canola oil

Canola oil, which is poor in saturated fats and rich in omega-3 and omega-6, is one of the oil options that can be preferred. Canola oil also contains vitamins E and K.

Since its smoke point is higher than olive oil, it can be preferred in dishes that require higher temperatures.


Butter, which has a great place in Turkish cuisine, is rich in saturated fat compared to other oils. It is also rich in vitamins A, D, E and K, which are fat-soluble vitamins. Despite its high caloric value, it is a low-nutrient food.

Due to its high saturated fat content, its consumption should be limited, as excessive consumption can cause heart diseases and weight gain.


Margarines, which are offered as a healthier alternative than butter because they do not contain cholesterol, are actually composed of trans fats. It has been proven that trans fats carry serious health risks. The U.S. Food and Drug Administration has requested that trans fats are unsafe and removed from all packaged foods.

The biggest danger from trans fats is their capacity to disrupt cell membranes. The most serious disease caused by T-fat consumption is coronary heart disease.

While most dietary fats are classified as long chain triglycerides, coconut oil contains medium chain triglycerides, which are shorter chains of fatty acids.

Medium-chain fatty acids are a type of fat that our body metabolizes differently from other fats. They are quickly digested and used as a direct energy source and converted into ketones. It is known that ketones can have powerful benefits for the brain.

Medium-chain fatty acids are responsible for most of the health benefits of coconut oil.

It is known that coconut oil can help with weight loss by supporting fat burning, as well as heart and brain health.

tahini and sesame oil

Sesame oil is a type of oil with a high antioxidant content, and with this feature, it can protect cells and reduce the risk of heart diseases. It is also effective in providing blood sugar regulation. Sesame oil not only adds flavor to the food to which it is added, but also increases its nutritional value.

There are two types, refined and unrefined. The unrefined type can be used for lower and medium heat cooking, while the refined type is more heat stable and suitable for cooking at higher temperatures.

Another source of oil obtained from sesame is tahini. Tahini is a healthy fat group alternative that is rich in healthy fats, vitamins B1 and B6, and minerals and antioxidants such as phosphorus and manganese.
