12 Health Dangers of Cooking Food at High Temperatures

  • 2 of 4

7. Oxalic acid, which occurs in over 50 fruits and vegetables, becomes harmful when cooked. This includes such powerfoods as spinach and dandelion greens. The calcium binds with the oxalic acid in the blood to neutralize it, forming calcium compounds that are difficult for the body to excrete; this may lead to kidney stones.

8. White blood cells increase when food is cooked; the body reacts to cooked food in the same way it reacts to infection.

9. Cooked fiber passes through the digestive system more slowly than raw food. It is then more likely to ferment, causing toxins, gas and heartburn. Cooked foods can take up to 24 or 48 hours or longer to digest—hard work for the body for a few nutrients!

10. The pancreas enlarges as a result of over-stimulation from cooked food; eventually it breaks down, according to studies. Years of abuse to the pancreas cause it to secrete fewer enzymes which may cause digestive problems or diabetes.

11. Unsaturated oils in cooked foods become rancid within a few hours, even in the refrigerator. The saturated fat and trans fat in deep-fried foods increase your risk for high cholesterol and heart disease. Deep-fried foods also may contain acrylamide, a possible carcinogen; foods fried at higher temperatures or for longer contain more than those fried for shorter times or at lower temperatures.

12. All processed foods are cooked foods, which come with packaging that is polluting this world.

Great article it's amazing how much there is to know, yet most of us don't, so a very important read.

Thanks for the information. I'm moving on my own soon and intend to do as little cooking as possible.

After tens of thousands of years of cooking, why are we suddenly attacking it now? Some foods are meant to be eaten raw and some cooked. Some both ways. I just stay away from burnt and processed meat.

It has long been suggested that barbecues are a great danger of exposure to cancer causing substances, or anything blackened.

Meat, by itself is a danger and humans need not eat it, but if you chose to do so, think...moderation.

Thanks for sharing.

This was quite an eye-opener for me which leads me to say, thank you for the excellent info.

I didn't know that cooking food changes the consistency to be more acidic. Another thing I learned was that raw food is digested more easily and quickly. There would be more fibre in raw food, so presumably that would be the reason.

Light steaming would preserve more enzymes, but perhaps not as healthy as eating raw food. I would love to eat blueberries every day - but they're not available year-round.

Thanks again - I love learning info that's helpful to my health !
