Step 1
Describe (i) the nutritive value of fish.
Answer
Fish is a source of high biological value (H.B.V.) protein, which is essential for the growth and repair of tissues. The lipids in fish also provide polyunsaturated fatty acids, including Omega-3, which are beneficial for heart health. Fish contains no carbohydrates, making it suitable for low-carb diets. Additionally, certain fish are rich in vitamins A and D, particularly those that are oil-rich. Fish is a significant source of minerals such as iodine, zinc, fluorine, phosphorous, and potassium, and it can provide calcium, especially in species like canned fish.

Describe (ii) the dietetic value of fish.
Answer
Fish can be a substitute for meat, providing versatility in diets. It is particularly suitable for individuals at risk of heart disease due to its high content of polyunsaturated fats. Fish is easy to digest, making it a good option for the elderly and those recovering from illness. Its versatility allows it to be served easily with carbohydrate-rich foods, enhancing meal variety.
