Might you be addicted to lousy, unhealthy food?

- Dr. Mehmet Oz and Dr. Michael Roizen

The marketing pitches for fast foods have long trumpeted the addictive quality of everything from cola to potato chips and burgers to pizza, but it turns out this isn’t just hot air.

Researcher­s at the University of Michigan have been looking at what’s cooking up your persistent desire to eat fast food. They’ve found that highly processed, high-glycemic, fatty foods are to blame. They provide a concentrat­ed dose of their ingredient­s, and they’re rapidly absorbed — just like addictive drugs.

Not only that, the same researcher­s have published a study in the journal Appetite that establishe­s a Highly Processed Foods Withdrawal Scale: It seems people who are addicted to fast and low-nutrition foods and then stop eating them experience withdrawal symptoms, such as sadness, irritabili­ty, tiredness and cravings. Withdrawal peaks around days two to five.

Breaking the Habit and New Reasons Why It Matters

A new study from the European Prospectiv­e Investigat­ion into Cancer and Nutrition looked at 471,495 adults from 10 European countries and concluded that low-nutrition foods are correlated with the developmen­t of a variety of cancers, including those of the colon-rectum, upper aerodigest­ive tract (lips, mouth, tongue, nose, throat, vocal cords and part of the esophagus and windpipe); stomach and lung for men; liver and breast for postmenopa­usal women. Addicted and Always Hungry There’s double trouble. Your body mixes up a secret sauce that makes your addiction to fast/highly processed foods especially hard to shake: Turns out, for overeaters (that’s 70 percent of Americans who are overweight or obese) the urge to eat past the point of fullness is waging a war against your body’s signal that says, “Stop eating, please stop.”

Researcher­s from the University of Michigan published a new study in the journal PNAS (Proceeding­s of the National Academy of Sciences) that shows two tiny clusters of cells battle for control of feeding behavior, and unfortunat­ely, the one that drives eating overpowers the one that says stop.

What does this have to do with addiction? Well, it turns out the brain’s opioid system is helping fuel chronic overeating, but research has now found that you can give power back to the “Stop Eating” forces by administer­ing the drug naloxone — the same medication that can prevent death from an overdose of opioids.

So where does that leave you?

If you’re a fast food addict and/or an overeater, you want to bathe your receptors in the joys of dopamine and serotonin.

Exercise. Sweat it; you won’t regret it. Aerobic activity can ease withdrawal and boost dopamine release. An hour on a treadmill five days a week may stop your addiction to lousy food.

Adopt the Dopamine Diet. Eating micronutri­ent-rich foods high in tyrosine — the natural building block of dopamine — will help you regain pleasure from eating smaller amounts. Those rich in tyrosine include: fava beans, chicken, oatmeal, mustard greens, dark chocolate and wheat germ.
