What is the Origin of Dietary Phytonutrients?

The term is a combination of the Greek word phyto, meaning plant, and "nutrient," indicating their source and biological utility. This area of study grew significantly with the recognition that the protective effects of plant-rich diets, like the Mediterranean diet, were often attributed to these secondary metabolites. Modern clinical nutrition increasingly focuses on the therapeutic potential of specific phytonutrient classes.

What is the Mechanism of Dietary Phytonutrients?

The mechanism of action is diverse, but a key function involves antioxidant activity, neutralizing reactive oxygen species that contribute to cellular aging and dysfunction. Many phytonutrients also act as selective enzyme modulators, for example, influencing the activity of aromatase or phase I and II detoxification enzymes in the liver, which are critical for the healthy clearance of spent hormones like estrogen. This modulation helps maintain hormonal homeostasis and cellular integrity.

Dietary Phytonutrients

Meaning

Dietary phytonutrients are biologically active, non-essential compounds naturally produced by plants, such as polyphenols, flavonoids, and carotenoids, which confer health benefits beyond basic nutrition. These compounds function as signaling molecules within the human body, influencing cellular pathways and gene expression. From a hormonal perspective, phytonutrients are crucial for modulating estrogen metabolism, reducing chronic inflammation, and supporting detoxification processes in the liver.
