No one is perfect for food. We would like to have a variety of nutrients that will only be obtained by eating the right type of food. What do our bodies need?
Scientists have identified 40 different types of nutrients in food.
With the exception of very few foods that are almost entirely made up of one nutrient, the vast majority of foods we eat are a mixture of many nutrients. However, each food group included in the pyramid (grains, fruits, vegetables, dairy products, and meat) is unique among the types of nutrients that contribute to our diet. For example, fruits and vegetables are the most common sources of many vitamins, minerals, and carbohydrates in our diet, so the meat group (including dried beans, legumes, eggs, poultry, and fish) is the main source of protein for many people.
It is often difficult to distinguish between the nutrients themselves, and therefore the foods they contain. For example, once you've heard from nutritionists about the need to produce more complex carbohydrates, what do these foods mean and what foods do they contain? In this chapter, we specialize in the nutrients themselves: how they are digested, what happens to them inside the body, and what they do for you. We also use the simplest food sources for every nutrient, because after you go to the supermarket, do not look for protein, starch, fiber, and antioxidants - look for chicken and rice, cold cereals and fruit juices.
Nutrients are categorized according to the idea of their chemical composition and functions. Carbohydrates, proteins, and fats present in food are called macronutrients because they are required in large quantities. Additionally, for its other functions, macronutrients provide energy within these types of calories. Vitamins and minerals are called micronutrients. Your body needs it in much smaller quantities. Although micronutrients help your body use energy in macronutrients, they do not provide energy (calories) per se. In addition, water is an important nutrient without calories. The work that our bodies do every day makes us exhausted
Some of our stories contain these essential nutrients. Only by maintaining a diet rich in many foods that contain nutrients, we can replace these lost nutrients.
In addition to known nutrients, the substances found in plant foods, which are called phytochemicals or phytonutrients (the image is the Greek word for plant), are identified in
Recent studies. These phytochemicals can promote health and help prevent some diseases. Many of these compounds are identified in fruits and vegetables,
The nuts, beans, and grains we eat, although only a few have been carefully studied. The impact of these various phytochemicals on our health may be a promising new area for nutritionists.
Both macronutrients (carbohydrates, proteins, and fats) perform different functions within the body's function. In addition to its unique functions, all macronutrients provide calories. Once we eat more protein, carbohydrates, or fats than we want to replace what we used, the surplus is converted and stored as fat. Calories will not match all muscular activities, to stop metabolic reactions that support the body, to keep the blood warm, and support growth. But once we absorb calories more frequently than we use, we gain weight. Weight is kept when the amount of energy (calories) between energy production is balanced.
