Chops and sausages could be off the menu for women hoping to fall pregnant, thanks to a study linking them to infertility.
Sugar has also been singled out after researchers discovered the foods create a toxin that inflames the womb.
The new study has found that eating grilled and roasted meats, fried foods and sugar can lead to infertility in obese women.
When food is heated and proteins are exposed to sugar, toxic compounds are created called advanced glycation end products, or AGE's.
Researchers found these AGE's trigger inflammation in the womb lining, making it harder for embyos to implant.
They may also affect the development of the placenta, leading to pregnancy complications.
"It's known to be related to pre-eclampsia if there are problems with development in the placenta," Dr Jemma Evans said.

One in six Australian couples struggle to fall pregnant. Researchers say a change in diet could dramatically improve their chances.
Once a patient is eating healthily, a reduction in toxin levels can be seen in as little as four weeks.
"We hope that by lowering the advanced glycation end products in the diet, we can actually improve fertility," Dr Evans said.
Researchers will now conduct a clinical trial to prove their theory.
