Use Unrefined Versions

Use more of ‘Kacchi Ghani’ or Unrefined and /or Cold-pressed versions instead of Refined Oils. The production process for Refined Oils involves a lot of Chemicals, Stabilizing Agents, and High Temperature that destroy the nutritional value significantly and leaves us with just empty Calories.

What is the Smoke Point and can Oils be Reused?

Heating the Oil during cooking, to a point where it starts to burn and gives off smoke is called Smoke Point. Each Oil has its own Smoke Point, and when it's heated beyond or past that Point, it results in two undesirable effects.

  1. The Oil starts losing its Flavour and Nutrients.
  2. A reaction called Oxidation takes place and develops a harmful substance called Free-radicals.

Used Cooking Oil

Used cooking oil is basically the extra oil that has been left after cooking and which we hesitate to throw away as Oils are an expensive commodity and not keeping it after just one use is not cost-effective. Hence we end up reusing it a couple of times before discarding. But this is not advisable to reuse leftover oil from frying of food. It is important to note that since it has already been used at a high temperature earlier, it contains small food particles and other remnants. Storing this oil for reuse at a later date will only lead to a further decrease in the properties and flavor of the oil and an increase in the harmful substances. Similar to the Smoke point, reheating Used Oil also leads to a reaction called Oxidation, that too at a faster rate, leading to decrease in the quality of oil.

Expert Tips

  • Avoid heating of oils to a very high temperature and not let smoke come from it.
  • Always choose shallow frying or sautéing to reduce oil usage and Avoid having leftover used cooking oil.
  • Try to fry in smaller batches to use a little amount of oil at a time and then add more as per need.
  • Store the leftover oil in an airtight container to limit its contact with air to reduce the damage that can happen.

Oils and Diabetics

Oil is one of the most commonly used ingredients in cooking. Whether it is roti-sabzi, baked products, fried items, or anything else, oil is an item that no household can run without. On TV, we see several advertisements that now talk about healthier oils, oils that will not lead to health-related complications. This simply attests to the fact that oils can be unhealthy. They contain different types of fats and are converted into fatty acids in the body. 

Oils have high inflammatory properties. They contain omega-3 and omega-6 fatty acids. Both of these fatty acids have opposite functions. Omega-6 causes inflammation and increases the potential threat of onset of diabetes. Omega-3, on the other hand, fights any inflammation and prevents the onset of diabetes. Therefore, choosing cooking oils for diabetes that are richer in Omega-3 fatty acids would be a better option. Sesame oil, Groundnut oil, Sunflower oil, Mustard oil, etc would be good options for persons with diabetes.

Avoid certain plant oils like – corn oil, rice bran oil, etc as they are associated with an increased risk of obesity, heart conditions, arthritis, etc. Additionally, also ensure to take a look at the oil packets and keep a check on the trans fat content.
