ARFID in Adults: Not Just Picky

Were you called a "picky eater" growing up? Maybe you still hear it at family dinners, on dates or at work lunches.

If so, I want you to hear this first: nothing is wrong with you. Your brain experiences food differently. And there is language, and support, for that.

If you've searched for "picky eating in adults" or "selective eating," you're in the right place. Let's talk about what's really going on, without the shame.

In a hurry? Here's the short version

Sensory-driven eating means textures, smells, tastes and other food details come through "louder" for your brain. ARFID (Avoidant/Restrictive Food Intake Disorder) sits at the more challenging end of that spectrum, where eating enough feels hard. It's common in autistic and ADHD adults. Support starts with your safe foods, not with forcing new ones.

Feeling overwhelmed? Start here 💚

Only have energy for one thing today? Keep one safe food somewhere you can easily reach it, like your desk, your bag or your car. That's it. That counts.

I've Been There Too

I'm a registered dietitian. I'm also autistic and ADHD. And growing up, I was definitely called picky.

My first big texture challenge was meat. The texture and the chewiness were too much for me. It affected my nutrition, and it made eating with my family hard.

I was diagnosed late. So for years, I didn't have the language to explain what was going on. I just knew certain foods felt impossible, and that I was "supposed" to eat them anyway.

Today, one of my favorite safe foods is a bagel. Simple. Predictable. Safe. 🥯

If any of that sounds familiar, you're in good company. Let's lean into what's really going on.

What Is Sensory-Driven Eating?

Here's how I explain it to clients.

For some people, it's turned way up. Textures, smells, tastes, temperatures and even how food looks come through louder. A crunchy food that changes texture, a sauce touching another food, or a new brand of a familiar food can feel like a lot.

That's sensory-driven eating. It isn't a preference or a phase. It's how your nervous system takes in food.

Where ARFID fits

I see ARFID as one point on the sensory-driven eating spectrum. It's the more extreme, more challenging end, where the volume is so loud it gets in the way of eating enough, and where someone may need guidance and support.

ARFID usually shows up in one or more of these ways:

• 🎚️ Sensory: certain textures, smells, colors or tastes feel overwhelming
• 🚨 Fear-based: worry about choking, vomiting or getting sick makes eating feel unsafe
• 🔋 Low interest: food isn't on your radar. You forget to eat, feel full fast or rarely feel hungry

Many adults experience more than one. Researchers use these same three profiles to understand ARFID (Kambanis et al., 2024).

Why it's common in autistic and ADHD adults

ARFID and autism often show up together. A 2023 review found that sensory sensitivities and food routines that start in childhood often continue into adulthood, even though most research still focuses on kids (Keski-Rahkonen and Ruusunen, 2023).

A 2025 study of adults found that being more sensitive to sensory input was linked to more ARFID symptoms, even after accounting for autistic and ADHD traits (Thomas et al., 2025).

In other words: the volume knob is real.

Why I Don't Use the Word "Picky"

That word carries a lot of weight. For many people, it brings up food shame, guilt and even trauma, often from family meals or childhood.

Here's what happens in the body:

1. Someone comments on your plate, or pressures you to "just try it."
2. Shame and stress kick in. You feel unsafe.
3. Your nervous system shifts into fight or flight mode.
4. Fight or flight makes eating and digestion even harder.

So pressure doesn't help you eat more. It often makes eating harder. That's why I use the words sensory-driven eating instead.

Where It Shows Up in Adult Life

Sensory-driven eating doesn't stay at the childhood dinner table. Here's what I hear from adults all the time:

"I'm embarrassed to eat in front of people."

It can show up in:

• 🍽️ Restaurants: unfamiliar menus, surprise ingredients and dishes that don't come out the way you expected
• 🦃 Holidays: big family meals, traditional foods and comments about what's on your plate
• 💕 Dates and other close, intimate meals, where eating feels very visible
• 💼 Work lunches and events, where food is social and hard to avoid

For many of my clients, restaurants and holidays are the hardest of all. If that's you, you're not alone, and it makes complete sense.

2 Myths I Want to Bust

Myth 1: "They'll eat when they're hungry enough"

This is one of the most harmful myths out there.

So many people I work with tell me about being hungry and still not being able to get what their body needs. Hunger doesn't turn the sensory volume knob down. When safe foods aren't available, people go without the nourishment they need.

The answer isn't waiting for hunger to "win." It's making sure safe nourishment is available.

Myth 2: "The goal is always to eat more foods"

People are often surprised when I tell them this: I don't assume that adding more foods is everyone's goal.

For some people, the goal is feeling safe and fueled with the foods they already eat. For others, it's being able to eat at a restaurant or a holiday dinner with less stress. And for some, trying new foods matters to them, and that's great too.

You get to decide what your goal is.

Working With an ARFID Dietitian: What Support Looks Like

As an ARFID dietitian, I use a gentle 3-phase approach. You stay in charge the whole time.

1. Understand your sensory patterns: we map what makes eating hard, without judgment
2. Fuel your body with foods you already eat: your safe foods are the foundation, and we make sure they meet your nutrition needs first
3. Gently expand, at your pace: only if and when you want to, using small, low-pressure steps

Food chaining: tiny steps, your pace

If you do want to try new foods, one tool I use is food chaining. It's like building a roadmap from a food you already trust to a food you'd like to try, one tiny step at a time.

Here's an example, from chicken nuggets to grilled chicken strips:

1. Your favorite chicken nugget brand
2. A similar brand
3. An unfamiliar brand
4. A different nugget with less breading
5. Looking at grilled chicken strips
6. Plating them
7. Smelling them
8. Maybe taking a bite

You can pause, stay on one step for as long as you need, or go back. Every step counts, even if you never reach step 8.

What support is not

• I will never force you to eat anything that feels unsafe
• I will never shame your safe foods
• I will never rush your progress
• I will never use your weight as the measure of your health

You Might Relate If You...

• Eat a small list of safe foods, and new foods feel impossible
• Have strong reactions to certain textures, smells or tastes
• Feel anxious eating out, traveling or eating with others
• Feel tired or run down from eating the same few foods
• Have carried shame or embarrassment about how you eat

This isn't a diagnosis. It's a gentle starting point. If it sounds familiar, nothing is wrong with you. You deserve support that fits your brain.

Your Safe Foods Are Allowed

If you take one thing from this post, let it be this: your safe foods are allowed.

There is real power in getting permission to eat in a way that works for you and your brain. Not the way a family member, a diet or a meal plan says you should. Your way.

That's where healing starts. 💚

ARFID and Sensory-Driven Eating: Quick Questions

Can adults have ARFID?

Yes. Many adults live with ARFID for years before learning there's a name for it, especially people who were diagnosed autistic or ADHD later in life.

Is ARFID the same as picky eating?

No. I see ARFID as the more challenging end of a sensory-driven eating spectrum, where avoiding foods affects your health, energy or daily life. And that label often adds shame that makes eating harder.

What does an ARFID dietitian do?

An ARFID dietitian helps you get the nourishment you need while respecting your sensory needs. We start with your safe foods, fill nutrition gaps gently and only explore new foods if and when you want to. With your permission, I also work alongside your therapist and medical team.

Will you make me eat foods that scare me?

Never. We start with your safe foods, and you decide if and when to explore new ones.

Do I need a diagnosis to work with you?

No. If food feels limited or stressful, you're welcome here.

Is ARFID nutrition support covered by insurance?

Often, yes. I accept Aetna, Blue Cross Blue Shield, Cigna and UnitedHealthcare through Nourish, and most clients pay $0.
