6 Surprising Benefits of Lettuce

Lettuce Benefits For Health

The health benefits of lettuce include lower cholesterol levels, prevention of cancer, protection of neurons, regular sleep, anxiety control, lower inflammation, and a constant supply of antioxidants.

What is Lettuce?

Lettuce, scientifically known as Lactuca sativa, was first cultivated by the Egyptians thousands of years ago. The Egyptians used the seeds to produce oil and also utilized the leaves of this useful vegetable. The plant also had cultural and religious significance in ancient Egypt, as it was considered to be sacred. Later, the Greeks and Romans also cultivated this crop.

It was in the period between the 16th and 18th centuries that different types of lettuce were developed due to the discovery that a particular sub-species could cross-pollinate with other sub-species. During medieval times in Europe, lettuce was considered to possess medicinal qualities, which were mentioned in several medieval texts. One can find instances of the plant being prescribed as a medicine for several diseases in the Unani medicine system as well. It was prescribed for bilious eructation, disturbed blood pressure, loss of appetite, insomnia, and was used as a tonic for the intestines and digestive system, and as a method to stop sexual urges.

The dried latex of lettuce was prescribed for inducing sleep and was used as nasal drops, a sedative, an anti-spasmodic, and anodyne. During the medieval times and into the beginning of modern times, lettuce spread from Europe to North America. During the 19th century, it spread to other parts of the world as well, particularly to Asia, South America, Africa, and Australia. Today, lettuce can be found in almost all parts of the world, from the Americas to Siberia.

Health Benefits of Lettuce

For thousands of years, this leaf has been cultivated as more than a vegetable. It was also thought to possess medicinal properties by ancient people. The health benefits that have been confirmed by modern scientific research include the following.

Controls Anxiety

The neurological properties of lettuce have long been suggested and exploited during ancient times and the Middle Ages in medical treaties such as the Unani system. Detailed research in recent times has led to the conclusion that lettuce possesses anxiolytic properties. When lab animals were given lettuce extracts, their locomotive activity was reduced, suggesting considerable anxiolysis.

Induces Sleep

One of the major traditional uses of lettuce in Unani medicine was its use 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. Decreased heart rate and ventricular contractions were also observed. This particular chemical acts by blocking the excitatory signal processes of muscular and neural tissues.

Protects Neuronal Cells

Neurons are brain cells that form physical connections to make up memory. The death of neurons in particular connections or circuits can result in the loss of memory. In some extreme cases, significant neuronal death can result in the onset of diseases like Alzheimer’s. The extracts from lettuce showed considerable control of neuron cell death due to its role in glucose/serum deprivation (GSD). The research has also mentioned that lettuce has the potential to be used in neuroprotection as a common remedy for neurodegenerative diseases.

Anti-inflammatory Agent

Lettuce possesses anti-inflammatory properties that help in controlling inflammation. In experimental models, lettuce extracts have shown significant controlling power over inflammation induced by biocatalysts like lipoxygenase and carrageenan.

Lowers Cholesterol Levels

Lettuce can be beneficial in lowering cholesterol levels that often lead to cardiovascular diseases and other dangerous conditions. High LDL (bad) cholesterol levels are harmful and can cause heart attack and stroke. A study was conducted on mice to test the impact of lettuce consumption on fat and cholesterol. The results indicated a significant reduction of cholesterol levels 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.

Antimicrobial Agent

The latex of lettuce possesses antimicrobial properties. Candida albicans and a number of other yeasts were completely deformed upon coming into contact with the latex from lettuce. Biochemicals that are considered to possess these antimicrobial properties are the terpenes and cardenolides, as well as enzymes like glucanases.
