Our bodies need carbohydrates, dietary fiber, calories, protein, and fat each gram each day

It is necessary to divide the words of experts into very detailed ones, and the needs of teenagers, middle-aged and elderly people, and children are different.

What I know is also from the book, the average person's daily body needs are: carbohydrates.

500-600 grams.

Dietary fiberboard.

500-600 grams.

Heat. 2600 kcal.

Protein. 72 grams.

Fat 72 grams.

Carbohydrates.

Protein. 72 grams.

Fat 72 grams.

1 g sugars (carbohydrates.

4 kcal, 1 gram of fat, 9 kcal, 1 gram of protein, 4 kcal. To calculate the number of calories in a food or diet, you must first know the caloric nutrients in it.

and then calculate using the following formula:

Calories (kcal) Sugars 4 grams Protein 4 Fat grams 9 Alcohol grams 7

The calories consumed by adults are utilized in three ways: the basal sensitive empty metabolism.

amount, activity level, caloric effect of food.

The growth and pregnancy stages also require additional heat to build tissue.

Each gram of carbohydrates produces 4 kilocalories. Carbohydrates are one of the body's three major energy substances, protein and fat can also produce calories, 1 gram of protein can produce about 4 kilocalories, and 1 gram of fat can produce about 9 kilocalories. Carbohydrates, in particular, are the main source of energy for the body's activities**.

Heat acts like a computer consumes electricity, a truck consumes fuel, and the daily activities of the human body consume heat. In addition to giving people the energy they need for sports, daily work and life, calories also provide the energy needed for human life activities, blood circulation, breathing, digestion and absorption, etc. **People can burn fat through exercise, which can accelerate the consumption of calories to achieve the effect of health**.

Carbohydrates produce caloric energy = 4 kcal.

Protein produces calories = 4 kcal.

Fat produces calories = 9 kcal.

Each gram of carbohydrates produces 7,700 calories, and each gram of calories is about equal to joules; And 1 calorie of energy or heat can raise the temperature of 1 gram of water at one atmosphere by 1 degree Celsius.

Carbohydrates are composed of three elements: carbon, hydrogen and oxygen, and the organic compounds that exist in nature are the most abundant and have broad-spectrum chemical structures and biological functions, which can be expressed by the general formula CX(H2O)Y; Because it contains a ratio of two to one hydrogen to oxygen, like water, it is called a carbohydrate.

The proportion of protein, fat and carbohydrate required by a normal person should account for -60 of the total calories in a day. For normal adults, the daily intake of protein is about 80 grams, fat is about 100 grams, and carbohydrates are about 300 grams.

For normal people, excessive intake of protein will increase the burden of liver and kidney function, increase the level of oxalic acid and blood uric acid in the urine, and increase the risk of suffering from genitourinary stones, gout and other related diseases. In addition, urinary elevation is also very likely to cause calcium deficiency.

Hello. Healthy people, a day carbohydrate intake can not be less than 150 grams (3 taels), experts believe that the scientific diet should be balanced in structure, nutritionally balanced, its protein, fat, carbohydrate ratio should be reasonable. Carbohydrates should provide about 60% of the energy consumed each day, fats about 25%, and proteins about 15%.

It can be seen that carbohydrates account for the largest proportion of them. People should supplement cereals and cereals at every meal, 30% in the morning, 30% in the evening, and a little more at noon, about 40%.

Internationally, it is generally accepted that healthy adults need grams of protein per kilogram of body weight per day. In China, it is recommended to be grams, which is due to the fact that the protein ** in the diet of our people is mostly vegetable protein, and its nutritional value is slightly lower than that of animal protein. The requirement of protein is also related to labor intensity, and the higher the labor intensity, the greater the requirement of protein.

In the supply standard recommended by the Chinese Nutrition Society, men aged 18-45 (weighing 63 kg) who are engaged in very light physical labor should have a daily protein supply of 70 grams; In the case of extremely heavy physical labor, it rises to 110 grams. In people with special physiological conditions, the amount of protein supply also changes. For example, pregnant women who are 4-6 months pregnant should increase their daily protein intake by 15 grams from the original amount; For pregnant women and lactating mothers who are 7-9 months pregnant, add 25 grams on the basis of the original amount.

For patients, on the basis of normal maintenance amount, the characteristics of the disease, disease resistance and tissue repair needs should be considered.

1. ** time, the daily intake of carbohydrates.

Many ** friends refuse to hear fat, and they are afraid that they will gain weight if they consume fat. In fact, fat is also an indispensable and necessary substance for our body, and a reasonable intake of fat is also helpful. Fat provides the human body with the ability to protect internal organs and participate in the body's metabolic activities.

The daily fat intake is between 400-500 calories, but because each person exercises differently and weighs differently, the fat intake is also determined according to individual circumstances during the period.

In short, a reasonable daily intake of a certain amount of corporate carbohydrates, protein and fat is very good for the effect. And for the best people, reasonable exercise is very helpful.

The proportion can be adjusted to 45% carbohydrates, 30% protein, and 25% fat, and the intake of the three major nutrients is indispensable, so we should pay attention to moderation.

For the purpose of fat loss, the calorie ratio of each part should be about 50 calories of carbohydrates, about 30 35 calories of protein, and 10 15 of fat calories. The total daily calorie intake should be based on the individual's height, weight, target weight, and activity level.

The intake of carbohydrates should be kept within 300 grams, the intake of 80 grams of protein is best, and the intake of fat should be 100 grams.

The intake of protein, carbohydrates, and fats should not exceed half a catty per day, and the intake of carbohydrates during the period should be less than 300 grams per day.

Each gram of carbohydrates can provide about 4 kilocalories. The introduction is as follows:

1.Analysis: 1 gram of carbohydrate can produce about 4 kilocalories (4000 calories).

Carbohydrates are one of the body's three major energy substances, in addition to protein, fat can also produce calories, 1 gram of protein can produce about 4 kilocalories, and 1 gram of fat can produce about 9 kilocalories.

2.Natural foods usually contain a variety of nutrients, including the three major nutrients, so the calories of what is commonly referred to as food are usually produced by these three major nutrients. Carbohydrates, in particular, are the main source of energy for the body's activity**.

3.Heat refers to the change of the state of the system and the destruction of the thermal equilibrium conditions, that is, when there is a temperature difference between the system and the outside world, we call the thermal interaction between the system and the outside world. As a result of the action, energy is transferred from a hot object to a low temperature object, and the energy transferred at this time is called heat.

4.Heat and work are two different forms of energy transfer that accompany the change of the state of the system, and they are measures of the transfer of energy in different forms, and they are both related to the intermediate process of the state change, so they are not a function of the state of the system.

What is Heat:

1.The human body consumes energy all the time, and these energies are provided by the thermogenic nutrients in food. The calorie-producing nutrients in food are proteins, fats, sugars, and carbohydrates.

They are oxidized to produce heat for the body to sustain life, growth, development, and movement. When the heat supply is too much, the excess heat will be stored as fat, and after a long time, the body will become fat.

2.The unit of calories: In nutrition, "kilocalories" is used as the unit of calories.

1 kcal is the amount of heat required for 1 liter of water to rise by 15 degrees Celsius. There are three main ways of caloric consumption, the first part is the basal metabolic rate, which accounts for about 65 70% of the total amount of hot jujube and cherry in the human body, the second part is physical activity, which accounts for about 15 30% of the total caloric consumption, and the third part is the thermal effect of food, accounting for at least about 10%, and the proportion of these three has been roughly fixed.
