Phenolic acids, a class of plant-derived phytochemicals that includes compounds such as caffeic acid, ferulic acid, and gallic acid, have attracted scientific interest for their potential role in cancer prevention. These compounds are abundant in fruits, vegetables, whole grains, and certain beverages like coffee and tea. Laboratory and animal studies have demonstrated that phenolic acids possess antioxidant, anti-inflammatory, and anti-proliferative properties, which may contribute to the inhibition of cancer initiation and progression. Specifically, they can scavenge free radicals, modulate signaling pathways involved in cell growth and apoptosis, and inhibit the activity of enzymes associated with tumor promotion. Epidemiological studies have suggested a correlation between diets high in phenolic-rich foods and reduced cancer risk, particularly for colorectal and breast cancers. However, it is important to note that most of the available evidence is preclinical or observational. Direct clinical trials assessing phenolic acids as isolated supplements for cancer prevention in humans are limited and often inconclusive. The observed benefits in human populations are generally associated with the consumption of whole foods rather than purified phenolic acids. As such, while there is a scientific rationale and some supporting evidence, it is not yet strong or definitive enough to recommend phenolic acids as a standalone preventive or therapeutic agent for cancer. Health authorities continue to recommend a diet rich in fruits and vegetables, partly due to their phenolic content, as part of a cancer-preventive lifestyle.
