Certain toxins found in common food can make you fat, says an expert.
According to Stephen Perrine, author of "New American Diet," there are all sorts of chemicals in foods, pesticides, growth hormones, antibiotics, and plastic pollutants, to name a few.
He says they are not only bad for the environment, but can also harm human bodies.
The chemicals that disrupt the function of our hormonal system are called obesogens, reports CBS News.
Obesogens can cause heart disease, diabetes, obesity, and high cholesterol.
These chemicals can be found in many of the most popular foods we eat and enter our body through a variety of sources: natural compounds found in soy products, artificial hormones fed to the animals we consume, plastic pollutants in some food packaging, chemicals added to processed foods, and pesticides sprayed on our produce.
