Carbohydrates and proteins
By now you probably know very well that both proteins and carbohydrates are essential for the development of virtually all vital functions agents. However, you know exactly what they are and how they act inside the body?
If you do not know the answer to this question pays close attention to this article because in it we will solve all your doubts.
Definition of protein and carbohydrates
The first thing you want to do before entering the field, is to define, as clearly and simply as possible, these two important concepts that will relate this article.
The proteins are macro molecules formed of long chains of amino acids, according to their physical and chemical properties, can be simple or complex. In fact, there is a huge variety and are involved in all processes of the body, being essential for growth and the immune system, for example.
The carbohydrates, also commonly known as sugars, saccharides or carbohydrates, are bio molecules that receive this name to be composed entirely of carbon atoms, oxygen and hydrogen. Its main function is to provide immediate and structural energy to all living beings, being glucose and glycogen storage primary forms.
What is the role of protein in your diet?
If you consider that proteins are, in short, the main raw material that has the body to perform its vital functions, it will not cost you understand that they must play a leading role in any healthy and balanced diet. And, in general, these molecules are responsible for manufacture and maintain healthy bones, skin, hair, muscles and, ultimately, any element that is part of your body.
Your body is not ready for direct use protein you consume through food. In fact, once the food is in your stomach, your digestive system proceeds to break the peptide bonds of these amino acids to work with separate and form new protein structures that will be useful itself. In general, there are 20 types of amino acids. Clearly, the meat contains a greater number of proteins that plants and also these are better quality because they contain all essential amino acids, which does not mean that those who follow a vegetarian diet can not obtain them, much less. At this point we must say that the essential amino acids are those that the body can not synthesize themselves, while non-essential itself.
What is the role of carbohydrates in your diet?
Obviously physiological reactions that occur in your body, from your heartbeat to breathing action, need energy to be performed, where one of the substrates are carbohydrates. Thus, in intense and sport activities, they are the main “fuel”, and more, saving protein, avoiding use this for other purposes other than their own.
There types of carbohydrates important properties to maintain the health of the intestinal tract and microbiota, such as the fiber.
No wonder that many people associate carbohydrates to fat action. In fact, there are many who confuse with fat, although not directly related. This is mainly due to its excessive consumption, which in this regard should be adjusted to each person according to their energy expenditure. In any case, consumption and transformation into glucose and glycogen provides immediate energy and storage that your body needs to continue its activity.
Carbohydrates and proteins: a calorie is a calorie not always
Calories are units of measurement used to quantify the energy they bring us food and therefore, is inevitable at this point, talk about the caloric value of these two types of macro molecules. In this sense, you are probably surprised to learn that, in both cases, this value is exactly the same as every gram of both carbohydrates and protein provides 4 calories total. This amount may seem high, but it is nothing when compared to the 9 calories representing each gram of fat.
You may think that, even though your body needs both protein and fats, consumption of these can be harmful to you if you want to lose weight, which is a serious error. And, although you do not know, proteins rarely are stored as fat. In fact, they not used as a direct power since its purpose is the creation of tissues, hormones and enzymes. Meanwhile, only carbohydrates are transformed into fat when consumed in excessive amounts so because, although differently, are also consumed in all physiological functions. In any case, making an adequate amount of daily exercise, which will be healthy for many other reasons too, it is possible to prevent stored as fat.
What are the best sources of protein and carbohydrates?
An average adult must consume daily (based on weight and physical activity) a number of proteins ranging between 60 and 80 grams, ie, the equivalent of three fillets of chicken medium size. However, the amount of protein needed daily will vary depending on the activity of the person, so it will be much higher than the previous recommendation.
Meanwhile, these numbers grow significantly in the case of carbohydrates since it is estimated that between 40 and 60% of daily calories you consume must come from this source. The main sources of carbohydrates are found in foods such as oats, rice and whole wheat bread. Ultimately, that is, roughly speaking, all the essentials you should know about carbohydrates and proteins, two types of bio molecules that your body needs to perform its functions constantly. Therefore, even if you`re dieting, you should not neglect their consumption because, as I have explained, do not have to get fat.
