A sensory-friendly diet refers to a tailored approach to nutrition designed to accommodate individuals with sensory sensitivities, such as those seen in people with sensory processing disorder (SPD), autism spectrum disorder (ASD), or other sensory-related challenges. These individuals may experience heightened or reduced responses to sensory stimuli like taste, texture, smell, and the appearance of food. The goal of a sensory-friendly diet is to ensure balanced nutrition while taking these sensitivities into account, making mealtime a more positive experience for those who struggle with food aversions or cravings related to sensory processing issues.

For individuals with sensory issues, food-related challenges often revolve around texture, flavour, temperature, or appearance. These sensitivities can cause distress, limiting food choices and leading to restricted diets, which can increase the risk of nutritional deficiencies (Cermak et al., 2010).

• Texture Sensitivity: Some individuals may avoid certain textures like mushy, slimy, or crunchy foods. For example, a child might refuse mashed potatoes but accept crackers.
• Flavour Sensitivity: Strong flavours, such as spicy or sour foods, might be overwhelming, while others may crave intense flavours.
• Temperature Sensitivity: Individuals may prefer either extremely hot or cold foods, avoiding those that fall between these extremes.
• Visual Sensitivity: Food appearance can be a significant factor, with some individuals rejecting foods based on colour, size, or shape.

1. Offer a Variety of Textures A sensory-friendly diet should include a range of textures to accommodate preferences while ensuring balanced nutrition. For example, if an individual struggles with crunchy textures, try offering foods with a smoother consistency like purees or soft-cooked vegetables. Gradually introduce new textures in small amounts to help expand their palate (Bandini et al., 2010).
2. Introduce New Foods Gradually Introducing new foods can be overwhelming for individuals with sensory sensitivities. To help with this, present new foods gradually and in familiar settings. Pair new foods with textures or flavours the individual already enjoys. This technique, known as food chaining, can encourage acceptance of new items by creating positive associations (Kuschner et al., 2015).
3. Experiment with Flavours While many individuals with sensory issues avoid strong flavours, others may seek out intense tastes like sour, salty, or spicy. Catering to these flavour preferences can increase food acceptance. For example, offering mildly seasoned versions of commonly rejected foods can help expand variety. In addition, using flavour enhancers like herbs and spices may help make food more appealing for those who prefer stronger tastes (Nadon et al., 2011).
4. Temperature Modifications Some individuals with sensory sensitivities prefer foods served at specific temperatures. For those who struggle with temperature, offering choices such as chilled fruits, warm soups, or room-temperature snacks can help ensure that meals remain appealing.
5. Smooth and Consistent Presentation Visual sensitivity to food can also be an issue, particularly with children. Offering food in a visually appealing and consistent way can reduce anxiety around new meals. Cutting food into familiar shapes or arranging it on the plate in an organised manner can make a difference.
6. Use Sensory Breaks During Meals Sensory overload during mealtime can increase aversion. Allowing sensory breaks—short intervals where the individual steps away from the table to engage in calming activities—can help reduce stress and improve overall food intake.

Restricted diets due to sensory issues can lead to nutritional deficiencies if certain food groups are consistently avoided. It’s essential to ensure the diet remains balanced. Some considerations include:

• Ensure Proper Macronutrient Intake: Sensory-sensitive individuals may reject protein-rich foods like meat or eggs due to texture or taste. In such cases, explore alternative protein sources such as smoothies with added protein powder or dairy products like yogurt.
• Incorporate Healthy Fats: Some textures associated with fat-rich foods may be challenging. However, nut butters, avocados, and smooth, creamy dairy products can provide essential healthy fats.
• Supplementation: In cases of extreme food aversion, supplementation with vitamins and minerals may be necessary to address deficiencies. Consulting with a dietitian can help create an optimal plan.

In addition to modifying the diet, creating a sensory-friendly mealtime environment can reduce stress and increase acceptance of food:

• Minimise sensory distractions: Reduce background noise, bright lights, or other distractions that may overwhelm the individual.
• Introduce predictable routines: Having a consistent mealtime schedule can help reduce anxiety and foster a positive association with eating.
• Offer choices: Allowing the individual to choose from a limited selection of foods can give them a sense of control, which may reduce anxiety and increase their willingness to try new foods.

A sensory-friendly diet is designed to meet the unique needs of individuals with sensory processing issues, focusing on offering a variety of food choices that accommodate texture, flavour, and appearance sensitivities. By understanding the underlying causes of food aversions, introducing new foods gradually, and creating a supportive mealtime environment, parents, caregivers, and professionals can help ensure balanced nutrition while reducing mealtime stress.

Here are some sensory-friendly recipe ideas that can help accommodate texture, flavour, and visual preferences, while providing balanced nutrition:

Smoothie bowls are a great way to pack in fruits and vegetables in a texture-friendly form. They offer a smooth consistency and can be customised with different flavours and nutrient-dense ingredients.

• Base: Blend frozen bananas, berries, and spinach with almond milk or yogurt.
• Toppings: Add smooth toppings like nut butter or crunchy options like granola depending on the individual’s texture preferences.

For individuals who prefer soft textures, mashed sweet potatoes are a nutritious and easy-to-prepare option. They can be sweetened slightly or seasoned with mild spices.

• Method: Boil the sweet potatoes until tender, then mash with butter and seasoning to the preferred consistency.

These baked or steamed chicken meatballs provide protein in a soft, easy-to-chew form. They can be made with various herbs to introduce new flavours without being overwhelming.

• Ingredients: Ground chicken, breadcrumbs, egg, mild spices like oregano or parsley.
• Method: Mix ingredients, form into small meatballs, and bake until fully cooked.

For children who like chewy textures, homemade fruit gummies can offer a sensory-friendly and healthy alternative to store-bought sweets.
