Phytochemicals
The potato skins you might be peeling away and discarding are actually packed with protective compounds that could benefit your health—and understanding what threatens potato crops helps explain why your grocery store prices spike after a bad growing season.
Potatoes aren't just starchy comfort food—they're loaded with natural plant chemicals, especially in the skin and in purple or red varieties, that help fight harmful bacteria, reduce inflammation, and may even slow cancer cell growth in lab tests. Scientists also reviewed the bugs, fungi, and viruses that attack potato plants, including a notorious mold that caused the Irish Famine. Together, these findings paint potatoes as both a functional food and a plant with sophisticated natural defenses.
Key Findings
Potato peel and pigmented (colored) tubers show significantly higher radical scavenging capacity than inner flesh, suggesting the skin is the most bioactive part of the potato.
Key compounds—chlorogenic acid, glycoalkaloids (α-solanine and α-chaconine), and anthocyanins—demonstrated antimicrobial and antiproliferative effects against multiple cancer cell lines and microorganisms in lab studies.
Major biotic threats including Phytophthora infestans (late blight), Ralstonia solanacearum (bacterial wilt), Potato virus Y, and nematodes collectively represent the primary drivers of global potato yield loss.

Potatoes contain a surprisingly rich array of plant compounds—especially in their skins and colorful varieties—that show real promise as antioxidants, antimicrobials, and even anticancer agents, while the same plant faces serious threats from pathogens and pests that cut yields worldwide.
