How to Eat Lettuce More Safely in Winter
Doctors don’t say you must completely avoid lettuce — but they strongly recommend caution:
✔ Wash lettuce thoroughly with clean running water
✔ Avoid pre-cut or packaged salads
✔ Store lettuce properly and consume it quickly
✔ Consider lightly cooking leafy greens instead
✔ Replace lettuce with winter-friendly vegetables like spinach, carrots, cabbage, or broccoli
The Bottom Line
Lettuce is not inherently dangerous — but in winter, how and how often you eat it matters. Doctors urge people to be mindful, especially when consuming raw vegetables during colder months.
A balanced, seasonal diet remains the safest choice for maintaining good health year-round.
