Ancient Grains as Functional Foods: Integrating Traditional Knowledge with Contemporary Nutritional Science

Area of Science:

• Nutritional Science
• Food Science
• Biochemistry

Background:

• Ancient grains (wild rice, millet, fonio, teff, quinoa, amaranth, sorghum) are regaining importance in modern diets.
• They possess dense nutritional profiles and bioactive compounds with health benefits.

Purpose of the Study:

• To synthesize information on ancient grains' nutrients, phytochemicals, and functional properties.
• To emphasize their role in preventing and managing chronic diseases.
• To explore their application in functional foods and dietary strategies.

Main Methods:

• Comprehensive literature review.
• Synthesis of nutritional composition data.
• Analysis of molecular mechanisms of health benefits.

Main Results:

• Ancient grains are rich in protein, fiber, micronutrients, phenolic acids, flavonoids, carotenoids, phytosterols, and betalains.
• These components confer antioxidant, anti-inflammatory, antidiabetic, cardioprotective, and immunomodulatory effects.
• Mechanisms include reduced oxidative stress, modulated inflammation, improved glucose/lipid metabolism, and enhanced gut microbiota.

Conclusions:

• Ancient grains offer significant potential for preventing and managing chronic diseases like cardiovascular disease, type 2 diabetes, and obesity.
• Challenges to wider adoption include technological, agronomic, and consumer factors.
• Future research should focus on clinical trials, data standardization, processing innovations, and sustainable cultivation.
