I cannot do without my range of cooking oil. From regular olive oil to rice-bran oil, coconut oil, and mustard oil, my pantry is fully stocked at all times. Since oil is one of the essential things seen in the kitchen, we often forget to pay much attention to it. Over the years cooking has taught me not just about taste and flavors but also the importance of using the right oil at the right time. I have also learned by spending many hours in the kitchen, reading cookbooks and browsing the Internet several interesting facts about cooking oil.

So here I am listing 16 questions about your daily cooking oil in a Q&A manner


1. Can Cooking Oil Go Bad?

Oil packages come with a ‘best before’ date but it doesn’t necessarily mean that the oil will go bad after that date. In fact, you can continue using the same oil for quite some time after that as well. But yes, it can go bad after some time, especially if you have opened the packaging. An unopened pack can last two to three years, by rough estimation.


2. Can Cooking Oil Be Reused?

Reusing cooking oil is a common practice but it can pose certain health hazards. Reused oil can get spoiled, have strange flavors and may also contain carcinogenic free radicals. When I have to reuse it, I make sure to always drain the oil through cheesecloth to remove any food particles floating. I make sure never to over-heat the oil, especially if I have plans of reusing it and I never mix two types of cooked oil together. I do not use iron or copper pots and pans if I plan on reusing oil as these metals can accelerate rancidity.


3. Can Cooking Oil Catch Fire?

Yes, the oil can catch fire if it becomes too hot. Therefore I never leave the kitchen if I am heating oil for deep-frying. I always keep a kitchen thermometer handy so that I know at what temperature the heat can get dangerous. Learning about the smoking points of different types of cooking oil is advisable.



4. Are Cooking Oil Gluten Free?   

Cooking oils generally do not contain gluten – a grain protein mostly found in rye, wheat, and barley. If you are gluten intolerant, it means that it can cause mild to serious damage to your digestive tract. Though cooking oils are gluten-free, they may contain traces of it if the oil is manufactured at a facility that makes gluten-containing foods.


5. How Much Cooking Oil is Healthy?

I being very particular about my family’s oil intake had done a quick research and found this. According to RDA (Research Data Alliance), a person must have a 20-30 g intake of oil every day. Since almost every food item has a certain percentage of fat content, that must be taken into account when you plan your meals.


6. Which Cooking Oil is Best for Diabetes?

Diabetes is on a rise in India and if you or a family member is affected by this slow killer disease, making healthy diet choices is a necessity. Every type of cooking oil comes with its own set of health benefits but for diabetes, you must keep in mind the oil’s effect on a person’s glucose and fat metabolism. Some of the best cooking oils for diabetes include –

  • Almond oil
  • Canola oil
  • Flaxseed oil
  • Macadamia nut oil
  • Olive oil
  • Sesame oil
  • Walnut oil

7. Which Cooking Oil Repairs Memory?

If brain health is one of your main concerns while choosing cooking oil, switch to regular olive oil. As a plant-based oil, it is known for its high polyunsaturated and monounsaturated fatty acids – both of which are linked with good cognitive health. However, you must keep in mind that olive oil is high in calories so using it in small quantities is advisable. Moreover, olive oil’s benefits are reduced when heated which means it is ideal for cooking chicken and making salads.

Flaxseed and walnut oil have low smoke points and can ideally be used as salad dressings and in dips.
