Craving an Ice-Cream Fix

on living well.
The notion that
food can be addictive has been debated for some time and largely rejected by
both nutrition and addiction researchers. But this spring, the secretary of
health, Kathleen Sebelius, said that for some, obesity is “an addiction like
smoking.” One month earlier, Dr. Nora Volkow, director of the National
Institute on Drug Abuse, gave a lecture at Rockefeller University, making the
case that food and drug addictions have much in common, particularly in the way
that both disrupt the parts of the brain involved in pleasure and self-control.
Princeton
University and University of Florida researchers have found that sugar-binging
rats show signs of opiatelike withdrawal when their sugar is taken away —
including chattering teeth, tremoring forepaws and the shakes. When the rats
were allowed to resume eating sugar two weeks later, they pressed the food
lever so frantically that they consumed 23 percent more than before. Scientists
in California and Italy last year reported that the digestive systems of rats
on a fatty liquid diet began producing endocannabinoids, chemicals similar to
those produced by marijuana use.
Earlier this
year, scientists at the Oregon Research Institute conducted brain-scan studies
on children who looked at pictures of chocolate milkshakes and later consumed
shakes. Their findings suggest that just as drug abusers and alcoholics need
increasingly larger doses over time, children who are regular ice-cream eaters
may require more and more ice cream for the reward centers of their brains to
indicate that they are satisfied.
Dr. Pamela
Peeke, assistant professor at the University of Maryland and author of “The
Hunger Fix,” says that meditation and exercise can help engage the brain to
overcome food addiction. As a heroin user might rely on methadone to alleviate
withdrawal, food addicts, she says, should seek alternatives that still give
pleasure — a fruit smoothie, for example, instead of ice cream.
Food addiction
seems to be linked to the types of foods we’re consuming. Dr. Kelly D. Brownell,
director of Yale’s Rudd Center for Food Policy and Obesity, notes that the
human body is biologically adapted to deal with foods found in nature, not
processed foods.
“We don’t abuse
lettuce, turnips and oranges,” says Dr. Brownell, co-editor of the new book
“Food and Addiction.” “But when a highly processed food is eaten, the body may
go haywire. Nobody abuses corn as far as I know, but when you process it into
Cheetos, what happens?”
Dr. David A.
Kessler, the former F.D.A. commissioner, described these products as
“hyperpalatable” foods created to tantalize our taste buds by focusing on the
right combination of salty, sweet and fatty ingredients along with
“mouth-feel.”
Dr. Brownell
says that the brain science should lead us to question how food companies are
manipulating their products to get us hooked. “With these foods, personal will
and good judgment get overridden. People want these foods, dream about these
foods, crave them.”
Are you addicted to food?
