You should also avoid alcohol, smoking and exercise. If you take medications, continue taking them as normal unless your doctor says otherwise.
Food and drinks can affect your results because sugar, fats, enzymes, minerals and cholesterol all absorb into your blood stream. Affected results could then lead to an inaccurate diagnosis.
If you forget and eat or drink something, call your doctor or lab and ask if the test can still be done. They can then tell you if you need to reschedule your test.
