Table 1 shows the percentage change in the flow rate of a blood-mimicking fluid through synthetic micro-vessels (acting as an in vitro model for coronary arteries) after continuous exposure to different dietary lipid emulsions for 14 days.
| Lipid emulsion | Percentage change in flow rate (%) |
|---|---|
| Distilled water | 0.0 |
| Olive oil | +1.8 |
| Corn oil | +0.5 |
| Palm oil | -7.2 |
| Butter | -14.5 |
Explain why a diet rich in unsaturated fats (such as olive oil) is better for cardiovascular health than a diet rich in saturated fats (such as butter).
Use data from Table 1 in your answer.
