A.
Salmon
B.
Hard-boiled eggs
C.
Cottage cheese
D.
Whole wheat bread
E.

The correct answer and Explanation is :
The correct answers for sources of complete proteins are:
A. Salmon
B. Hard-boiled eggs
C. Cottage cheese
Explanation:
Complete proteins contain all nine essential amino acids that the body cannot synthesize on its own, making them crucial for various bodily functions, including tissue repair and immune system support. Foods that are considered complete proteins are typically of animal origin, though some plant sources are also complete.
- Salmon: As a fish, salmon is an excellent source of complete protein. It provides all essential amino acids, along with omega-3 fatty acids, which are beneficial for heart health and reducing inflammation.
- Hard-boiled eggs: Eggs are one of the best sources of complete protein. They contain all the essential amino acids and are also rich in vitamins and minerals, making them a nutritious choice for anyone on a high-protein diet.
- Cottage cheese: This dairy product is another complete protein source. It is high in protein while being relatively low in fat (depending on the variety) and is a good option for those looking to increase their protein intake.
On the other hand:
- D. Whole wheat bread: This is considered an incomplete protein because it lacks one or more of the essential amino acids. Whole grains like bread primarily provide carbohydrates, though they can contribute to overall protein intake when combined with other protein sources.
- E. Steamed spinach: While spinach is nutritious and provides some protein, it is also an incomplete protein. Like many vegetables, it does not contain all the essential amino acids.
In summary, for a high-protein diet, focusing on complete protein sources like salmon, eggs, and cottage cheese is important for ensuring adequate amino acid intake necessary for optimal health.
