Macro and Micro Nutrients

During this week, I heard somebody asking the purpose of protein in a shake or a smoothie. His friend confidently answered: “Because is the main nutrient for your body to get energy”. I answered to myself: “yes and no.” It is a nutrient, but it doesn’t provide you energy. People have a misconception of nutrients. Not every nutrient provides energy.

Types of Nutrients

These nutrients are divided into two categories:

  • ·         Macronutrients, which are required by the body in large amounts.
  • ·         Micronutrients, which are required by the body in small amounts. Macronutrients

Macronutrients

Macronutrients provide energy to a living being for the function of the metabolic system. They provide massive energy as it is converted used to obtain energy. Macronutrients include:

Fats: the main role of fat is to provide structure and cushion to cells and membranes. Fats help to prevent damage to the human body by providing cushions. Fats are also crucial in helping to absorb certain vitamins. Vitamins A, D, E, and K are the only fat-soluble vitamins. The rest of the vitamins are water-soluble.

Proteins: the main role of protein is to provide your body with the building blocks to build cells and other tissues. Protein gets broken down into amino acids which mainly get used for growth, development, repair, and maintenance of body tissues. Protein provides structure to muscle and bones. Good sources of protein can be found in beef, pork, chicken, fish, beans, eggs, dairy products and some vegetables in few quantities.  

Carbohydrates: the main role of carbohydrates is to provide energy and fuel for your body much like gas provides fuel for a car. Carbohydrates are made up of sugars or starches that are bound together. Your body breaks down those carbohydrates mainly into glucose which is the main form your cells use for energy. Carbohydrates are found in fruits, grains, rice, beans, and numerous vegetables.

Micronutrients

Micronutrients provide essential components for metabolism to be carried out. They also build and repair damaged tissues in order to control the body process. Micronutrients include minerals and vitamins.

Minerals and Vitamins: the main role of vitamins and minerals is to support overall health and play an important role in cell metabolism and neurological functions. Vitamins help to aid in energy production, wound healing, bone formation, immunity, and eye and skin health. Minerals also perform a vast array of functions in the body such as providing structure to the skeleton, helping to maintain cardiovascular health, and also to act as cofactors in enzymatic reactions.

Exercising Fasted: Good or Bad?

Image
Last week, I had to experience my workout on an empty stomach. I’ve never tried it because my schedule was 4:00-6:30 p.m. But my schedule has recently become a little too busy with my social project, classes, and tasks. That day, I had only two choices. Don’t go to the gym or go early in the morning. The answer was clear to me, and I was there before 7 o’clock in the morning. My mom was heading to work when she suddenly stopped me and asked: “Where are you going? You don’t have to give classes today is Friday”. I told her the plan and disappointed said to me: “But you haven’t eaten yet. Eat something!”.   I just answer: “I’ll be fine”. Back at home, I asked myself: “Is it really bad?”. Then, I took some time to investigate if it’s safe to lift weights on an empty stomach.  Is it safe or dangerous? According to an article in Strenghtlog , it is safe, if you're in good health, you can engage in various activities without eating first. This includes physical activity, intense ...

Storytelling

An adventure! S ometimes, plans never result as expected. My teammates agree to record the storytelling in Lago de Coatepeque but not me. Because of it I knew that voice recording could be impossible with all the restaurants and the water waves’ noise. In the place, my mates realized it and decided to ask what’s the most tranquil part of the lake. A man made us an offer, we could take us for 20 dollars to the part of private ranchos of the lake for an 1 hour. We accepted the offer. We arrived at the place, and we found the owners of the place enjoying the weekend. We were afraid that they could say something, but they didn’t just let us record, they also borrowed us an atarraya for utility. Mr. Mario help us not only with the correct usage of the atarraya and how to wear a matata , but also waited for us an extra hour. He find out we were not lying with the recording story, and he gift us an extra hour. We had so much fun recording, it was a pleasant activity.

Can I Get Something for You?

Welcome to The Protein Pub. Party of one? In this blog, I want to share my experience and clear up misconceptionsand myths that some people might have about nutrition, workout, supplements, and anatomy for having a healthy lifestyle.  Before starting, I want to make you, guys, acknowledge that I am not a professional on the subject, yet I have tried different ways of losing weight, building muscle and strength since I was fifteen years old.  I started worrying more about my physique in high school because I felt ugly and uncomfortable with myself, so I started trying to lose weight in an unhealthy form. I stopped taking meals. For breakfast, I usually dunked a cookie in coffee and that was it, and I always skipped lunch and waited until I get home to eat something lighter.   I never lost wight because this practice fires back in different ways, and I wasn’t aware of it. First, it does the opposite to what you are thinking of. It causes your metabolism to slow down, w...
