Which food should not be taken with anti-hyperlipidemic medications?

Grapefruit juice should not be taken with anti-hyperlipidemic medications because it can interfere with the metabolism of certain drugs, notably statins, which are commonly prescribed to manage cholesterol levels. Grapefruit contains compounds that inhibit the cytochrome P450 3A4 enzyme, which plays a critical role in breaking down many medications in the liver. When this enzyme is inhibited, it can lead to higher levels of the medication in the bloodstream, increasing the risk of adverse effects and toxicity.

In contrast, milk contains calcium and protein, which can bind with certain medications and reduce absorption, but it does not cause the same metabolic interference as grapefruit juice. Iron supplements, while they can interact with other medications in terms of absorption, do not have the same specific enzymatic interaction with anti-hyperlipidemic drugs as grapefruit does. Therefore, avoiding grapefruit juice is essential for maintaining the safety and efficacy of anti-hyperlipidemic therapy.
