Carbohydrates, proteins and fats are the three large categories of nutrients that the body requires in large amounts in order to perform its functions properly. All the macronutrient has its own unique function in the human body and provides calories energy.
Carbohydrates
Carbohydrates serve as the primary fuel source for your body. Every time you consume foods such as grains, fruits, vegetables and even sugars, your body transforms those carbohydrates into glucose. This glucose is what your body requires in order to perform its activities.
Simple vs. Complex Carbs
Carbs are categorized into two primary types: simple and complex.
-
Simple carbs, like those in honey, fruits, and candy, give quick energy, but that energy doesn’t last long.
-
Complex carbs, found in foods like whole grains, beans, and starchy veggies, give you steady energy over a longer time. They take longer to digest, so your body gets a constant flow of fuel.
Carbohydrates are said to be simple or complex depending on the time which elapses between the time when carbs are broken down into glucose and the time when the glucose is used up in the provision of energy. However, not all the carbohydrates are bad for your health as some are classified as complex carbohydrates. Soft and junk foods cause obesity and other diseases if taken in large quantities. To maintain good health, ensure you take more of natural foods such as brown rice, oats, and fresh fruits.
Why You Need Carbs
-
Immediate energy: Carbs provide glucose, the fuel that your body needs for anything from walking to thinking.
-
Stored energy: Any extra glucose that is produced is changed into glycogen and this can be used by the body in case of energy requirements.
-
Support for brain function: Glucose is the primary source of energy for your brain, so you need it to remain attentive and productive.
Proteins
Proteins play a vital role in building and repairing tissues. Every part of your body, from muscles to skin to organs, needs protein to stay healthy. When you eat protein-rich foods, they break down into amino acids, the tiny building blocks your body uses to create new cells.
Complete vs. Incomplete Proteins
There are 20 different amino acids, but not all proteins have them all.
-
Complete proteins, like those found in meat, poultry, fish, and dairy, contain all the essential amino acids your body needs.
-
Incomplete proteins, from sources like beans, lentils, and nuts, don’t have every amino acid, but you can combine different plant-based proteins throughout the day to get all the amino acids your body needs.
The Role of Protein in Your Diet
Protein is crucial for:
-
Muscle repair: After exercise or injury, protein helps rebuild muscle fibers.
-
Enzyme production: Enzymes that regulate digestion and metabolism are made from protein.
-
Immune function: Proteins help build antibodies, which keep your immune system strong.
Eating a variety of protein sources is key to a balanced diet. Opt for lean meats, fish, and plant-based proteins to get important vitamins and minerals. Avoid processed meats and fried foods, which can be high in unhealthy fats.
Fats
Fats get a bad rap, but they’re essential to your diet. They provide long-lasting energy, support brain function, and help your body absorb important vitamins like A, D, E, and K. Without fats, many of your body’s systems wouldn’t work as well.
Types of Fats
Fats come in different forms, and not all are created equal:
-
Saturated fats: These fats are saturated and are present in butter and cheese from animals and coconut and some other vegetable oils. High intake of saturated fats is known to contribute to heart diseases.
-
Monounsaturated fats: These are the monounsaturated fatty acids in olive oil, avocados and nuts they decrease the level of LDL cholesterol and may decrease the incidence of cardiovascular diseases.
-
Polyunsaturated fats: This includes omega-3 and omega-6 fatty acids which are found in fish, flax seed and walnut respectively and are crucial in the brain and reducing inflammation.
Why Fats Are Important
Healthy fats play an important role in:
-
Brain function: You’re still getting lots of fat in your diet, but the good kind – the kind that your brain, which is mostly fat, needs to maintain crispness.
-
Inflammation control: Omega-3 fatty acids have anti-inflammatory properties in the body since inflammation is related to most chronic diseases.
-
Cell growth: Fats also help the body build and repair your cells which are the skin and hair.
How to Balance Your Macronutrients
Balancing between carbohydrates, proteins, and fats is crucial in order to have energy, being thin, and being healthy. Of course, nobody knows where the right balance is, it depends on a person. It varies according to your gender, the age, level of activity, and any health goals you may have.
Here’s a simple breakdown for a healthy, balanced diet:
-
Carbohydrates: Take up 45-65 percent of your daily calories. Whole grains, fruits and vegetables should be the main foods that people should consider taking.
-
Proteins: Ideally, choose 10-35% of your daily calories from protein sources such as lean meat, fish, eggs, beans and plant protein sources.
-
Fats: Limit your intake of fats to between 20-35% of your total calorie intake and ensure you are taking healthy fats such as olive oil, nuts, seeds and fish.
Tips for a Balanced Diet
-
Eat a variety of foods: These should include whole grain products, lean meat, fish and other sources of protein, healthy oils and fats and fresh fruits and vegetables.
