1, liquid gold-olive oil
The consumption frequency of olive oil in China is relatively low, but this does not mean that olive oil is not good. On the contrary, the health of olive oil is called gold grade.
In many Mediterranean countries, olive oil is their standard. Why is olive oil healthy? This is because olive oil has a high content of oleic acid, which is an unsaturated fatty acid and a "good fat".
Olive oil is made by cold pressing the fruit of olive, which retains the most natural nutrients of olive and the original nutrients of olive.
However, the boiling point of olive oil is relatively low, and high temperature will destroy the nutrients of olive oil. It is recommended to eat olive oil when cooking cold salad or spreading bread.
2. Oriental olive oil-rapeseed oil
Rapeseed oil is very common in daily life, and many families have a special liking for rapeseed oil. The taste of rapeseed oil is more in line with the taste of China people, but you must not know that ordinary rapeseed oil is actually recognized as one of the healthy oils in the world.
The definition of healthy oil is that the content of saturated fatty acids is low, because saturated fatty acids are harmful to human body, and rapeseed oil is the most reasonable proportion of fatty acids in all edible oils.
One of the main reasons for the health of rapeseed oil is the high content of unsaturated fatty acids, which is very beneficial to our health. Not only that, rapeseed oil can also moisturize in autumn and winter, helping to reduce the fat in the blood.
3. Advanced nutritional oil-sunflower seed oil
Everyone must eat melon seeds often, but there is little sunflower oil. Sunflower seed oil is actually a melon seed family. Friends who often eat sunflower oil will find that melon seeds and sunflower oil taste very similar.
There is an acid in sunflower oil called linoleic acid. This acid can lower cholesterol and prevent many diseases of the elderly. Not only that, it can also protect the health of the skin.
Precautions for daily oil use:
1, select oil according to cooking temperature.
Cooking oil has a very important index, which is smoke point. The higher the smoke point, the higher the temperature it can withstand, and the less likely it is to produce toxic substances formed by violent oxidation.
Different cooking methods have different temperatures, so in order to avoid harm to health, it is natural to choose oil that meets the smoke point.
For example, olive oil and rapeseed oil with the lowest smoke point are more suitable for cold dishes or hot dishes. The high-temperature cooking methods such as stir-frying and frying are naturally peanut oil with the highest smoke point, and soybean oil is more suitable.
2. Don't fry in fried oil.
I believe many families will do this, because they will consume more oil in the process of frying food, so they will save the used cooking oil for the next cooking.
Although this method is economical, in the process of frying, the oil has been heated at high temperature, resulting in trans fatty acids and toxic oil oxides. If fried at high temperature, it will produce more harmful substances, which is naturally unhealthy.
Of course, the oil that has been fried once will not be wasted. Similar to this kind of "cooking oil", it is more suitable for mild cooking methods such as water frying and soup making, and reasonable and healthy saving is the correct behavior.
