There are three macronutrients that the body can use for fuel. They include fat, protein, and carbohydrates.
Fats are essential for multiple functions of the human body. They are the building blocks for your cell membranes, assist in the absorption of fat soluble vitamins, slows down the speed of digestions, and make your food taste great! Great sources of fat include grass fed butter, grass fed ghee, organic coconut oil, cold pressed olive oil, grass fed grass finished fatty cuts of meat, pasture raised eggs, avocado, and macadamia nuts.
Carbohydrates are made up for sugars and are predominantly found in vegetables, fruit, legumes, grains, and sweeteners. Carbohydrates are broken down into glucose in the body and can be used for a quick source of fuel for the brain and muscles.
Proteins are made up of amino acids and are the building blocks for your muscles, tissues, organs, and more. While some plants contain protein, animal sources contain the essential amino acids, and are the most bioavailable sources. Great sources of protein include wild caught fish, grass fed and grass finished or pastured raised animals and pasture raised eggs.
