Nutritionists and experts are always warning people about the dangers of eating too much fried food, but according to a study things could be worse than we ever thought possible and it will make you question whether you really want that next sausage butty.
According to a study from scientists in Italy, men could end up with penises half an inch smaller if their parents were exposed to high levels of a chemical that was found in non-stick frying pans.
Half an inch. No one can afford that.
The chemicals called PFCs can interfere with male hormones while in the womb and have been found to potentially lead to sexual organs being 'significantly' shorter...and thinner.
But it's not just during pregnancy that these chemicals can have an effect, researchers discovered they could affect teenagers as well.
Scientists found that the willies of men who were raised in places which had high levels of PFCs were around 12.5 percent shorter and 6.3 percent thinner than the average man.
The toxic substance is also found in waterproof clothing and grease-proof packaging for food, which can reduce testosterone levels.
The chemical was removed from Teflon products in 2013.
The study measured the penises of 383 men - at an average age of 18 - and was carried out at the University of Padua, one of four areas in the world known to have high levels of PFC pollution.
Dr Andrea Di Nisio, who led the researchers, said: "As the first report on water contamination of PFCs goes back to 1977, the magnitude of the problem is alarming.
"It affects an entire generation of young individuals, from 1978 onwards."
According to studies that have been carried out into the chemical, they are also linked to issues such as low birth weight, high cholesterol, and bladder cancer - but their potentially cancer-causing effects are not fully understood.
The chemicals are absorbed by the intestines from food and drinking water, or even breathed in and can then enter the bloodstream, and can prove toxic for foetuses when consumed by the mother.
For men this can mean smaller penises.
In Dr Di Nisio's study, the penises were measured of 212 men who grew up in an area with high exposure to PFCs, and 171 men from elsewhere. However, all were from the region of Veneto which is highly polluted because run-off from a chemical factory found its way into a major river and the drinking water.
The average flaccid penises of men who weren't exposed were measured at 10cm (3.9ins) - from body to tip - with those in the polluted areas just 8.75cm (3.4ins).
Their penises were also thinner; the healthy men measured 10.3cm (4ins) in circumference compared to 9.65cm (3.7ins) for the contaminated penises.
The research was published in the Journal of Clinical Endocrinology and Metabolism.
