Cooking oils play a pivotal role in our daily culinary endeavors, adding flavor, texture, and essential nutrients to our meals. However, not all oils are created equal when it comes to their impact on our health.

What Are Vegetable Cooking Oils?

Vegetable oils are liquid fats derived from various sources such as seeds, fruits, nuts, and grains. These oils are extracted through processes like pressing or solvent extraction. Some of the most commonly consumed vegetable oils include sunflower oil, olive oil, canola oil, palm oil, safflower oil, coconut oil, corn oil, peanut oil, cottonseed oil, and soybean oil etc.

Why Oil is Necessary for Cooking?

Cooking oils are used as a base ingredient. They infuse dishes with rich, aromatic flavors with enhancing the texture of cooked foods, from crispy to tender, depending on the cooking method. Oils help regulate cooking temperatures, preventing foods from sticking to the cooking surface and ensuring even heat distribution. Moreover, oils facilitate the absorption of vital nutrients like fat-soluble vitamins (A, D, E, and K) by the body, promoting overall health and wellness. 

Side Effects of Cooking Oils

Excessive consumption or the use of certain types of oils can have adverse effects on health:

High Caloric Content: Oils are calorie-dense, with each gram containing approximately 9 calories.

Over Weight and Obesity: Overconsumption can contribute to weight gain and obesity.

Increased Risk of Heart Disease: Oils high in saturated and trans fats can raise cholesterol levels, increasing the risk of heart disease and stroke.

Digestive Issues: Certain oils may cause digestive discomfort and contribute to gastrointestinal issues when consumed in excess.

Potential for Oxidative Damage: Heating oils to high temperatures can lead to oxidative damage, producing harmful compounds that may contribute to inflammation and chronic diseases.
