Food Additives: Emerging Detrimental Roles on Gut Health.

Processed and ultra-processed foods have become dietary staples in many developed countries. A major constituent of these foods is a variety of synthetic chemical additives, which are used to improve the texture, preservation, and aesthetics of food. Evidence is mounting that synthetic chemicals used as food additives may have harmful impacts on health. Studies have linked certain additives to health conditions such as attention deficit hyperactivity disorder, cancer, and obesity. In addition, emerging evidence suggests that additives, such as emulsifiers, artificial sweeteners, colorants, and preservatives, may act as potential disruptors of intestinal homeostasis. Indeed, various studies have identified that food additives can impact gut health by modulating gut microbiota and intensifying intestinal inflammation. Considering the lack of known nutritional benefits of these additives and the accumulating evidence on the detrimental effects of these additives on gut health, further experimental, epidemiological, and clinical evaluations are imperative. This will provide significant advances in the prevention and management of gut health, including intestinal inflammation, and in enriching public knowledge on the harmful effects of these additives. In this review, we explore the effects of popular food additives on gut health with a particular focus on intestinal inflammation and examine the broader implications of these impacts on food safety policy and public health.
