Mediterranean-type diet improves odds of pregnancy.

Women being treated for infertility are 1.4 times more likely to become pregnant if they consume a diet high in fruits, vegetables, legumes, whole grains and some fish. Dutch researchers also found these women had a low intake of snacks, meats, and mayonnaise.

More research is needed to determine whether it was fish or plant-based foods that gave the benefit.
