Answer;

-Sodium

Because Andy has high blood pressure and heart disease, he must lower his intake of Sodium.

Explanation;

-Eating substances rich in sodium such as salt raises the amount of sodium in the bloodstream and wrecks the delicate balance, reducing the ability of the kidneys to remove the water. The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.

-Therefore, for an individual with high blood pressure and heart disease like the case of Andy, he or she must lower the intake of sodium.

The answer is; saturated fats / Low-Density Lipids cholesterol

This means that Andy needs to avoid animal fats and prefer plant oils (high is High-Density Lipids). Saturated oils will exacerbate his condition since these fats settle in the walls of blood vessels causing plaque and arteriosclerosis. This reduced the lime of the vessels causing increased blood pressure.
