This ingredient should not exist in food! Is endangering the health of billions of people.

The foods of more than 5 billion people contain harmful industrial trans fats, which are unsaturated fatty acids that may occur in natural or processed foods. Trans fats are produced when solid fats such as margarine are produced by hydrolyzing oil. Heat treatment of vegetable oils also produces trans fats, and hydrogenation of vegetable oils produces trans fatty acids. Trans fatty acids appear on the market under a variety of names, and we usually see food labels with zero trans fatty acids if the content of trans fatty acids is less than 0.3 grams per 100 grams of food. So it still depends on whether there are ingredients such as margarine, vegetable fat powder and plant cream in the list of ingredients. The state stipulates that the intake of trans fatty acids does not exceed 1% of the daily calories. Oil heated to a certain extent also produces trans fatty acids. It's not easy to avoid this health barrier in your diet?

Fat is a substance that people love and hate. We love its flavor wanton, love it can bring nutrition and energy to the body, but the love of fat often "good intentions do bad things", accidentally exceeded the standard, leading to obesity, high blood pressure, heart disease and a series of problems.

In the classification of fat, there is a "devil" fat-trans fatty acids, which always enter our bodies quietly, thus killing our health.

More than 5 billion of the world's 8 billion people eat foods that contain harmful industrial trans fats, increasing their risk of heart disease and death, according to a report released by the World Health Organization.

So, what is the "trans fat" that World Health Organization (WHO) "criticizes"?

What is trans fat?

Trans fats, also known as trans fatty acids, are unsaturated fatty acids that may occur in natural or processed foods.

In the field of processed food, trans fats are produced when solid fats such as margarine are produced by hydrolyzing oil. Heat treatment of vegetable oils also produces trans fats.

Foods that contain a lot of trans fats include baked goods, sweets, fried potato products and ready-to-eat foods.

Where do trans fats come from?

Hydrogenated vegetable oils produce trans fatty acids, which we call hydrogenated vegetable oils. Trans fatty acids appear on the market under a variety of names, such as cocoa butter, shortening, margarine, margarine, vegetable fat, etc., all made from hydrogenated vegetable oils.

Generally speaking, we see zero trans fatty acids on food labels, but that doesn't mean it is 100% free of trans fatty acids. The General rules for the labelling of prepackaged Food stipulates that if the content of trans fatty acids in every 100 grams of food is less than 0.3 grams, it can be marked as zero. So it still depends on whether there are margarine, vegetable fat powder, plant cream and other ingredients in the list of ingredients. The state stipulates that the intake of trans fatty acids does not exceed 1% of the daily calories, which translates to two grams.

In daily life, when we cook food, the oil is heated to a certain extent will also produce trans fatty acids, it is recommended that we try to cook at a low temperature, hot pot cold oil, try to avoid hot pot hot oil.

Where do trans fats come from?

Although many people are aware of the dangers of trans fatty acids, it is not easy to avoid this health barrier in their diet, because it is widespread in many foods, and three types of "hideouts" are easy to ignore.

1. 5 kinds of foods contain natural trans fatty acids

Natural trans fatty acids are rare in nature, and the food contribution rate is only 28.83%. The medical community has not yet made clear its relationship with human obesity and cardiovascular disease, so as long as a little attention is paid to it, there is no need to avoid eating too much. Excessive resistance to natural trans fatty acids may lead to insufficient sources of nutrition and increase the risk of malnutrition.

The five foods that contain natural trans fatty acids are beef, mutton, milk, goat milk, breast milk and so on.

2. Trans fats are widely found in desserts and fried foods.

The most common types of desserts and fried foods in daily life contain trans fatty acids. After all, trans fatty acids from processed sources contribute as much as 71.17%. The details can be divided into: candy, pastry, biscuits, puffed foods, snacks, beverages, condiments (salad dressing, solid soups), breakfast (Youtiao) and so on.

3. Pay attention to "hidden" trans fatty acids

Now that many people are aware of the dangers of trans fatty acids, they pay special attention when looking at the list of ingredients, and to deal with this situation, businesses have come up with an alternative strategy to change their names. In fact, margarine, vegetable shortening and all vegetable oils that contain the word "hydrogenated" (hydrogenated soybean oil, hydrogenated palm oil, hydrogenated vegetable oil, etc.) in the ingredient list are only "substitutes" for trans fatty acids.

What is the best intake of trans fat?

Trans fatty acids can not be completely avoided, people can only try to control the total intake within a safe range, to close to the goal of protecting health. So what is the upper limit of daily intake of trans fatty acids?

A study by the World Health Organization found that the human body consumes only 1% of the total energy of trans fatty acids. The Dietary guidelines for Chinese residents recommend that adults eat no more than 2 grams of trans fat a day.

We can follow these two standards, reasonable planning of dietary structure, the overall goal is to ensure adequate nutrition, trans fat can eat less.

The existence of trans fatty acids was originally a pursuit of food, but it ended up creating a health barrier, but now it is almost ubiquitous and has become an eating habit of many people, so it is not easy to say "no" to trans fatty acids. Remind everyone: the pursuit of good food is a pleasure of life, but we should also face up to the harm of trans fatty acids, pay attention to improve their eating habits, learn to plan nutritional supplements, and be a happy "dry rice man".
