Question: What is saturated fat?
Answer: The carbon atoms within the structure of the saturated fats form 4 chains and these are called saturated fats. The saturated fats are much in the fats such as margarines, butter and etc. and they cause cardiovascular disorders by blocking your veins as a pipe is blocked with lime.
Question: What is unsaturated fat?
Answer: The unsaturated fats are divided into two groups as the single and multiple unsaturated fats. The single unsaturated fats are formed by engagement of only two carbon atoms through double bounds. The single unsaturated fats (for example, the hazelnut oil, olive oil and etc.) prevent the cardiovascular disorders. They help decreasing the LDL that is known as the harmful cholesterol in the body and increasing the HDL that is known as the useful cholesterol and reducing the total cholesterol. They are protective against cancer. The multiple unsaturated fats are formed by engagement of more than two carbon atoms through double bounds with each other. The oils with multiple unsaturated fat rates (for example, the soya oil, the sunflower oil, the corn oil and etc.) prevent the cardiovascular disorders, help decreasing the LDL that is known as the harmful cholesterol in the body and increasing the HDL that is known as the useful cholesterol, reducing the total cholesterol, have useful impacts in the treatment of hypertension and are protective against carcinogenic disorders.
Question: What is Omega 3, Omega 6 and Omega 9?
Answer: They are the unsaturated fat acid groups. They should be taken externally because they cannot be synthesized by the body, itself. They have vital importance for the human health. The Omega 3 and 6 are the multiple unsaturated fatty acids. The linelonic acid is the most important acid of the Omega 3 fatty acids. The linelonic acid is the most important acid of the Omega 6 fatty acids. These acids are present at high levels in the soya, corn, canola and sunflower oils. The oleic acid is the most important acid of the Omega 9 fatty acids. These acids are present much in the hazelnut and olive oils.
Question: What does Cotanak word mean?
Answer: It is the hazelnut on its shoot with green shell. The above mentioned green shell is not the known brown shell of the hazelnut, it is the green and leaflike sac out of that brown shell where there are more than one hazelnuts in it. The cotanak is not known by the people other than the local people because hazelnuts are separated from their cotanak by devices called haymakers right after they are collected and marketed with their brown shell forms.
Question: What are the advantages of the hazelnut oil?
Answer: The most important characteristics of oil are the combustion and freezing degrees and the fatty acid contents. The high combustion degree obstructs the quick decomposition of the oil molecules and generation of free radicals of oxidation has carcinogenic effect especially during frying. Low freezing degree prevent the solidification of oil during the circulation and atherosclerosis. The most important fatty acids are the single unsaturated fatty acids with high levels of oleic acid content that have decreasing impact on the harmful cholesterol while increasing impact on the good cholesterol. These fatty acids minimize the risk of cardiovascular disorders with their above mentioned characteristics. The hazelnut oil is the oil that has the highest combustion degree and the lowest freezing degree among all oils and also contains the highest level of oleic acid within.
Question: How the liquid oils should be kept?
Answer: The decomposition of oils while they are kept waiting is accelerated through the impacts of temperature, air and sunlight. In order to prevent this, the oils that will be kept for a long time, should be kept in close cabinets that do not penetrate any sunlight, cover closed under room temperature.
Question: What should we do with the expired oils?
Answer: The expired oils do not have any direct harmful effects on human health. However, a little rancidity can be experienced in the taste and it can disturb your stomach. It should be returned.
Question: Which oil is healthier?
Answer: Several vegetal liquid oils are healthy in many ways. They have positive effect on the cholesterol and triglyceride levels because their unsaturated fatty acid levels are high. They do not cause any cardiovascular disorders. They do not cause any carcinogenic effect because they do not contain any trans fatty acids. The animal fats such as butter and tallow and margarines contain high amounts of saturated fat and trans fatty acids. They have negative impact on the cholesterol and triglyceride levels. They impose a risk for the cardiovascular disorders and cancer. Some vegetal oils such as the cotton oil, date oil, coconut oil and palm oil contain high levels of saturated fatty acids because of that reason, these oils should be avoided.
Question: What is the trans fatty acid?
Answer: They are extremely dangerous fatty acids that are in some kinds of oils with their carcinogenic effects that develop when some oils are processed under hydrogenation or processed under high temperatures. They are in animal oils such as butter or tallow and margarines.
Question: Is the extra-virgin olive oil is superior than all other oils?
Answer: The olive oil is among the highest quality oils with the hazelnut oil. However, the extra-virgin olive oil is a kind of oil that is marketed as it is first extracted without any refining process, consequently it is a kind of olive oil that includes some harmful materials in all oils such as the free fatty acids, wax, stearin, soapy materials and etc. Therefore, this oil is not such a perfect oil as it is reflected to the public opinion.
Question: Is the light-colored oil light?
Answer: The coloring materials that are naturally in the oil are removed through the decolorizing process. These materials do not have any impact on the quality of oil. It is possible by performing the deodorization process well. Consequently, it cannot be said that the light-colored oil is also light and the color of oil is not a quality criteria.
Question: What kinds of oils should be used for healthy nutrition?
Answer: The World Health Organization (WHO) recommends that %30 of the daily required calories should be provided from fats and %10 of that %30 should be from saturated, %10-13 single unsaturated and %7-10 multiple saturated fats. 1 gram of oil contains 9 kcl (kilo calorie). Although, it changes based on the age, weight and activation speed, the average calorie requirements of a normal adult is daily 1500-2000 kilo calories. According to these information, 450-600 kcl. of that should be taken from fats, in other words, daily 50-65 grams of fat should be consumed. Approximately 3/1 of that amount is within the content of the other foods so this amount is consumed indirectly. Most of the fats consumed by that way through the other foods are the saturated fats. In this case, the remaining 40 grams of fat should be consumed directly as 20-26 grams of single fatty acids and 14-20 grams of multiple fatty acids by adding in the dishes and salads. No diets should be without fat. The liquid vegetal oils are important for your body. Vitamins A, D, E and K should be taken with oils because they dissolve in oils.
Question: What is "ideal oil”? What are the characteristics of it? Which fatty acids are contained at which levels in ideal oil?
Answer: According to the performed researches and authorities, the multiple and single unsaturated fatty acids should be taken at balanced levels for the balanced nutrition and health. Some oils are rich with single unsaturated fatty acids-oleic acid (such as the hazelnut oil, olive oil), while some oils are rich with multiple unsaturated fatty acids-lineloic acid and linelonic acid (such as the sunflower oil, soya oil and corn oil). The ideal oil is an oil that is created through the idea of manufacturing an oil containing both unsaturated fatty acids at balanced levels and consisted of the mixture of the hazelnut and sunflower oils and contains %50-52 oleic acid and %38-40 linoleic and linolenic acid. Because the fatty acid contents of the seeds that the used hazelnut oil and sunflower oil are manufactured are different, the hazelnut oil and sunflower oil rates of the ideal oil may vary. The hazelnut oil contains oleic acid varying in between %77 and %84 while the sunflower oil contains linoleic and linelonic acid varying in between %48 and %74. According to this, in order to obtain the ideal fatty acid composition, %70-80 sunflower oil and %20-30 hazelnut oil are used in accordance with the contents of the raw materials.
Question: How much calories do the liquid vegetal oils contain?
Answer: The calorie level of all liquid oils are the same. There are 9 calories in 1 gram of all liquid vegetal oils.
Question: What kind of health problems may be experienced if the oleic, linoleic and linolenic fatty acids known as the basic fatty acids that are in high levels in some vegetal liquid oils such as the hazelnut oil, the sunflower oil, soya oil, canola oil and corn oil?
Answer: The visual impairment, weakness in learning ability, disorder in motor movements, numbness at arms and legs, skin blushes like eczema, hair loss, weakness in immune system, black lung degeneration, behavioral disturbances, kidney degeneration, excessive perspiration with thirstiness, excessive sensitivity against infections, slow improvement of scars, weakness in sexual virility, miscarriage risk for women, arthritis and similar disorders and diseases, cardiologic (cardiovascular) disorders, growth disorders, desiccation of salivary glands, lachrymal glands and pancreas glands, pigmentation decrease of skin, fragility of capillary veins, damage of muscular tissue, mental disorders, excretory system disorders, bronchial disorders, phrynoderma (goosepimply vesicles on the upper parts of the arms, hips and calves).
Question: Is there any alternative for oils in the sense of tastes of the foods and dishes?
Answer: No alternative has been found, yet.
