New research shows smoking habits can be curbed with Omega-3s

omega 3Whether you’re trying to kick the habit or trying to help a loved one or a friend, there’s great new research out that links a simple supplement to curbing smoking habits.

Taking omega-3 supplements reduces craving for nicotine and even reduces the number of cigarettes that people smoke a day, according to a new study conducted at the University of Haifa. “The substances and medications used currently to help people reduce and quit smoking are not very effective and cause adverse effects that are not easy to cope with. The findings of this study indicated that omega-3, an inexpensive and easily available dietary supplement with almost no side effects, reduces smoking significantly,” said Dr. Sharon Rabinovitz Shenkar, head of the addictions program at the University of Haifa’s school of criminology department and of the psychopharmacology laboratory at Bar-Ilan, who conducted this study.

Chronic exposure to smoke-derived toxicants is the primary cause of progressive pulmonary and immune dysfunctions, as well as carcinogenesis Cigarette smoking is connected not only to cardiovascular dysfunction, immune system dysfunction and cancer, it also reduces the levels of essential fatty acids in the brain, especially that of omega-3. A deficiency in omega-3 damages the cellular structure of nerve cells and interrupts neurotransmission in areas of the brain involved with feeling pleasure and satisfaction. These areas are essential in reward and decision-making, and are very important in the process of the development, maintenance and relapseof the addiction and to the inability to stop smoking. In simpler terms, omega-3 deficiency makes it harder for the smoker’s body to deal with its craving for another cigarette. “Earlier studies have proven that an imbalance in omega-3 is also related to mental health, depression and the ability to cope with pressure and stress. Pressure and stress, in turn, are associated with the urge to smoke. It is also known that stress and tension levels rise among people who quit smoking. Despite all this, the connection between all these factors had not been studied until now,” Dr. Rabinovitz Shenkar said.

The current study adhered to a strict methodology (double-blind, randomized, placebo-controlled) and included forty-eight smokers aged eighteen to forty-five who smoked at least ten cigarettes a day during the previous year, and an average of fourteen cigarettes a day. They were diagnosed as having a moderate dependency on nicotine. In total, the average age of the participants was twenty-nine and the average age they began smoking was under eighteen (in other words, they had been smoking for an average of eleven years). The participants were divided into two groups: One group received omega-3 capsules — “Omega-3 950″ produced by Solgar who donated the capsules for the study; the second group received a placebo. The participants were asked to take five capsules a day for thirty days and in total reported taking more than ninety-four percent of the capsules. At no stage in the study were the participants asked to stop smoking.

The levels of nicotine craving and consumption were checked using a series of scales regarding various aspects related to smoking urges, such as lack of control over tobacco use, anticipation of relief and satisfaction from smoking, and to the number of cigarettes smoked each day. These levels were measured at the beginning of the study, after thirty days (of treatment) and after sixty days (i.e., thirty days after stopping to take the capsules). Each time the study participants were tested they abstained from smoking for two hours and were then exposed to smoking-related cues images in order to stimulate their craving for nicotine.

The findings show that while no difference was found between the groups at the beginning of the study, after thirty days the smokers who had taken omega-3 reduced their cigarettes by an average of two a day (an eleven-percent decrease), even though they were not asked to change their smoking habits in any way. No less important, they showed a significant decrease in nicotine craving. After another thirty days of not taking anything, cigarette cravings increased slightly but still remained significantly lower than their initial level. In other words, the craving to smoke cigarettes did not return to the baseline level even a month after stopping to take the supplement. In the meantime, the group receiving the placebo did not show any significant changes in their craving levels or in the number of cigarettes they smoked a day during the sixty days.

According to Dr. Rabinovitz Shenkar, the finding that people who were not interested in stopping to smoke showed such a significant change reinforces the assumption that taking omega-3 can help smokers to regulate their addiction and reduce their smoking. Further research will indicate whether the supplement is also effective in stopping to smoke.

FoodFacts.com knows that most in our community are exceptionally health conscious and aware. But we all know people who have had a problem quitting smoking. It’s not an easy challenge and many of those we love can’t seem to overcome their addiction. This is great information to pass on. Omega-3 supplements are relatively inexpensive and easy to incorporate into one’s lifestyle. You don’t need a prescription. You aren’t putting more nicotene into your system and you won’t be inhaling controversial ingredients. Omega-3 supplements to reduce smoking frequency — let’s make sure this one gets around!

Alcohol ‘a major cause of cancer’

alcohol-has-no-effect-on-prostate-cancer-2
About one in 10 cancers in men and one in 33 in women in western European countries are caused by current and past alcohol consumption, according to a study released on Friday.

For some types of cancer, the rates are significantly higher, it said.

In 2008, for men, 44, 25 and 33 percent of upper digestive track, liver and colon cancers respectively were caused by alcohol in six of the countries examined, the study found.

The countries were Britain, Italy, Spain, Greece, Germany and Denmark.

The study also showed that half of these cancer cases occurred in men who drank more than a recommended daily limit of 24 grammes of alcohol, roughly two small glasses of wine or a pint of beer.

The cancer rates for women in the same countries, along with the Netherlands and France, was 18 percent for throat, mouth and stomach, 17 percent for liver, five percent for breast and four percent for colon cancer.

Four-fifths of these cases were due to daily consumption above recommended limits, set for women at half the level of men.

The International Agency for Research on Cancer (IARC) has long maintained that there is a causal link between alcohol consumption and cancers, especially of the liver, colon, upper digestive tract and, for women, breast.

But few studies have tried to connect the dots across a large population between cancer rates and total alcohol consumption, or the proportion of the disease burden occurring in people who drink more than guidelines would allow.

“Our data show that many cancer cases could have been avoided if alcohol consumption is limited to two alcoholic drinks per day in men and one alcoholic drink per day in women,” said Madlen Schutze, an epidemiologist at the German Institute of Human Nutrition in Potsdam and lead author of the study.

The findings also suggest that the limits set by many national health authorities may not be stringent enough to avoid the disease, she said.

“Even more cancer cases would be prevented if people reduced their alcohol intake to below recommended guidelines or stopped drinking alcohol at all,” she said in a statement.

The results, published in the British Medical Journal (BMJ), are drawn from the so-called EPIC cancer survey of 363,000 men and women who have been tracked since the mid-1990s.

Other risk factors that might have also led to cancer — especially smoking and obesity — were taken into account, the researchers said.

Nearly 44 percent of men in Germany exceeded the 24-gramme daily limit, followed by Denmark (43.6 percent) and Britain (41.1 percent).

Among women, Germany still topped the list, with 43.5 percent of women there exceeding limit, with Denmark (41 percent) and Britain (37.7 percent) coming in second and third.
