Groundnut oil, also known as peanut oil or arachis oil, is a vegetable oil that has many uses: 

Taste and appearance

Groundnut oil is a light yellow, transparent oil with a pleasant fragrance and taste. 

Composition

Groundnut oil is high in monounsaturated fat and low in saturated fat. It contains over 80% unsaturated fatty acids, including 41.2% oleic acid and 37.6% linoleic acid. 

Uses

Groundnut oil is used for cooking, as a shortening, and as a base for confectioneries. It's also used to make peanut butter. 

Smoke point

Groundnut oil has a high smoke point (437°F or 225°C), making it a popular choice for frying foods. 

Flavor

Groundnut oil has a mild or neutral flavor, but if made with roasted peanuts, it has a stronger peanut flavor and aroma. 

Groundnut oil is easy to digest and absorb because of its fatty acid composition. 

Origin

Groundnut oil is derived from the edible seeds of the peanut plant, which is a member of the bean, pea, or legume family. 

 Peanut oil can have some health benefits, but it also has some potential disadvantages: 

Heart health

Peanut oil is high in monounsaturated and polyunsaturated fats, which are considered "good" fats. These fats can help lower LDL cholesterol, which can clog arteries and lead to heart disease. 

Vitamin E

Peanut oil is a good source of vitamin E, an antioxidant that can help protect the body from free radicals, which can damage cells and cause some cancers and heart disease. 

Blood sugar

Some studies have linked unsaturated fats to improved blood sugar levels in people with diabetes. 

Hair growth

The vitamin E in peanut oil can strengthen hair follicles, reduce damage, and prevent dandruff. 

Omega-6 fatty acids

Peanut oil is high in omega-6 fatty acids, which are important for health but are also plentiful in the standard American diet. Consuming too much omega-6 and not enough omega-3 fatty acids may increase the risk of obesity.
