One must be vigilant because certain foods, such as grapefruit, can interact dangerously with medications, although the risk is more moderate with the whole fruit than with its juice.

The interaction between grapefruit and certain medications is a well-documented pharmacological phenomenon, often cited in clinical journals (e.g., Canadian Medical Association Journal). The mechanism relies on the furanocoumarins present in the fruit, which inhibit an enzyme (CYP3A4) responsible for the metabolism of many treatments, thereby increasing their concentration in the blood to sometimes toxic levels. The assertion that the risk is lower with the whole fruit is consistent, as the concentration of these compounds is often more diluted or less bioavailable than in pure juice. This is not a generalization for all foods, but a specificity linked to this particular fruit. Research broadly confirms this risk for classes of medications such as statins or certain antihypertensives. The advice is therefore based on solid evidence and constitutes a relevant precautionary measure.
