Moving Forward: Food Access Is a Neurodiversity Justice Issue
Food should be simple. You get hungry, you eat, you plan meals, you shop for ingredients, you prepare food, you consume it, and for neurotypical people this process requires minimal cognitive effort. For AuDHD people, every single step presents neurological barriers that the world doesn’t recognize as barriers and that we’ve been taught to interpret as personal failures.
You forget to eat until you’re so hungry you can’t function. You remember to eat but can’t decide what to eat, or you decide what to eat but the texture is wrong and you can’t make yourself consume it. You want variety but also need the same safe foods. You need routine around meals but can’t maintain consistent meal times. You know you should eat vegetables but vegetables require preparation and preparation requires executive function you don’t have. You want to cook elaborate meals when you’re hyperfocused and you want someone else to just put food in front of you when you’re not.
The neurotypical world says: meal prep, plan your week, make a grocery list, cook in batches, eat balanced meals, follow a schedule. The neurotypical world doesn’t understand that every single one of these instructions requires sustained executive function, sensory tolerance, time management, and capacity for routine that AuDHD people don’t consistently have access to.
This isn’t about willpower, isn’t about caring enough about your health, isn’t about being an adult who should know how to feed yourself. It’s about neurology that makes the simple act of feeding yourself into a complex navigation of competing needs and limited capacity.
THE EXECUTIVE FUNCTION PROBLEM
Feeding yourself requires more executive function than neurotypical people realize: noticing you’re hungry, remembering that hunger means you need food, stopping what you’re doing, deciding what to eat, determining whether you have the ingredients, acquiring ingredients if you don’t, preparing the food, eating the food, cleaning up after eating the food. Each of these steps is a discrete task requiring initiation, sustained attention, and task completion, and for ADHD brains every transition between steps presents an opportunity for the entire process to fall apart.
You notice you’re hungry but you’re hyperfocused on something else so you don’t stop. You remember you need food but you can’t decide what food so you keep scrolling. You decide on food but going to get it requires standing up and your body won’t cooperate. You acquire food but preparing it feels impossible so it sits on the counter. You prepare food but by the time it’s ready you’re no longer hungry, or the hunger has become so severe you feel nauseous, and either way you’re not eating in the uncomplicated way that the advice assumes.
For autistic brains, the process requires knowing which foods are safe, having those foods available, and having the environment be predictable enough that eating doesn’t require additional sensory or cognitive resources. If your safe foods aren’t available, eating becomes exponentially harder. If the environment is too loud or too bright or too chaotic, eating may not be possible at all, and if you’re already dysregulated you may not have the capacity to eat even though you know you need to.
For AuDHD brains, you need routine around meals to reduce the executive function load and you also can’t maintain routine because your schedule is unpredictable or your interest-based nervous system means meal times disappear when you’re focused on something else. You need the same foods to be available consistently and you also get bored eating the same thing. You need preparation to be minimal and you also sometimes want to cook elaborate meals when the cooking itself is interesting. The world interprets this as not prioritizing your health or not planning ahead, when what’s actually happening is that you’re constantly trying to feed yourself and the trying is exhausting and sometimes it takes all the energy available and leaves nothing for the actual eating.
THE SENSORY NIGHTMARE
Food is sensory experience: taste, texture, temperature, smell, visual appearance. For autistic people, sensory sensitivities can make entire categories of food genuinely inaccessible, with textures that other people don’t notice being overwhelming, unbearable, physically revolting, smells that other people find mild being overpowering, foods that touch each other on the plate becoming contaminated, temperature needing to be exactly right or the food is inedible.
These aren’t preferences and they aren’t pickiness. They’re neurological responses that can’t be overridden through willpower, and when a food has the wrong texture, eating it can trigger a gag reflex, can make you feel physically ill, can be genuinely traumatic in ways that produce lasting aversion. When sensory input is already overwhelming from other sources, adding food sensory input may be completely impossible regardless of hunger.
Safe foods are foods the nervous system can tolerate: often consistent texture, predictable taste, minimal smell, reliable appearance. The neurotypical world calls these foods kid foods or boring foods or unhealthy foods and says you should expand your palate, try new things, eat variety, stop eating the same thing every day, and the neurotypical world doesn’t understand that safe foods aren’t about preference. Safe foods are about access, and that’s a significantly different thing than what the judgment implies.
The ADHD component adds another layer, because ADHD brains seek novelty and stimulation and eating the same thing every day can become so understimulating that the brain can’t engage with it. You need variety, interesting flavors and textures and combinations, foods that capture your attention enough that you can actually focus on eating them instead of getting distracted mid-meal and wandering off before finishing.
AuDHD people need safe foods that are consistent and reliable and also need variety and novelty, depending on the state of the nervous system on any given day. They need foods that don’t require sensory tolerance they don’t have and also need foods interesting enough to hold their attention. This isn’t contradiction: it’s AuDHD neurology requiring different things at different times based on capacity, regulation state, sensory tolerance, and what has attention in the moment.
THE SENSORY COMPLEXITY OF COOKING ITSELF
The sensory demands of food don’t begin at the eating, and for many autistic people cooking is its own sensory gauntlet that presents barriers before a single bite has been taken.
The smell of food cooking can be overwhelming: the particular smell of meat browning, of onions softening, of garlic hitting hot oil, of fish near a pan. For autistic people whose olfactory sensitivity means smells are processed more intensely and more persistently than neurotypical people experience them, cooking can mean spending twenty minutes in a state of sensory assault in order to produce food that then also has to be eaten, with the smell that lingers on clothing and in the kitchen afterward adding a further layer of difficulty that often isn’t part of the calculation when cooking is recommended as the obvious solution to food access.
The sounds of cooking are similarly demanding: the crackle of oil, the hiss of liquid hitting a hot pan, the noise of a food processor, the sustained background noise of a running fan or humming appliance, often in frequencies and intensities that autistic sensory processing finds specifically difficult to manage. These sounds compound across the duration of a cooking session in ways that can leave the autistic person too depleted from the cooking to manage the eating that follows.
The tactile demands of food preparation, handling raw meat, managing sticky or wet or crumbly textures, working with foods whose consistency changes unpredictably during preparation, are real barriers for autistic people whose tactile sensitivities make certain textures genuinely intolerable. Using gloves helps with some of these but introduces their own tactile issues, and the accommodation that solves one sensory problem often creates a different one.
Heat management during cooking introduces an unpredictability that autistic people who need to know how things will go find specifically difficult: a sauce that suddenly starts burning, a boil-over, the unpredictable behavior of a new recipe requiring rapid responses that executive dysfunction makes difficult. The unpredictability of cooking is one reason many autistic people prefer foods that require minimal cooking or that follow very rigid preparation sequences whose outcomes are reliably consistent.
THE INTEROCEPTION GAP
Interoception is the sense of your internal body state: hunger, thirst, pain, temperature, fatigue. Neurotypical people generally have reliable interoception, feeling hungry and recognizing it as hunger and responding accordingly. Many autistic and ADHD people have unreliable interoception, where signals are delayed or absent or confusing, where you don’t realize you’re hungry until you’re so hungry you feel sick, where you don’t recognize hunger as hunger at all and just feel vaguely bad or irritable or unable to focus.
AuDHD people often have this problem intensified, with unreliable interoceptive signals and time blindness that means you’re also unaware of how long it’s been since you last ate. You think you ate recently and it’s been eight hours. You think it’s been hours and it’s been thirty minutes. You can’t track meal timing internally so you need external structure, but you also can’t maintain external structure consistently because executive function is inconsistent.
The dangerous pattern that unreliable interoception produces is one of swinging between not noticing hunger at all and noticing it suddenly and acutely when the body has run out of patience: the shift from not hungry to overwhelmingly, urgently hungry with almost no warning, at a point where eating has become difficult because the dysregulation from not having eaten makes food preparation and decision-making harder than they already were. You’re simultaneously most in need of food and least capable of accessing it, which is a pattern that produces distress, poor eating decisions, and sometimes the beginning of a cycle that’s difficult to interrupt.
THE PLANNING AND PREPARATION BARRIER
Feeding yourself according to neurotypical standards requires planning that proceeds through a sequence of executive function demands: knowing what you’ll eat multiple days in advance, making a grocery list, shopping for ingredients, preparing meals when meal time arrives, doing all of this consistently week after week without it falling apart. For ADHD brains this is multiple layers of executive function demand that may or may not be accessible depending on what has attention and whether the task is interesting, because boring tasks don’t activate ADHD executive function and meal planning and grocery shopping are, for most people, boring.
The specific challenge of predicting what will sound appealing to future you is worth naming as its own difficulty. AuDHD people’s food preferences and capacities vary significantly based on regulation state, sensory tolerance, what’s happening in their life, and factors they often can’t predict in advance. The meal that was planned on Sunday when executive function was available and enthusiasm for cooking was present may be completely inaccessible on Wednesday when dysregulation has made the planned meal’s sensory profile intolerable or its preparation complexity impossible. Meal planning assumes a consistency of preference and capacity that AuDHD people often simply don’t have, which means meal plans fail in ways that produce shame rather than information.
For autistic brains, grocery shopping requires tolerating the sensory environment of grocery stores, navigating the unpredictability of whether safe foods will be in stock, managing social interaction at checkout, and having enough cognitive capacity left after all of that to actually prepare food when arriving home. The sensory environment of grocery stores, with their fluorescent lighting, their ambient noise, their crowds and their overwhelming mix of food smells, is one that many autistic people find genuinely depleting rather than neutral.
The standard advice of meal prep, cook everything on Sunday and eat the same thing all week, fails for many AuDHD people in a specific and predictable way: they cook on Sunday, eat the meal once or twice, get bored because the AuDHD brain needs novelty, can’t make themselves eat it again, and then have a refrigerator full of food they won’t eat while they still have no accessible food available. The shame produced by this pattern, the wasted food and the failed system and the evidence of another thing that didn’t work, is often more damaging than simply not having tried the meal prep in the first place.
THE ROUTINE PROBLEM
Autistic people often need consistent meal times because eating at the same time every day creates predictability, reduces decision-making, and helps with regulation: you don’t have to decide when to eat, you don’t have to remember to eat, you just eat at the designated time and the body adjusts to that rhythm. ADHD people often can’t maintain consistent meal times because time blindness means you don’t notice when meal time arrives, hyperfocus means you don’t want to stop what you’re doing, and interest-based attention means meals don’t feel urgent when you’re engaged with something else.
AuDHD people need consistent meal times for regulation and can’t maintain consistent meal times because of executive dysfunction and time blindness, which means they’re simultaneously craving structure around meals and unable to maintain that structure. They set alarms for meal times and then ignore the alarms because the transition away from what they’re doing isn’t possible. They build routines around breakfast and then the routines stop working because something in the execution chain has changed. They want someone else to tell them when to eat and what to eat and also resist external control over their eating, which is its own paradox that the available advice on routine-building consistently fails to address.
MEDICATION AND APPETITE
One of the most consistently underdiscussed aspects of AuDHD food access is the effect of ADHD medication on appetite, because stimulant medications, which are the most effective pharmacological treatment for ADHD, frequently suppress appetite significantly, and the interaction between medication-induced appetite suppression and already unreliable interoception can produce eating patterns that are genuinely difficult to manage.
The person who takes stimulant medication in the morning and finds that appetite disappears for most of the day is navigating a specific challenge: the medication that makes executive function more available also removes the hunger signal that would otherwise prompt eating. By late afternoon or evening, when the medication is wearing off and appetite returns, the person may be significantly depleted from an entire day of inadequate food intake, and the return of appetite in a state of depletion often produces intense hunger that’s difficult to manage calmly, leading to the kind of eating patterns that are then pathologized as disordered when they’re actually a predictable consequence of a medication management challenge that most prescribers don’t address.
Managing food intake around stimulant medication requires deliberate planning that works against the medication’s effects: eating before medication takes effect in the morning, when executive function is least available but appetite is most present; building in scheduled eating even in the absence of hunger signals during peak medication hours; planning for the evening appetite return in ways that don’t result in eating everything available at once. This is a complex management challenge that most prescribers don’t address adequately and that produces shame when it fails, because the person is blamed for not eating when the medication has removed the primary mechanism that prompts eating.
SAFE FOODS AND FOOD INSECURITY
Safe foods are what you fall back on when everything else is too hard: foods whose sensory profile the nervous system can tolerate, which are often simple, predictable, consistent. The neurotypical world judges safe foods as unhealthy, boring, childish, lacking in variety, and this judgment creates shame around something that is actually a survival strategy. You eat your safe foods and you feel like you’re failing at being an adult. You eat your safe foods and you hide what you’re eating because you don’t want people to comment on it. And yet safe foods aren’t a backup option for when you can’t eat real food: they are real food, and they’re what make eating possible when capacity for anything else isn’t available.
The fear of safe foods becoming unavailable creates a specific kind of anxiety for AuDHD people that deserves to be named as food insecurity even when financial resources are present. If your safe foods are in stock, you can eat. If they’re not, eating becomes exponentially harder or impossible. This creates constant low-level anxiety about access, about formulation changes, about discontinued products, about being in environments where your safe foods aren’t available. The neurotypical world doesn’t recognize neurological food insecurity as a real category of food insecurity because the standard framing assumes that if food is financially accessible it is therefore accessible, but for AuDHD people the neurological barriers to food access are real and significant regardless of purchasing power.
THE TEXTURE SPECIFICITY PROBLEM
Texture is often the most significant sensory barrier to food access for autistic people, and it operates with a specificity that neurotypical people find difficult to understand, because it isn’t that mushy foods in general are problematic, or crunchy foods in general, or foods with chunks: it’s that very specific textures in very specific foods are intolerable in ways that don’t generalize predictably to other foods with similar textures.
A person who can’t tolerate the texture of cooked onions in a dish may be entirely fine with the texture of caramelized onions, or raw onions, or onion rings, because the specific texture produced by each preparation method is distinct enough that the nervous system categorizes them as different sensory experiences. A person who gags on the texture of a particular brand of yogurt may be fine with a different brand whose slightly different formulation produces a texture that falls within their tolerances. A person who can’t eat scrambled eggs may be fine with fried eggs or hard-boiled eggs because the same ingredient prepared differently produces a texture that is and isn’t the same thing.
