EXPLAINER | What do your food cravings actually mean?

Craving certain foods, like chocolate or chips, is a common occurrence. However, when these cravings become frequent and lead to poor eating habits, they could have negative health effects in the long run. Health-e News interviewed registered dietitian Jandri Barnard to understand the reasons behind food cravings, when they may become problematic, and how to manage them effectively.

Food cravings are intense desires for specific foods, typically sweet treats, salty snacks, or carbohydrates. These cravings are a mix of biological and psychological factors, including stress, tiredness, lack of sleep, hormonal changes, and emotional wellbeing. Despite popular belief on social media, craving a specific food does not necessarily indicate a nutritional deficiency.

For instance, chocolate cravings may not be due to a magnesium deficiency, as the cravings are often driven by the food's sugar, fat, and texture that activate the brain's pleasure centers.

There are, however, exceptions to this rule. Pica is a condition where individuals crave or eat non-food items like ice, dirt, or clay. This can sometimes be linked to anemia or a deficiency in iron or zinc. When it comes to health concerns, occasional cravings are typically not a major issue. However, if cravings persist, cause a loss of control, become a preoccupation, or interfere with daily life, they could signal a problem.

Prolonged unhealthy eating habits can impact brain chemistry and hormone balance, potentially leading to chronic diseases like type 2 diabetes, heart disease, obesity, and gastrointestinal issues such as constipation and non-alcoholic fatty liver disease.

To manage cravings, one should first recognize their triggers. Stress, tiredness, and boredom are often linked to cravings. By identifying these triggers and finding alternative coping mechanisms, individuals can better control their cravings. Eating regular meals, staying hydrated, getting enough sleep, and including protein and fibre in meals can also help regulate hunger and blood sugar levels.

If cravings are persistent, uncontrollable, or affecting daily life, it is advisable to seek help from a healthcare professional.
