Understanding of food nutrition. Food nutrition is very important to us. Now when we choose nutritious foods, we should focus on foods with low calories, low fat, high dietary fiber, vitamins and minerals. The following

Look at the understanding of food nutrition.

Understanding of food nutrition 1 1. Food nutrition and health, focusing on human body structure and physiology, explains all the nutrients contained in common foods that are beneficial to the body, build body tissues and organs, and meet the needs of human life activities, as well as these nutrients

Effects and effects on the human body; 2. With the rapid development of nutritional science, life science, food science, etc., research on healthy food ingredients and the relationship between diet and disease has been continuously expanded widely and deeply. By improving

Dietary conditions and food composition, and the physiological regulatory function of food itself to improve human health have increasingly become people's awareness.

Food nutrition is as relevant to everyone as a diary or a paycheck.

It can determine your appearance, words, deeds, and mood, whether you are melancholy or happy, beautiful or mediocre, clear or confused, mentally or physically young or old; whether you are happy or bored at work; whether you are innovative and seek change or stick to the rules, etc.

It’s all about nutrition.

What you eat every day can determine whether you feel happy or exhausted after a long day at work.

Simply put, it can affect your life. The better the nutrition, the richer the harvest.

Food is the basic source for the human body to obtain the required heat energy and various nutrients, and is the material basis to meet the body's nutritional needs.

The nutritional value of food usually refers to the extent to which the nutrients and heat energy contained in the food can meet the nutritional needs of the human body, including whether the types of nutrients are complete, the content and their mutual proportion are appropriate, and whether they can be digested, absorbed and utilized by the human body, etc.

Multiple layers of meaning.

In daily life, there are many kinds of food with different nutritional ingredients and contents. Different groups of people have different needs for nutrients, so the nutritional value of food is relative.

Therefore, in the past, people were accustomed to measuring food according to its nutritional content by the content of a single nutrient.

With the continuous progress of society, people's concepts of nutrition have changed significantly. Most people are paying more and more attention to the reasonable combination of nutrients and the diversification of food. The dietary choices of people with different nutritional needs have

Guiding significance.

The 20 kinds of food are divided into 4 categories. Among them, there are 4 kinds of food in the first category, mainly grains. Their nutritional characteristics are relatively high carbohydrate content and low vitamin content. They are the main source of heat energy required by the human body;

There are 14 types of food in the second category, including vegetables, meat, milk, fish, etc. It is a type of food with relatively balanced nutrient content. In addition to containing the three major energy-supplying nutrients of the human body, it can also provide a certain amount of minerals and

Vitamins; eggs and kelp are classified into one category each, which reflects the particularity of the nutritional content of these two foods. It shows that among common foods, the types or contents of nutrients contained in them are difficult to replace by other foods. Among them, kelp is mainly for the human body.

It provides a large amount of mineral elements, such as calcium, iron, iodine, etc., and eggs are one of the most ideal foods for the human body. They are not only balanced in nutrients, rich in high-quality protein, but also rich in vitamin A.

Judging from the above classification results, it is very similar to the nutritional point of view. Therefore, it is believed that cluster analysis can integrate multiple nutritional indicators to evaluate food nutritional types, and can intuitively analyze the Euclidean dissimilarity coefficient and dendrogram.

By grasping the similarity of nutrients between foods, the conclusions drawn can provide a theoretical basis for reasonable daily dietary matching, provide dietary guidance for people with different dietary needs, make human dietary structures more reasonable and the diet more diverse, and achieve the purpose of a balanced diet.

People who blindly pursue fashion in diet often disdain nutrition.

Most of them believe in folk rumors and secret recipes that have no scientific basis and exaggerated and false advertisements, and follow what others say. Not only do they deny the advice of experts, but they also make people who are concerned about nutrition doubtful and confused.

Those who pursue fashionable gourmet food blindly satisfy their appetites but do not cherish their own health.

I drank a grass juice that tasted like hay. It smelled great but tasted unflattering.

They seem to think that nutritious foods are unpalatable. In fact, the more I study nutrition, the more I believe that for healthy people, all foods are delicious.
