With over 2,000 varieties of lettuce available, choosing the healthiest option isn’t always straightforward. While iceberg and sucrine lettuce might look crisp and appealing, nutrition experts warn they’re far from the most beneficial choice if you want to maximize your vitamin and antioxidant intake.
The problem with compact-headed lettuces
According to nutrition specialist Nathalie Majcher, varieties with tightly packed leaves — like iceberg and sucrine — don’t allow enough sunlight to penetrate their inner layers. This lack of light limits the production of health-promoting nutrients and antioxidants in the leaves. In other words, while these lettuces may offer crunch, they deliver less nutritional value compared to more open-leaf varieties.
What to eat instead
The key to a nutrient-packed salad lies in its color and leaf structure. Darker, more open lettuces — such as romaine, curly lettuce, batavia, escarole, or radicchio (trévise) — tend to be richer in vitamin K, vitamin B9 (folate), beta-carotene, and polyphenols. The deeper the color, the higher the concentration of antioxidants that help protect cells from oxidative stress and support overall health.
A simple swap for better nutrition
Next time you’re at the market, resist the temptation to grab the palest head of lettuce on the shelf. Instead, reach for those with darker, looser leaves — your body will thank you for the extra vitamins, minerals, and antioxidants. By making this small change, you can transform a simple salad into a nutrient powerhouse without sacrificing flavor or freshness.
