36 free lettuce kitchen insights and benefits

Did you know that ancient Greeks believed that eating lettuce would make you sleepy?

• Indeed, lettuce has remarkable calming effects on the body. Since this is the case, eating an excessive quantity of lettuce will cause you to get drowsy very quickly. It is generally known that the presence of a component called lactucarium, which is a milky fluid, is recognised for its relaxing and analgesic properties, which may assist in the induction of sleep.
• The sunflower family includes a number of green vegetables, one of which being lettuce. Although it is said to have originated in the Mediterranean area, it may now be found all over the globe. The cultivation of lettuce requires a cooler temperature, which delays the appearance of the plant’s blooms and promotes the healthy growth of its leaves.
• The following are the four types of lettuce that are cultivated commercially:
  1. Celtuce, sometimes known as asparagus lettuce, is a kind of lettuce that has elongated leaves and a succulent, edible stem.
  2. A head of romaine or cabbage lettuce, in which the leaves are arranged in a compact head
  3. Leaf or curled lettuce, which consists of a rosette of leaves that are curled, finely cut, smooth-edged, or oak-leaved in form.
  4. Cos or romaine lettuce, both of which have leaves that are completely smooth and create an elongated, tall head.
• The preservation procedure that was utilised at the beginning of the 20th century in California gave rise to the name “Iceberg,” which was given to the brand. Because there were no freezers accessible at the time, vast amounts of ice had to be used to keep lettuce from going bad while it was being transported on trains to various markets. Because the icebergs were loaded into the carriages and floated on top of the lettuce as they travelled to their ultimate destinations, the lettuce became known as iceberg lettuce.

Lettuce nutrition values and health benefits

1. It is true that lettuce leaves provide a lot of calories for a green food. The calorie count of 100 g of fresh greens is 15 cal. Nonetheless, they are a treasure mine of phytonutrients, many of which have health-promoting and disease-preventive characteristics.
2. A lot of vitamins may be found in lettuce. In addition to various vitamins A and beta-carotene, its fresh leaves are a rich source of lutein. With only 100 g, fresh, raw lettuce provides 247% of the daily value for vitamin A and 4,443 mg for beta-carotene. Antioxidant properties are well-documented for these substances. Maintaining normal mucosal and cutaneous health, as well as good vision, requires enough intake of vitamin A. Naturally occurring flavonoids in fruits and vegetables aid in protecting the body from developing lung and oral cancers.
3. There is a high concentration of vitamin K in it. Vitamin K may have an effect on bone metabolism. It raises osteoblastic activity in bone cells, which is thought to increase bone mass. It has also been demonstrated to have a significant role in the treatment of Alzheimer’s disease by lowering neuronal damage in the brain.
4. Folate and vitamin C are both abundant in fresh leaves. Folates serve a crucial role in preventing neural tube defects in the developing foetus by serving as co-factors in the enzyme metabolism required for DNA synthesis.
5. Vitamin C is a powerful natural antioxidant, therefore getting enough of vitamin C via diet may help you fight off infections and reduce inflammation. Anti-inflammatory and immune system support both depend on vitamin C’s ability to mop up free radicals.
6. Zeaxanthin, found in high concentration in lettuce (1730 mg per 100 g), is an important dietary carotenoid thought to work as an antioxidant and to filter UV radiation that is detrimental to the retina. Recent studies have shown that older adults who consume diets rich in xanthine and carotenes are less likely to develop ARMD.
7. Essential minerals for metabolic activity are present in sufficient quantities. Potassium serves an important function in controlling heart rate and blood pressure, making it a key component of cell and body fluids. The antioxidant enzyme superoxide dismutase requires manganese as a co-factor to function properly and protect cells from free radical damage. Copper plays a key role in the production of red blood cells. In order to make RBCs (red blood cells), iron is essential.
8. Thiamine, pyridoxine, riboflavin, and niacin are only few of the B-complex vitamins found in abundance.
9. The vast majority of individuals are able to consume lettuce without risk. It is not a typical allergy at all. Consuming an excessive amount of lettuce is not particularly problematic due to the fact that it has a low calorie count. In contrast, there have been a significant number of reports of E. coli being found in lettuce during the last several years. There are occasions when lettuce, particularly romaine, is recalled.

100g of lettuce has 15 calories (62kj), 1.4g protein, 0.2g fat, and 2.9g carbs, including 1.3g fibre.

How to store lettuce and how to buy them

• The shelf life of head lettuce varieties such as iceberg or romaine is between one and three weeks, but the shelf life of loose leaf varieties such as butterhead or green leaf lettuce is approximately seven to ten days. Keep your lettuce well-wrapped and stored in the refrigerator; however, be sure to give it some ventilation so that it may release any extra moisture.
• Because the leaves are packed so closely together in crisp head lettuce, it has a longer shelf life than leaf lettuce does because the leaves on the outside protect the ones on the inside. Therefore, if that head of lettuce is kept in storage for an extended length of time, the damage that occurs is often limited to the outside leaves, while the inside leaves remain mostly unaffected.
• Your lettuce will remain fresh at room temperature for about 2 to 4 days, depending on whether or not it is a head or loose-leaf variety. However, depending on the kind, you may preserve it for anywhere from seven to twenty-one days if you store it in the refrigerator.
• The key to maintaining the lettuce’s freshness for as long as possible is proper humidity control. For its crisp texture, lettuce needs a certain amount of moisture, but it can not have too much of it or it would wilt and become sticky. It is a delicate balancing act. Allowing airflow into the space where the plant is growing is the simplest and most hands-off technique to regulate the level of humidity. This should be done in such a manner that the plant is able to expel any surplus water without becoming too dry.
• Next, keep in mind that lettuce has to be kept apart from other fruits and vegetables that produce ethylene, such as apples, pears, peaches, or tomatoes. The rusty red and brown marks that may be seen on the leaves are caused by an excessive amount of ethylene.
• The best approach to store lettuce leaves is to put them in a freezer bag and add a paper towel below and above them to help reduce the amount of moisture that is retained in the leaves. This will keep the lettuce leaves fresh for a longer period of time. You may let some ventilation inside the bag by leaving the top of it just partially open. With that configuration, you should be able to save data for the seven days I specified previously.
• Lettuce, like many other green vegetables, does not retain its freshness for an extended period of time. As time passes, lettuce begins to lose its crispness and wilt. Its formerly solid structure melts away, and it becomes more pliable. Following this, the lettuce will take on a brown colour. You still have a little bit of time left to utilise the lettuce before it begins to go bad.
  1. When working with heads of lettuce, remove any outside leaves that are discoloured or wilted looking. Make sure the interior leaves are checked. If things seem to be in excellent condition, you are free to make use of them.
  2. You may use the same procedure with loose-leaf lettuce if the mushy leaf is isolated to only one or two leaves. On the other hand, if the damaged pieces are extensive, it is best to dispose of them.
  3. As the deterioration moves farther away, the leaves will start to smell weird, like they have rotted, or like they have too much water. If such is the case, you must under no circumstances utilise the leaves.
  4. If the lettuce in the bag has not been opened and the bag seems bulging, this is an indication that germs have gained control of the lettuce. Because the bacteria colony produces gas, and because the plastic bag is still sealed, the gas is unable to escape, causing the bag to get inflated.

Cooking techniques, secrets, and tips from the kitchen

1. We all know that lettuce is the basis for most salads, but let us be honest: lettuce has so much more to give than just that! I like the fact that a single head of lettuce may be used in a number of ways over the period of many days, preventing the monotony of eating the same thing every day. Lettuce may be the star of the show in lettuce wraps or salads, or it can perform a comedic cameo by being shredded and sprinkled on top. You can make lettuce last all day by juicing it in the morning and snacking on it in the afternoon.
2. Create a one-of-a-kind flavour profile by blending bold, spicy, and subtle flavours.
   • If you are serving a salty cheese or olives, pair them with something sweet like apples, roasted peppers, or ripe tomatoes.
   • To neutralise bitter tastes, use something sharp and acidic.
   • Crunchy roasted almonds, seeds, or croutons are just a few examples of how you may use texture-enhancing items to elevate your cuisine.
   • Adding cooked and cooled pulses and grains like puy lentils, spelt, farro, and chickpeas to a meal may give it texture and substance while also adding a little of bite.
   • Your salad will have more bite if you include raw broad beans, asparagus, and peas during the beginning of the growing season.
   • Finally, spend some time layering and arranging your parts so that their various colours, shapes, and contrasts stand out.
   • A dish’s final presentation is enhanced by the addition of fresh herbs, crumbled cheese, nuts, and vibrantly coloured sauces.
   • That is it; now you can build your own version of your favourite salad just way you want it.
3. Shred some lettuce (romaine or iceberg work well) and toss it into your soup until it is nice and crunchy. It may lose some of its crisp crunch as it cooks, but it will provide a welcome surprise of sweetness and texture to the soup as it cooks. Arugula, spinach, and other darker, softer greens are a great alternative to lettuce for adding more vegetables to your diet. Lettuce in soup is a quick and easy method to increase your daily intake of vegetables.
4. It is well knowledge that lettuce has a high water content; take advantage of this by adding it to your next smoothie or beverage. Only a few leaves and your preferred fruits and vegetables are required to produce a delicious drink. Tomatoes, carrots, spinach, lettuce, watercress, parsley, celery, and a beet were among the first eight veggies planned for usage. This homemade version of the traditional drink is delicious, nourishing, and surprisingly flexible.
5. If you want to avoid the carbs in traditional wrappers like lavash or bread but do not want to give up flavour, lettuce wraps are a great solution. While most people associate lettuce wraps with Asian fillings, you may also try them with baked falafel, taco, or fajita filling, or even as a bread replacement when making a burger.
6. Without some lettuce, wraps and spring rolls would be missing something essential. Lettuce may not provide much flavour to wraps and rolls, but it does add crispness, texture, and an attractive hue. I made a quick and easy summertime snack by wrapping a salad in rice paper rolls and serving it chilled. Wrapped in romaine lettuce and drizzled with a creamy miso-tahini vinaigrette, these roasted shrimp, avocado slices, and lettuce leaves make for a light and refreshing summertime meal.
7. A tasty rice or noodle bowl will include a balance of protein, carbs, textures, and flavours. Since it is so little, chopped lettuce is able to absorb a lot of flavour from dressings and sauces, making it a go-to salad ingredient. Make the meal as easy as possible so that you may use a wide range of vegetables. Combine rice noodles, a large handful of fragrant herbs, crunchy bean sprouts, savoury protein, and a salty, acidic, and sweet sauce combine to make a beautifully complex dinner that is deceptively simple to prepare at home. Consider this more of a source of motivation and direction than a strict recipe.
8. Turn lettuce into a sauce by treating it as you would a strong-flavoured herb like basil. To increase the nutritional value of your favourite pesto recipe, try substituting lettuce for half of the basil. If you find that the pesto’s predominant flavour is basil, adding some chopped lettuce might give texture and wetness without overpowering the dish.

History of lettuce from the beginning until today

• Ancient Egyptians grew lettuce to get oil from its seeds. As early as 2680 BC, Egyptians were cultivating the plant for its tasty leaves. Lettuce, a sacred plant of Min, was brought to his festivals and placed near his statues. The plant helped the god “untiringly complete the sexual act.” Its usage in religious ceremonies has inspired countless tomb and wall paintings.
• The cultivated variety, 75 cm (30 in) tall, resembled a huge romaine lettuce. Egyptians created upright lettuces, which the Greeks and Romans later adopted. Columella, a first-century Roman agriculturalist, listed many lettuce varieties, some of which may have been precursors to modern lettuces.
• Medieval literature mentions lettuce as a medicinal herb. Hildegard of Bingen included it in her 1098–1179 medicinal plant writings, and several early herbals described its uses. Joachim Camerarius first described head lettuce, loose-leaf lettuce, and romaine (or cos lettuce) in 1586.
• In the late 15th century, Christopher Columbus brought lettuce from Europe to the Americas, a gastronomic breakthrough. To fulfil farmers’ demands, Europe, particularly Holland, manufactured numerous varieties during the late 16th and early 18th centuries. Modern garden plants are described in mid-18th- and early-19th-century literature.
• Since lettuce has a short shelf life, it was historically sold near the farm. In the early 20th century, improved packing, storage, and shipping technologies increased lettuce’s lifespan, transportability, and availability. Vacuum cooling, which enabled field chilling and packaging of lettuce instead of ice-cooling in packing houses, revolutionised the lettuce business in the 1950s.
• Many seed companies profit from salad lettuce, which is easy to grow. Many manufacturers, especially in the US, change the name of a variety each year, making it harder to trace its origins. This strategy is used to boost sales by promoting a “new” variety or to hide the fact that it was developed by a competing seed company.
• In the late nineteenth century, there were 65 to 140 lettuce varieties, depending on the degree of variety permitted, compared to 1,100 identified lettuce variants. Nations also changed names drastically. Most lettuce is eaten as a vegetable, but its wild relatives produce a leaf that looks more like tobacco.
