Health Benefits of Lettuce
For thousands of years, this leaf has been cultivated as more than a vegetable. It possesses a number of amazing health benefits, they include the following.
Lettuce possesses anti-extracts have shown significant controlling power over inflammation induced by biocatalysts like lipoxygenase and carrageenan. More research is needed in this arena to bolster these results.properties that help in controlling inflammation. In experimental models, lettuce
Lowers Cholesterol Levels
Lettuce can be beneficial in lowering high heart attack and stroke. A study was conducted on rodents to test the impact of lettuce consumption on fat and cholesterol. The results indicated a significant reduction of cholesterol levels as compared to mice that weren’t fed lettuce. Lipid peroxidation was observed in most cases, which was concluded to be responsible for this form of cholesterol control. These results suggest that lettuce could be contributory as a method to reduce the risk factors of CVD.levels that often lead to diseases (CVD) and other dangerous conditions.

One of the major traditional uses of lettuce in Unani medicine was as a sleep inducer. Research into the extracts of lettuce resulted in the isolation of a depressant chemical. This chemical, when administered in experimental animals, showed significant sedative effects. A 2013 research report, suggests that the main component(s) responsible for this effect in lettuce is most likely to be the non-polar agent(s), which are found in the n-butanol fraction (NBF)of this plant. Decreased heart rate and ventricular contractions were also observed. This particular chemical acts by blocking the excitatory signal processes of muscular and neural tissues. The effects of lettuce on sleep are compared to those of diazepam.
Published in the journal Ancient Science of Life Journal, one study stated that lettuce possesses antioxidants with significant free radical-scavenging capabilities. Antioxidants are a wide range of biochemicals mostly found in our diet. They are also very necessary for human health and disease prevention.
Antioxidants act as barriers to free radicals, which are produced during cellular metabolism. These free radicals can attack healthy tissues, cells, and DNA inside them. They can often cause healthy cells to mutate into cancer cells. Antioxidants, on the other hand, counteract these free radicals and neutralize them before the free radical attacks take place.
The latex of lettuce possesses properties. When coming into contact with latex from lettuce, research has shown that Candida albicans and a number of other yeasts were completely deformed. Biochemicals that are considered to possess these antimicrobial properties are the terpenes and cardenolides, as well as enzymes like glucanases. Studies such as these have positive implications for the antimicrobial abilities of this vegetable.
Helps Relieve Anxiety
The been suggested during ancient times and the Middle Ages in medical treaties, such as the Unani system. A 2012 research paper published in the Asian Pacific Journal of Tropical Disease has led to the conclusion that lettuce possesses (anti-anxiety) properties.

As per NIH, leafy greens such as lettuce are also positively associated with our cognitive health.properties of lettuce, as mentioned earlier, have long
Lettuce leaf extracts may help prevent certain types of cancer. According to research published in the Oncology Reports, the water extract of the lettuce (Lactuca sativa), and not the ethyl acetate extract, inhibited the growth of leukemia cells and breast cancer cells. This emphasizes that lettuce has anti-cancer potential. The experiments also suggested that the weight ratio of human lettuce consumption required to kill 50 percent of leukemia cells would be 3 kg (over six pounds).

Food allergies are the abnormal response of the immune system to certain types of food that the body recognizes as harmful. Food allergies that result in are the worst kind and according to the Center for Disease Control, they are on the rise. People who already suffer from food allergies are generally at risk when trying new foods. So, a word of caution is advised while eating lettuce for the first time.
