The interface between plant metabolic engineering and human health

Area of Science:

• Nutritional Science
• Plant Biotechnology
• Preventive Medicine

Background:

• Phytonutrients in fruits and vegetables offer significant health benefits for chronic disease prevention.
• Current data strongly support the role of phytonutrients in ameliorating chronic diseases.

Purpose of the Study:

• To highlight the need for fundamental research to define phytonutrients and their health impacts.
• To establish goals for biofortifying crops with phytonutrients.
• To explore the potential of metabolic engineering and genetic engineering in enhancing dietary phytonutrient levels.

Main Methods:

• Review of existing data on phytonutrient benefits.
• Identification of research gaps in understanding physiological effects, mechanisms, food matrix impact, and interactions.
• Discussion of metabolic engineering and genetic engineering strategies for crop biofortification.

Main Results:

• Persuasive evidence exists for phytonutrient benefits in chronic disease prevention.
• Fundamental research is crucial to define phytonutrients, their actions, and interactions.
• Genetic engineering offers a viable strategy to increase dietary phytonutrients.

Conclusions:

• Reliable dietary recommendations and preventive medicine campaigns require deeper understanding of phytonutrients.
• Biofortification of crops, particularly through genetic engineering, can significantly enhance phytonutrient intake.
• Increased phytonutrient consumption can mitigate chronic disease risk, even with declining overall diet quality.
