Pflanzenstoffe

Pflanzenstoffe, also known as phytochemicals, are chemical compounds produced by plants. These substances are not essential for plant survival, but they often play protective roles, such as deterring herbivores or defending against pathogens. Humans consume Pflanzenstoffe through their diet, primarily from fruits, vegetables, grains, and legumes.

While not considered nutrients in the same way as vitamins or minerals, Pflanzenstoffe are of significant interest due to their potential health benefits. Many of these compounds exhibit antioxidant properties, helping to neutralize harmful free radicals in the body that can contribute to chronic diseases. Others may possess anti-inflammatory, antimicrobial, or even anti-cancer effects.

The diversity of Pflanzenstoffe is vast, with thousands of different compounds identified. They are often classified into several major groups, including polyphenols (such as flavonoids and phenolic acids), terpenoids, alkaloids, and organosulfur compounds. Each group contains numerous individual substances with unique chemical structures and biological activities.

For example, flavonoids are found in berries, tea, and chocolate, and are studied for their cardiovascular benefits. Carotenoids, like beta-carotene in carrots and lycopene in tomatoes, are known for their antioxidant and vision-supporting roles. The specific health effects of individual Pflanzenstoffe are a subject of ongoing scientific research. Dietary intake of a wide variety of plant-based foods is generally recommended to ensure exposure to a broad spectrum of these beneficial compounds.
