Are there foods i should avoid while taking anastrozole?

No: I am unaware of any foods that interact with the effects of anastrozole.

Low fat diet: When the ovaries no longer synthesize oestrogen, the peripheral lipocyte or fat cell creates e1---> e3. This "peripheral conversion" is a target for chemotx against hormone sensitive breast ca. Patients should avoid dietary fats, transfat, high cholesterol, etc. As much as possible, as any weight gain in the form of fat seemingly negates the effect of anastrozole...
