Is your daily fat intake exceeding the standard?

Editor in charge: Food Science

In the first two content, Professor Lirong Shen from the School of Biosystems Engineering and Food Science of Zhejiang University said that the intake of staple food should be thicker (for details, please click-if you want to stay in shape and want to dry meals, follow the professor of nutrition at Zhejiang University.

A small bowl of chicken rice can make the oil intake "popular"

Still starting from the last lunch (saying that this meal happened for a long time.

He pointed to the oily tofu roasted pork on his plate: “Look, I don’t eat this kind of fat.

Youtiao and milk tea, why don't experts recommend eating it?

What are the problems caused by eating too much oil? The most obvious is obesity, and obesity can induce a series of cardiovascular diseases

So, how do we eat oil?

Oil is one of the three major nutrients of the human body, but it also has good and bad points

Professor Shen said: “Saturated fat is more in relatively cheap pastry products.

"Like on New Year's Day, some younger generations will give cakes to their elders; some elderly people try to save trouble, usually eat cakes to cushion their stomachs, or even deal with a meal; in fact, many cakes are high in oil and sugar, and also contain a lot of saturated fatty acids.

Some people may argue that some Chinese pastries are made with lard, and the price is quite affordable.

One spoon of lard (about 12 grams) contains 5 grams of saturated fat, 5.

Many people think that "Lard was often eaten because of the lack of substances, and there were fewer people suffering from heart disease and cardiovascular disease.

The main component of lard is fat.

In view of the daily intake of saturated fatty acids contained in other animal foods, excessive intake of lard can easily cause saturated fatty acids to exceed physiological needs

Therefore, Professor Shen suggested that people who like to eat lard should strictly control their intake each time, and it is best not to exceed 10 grams each time
.

How to eat oil for three meals and which oil is healthier?

Daily edible oils can be divided into animal edible oils and vegetable edible oils.
For example, butter, tallow, and lard are animal oils, and soybean oil, rapeseed oil, peanut oil, olive oil, and camellia oil are vegetable oils

"A certain dose of animal oil (saturated fatty acids) is beneficial to the human body
.
Excessive consumption of animal oil will have a negative effect
.
The ratio of animal oil and vegetable oil of 3:7 is reasonable as the edible oil for ordinary people
.
"
What kind of oil is suitable for what kind of person? Professor Shen will also share with you a wave of daily scientific methods of eating oil
.
If your three meals a day have a lot of meat and vegetables, such as pig, beef, lamb, chicken, fish, etc.
, try to use vegetable oil when cooking
.
People who mainly eat vegetable dishes can use some animal oils such as lard, and they can choose vegetable oils or animal oils with higher saturated fat content in their daily diet
.

Patients with cardiovascular disease should use animal oil as little as possible, especially those with atherosclerosis or people with high blood fat and high blood pressure
.

What kind of oil is the top student, can you add more daily?

Professor Shen said: "Although the price of these oils is a bit high, you should eat more if possible: olive oil and camellia oil rich in monounsaturated fatty acids; linseed oil and walnut oil rich in omega 3 polyunsaturated fatty acids, etc.
Edible oils
.
These edible oils rich in unsaturated fatty acids help reduce the risk of chronic diseases such as cardiovascular and cerebrovascular diseases, obesity, and diabetes
