Lotus seed is a quick snack to munch on while watching a movie. Lotus seed is also known as lotus nut or kamal seed. The scientific name of lotus seeds is Nelumbinis semen, derived from the lotus plant, Nelumba nucifera. It has been a functional food, medicine and vegetable for about 7000 years. There are two types of dried lotus seeds, one with white peel and the other with brown peel. Lotus seeds have been extensively produced and cultivated in India, Japan and China. Lotus food has been approved as food and medicine by ‘Ministry of Health of the People’s Republic of China’. Lotus seeds have fewer calories and are a host of nutrients; therefore, they play an essential part in the functions of the body.1 Let us look at some of the health benefits of lotus seeds.
Did you know?
Lotus seeds may contain several bioactive compounds like alkaloids, glycosides, triterpenoids, flavonoids, polyphenols, polysaccharides, essential oils and many more. Below are the nutritional components of Lotus seeds:
Several studies have shown that lotus seed may have the following properties:
Beta-galactosidase, a compound found in lotus seeds, can break the lactose molecule of milk and make it lactose-free. From my experience, the combination of lotus seeds and milk may aid lactose-intolerant people.
Dr. Siddharth Gupta, B.A.M.S, M.D (Ayu)
Some of the potential uses of lotus seed are:
Excess weight in the body is due to adipocytes (fat cells). A study by Achike et al. in 2011 showed that lotus seeds may inhibit the formation of fat cells and reduce the weight of the fat tissues. In addition, polyphenols found in lotus seeds may improve the lipid profile in the body.1 However, further studies are required to check if lotus seeds can help to manage weight. Therefore, you must consult your dietician before making any diet changes.
Alzheimer’s disease is a neurodegenerative disorder which results in memory loss and other mental impairments. Lotus seeds may have neuro-protective effects i.e, it may protect the nerve cells from damage as in the case of Alzheimer’s disease. A study by Kim et al. in 2014 showed that proanthocyanidins in lotus seeds may reduce brain ageing and cognitive impairment. In addition, lotus seeds may reduce the risk of Alzheimer’s disease by decreasing the harmful free radicals and accumulation of unnecessary calcium.1 However, further studies are required to check if lotus seeds can be beneficial in improving the symptoms of Alzheimer’s disease. You must consult your doctor if you suspect any symptoms of Alzheimer’s disease.
A study by Sugimoto et al. in 2008 showed that bioactive compounds like saponins, flavonoids, alkaloids and tannins may help to reduce anxiety and depression. The alkaloids in lotus seeds may increase the time of sleep. Getting good sleep may help manage depression. However, these studies were conducted on mice.1 Further studies on humans are required to check if lotus seeds may be beneficial for anxiety and depression.
A study by Tang et al. in 2017 showed that lotus seeds may have anti-microbial properties. Lotus seeds may disrupt the structure and function of the plasma membrane. Additionally, lotus seeds may inhibit the growth of Salmonella sp., Staphylococcus aureus, Escherichia coli., Klebsiella sp., Shigella, and Pseudomonas sp.1 However, more studies are required to confirm if lotus seeds can be used for microbial infections. You must consult your doctor if you experience any microbial infection.
A study by Mani et al. in 2010 showed that lotus seed might be used in the case of type 1 and type 2 diabetes. Various minerals present in lotus seeds may be beneficial for diabetes. For example, zinc in lotus seeds reduces oxidative stress in type 1 diabetes patients and transports glucose to the cells in type 2 diabetes patients. Chromium may increase the number of insulin receptors and glucose metabolism, thereby decreasing blood glucose levels in type 2 diabetes patients.3 However, further studies are required to check if lotus seeds can help to reduce blood glucose levels. You must check your blood sugar levels regularly and consult your doctor in case of abnormal blood sugar levels.
A study by Poornima et al. in 2013 showed that lotus seeds might act against lung cancer. A bioactive compound, nepherine in lotus seed, may kill the cancer-causing cell (apoptosis) and inhibit their growth.4 However, further studies are required to check if lotus seeds may act against cancer. Therefore, you must consult your doctor if you suspect cancer instead of self-medicating.
A study by Chakravarthi et al. in 2009 showed that the flavonoids in the lotus seeds might help to relieve pain. Lotus seeds may inhibit the cyclooxygenase enzyme, which is responsible for releasing pain mediators.5 However, further studies are required to check if lotus seeds can help relieve pain. Therefore, you must consult your doctor if you experience prolonged pain.
A study by Rai et al. in 2006 showed that flavonoids in lotus seeds might be responsible for their antioxidant potential. The flavonoids may destabilize the harmful free radicals (molecules in the body) and reduce oxidative stress by removing the free radicals from the body. This would reduce the risk of several diseases like diabetes, heart disease, liver disease, etc.1,6 However, more studies are required to check the antioxidant potential of lotus seeds.
Though studies show the benefits of lotus seed in various conditions, these are insufficient, and there is a need for further studies to establish the true extent of the benefits of lotus seed on human health.
