Which of the following statements is true?

Question

Accepted Answer

Option 2 is the correct answer because linolenic acid is indeed an Essential Fatty Acid (EFA). Essential Fatty Acids are types of fats that the body cannot synthesize on its own and must be obtained through the diet. Linolenic acid, specifically alpha-linolenic acid (ALA), is an omega-3 fatty acid that is crucial for maintaining cell membrane integrity, supporting cardiovascular health, and playing a role in brain function and development.

Now, let's explain why the other options are incorrect:

1. **Option 1: Cashewnuts and walnuts are rich sources of cholesterol.**
   - This statement is incorrect because cashewnuts and walnuts do not contain cholesterol. Cholesterol is found in animal products, and both cashewnuts and walnuts are plant-based foods. Instead, these nuts are rich in healthy fats, including monounsaturated and polyunsaturated fats, which can actually help lower cholesterol levels in the body.

3. **Option 3: Phenyl Alanine is a non-essential Amino Acid.**
   - This statement is incorrect because phenylalanine is an essential amino acid. Essential amino acids are those that the body cannot produce on its own and must be obtained from the diet. Phenylalanine is necessary for the production of proteins and other important molecules in the body, such as neurotransmitters.

4. **Option 4: All options are correct.**
   - This option is incorrect because, as explained above, Options 1 and 3 contain false statements. Therefore, not all options can be correct.

In conclusion, Option 2 is the correct answer because linolenic acid is indeed an Essential Fatty Acid, while the other options contain inaccuracies regarding the nature of cholesterol in nuts and the classification of phenylalanine.
