Does the bioavailability of certain foods changes when eaten with other foods?

When I saw "studies on the bioavailability of zinc in man: II absorption of zinc from organic and inorganic sources", I was intrigued. Are there such things as anti-nutrients, i.e. are there some things which impair the absorption of nutrients, vitamins and minerals?

Depends. IIRC absorbtion of iron can depend a lot on what its eaten with. Vitamin C, acidic foods, proteins etc. making it easier to digest and grains, calcium, spinach, coffee etc. making it harder to digest. Iron is just one very spesific example of course.
