Concept explainers
Which is the better choice—to eat processed foods that have been enhanced with phytochemicals or to eat natural foods that are rich in phytochemicals?
To determine: The better choice among, “to eat processed foods that have been enhanced with phytochemicals” or “to eat natural foods that are rich in phytochemicals”.
Concept introduction: Phytochemicals are naturally occurring plant chemicals that are produced either through primary or secondary metabolism. In foods, phytochemicals impart colors, aromas, tastes, and other characteristics. Several phytochemicals have biological activity in the body. Some examples for phytochemicals include carotenoids, flavonoids, terpenes, and so on.
Explanation of Solution
Eating natural foods that are rich in phytochemicals will help as follows:
- Avert DNA damage and promote DNA repair.
- Immune system stimulation for eliciting proper and quick immune response against invading pathogen.
- Hormone regulation.
- Phytochemicals helps to release toxic substances and potential carcinogens from the body.
- Prevent inflammations and oxidative damage that leads to cancerous cells.
- Altering the growth rate of cancerous cells.
- Regulate the damaged cells to induce apoptosis.
