Understanding Picky Eating: Causes, Effects, and Tips

Are you struggling with a picky eater at home? Mealtime feels like solving a puzzle every day, doesn't it? Your child avoids anything new, and veggies are practically invisible to them. Sound like your home? That’s picky eating! Picky eating, or selective or fussy eating, is a behaviour where individuals are uninterested towards consuming certain foods but prefer others. It's when someone only eats a small variety of foods and doesn't like trying new things.

However, picky eating is not solely a phase experienced by children; it can persist into adolescence and adulthood, impacting individuals across different age groups and life stages. This persistence highlights the need for a deeper understanding of picky eating beyond childhood and the significance of addressing it as a potential long-term concern.

Moreover, common misconceptions surrounding picky eating can lead to misunderstandings and misinterpretations. One prevalent misconception is that picky eating is a phase children will outgrow naturally. While this may be true for some, picky eating can persist into adulthood, impacting individuals' dietary habits and overall well-being.

Another misconception is that picky eating reflects a child's attempt to manipulate or control mealtime. However, picky eating often stems from complex sensory sensitivities, past negative experiences, or developmental factors rather than intentional behavior. Understanding these misconceptions is essential for providing appropriate support and intervention for individuals struggling with picky eating, regardless of age.

Causes of Picky Eating

  • Genetic Predispositions and Taste Preferences

Before knowing how to manage fussy eating, let us understand its causes. Picky eating may arise from a combination of genetic predispositions and environmental influences. Genetics determine an individual's taste preferences and sensitivity to certain flavors and textures, which can contribute to their selective eating habits.

  • Sensory Sensitivities

Additionally, sensory sensitivities are often cited as a significant cause of picky eating. Individuals may have heightened sensitivity to specific tastes, smells, textures, or visual aspects of food, making them more selective about what they eat. For example, someone with sensory sensitivities may avoid foods with intense flavors or particular textures that they find overwhelming or unpleasant.

  • Developmental Disorders such as Autism Spectrum Disorder (ASD) or Sensory Processing Disorder (SPD)

Furthermore, developmental disorders such as autism spectrum disorder (ASD) or sensory processing disorder (SPD) can significantly influence eating behaviors and contribute to picky eating patterns. Individuals with ASD or SPD may have sensory sensitivities that affect how they experience food, making them more selective or avoidant of certain foods. Additionally, the rigidity of routines and difficulty with transitions commonly seen in these disorders can further exacerbate picky eating tendencies.

Effects of Picky Eating

  • Deficiencies in Essential Nutrients:

Consistently avoiding certain food groups or types can result in deficiencies in key vitamins, minerals, and macronutrients.

  • Impaired Growth and Development:

Lack of essential nutrients can impair physical growth and development, particularly in children.

  • Delayed Cognitive Development:

Inadequate nutrient intake may lead to delayed cognitive development and hinder learning abilities.

  • Weakened Immune Function:

Poor dietary diversity can weaken the immune system, making individuals more susceptible to illness and disease.

  • Increased Risk of Illness and Disease:

Picky eaters may be at a higher risk of developing various health problems due to inadequate nutrition.

Proper nutrient intake to maintain optimal health and support the body's various physiological functions is an essential step that individuals should consider.

Tips for Managing Picky Eating

  • To manage picky eating effectively, offering various nutritious foods that include fruits, vegetables, whole grains, lean proteins, and dairy products is essential. Encouraging exposure to diverse flavors and textures from an early age can help broaden a picky eater's palate over time.
  • If picky eating persists despite efforts to diversify the diet, seeking professional support from a feeding therapist can provide valuable guidance and strategies tailored to individual needs. These experts can offer specialized interventions to address underlying causes and promote positive eating behaviors for improved nutritional intake and overall well-being.


Thus, understanding the various causes of picky eating is essential for providing practical support and intervention strategies. By addressing the underlying factors contributing to picky eating and incorporating tips for managing picky eating, individuals can work towards developing healthier and more varied eating habits.
