The changing face of functional foods

Area of Science:

• Food and nutrition sciences
• Nutritional biochemistry
• Public health nutrition

Background:

• Consumer perspectives on food have shifted, leading to the rise of functional foods.
• Functional foods provide health benefits beyond basic nutrition, influencing diet and health.
• The self-care movement, regulatory changes, and scientific evidence drive interest in functional foods.

Purpose of the Study:

• To define functional foods and their role in health.
• To explore the evolving landscape of functional foods in the 21st century.
• To re-evaluate traditional foods, like eggs, as functional foods.

Main Methods:

• Literature review on functional foods and dietary impacts.
• Analysis of scientific evidence regarding food components and health outcomes.
• Examination of traditional food reclassification based on new research.

Main Results:

• Functional foods are defined as foods with health benefits beyond basic nutrition.
• Eggs are identified as a functional food, debunking cholesterol concerns.
• Eggs provide essential nutrients like protein, choline, lutein, and zeaxanthin.

Conclusions:

• Functional foods are integral to modern nutrition and disease prevention.
• Eggs are a valuable functional food due to their nutrient profile and lack of adverse cholesterol effects.
• Personalized nutrition, informed by genomics, will shape future dietary approaches, with eggs playing a continued role.
