oils can inflict damage is by converting your good cholesterol into bad cholesterol ? by oxidizing it . When you cook with polyunsaturated vegetable oils ( such as canola , corn , and soy oils ), oxidized cholesterol is introduced into your system .
As the oil is heated and mixed with oxygen , it goes rancid . Rancid oil is oxidized oil and should NOT be consumed ? it leads directly to vascular disease . Trans-fats are introduced when these oils are hydrogenated , which increases your risk of chronic diseases like breast cancer and heart disease .
So what ? s the best oil to cook with ?
Of all the available oils , coconut oil is the oil of choice for cooking because it is nearly a completely saturated fat , which means it is much less susceptible to heat damage . And coconut oil is one of the most unique and beneficial fats for your body . For more in-depth information about the many benefits of coconut oil , please see this special report . Olive oil , while certainly a healthful oil , is easily damaged by heat and is best reserved for drizzling cold over salad .
5 . Microwave Popcorn
Perfluoroalkyls , which include perfluorooctanoic acid ( PFOA ), and perfluorooctane sulfonate ( PFOS ), are chemicals used to keep grease from leaking through fast food wrappers , are being ingested by people through their food and showing up as contaminants in blood . Microwave popcorn bags are lined with PFOA , and when they are heated the compound leaches onto the popcorn .
These chemicals are part of an expanding group of chemicals commonly referred to as ? gender-bending ? chemicals , because they can disrupt your endocrine system and affect your sex hormones . The EPA has ruled PFCs as ? likely carcinogens ,? and has stated that PFOA ? poses developmental and reproductive risks to humans .? Researchers have also linked various PFCs to a range of other health dangers , such as :
Infertility ? A study published in the journal Human Reproduction found that both PFOA and PFOS ( perfluorooctane sulfonate ), dramatically increased the odds of infertility . PFOA was linked to a 60 to 154 percent increase in the chance of infertility .
Thyroid disease ? A 2010 study found that PFOA can damage your thyroid function . Individuals with the highest PFOA concentrations were more than twice as likely to report current thyroid disease , compared to those with the lowest PFOA concentrations . Your thyroid contains thyroglobulin protein , which binds to iodine to form hormones , which in turn influence essentially every organ , tissue and cell in your body . Thyroid hormones are also required for growth and development in children . Thyroid disease , if left untreated , can lead to heart disease , infertility , muscle weakness , and osteoporosis .
Cancer ? PFOA has been associated with tumors in at least four different organs in animal tests ( liver , pancreas , testicles and mammary glands in rats ), and has been associated with increases in prostate cancer in PFOA plant workers .
Immune system problems ? Several studies by scientists in Sweden indicate that PFCs have an adverse effect on your immune system . As described in a report on PFCs by the Environmental Working Group ( EWG ), PFOA was found to decrease all immune cell subpopulations studied , in the thymus and spleen , and caused immunosupression .
Increased LDL cholesterol levels ? A 2010 study in the Archives of Pediatric & Adolescent Medicine5 found that children and teens with higher PFOA levels had higher levels of total cholesterol and LDL or ? bad ? cholesterol , while PFOS was associated with increased total cholesterol , including both LDL cholesterol and HDL or ? good ? cholesterol .
