Worked Solution & Example Answer:A diet that is high in fat can lead to an increase in the total cholesterol levels in the blood - Edexcel - GCSE Biology - Question 6 - 2015 - Paper 1
Step 1
Calculate the percentage increase in total cholesterol level in the blood over this 10-year period.
Answer
To calculate the percentage increase in total cholesterol:
-
Identify the initial and final values:
- Initial cholesterol level 10 years ago: 4.8 mmol per dm²
- Final cholesterol level present day: 6.0 mmol per dm²

Explain why this man has been advised to eat mycoprotein rather than meat.
Answer
The man has been advised to eat mycoprotein rather than meat for several reasons:
-
Lower Cholesterol Content: Mycoprotein, derived from fungus, typically has lower levels of saturated fat compared to meat, which can help manage cholesterol levels.
-
Healthier Alternative: It is a source of plant-based protein that contains no cholesterol and can aid in maintaining a healthier diet.
-
Cardiovascular Health: Reducing intake of high-cholesterol foods, like red meat, can lower the risk of cardiovascular diseases, making mycoprotein a better option for someone with elevated cholesterol levels.
Overall, incorporating mycoprotein into his diet is a beneficial strategy to improve his health and manage cholesterol levels effectively.
