Derived from seeds of vegetables and fruits that have oil content, these oils have become a rather important part of the diet for most. Whether you use it as a cooking medium such as frying, as a shortening agent for baking, or a salad dressing; they are a good source of healthy fat. Overall, vegetable oils provide a plethora of benefits such as reducing the risk of cardiovascular diseases, better metabolism, and digestion and provides omega-3 fatty acids to the body.
Let’s look into the nutritional composition and health benefits of vegetable and fruit oils to understand this and break away certain popular myths.
Nutritional Value of Vegetable Oils
Various oils have different nutritional components that help us but there are common elements such as vitamin E (Tocopherol), omega-3 and omega-6 fatty acids, polyunsaturated, monounsaturated, and saturated fats. 
Health Benefits of Vegetable Oils
After the nutritional components, let’s understand how they benefit our health and why we should include vegetable and fruit oils in our daily diet.
Promote Cell Growth
Oils like safflower, cottonseed, sunflower, almond, and wheat germ are all rich in vitamin E which is required in the body for cell protection and development. This vitamin has a long list of benefits for our body. From improving the immune system to stimulating the digestive system, it is vital. It protects body tissues such as skin, eyes, breasts, testes, and liver.
Prevent Heart Conditions
Polyunsaturated and monounsaturated fats are the most frequently found forms of fat in vegetable oils. Polyunsaturated fats help lower bad cholesterol levels and reduce the risk of cardiovascular diseases. Further, the presence of vitamin E in the oils helps in preventing heart diseases and eliminating blood clots which are the cause of heart ailments. 
The body requires fatty acids to carry out various functionings, and vegetable oils provide these in abundance. There are two types of fatty acids, namely, omega-3 and omega-6. The body doesn’t produce these naturally; hence, acquiring it from food is essential. Alpha-linolenic, a type of omega-3 fatty acids, are found in soybean, canola, and flaxseed oil which are very similar to the fatty acids in fish.
Omega-3 fatty acids are widely known to be anti-inflammatory which is why they are highly recommended for people suffering from chronic heart, skin and digestive concerns. On the other hand, omega-6 is pro-inflammatory, which is also required but long-term use beyond advised quantities can cause more harm than help. A ratio of 1:1 is ideal to maintain health and avoid complications. However, many people consume an unhealthy ratio of 16:1, an unbalanced number of omega-6 and omega-3 fatty acids which has been correlated to various diseases including inflammatory issues, and autoimmune diseases, and chronic diseases.
