| 1 | Define essential nutrients | Essential nutrients are those that the body cannot produce on its own and must be obtained through diet. | None |
| 2 | Explain the role of amino acids in muscle meals | Amino acids are the building blocks of protein, which is essential for muscle growth and repair. | None |
| 3 | Differentiate between complete and incomplete protein sources | Complete protein sources contain all essential amino acids, while incomplete protein sources lack one or more essential amino acids. | None |
| 4 | Discuss the importance of branched-chain amino acids (BCAAs) | BCAAs, specifically leucine, isoleucine, and valine, are important for muscle protein synthesis and preventing muscle protein breakdown. | None |
| 5 | Explain the concept of nitrogen balance | Nitrogen balance is the difference between the amount of nitrogen consumed and the amount excreted. A positive nitrogen balance indicates that the body is in an anabolic state, while a negative nitrogen balance indicates a catabolic state. | None |
| 6 | Discuss dietary requirements for protein | The recommended daily intake of protein varies based on factors such as age, sex, and activity level. Generally, it is recommended to consume 0.8 grams of protein per kilogram of body weight. | Consuming too much protein can lead to kidney damage and other health issues. |
| 7 | Compare plant-based and animal-based proteins | Plant-based proteins tend to be incomplete and have a lower digestibility score than animal-based proteins. However, they can still be combined to create complete protein sources. Animal-based proteins tend to be complete and have a higher digestibility score. | Animal-based proteins can be high in saturated fat and cholesterol, which can increase the risk of heart disease. Plant-based proteins may not provide enough of certain essential amino acids. |
| 8 | Explain the concept of protein quality | Protein quality refers to the ability of a protein source to provide all essential amino acids in the right proportions. | None |
| 9 | Discuss protein turnover and muscle protein breakdown | Protein turnover is the balance between muscle protein synthesis and muscle protein breakdown. Muscle protein breakdown can occur during exercise or periods of fasting, and can be prevented by consuming protein-rich meals. | None |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| All amino acids are essential for muscle growth. | Only the nine essential amino acids (EAAs) cannot be produced by the body and must be obtained through diet or supplementation to support muscle growth. Non-essential amino acids can also contribute to muscle building, but they are not required in the same way as EAAs. |
| Plant-based protein sources do not contain all of the essential amino acids needed for muscle growth. | While some plant-based proteins may lack certain EAAs, it is possible to obtain all nine EAAs from a well-planned vegetarian or vegan diet that includes a variety of protein sources such as legumes, nuts, seeds, and grains. Additionally, there are now many plant-based protein supplements available that contain all nine EAAs. |
| Consuming large amounts of protein will automatically lead to increased muscle mass. | While consuming adequate amounts of high-quality protein is important for supporting muscle growth and repair, simply increasing overall protein intake without also engaging in regular resistance training will not necessarily result in increased muscle mass. The body can only use so much dietary protein at one time; excess amounts will either be excreted or stored as fat if calorie intake exceeds energy needs. |
| Animal-based proteins are superior to plant-based proteins for building muscles. | Both animal- and plant-based proteins can provide sufficient quantities of EAAs necessary for building muscles when consumed in appropriate quantities and combinations with other foods throughout the day while following an active lifestyle including strength training exercises regularly. |
| Protein shakes should always be consumed immediately after exercise. | While consuming a post-workout meal containing carbohydrates and high-quality protein within 30 minutes after exercise has been shown to enhance recovery compared with waiting several hours before eating , timing isn’t everything . What matters most is meeting daily macronutrient requirements over time rather than focusing on specific nutrient timing windows. |
