Desi cooking has been dominated by two nourishing cereal grains - rice and wheat, since ancient times. And although not cooked as frequently as the common chawal or atta, the ubiquitously grown, rather minute-sized and equally healthy corn, features prominently in the list of all the staple ingredients in Indian kitchens, amid other whole grains, pulses and legumes.
Yet another cereal grain, corn is an age-old harvest crop, that was first grown by the natives of Mexico thousands of years ago and has been cultivated in many countries since the past several centuries. Known commonly as maize and bearing the scientific name Zea mays, the tiny kernels or seeds of corn, which are technically the fruits, occur in large clusters encompassed within elongated inflorescences termed as ears.
Commonly referred to as maize or corn, this nutrient-dense plant produce has several local names within the Indian subcontinent. Popular as spicy evening snacks in the form of namkeen, corn flakes mixture as well as boiled, seasoned with salt, pepper and eaten as corn on the cob, it is termed as “Makka” in Hindi, “Mokkajonna” in Telugu, “Cholam” in Tamil, “Bhutta” in Bengali. The semi-soft texture, roughly round shape and versatility of corn makes it ideal to be eaten as such, as well as processed and cooked in different ways like light-weight fluffy popcorn, crunchy savoury snacks, flattened breakfast cereals, fine powdered corn flour or corn starch.

Corn/Maize Health Benefits:
Augments Eye Health
Corn comprises a vast array of key antioxidants, namely carotenoids lutein and zeaxanthin. These scavenge harmful free radicals from optic tissues and enhance eyesight. In addition, they protect the delicate organelles of the eye from damage, preventing vision disorders like glaucoma, age-related macular degeneration.
Supplies Essential Amino Acids
Corn is composed of certain key amino acids, making it a unique plant-based source of high-quality proteins. It offers methionine, a sulphur-based amino acid to revive skin and hair health, valine and isoleucine which repair injured muscle tissues and threonine, to enable the proper formation of teeth and enamel.
Supports A Gluten-Free Diet
A significant number of young adults and older people tend to develop intolerance towards the gluten proteins in cereals like wheat, that, unfortunately, is a regular ingredient in Indian dishes. Corn, being organically gluten-free, can easily be substituted for wheat, to prepare chapatis, dosas and sweets or mithais, and is often recommended for patients with celiac disease.
Fortifies Bone Density
Corn being a fantastic source of natural calcium, strengthens bones in growing children. It also restores optimum bone density in older people, assisting in alleviating osteoporosis symptoms. While younger people can consume corn daily, middle-aged and older adults need to eat measured servings of corn, to augment bone health, while steering clear of gastrointestinal and kidney disorders.
Keeps Blood Sugar Levels In Check
Corn, although being high in calories and carbohydrates for instant energy, also comprises a plethora of phytates, tannins, polyphenols – plant chemicals that slow down the digestion process. This lowers high blood sugar in those with diabetes mellitus. Also, owing to its low digestibility and rich fiber content, corn is indeed a healthy option for accelerating weight loss and managing other lifestyle diseases like diabetes and obesity.
Treats Anaemia
Iron deficiency anaemia affects countless Indian men, women and children every year, leading to excessive fatigue and low productivity levels. Corn is a powerhouse of iron, serving as a boon for people who experience low haemoglobin levels in the blood, thus effectively treating anaemia.

Boosts Nervous System Function
Eating corn in controlled portions on a daily basis assists in enhancing nerve impulse conduction, activating memory centres in the brain and relaxing the mind, due to elevated levels of the amino acid tryptophan. As the tryptophan brings about an equilibrium in the levels of serotonin – a neurotransmitter, corn helps in treating anxiety and insomnia, by maintaining good moods and promoting sound sleep.
Augments Heart Health
Corn is completely devoid of cholesterol and sodium, so recipes made with cornflour can safely be consumed by those with heart ailments. Furthermore, the abundance of dietary fibers and vitamin B3 or niacin helps to enhance good HDL levels and diminish bad LDL levels. This averts plaque and fatty deposits in heart vessels, easing cardiac muscle function and improving heart health.
Ensures Healthy Pregnancy
Consuming measured portions of corn has massive benefits for the health of pregnant and lactating women. Due to the immense iron and calcium content in corn, it is ideal to stimulate milk production and balance hormonal activities in expecting women and young mothers.
Contributes To Healthy Weight Gain
The comprehensive nutritional content in corn makes it a perfect food for meeting a growing child’s ever-expanding nutrient requirements. Corn on the cob is often served as a snack after intense physical activities, to young kids, to facilitate optimal growth and development. Owing to its starchy content, corn influences healthy weight gain in young children, assisting in their routine development.
Promotes Gut Health
Many people suffer from unbearable stomach pain along with abnormal bowel movements, diarrhoea, flatulence and constipation. Corn is blessed with the goodness of dietary fibers, that enhance gastrointestinal functions. Eating foods with increased fiber content positively influences bowel movement, regulating faecal bulk and promotes optimal passage of food and other materials within the intestines. In this manner, corn stimulates healthy metabolism and digestion.
Treats Hypertension

Effect On Doshas
Corn kernel, in essence, has a madhura rasa (sweet taste) with intrinsically laghu and ruksha gunas (light and dry qualities).

Moreover, it fosters the positive and equalizing states of mind namely sattva and rajas, effectively eliminating tamas or a negative mindset.
Therapeutic Applications
Lowers High Blood Pressure
Being rich in dietary fibers, corn flushes out Ama toxins from improperly processed foods and hence circumvents them from getting clogged in blood vessels namely arteries, veins and capillaries. The unobstructed transport of blood and nutrients to and from the heart is thus facilitated, lowering high blood pressure i.e. hypertension.
Remedies Liver Dysfunction
Corn is heaped with antioxidants, which provide for the prompt removal of harmful free radicals from the system, especially in the liver and gallbladder. In this manner, a balance between the bodily tridoshic states is attained wherein all unwanted fatty accumulations are wiped out of the body, ensuring healthy liver function.
Ameliorates Depression Symptoms
Comprising neurotransmitter regulating properties, corn efficiently boosts the positive state of mind - sattva and suppresses lethargy or tamas. This works wonders in uplifting moods, sharpening the intellect and rehabilitating the brain from depression symptoms.
Uses Of Corn Flour For Skin And Hair:
Aside from being a panacea for practically every illness bothering the internal organs in the body, cornflour also enhances the external appearance by revitalizing skin and strengthening hair.

This promotes new skin cell formation, concealing fine lines and wrinkles. In addition, the vast reserves of amino acids in cornflour help boost collagen, maintaining suppleness and smoothness of the skin.
Cures Hyperpigmentation
Applying a herbal mask of cornflour with some milk and honey or other natural infusions is a superb solution to get rid of suntans, UV ray damage and irregular skin complexion, due to the skin-tightening, protective and rejuvenating traits of corn.
Reduces Acne And Boils
Corn is imbued with tannins, which are plant compounds with anti-inflammatory qualities. Thus, it aids in decreasing acne, pimples and boils, besides brushing away dark spots and scars.
Prevents Hair Fall
Consisting of formative amino acids such as methionine and lysine, a corn hair mask as well as eating corn in the diet enriches hair growth and renews texture of tresses. This controls hair fall and averts premature greying and balding.
Anti-Dandruff Solution
Corn possesses innumerable essential amino acids and carotenoids that confer useful hair growth and anti-microbial characteristics when applied as a herbal paste to dandruff-prone scalp.
