Nutrition is the biological and metabolic process through which an organism utilizes food to sustain its existence. It includes absorption, assimilation, metabolism, biosynthesis and excretion. It is said that every living thing has a fixed nutrition, which helps them in their growth, development, maintenance, growth and lifespan. It is also called the macronutrient. The major food groups are protein, carbohydrates, vitamins, minerals, fat, fiber and water.

The major food choices include proteins, vegetables, fruits, legumes, dairy products and oils. This information was used in the NIEHS study session on nutrition, one of the largest ever conducted on the health and nutritional needs. An estimated two million adults and children were involved in the study. The participants were asked a number of questions pertaining to their food choices and the nutrient intakes. The study session 2 nutrients focus was on identifying the sources of nutriments and evaluating those sources for nutritional value.

An important aspect of human nutrition is determining the energy intake, known as dietary energy intake (Diaries, 2021). Another aspect of human nutrition is ensuring that the right foods are consumed with the right amounts. The main article focuses on these two aspects. The main article discusses the meaning of macronutrients.

In a nutshell, macronutrients are units of nutrients that are needed by the organisms in their different stages of life. Macronutrients include proteins, carbohydrates, vitamins, minerals and fats. The NIEHS study identified 4 major macronutrients and they are carbohydrate, fat, fiber and vegetable protein. The main article discusses the importance of each of these nutrients in providing healthy weight management.

Carbohydrates are divided into three categories which are simple sugars, complex carbohydrates and starchy carbohydrates. It is important to remember that all plants contain varying proportions of carbohydrates. The main nutrients in plant nutrition that are affected by carbohydrates include starch, fiber and sugar. In recent years, researchers have concentrated on carbohydrate richness which refers to the extent to which an object’s molecules are made up of carbohydrate. The main article discusses the types of carbohydrates and how their effects on human nutrition are determined.

The main article discusses the importance of fat in human nutrition. Fat provides the energy that is required by the body for day-to-day activities. The main nutrients in animal foods that are rich in fats are omega 3 fatty acids, sterols and vegetable oils. The main article discusses the factors that affect the fat content in foods.

The main article continues to discuss the sources of nutrition for the people in the world. These sources are whole foods that can be eaten in any form like fresh fruits, vegetables, seeds, nuts, legumes, grains and seeds. The other sources of nutrition include dairy products, meat, poultry, fish and bones. Whole grain foods are recommended, as these provide a good level of carbohydrates, protein, vitamins and minerals in the diet. The other thing to note is that all of these foods must be consumed in the right proportion.

The other factors that affect the nutrients in the diet include the variety of the food that has been consumed, the time since they were eaten and the amount of the nutrient that was consumed within a specific period. For example, it is not recommended to eat more vitamins A or B vitamins than needed due to the fact that B vitamins are found in some foods faster than the vitamin A. Therefore, there are certain sources of these vitamins that are more appropriate to be included in the diet.

Another factor that is very important in diets is fats and carbohydrates. The fats and carbohydrates are required to provide energy for performing different activities and this is also necessary for the proper growth of the body. Both of these are available in various forms. Some of the most popular fats and carbohydrates are oatmeal, milk, peanut butter, lean meats, vegetables, fruits and whole grain foods. However, the amount of each of these varies depending on the type of weight loss program that a person is undertaking.

Another important thing is to note is that the amount of fat or carbohydrate that is consumed by people has a great role in controlling the increase of the levels of vitamins and minerals. For example, if the person is on a low-fat, low-carbohydrate diet then the body tends to intake more fat or carbohydrates than what one needs. This leads to accumulation of fat and carbohydrates in the body and thus resulting in weight gain. Conversely, when a person is on a high-fat, high-carbohydrate diet, then the body tends to absorb more vitamins and minerals from the food as compared to what one requires. This results in the loss of weight because more nutrients are used than what is needed.

A balanced diet has been identified as one of the most effective ways to lose weight. It is recommended that people should eat foods that are low in fat and carbohydrates but at the same time should also take supplements that contain vitamins and minerals as well as amino acids. Amino acids include peptides and small amounts of proteins like whey, casein, eggs and chicken. They also play a major role in regulating blood pressure and are important in regulating the immune system. Hence, people who are looking for effective methods to lose weight should start their research session on micronutrients today.
