What are macro-nutrients?

Macronutrient has this cool thing where the definition is actually embedded in the name itself. Macro meaning big and nutrient meaning something that nourishes you. This describes molecules that are in our food that are measured in large quantities that nourish us. Their are three basic macronutrients that are found in our food, these three macronutrients are Fats, Carbohydrates, and Proteins. Each macronutrient has different chemical structures that are in our food. The structure of the chemical determines the function in our body.  

Whats Carbohydrates?

Carbohydrates or its famous nickname Carbs, What exactly is it and what does it do? The first thing that usually comes to a person's mind when thinking carbohydrates are starches, and sugars. Carbs are the fiber, sugars, and starches found in foods. Lets look further, most carbohydrates are categorized as MonosaccharidesDisaccharides, and Polysaccharides, the term Saccharide is just another term for sugar. Mono, Di, and Poly are prefixes that refer to the number of sugars in the molecule. Mono meaning a carbohydrate made up of one unit of sugar, Di meaning two units of sugar, and Poly being many units. To simplify this, carbohydrates are chains of sugar generally speaking. 

Carbohydrates can be divided into two categories. Simple Sugars that house Monosaccharides(Glucose, Fructose, Galactose) and Disaccharides(Maltose, Sucrose, Lactose), and Complex Carbohydrates that houses Polysaccarides. Simple Sugars are comprised of refined sugars and are readily available for the body to immediately use as an energy source that burns out faster. Examples are, Honey, Sugar, fruit juices, milk, soda, candy, and white breads. Complex Carbs takes time to process in the body helping to more effectively release energy and being a longer lasting source of energy for the body do to high amounts of nutrients and vitamins that can be found in complex Carbohydrates. Examples are Brown rice, oats, and vegetables.


Protein are more than just foods, proteins are made up of a string of smaller building blocks called Amino Acids. Protein has many job descriptions, Protein helps make up genes, organs, Neurotransmitters, skin, blood, hormones, antibiotics, hair, and tissues. 


Fat is an important nutrient that the body needs in order to function. Fat just like Carbohydrates are an energy source for the body. It can be known as the secondary energy source here in the United States, almost like a freezer that has stored food when the fridge(carbs) has emptied. Its an energy reserve. The different forms of fats are Saturated, Trans, Triglycerides, monosaturated, polysaturated, and Omega 3, 6. Saturated and trans fats are considered unhealthy, while unsaturated and polysaturated fats are considered healthy. Omega's are polysaturated. 


Micronutrients are the smaller nutrients, such as vitamins, minerals, digestive enzymes, and probiotics. 


Vitamins are the building blocks that keeps the body running. Vitamins are organic compounds we need to ingest in small amounts. Vitamins are the maintenance workers for the body.

Minerals divided into three categories:

Insulin is the storage hormone produced in the Pancreas. Insulin's job is to get excess sugar out of the blood to stabilize blood sugar levels. Too much Insulin creates problems(Type II Diabetes), and when your body isn't creating insulin at all, or very little, this too is a problem(Type I Diabetes). So yes, insulin has an important role. Insulin can be manipulated through the food we eat and through our style of eating.

Blood Sugar

Blood Sugar is the sugar that is found within your blood. The Liver controls blood sugars when you are not eating and the Pancreas controls blood sugars when you are eating.
