1. Higher Risk of Bacterial Contamination
In winter, lettuce is often:
Grown in greenhouses
Imported from distant regions
Stored for long periods in cold environments
This increases the risk of contamination with harmful bacteria such as E. coli, Listeria, and Salmonella, which can survive and even thrive at low temperatures.
Doctors warn that foodborne infections are more dangerous in winter, as the body’s immune response is often weaker.
2. Harder to Digest in Cold Weather
Traditional medicine and modern nutrition both agree that the digestive system works more slowly in cold conditions. Lettuce is:
High in water
Difficult to digest when eaten raw
Cooling to the body
In winter, this can lead to:
Bloating
Abdominal discomfort
Diarrhea
Worsened digestive disorders
3. Weaker Immune System Effects
Winter is already a season when:
Vitamin D levels drop
