There’s a lot of talk about food
cravings stemming from nutritional deficiencies, but research has not proved
this to be true. If you've ever been tempted to blame your chocolate urges on a
magnesium deficiency, Kimberly Snyder, a clinical nutritionist and the author
of The Beauty Detox
Power, would beg to disagree. She claims your desire for
chocolate is more likely coming from an emotional place than a biological one.
“I do believe it’s important to listen
to your body and feel what foods you are naturally drawn to,” says Snyder.
“Overall though, many common cravings are tied to emotional root causes. We
often crave foods with specific textures — crunchy, soft, creamy, or smooth —
and these textures correspond to particular emotions.”
“There are two types of hunger,”
explains Amy Gorin, RDN, of Amy Gorin
Nutrition, in the New York City area. “Homeostatic hunger, or the
physical need to eat, and hedonic hunger, the desire to eat foods for
pleasure.” For instance, she notes, “you might be craving salt when your body
actually needs it, such as after a hard workout during which you lost salt
through sweating. Or you might be craving the salty food as more of a comfort
food, since foods that tend to be salty are also ones that are higher in fat,
like potato chips, which is what we crave sometimes during hedonic hunger.”
It’s not hard to grasp the
psychological component of food cravings and how we may have been conditioned,
from childhood, to want certain foods right now. Take sweets, for instance. “Most of us grew up
with sweets being presented as a reward,” says Snyder. “The very anticipation
of a reward triggers the neurotransmitter dopamine in our brain and studies show that
regular bingeing on sugar stimulates dopamine — the ‘feel-good’ chemical,
which is very addictive.”
Or maybe you don’t have an
out-of-control sweet tooth but you still find yourself wanting to reach for the
carton of cookie dough ice cream. Snyder sees clients craving fatty foods like
ice cream and cream-laden dishes during extremely busy times, when they are
being pulled in different directions. “During these times, fat can feel
stabilizing. It’s heavy in your stomach and takes a while to digest, which can
feel like it is grounding for you,” she says.
Different cravings also appear to have
different consequences. A study published in December 2015 in
the journal Eating
Behaviors looked at the relationship between food cravings
and addictive eating. Researchers found that cravings for sweets and other
foods high in carbohydrates may be more closely linked with bingeing and other
addictive eating behaviors, while cravings for fats seem to be more closely
associated with increased body mass index.
Cravings announce themselves clearly,
but what’s behind them is complex, and various factors come into play. While
cravings aren’t always tied to emotional eating, before you reach for that
piece of cake or bowl of pasta, check to see if your emotions may be to blame —
and learn the smart ways to combat the cravings.
