Was born in the 70 ‘s before you would remember every household stove sits in a tank, big or small, sheng was eating at the time. When the temperature is low, it lard cemented white; at higher temperature, above into oil; when the temperature is too high, the whole jar of oil. When cooking, put a tablespoon of oil in a pan, perfume. At that time every family with lard or oil not people like to eat animals, but, when a planned economy, for the common people, not just buy what you want to buy, want to buy as much as you can buy. Want to buy need food stamps to eat, and buy sugar sugar and cloth need cloth ticket, buying oil needs oil, … …. Everyone has half a catty of oil per month, an average of less than 10 grams per day. Have enough oil to do? Buy meat! Meat is actually rationing, no oil in the belly, what should I do? Working people are wise, buy meat to fat when, and for what? FAT to eat, of course, more importantly into lard, to make up for the shortage of supply. There is also a byproduct of the refinery, which is diesel. Also delicious, just refining of diesel oil, and sugar, and what a sweet, sweet! Oil can also be used to wrap the buns, dumplings, n. How delicious is not, but the food supply, but of.
When you cook with oils of animal and plant two. Chinese residents ‘ regular consumption of animal fats are lard, butter or suet, regular consumption of vegetable oils oil, rapeseed oil, peanut oil, sesame oil, and corn oil, olive oil, sunflower oil in recent years. Cooking oil is indispensable to our daily diet food and cooked food not only by the change in cooking oil and cooked, and improve taste, can also promote increased appetite and satiety.
From the point of view of nutrition, cooking oil is important for our health, and performs a number of physiological functions:
1, to provide energy.
2 provide fat, animal fat 90%, also contain. Vegetable oils containing fatty 99%, does not contain cholesterol, and is the primary source of our residents ‘ e.
3, fat is an important component of the human body, a weight of 14%~19% is adipose tissue in healthy adults, it protects the organs, subcutaneous fat tissue to maintain a constant body temperature.
4, fat still constitute the main components of the brain, nervous system, and has important relationships and human fertility.
5, fat-soluble vitamins a, d, e and k absorption and utilization.
80 ‘s of last century after reform and opening up, China’s rapid economic development and constantly improve people’s living standards, the food supply increasingly rich people can buy whatever I want to eat, many families with uncontrolled or excessive oil in cooking oil. Survey found that last more than 30 years, the vegetable oil consumption of urban and rural residents in China increased by more than 20 grams, the current average of more than 40 grams of cooking oil consumption per person per day, has been well above the China Guide to dietary 25 g or 30 g of recommendation. Meanwhile, Chinese residents ‘ dietary patterns are “Westernized”, too many animal foods such as meat and fat consumption, excessive fat intake will affect the health of our residents. Is caused by too much fat,, such as risk factor for many chronic diseases. Compared with 1992, overweight adults in China has increased by 39%, obesity has risen by 97%. Edible oil consumption, reduced physical activity and other factors are factors that contribute to chronic disease increases, rather than less because we eat lard!
As the animal and the kinds of fatty acids in vegetable oils containing different, have different effects on health. In General, the fat with the higher level of saturated fatty acids, longer carbon chain, higher melting point. Animal fats containing saturated fatty acids, solid at room temperature, such as pigs, cattle, sheep oil, a few plants such as coconut oil, palm oil, also contain saturated fat. Saturated fatty acids contain more cholesterol and saturated fatty acid intake, high blood cholesterol, triglycerides, and the main cause of low density lipoprotein cholesterol, arterial stenosis caused by secondary, formation of atherosclerosis, increase the risk of cardiovascular disease. Therefore, generally saturated fatty acids in animal fat and high cholesterol should eat less.
More unsaturated fatty acid in vegetable fat, it is liquid at room temperature, such as. Unsaturated fatty acids including monounsaturated and polyunsaturated fatty acids, was of great benefit to human health. Body needs essential fatty acids are polyunsaturated fatty acids can be synthesized EPA,DHA and EPA and DHA can improve learning skills of children, enhances memory. In addition, the unsaturated fatty acids reduce blood fat in the body, improves blood circulation, inhibiting platelet aggregation and inhibition of atherosclerosis and Thrombosis and other effects, has a good effect on cardiovascular disease.
Different vegetable oil fatty acid compositions of different nutritional characteristics of different vegetable oils. For example, olive oil and higher levels of monounsaturated fatty acids of Camellia oil, corn oil, and sunflower oil are rich in linoleic acid, soybean oils rich in linoleic acid and alpha-linolenic acid are two essential fatty acids. Linoleic acid and α-linolenic acids reduce blood fat and cholesterol. Due to a single fatty acid composition of different nutritional characteristics are different, the type of cooking oil should be regularly replaced, eat a variety of vegetable oils.
There are many factors affect health, nutrition, physical activity, environmental and so on. Changes in the health of the residents in China, mainly related to nutrition, physical activity and other lifestyle changes. Therefore, we should do a reasonable diet, eat poultry, eggs, lean meat, these animals are high quality protein, fat-soluble vitamins and a good source of minerals. Eat less fat and lard, lard is high in energy and fat foods, eating too much can lead to overweight and obesity, and increased incidence of chronic diseases such as diabetes, Dyslipidemia, and balanced the proportion of saturated fatty acids and unsaturated fatty acids, pay attention to the intake of some special functions of fatty acids on the other, must change their lifestyles, enhance physical activity, maintaining a healthy weight.
