Final answer:
Meat is not a source of carbohydrates but is rich in protein. For dietary carbohydrates, one should consume grains, vegetables, and fruits which are natural sources of this macronutrient. Carbohydrates play a key role in energy supply and in sparing proteins for repair and growth in the body.
Step-by-step explanation:
False. Meat is not a good source of carbohydrates; it is primarily a source of protein and, depending on the cut, fat. Carbohydrates are macromolecules that supply energy to the body through glucose, and are found in foods such as grains, fruits, vegetables, and beans. Meat, on the other hand, provides essential amino acids and is an important component of a balanced diet, but for carbohydrates, one should look to foods like whole grain breads, pasta, and vegetables, such as acorn squash, which are high in this nutrient.
Energy from carbohydrates is vital for both day-to-day function and for athletes who need a quick source of energy during competition, which is why they 'carb-load' before events. Furthermore, carbohydrates and fats play a protein sparing action by supplying the energy needed by the body, allowing proteins to be used for anabolic purposes, such as tissue repair and growth.
