Sugar and Mental Health: Sometimes It’s About More Than Food

Feb 18

Sugar gets blamed for a remarkable number of things: depression, anxiety, ADHD, inflammation, brain fog, fatigue, weight gain, and even addiction.

The science is more complicated than most of those claims suggest. Higher sugar consumption has been associated with depression in research, but association isn't the same as causation, and the evidence for anxiety is less clear. Sugar also isn't currently classified as an addictive substance in the way alcohol, nicotine, or opioids are.

But that doesn't mean our relationship with sugar is psychologically unimportant.

For some people, eating something sweet is simply pleasurable. For others, it has quietly become one of the most reliable ways they know to change how they feel.

And that's where the conversation becomes much more interesting.

Sometimes sugar is doing a job

Think about when you're most likely to reach for something sweet.

Maybe it's late at night, when the demands of the day are finally over. After conflict. When you're lonely. When you're exhausted but still need to function. When you're bored and need stimulation. When you've been taking care of everyone else all day and want something that feels entirely yours.

Or maybe you don't know. You just know you want it.

Sweet foods are pleasurable and rewarding. Eating them can also become associated with comfort, celebration, relief, nurturing, distraction, or escape through years of experience.

So rather than beginning with Why can't I stop eating this?, sometimes a more useful question is:

What happens right before I want it, and what changes after I have it?

If you feel anxious before eating and calmer afterward, that's information. If you feel empty and then briefly comforted, that's information too. So is realizing that you're not particularly hungry—you desperately need a break.

Trauma can become part of the story

This doesn't mean that everyone who eats too much sugar has trauma. They don't.

But for some people, food became part of emotional regulation very early.

Maybe food was comfort in a home where emotional comfort wasn't consistently available. Maybe treats were how affection was expressed. Maybe eating alone provided relief from a chaotic household. Maybe sweets became a reliable pleasure during a childhood that didn't contain enough of them.

Or perhaps the pattern developed much later. Food can become a way to manage grief, chronic stress, loneliness, relationship pain, anxiety, or the aftermath of trauma.

The behavior doesn't need to have been consciously chosen to become effective.

If your nervous system learns, over and over, I feel terrible → I eat this → something changes, that's a powerful association.

And simply removing the food doesn't necessarily address what was happening before you reached for it.

“I think I’m addicted to sugar”

People say this frequently, and I don't think the experience should be dismissed just because the science around the terminology is unsettled.

Some people describe cravings, loss of control, eating considerably more than they intended, repeated unsuccessful attempts to cut back, and continuing to eat certain foods despite consequences they care about. Those experiences can feel remarkably addiction-like.

But there is an important scientific distinction here. Researchers continue to debate whether sugar itself produces a clinically meaningful addictive process in humans, and “sugar addiction” is not currently an established psychiatric diagnosis.

There is stronger interest in the broader concept of food addiction, particularly patterns involving highly palatable, often highly processed foods. Even there, the science is evolving.

So I wouldn't tell someone, You're addicted to sugar.

But I also wouldn't respond to someone saying, I feel completely out of control around this food, with Well, sugar isn't technically addictive.

Their experience still deserves attention.

The shame cycle looks familiar

There can be a familiar rhythm:

I need this.

Then:

Why did I do that? I'm never doing it again.

Then restriction, resolve, another difficult day, another craving—and eventually the behavior returns.

The shame afterward can actually become part of what keeps the cycle going. Now there is another painful emotion to regulate.

This is one reason rigid rules don't work particularly well for everyone. Turning sugar into a forbidden substance can make some people think about it more, not less. Once they eat it, the experience becomes evidence that they've failed rather than information about what happened.

Accountability and curiosity can coexist.

You can decide that the amount of sugar you're eating isn't helping you without deciding there's something defective about you for wanting it.

Where Havening can become useful

This is where my work as a trauma therapist influences how I think about changing habits.

If eating has become one of the ways you regulate distress, taking it away leaves an obvious question:

What are you going to do with the distress?

Havening Techniques® is one of the tools I sometimes use to help clients work with strong emotional and physiological reactions. Havening uses therapeutic touch along with specific cognitive and sensory components, and clients can also learn forms of Havening to use independently.

That can be particularly useful when there's a recognizable moment in the cycle: the argument that sends you toward the kitchen, the loneliness that arrives at night, the anxiety that makes you want something immediately soothing, or the old memory or feeling that seems to activate the urge.

Sometimes we're working with the trigger itself. Sometimes we're working with earlier experiences connected to it. And sometimes we're simply helping your system find another way to come down from an activated state.

The goal isn't to make yourself calm so that you're “good” and don't eat the cookie.

It's to have more than one way to feel better.

That distinction matters.

EMDR may have a role too

When a pattern is strongly connected to trauma or specific distressing experiences, EMDR may also be useful.

For example, someone may notice that rejection reliably produces an urge to eat, drink, shop, use a substance, or engage in another behavior that provides rapid relief. If that rejection sensitivity is connected to earlier relational experiences, there may be more to work with than the present-day behavior.

Reducing the intensity of the underlying trigger can sometimes change the need for the coping strategy.

That doesn't mean EMDR or Havening is a treatment for “sugar addiction.” I wouldn't make that claim.

It means that when a behavior is being used to regulate emotional distress, working with the distress can be part of changing the behavior.

And sometimes it really is just about food

It's equally important not to psychologically analyze every cookie.

Sometimes you want something sweet because it tastes good. Sometimes you're hungry. Sometimes you've barely eaten all day. Sometimes you're surrounded by food engineered to be extremely appealing. Sometimes it's a birthday and there's cake.

Not every craving needs a childhood explanation.

There are also straightforward nutritional reasons to pay attention to added sugar. Current public-health guidance recommends limiting free or added sugars as part of an overall healthy dietary pattern. And research has found an association between higher sugar consumption and depression, although that doesn't establish that sugar itself causes depression.

Nutrition matters.

It just doesn't exist separately from psychology.

A more useful experiment

Instead of beginning with I need to quit sugar, try gathering information.

Notice when you want it. Are you physically hungry? Anxious? Angry? Lonely? Exhausted? Understimulated? Have you eaten adequately during the rest of the day? Did something happen immediately beforehand?

Then notice what the food provides.

Pleasure? Relief? Energy? Comfort? Distraction? A transition between work and home? Something to do with your hands? A reward after a difficult day?

There may be a nutritional intervention. There may be an emotional one. There may be both.

And if sugar has become one of your most reliable coping tools, the goal doesn't necessarily need to be taking it away through greater self-control.

A more sustainable goal may be understanding why you need it so much—and building enough other ways to meet that need that sugar no longer has to do all the work.
