Doctors Warn: Bitter Vegetables May Contain Natural Toxins

Cucurbitacins are among those defensive compounds. In normal commercial vegetables, these substances are present at extremely low levels or are bred out entirely. However, unusual growing conditions, accidental cross-pollination, environmental stress, or genetic variations can occasionally lead to elevated concentrations.

When levels become unusually high, the vegetable may develop a distinctly bitter flavor that is impossible to miss.

Symptoms associated with consuming large amounts of cucurbitacins may include:

• Nausea
• Vomiting
• Diarrhea
• Abdominal pain
• Digestive discomfort

In severe cases, medical attention may be necessary.
