It also provides significant amounts of folate (Vitamin B9) and Vitamin C, though levels vary slightly between varieties like Romaine or Iceberg. Regarding minerals, Alface contains potassium, which helps regulate blood pressure, and manganese, an essential cofactor for several enzymes involved in metabolism and antioxidant defense. The fiber content, while modest in absolute terms, is highly effective for promoting digestive regularity when consumed as part of a high-volume salad.

Preparation variations

The nutritional profile of Alface remains most stable when consumed raw, which is the standard method of preparation.

Cold-pressing or juicing Alface removes most of the dietary fiber while retaining most vitamins and minerals, though it may lead to a faster glycemic response compared to eating the whole leaf.
