Tag: USDA macronutrient recommendations
So check this out, your body has the amazing ability to take the foods you eat and literally turn them into you. Pretty cool don’t you think! Whether you eat an apple, a steak or a kale salad, your body is able to break that food down into its chemical parts and reassemble those parts into your cells and the energy you use all day. This is flat out awesome considering outside the plant and animal kingdom, nothing else can do that!
Here is the deal though, your body is only as amazing as the material it has to work with, like a fine tuned machine, the quality of the food you put into your amazing body has a huge impact on your overall health. An apple is not just an apple, nor is a steak just a steak. As stated above, your body is able to break those foods down into their chemical parts, like macronutrients and micronutrients. So what makes these nutrients so important, lets take a closer look!
What Are Macronutrients:
Macronutrients are nutrients that provide calories or energy. Derived from the prefix makro (Greek), which means big or large, used because macronutrients are required in large amounts. There are three broad classes of macro-nutrients which make up your primary food sources know as proteins,carbohydrates and fats.
The main function of macronutrients is to provide energy, counted as calories. While each of the macronutrients provides calories, the amount provided by each varies. Carbohydrates provides four calories per gram (I think we are all pretty well versed here),proteins;also four, while fats provides nine calories per gram.
Macronutrients also have specific roles in maintaining the body and contribute to the taste, texture and appearance of foods, which helps to make the diet more varied and enjoyable.
Macronutrients broken down:
- Carbohydrates – are required for energy. As diabetics we all have varying opinions on carbohydrates and the amounts that we like to ingest , but glucose, which is a monosaccharide, is the most essential source of energy in the body. The brain works entirely on glucose alone. When an immediate source of energy is required, glucose is converted into glycogen which is stored in the liver. When energy is needed it is converted into glucose again and used to release energy. Carbohydrates provide 4 calories of energy per gram.
- Fats – have the highest caloric content. This means they provide the largest amount of energy when burnt. When measured by a calorimeter, fats provide about 9 calories per gram, making them twice as energy-rich than protein and carbohydrates. Extra fat is stored in adipose tissue and is burnt when the body has run out of carbohydrates. Fat is also needed to take up fat-soluble vitamins.
- Proteins– are the third and last source of energy. They are the last to be used of all macronutrients. In cases of extreme starvation, the muscles in the body, that are made up of proteins, are used to provide energy. This is called muscle wasting. Proteins also provide 4 calories per gram.
