What are carbohydrates?
Carbohydrates are macronutrients. A carb alludes to a specific subatomic structure. It is a
sequence of carbons with a water particle connected to each of them.
, Discuss the role of carbohydrates in the body. Where are carbohydrates found? Discuss the
daily recommendations for carbohydrates in adults based on the RDA? If someone is
active, do these recommendations change?
Carbohydrates are found in a diversity of foods, including grains, fruits, vegetables, milk, yogurt,
beans, nuts and seeds (Coleman, R.D., L.D.; 2018). The Recommended Daily Allowance, or
RDA, for carbohydrates is the percentage of your total calorie intake that should come from
carbs each day. Carbohydrates should make up the largest percentage of your calories, compared
with protein or fat, but the carb RDA is quite variable. According to the Institute of Medicine,
the carbohydrate RDA is 45 to 65, meaning 45 to 65 percent of your daily calories should come
from carbs (Coleman, R.D., L.D.; 2018). Carbohydrates are the body’s main supplier of energy.
They’re found in practically all the foods that we eat but choosing the right ones can make or
break a heart-strong diet. A positive outcome is eating carbohydrates stimulates the production of
serotonin, a brain chemical that impacts mood and appetite.
Carbohydrates are one of the most important nutrients needed in an active person’s diet.
Carbohydrates make available the fuel you use as energy for physical activity, brain function and
organ function (Willi Foodie, 2013). As physical activity increases, muscle glycogen (where we
store sugars) becomes used up, which causes a higher need for carbohydrates. For kids and
adolescents involved in high intensity athletic activities, eating the right amount of carbohydrates
before, during, and after an event is very vital! Frequently, teenage boys are fooled into thinking
low-carb and high protein diets will help them gain significant muscle mass. This is NOT true. A
diet low in carbs will not only decrease muscle potential; it will also deteriorate overall athletic
performance (In Motion Fitness, Inc; 2014)
