It is hard to determine the difference between the two kinds of oil while cooking or tasting food, but both of them have different nutritional content, physiological and chemical properties.
Manufacturing process
Since the process does not involve an excessive amount of heat or chemical solvents, cold-pressed oils retain their original flavor, taste, aroma, and nutritional value. Not only the oil is highly beneficial for your cardiovascular health, but also your skin when topically applied. On the contrary, regular refined oils are extracted by using high temperatures and treated with chemical solvents that degrade their flavor, taste, and nutritional composition.
Nutritional value
Cold-pressed oils are rich in essential fatty acids, antioxidants, vitamin E, vitamin K, vitamin C, and other healthy fats as they preserve the potent nutrients of their ingredients and maintain their natural form. While consuming cold-pressed oils can protect the heart by reducing bad cholesterol and blood pressure levels, intake of refined oils in everyday diet can increase the risk of strokes and heart attack significantly.
Shelf-life
Regular oils undergo a hydrogenation process and are further treated with harmful chemicals to increase their shelf-life and yield capacity. On the other hand, since cold-pressed oils are unfiltered and minimally processed, they have a shorter shelf-life and produce a lower yield. For this reason, hot-pressed or regular oils are relatively cheaper than cold-pressed oils with greater quality.
Cooking method
Cold-pressed oils are suitable for food prepared in medium to low heat due to their low smoking points whereas hot-pressed oils are preferred for preparing meals at high temperatures due to their high smoking points.
Making a switch from regular oil to cold-pressed oil can be difficult and expensive, but this little transformation can make a big difference to your health and well-being. Some of the cold-pressed oils to include in your diet for good heart health are coconut oil, olive oil, sunflower oil, groundnut oil, flaxseed oil, walnut oil, borage oil, etc.
