Dietary Restrictions Module
The Dietary Restrictions module adds food allergies and intolerances and is designed to force sims to be more careful about what they eat. Some restrictions may cause immediate reactions after eating the wrong food, while others may build up over time and create longer term consequences if ignored.
Types of Restrictions
Not every restriction works the same way. The seven restrictions are split into two categories based on how they function.
IgE-Mediated Food Allergies
These are immune-driven allergic reactions. Eating a trigger ingredient causes a fairly immediate response. Symptoms can escalate quickly and, in the most severe cases, can become life-threatening.
Non-IgE Immune Responses and Intolerance-Style Restrictions
These do not behave like a standard allergic reaction. Symptoms tend to build more gradually and involve digestive discomfort, immune responses, or longer-term health consequences if the restriction goes unmanaged. Reactions are less sudden but can become more serious over time if ignored.
Restrictions Included
IgE-Mediated Allergies
Restriction | Foods to Avoid |
Fish Allergy | All types of fish and seafood |
Nut Allergy | Tree nuts and peanuts |
Egg Allergy | Eggs and egg-based ingredients |
Soy Allergy | Soy-based ingredients including tofu and stir fry |
IgE-Mediated (Temporary)
Restriction | Foods to Avoid | Description |
Alpha-Gal Syndrome | Red meat including beef, pork, lamb, and venison | A tick-triggered allergy to a sugar found in red meat and some animal products. Unlike the other IgE conditions, this one is acquired through a Lone Star Tick bite and is only temporary. |
Non-IgE Restrictions
Restriction | Foods to Avoid | Description |
Celiac Disease | Gluten-containing foods including bread, pasta, flour-based recipes, and beer | An autoimmune condition triggered by gluten. Damage builds gradually with repeated exposure rather than causing immediate reactions. There is no anaphylaxis risk but long-term ignored exposure has serious consequences. |
Lactose Intolerance | Foods containing lactose | Symptoms are digestive rather than immune-driven. This restriction uses EA’s existing lactose intolerance system. |
How Does a Sim Get A Food Restriction?
Dietary restrictions can be assigned in three ways. You have full control over how realistic, random, or story-driven restriction gameplay feels in your save.
You can choose how allergies are assigned in the settings menu. If you prefer full control, you can assign them manually. If you want something closer to how allergies actually work in real life, you can switch to automatic mode.
Automatic Assignment
In automatic mode, food allergies are triggered by catalyst events. This will mimic real life where adults only develop food allergies after physical or mental trauma. In this mod this will also occur on a chance basis.
Inheritance
Some dietary restrictions can be inherited through family gameplay. If a sim is born having inherited their parents restriction, there is a higher chance of this restriction manifesting as that sim ages.
Manual Assignment
Players can manually assign dietary restrictions through the My Dietary Life Settings Menu at any time.
Through the settings menu, you can assign a discovered restriction if you want the Sim and player to know about it immediately, assign an undiscovered restriction if you want the Sim to find out through gameplay, remove a current restriction if you no longer want the Sim to have it, and manage inherited restriction settings where supported.
Allergic Reaction Severity
When a Sim eats something that conflicts with their restriction, they may have an allergic reaction. Reaction severity differs based on the current sim’s mood, hunger levels, tired levels, sickness, and multiple other factors that provide a weighting that determines how severe a sims reaction
The first signs that something is wrong. Symptoms include extreme itchiness.
More noticeable symptoms include nausea and eye swelling.
More intense symptoms include swollen eyes and lips, difficulty breathing, and nausea.
A life-threatening reaction where your Sim will start choking. Applies to IgE-mediated allergies only. If your Sim does not receive medication in time, they can die.
Reaction visuals are designed to display accurately across both light and dark skin tones.
Anaphylaxis and Death Settings
Anaphylaxis gameplay can be enabled or disabled through the My Dietary Life Settings Menu. If anaphylactic death is disabled, severe reactions can still be serious but will not kill your Sim. If it is enabled, severe reactions may become fatal if the Sim does not receive help in time. This setting lets you decide whether restriction gameplay feels high-stakes or more manageable depending on your playstyle.
Diagnosis
Restrictions can be discovered or undiscovered. A discovered restriction means the Sim and player already know about it. An undiscovered restriction means the Sim has the condition but has not been diagnosed yet.
If your Sim keeps reacting to certain foods and you are not sure why, they will not figure it out on their own.
To get a diagnosis, book an appointment through your Sim’s phone to visit an Immunologist and take a skin prick test.
Once diagnosed, your Sim will receive a prescription for appropriate medication.
After the appointment, your Sim will have a visible mark on their arm from the test that fades over a couple of days.
If you have Healthcare Redux installed, the Immunologist diagnosis will also generate a prescription that allows you to purchase EpiPen medication for severe and anaphylactic reactions.
Medication and Treatment
If Adeepindigo Healthcare is NOT installed
The Core Medication Kit is available to all players regardless of which mods you have installed. It is a standalone set of over-the-counter products available under the Plumbfizer brand, purchased through the computer. No prescription needed.
Product | What It Does |
ScratchNoMore Cooling Gel | Topical gel for quick relief from itch and skin irritation |
Toilet Truce Tablets | Anti-diarrheal and anti-nausea formula for mild to moderate food reactions |
MealGuard Enzyme Capsules | Pre-meal enzyme supplement for Sims with gluten or lactose sensitivities |
NapTrap Allergy Tablets | Oral antihistamine for mild to moderate allergy symptoms, known to cause drowsiness |
For severe and anaphylactic reactions, the Core Medication Kit will not be enough. If your Sim has a serious reaction and you do not have Healthcare Redux installed, you will need to send them for emergency care. This is the base treatment path for managing life-threatening reactions without the full mod.
If Adeepindigo Healthcare is installed
The Core Medication Kit is still available and can be used alongside Healthcare Redux. When adeepindigo’s Healthcare Redux is installed, additional treatment options also become available.
EpiPen
When your Sim is diagnosed by the Immunologist, they will receive a prescription that allows them to purchase an EpiPen from Adeepindigo’s pharmacy. The EpiPen can be administered directly from your Sim’s inventory during a severe reaction and will fully treat it.
Two additional products also become available through the pharmacy for mild and moderate reactions:
- Histamine Medication — for managing allergic symptoms at mild and moderate tiers
- Eczema Cream — for treating skin-related symptoms from mild and moderate reactions
How Other Sims React
Allergic reactions do not go unnoticed. When visible symptoms appear, nearby Sims will respond. How they react depends on their personality and their relationship with the affected Sim. A close friend may show genuine concern. A stranger or a less caring Sim might react very differently.
The Dietary Restrictions module adds a set of food allergy and restriction focused social interactions. These let Sims communicate about their restrictions, react to how others handle them, and support each other during difficult moments.
Celiac Disease
Celiac Disease behaves differently from the IgE-mediated food allergies in this module. It is an autoimmune condition, not an allergy, and has its own reaction system, treatment path, and long-term consequences.
Celiac Disease has three severity tiers with no anaphylactic tier.
Tier | Symptoms |
Mild | Bloating and mild stomach discomfort |
Moderate | Cramps, diarrhea, and fatigue |
Severe | Intense digestive distress, brain fog, and joint pain |
Diagnosis and Ongoing Care
When a Sim is diagnosed with Celiac Disease at the Immunologist, they are referred onward to a Gastroenterologist. Sims can book follow-up appointments with the Gastroenterologist via their phone to receive checkups and monitor the long-term impact of gluten exposure on their body.
Medication
Celiac Disease does not use antihistamines or an EpiPen. Two products from the Plumbfizer Core Medication Kit are useful for managing symptoms:
- MealGuard Enzyme Capsules — take before a risky meal to help reduce the impact of accidental gluten exposure
- Toilet Truce Tablets — for relief from nausea and diarrhea after a gluten reaction
Long-Term Effects
If a sim continues to eat foods containing gluten this leads to cumulative Intestinal Damage that builds over time.
Long-term effects include:
- Reduced focus and energy
- Significant weight loss
- Dehydration
- Infertility risk with continued exposure (requires Lumpinou’s RPO)
- Increased lymphoma risk with continued exposure (requires Healthcare Redux Patreon version)
Cross-Module Feature: Liquid Diet Recommendation
Celiac Disease connects with the Dietary Lifestyles module. If a Sim with Celiac Disease has had repeated or excessive gluten exposure, their Gastroenterologist may recommend temporarily following a Liquid Diet as part of their recovery pathway.
When the recommendation comes through, you can choose whether to follow it.
Alpha-Gal Syndrome
Alpha-Gal Syndrome is unlike any other restriction in this module. It cannot be inherited, it is not assigned through automatic restriction settings, and it is the only restriction here that is temporary. If your Sim gets Alpha-Gal Syndrome, they will recover after 4 days.
Alpha-Gal Syndrome is a rare red meat allergy caused by a Lone Star Tick bite. The tick introduces a sugar molecule into the Sim’s system that triggers an immune response whenever they eat red meat afterward.
Foods to Avoid
Sims with Alpha-Gal Syndrome need to avoid red meat for the duration of the allergy. This includes beef, pork, and lamb. Poultry is not affected, so chicken and turkey remain safe. Fish and seafood are also unaffected.
Reactions and Treatment
Alpha-Gal Syndrome follows the same four-tier reaction systems and treatments as the other IgE-mediated allergies in this module.
How It Is Triggered
When your Sim spends time outdoors in one of the high or medium risk worlds, there is a chance they may experience a Lone Star Tick bite. If this happens, your Sim will receive a notification letting you know. The restriction will then become active and your Sim will need to avoid red meat for the next 4 days until they recover.
Highest Risk Worlds
Lone Star Ticks are associated with wooded, grassy, rural, and outdoor environments. Risk levels across Sims worlds are mapped based on how closely each world matches those conditions.
**Tip – Insect Repellent does help prevent this.
Risk Level | Worlds |
High | Willow Creek, Granite Falls, Brindleton Bay |
Medium | Moonwood Mill, Chestnut Ridge |
Low | Forgotten Hollow, Glimmerbrook |
Food Safety Checks
Sims with a dietary restriction can check food labels before eating to verify whether a dish is safe.
Autonomous food interactions are also disabled for Sims with an active restriction by default, so they will not wander off and eat something they should not. This can be toggled in the settings menu if you want to add some chaos to your gameplay.
AllergySafe Caterer
There is a hireable AllergySafe Caterer NPC who players can hire to cook foods to suit all allergy restrictions. If sim hosts or is invited to a party/event they can complain about the lack of allergy safe foods and ask host to cater to their dietary needs through hiring an allergy safe caterer
Settings Menu
The My Dietary Life Settings Menu is where all dietary restriction management happens.
Setting | What It Does |
Assign Discovered Restriction | Gives a Sim a known allergy, intolerance, or restriction |
Assign Undiscovered Restriction | Gives a Sim a hidden restriction to be discovered through gameplay |
Remove Current Restriction | Removes a Sim’s current dietary restriction |
Remove Inherited Genetics | Removes a Sim’s current inherited dietary restriction |
Toggle Anaphylactic Death | Controls whether severe allergic reactions can become fatal |
