Anticancer Properties of Foods: Key Bioactive Compounds and Mechanisms
Phytochemicals in Vegetables: Broccoli and Brassica Genus
Broccoli and other vegetables from the brassica genus are rich in phytochemicals like glucosinolates and phenolic compounds, which have strong antioxidant effects and can modulate molecules involved in cell cycle regulation and apoptosis. Sulforaphane, a key compound in broccoli, is especially noted for its chemopreventive properties, with evidence supporting its role in lowering cancer susceptibility and aiding in both prevention and treatment across various cancer types Gasmi2023Vivanco2023.
Organosulfur Compounds in Garlic and Allium Vegetables
Garlic and related Allium vegetables contain sulfur-based compounds such as allicin, diallyl sulfide, and S-allylcysteine. These compounds have demonstrated anticancer effects by altering mitochondrial function, inhibiting angiogenesis, promoting apoptosis, and regulating cell proliferation. These effects have been observed in multiple cancer types, and regular consumption of garlic is advocated for its potential to reduce cancer risk De Greef2020Chaurasia2025.
Flavonoids and Polyphenols in Fruits, Vegetables, and Beverages
Flavonoids, found in fruits, vegetables, green tea, wine, and cocoa, are polyphenolic compounds with diverse anticancer actions. They can act as antioxidants, induce apoptosis, arrest the cell cycle, and suppress cancer cell proliferation and invasiveness. Flavonoids also modulate reactive oxygen species and downregulate pro-inflammatory pathways, contributing to their anticancer potential .
Protein Hydrolysates and Peptides from Food Sources
Bioactive peptides and protein hydrolysates derived from foods such as milk, eggs, fish, soybeans, and legumes have shown immunomodulatory and anticancer activities. Their effects are linked to their amino acid composition and sequence, and they have demonstrated antitumor and antiproliferative properties in cell and animal models, primarily through antioxidative mechanisms Nwachukwu2019Chalamaiah2018.
Lignans and Bioactive Compounds in Sesame
Sesame seeds contain lignans like sesamin and sesamol, which have been studied for their anticancer, anti-inflammatory, and antioxidant properties. These compounds target chronic diseases and malignancies, supporting the use of sesame as a functional food with potential anticancer benefits .
Mung Bean and Other Functional Foods
Mung beans are highlighted for their anti-inflammatory, antioxidant, antiproliferative, and immunomodulatory properties, which may help prevent carcinogenesis and metastasis. Their bioactive phytochemicals and proteins contribute to their emerging role as a functional food with anticancer potential .
Dietary Patterns: The Southern European Atlantic Diet
The Southern European Atlantic Diet (SEAD), which includes foods rich in beneficial biomolecules such as olive oil, paprika, and brassica vegetables, is associated with a lower risk of cancer. The diet’s chemical composition and the presence of bioactive compounds are believed to contribute to its anticancer properties, though further research is needed to fully understand its benefits .
Clinical and Translational Perspectives
Epidemiological and nutritional studies consistently link the consumption of botanical foods with reduced cancer risk and improved prognosis. However, translating promising preclinical findings into clinical success remains challenging due to the complexity of botanical products and the need for well-designed studies. Mechanism-driven and clinically focused research is essential for developing botanical foods as multitarget anticancer agents .
Conclusion
A wide range of foods—including broccoli, garlic, sesame, mung beans, and those featured in the Southern European Atlantic Diet—contain bioactive compounds with demonstrated anticancer properties. These compounds act through antioxidant, anti-inflammatory, immunomodulatory, and direct anticancer mechanisms. While evidence from laboratory and animal studies is strong, further clinical research is needed to confirm these benefits and optimize dietary recommendations for cancer prevention and therapy Gasmi2023Nwachukwu2019Vivanco2023+7 MORE.
