Food insecurity (FI) has an impact on food intake, and it can make it difficult for people to eat enough nutritious food at all times to sustain an active and healthy lifestyle. The COVID‐19 outbreak has hampered people's capacity to obtain nutritious and affordable food. Although FI has been studied in Malaysia, the extent to which it is linked to gut microbiota has yet to be discovered. This review aimed to compile evidence of the relationship between FI and gut microbial changes and their potential relevance to a multi‐ethnic population in Malaysia. FI is typically associated with cheaper and calorie‐dense foods because of the high cost of quality food and financial constraints that hinder food‐insecure people from adopting healthier dietary choices. As a result, they have started eating low‐quality food such as simple carbohydrates, fats, and processed foods. These poor eating habits can reduce microbial diversity and influence changes in the composition and function of the gut microbiota. This review also explores the impact of ethnicity on the variation in composition of gut microbiota. In conclusion, the findings of this review may be utilized to develop and implement diet‐related intervention programs to ensure that Malaysians get enough nutritious food to maintain a healthy gut microbiota and improve overall health. Food insecurity refers to lack of access to a sufficient quantity of nutritious diets, which may influence changes in gut microbiota composition. The Covid‐19 pandemic has exacerbated the existing food insecurity in Malaysia. Thus, nutrition‐related intervention programs that focus on healthy food choices are important to establish and maintain a healthy gut community and overall health.
