As a result, lettuce is now a component of all green salads. These nutrients play essential roles in our bodies and contribute to overall health improvement.⁹

Other health benefits of lettuce

Removes toxins

Chemical reactions resulting from metabolism in our body produce toxins such as free radicals, urea, etc. These toxic substances are harmful to our bodies and must be removed.

Minerals in the lettuce also assist in removing the toxic substances from our bodies and regulate acid-base balance.

Antioxidant

Lettuce, rich in vitamin C, possesses antioxidant properties and prevents us from the harmful effects of free radicals.¹⁰ It also prevents atheroma formation and helps in improving heart health. 

Vitamin C also lowers blood pressure and reduces the risk of coronary artery disease and dementia, and also improves iron absorption.

Brain development

Pyridoxine, commonly known as vitamin B-6, is crucial for healthy immunological and neural systems and optimal brain development.

Lettuce can prevent neuronal cell death and cognitive decline, which can lead to Alzheimer's disease and other neurological disorders. By consuming lettuce, individuals can help to protect their cognitive health by promoting endothelial function and reducing the risk of neurological disorders.

Anxiolytic

Lettuce also possesses some anxiolytic properties and can help alleviate anxiety.³ It also aids in managing mental health disorders. 

Clotting

Vitamin K in lettuce is vital for the synthesis of clotting proteins.

Anti-microbial

Due to its antimicrobial characteristics, lettuce aids in the battle against pathogenic microbes that can result in several ailments. This is because terpenes and cardenolides are present, which serve to protect our bodies from harmful germs.⁴ Lettuce also boosts immunity and helps our body in fighting microbes.

Anti-inflammatory

The seed methanol/ether (70/30) extract of Lactuca sativa (lettuce) has anti-inflammatory properties.^{5 6} This is why lettuce is also commonly used as a herbal medicine to treat inflammation and relieve pain.

Boosts immunity

Research has shown that polysaccharides extracted from stem lettuce have been shown to have some immunomodulatory properties and thus can boost our immune system. They are used as immunomodulatory agents in the pharmaceutical and functional food industries.⁷

Bone health

Lettuce also helps in improving bone health. Vitamin A plays a crucial role in developing new cells, and vitamin K is essential for laying down collagen meshwork. Collagen provides strength to the tissue and is vital to keep it intact. Vitamin C in lettuce prevents bone depletion and is essential for women at risk of osteoporosis.⁷

Anti-cancer

Due to the presence of some phytochemicals, such as -carotene, ascorbic acid, and chlorophyll, lettuce has been demonstrated to have possible cancer-preventive qualities. These substances may lower the risk of colorectal, lung, and liver cancer and limit the formation of several tumours, including those related to the breast, liver, skin, pancreas, prostate, and stomach.⁷

Regulates sugar levels

Lettuce leaves contain bioactive substances like lutein, lactucaxanthin, and beta-carotene that may have anti-diabetic properties. The enzymes,amylase and glucosidase, which are involved in the breakdown of starch during digestion, are inhibited by Lactuca xanthin, which may help lessen post-meal hyperglycemia.⁷

Hepatoprotective

It has been demonstrated that lettuce extracts have hepatoprotective properties and may be helpful in preventing liver damage brought on by paracetamol. Additionally, lettuce extracts may be used as a therapeutic agent to treat human diseases brought on by free radical damage.⁷

Nutritional facts

Losing weight while keeping the maximum nutrient content in a meal is a big challenge. Lettuce plays a huge role and has almost become a part of all salad recipes.

Lettuce is about 95% water, contains zero fat and cholesterol and is rich in minerals such as calcium, iron, magnesium, potassium, copper and zinc. It also contains essential vitamins such as vitamin A, B1, B6, niacin, vitamin C, vitamin D and vitamin K. It also contains riboflavin and folic acid.²

Trans fat is bad for your health, increasing your cholesterol levels and causing different vascular disorders such as stroke and heart attack. Being a poor source of trans fat, lettuce can be consumed in high quantities without any harm.

The only downside is that lettuce is not a good source of protein as it contains less than 1g of protein per 100g of lettuce.²

Side effects and other concerns

Lettuce was first cultivated by Egyptians around 2000 years ago. It has been widely consumed since then as herbal medicine and a part of regular meals. There are no specific allergens in it, and it is, therefore, safe for everyone. However, keeping some potential side effects in mind while taking lettuce is crucial.

Vitamin K and warfarin

Excess of everything is bad. Consuming a large amount of lettuce can also be flawed in some cases. Vitamin K plays an essential role in clotting. However, suppose a patient is on a blood thinner like warfarin. In that case, vitamin K must not be taken in high quantities, as research has shown that vitamin K can make warfarin less effective.⁸ Hence, always consult your doctor before consuming large amounts of vitamin K in any form while you are on blood thinners.

Anti-nutrients

Similarly, Several anti-nutrients, including nitrates and alkaloids, present in lettuce may be harmful if consumed in large amounts. Nitrates can cause infantile methemoglobinemia, carcinogenesis, and teratogenesis.

In contrast, tropane alkaloids, in particular, can have severe effects such as fast heartbeat, paralysis, and death. In large doses, tryptamine alkaloids can also be toxic.

Summary

Lettuce is both nutritious and satisfying. When incorporated into a balanced diet, it can add variety to your diet and help you lose weight. It has beneficial effects on our bodies and improves overall health and ensures that you are getting the nutrients you need to stay healthy.
