Oils have been an indispensable component of our diets since ancient times. Extracted from both plant and animal sources, edible oils provide critical nutrition to our bodies while enhancing the flavors of our food. In this article, we will explore the various types of edible oils commonly used, their nutritional properties, health benefits as well as some tips for safe usage.

Types of Edible Oils

There are numerous Edible Oils that are extracted from different sources across the world. Some of the major types include:

Vegetable Oils
- Soybean Oil: One of the most versatile oils, soybean oil is mild in taste and high in polyunsaturated and monounsaturated fats. It has various health benefits and is used widely in cooking and baking.

- Canola Oil: Derived from rapeseed, canola oil is bright yellow in color and light texture. It contains healthy monounsaturated and polyunsaturated fats that can reduce bad cholesterol levels.

- Sunflower Oil: Known for its neutral taste, sunflower oil has a high smoke point making it suitable for stir frying and deep frying. It contains vitamin E and antioxidants that can protect cells from damage.

- Olive Oil: The mainstay of Mediterranean diets, olive oil contains monounsaturated fatty acids that can lower risks of heart disease and stroke when consumed in moderation. Its subtle flavor also enhances the taste of foods.

- Coconut Oil: Extracted from coconut meat or kernel, coconut oil remains solid at room temperature due to its high saturated fat content. It has antimicrobial properties and supports thyroid and brain health.

Animal Oils
- Butter Oil: Derived from butter, butter oil has a rich dairy taste and contains fat soluble vitamins like A, D, E and K. It adds moisture and tenderness to baked goods.

- Ghee: Clarified butter widely used in Indian cooking, ghee has a higher smoke point than butter. It aids absorption of fat-soluble nutrients and supports bone, brain and heart health.

- Lard: Rendered pork fat with a mild meaty taste, lard creates flaky textures in baked goods. It contains saturated fats which provide energy when consumed in moderation.

Nutritional Benefits of Edible Oils

While dietary fats have received negative attention in the past, certain oils can benefit our health when consumed as part of a balanced diet:

- Monounsaturated (MUFAs) and polyunsaturated fats (PUFAs) found in oils like canola, olive and soybean can help reduce levels of bad LDL cholesterol and risks of coronary heart disease.

- Oils rich in omega-3 fatty acids like flax and chia seeds support brain and nerve health while also aiding metabolic functions and reducing inflammation.

- Vitamin E antioxidants in sunflower, safflower and corn oils protect cells from oxidative damage and boost immunity.

- Medium-chain triglycerides in coconut oil aid absorption of fat-soluble vitamins and minerals while promoting energy levels.

- Conjugated linoleic acid in ghee and butter may decrease fat accumulation and promote weight maintenance.

Thus, judicious inclusion of right types of oils tailored to individual needs provides several health advantages when consumed as part of balanced, nutritious diets.

Cooking with Edible Oils

Besides direct consumption, edible oils also add appeal and enhance nutrient bioavailability when used for cooking:

Sautéing and Stir Frying: Oils with higher smoke points like canola, avocado and rice bran are suitable for sautéing and stir frying meat and vegetables. The antioxidants remain intact at higher temperatures.

Deep Frying: While not healthy as a regular practice, occasional indulgence in deep fried foods demands oils with smoke points over 400°F like peanut, corn and sunflower oils for maximum nutrition and crispness.

Roasting: Drizzling olive, sesame or nut oils on meats, fish, grains and veggies before roasting infuses rich flavors while keeping foods moist. The antioxidants are well retained.

Baking: Oils act as tenderizers and carriers of fat-soluble vitamins in baked goods. Unsaturated oils like soy, sunflower, corn and olive are healthier substitutes for butter or shortenings.

Marinades: Lime juice and avocado or olive oil based marinades add zest while tenderizing meats and vegetables on the grill or in oven.

Choosing and Storing Edible Oils

To maintain quality and maximize benefits of edible oils, some basic storage guidelines must be followed:

- Cold pressed and virgin oils retain maximum nutrients and should be refrigerated after opening.

- Highly processed oils can be stored in cool, dry places away from direct sunlight for 2-6 months.

- Check best before dates and replace oil if it develops any unpleasant smells on storage.

- Tinted bottles, dark containers or opaque jars are best as light degrades oil quality faster.

- Consume oils within a few months of opening to prevent oxidation and rancidity.

Conclusion

In moderation as part of balanced diets centered around whole foods, different types of edible oils provide critical micronutrients and support overall health. Their inclusion elevates flavors and aids nutrient absorption from other foods. By choosing healthier unsaturated varieties and following proper storage methods, we can continue harnessing oils' nutritional benefits for improved wellness.
