Health Benefits
Weight Management

Digestive Health

Potential Risks
Compared to Other Greens
One of the main criticisms of iceberg lettuce is its lower nutrient density compared to other leafy greens like spinach, kale, or romaine lettuce. While iceberg lettuce does contain essential nutrients, the amounts are smaller compared to these other options.
Allergic Reactions
Although rare, some people can have an allergic reaction to iceberg lettuce. Symptoms may include itching, swelling, and difficulty breathing.
Foodborne Illness
As with any raw produce, iceberg lettuce may be at risk for foodborne illness, such as E. coli or salmonella. It is important to wash all lettuce thoroughly before eating and store it properly to reduce this risk.
Pesticide Residue
Non-organic iceberg lettuce may contain pesticide residues. Cleaning can remove some, but not all, of these residues. If you’re concerned about this, consider buying organic iceberg lettuce or growing your own.
