When you think of the most unbeautiful thing you can do for your body, what do you imagine? For me, it’s smoking. We’ve known for years that cigarettes decrease our lifespan, increase our risk for cancer and respiratory conditions and make our skin wrinkled and dull looking. In essence, they age us.

A new study in the journal Nicotine & Tobacco Research looked at fruit and vegetables consumption in relation to quitting smoking and found that eating healthy produce helped with not only quitting smoking but staying smoke-free as well.Eating plenty of fruits and vegetables may have increased satiety in smokers, making them less likely to smoke (smokers often confuse hunger with cravings to smoke), according to the researchers. This study and previous research have shown that fruits and vegetables actually make the taste of cigarettes worse. A 2007 study published in the journal Nicotine & Tobacco Research surveyed smokers on their food preferences in relation to their smoking habits and found that dairy products, fruits and vegetables made cigarettes taste awful, while red meat and alcohol made them taste great.
