Lettuce is rich in antioxidants, folates, and Vitamins A and K.
Lettuce (Lactuca sativa) (Spanish: lechuga) is a popular leafy vegetable in the daisy family. It ranges in color from yellow to dark green, and some varieties have reddish hues. Lettuce is a major ingredient in salads, and it is a healthy addition to wraps, soups, and sandwiches. Romaine and iceberg are the most common types in western cuisine, but there are many more varieties with unique flavors and nutritional properties. Most types of lettuce are rich in Vitamin K, folates, and antioxidants.
Crisphead lettuce, widely known as iceberg lettuce, is light, crunchy, and full of nutrients like folate and vitamin K.
Romaine’s long, crisp leaves are popular for Caesar salads. It’s high in folate, potassium, antioxidants, and vitamins A and K.
Butterhead lettuce has soft leaves and looks similar to cabbage. It’s particularly high in iron and vitamins A and K.
Leaf lettuce has crisp, ruffled leaves. Both green and red types are high in folate, manganese, and vitamins A and K. Red leaf lettuce is higher in antioxidants.
What does folate do? Vitamin B9 (Folate) is essential for producing red and white blood cells in bone marrow and transforming carbohydrates into energy. Folate is especially important during periods of rapid growth, such as pregnancy, infancy, and adolescence. It’s best to get folate from whole foods.
How much do I need? The recommended daily intake (RDI) of folate varies with age and gestation or lactation:
Are supplements recommended? For most individuals, a balanced diet rich in folate-rich foods such as leafy green vegetables, fruits, nuts, beans, and fortified grains can provide sufficient folate. However, certain individuals may benefit from supplementation. A folate deficiency can lead to lack of energy, poor immune function and impaired digestion. Folate is especially important nutrient for pregnant women to prevent birth defects like spina bifida. It is important to consult a health care professional if you are considering folate supplements. Folic acid, often confused with folate, is a synthetic form of vitamin B9 used in supplements and added to processed food products, such as flour and breakfast cereals. Several studies indicate that chronically elevated levels of unmetabolized folic acid may have adverse health effects. High levels of unmetabolized folic acid have been associated with increased cancer risk. Among elderly people, high folic acid levels can mask vitamin B12 deficiency which, if untreated, may increase the risk of dementia and impaired nerve function.
What are some good plant food sources of folate? Asparagus, avocado, banana, beans, beets, broccoli, Brussels sprouts, citrus fruits, lentils, lettuce, nuts and seeds, papaya, peas, spinach, and wheat germ.
Beets are low in calories and a source of many nutrients, including fiber, folate and vitamin C and contain nitrates and pigments that help lower blood pressure and improve athletic performance.
Papaya is rich in Vitamins A, C, and B9, as well as potassium, the antioxidant lycopene and the papain enzyme. Unripe papaya can stimulate contractions in pregnancy, so it should always be ripened or cooked before eating if you’re pregnant.
Spinach (español: espinacas) is a leafy green flowering plant whose leaves are consumed cooked or raw. Spinach is a good source of VITAMIN C, IRON, POTASSIUM, VITAMIN E, and MAGNESIUM. The possible health benefits of consuming spinach include blood glucose control, lower risk of cancer, and improved bone health. As part of a nutritious diet, it can help support immune function,…
