Overview: the food matrix and its role in the diet

Area of Science:

• Nutrition Science
• Food Science
• Dietary Research

Background:

• The food matrix, encompassing physiochemical structure and constituent interactions, is increasingly recognized for its health implications.
• This article introduces the concept of the food matrix within a collection focusing on dairy's role in diet and health.
• It sets the stage for understanding specific matrix effects of dairy products like milk, cheese, and yogurt.

Purpose of the Study:

• To introduce the concept of the food matrix and its importance in diet and health.
• To contextualize subsequent articles on the dairy food matrix.
• To highlight research gaps and guide future investigations.

Main Methods:

• Literature review and synthesis of current knowledge on the food matrix.
• Discussion of processing effects on the food matrix and health outcomes.
• Characterization of food matrix complexity, including dairy fat and ultra-processed foods.

Main Results:

• Processing significantly alters the food matrix, influencing its impact on diet and health.
• Nutrient contributions are better understood within the context of the whole food matrix rather than in isolation.
• Current research reveals complexities and controversies, such as those surrounding dairy fat and ultra-processed foods.

Conclusions:

• The food matrix plays a critical role in mediating the relationship between food, diet, and health.
• Further research is needed to fully elucidate the food matrix's influence, particularly concerning dairy products.
• Translating current food matrix research into practical consumer advice on whole foods and dietary patterns is recommended.
