel from their lungs in a second; and Forced Vital Capacity, the total amount of air a person can inhale in six seconds. The study controlled for factors such as age, height, sex, body mass index,...Read more..
We know moms aren't supposed to drink alcohol during pregnancy, but could soda be just as bad? Studies are pointing to new evidence that excessive consumption of sugary drinks during pregnancy could cause health problems for the child later in life.
New research published in the Annals of the American Thoracic Society suggests that children ages 7 to 9 are more likely to develop asthma if they consumed excessive amounts of sugary drinks in early childhood - or if their mother did the same during pregnancy.
"Previous studies have linked intake of high fructose corn syrup sweetened beverages with asthma in school children, but there is little information about when during early development exposure to fructose might influence later health," said lead study author Sheryl L. Rifas-Shiman, MPH. Scientists had yet to investigate the effects of exposure before birth.
During their third trimesters, 1,068 mothers completed questionnaires detailing their food and beverage consumption. The researchers looked closely at reports of drinking soda, fruit juice, and other sweetened drinks to determine their results. They analyzed this information in the context of overall fructose consumption - including sugar consumed from food - to determine whether sugary drinks had a significant effect.
Nineteen percent of children studied ended up with asthma. Mothers who consumed sugary drinks were 63 percent more likely to have a child with asthma, and mothers who consumed overall high levels of fructose were 61 percent more likely.
The researchers hypothesize that the correlation is due to fructose's potentially inflammatory effect on the lungs.
The study results note that since this is a purely observational study, it cannot prove that the sugary drinks caused the asthma - rather, only that there is a correlation.
Additionally, the correlation involved large amounts of fructose, rather than your occasional sugary drink. Your safest bet is still to avoid drinking soda daily, along with avoiding these other 8 foods and drinks while you're pregnant.
Every year, on the third Thursday of November, smokers across the nation take part in the American Cancer Society Great American Smokeout event. Encourage someone you know to use the date to make a plan to quit, or plan in advance and then quit smoking that day. By quitting – even for 1 day – smokers will be taking an important step toward a healthier life and reducing their cancer risk.
Why We Need the Great American Smokeout
About 36.5 million Americans still smoke cigarettes, and tobacco use remains the single largest preventable cause of disease and premature death in the world. While cigarette smoking rates have dropped (from 42% in 1965 to 15.1% in 2015), cigar, pipe, and hookah – other dangerous and addictive ways to smoke tobacco – are very much on the rise. Smoking kills people – there’s no “safe” way to smoke tobacco.
Quitting smoking has immediate and long-term benefits at any age. Quitting is hard, but your patients and those that you love can increase their chances of success with help. Getting help through counseling or medications can double or triple the chances of quitting successfully. And who better to help out with your smoking cessation program then MD Spiro.

Financial rewards and personalized support can improve a smoker's chances of quitting, a new study finds.
"Our results show that a successful intervention to help [low-income] individuals quit smoking should be multifaceted and focus on both assisting with resources and, when possible, providing financial incentives," said lead author Dr. Karen Lasser. She's a general internist at Boston Medical Center and an associate professor of medicine at Boston University School of Medicine.
In the study of more than 350 adults, one group of smokers was provided a "patient navigator" to help them get prescriptions for nicotine replacement products and referrals for counseling. They were also offered a monetary reward ($250) if they quit within six months. They received an additional $500 if they were not smoking after 12 months.
Those who did not quit within six months were given a second chance to earn $250 if they quit within 12 months.
A control group of smokers was only given information about resources to help them quit smoking.
After six months, nearly 10 percent in the intervention group had quit smoking, compared with less than 1 percent in the control group. After 12 months, researchers found 12 percent of the intervention group had stopped smoking, compared with 2 percent who only received information about quitting.
"Most of the participants who quit smoking utilized patient navigation, but it's unclear whether navigation alone would achieve the rates of smoking cessation we observed," Lasser said in a medical center news release.
She and her colleagues said older smokers, women and nonwhites were most likely to benefit from the personal support and payments.
The study was published Oct. 30 in the journal JAMA Internal Medicine.

Many chronic diseases have an age dimension. As we grow older, the body’s ability to repair itself changes, and damage can accumulate in various parts of the body. Cancer, arthritis, cardiovascular disease, Type 2 diabetes, osteoporosis and dementia are all diseases that tend to afflict older adults more frequently than younger adults.
Chronic obstructive pulmonary disease also has an age component. Because this incurable and progressive lung disease usually results from years of damage to the tissues of the lungs, it’s more common in older adults. The Mayo Clinic reports that “most people are at least 40 years old when symptoms begin.” These symptoms include shortness of breath, especially when engaging in physical activity, wheezing or chest tightness, a chronic cough, lack of energy and frequent respiratory infections. These symptoms may be mistaken for simple signs of aging, but over time they will increase to the point of requiring treatment. And if it’s COPD, it’s not just age – the symptoms are being caused by real damage to the lungs that can’t be reversed but can be managed to maintain a better quality of life.
A lengthy history of cigarette smoking is the biggest risk factor for developing COPD, but the National Heart, Blood and Lung Institute reports that about 15 percent of COPD patients have never smoked. These people may have encountered occupational hazards such as coal dust or other airborne particles that damaged the lungs, or had other exposures to inhaled irritants that did permanent damage to the inside of the lungs.
Although COPD can be considered a disease of aging, there are some other factors that can lead to COPD at a younger age in some people.
One factor that can put nonsmokers and younger people at risk for developing COPD is a genetic condition called alpha-1 antitrypsin deficiency. Patients with this hereditary condition have a delivery problem with alpha-1 antitrypsin enzyme. The liver manufactures the enzyme, but it can’t exit the liver properly, so it’s not delivered to the lungs where it does most of its work. This can lead to problems with both the lungs and the liver.
“Alpha-1, for short, is primarily a genetic condition that increases the risk of things injuring the lung and liver that normally wouldn’t injure them,” says Dr. Robert Sandhaus, pulmonologist at National Jewish Health in Denver.
“People with this deficiency are 100 times more...
Flooding means health issues that unfold for years
The flooding of Texas and Florida is a health catastrophe unfolding publicly in slow motion. Much of the country is watching as gallons of water rise around the chairs of residents in nursing homes and submerge semi-trucks. Some 20+ trillion gallons of water are pouring onto the urban plain, where developers have paved over the wetlands that would drain the water.
The toll on human life and health so far has been small relative to what the images suggest. But the impact of hurricanes on health is not captured in the mortality and morbidity numbers in the days after the rain. This is typified by the inglorious problem of mold.
Submerging a city means introducing a new ecosystem of fungal growth that will change the health of the population in ways we are only beginning to understand. The same infrastructure and geography that have kept this water from dissipating created a uniquely prolonged period for fungal overgrowth to take hold, which can mean health effects that will bear out over years and lifetimes.
The documented dangers of excessive mold exposure are many. Guidelines issued by the World Health Organization note that living or working amid mold is associated with respiratory symptoms, allergies, asthma, and immunological reactions. The document cites a wide array of “inflammatory and toxic responses after exposure to microorganisms isolated from damp buildings, including their spores, metabolites, and components,” as well as evidence that mold exposure can increase risks of rare conditions like hypersensitivity pneumonitis, allergic alveolitis, and chronic sinusitis.
Twelve years ago in New Orleans, Katrina similarly rendered most homes unlivable, and it created a breeding ground for mosquitoes and the diseases they carry, and caused a shortage of potable water and food. But long after these threats to human health were addressed, the mold exposure, in low-income neighborhoods in particular, continued.
The same is true in parts of Brooklyn, where mold overgrowth has reportedly worsened in the years since Hurricane Sandy. In the Red Hook neighborhood, a community report last October found that a still-growing number of residents were living in moldy apartments.
The highly publicized “toxic mold”—meaning the varieties that send mycotoxins into the air, the inhaling of which can acutely sicken anyone—causes most concern right after a flood. In the wake of Hurricane...Read more..
Researchers analyzed data from more than 8,500 mothers-to-be who took part in an annual government health survey. It found a 2.5 percent rise in smoking rates among pregnant women with depression between 2002 and 2014.
Smoking rates among other groups fell during that time, according to the study published online in the October issue of the journal Drug and Alcohol Dependence.
"An increase in smoking rates in any population is concerning given the general overall downward trends we are seeing today," said study leader Renee Goodwin. She's an adjunct associate professor of epidemiology at Columbia University's Mailman School of Public Health.
More than a third of pregnant women with depression smoke, compared with 1 in 10 who are not depressed, according to the study.
Goodwin said the link between depression and prenatal tobacco use has increased over time, suggesting that depression is an important -- but rarely treated -- barrier to quitting smoking.
She noted that smoking during pregnancy is more common among women who are unmarried, less educated and have lower incomes. "Notably, these are also groups who often have less access to prenatal care," she added in a Columbia news release.
Goodwin said many women may be unaware that depression is interfering with their ability to stop smoking and may need extra help to quit.
"Public health campaigns to educate people about the importance of quitting smoking during pregnancy is highly recommended. Treatment for depression in conjunction with smoking cessation efforts may also be the critical component to help women succeed in quitting," Goodwin concluded.
Obese people with chronic obstructive pulmonary disease (COPD) who get weight loss surgery may go to the hospital less often with acute breathing problems after their operations, a U.S. study suggests.
Among obese adults with COPD who had what’s known as bariatric surgery to lose weight, the proportion of patients who needed emergency room or inpatient hospital care for the lung disorder fell by more than half after the operations, the study found.
“If you are morbidly obese and suffering from COPD, bariatric surgery could mitigate COPD-related symptoms,” said lead study author Dr. Tadahiro Goto, an emergency medicine researcher at Massachusetts General Hospital in Boston.
COPD is usually caused by smoking, and symptoms include breathing difficulty, cough, excessive phlegm production, and wheezing.
Treating obesity in patients with COPD is controversial because that excess weight has been linked to both worse lung function and better survival odds, Goto said by email. Recently, some small studies have suggested weight loss might benefit COPD patients, but the current study is the largest to date to provide evidence that bariatric surgery may help ease severe symptoms, Goto added.
The researchers examined data on 481 obese adults aged 40 to 65 who had COPD and underwent bariatric surgery in California, Florida and Nebraska.
They followed patients from 2005 through 2011 to see how hospital and emergency room visits for COPD in the two years before weight loss surgery compared to the two years afterwards.
At the start of the study, when patients were 13 to 24 months away from getting their operations, 28 percent of them had an emergency department (ED) or hospital visit for acute COPD symptoms, researchers report in Chest.
During the second year of the study, the 12 months right before surgery, these rates didn’t change much.
But compared with that first year of the study, the chances of an ED or hospital visit dropped by 65 percent in the first year after bariatric surgery. Just 12 percent of patients had a COPD visit during that time.
During the last year of the study, 13 to 24 months after surgery, the odds of an ED or hospital visit were 61 percent lower than in the first year of the study.
One limitation of the study is that it focused on people with severe COPD symptoms, and the results might not apply to people with well-controlled disease, the authors note.
It’s also possible that insurance might not...Read more..
