Groundnut Health Benefits, Nutrition, Varieties, and More

Groundnuts, a nutritious powerhouse, are difficult to resist nuts with a high protein content. They are members of the pea family and are used in a variety of culinary traditions.

Groundnuts are multitaskers, serving as both a human food source and a food source for animals. They are also edible oilseeds due to their high oil content. They are high in nutrients that are healthy to the heart.

Groundnuts thrive in the tropics and subtropics. They grow underground pods. As a result, botanist Carl Linnaeus dubbed them “hypogaea,” meaning “beneath the ground.”

Did you realise that peanuts, a common pantry item, are a type of groundnut? Peanuts, roasted, are a favourite snack. This groundnut is also used as the key component in a variety of different meals, including peanut butter, peanut oil, peanut flour, and protein powder.

Groundnut Varieties

The groundnut family includes a wide range of nut cultivars. They are classified based on selected breeding, geographical location, and compositional distinctions.

Groundnut from Bambara

Bambara groundnut, technically known as Vigna subterranea, is a Fabaceae family groundnut cultivar. It is a type of legume native to West Africa.

Drought-tolerant Bambara groundnut is an affordable source of dietary protein. As a result, cultivation is cost-effective due to its subsurface resources, which are high in carbs, protein, and fat.

Bambara groundnuts are more resistant to climate change, illnesses, and pests than other groundnut types. Furthermore, they are readily available in local stores, either roasted or boiled.

At the household level, groundnuts are eaten as a mid-morning or mid-afternoon snack. Furthermore, they are available in cream, white, red, dark brown, black, or a mix of these colours.

In Africa, the mature seeds are ground into flour. As a result of its high protein content, Bambara groundnuts are a great addition to food and beverages.


Peanuts, commonly known as Arachis hypogaea, are a type of peanut. As a result, it belongs to the groundnut family. Peanuts and groundnuts are both high in oil and nutrients. The pods of most groundnuts can be circular or cylindrical, whereas peanut pods are cylindrical.

The applications and qualities of groundnut and peanut may differ. Peanuts, for example, are widely used as a snack, confectionery, butter, and nutritional supplement.

The principal uses of groundnut, on the other hand, are cooking oil extraction, herbal supplements, and snack items. Peanuts are not further classified, however groundnuts are divided into Hausa groundnut and Bambara groundnut.

Groundnut from Hausa

Hausa groundnut, also known as tiger nut, is a perennial groundnut that is eaten as a snack. This species of groundnut, which is common in Madagascar, Asia, Europe, and Africa, can be eaten raw, boiling, roasted, or baked.

Groundnuts from Hausa are used to manufacture flour, non-alcoholic milk drinks, starch extracts, butter, and oil. It has detoxifying properties comparable to peanuts. If you are lactose intolerant, the Hausa groundnut milk drink may be ideal for you.[1]

The great nutritional properties of Hausa groundnut make it a valued commodity in the Western market. Its high iron and vitamin C content may help to combat malnutrition and avoid anaemia. Hausa groundnuts, like other nuts, are high in unsaturated fat. It is also an important source of protein for vegans.

Groundnut Health Benefits

Having Healthy Skin

Eczema and other inflammatory skin disorders benefit from groundnuts. It is high in fatty acids and antioxidants, which help to preserve the skin by combating free radicals.

Furthermore, the vitamin C concentration of groundnuts promotes the creation of collagen in our bodies. A proper level of collagen keeps the skin’s suppleness and firmness. As a result, consuming a handful of groundnuts every day helps to keep the skin healthy and smooth.

Lowers the risk of cardiovascular disease

Groundnuts include unsaturated fats, which are good for you. These are polyunsaturated and monounsaturated fats, respectively. They also provide protein, fibre, and minerals such as magnesium, folate, thiamin, and vitamin B6. These nutrients are necessary for heart health.

Resveratrol, a powerful antioxidant found in raw and roasted groundnuts, aids in the prevention of heart disease. It minimises cellular damage and protects people with cardiovascular disease.

Resveratrol possesses anti-inflammatory, antioxidant, and antithrombotic effects. They work in tandem to reduce inflammation in the body. Groundnut resveratrol also aids in the prevention of angiotensin-induced blood vessel damage.

Peanuts are abundant in flavonoids such catechin, epicatechin, luteolin, and apigenin. They may aid in lowering harmful LDL cholesterol by 30-40%. Surprisingly, those with 10% lower cholesterol have a 20% lower risk of heart disease.

Enhances Mental Health

Groundnuts are high in vital nutrients for the brain, such as polyunsaturated fats, monounsaturated fats, and vitamin B3. These nutrients are essential for brain health and memory enhancement.

According to one study, niacin aids in the prevention of age-related memory loss, such as Alzheimer’s disease. People who consume a lot of groundnuts may have a lower risk of Alzheimer’s.

They may even have a good memory. Furthermore, vitamin E from groundnuts is used by our brain as an antioxidant to protect it from chemical breakdown. As a result, regular brain functioning and memory are ensured.

Enhances Male and Female Fertility

Groundnuts are high in folate, which helps males become more fertile. Men’s fertility is directly related to sperm quality, sperm count, and libido.

According to one study, males experiencing fertility troubles who consumed 5mg of folic acid and 66 mg of zinc sulphate for 26 weeks saw a 74% rise in sperm count.

Groundnuts include fatty acids that aid in blood circulation in the genitals and aid in erectile dysfunction—omega6 fatty acids aid in improving reproductive cell structure.

Magnesium is abundant in groundnuts. Magnesium is also responsible for female fertility and the good development of the foetus. Magnesium aids in the nourishment of the uterus by boosting blood flow to it.

It also regulates hormonal levels, particularly the pregnancy hormone “progesterone,” which aids in the conception of a healthy pregnancy.

Magnesium shortage can cause spasms in the fallopian tube, which can prevent egg implantation. Furthermore, the folate found in groundnuts is advantageous both before and after pregnancy. As a result, folate and magnesium have a synergistic influence on fertility.

Assists in Weight Loss

Groundnuts are energy-dense foods that make you feel satisfied and aid in appetite regulation, minimising calorie intake through wasteful food nibbling.

Furthermore, the protein content in groundnuts aids in increasing metabolic rate. A fast metabolism aids in weight loss by burning calories in order to perform all physical activities effectively. As a result, increased metabolism aids in weight loss by burning extra calories.

Aids in Depression Treatment

Tryptophan, an important amino acid that increases serotonin production, is found in groundnuts. It is a molecule that regulates mood by having antidepressant properties. As a result, consuming enough groundnut will raise serotonin levels in the blood and trigger antidepressant effects.

Uses for Groundnuts


Fresh groundnuts can be boiled with salt. Boiled groundnuts have a nice scent and are easy to digest. For pregnant women, the best way to prepare groundnuts is to boil them.


Frying is a popular cooking method among teenagers and young adults. Groundnuts are steeped in saltwater for around 30 minutes before being totally strained.

To retain heat and get a toasted texture, use fine sand while frying groundnuts. It may, however, promote protein denaturation and increase fat content.


Sprouted groundnuts aid in weight loss. Sprouting also increases the Vitamin C and B content of groundnuts. It is a good source of nutrients for geriatric and paediatric diets.

To begin, soak groundnuts in warm water for 10 minutes. Then, after draining the warm water, do the following:

  • Soak the groundnuts in cold water for 12–20 hours before draining thoroughly.
  • Set it aside in the shade and cover it with a cloth.
  • For the next 8-10 days, properly rinse and drain with cold water. The sprouts can then be harvested after 10 days.

Weight Gain as a Possible Side Effect of Groundnuts

Excessive consumption of groundnuts on a daily basis may result in weight gain. Groundnuts are high in calories, with 564 calories per 100 grammes. It is recommended to consume 12-25 groundnuts each day. If you consume more groundnuts while burning less calories, you will eventually gain weight.


Some people are allergic to peanuts and other groundnuts. An allergic reaction causes the immune system to develop exacerbating mechanisms against the proteins found in groundnuts.

Rashes, swelling, stomach discomfort, hives, redness, or itching may occur as a result. Groundnut allergy symptoms can range from moderate to severe.

Anti-Nutritional Factors

The majority of groundnuts contain phytic acid, which is a type of phosphorus. Phytic acids are also known as anti-nutrients because they prevent the body from absorbing iron, zinc, magnesium, and calcium.

It also reduces protein digestibility in the body. As a result, the body may suffer from mineral deficiencies, as well as allergies and intestinal discomfort.

Contamination with Aflatoxin

Aflatoxin contamination, a form of carcinogen produced by a mould called Aspergillus Flavus, occurs during the groundnut harvest season. It may be harmful to the liver.

It has even been linked to an increased risk of liver cancer and jaundice. Post-harvest chemical treatment aids in the reduction of aflatoxin concentration in groundnuts.


Groundnuts are high in calories, protein, carbohydrates, dietary fibre, and oil. Furthermore, groundnuts are an oilseed crop that is widely consumed around the world. Groundnuts can be eaten raw, soaking, or roasted and are used in a variety of dishes.

Polyunsaturated and monounsaturated fats are beneficial to the heart. They also lower the risk of heart disease and stroke. It also enhances male and female fertility, keeps blood sugar levels stable, and decreases harmful LDL cholesterol.

Eating in moderation is the greatest method to limit the likelihood of negative effects while also providing your body with all of its essential nutrients. Unfortunately, our immune system sometimes perceives groundnut protein to be dangerous. As a result, it may exhibit negative effects, resulting in certain allergies.

As a result, skin responses, itching, runny nose, and hives may occur. People with asthma, ulcers, joint disorders, allergies, and toddlers should avoid eating groundnuts unless their doctor has given them permission.
